A new — and reversible — cause of aging

NAD, a naturally produced compound in cells, rewinds aspects of age-related demise in mice
December 20, 2013

Researchers have discovered a cause of aging in mammals that may be reversible: a series of molecular events that enable communication inside cells between the nucleus and mitochondria.

As communication breaks down, aging accelerates. By administering a molecule naturally produced by the human body, scientists restored the communication network in older mice. Subsequent tissue samples showed key biological hallmarks that were comparable to those of much younger animals.… read more

Shapeways, a Netherlands-based online 3D printing company, has opened a “factory of the future” in Queens, New York that plans to house 50 high-resolution industrial 3D printers and print custom-designed products a year, Popular Science reports.

The company will allow customers to upload custom 3D designs, and then prints them using materials including acrylic, nylon, glass, gypsum, ceramic, and sandstone, and precious metals such as silver, and ships the… read more

Email services close and destroy data rather than reveal files

1984-Big-Brother

Lavabit, a Texas-based service that was reportedly used by Edward J. Snowden, announced the suspension of its service Thursday afternoon to avoid being “complicit in crimes against the American people,” The New York Times reports.

Within hours, a fast-growing Maryland-based start-up called Silent Circle also closed its e-mail service and destroyed its e-mail servers.

In effect, both businesses destroyed their assets — in part or in… read more

Vicarious AI breaks CAPTCHA ‘Turing test’

October 28, 2013

CAPTCHA - featured

Vicarious, a startup developing artificial intelligence software, today announced that its algorithms can now reliably solve modern CAPTCHAs (Completely Automated Public Turing tests to tell Computers and Humans Apart).

Stanford University researchers have suggested that a CAPTCHA scheme (which are used by websites to verify that a visitor is human by asking them to transcribe a string of distorted letters) should be considered “broken” if an algorithm… read more

Discovery of quantum vibrations in microtubules inside brain neurons corroborates controversial 20-year-old theory of consciousness

A review and update of a controversial 20-year-old theory of consciousness published in  Elsevier’s Physics of Life Reviews (open access) claims that consciousness derives from deeper-level, finer-scale activities inside brain neurons.

The recent discovery of quantum vibrations in microtubules inside brain neurons corroborates this theory, according to review authors Stuart Hameroff and Sir Roger Penrose. They suggest that EEG rhythms (brain waves) also derive from deeper level… read more

Can DARPA spark a DIY brain-scanning movement?

A working prototype of a low-cost electroencephalography device funded by the US Defense Advanced Research Projects Agency (DARPA) made its debut in New York this weekend, the first step in the agency’s effort to jumpstart a do-it-yourself revolution in neuroscience, The Verge reports.

Dr. Bill Casebeer, a DARPA program manager, is hoping to spark a neuroscience fad within the maker movement. His goal is to return to… read more

A comet called C/2013 A1 (Siding Spring) is expected to miss Mars around Oct. 19, 2014 by 37,000 km (23,000 miles), says Bad Astronomy Slate blogger Phil Plait.

Assuming it does hit, while the nucleus size is not well known, it may be as small as 15 kilometers (9 miles) or as big as 50 km (30 miles). Even using the small number means Mars would… read more

Portions of Albert Einstein’s brain have been found to be unlike those of most people and could be related to his extraordinary cognitive abilities, according to a new study led by Florida State University evolutionary anthropologist Dean Falk.

Falk and colleagues examined the entire cerebral cortex of Einstein’s brain based on 14 recently discovered photographs. The researchers compared Einstein’s brain to 85 “normal” human brains… read more

A theoretical, three-dimensional (3D) form of carbon that is metallic under ambient temperature and pressure has been discovered by an international research team.

The search for this form of carbon has remained an ongoing challenge for scientists in the field.

Researchers from Peking University, Virginia Commonwealth University and Shanghai Institute of Technical Physics employed state-of-the-art theoretical methods to show that it is possible to manipulate carbon… read more

Using deep learning, an AI technique inspired by theories about how the brain recognizes patterns, technology companies are reporting startling gains in fields as diverse as computer vision, speech recognition and the identification of promising new molecules for designing drugs, The New York Times reports.

The advances have led to widespread enthusiasm among researchers who design software to perform human activities like seeing, listening and thinking. They offer… read more

A cure for type 1 diabetes

Diabetic dog cured from the disease

Researchers at the Universitat Autònoma de Barcelona (UAB) have succeeded in completely curing type 1 diabetes in dogs with a single session of gene therapy by introducing a “glucose sensor” into muscle.

This is the first time the disease has been cured in large animals, a fundamental step towards applying the therapy in humans. The dogs recovered their health and no longer show symptoms of the… read more

NASA aims for human rendezvous at Mars in 2033

It would be the most precious cargo since the Apollo astronauts returned Moon rocks to Earth.

In 2033, humans would arrive in Mars orbit to pick up and return to Earth a small collection of Mars rocks that would have been previously collected and put into orbit.

An internal NASA study group, tasked with replanning the agency’s beleaguered Mars program, revealed onread more
