MIT chemical engineers have designed an injectable gel that responds to the body’s high temperature by forming a reinforcing network that makes the gel much more durable, allowing it to function over a longer period of time.
Gels that can be injected into the body, carrying drugs or cells that regenerate damaged tissue, hold promise for treating… read more
New artificial muscles made from nanotech yarns and infused with paraffin wax can lift more than 100,000 times their own weight and generate 85 times more mechanical power than the same size natural muscle, according to scientists at The University of Texas at Dallas and their international team from Australia, China, South Korea, Canada and Brazil.

Internet activists are warning that next month’s meeting of the International Telecommunications Union, a United Nations body charged with overseeing global communications, may have significant and potentially disastrous consequences for everyday Internet users, Mashable reports.
Called the World Conference on International Telecommunications, the meeting is intended to update some of the aging international law that governs the flow of information online. The meeting is mostly closed to… read more
A technique for growing virtually pure samples of single-wall carbon nanotubes (SWCNTs) with identical structures has been demonstrated by researchers from the University of Southern California (USC) and the National Institute of Standards and Technology (NIST).
They liken this process to “cloning” the nanotubes. If it can be suitably scaled up, their approach could solve an important materials problem in nanoelectronics: producing carbon nanotubes… read more
Single-wall carbon nanotubes (SWCNTs) may help protect DNA molecules from damage by oxidation, researchers at the National Institute of Standards and Technology (NIST) have found.
In nature, oxidation is a common chemical process in which a reactive chemical removes electrons from DNA and may increase the chance for mutations in cells.
More studies are needed to see if the in vitro protective effect of… read more
Newspapers have continued to churn out the same content while watching their advertisers steadily flee for sites like Craigslist, Yahoo, the Huffington Post/AOL, Facebook, and Google, says writer Will Oremus in Slate Future Tense. .
The chart above, from Statista’s Felix Richter, plots Google’s digital advertising revenue against the print advertising revenue of all U.S.… read more
Astronomers have identified an object that could be a planet wandering through space without a parent star at a distance of about 100 light-years. Its closeness and the absence of a nearby bright star have allowed the team to study its atmosphere in great detail.
Free-floating planets are planetary-mass objects that roam through space without any ties to a star. Possible… read more
NASA is considering plans for a hovering moon base parked in orbit about 60,000 kilometers from the moon’s far side, at Lagrange point 2 (EML-2), New Scientist reports.
There, the combined gravity of Earth and the moon would tug on a spacecraft with exactly the force needed for it to hover near the moon without spending fuel. This might assist human missions to an asteroid or to Mars… read more
MIT researchers have fabricated a three-dimensional, lightweight metamaterial lens that focuses radio waves with extreme precision.
The concave lens exhibits a property called negative refraction, bending electromagnetic waves — in this case, radio waves — in exactly the opposite sense from which a normal concave lens would work.
Concave lenses typically radiate radio waves… read more
Gross domestic product (GDP) can be boosted by cloud computing, the system in which remote computers on the Internet are used to store, manage and process data rather than the users’ local machines, according to a report to be published in the International Journal of Technology, Policy and Management.
The report suggests that governments should collaborate to boost the adoption… read more
Last year, Google TV devices received an update that added Google Play and simplified the entertainment discovery experience. The next update, starting this week, makes finding whatever you want on Google TV even faster and easier, Google TV Blog reports.
The update includes:
Just speak to watch TV shows and movies, start playing a YouTube video, open applications,
Hydrogen is an attractive fuel source because it can easily be converted into electric energy and gives off no greenhouse emissions. A group of chemists at the University of Rochester is now adding to its appeal by increasing the output of current light-driven hydrogen-production systems while lowering the cost.
The chemists say their work advances what is sometimes considered the “holy grail” of… read more
So far, alternative fuels from waste have not moved beyond small pilot plants, despite federal incentives to encourage companies to develop them. That could be about to change, The New York Times reports.
Officials at two companies that have built multimillion-dollar factories say they are very close to beginning large-scale, commercial production of these “cellulosic… read more
An international team led by the University of Edinburgh has discovered a new gene called miR-941 that helps explain how humans evolved evolved from apes by playing a crucial role in human brain development, and may shed light on how we learned to use tools and language.
The researchers say it is the first time that a new gene — carried only by humans and not by apes —… read more
University of Adelaide computer scientists are developing a network of sensors attached to objects and AI software to track what a senior is doing — a practical, low-cost solution for helping older people to keep living independently and safely in their own homes.
The researchers are adapting radio-frequency identification (RFID) and other sensor technologies to automatically identify and monitor human activity,… read more
