A new way to store thermal energy

In large parts of the developing world, people have abundant heat from the sun during the day, but most cooking takes place later in the evening when the sun is down, using fuel — such as wood, brush or dung — that is collected with significant time and effort. Now, a new chemical composite developed by researchers at MIT could ...

Making mosquitoes self-destruct

Researchers at the University of California, Riverside have developed transgenic mosquitoes that stably express the Cas9 enzyme in their germline. The addition of Cas9 will enable the use of the CRISPR gene editing tool to make efficient, targeted changes to the mosquitoes’ DNA. As proof of concept, the researchers used the system to disrupt cuticle, wing, and eye development, producing ...

Improving clinical trials with machine learning

Machine learning could improve our ability to determine whether a new drug works in the brain, potentially enabling researchers to detect drug effects that would be missed entirely by conventional statistical tests, finds a new UCL study published in Brain. “Current statistical models are too simple. They fail to capture complex biological variations across people, discarding them as mere noise. ...

Making big data a little smaller

When we think about digital information, we often think about size. A daily email newsletter, for example, may be 75 to 100 kilobytes in size. But data also has dimensions, based on the numbers of variables in a piece of data. An email, for example, can be viewed as a high-dimensional vector where there’s one coordinate for each word in ...

Computer scientists address gap in messaging privacy

Researchers have developed a solution to a longstanding problem in the field of end-to-end encryption, a technique that ensures that only sender and recipient can read a message. With current end-to-end encryption, if an attacker compromises a recipient’s device, they can then put themselves in a position to intercept, read and alter all future communications without sender or recipient ever ...

Goodbye, login. Hello, heart scan

Forget fingerprint computer identification or retinal scanning. A University at Buffalo-led team has developed a computer security system using the dimensions of your heart as your identifier. The system uses low-level Doppler radar to measure your heart, and then continually monitors your heart to make sure no one else has stepped in to run your computer. The technology is described ...

Is the Earth warming? The ocean gives you the answer

Humans have released carbon dioxide and other greenhouse gases, and the result is an accumulation of heat in the Earth’s climate system, commonly referred to as “global warming”. “How fast is the Earth’s warming?” is a key question for decision makers, scientists and general public. Previously, the global mean surface temperature has been widely used as a key metric of ...

A ‘virtual heart’ to simulate arrhythmia

A group of researchers from MIPT and Ghent University (Belgium) has developed the first realistic model able to reproduce the complexity of the cardiac microstructure. The researchers hope that the model will help them better understand the causes of fibrosis which affects the onset of cardiac arrhythmias. Although the model is currently only able to simulate one layer of cardiac ...

Fast magnetic writing of data

For almost seventy years now, magnetic tapes and hard disks have been used for data storage in computers. In spite of many new technologies that have been developed in the meantime, the controlled magnetization of a data storage medium remains the first choice for archiving information because of its longevity and low price. As a means of realizing random access ...

New software can detect when people text and drive

Computer algorithms developed by engineering researchers at the University of Waterloo can accurately determine when drivers are texting or engaged in other distracting activities. The system uses cameras and artificial intelligence (AI) to detect hand movements that deviate from normal driving behaviour and grades or classifies them in terms of possible safety threats. Fakhri Karray, an electrical and computer engineering ...

Face value

Scientists have long deemed the ability to recognize faces innate for people and other primates — something our brains just know how to do immediately from birth. However, the findings of a new Harvard Medical School study published Sept. 4 in the journal Nature Neuroscience cast doubt on this longstanding view. Working with macaques temporarily deprived of seeing faces while ...

Recipe for safer batteries — Just add diamonds

While lithium-ion batteries, widely used in mobile devices from cell phones to laptops, have one of the longest lifespans of commercial batteries today, they also have been behind a number of recent meltdowns and fires due to short-circuiting in mobile devices. In hopes of preventing more of these hazardous malfunctions researchers at Drexel University have developed a recipe that can ...

Drones relay RFID signals for inventory control

Radio frequency ID tags were supposed to revolutionize supply chain management. The dirt-cheap, battery-free tags, which receive power wirelessly from scanners and then broadcast identifying numbers, enable warehouse managers to log inventory much more efficiently than they could by reading box numbers and recording them manually. But the scale of modern retail operations makes even radio frequency ID (RFID) scanning ...

A more complete picture of the nano world

They may be tiny and invisible, says Xiaoji Xu, but the aerosol particles suspended in gases play a role in cloud formation and environmental pollution and can be detrimental to human health. Aerosol particles, which are found in haze, dust and vehicle exhaust, measure in the microns. One micron is one-millionth of a meter; a thin human hair is about ...

Turning human waste into plastic, nutrients could aid long-distance space travel

Imagine you’re on your way to Mars, and you lose a crucial tool during a spacewalk. Not to worry, you’ll simply re-enter your spacecraft and use some microorganisms to convert your urine and exhaled carbon dioxide (CO2) into chemicals to make a new one. That’s one of the ultimate goals of scientists who are developing ways to make long space ...

Picture perfect

When taking a picture, a photographer must typically commit to a composition that cannot be changed after the shutter is released. For example, when using a wide-angle lens to capture a subject in front of an appealing background, it is difficult to include the entire background and still have the subject be large enough in the frame. Positioning the subject ...
