Mayo Clinic study unmasks regulator of healthy life span

Promising target for aging disorders and cancer
December 20, 2012

A new series of studies in mouse models by Mayo Clinic researchers uncovered that the aging process is characterized by high rates of whole-chromosome losses and gains in various organs, including heart, muscle, kidney and eye, and demonstrate that reducing these rates slows age-related tissue deterioration and promotes a healthier life span.

“We’ve known for some time that reduced levels of BubR1 are a hallmark of aging… read more

Big news in the search for dark matter may be coming in about two weeks, the leader of a space-based particle physics experiment said Feb. 17 at the annual meeting of the American Association for the Advancement of Science, Space.com reports.

That’s when the first paper of results from the Alpha Magnetic Spectrometer, a particle collector mounted on the outside of the International Space Station,… read more

Carnegie Mellon computer searches web 24/7 to analyze images and teach itself common sense

NEIL program labels images, learns associations with minimal help from people

A computer program called the Never Ending Image Learner (NEIL) is now running 24 hours a day at Carnegie Mellon University, searching the Web for images, doing its best to understand them. And as it builds a growing visual database, it is gathering common sense on a massive scale.

NEIL leverages recent advances in computer vision that enable computer programs to identify and label objects in images,… read more

Why software’s wealthiest should fund experimental technologies

In the next few decades, we need more technology leaders to reach for some very big advances, says Nathan Myhrvold, a founder and vice chairman of TerraPower and former chief technology officer of Microsoft, writing in Technology Review.
If 20 of us were to try to solve energy problems — with carbon capture and storage, or perhaps some other crazy idea — maybe one or two… read more

The Inspiration Mars Foundation,  led by Dennis Tito, the first space tourist, will announce on Wednesday Feb. 27 a planned mission to Mars in 2018.

The mission would take advantage of a unique window of opportunity; the orbits of Earth and Mars will be closely aligned. The round-trip journey would start in January 2018 and take 501 days.

No details are available yet on how they… read more

Computer scientist Hava Siegelmann of the Biologically Inspired Neural & Dynamical Systems (BINDS) Laboratory at the University of Massachusetts Amherst, an expert in neural networks, has taken Alan Turing’s work to its next logical step.

She is translating her 1993 discovery of what she has dubbed “Super-Turing” computation into an adaptable computational system that learns and evolves, using input from the environment in a way much more like our… read more

Low-carbon technologies ‘no quick-fix,’ say researchers

February 16, 2012

Wind power

A drastic switch to low carbon-emitting technologies, such as wind and hydroelectric power, may not yield a reduction in global warming until the latter part of this century, research published today by the Institute of Physics suggests.

Furthermore, it states that technologies that offer only modest reductions in greenhouse gases, such as the use of natural gas and perhaps carbon capture and storage, cannot substantially reduce climate… read more

Lit Motors will shake up the electric vehicle market with its two-wheeled, untippable C-1

September 12, 2012

Imagine a vehicle that’s smaller than a Smart Car, nearly a third of the price of a Nissan Leaf ($32,500), safer than a motorcycle with a range capacity that just lets you drive and won’t ever tip over.

What you get is Lit Motors‘ C-1, the world’s first gyroscopically stabilized, two-wheeled all-electric vehicle, which launched at TechCrunch Disrupt in San Francisco today, writes Peter Ha on read more

Minnesota bans free online education, caves to Internet pressure

October 21, 2012

Minnesota’s Office of Higher Education was forced by public pressure Friday to cancel its bizarre bureaucratic decision to prohibit free online college courses offered through Coursera and other websites, Slate reported Friday.

India’s Tata Motors is pushing technology for compressed air to power cars forward with its project to build “Airpods zero-pollution, cute-as-a-bug smartcars that zip along at 40 m.p.h. via the magic of squeezed air, The Atlantic Cities reports.

They are built with pneumatic motors that use pressurized air to drive pistons.

The mid-sized model fits three passengers, although one must face backward.… read more

Evidence that photosynthesis efficiency is based on quantum mechanics

January 17, 2014

Light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics, according to the first unambiguous theoretical evidence of quantum effects in photosynthesis, published in the journal Nature Communications (open access).

The majority of light-gathering macromolecules are composed of chromophores (responsible for the color of molecules) attached to proteins, which carry out the first step of photosynthesis, capturing… read more

New evidence on how compound found in red wine can help prevent cancer

University of Leicester scientists have presented groundbreaking new evidence about how a chemical found in red wine can help prevent cancer.

Experts from around the world attended Resveratrol 2012, a major conference at the University to assess the latest advances in the study of resveratrol — a compound found in the skins of red grapes.

The conference featured new findings based on… read more

Most realistic android infant?

Affetto-internalmech2

Osaka University’s Asada Lab roboticists say Affetto is the most realistic infant robot ever made, thanks to the 12 degrees of freedom of its head, its smile, and the 20 flexible pneumatic actuators to move its arms, neck, and spine.

What do you think? Does this bypass the uncanny valley yet? (Warning: fast-forward to :58 to bypass the scary part.)… read more

Neuroscientists plant false memories in the brain

MIT study also pinpoints where the brain stores memory traces, both false and authentic
July 26, 2013

The phenomenon of false memory has been well-documented: In many court cases, defendants have been found guilty based on testimony from witnesses and victims who were sure of their recollections, but DNA evidence later overturned the conviction.

In a step toward understanding how these faulty memories arise, MIT neuroscientists have shown that they can plant false memories in the brains of mice.

They also… read more
