Researchers Reveal Mechanism that Impairs Blood Flow with Aging

The Physiological Society’s Journal of Physiology recently published a study led by Erika Boerman, identifying an age-related cause of arterial dysfunction.

 

 

With the world’s elderly population expected to double by 2050, understanding cardiovascular disease, the No. 1 cause of death worldwide, is often highlighted and now University of Missouri researchers have identified an age-related cause of arterial dysfunction, a finding that could lead to future treatments.

“Aging affects everyone and causes changes throughout our bodies,” said Erika Boerman, a post-doctoral fellow in the Department of Medical Pharmacology and Physiology at the MU School of Medicine and lead author of the study. “We found that older arteries had a significantly lower number of sensory nerves in the tissues surrounding them and they were less sensitive to an important neurotransmitter responsible for dilation.”

Boerman’s study focused on mesenteric arteries ― a type of artery that supplies blood to the small intestines ― of mice that were 4 months and 24 months old. These ages correspond to humans in their early 20s and mid-60s, respectively. Without stimulation, the diameter of the blood vessels of both younger and older mice was approximately the same. However, when stimulated to induce dilation, differences between the age groups became apparent.

“The younger arteries dilated as expected,” Boerman said. “However, when we performed the same stimulation to the arteries of older mice, the vessels did not dilate. When we examined the presence of sensory nerves, we noted a 30 percent decrease in the amount surrounding the older arteries compared to the younger arteries.”

Additionally, the researchers found that even when purposefully exposing older mesenteric arteries to defined amounts of the neurotransmitter calcitonin gene-related peptide, or CGRP, the arteries’ ability to dilate was greatly reduced.

“Poor neurotransmitter function and a reduced presence of sensory nerves surrounding older vessels lead to age-related dysfunction of mesenteric arteries,” Boerman said. “The importance of this discovery is that if we can identify why this happens to mesenteric arteries, it may be possible to prevent the same thing from happening to other blood vessels throughout the body.”

More research is needed to understand why aging affects sensory nerve distribution and neurotransmitter performance. However, identifying this new mechanism of vascular dysfunction opens the door for future studies that could eventually lead to the treatment of health issues such as stroke and cardiovascular disease.

The study was published in The Physiological Society’s Journal of Physiology.

Blood Vessels Can Actually Get Better With Age

Although the causes of many age-related diseases remain unknown, oxidative stress has been linked to cardiovascular and neurodegenerative diseases including diabetes, hypertension and age-related cancers.

However, researchers at the University of Missouri recently found that aging actually offered significant protection against oxidative stress, suggesting that aging may trigger an adaptive response to counteract the effects of oxidative stress on blood vessels.

“Molecules known as reactive oxygen species, or ROS, play an important role in regulating cellular function,” said Steven Segal, at the MU School of Medicine and senior author of the study. “However, the overproduction of ROS can help create a condition referred to as oxidative stress, which can alter the function of cells and interfere with their growth and reproduction.”

To understand the effects of aging on the function of blood vessels when they are exposed to oxidative stress, Segal’s team studied the inner lining, or endothelium, of small resistance arteries. Resistance arteries are important to cardiovascular function because they regulate both the amount of blood flow into tissues and systemic blood pressure.

“We studied the endothelium from resistance arteries of male mice at 4 months and 24 months of age, which correspond to humans in their early 20s and mid-60s,” Segal said. “We first studied the endothelium under resting conditions and in the absence of oxidative stress. We then simulated oxidative stress by adding hydrogen peroxide.

When oxidative stress was induced for 20 minutes, the endothelial cells of the younger mice had abnormal increases in calcium when compared to the endothelial cells of the older mice. This finding is important because when calcium gets too high, cells can be severely damaged.”

When oxidative stress was extended to 60 minutes, Segal’s team found that the death of endothelial cells in the younger mice was seven times greater than those from the older mice. These findings indicated that with advancing age, the endothelium had adapted to preserve cellular integrity when confronted with oxidative stress.

“This finding contrasts with the generally held belief that the functional integrity of the endothelium is compromised as we age. Our study suggests that blood vessels adapt during the aging process to regulate ROS and minimize cell death when subjected to an abrupt increase in oxidative stress. This adaptation helps to ensure that the arteries of older individuals can still do their jobs.”

The study was published in the Physiological Society’s Journal of Physiology.

Selena Gomez has silently updated her Facebook page with a nude picture sending shock waves across the globe, especially for her fans.

 

Star of “Wizards of Waverly Place”, Selena has been a symbol of deceny for long and her break up with boyfriend Justin Biber has hurt more of their fans than the couple themselves who have carved out their own niche area of expertise and fame.

The nude picture uploaded on September 8 on Facebook has already received more than 1,956,794 likes and 15,160 have shared the page. However, some comments were outrageous, while others just applaud the beauty behind the photo.

Arif Munir was first to compare her to another Miley Cyrus on the cards while Gyzelle Rodriguez wanted to be more artistic in his appreciation when he said: “Girl! You are beautiful! There is a huge difference between miley naked and selena naked. Its called class. Selena brings the art out of the female form. Miley brings out vulgarity.”

Laser Breakthrough Could Speed up Self-Driving Cars on to Roads

Google’s self-driving car relies on a roof-mounted LIDAR sensor to see the world around it.

 

Researchers at the University of California, Berkeley say they’ve developed a new breed of laser technology that could significantly reduce the size, weight, cost, and power consumption of LIDARs, potentially leading to a much broader range of autonomous vehicles.

LIDAR is a portmanteau of “light” and “radar.” In essence, these sensors monitor their surroundings by shining a light on an object and measuring the time needed for it to bounce back. They work well enough, but they aren’t without their drawbacks. Today’s self-driving cars typically use LIDARs that are quite large and expensive. Google, for instance, used $80,000 LIDARs with its early designs. “Most vehicles in the DARPA urban challenge put half-a-million-dollars worth of sensors on the car,” says Daniela Rus, the director of MIT’s Computer Science and Artificial Intelligence Laboratory, referring to the government-backed competition that helped spawn Google’s autonomous vehicles.

“This is important for unmanned vehicles on land and in the sky,” says Weijian Yang, one of the researchers behind the project.

Yang’s work is part of a wider effort to refine LIDARs and build a cheaper breed of autonomous cars and other vehicles. A German company called SICK already offers a LIDAR that sells for less than $10,000, and researchers from MIT and the National Research Foundation of Singapore, including Rus, recently built a self-driving golf cart using no more than four of these units (see video below).

As LIDAR technology improves—and as we improve the algorithms that process the data gathered from these sensors—we’ll bring autonomy not just to cars but smaller contraptions, including golf carts, robots, and flying drones.

Anatomy of a LIDAR

A LIDAR operates by repeatedly changing the wavelength of a laser, so that the sensor can properly identify the light as it bounces off an object and returns to the sensor, and such wavelength changes require the precise manipulation of a mirror—or sometimes multiple mirrors. Typically, a separate electrical device moves these mirrors to and fro. But at Berkeley, Yang and his team developed a new option. They can move the mirrors with the laser itself.

“You don’t need an external electrical source,” says Yang, the lead author on the paper describing the technology, which was published today in the journal Scientific Reports. “The laser can change the position of the mirror automatically. The light has some kind of force.”

The result: they don’t need that outside electrical device, the sensor is smaller and lighter, and it consumes less power. The laser can be integrated with the mirror. The whole device can squeeze into a few hundred square micrometers of space. And it can be powered with the equivalent AA battery.

A More Accurate Picture

According to Yang, this same technology could improve optical coherence tomography, or OCT, which is used in medical imaging equipment. But the most intriguing possibilities lie in the world of robotics. Among other things, Yang explains, Berkeley’s method allows lasers to change wavelengths more frequently—one microsecond versus 10 or so milliseconds—and that means a LIDAR could potentially take more readings, more quickly. In other words, it could provide a more accurate picture of its surroundings.

Emilio Frazzoli, an MIT researcher who worked alongside Rus on those self-driving golf carts, says that smaller, cheaper LIDARs aren’t essential to the near future of self-driving cars. “Right now, these sensors are still expensive, but they’re becoming better and cheaper, and I don’t see them as a bottleneck,” he says, pointing out that even with today’s sensors, the price of a self-driving car compares favorably to how much you’d speed for a standard car and a full-time driver.

But he says that better sensors are certainly welcome, particularly for other applications. Indeed, Yang believes that his work could help drive the creation of additional autonomous vehicles and robots, including contraptions the size of a smartphone. In the years to come, more machines will have eyes than you might expect.

Crocodiles Set to Face Extinction, Says Australian Researcher

An estuarine crocodile, also known as a “saltie”.

Many of the world’s 27 species of crocodylians will soon be either totally or locally extinct due to human population expansion and intensive land-use for agriculture depleting the water bodies, which provide succour to crocs, said a University of Queensland researcher.

Emeritus Professor Gordon Grigg of UQ says the fact that these reptiles had survived millions of years was no good owing to current rate of human expansion and encroachment of natural resources. “The current human population level and its magnitude and rate of resource consumption are unprecedented,” Professor Grigg said.

Only those crocs living in remote wetland habitats in which humans see no benefit may survive into the future, he said. Some crocodylians might have already become extinct if not for active conservation management undertaken in the second half of the 20th Century.

“For some species, the incentive for conserving them has been the commercial value of their hides, but that is dependent upon its use in high fashion garments and accessories, and that is a somewhat fragile foundation,” he said.

On flip side, the rising temperatures and sea levels may turn a more positive note for crocodylians, as it may create more habitat that will be suitable for any species to survive the human onslaught, he said wryly.

The largest living crocodiles, the estuarine or saltwater crocodile (Crocodylus porosus), are found in Northern Australia and can grow to six metres and weigh more than 900 kilograms.

Professor Grigg said estuarine crocodiles, also known as Indo-Pacific crocodiles or “salties”, were one of the luckier species because human populations across Australia’s north were unlikely to increase significantly in the next few decades.  They might be among the survivors.

Professor Grigg and illustrator and biologist David Kirshner, in their recent book, Biology and Evolution of Crocodylians, reviewed the biology of the crocodiles, alligators, caimans and gharials, and also discusses the great diversity of their gigantic extinct ancestors, some of which were probably warm-blooded.

Gaza May Become ‘Uninhabitable’ in 5 Years: UNCTAD

Living conditions in Gaza are so bad that they’ve been described as “less than human” and potentially uninhabitable by 2020, the UN has said sending out warning signals, which have emanated from the UN trade and development agency, UNCTAD, in its report into the Palestinian economy.

In addition to severe crises linked to water and electricity shortages, the UN agency says that Gaza’s 1.8 million residents have yet to recover from the destruction of last year’s conflict with Israel.

Three wars in six years and eight years of economic blockade have been blamed for terrible living conditions in the Territories Occupied by Israel, the UN trade and development agency (UNCTAD) said Tuesday.

In its latest report into Gaza and the West Bank, UNCTAD experts warn that development is not merely hindered, but reversed. In fact, the figures show that for the first time since 2006, the Palestinian economy has gone into recession.

The conflict in 2014 was particularly damaging, with whole areas of Gaza still flattened by attacks. So says UNCTAD’s Mahmoud Elkhafif.

“The fact that electricity is not enough, that a number of hospitals have been destroyed, the fact that there is no drinking water enough, it’s just what any rational human would (not) doubt what’s going to happen. I mean, we had had a study before the destruction of 2014 indicating that Gaza won’t be liveable in 2020, it’s not that things stayed as they were in 2020 but they got much, much worse in 2014.”

Israel is criticised for withholding almost USD $700 million of import tax revenue from the Palestinian authorities in the first four months of the year.

According to the UN agency it’s the sixth time Israel has withheld the monies since 1997, which are far and away the main source of public revenue in the West Bank and Gaza.

In another sign of the deteriorating conditions on the ground, UNCTAD said that in the year 2000, 72,000 people depended on food aid, but now that number has risen to almost a million. And in Gaza, unemployment is as high as 80 per cent, the UN agency said.

 

 

UN Seeks Humanitarian Intervention to Help Syrian Refugees

In the wake of the grim discovery of the bodies of more than 70 people inside a truck abandoned near Austria’s border with Hungary, UN Secretary-General Ban Ki-moon has urged the world to come together to provide comprehensive responses to migration issues, including tackling smugglers and resolving ongoing conflicts, among other root causes.

“I am horrified and heartbroken at the latest loss of lives of refugees and migrants in the Mediterranean and Europe, declared the Secretary-General following the discovery of the bodies in the abandoned vehicle, and upon hearing reports that many of the victims were Syrian asylum seekers – including children.

Meanwhile in Geneva, the Office of the UN High Commissioner for Refugees (UNHCR) spokesperson Melissa Fleming said, “this tragedy shows people smugglers have no regard for human life and are only after profit. It also underscores the desperation of people seeking protection or a new life in Europe.”

Austrian police say that they believe the truck came from Hungary and entered Austria on Wednesday night or early Thursday morning, and that the victims might have been dead for one or two days. Their identity is still unknown but it is presumed that they were being transported by smugglers.

After establishing that there were no survivors, the police closed the truck and moved it to another location for further investigations.

UNHCR expressed its hope that this incident will result in strong cooperation among European police forces, intelligence agencies and international organisations to crack down on the smuggling trade while putting in place measures to protect and care for victims.

Ms. Fleming reiterated UNHCR’s call to European countries to approach the refugee crisis “in a spirit of solidarity and cooperation and to provide those seeking safety in Europe with safe legal alternatives – including resettlement or humanitarian admission programmes, flexible visa policies and family reunification – to dangerous irregular voyages.”

Every day last week, the Hungarian border police intercepted more than 2,000 people crossing the border from Serbia. On Wednesday, police reported 3,241 new arrivals, including 700 children – the highest number in a single day so far this year.

Syrian refugees constitute the majority of the asylum-seekers, many of whom are women and children. They travel in large groups of over 200 – walking along rail tracks or crawling under barbed wire – as work continues on a 175 kilometres long wall at the Hungarian-Serbian border.

 

With a maximum capacity of 5,000 people, Hungary’s four reception centres are overcrowded, causing long waits and further exacerbating asylum-seekers’ angst. The Hungarian police do not have social workers or enough interpreters in Arabic, Dari, Pashto and Urdu, which makes communication difficult.

According to the latest official statistics, so far this year more than 140,000 people have sought asylum in Hungary, compared to 42,000 people last year. Most of those lodging asylum applications are from Syria, Afghanistan, Iraq and Pakistan, and they include some 7,000 unaccompanied children.

As the “heart-breaking” image of a drowned refugee boy who washed up on a beach in Turkey ricocheted around the world on social media, along with equally painful images of children lying suffocated in the backs of trucks crossing borders and being passed over barbed wire fences by desperate parents, Anthony Lake, Executive Director of the United Nations Children’s Fund (UNICEF) today made a powerful plea for action to protect migrant and refugee children.

“It is not enough for the world to be shocked by these images. Shock must be matched by action,” declared the UNICEF chief.

In a statement issued by the agency, Mr. Lake advocated that all decisions regarding the child migrant and refugee crisis in Europe be guided by the best interests of the children involved, and that measures be taken to ensure they receive adequate health care, food, emotional support, education, shelter and protection.

UNICEF estimates that at least a quarter of the hundreds of thousands of people who have sought refuge in Europe are children, many of whom have fled the conflict in Syria.

Some 2,500 people have died or gone missing this year while attempting the crossing to Europe.

“Our hearts go out today to the families who have lost children – off the coasts, on the shores, and along the roadsides of Europe,” said Lake. “As the debates on policies proceed, we must never lose sight of the deeply human nature of this crisis. Nor of its scale,” he added.

“And we should never forget what lies behind so many of the stories of families seeking sanctuary in Europe: terrible conflicts such as that in Syria, which already has forced some 2 million children to flee their country. Only an end to these conflicts can bring an end to the misery of so many.”

Muhammad Yunus Opens Narayana Hridayalaya Hospital in Mysore

Nobel laureate and microfinance pioneer Mohammad Yunus, who was in Mysore to open a 200-bed multi-specialty hospital for the working class on Friday, said the need for social entepreneurship is the new call of the day.

The 200-bed Narayana Hrudayalaya will have only general wards and taking cue from Yunus, NH founders have set up a hospital simple and pro-poor in ambience.

“I had heard about the revolution Yunus had created when I was working in Kolkata,” said Dr Devi Shetty, founder of Narayana Health. To make poor people who get scared when they go to corporate hospitals and instead squat on the floor, the new hospital will be friendly for all, insisted Dr Shetty.

Muhammad Yunus at a special summit hosted by the University of Salford.

Known for his innovative pro-poor model of empowering women in 1976, Dr Yunus, an economic professor, founded Bangladesh’s Grameen Bank and went on to win Nobel Peace Prize in 2006. The first microfinance lending bank has benefitted more than 8.5 million women.

When women in his country got into microfinancing, it changed women’s marriage equation too, he said. “When I started the bank, I was clear that 50% of our borrowers must be women. Now rural women have money and their husbands borrow from them,” he told TOI in an interview.

“Money means power. It has given them confidence. And has helped them in their children’s education. Worldwide wherever I go, I see young doctors and engineers who tell me that they hail from the villages of Bangladesh and were assisted by Grameen Bank. That gives me immense satisfaction,” said Yunus.

His advice amid increasing criticism against misadventure of microfinance model in Andhra Pradesh was to be a social entrepreneur. Business does not mean money-making, he reiterated.

“Dissociate selfishness. I delinked business from money-making. Social entrepreneurs can touch the lives of many. It’s not rocket science to create a business model,” Yunus said.

Missing Mobile Phone? Don’t Let it Take Over as Phobia!

Apple’s iPhone 6

Call it missing mobile phone phobia or nomophobia or just another day of anxiety when you miss your device at home or office.

Scientists from Iowa State University have identified four dimensions of the phobia after a survey conducted on participants, who responded on a scale of one (strongly disagree) to seven (strongly agree).

More to do with the fear of losing connectedness with friends and family or not being able to access information, the fear of remaining incommunicado even for few hours haunts majority of them.

Initially the researchers interviewed nine students and based on their responses, developed a questionnaire which was given to 301 students.

Research student Caglar Yildirim at the Iowa State University (ISU) and Ana-Paula Correia, an associate professor in ISU’s School of Education finally came out with a set of four dimensions to detect the most-prevalent modern-day phenomenon that is often taking the shape of phobia.

Based on the score, the researchers said the higher scores corresponded to greater nomophobia severity, and vice versa. The team findings have been published in the journal Computers in Human Behavior.

Here are the sample questions in the questionnaire:

— “I would feel uncomfortable without constant access to information through my smartphone”

— “I would be annoyed if I could not look information up on my smartphone when I wanted to do so”.

“Being unable to get the news on my smartphone would make me nervous” or
“I would be annoyed if I could not use my smartphone and/or its capabilities when I wanted to do so”.

— “Running out of battery in my smartphone would scare me”

— “If I were to run out of credits or hit my monthly data limit, I would panic” and
“If I did not have a data signal or could not connect to Wi-Fi, then I would constantly check to see if I had a signal or could find a Wi-Fi network”.

Here are some typical answers from the participants:

— “If I could not use my smartphone, I would be afraid of getting stranded somewhere”.

— “If I could not check my smartphone for a while, I would feel a desire to check it”.

To a question as to how they would react if they did not have their smartphone with them, they responded with statements like:

— “I would feel anxious because I could not instantly communicate with my family and/or friends”

— “I would feel nervous because I would not be able to receive text messages and calls.”

Karnataka Farmers’ Association Calls for Bandh Over Farmers’ Suicides

The sugarcane farmers’ associations in Karnataka have called for a bandh on Saturday, Sept. 5, 2015 which may see some key areas of northern and northwestern Karnataka closed, while Bangalore and southern Karnataka districts will remain unhit due to it.

While it is unlikely to hit normal life in Bangalore and across Karnataka, Bangalore Metropolitan Transport Corporation (BMTC) and Karnataka State Road Transport Corporation (KSRTC) officials said there will be no disruption in bus services tomorrow.

Otherwise, autos and taxis will run as usual in Bangalore. Many schools remain closed on Saturday but those on six-day a week schedule may opt to remain open, except in those districts where bandh will be forced upon them by activists.

All hospitals, medical shops will remain open.

The bandh was called by Karnataka State Sugarcane Growers’ Association (KSSGA) in protest against Karnataka government’s apathy to the rising farmer suicides in the state.

KSSGA president Kurubur Shanthakumar said the state-wide bandh was the culmination of one-month old strike going on in the state by farmers. “In order to put pressure on the authorities, the association will observe a bandh and also be part of the agitation till the demand is met,” he told the New Indian Express.

The farmers’ demands include waiving off of crop loans from nationalised and cooperative banks as the drought situation in the state has adversely affected agricultural production. The farmers are also demanding a Vidarbha-like Package of Rs.10,000 crore for Karnataka.

Other demands include compensation of families of farmers who committed suicide to the extent to Rs. 10 lakh, raising issue price of sugarcane, implement the Kalasa-Banduri Nala project, that was stalled in 2002 due to objections raised by Goa. The project was to provide drinking water to Belgaum, Dharwad and Gadag districts.

Apart from Sept. 5 bandh, the KSSGA also plans to hold a rally in Bangalore on September 7 and also stage a dharna in front of the Chief Minister’s residence. While no political parties were allowed to attend their protest, Shanthakumar said, Karnataka State Cricket Association (KSCA) has extended its support to the protest.

India Internet Users Now More Than US Population Put Together

India’s current Internet users have crossed 352 million with the liberal addition of 52 million in the first half of 2015 by IAMAI, whose report is apparently based on estimates and not on empirical data.

Otherwise, the number is overwhelming as it is more than the entire population of the US put together. As of 2014, the US population was 319 million.

The mobile and Internet research body said in its January release that its estimates show mobile users by June 2015 would reach 213 million and now that the first half of the year is over, the sequel release has put forward the exact figure of 213 million, without explaining the methodology.

In January, IAMAI said, “The number of mobile internet users in India is expected to reach 213 million by June 2015.” In August, IAMAI  report listed the same figure of 213 million, raising eye-brows as to how the exact figure was reached.

On the sideslines of the report, the Internet and Mobile Association of India (IAMAI) said it took more than 10 years to move from 10 million to 100 million in India but now the time period has shrunk to just 3 years to jump from 100 to 200 million.

Afterwards, in just one year, the number rose to 300 million, thanks to mobile phone users increasig in number rapidly, said a release by IAMAI.

Life Expectancy: Indian women live longer than men

Life expectancy has escalated to a great extent since 1990 as people even in poor nations are living longer than ever, though many of them struggling with sickness and age-old ailments, finds a new study.

In India, between 1990 and 2013, life expectancy for men and women has elevated by 6.9 years and 10.3 years, respectively.

This new study was conducted in 188 countries by an international research team working on a project called “Global Burden of Disease” and headed by Institute for Health Metrics and Evaluation (IHME) at the University of Washington.

Owing to the deterioration of mortality and illness rates due to HIV/AIDS and malaria in the last ten years, health has enhanced to a great deal across the globe. Apart from this, meeting contagious, maternal, newborn and nutritive conditions, effectively has also added to the enhancement.

Nevertheless, healthy life expectancy (HALE) at birth hasn’t seen much improvement, thus; making those who live longer live sicker.

Theo Vos, the professor of IHME as well as who lead the study said albeit health has seen a global advancement it’s time that “more effective ways” to treat and combat disorders and diseases are discovered.

The study discovered that global life expectancy and healthy life expectancy for both genders escalated by 6.2 years and 5.4 years, respectively. However, in comparison to the life expectancy that increased from 65.3 in 1990 to 71.5 in 2013, healthy life expectancy didn’t see a drastic leap with 56.9 in 1990 to 62.3 in 2013.

Majority of the evaluated nations showed “significant and positive” healthy life expectancy changes. However, Belize, Botswana and Syria didn’t show drastic changes in HALE in 2013 as compared to 1990 with the first two nations, showing regression of 2 and 1.3 years, respectively.

In other cases, countries like Paraguay, Belarus and South Africa saw a deterioration in healthy life expectancy. For instance, places like Swaziland and Lesotho in Africa and South Africa, respectively, saw healthy life expectancy drop in individuals born in 2013 as compared to them who were born 20 years before.

People of Cambodia and Nicaragua showed gripping escalation between 1990 and 2013 with 13.9 and 14.7 years, respectively.

Nonetheless, Ethiopia was pin-pointed as one of the nations that have been giving massive efforts to make sure that their country people live both healthier and longer. For instance, in 1990, the healthy life expectancy of an Ethiopian was 40.8 years, but by 2013 with 13.5 years leap, it saw over a two-fold increase to 54.3 years.

Christopher Murray, who is the IHME director said albeit “income and education” play important roles in ensuring proper health, it doesn’t “tell the full story,” adding that weighing both healthy life expectancy and health loss on each sides at country level will facilitate “guide policies” in ensuring longer and healthier lives in every nook and cranny of the world.

Italy, Spain, Norway, Switzerland and Israel showed the lowest rates of health loss. With 42 years, in 2013, Lesotho recorded the lowest healthy life expectancy whereas with 73.4 years, Japan recorded the highest healthy life expectancy.

The findings have been published in the August 27 issue of the journal “The Lancet”.

According to the World Health Organization (WHO), Europe showed stagnation in showing better life expectancy during the 1990s, but after 1990 when life expectancy increased by 6 years around the world, Europe also saw some increase.

On the other hand, African nations have been showing a drop in life expectancy due to being plagued by HIV/AIDS, but now with the accessibility of antiretroviral therapy, the rates have seen an escalation. For instance, in 2000, standard life expectancy at birth was 50 years, but it saw an 8 year leap in 2013.

WHO further informed that high-income nations showed greater life expectancy at 60 years of age with expectation of the individual, living another 23 years in comparison to low-income and lower-middle income nations, which showed 17 more years of life expectancy.

India Ready with ‘Comprehensive’ Plan on INDCs Ahead of Paris Meet: Javadekar

Frank Noronha are also seen. (PIB Photo).

India’s environment minister Prakash Javadekar has reiterated India’s stand on compliance with the Climate Change agreements in the past and to forge ahead with its comprehensive plan at the Paris Summit to be held in December this year.

The minsiter said India is finalizing its draft proposal before the crucial UN climate change conference in Paris and unlike most other countries whose ‘Intended Nationally Determined Contributions’ (INDCs) reflect only mitigation measures, India will have two different templates — one for adaptation and the other for mitigation apart from technology and capacity build up, Javadekar said.

Wrapping up an 8-month effort, the minister said “We are at an advanced stage of preparing our INDC… We have been engaged in this exercise and widest consultations have taken place with all ministries, state governments, research institutes, industry, think tanks and many organisations.”

Javadekar said all elements will be part of India’s INDCs, including efforts for mitigation, adaptation, finance, technology and capacity building, he said preparing for the final draft. He said India’s INDCs reflect the mandate of United Nations Framework Convention on Climate Change (UNFCCC).

However, India is still a latecomer in terms of submission of its INDCs as the US, China and the European Union countries have already submitted their INDCs. Some of the projects undertaken by the ministry of forests and environment will figure in the INDCs, it is learnt.

But India has made it evident in all global gatherings that “Developed world would now have to walk the talk and will have to provide green climate fund to the developing world.”

Being a developing nation, India has maintained its “Common but Differentiated Responsibility” approach to global climate change and sought the developed world to pay the developing world or poorer nations like India and defer the carbon tax model for some more time.

The UN has been insisting on a “realistic” trajectory to mobilize $100 billion per year by 2020 that was pledged by developed countries in 2009 – with resources above and beyond official development assistance (ODA).

The UN Green Climate Fund has remained a lukewarm effort without funds.

Sensex Crashes by 1100 Points

While the market is going agogue over the sudden crash of Sensex by 1100 point in intra-day trading on Monday, eroding about Rs.4 lakh crore from the pockets of shareholders, there is one reason for optimists to smile.  BUY now!

Many TV show experts are suggesting the move to buy but foreign investors are driven by the ripple effect created by Yuan’s unrealistic devaluation that has all the potential to kick off another Asian Currency Crisis of the mid-1990s.

The ripple effect is seen in virtual shock and apathy in the trading session in the morning to make any trade decisions by buyers and brokers alike and even the Indian rupee hit a highest low of Rs.66.50, which is lowest since September 2013.

Monday’s market crash was the biggest after 2008 recession, as on October 24, 2008, it recorded a low of 1204.88 points. But Monday crash is different as it stems directly from the Yuan’s devaluation.

Speculations are high that the 2008 recession was driven by the US downturn while the 2015 would be the Year of China, with its extreme global reach. Another reason could be to bring the markets heed the global opinion on China’s political overtures, especially aimed at Japan.

Japan Prime Minister Shinzo Abe on Monday cancelled his state visit to China and the political fallout could be a trigger to anti-China sentiments bringing down Asian markets for now. The long-term impact will be known only in a couple of months when markets continue to be volatile.

While the Indian market reacted cautiously last week when China announced one of its worst devaluation of Yuan, the possible market reaction in India on the opening day of the week is abrupt and unexplainable.

The slowdown of the Chinese economy may recover from its devaluation but it is strange to see the Indian market reacting similarly as devaluation of the Indian rupee on par with its Chines counterpart is unadvisable for the long term market stabilization.

However, the market needed to correct itself from the buoyant artificial picture being projected by the industry in India following the BJP win last year. Though the Modi government is known for its pro-business and pro-industry policies, the undue delay in passage of bills and the bedlam in parliament have had enough reasons not to cheer about for the industry.

In fact, Indian recovery map was not as great as China or the US since 2008 crash as its macro economic indicators like current account deficit and forex reserves remained same, said Nirmal Jain, Chairman and Managing Director IIFL in a TV show on CNBC-TV18.

Another reason for the abrupt fall is that FIIs or foreign investors are quick to withdraw their investments in India after the Chinese market went down over the Yuan devaluation. Unless Indian investors repose their faith in the markets, Sensex is unlikely to stabilize in the next few days, but experts have advised buying for their clients now.

Meanwhile, European markets have responded taking the curve down as of now and in few hours when the US West Coast opens its stock exchanges, the bells will ring in the effect at least initially.

Imagine World Map Without Humans, Here It Is!

An interesting study by Arhus University in Spain has come out with a world map sans humans and how it would have shaped the animal world on Earth, if man had not appeared about 100,000 years ago.

 

The fact that the greatest diversity of large mammals is found in Africa reflects past human activities – and not climatic or other environmental constraints. This is determined in a new study, which presents what the world map of mammals would look like if modern man (Homo sapiens) had never existed.

In a world without humans, most of northern Europe would probably now be home to not only wolves, Eurasian elk (moose) and bears, but also animals such as elephants and rhinoceroses.

This is demonstrated in a new study conducted by researchers from Aarhus University, Denmark. In a previous analysis, they have shown that the mass extinction of large mammals during the Last Ice Age and in subsequent millennia (the late-Quaternary megafauna extinction) is largely explainable from the expansion of modern man (Homo sapiens) across the world.

In this follow-up study, they investigate what the natural worldwide diversity patterns of mammals would be like in the absence of past and present human impacts, based on estimates of the natural distribution of each species according to its ecology, biogeography and the current natural environmental template. They provide the first estimate of how the mammal diversity world map would have appeared without the impact of modern man.

“Northern Europe is far from the only place in which humans have reduced the diversity of mammals – it’s a worldwide phenomenon. And, in most places, there’s a very large deficit in mammal diversity relative to what it would naturally have been”, says Professor Jens-Christian Svenning, Department of Bioscience, Aarhus University, who is one of the researchers behind the study.

Demand for Coffee Can Create Rift with Poorer Nations: Study

The explosion in worldwide coffee consumption in the past two decades has generally not benefitted farmers of coffee beans in poorer nations along the equator, said a new study.

A University of Kansas (KU) researcher studying trade and globalization has found that the shift to “technified” coffee production in the 1970s and 1980s has created harsher economic and ecological consequences for heavy coffee-producing nations, such as Honduras, Colombia, Guatemala, Brazil, Vietnam and Ethiopia.

“Historically, coffee has been exploited by the West in various ways, because it’s consumed in rich countries, and grown in poor ones,” said Alexander Myers, a KU doctoral candidate in sociology.

Myers will present his study, “Trading in Crisis: Coffee, Ecological Rift, and Ecologically Unequal Exchange,” at the 110th Annual Meeting of the American Sociological Association (ASA). The paper examines how the shift to technified coffee for mass production and to meet greater demand hurt peasant farmers of those countries and had a major ecological influence there, especially with the amount of water required for the crops.

Myers said the shift to technified coffee production changed the process to look more like traditional large wheat or soybean farms in the United States as opposed to allowing coffee plants to grow in smaller shaded areas. The latter process used much less water, for example, and it allowed farmers to diversify their crops and use their land to plant other crops as well.

Technified production requires farmers to exclusively grow coffee.”Especially these peasant farmers who maybe have a small plot of land, they rely almost exclusively on coffee sales to sustain themselves,” Myers said.

Major drops in commodities prices of coffee beans to around $0.50 per pound in 2001 nearly wiped out economies of those nations, for example.”That really hit the famers hard, and it caused a lot of these family farms that have historically relied on coffee to keep themselves afloat,” Myers said.

The technification of coffee production also required a new type of coffee bean to grow effectively, but the process also required much more water to produce. Some ecological researchers have estimated the average cup of coffee takes 140 liters of water to grow.”It’s very taxing environmentally,” Myers said.

The fair trade movement in the past two decades has helped to offset somewhat both the economic and ecological changes, especially for poorer farmers in developing countries. Myers said such movements could help raise awareness especially among coffee drinkers in Western nations.

“What we do matters. The choices that we make, the products that we buy have an impact on somebody,” he said. “Sometimes it’s a good impact. Sometimes it’s negligible or negative. But they do have impacts, so just trying to keep that in mind is important, especially in researching what is behind these consumption choices.”

Antarctic Detector Confirms Cosmic Neutrino Sighting

Researchers using the IceCube Neutrino Observatory have sorted through the billions of subatomic particles that zip through its frozen cubic-kilometer-sized detector each year to gather powerful new evidence in support of 2013 observations confirming the existence of cosmic neutrinos.

In the new study, the detection of 21 ultra high-energy muons — secondary particles created on the very rare occasions when neutrinos interact with other particles –provides independent confirmation of astrophysical neutrinos from our galaxy as well as cosmic neutrinos from sources outside the Milky Way.

The observations were reported in the journalPhysical Review Letters by the IceCube Collaboration, which called the data an “unequivocal signal” for astrophysical neutrinos, ultra high-energy particles that have traversed space unimpeded by stars, planets, galaxies, magnetic fields or clouds of interstellar dust — phenomena that, at very high energies, significantly attenuate more mundane particles like photons.

Because they have almost no mass and no electric charge, neutrinos can be very hard to detect and are only observed indirectly when they collide with other particles to create muons, telltale secondary particles.

The IceCube Collaboration, a large international consortium headquartered at the University of Wisconsin-Madison, has taken on the huge challenge of sifting through a mass of observations to identify perhaps a few dozen of the highest-energy neutrinos that have traveled from sources in the Milky Way and beyond our galaxy.

 

“Looking for muon neutrinos reaching the detector through the Earth is the way IceCube was supposed to do neutrino astronomy and it has delivered,” explains Francis Halzen, a UW-Madison professor of physics and the principal investigator of IceCube. “This is as close to independent confirmation as one can get with a unique instrument.”

Between May 2010 and May 2012, IceCube recorded more than 35,000 neutrinos. However, only about 20 of those neutrino events were clocked at energy levels indicative of astrophysical or cosmic sources.

 

But while the new observations confirm the existence of astrophysical neutrinos and the means to detect them using the IceCube Observatory, actual point sources of high-energy neutrinos remain to be identified.

Albrecht Karle, a UW-Madison professor of physics and a senior author of the Physical Review Letters report, notes that while the neutrino-induced tracks recorded by the IceCube detector have a good pointing resolution, within less than a degree, the IceCube team has not observed a significant number of neutrinos emanating from any single source.

 

IceCube is based at the Wisconsin IceCube Particle Astrophysics Center (WIPAC) at UW-Madison. The observatory was built with major support from the National Science Foundation as well as support from partner funding agencies worldwide. More than 300 physicists and engineers from the United States, Germany, Sweden, Belgium, Switzerland, Japan, Canada, New Zealand, Australia, the United Kingdom, Korea and Denmark are involved in the project.

India Seeks to Block Onion Exports, Increase Imports to Control Price

With the onion prices skyrocketing, the Indian government has cracked whip on rising prices of onions in the country going for a faster track imports and a tender has been floated for 10,000 MT of Onions which will be opened on 27th August, 2015. Currently, the onion prices are in the range of Rs. 80 (US$1.2) per kilogram.

To offset the exports, the Minimum Export Price of Onions has been increased further to US$ 700 per metric ton, from US$ 425 per MT announced in June. Earlier, it was only $ 245 per MT.

Besides, the Secretary (Consumer Affairs) on 24th August, 2015 met with SFAC, NAFED, MMTC, Department of Commerce, Ministry of Agriculture and Govt. of Delhi to review the action taken to keep the prices of onions in check.

To intervene in the market, Small Farmers Agribusiness Consortium (SFAC) and NAFED have procured 5857 MT of onions funded out of Price Stabilisation Fund meant to keep prices of essential commodities under control. SFAC has also procured 2511 MT of Onions for the Delhi Govt., making a total stock of 8368 MT of Onions.

In turn, SFAC is supplying Onions at Rs.30.50 per kg. to SAFAL, which is retailing at Rs.39 per kg. in Delhi. SFAC is also selling Onions to consumers at Rs.35 per kg. through 120 milk booths of DMS. A decision was also taken by Govt. of Delhi to sell Onions at subsidized rate of Rs.40 per kg. through 280 Fair Price Shops, which was further reduced to Rs.30 per kg. w.e.f. 12.8.2015

Prices of Onions have been rising on account of a decline in total production from 189.23 lakh tonnes in 2014-15 as against 194.02 lakh tonnes in 2013-14, a decrease of 4.79 lakh tonnes. The shortage has been attributed to adverse weather conditions including unseasonal rains in Maharashtra and Karnataka regions.

In a National Consultation Meeting held recently, it has been decided to keep prices of essential commodities, especially Onions under control. It also recommended effective action against hoarding and blackmarketing to control prices of food items. Chief Secretaries of States / UTs are also being reminded regularly to keep a watch on price rise and take effective action, said the government.

Union Government made an amendment of EC Act, 1955 on 1st July, 2015 to enable State Govt./UTs to impose stock limits on Onions for a further period of one year till 2nd July, 2016, said a statement.

Why OROP Issue Was a Pre-poll Harakiri by BJP?

Modi promised to implement OROP in his 2nd Independence Day speech but war veterans are not ready to quit hunger strike. (PIB)

The One Rank One Pension (OROP) scheme that was hanging on the Finance Ministry for over five years, both the Congress-led UPA government and the BJP-led NDA government under Narendra Modi should own the responsibility for perpetuating it despite full knowledge that it was beyond mere political calculations involving a huge dent on the exchequer.

While the Congress relented just before the election year to benefit from the votes of these 30 lakh beneficiaries, BJP weaned them away promising its immediate implementation. Once in power, the staggering amount of Rs.8500 crore has forced Finance Minister Arun Jaitley to postpone the OROP beyond the second budget, forcing the ex-servicemen to hit the streets and now end up at the Jantar Mantar in hinger strikes.

For those new to the subject, implentation of OROP entails uniform pension benefits for the defence persons who retired in the same rank with the same service term, irrespective of their date of retirement. Current policy entails only those who retired after 1996 to draw more pension than those who retired before, though rank is the same.

With OROP, 22 lakh ex-servicemen and about 6 lakh war widows will get Rs.10,000 more on average. This has become imminent because the current policy entails those who retired after 1996 to draw more pension than those who retired before, though rank is the same.

“Modi has assured us that it will be implemented, but it has been one year,” said retired Colonel Anil Kaul, who is the media adviser to Indian Ex-Servicemen Movement (IESM) that is sprearheading the protest in New Delhi at Jantar Mantar. “The Prime Minister’s voice still echoes in our minds when he roared at the ex-servicemen rally on September 15, 2013, in Rewari and demanded a white paper on OROP from the UPA Government,” said ISEM earlier.

Now that the relay hunger strike entered 65 days, many war veterans who were in the forefront to die for the country are openly preparing themselves to die for the OROP implementation. Strange but no country would have upset its ex-servicemen given a chance.

In case of the Modi’s government too the question is bigger than mere rhetorics. Pumping in Rs.8,500 crore even if it is in incremental way, would mean a huge burden diverting funds from the developmental plans. Secondly, OROP would also undercut the cost of military expenditure on armaments but shows bigger than any other nation in the short run.

Finally, the government has no choice but to implement it. The question is from where will the finance minister draw the funds?
