The FDA has told 23andMe, Inc., the Google-backed DNA analysis company cofounded by Anne Wojcicki, to halt sales of its Saliva Collection Kit and Personal Genome Service (PGS).

In a letter, the FDA said the company was acting “without marketing clearance or approval in violation of the Federal Food, Drug and Cosmetic Act (the FD&C Act)….”

“Most of the intended uses for PGS listed on your… read more

A 3D-printed Moon base baked from lunar dust

March 20, 2013

sinterhab-moon-base-4

Space architects have unveiled a concept for a 3D-printed Moon base called SinterHab near the lunar south pole. Modules would be constructed from lunar dust by microwave sintering and contour crafting, built by a large NASA spider robot.

Unlike an earlier, more bulky concept using a mobile printing array of nozzles on a 6 meter frame to spray a binding solution (glue) onto… read more

Non-invasive brain-to-brain interface: links between two brains

Direct communication between the brains of human and rat .... or between humans
April 8, 2013

brainstorm

We reported last month how Duke University researchers remotely linked the brains of two rats. Now researchers from the U.S and South Korea have have taken it a step further: a non-invasive functional link between the brains of different species (human and rat) — a brain-to-brain interface (BBI).

Researchers at Brigham and Women’s Hospital and Harvard Medical School set up a system intended to allow a human to… read more

A bucket-full of this material can absorb all the oxygen in a room

The stored oxygen can be easily released again whenever and wherever needed

A new crystalline material absorbs 160 times more oxygen than in the air around you — only a spoonful bucket-full (10 liters) of it is enough to suck up all the oxygen in a room, according to its developer, Professor Christine McKenzie in the Department of Physics, Chemistry and Pharmacy at the University of Southern Denmark.

A few grains of this material might absorb enough oxygen from the… read more

Blue Brain project accurately predicts connections between neurons

In a landmark paper, published this week in PNAS (forthcoming), the EPFL’s Blue Brain Project (BBP) has identified key principles that determine synapse-scale connectivity by virtually reconstructing (in supercomputer) a cortical microcircuit and comparing it to a mammalian sample.

These principles now make it possible to predict the locations of synapses in the neocortex, the researchers say.

“This is a major breakthrough,… read more

Replacing a defective gene with a correct sequence to treat genetic disorders

April 10, 2014

NewsImage-GeneRepair

Using a new gene-editing system based on bacterial proteins, MIT researchers have cured mice of a rare liver disorder caused by a single genetic mutation.

The findings, described in the March 30 issue of Nature Biotechnology, offer the first evidence that this gene-editing technique, known as CRISPR, can reverse disease symptoms in living animals. CRISPR, which offers an easy way to snip out mutated DNA and replace it with… read more

The cosmological supercomputer

How the Bolshoi simulation evolves the universe all over again
October 3, 2012

cosmic_web

Most of the ordinary matter in the universe — the stuff that makes up all the atoms, stars, and galaxies astronomers can see — is invisible, either sprinkled throughout intergalactic space in tenuous forms that emit and absorb little light or else swaddled inside galaxies in murky clouds of dust and gas, Joel R. Primack writes in IEEE Spectrum.

When astronomers look out into the night… read more

Musk, others commit $1 billion to non-profit AI research company to ‘benefit humanity’

Open-sourcing AI development to prevent an AI superpower takeover
December 11, 2015

OpenAI ft

Elon Musk and associates announced OpenAI, a non-profit AI research company, on Friday (Dec. 11), committing $1 billion toward their goal to “advance digital intelligence in the way that is most likely to benefit humanity as a whole, unconstrained by a need to generate financial return.”

The funding comes from a group of tech leaders including Musk, Reid Hoffman, Peter Thiel, and Amazon Web Services, but the… read more

Criminals and terrorists can fly drones too

Drones are no longer the sole domain of the military, and just as with many new technologies, they can easily fall into the wrong hands,  global security advisor, writer and consultant  reports in Time.

Criminal organizations are early adopters of technology, and some have already used UAVs and other forms of robotics to violate the law… read more

Amazingly realistic digital screen characters are finally here

Zoe

Meet Zoe: a digital talking head. She can express a range of human emotions on demand with “unprecedented realism” and could herald a new era of human-computer interaction, according to researchers at Toshiba’s Cambridge Research Lab and the University of Cambridge’s Department of Engineering, who created her.

Zoe, or her offspring, could be used as a visible version of Siri, as… read more

Are you in pain, but your doc won’t increase your hydrocodone dosage (or you don’t want to overdose)?

University of Texas at Arlington researchers may have a (future) drug-free fix: electrical stimulation of a deep middle-brain structure that blocks pain signals at the spinal cord level while triggering release of pleasure-associated dopamine to reduce the associated emotional distress.

“This is the first study to use a… read more

The music of the silks

Researchers synthesize a new kind of silk fiber --- and find that music can help fine-tune the material’s properties
November 30, 2012

This diagram of the molecular structure of one of the artificially produced versions of spider silk depicts one that turned out to form strong, well-linked fibers. A different structure, made using a variation of the same methods, was not able to form into the long fibers needed to make it useful. Musical compositions based on the two structures helped to show how they differed. (Credit: Markus Buehler/MIT)

Research by MIT’s Markus Buehler — together with David Kaplan of Tufts University and Joyce Wong of Boston University — has synthesized new variants on silk’s natural structure, and found a method for making further improvements in the synthetic material.

The work stems from a collaboration of civil and environmental engineers, mathematicians, biomedical engineers and musical composers. The results are reported in a paper published… read more

Mass extinctions occurring over the past 260 million years were likely caused by comet and asteroid showers, scientists conclude in a new study published in an open-access paper in Monthly Notices of the Royal Astronomical Society.

For more than 30 years, scientists have argued about a controversial hypothesis relating to periodic mass extinctions and impact craters — caused by comet and asteroid showers — on Earth.
