dracodraconisGenetically modified bugs extract ethanol more efficiently than natural ones - according to Dartmouth College researchers. The team developed a set of genetically modified bacteria that could operate at 50 Celsius, and as a result were able to convert all five sugars present in wood-based cellulose, produced a product free of organic acids, and required 2.5 times less cellulase, an expensive component in the process.
Water bears survive rigours of space - Tardigrades, also known as "water bears" are tiny microscopic animals that are known to survive high pressure, intense radiation, and long periods of being dried out. A recent experiment exposed two species of tardigrades to space for 10 days, then were retrieved, returned to Earth, and rehydrated to find out how well they faired. 68% of those shielded from the sun recovered and reproduced normally. Only a few of those also exposed to the sun's rays survived to reproduce. See also this article.
Company claims to have made unclonable RFID - Verayo announced this month that they have developed an RFID chip that uses a form of electronic fingerprinting to make the chip unclonable. The idea is new so we'll see how long the claim stands.
LH Supercollider powers up tomorrow - Heads up for those of you thinking this is the end of the world. Of course, if you're right then nobody will around to say "I told you so".
Preschool bilingual children at increased risk of stuttering - but their recover rate is also higher than for unilingual children. This is based on a study of 317 children in Britain referred for stuttering.
