Swiss research scientists utilize robotic therapy and chemical stimulation to return mobil...

Researchers working at the Swiss Federal Institute of Technology have successfully made use of electrical and chemical stimulation techniques to excite neurons in the lower spinal cord of previously paralyzed rats, enabling the subject rodents to walk and even run when suspended by a vest which provides balance and restricts movement to the hind legs only.  Read More

Engineered microvessels can form bends and T-junctions, like this one. The blue dots are t...

A team of bioengineers at the University of Washington has developed the first structure for growing small human blood vessels in the laboratory. The vessels behave remarkably like those in a living human and offer a better and much more modular approach to studying blood-related diseases, testing drugs and, one day, growing human tissues for transplant.  Read More

This drawing shows a double-walled carbon nanotube. Each tube is made of a rolled-up sheet...

Stanford researchers have found that concentric carbon nanotubes, with the outer layer riddled by defects and impurities, could be a cheap alternative for some of the platinum catalysts that convert hydrogen and oxygen into water in fuel cells and metal-air batteries.  Read More

The scientists of the aptly-named Tomato Genome Consortium have successfully sequenced the genome of the domestic tomato (Solanum lycopersicum), specifically the domestic cultivar known as Heinz 1706. The genome is made up of 35,000 genes spread over 12 chromosomes. In addition to presenting a "high quality" genome of the species, the researches also produced a draft sequence of its closest wild relative, the currant tomato (Solanum pimpinellifolium).  Read More

Looking through a UV-blocking filter, the green spots show the location of active catalyst...

Storing solar energy for the periods of time when the sun isn’t shining is key to improving solar technology. The energy produced can be stored in batteries or used to produce fuel that can act as storage. Solar fuel processes are generally modeled on photosynthesis, the natural process whereby plants convert sunlight into chemical energy in the form of biomass and release oxygen into the atmosphere. Current options are expensive, but a group or researchers from the University of Wisconsin-Madison claim they have found a faster, cheaper method to find electrocatalysts that improve the water oxidation process in the search for solar energy storage.  Read More

The 520 genome sequences released are matched sets of normal and tumor tissue samples from...

As part of an ongoing effort to facilitate swifter progress in the fight against cancer and other related diseases, the St. Jude Children's Hospital-Washington University Pediatric Cancer Genome Project has released a vast amount of human cancer genome data, which is now available to scientists globally. The volume of information offered amounts to more than double the data previously open to scientists from all the other human genome sources combined.  Read More

The new chemical chip can control the delivery of the neurotransmitter acetylcholine, enab...

While the silicon chips found in the electronic devices that we rely on every day are built around the flow of electrons through circuits, with the development of an “integrated chemical chip,” a doctoral student in Organic Electronics at Sweden’s Linköping University has created the basis for an entirely new circuit technology based on the transmission of ions and molecules.  Read More

A piece of steel treated with the graphene varnish, in front of an untreated sample

Hexavalent chromium compounds are a key ingredient in coatings used to rust-proof steel. They also happen to be carcinogenic. Researchers, therefore, have been looking for non-toxic alternatives that could be used to keep steel items from corroding. Recently, scientists from the University at Buffalo announced that they have developed such a substance. It’s a varnish that incorporates graphene, the one-atom-thick carbon sheeting material that is the thinnest and strongest substance known to exist.  Read More

Most people associate vacuum tubes with a time when a single computer took up several rooms and "debugging" meant removing the insects stuck in the valves, but this technology may be in for a resurgence with news that researchers at NASA and the National Nanofab Center in South Korea are working on a miniaturized "vacuum channel transistor" - a best-of-both-worlds device that could find application in space and high-radiation environments.  Read More

ISS astronauts aboard the Dragon spacecraft, last Saturday morning (Photo: NASA)

After making history last Friday by becoming the first private spacecraft to ever reach the International Space Station (ISS), SpaceX’s Dragon capsule was successfully boarded by ISS astronauts the following morning. The interior of the craft was reportedly in good condition, and according to astronaut Don Pettit, it smelled like a new car.  Read More
