Spacex Founder Elon Musk’s BFR Mega Plan Not Practical in 50 Years

Speaking at the International Astronautical Congress in Adelaide, Australia, SpaceX founder Elon Musk revealed the hysteric side of his vision to transport passengers from New York to Shanghai in 39 minutes and sending humans to Mars in 2022 and not beyond as estimated. “Most of what people consider to be long-distance trips could be completed in less than half-an-hour,” Musk ...

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 ...

Dino-killing asteroid’s impact on bird evolution

Human activities could change the pace of evolution, similar to what occurred 66 million years ago when a giant asteroid wiped out the dinosaurs, leaving modern birds as their only descendants. That’s one conclusion drawn by the authors of a new study published in Systematic Biology. Cornell University Ph.D. candidate Jacob Berv and University of Bath Prize Fellow Daniel Field ...

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 ...

Noninvasive eye scan could detect key signs of Alzheimer’s years before patients show symptoms

Cedars-Sinai neuroscience investigators have found that Alzheimer’s disease affects the retina — the back of the eye — similarly to the way it affects the brain. The study also revealed that an investigational, noninvasive eye scan could detect the key signs of Alzheimer’s disease years before patients experience symptoms. Using a high-definition eye scan developed especially for the study, researchers ...

How future volcanic eruptions will impact Earth’s ozone layer

The next major volcanic eruption could kick-start chemical reactions that would seriously damage the planet’s already besieged ozone layer. The extent of damage to the ozone layer that results from a large, explosive eruption depends on complex atmospheric chemistry, including the levels of human-made emissions in the atmosphere. Using sophisticated chemical modeling, researchers from Harvard University and the University of ...

Supervolcanoes: A key to America’s electric future?

Most of the lithium used to make the lithium-ion batteries that power modern electronics comes from Australia and Chile. But Stanford scientists say there are large deposits in sources right here in America: supervolcanoes. In a study published today in Nature Communications, scientists detail a new method for locating lithium in supervolcanic lake deposits. The findings represent an important step ...

Oldest 8500-year-old Copper Smelting Unit Unearthed in Turkey

A team of archaeological scientists have found the earliest copper smelting event at the Late Neolithic site of Çatalhöyük in central Turkey, confirming the claim of the site’s archaeological importance. Whether metallurgy was such an exceptional skill to have only been invented once or repeatedly at different locations is therefore still contentious. The proponents of the latter have just provided ...

Attitudes on human genome editing vary, but reach consensus on holding talks

An international team of scientists announced they had successfully edited the DNA of human embryos. As people process the political, moral and regulatory issues of the technology — which nudges us closer to nonfiction than science fiction — researchers at the University of Wisconsin-Madison and Temple University show the time is now to involve the American public in discussions about ...
