Untouched For The Last Billion Years, Water In Canadian Mine Holds Ingredients For Life

Scientists may have discovered the oldest free-flowing source of isolated water ever known.

Scientists digging around roughly one-and-a-half miles below the Earth’s surface in an Ontario mine may have just discovered the oldest free-flowing source of isolated, untouched water ever known. Though they don’t know if anything has been living in this water, it contains both methane and hydrogen—key ingredients for life—and has likely been isolated in rock down there, untouched by Earth’s atmosphere, for a staggering 1 billion years.

Physicists Show Time Flows Asymmetrically at the Electron Level

At the level of tiny particles, the laws of physics are symmetrical in time. A reaction that proceeds in one direction (such as particle A transforming into particle B) is just as likely to occur in the reverse direction (particle B transforming into A).

It’s not too strange a concept: A video showing a billiard ball’s initial bounce off a pool table’s cushion would look the same whether it was running backward or forward in time. The physics works just as well, and identically, either way.

Yet experiments since the 1960s have suggested there should be exceptions to this rule — special cases of so-called “time-reversal violation.” The first conclusive evidence of such a violation was finally discovered late last year by collaborators on an experiment named BaBar at Stanford University’s SLAC National Accelerator Laboratory.

Scientists Discover Protein That Reverses Heart Disease In Older Mice

Scientists at Harvard University think they have found a way to possibly reverse the aging process in human organs.

Dr. Richard Lee, director of regenerative medicine at Brigham and Women’s Hospital, and Amy Wagers, of the Department of Regenerative Biology at Harvard, made the discovery when they were working with younger and older mice.

They took an older mouse with the most common form of human heart failure and merged the mouse’s blood stream with that of a healthy young mouse using a Siamese twin technique known as parabiosis. They found that the older mouse’s diseased heart was able to reverse to a younger healthier condition. Read more

Orangutan From Borneo Photographed Using A Spear Tool To Fish

Specifically the orangutans were using sticks to pry open pulpy fruits that have “Plexiglas needles” capable of delivering a painful jab covering them. Using the tools, the orangutans were getting past handling the prickly husk and into the nutritious fruit. From an anthropological viewpoint, tool use represents an aspect of culture, since the entire group participates in a behavior that has developed over time. One unique thing to clarify is that only Sumatran orangutans have been observed to use tools, not orangutans from Borneo. Read more

Studies Discover Speed Of Light May Not Be Constant

SCIENTISTS may have to sharpen their pencils and re-do a lot of math: It seems the speed of light may not be constant after all.

In a finding that can potentially affect everything from the age of the universe to calculating the orbit of satellites, two new studies suggest  the speed of a photon in a vacuum may fluctuate by as much as 50 quintillionths of a second per square meter.

So, the speed of light – 299,792,458 meters per second – may need some rethinking. Read more

Russian Billionaire Plans To Make Humans Immortal By 2045

A Russian billionaire has unveiled plans to make humans immortal by converting them into ‘Terminator-style’ cyborgs – a creature that’s part human and part machine – within the next three decades.

Thirty two-year-old mogul, Dmitry Itskov has been pushing the project forward since 2011 when he founded the 2045 Initiative. His ultimate goal is to transfer a person’s mind or consciousness from a living brain into a machine with that its personality and memories intact, according to website Digital Trends.

The so called ‘Cyborg’ will have no physical form, and exist in a network similar to the Internet and be able to travel at the speed of light all over the Earth, or even into the space. Read more

Artificial wombs are a staple of science fiction, but could we really build one? As time passes, we’re inching closer and closer to the day when it will finally become possible to grow a baby entirely outside the human body. Here’s what we’ll need to do to pull it off. Read More

New Radiation Belt Around Earth Discovered By NASA’s Van Allen Space Probes

A ring of radiation previously unknown to science fleetingly surrounded Earth last year before being virtually annihilated by a powerful interplanetary shock wave, scientists say.

NASA’s twin Van Allen space probes, which are studying the Earth’s radiation belts, made the cosmic find. The surprising discovery — a new, albeit temporary, radiation belt around Earth — reveals how much remains unknown about outer space, even those regions closest to the planet, researchers added.

Science Can Now Create Telepathic Rats

In the novel Childhood’s End, sci-fi writer Arthur C. Clarke tells the story of an alien civilization that visits Earth and helps to create a generation of telepathic human children. Mentally interconnected, the children think and act as one all-knowing organism.

Neuroscientist Miguel Nicolelis foresees a day when our brains really will be interconnected in what he calls a brain-net, and we won’t even need aliens to achieve it. In his lab at Duke University, Nicolelis has taken the first steps toward bringing brain-to-brain communication into reality by electronically connecting rats’ brains. The results are published in today’s issue of Scientific Reports.
