According to the newly published autobiography of Yang Liwei, head of China's first manned space mission in 2003, the crew's meals included dog meat from Huajiang county, which is renowned for its health benefits.
The meat is claimed to "cure high blood pressure, help build up old people's health, and reduce frequent urination," handy on a long voyage.
Long before you even feel sick, a new Darpa-funded bio-sensor will know what ails you. Researchers at Duke University are developing a device that can betray exposure to a virus even before a person's first sneeze, Wired's DangerRoom blog reports.
The sensor detects changes in gene expression that occur in people exposed to viruses like the common cold, flu, or the respiratory syncytial virus.
C-Crete, a startup company that makes a nano-engineered cement, has won $120,000 in the school's Entrepreneurship Competition. C-Crete's cement is reportedly stronger than any extant cement, and reduces CO2 emissions. Runners-up included makers of a nano-engineered insulin chewing gum and a silent alarm clock that was not nano-engineered.
Researchers at the Lawrence Livermore National Lab have taken a big step toward bridging the gap between mind and machine. Using ATP – adenosine triphosphate, the molecular medium of energy exchange present in nearly all living cells – the team has created a novel transistor that could allow electronic devices that can be hooked directly into the nervous system.
In what the BBC is calling "a claim that is likely to be met with some scepticism," North Korea has announced that it has made huge strides toward developing thermonuclear power, going so far as to claim that the nation's scientists have built a "unique thermo-nuclear reaction device."
We've got your skepticism right here.
Nanotech has opened the door to some serious sci-fi possibilities: tiny robots -- built by other tiny robots -- that swim in our bloodstreams eradicating infection or hunting tumors, or perhaps assembling miniscule electronic components. But programming such tiny objects to do what we want presents a problem: commands need space to exist, and space is limited aboard a nanobot. But two papers just published in the journal Nature today highlight an interesting and promising approach to this problem: embedding the commands in the nanobots' environments.
One of the richest men in history is spreading his wealth around again. The Bill & Melinda Gates Foundation announced its fourth round of Grand Challenges Explorations grants this week, funding 78 research projects in 18 countries on six continents with $100,000 each to pursue everything from better cell phone microscopes to stronger malaria deterrents to male contraceptive techniques.
Given the financial situations in Greece, Spain, and Portugal in recent weeks, the Euro Zone has plenty of reason to be down on itself. But Poland is showing a bit of financial-sector flash this week, becoming the first nation in Europe to install biometric ATM machines that read fingerprints rather than magnetic cards.
Silicon chips are on the way out, at least if Duke University engineer Chris Dwyer has his way. The professor of electrical and computer engineering says a single grad student using the unique properties of DNA to coax circuits into assembling themselves could produce more logic circuits in a single day than the entire global silicon chip industry could produce in a month.
With existing camera technology, capturing 3-D images as the biological eye does is difficult and time consuming; basic stereoscopy requires two images to create a single 3-D frame, which means that to shoot 3-D video you need at least two cameras rolling on the same subject at the same time (even the high-tech gear behind Avatar required two different lenses). But engineers at Fondazione Bruno Kessler (FBK) in Italy have created a single camera that can capture the third dimension, using laser detection and creative use of CMOS technology.
And that's not all: The camera's sensor also records the smallest pixel currently in the field, a mere ten millionths of a meter (roughly one tenth the size of a human hair). Add it all up, and it's one pretty sweet piece of machinery, with the ability to capture not only the highest quality of detail in images, but to produce a depth of vision you can only get by adding the third dimension.
