Billionaire investor Peter Thiel’s philanthropic foundation has announced a six-figure grant for bioprinted meat, part of an ambitious plan to bring to the world’s dinner tables a set of technologies originally developed for creating medical-grade tissues, CNET reports.

The recipient of the Thiel Foundation’s grant, a Columbia, Mo.-based startup named Modern Meadow, is pitching bioprinted meat as a more environmentally-friendly way to satisfy… 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 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

Representative Steve Israel, Democrat of New York wants to extend an existing law, set to expire this year, that makes weapons that are undetectable by security scanners — like a printed all-plastic gun — illegal, The New York Times reports.

But there are also major technical obstacles to creating an entire gun on a 3-D printer, not the least of which is that a plastic gun would… read more

Research debunks the ‘IQ myth’

December 21, 2012

After conducting the largest online intelligence study on record, with more than 100,000 participants, a Canadian Western University-led research team has concluded that the notion of measuring one’s intelligence quotient or IQ by a singular, standardized test is highly misleading.

Utilizing an online study open to anyone, anywhere in the world, the researchers asked respondents to complete 12 cognitive tests tapping memory, reasoning, attention and… read more

Google Glass patent applications: bone conduction, laser-projected keyboard, more

January 29, 2013

laser-projected keyboard.-featured

Recent patent applications related to Google Glass are providing insight into the hardware behind the Glasses.

Bone conduction for covert audio. This would allow more privacy so that no one can overhear a conversation; a vibration transducer allows the technology to work without a direct connection. U.S. patent application

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

A 3D-printed Moon base baked from lunar dust

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

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

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 robot as cheap, easy-to-use, and safe as an iPhone

August 26, 2012

rethink_robotics

Rethink Robotics’ goal is that its [forthcoming] cheap, easy-to-use, safe robot will be to industrial robots what the personal computer was to the mainframe computer, or the iPhone was to the traditional phone, says The New York Times writer Thomas L. Friedman.

“That is, it will bring robots to the small business and even home and enable people to write apps for them the way they do with PCs… read more

Rice unveils super-efficient solar-energy technology

November 21, 2012

The solar steam device developed at Rice University has an overall energy efficiency of 24 percent, far surpassing that of photovoltaic solar panels. It may first be used in sanitation and water-purification applications in the developing world. (Credit: Jeff Fitlow/Rice University)

Rice University scientists have unveiled a revolutionary new technology that uses silicon dioxide/gold nanoshells and N115 carbon nanoparticles to convert solar energy directly into steam. The new “solar steam” method from Rice’s Laboratory for Nanophotonics (LANP) is so effective it can even produce steam from icy cold water.

The technology has an overall energy efficiency of 24 percent. Photovoltaic solar panels, by comparison, typically have… 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

Is faster-than-light travel possible?

July 23, 2013

Alcubierre warp drive

Engineers at NASA Johnson Space Center are designing instruments to find out, by slightly warping the trajectory of a photon and measuring the distance it travels, The New York Times reports.

Inspiration for the research came from Mexican physicist Miguel Alcubierre, who proposed in 1994 a method of stretching space in a wave which would in theory cause the fabric of space ahead of a spacecraft to… read more

Graphene micro-supercapacitors to replace batteries for microelectonics devices

Will power biomedical implants, active RFID tags, embedded micro-sensors, and flexible electronics
February 27, 2013

Micro-supercapacitor

UCLA researchers have developed a groundbreaking technique that uses a DVD burner to fabricate miniature graphene-based supercapacitors — devices that can charge and discharge a hundred to a thousand times faster than standard batteries.

These micro-supercapacitors, made from a one-atom–thick layer of carbon, can be easily manufactured and readily integrated into small devices, such as next-generation pacemakers.

The new cost-effective fabrication method holds promise for the… read more
