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

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

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

Tesla Autopilot predicts collision ahead seconds before it happens

Tesla autopilot predicts

Hans Noordsij, a Dutch Tesla driver, uploaded a Dec. 27 dashcam video that dramatically shows the new radar processing capacity of Tesla’s Autopilot and resulting auto-breaking, DarkVision Hardware reports. The system’s radar saw ahead of the car in front and tracked two cars ahead on the road. Note the audible warning a second or so before the accident.

Criminals and terrorists can fly drones too

February 6, 2013

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

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

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

‘Information sabotage’ on Wikipedia claimed

Politically controversial science topics like acid rain, evolution, and climate change are vulnerable to "edit wars" by trolls
August 17, 2015

Research has moved online, with more than 80 percent of U.S. students using Wikipedia for research papers, but how reliable is controversial science information? (credit: Pixabay)

 

Wikipedia entries on politically controversial scientific topics can be unreliable due to “information sabotage,” according to an open-access paper published today in the journal PLOS One.

The authors (Gene E. Likens* and Adam M. Wilson*) analyzed Wikipedia edit histories for three politically controversial scientific topics (acid rain, evolution, and global warming), and four non-controversial scientific topics (the standard… 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

Mass extinctions linked to comet and asteroid showers

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.

The European Commission has selected the two research proposals it will fund to the tune of half-a-billion euros ($650 million U.S.) each, after a two-year, high-profile contest, Nature News reports.

The Human Brain Project, led by neuroscientist Henry Markram at the Swiss Federal Institute of Technology (EPFL) in Lausanne, plans to simulate the human brain in a supercomputer. (See “Brain inread more

Can an algorithm write a better news story than a human reporter?

Every 30 seconds or so, an algorithm developed by Narrative Science produces a computer-written news story, Wired reports.

The articles run on the websites of respected publishers like Forbes, as well as other Internet media powers (many of which are keeping their identities private).

We are all being watched, whether we like it or not.

It is a battle between you and the government — like Mad Magazine’s Spy vs. Spy comic, but it’s gSpy vs. iSpy, Andy Kessler, author of Eat People, writes in The Wall Street Journal.

There are thousands of toll booths at bridges and turnpikes across America recording your license plate. There are 4,214 red-light cameras… 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

Crewed missions to Mars such as Mars One may face dangerous levels of cosmic rays (energetic particles), according to a new paper in the journal Space Weather by University of New Hampshire (UNH) scientists.

This is due to a recent highly abnormal and extended lack of solar activity, resulting in extremely low densities and magnetic field strengths in the solar wind.

This results in a serious reduction in the… read more

Is faster-than-light travel possible?

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
