How to create a spray-paint battery

Turn any surface into a battery
June 29, 2012

Li-ion battery

lithium-ion battery that can be painted on virtually any surface has been developed by Rice University researchers.

The rechargeable battery, created in the lab of Rice materials scientist Pulickel Ajayan, consists of spray-painted layers, each representing the components in a traditional battery.

“This means traditional packaging for batteries has given way to a much more flexible approach that allows all kinds of new design and integration possibilities… read more

Craig Venter imagines a world with printable life forms

Craig Venter imagines a future where you can download software, print a vaccine, inject it, and presto! Contagion averted.

“It’s a 3-D printer for DNA, a 3-D printer for life,” Venter said at the inaugural Wired Health Conference in New York City, Wired Science reports.

The geneticist and his team of scientists are already testing out a version of his digital biological converter, or “teleporter.”… read more

A ‘shockingly bright’ gamma-ray burst

May 7, 2013

Swift's X-Ray Telescope took this 0.1-second exposure of GRB 130427A at 3:50 a.m. EDT on April 27, just moments after Swift and Fermi triggered on the outburst. The image is 6.5 arcminutes across. (Credit: NASA/Swift/Stefan Immler)

A record-setting blast of gamma rays from a dying star in a galaxy about 3.6 billion light-years away has wowed astronomers around the world — the highest-energy light ever detected from such an event.

At 3:47 a.m. EDT, April 27, Fermi’s Gamma-ray Burst Monitor (GBM) triggered on an eruption, designated GRB 130427A, of high-energy light in the constellation Leo.

The Fermi Large Area Telescope (LAT) recorded one gamma ray… read more

Meet ‘Flame,’ the massive spy malware infiltrating Iranian computers

May 31, 2012

Flame-Infection-Map_Kaspersky-660x429

A massive, highly sophisticated piece of malware has been newly found infecting systems in Iran and elsewhere and is believed to be part of a well-coordinated, ongoing, state-run cyberespionage operation, Wired Threat Level reports.

Dubbed “Flame,” the malware is an espionage toolkit that has been infecting targeted systems in Iran, Lebanon, Syria, Sudan, and other countries in the Middle East and North Africa for at least two… read more

Are restrictions to scientific research costing lives?

September 6, 2012

CensorsOnCampusSep12Cover

In “Censors on Campus,” Index on Censorship magazine asks whether lives might be saved by making vital research freely available.

Some parts of Asia and Africa the fight against malaria is severely hampered because doctors and researchers are denied full access to the 3,000 articles published on the disease each year. At the same time, scientists living and working in developing countries are prevented from becoming global… read more

Intelligence could not be linked to 12 specific genetic variants, contradicting studies

October 4, 2012

IQ_curve

Most of the specific genes long thought to be linked to intelligence probably have no bearing on one’s IQ, and new study by psychological scientist Christopher Chabris of Union College has revealed.

Chabris and David Laibson, a Harvard economist, led an international team of researchers that analyzed a dozen genes using large data sets that included both intelligence testing and genetic data.

In nearly every case, the researchers found… read more

State-of-the-art virtual-reality system is key to medical discovery

For team of neurosurgeons and researchers, CAVE2 could revolutionize stroke prevention and treatment
December 13, 2012

Surgeons from the University of Illinois Hospital & Health Sciences Systems Neurosurgery Department view a simulation of the human brain vasculature and cortical tissue in the CAVE2 Hybrid Reality Environment.

A team of neurosurgeons from the College of Medicine at the University of Illinois at Chicago (UIC) recently stepped into CAVE2 — a next-generation, large-scale, 320-degree, immersive, 3-D virtual environment — to solve a vexing problem that presented itself in the arteries of the brain of a real patient.

The method they used could someday benefit hundreds of thousands of Americans who fall… read more

Cloud computing modernizes education in China

May 13, 2013

3tcloud

Chinese cloud services provider 3Tcloud is deploying the country’s biggest education cloud project to optimize resource allocation and cut maintenance cost, ZDNET reports.

According to a report last week on Chinese tech site CCIDNet.com, the city of Zhuji in Zhejiang — one of China’s most developed provinces — has installed more than 6,000 3Tcloud computing terminal devices in 118 schools.

The project,… read more

Proteins remember the past to predict the future

October 5, 2012

Motor_Proteins

The most efficient machines remember what has happened to them, and use that memory to predict what the future holds.

That is the conclusion of a theoretical study by Susanne Still, a computer scientist at the University of Hawaii at Manoa and her colleagues, and it should apply equally to “machines” ranging from molecular enzymes to computers, Nature News reports. The finding could help to improve scientific… read more

Most of the harmful mutations in people arose in the past 5,000 to 10,000 years

European Americans have a larger proportion of potentially harmful variants than African Americans --- probably an artefact of their original migration out of Africa

The human genome has been busy over the past 5,000 years. Human populations have grown exponentially, and new genetic mutations arise with each generation, says Nature News.

Humans now have a vast abundance of rare genetic variants in the protein-encoding sections of the genome.

A study published in Nature now helps to clarify when many of those rare variants arose.

Researchers used deep sequencing to locate… read more

The slower you grow, the longer you live

Fish study may also apply to humans
January 3, 2013

Gasterosteus_aculeatus

New research from the University of Glasgow suggests that lifespan is affected by the rate at which bodies grow early in life: manipulating growth rates in stickleback fish can extend their lifespan by nearly a third or reduce it by 15 percent.

A team from the University’s Institute of Biodiversity, Animal Health and Comparative Medicine altered the growth rate of 240 fish by exposing… read more

Nanoparticles loaded with bee venom kill HIV

March 11, 2013

Nanoparticles (purple) carrying melittin (green) fuse with HIV (small circles with spiked outer ring), destroying the virus’s protective envelope. Molecular bumpers (small red ovals) prevent the nanoparticles from harming the body’s normal cells, which are much larger in size. (Credit:

Nanoparticles carrying a toxin found in bee venom can destroy human immunodeficiency virus (HIV) while leaving surrounding cells unharmed, researchers at Washington University School of Medicine in St. Louis have shown.

The finding is an important step toward developing a vaginal gel that may prevent the spread of HIV, the virus that causes AIDS.“Our hope is that in places where HIV is running rampant, people… read more

Mathematicians at UC Davis have come up with a new way to crinkle up the fabric of space-time — at least in theory.

“We show that space-time cannot be locally flat at a point where two shock waves collide,” said Blake Temple, professor of mathematics at UC Davis. “This is a new kind of singularity in general relativity.”

About two hours after landing on Mars and beaming back its first image, NASA’s Curiosity rover transmitted a higher-resolution image of its new Martian home, Gale Crater.

“Curiosity’s landing site is beginning to come into focus,” said John Grotzinger, project manager of NASA’s Mars Science Laboratory mission, at the California Institute of Technology in Pasadena.

“In the image, we are looking to the northwest. What you see on… read more

Neural_stem_cells_regenerate_axons

In a study at the University of California, San Diego and VA San Diego Healthcare, researchers were able to regenerate “an astonishing degree” of axonal growth at the site of severe spinal cord injury in rats.

Their research revealed that early stage neurons have the ability to survive and extend axons to form new, functional neuronal relays across an injury site in the adult central… read more
