Worm Seeks Worm: Caltech Researchers Find Chemical Cues Driving Aggregation in Nematodes
Worm Seeks Worm: Caltech Researchers Find Chemical Cues Driving Aggregation in Nematodes
Scientists have long seen evidence of social behavior among many species of animals, both on the earth and in the sea. Dolphins frolic together, lions live in packs, and hornets construct nests that can house a large number of the insects. And, right under our feet, it appears that nematodes—also known as roundworms—are having their own little gatherings in the soil.

'Lost world' discovered around Antarctic vents
Communities of species previously unknown to science have been discovered on the seafloor near Antarctica, clustered in the hot, dark environment surrounding hydrothermal vents. The discoveries, made by teams led by the University of Oxford, University of Southampton, the National Oceanography Centre, and British Antarctic Survey, include new species of yeti crab, starfish, barnacles, and sea anemones, and even an octopus probably new to science.

Fighting the UK's deadliest cancer
Fighting the UK’s deadliest cancer
A promising line of attack against pancreatitis and pancreatic cancer is to be explored further at Cardiff, thanks to substantial new funding from the Medical Research Council (MRC). Pancreatitis can develop when the enzymes needed for digestion turn on the pancreas itself. Chronic pancreatitis increases the risk of pancreatic cancer, which has the lowest five-year survival rate of all common cancers in the UK.

Go to work on a Christmas card: UK’s wrapping paper and festive cards could provide energy to send a bus to the moon more than 20 times
If all the UK's discarded wrapping paper and Christmas cards were collected and fermented, they could make enough biofuel to run a double-decker bus to the moon and back more than 20 times, according to the researchers behind a new scientific study. The study, by scientists at Imperial College London, demonstrates that industrial quantities of waste paper could be turned into high grade biofuel, to power motor vehicles, by fermenting the paper using microorganisms.

First person: How we discovered fluoride riboswitches
Scientific discoveries come through many different means. Breakthroughs can result from purposefully-executed research projects that are perhaps punctuated with unexpected flashes of insight. In rare cases, discoveries occur through a chain of highly improbable, very lucky, occurrences. I strongly prefer my research team to stay on the first path and use their highly developed scientific skills to guide their efforts towards a rational goal.

Scientists Pioneer New Method for Watching Proteins Fold
A protein's function depends on both the chains of molecules it is made of and the way those chains are folded. And while figuring out the former is relatively easy, the latter represents a huge challenge with serious implications because many diseases are the result of misfolded proteins. Now, a team of chemists at the University of Pennsylvania has devised a way to watch proteins fold in "real-time," which could lead to a better understanding of protein folding and misfolding in general.

New insight into why locusts swarm
New insight into why locusts swarm
Learning is when you change your behaviour in the light of new experience, and this is what a locust needs to do when it gets caught up in the crowd." —Dr Swidbert Ott from the University of Cambridge Department of Zoology New research has found that a protein associated with learning and memory plays an integral role in changing the behaviour of locusts from that of harmless grasshoppers into swarming pests.

New sugar a treat for diabetes treatment
New sugar a treat for diabetes treatment
Researchers from The Australian National University have discovered a new treatment for Type-1 diabetes - an autoimmune disease which currently affects some 130,000 Australians. Charmaine Simeonovic and Professor Christopher Parish from The John Curtin School of Medical Research have identified a previously unknown process which causes destruction of the insulin-producing beta cells in the pancreas.

Upper atmosphere facilitates changes that let mercury enter food chain
Upper atmosphere facilitates changes that let mercury enter food chain
Humans pump thousands of tons of vapor from the metallic element mercury into the atmosphere each year, and it can remain suspended for long periods before being changed into a form that is easily removed from the atmosphere. New research shows that the upper troposphere and lower stratosphere work to transform elemental mercury into oxidized mercury, which can easily be deposited into aquatic ecosystems and ultimately enter the food chain.

Discovery of a ‘Dark State’ Could Mean a Brighter Future for Solar Energy
AUSTIN, Texas — The efficiency of conventional solar cells could be significantly increased, according to new research on the mechanisms of solar energy conversion led by chemist Xiaoyang Zhu at The University of Texas at Austin. Zhu and his team have discovered that it's possible to double the number of electrons harvested from one photon of sunlight using an organic plastic semiconductor material.

Team designs a bandage that spurs, guides blood vessel growth
CHAMPAIGN, lll. Researchers have developed a bandage that stimulates and directs blood vessel growth on the surface of a wound. The bandage, called a "microvascular stamp," contains living cells that deliver growth factors to damaged tissues in a defined pattern. After a week, the pattern of the stamp "is written in blood vessels," the researchers report.

Nanocrystals Go Bare:
Researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered a universal technique for stripping nanocrystals of tether-like molecules that until now have posed as obstacles for their integration into devices. These findings could provide scientists with a clean slate for developing new nanocrystal-based technologies for energy storage, photovoltaics, smart windows, solar fuels and light-emitting diodes.
