Lunar garden to give astronauts a green thumb on the green cheese
While we’re not likely to see crops of any sort sprouting from the moon’s surface any time soon, researchers have built a prototype lunar greenhouse that could allow plants from Earth to be grown without soil on the moon or Mars. The membrane-covered module can be collapsed to a 4-foot (1.2m) wide disk for interplanetary travel and contains water-cooled sodium vapor lamps and long envelopes that would be loaded with seeds, ready to sprout hydroponically.

Electron switch could make thin, light, high-powered organic batteries a reality
There’s no arguing that batteries are an essential element of today’s electronics landscape. Without them our mobile devices would be a lot less mobile and we might still be crank starting our cars. The explosion in mobile electronic devices enabled by batteries and miniaturization has a major downside in the form of discarded batteries, the majority of which contain toxic heavy metals. Chemists have now discovered a new way to pass electrons back and forth between two molecules that could see the development of organic batteries that are lightweight and work without the need for toxic heavy metals.

Two-photon walk a giant stride for quantum computing
Research conducted at the University of Bristol means a number of quantum computing algorithms may soon be able to execute calculations of a complexity far beyond what today's computers allow us to do. The breakthrough involves the use of a specially designed optical chip to perform what's known as a "quantum walk" with two particles ... and it suggests the era of quantum computing may be approaching faster than the scientific establishment had predicted.

A team of biomedical engineers at Taiwan’s National Cheng Kung University has created a new “on-chip” method to identify bacteria. By creating microchannels between two roughened glass slides containing gold electrodes, the researchers are able to sort and concentrate bacteria. A form of spectroscopy is then applied to identify them, providing a portable device that can be used for tasks like food monitoring and blood-screening. Read More
“Seeing” NeuFlow supercomputer based on the human visual system
The brain’s ability to quickly visually interpret our environment requires such an enormous number of computations it is pretty amazing that it accomplishes this feat so quickly and with seemingly little effort. Coming up with a computer-driven system that can mimic the human brain in visually recognizing objects, however, has proven difficult, but now Euginio Culurciello of Yale’s School of Engineering & Applied Sciences has developed a supercomputer based on the human visual system that operates more quickly and efficiently than ever before.

The cloning of human viruses may sound like the stuff of biological warfare, but breakthroughs in the area are helping in the development of antivirals and vaccines for life-threatening diseases. Now Welsh scientists have made the first complete copy of the virus Human cytomegalovirus (HCMV) – a common infectious disease that is responsible for congenital malformations and potentially deadly to transplant patients or HIV/AIDS carriers.

Touch-sensitive artificial skin created using rubber film
It’s truly touching news... no sooner do we hear about the pressure-sensitive artificial skin created at UC Berkeley, than fellow Californians at Stanford University announce that they have also created such a material. While Berkeley’s skin relies on carbon nanotubes to detect pressure, however, Stanford’s skin utilizes a thin rubber sheet made up of tiny pyramids. It is reportedly so sensitive that it can “feel” the weight of a butterfly. Read More
Graphene is pretty amazing stuff. Just a couple of months ago, we heard about how the one-atom thick sheets of bonded carbon atoms had been used to create the strongest pseudo-electric magnetic fields ever sustained in a lab – and that was just the latest use that had been discovered for it. Now, word comes from Harvard University and MIT that graphene could be used to rapidly sequence DNA. Read More
Artificial pressure-sensitive skin created from nanowires
Using a process described as “a lint roller in reverse,” engineers from the University of California, Berkeley, have created a pressure-sensitive electronic artificial skin from semiconductor nanowires. This “e-skin,” as it’s called, could one day be used to allow robots to perform tasks that require both grip and a delicate touch, or to provide a sense of touch in patients’ prosthetic limbs.

In the past few months, we’ve received announcements regarding the mapped genomes of wheat, of apples, and even the repulsive human body louse. Now, researchers from the US Department of Agriculture (USDA) have sequenced 90 percent of the genome of Meleagris gallopavo, which you may know as the domestic turkey. Read More
