Selecting life: Scientists find new way to search for origin of life

...han could have been used by early life. One of the biggest questions in origins research, therefore, is how just the right blend of critical biomolecules was selected, concentrated, and organized from the diverse primordial "soup." Previous research by the Carnegie team and others has shown that many molecul...

Mysterious 'neural noise' actually primes brain for peak performance

...ork for the first time connects two of the brain's biggest mysteries; why it's so noisy, and how it can perform such complex calculations. As counter-intuitive as it sounds, the noise seems integral to making those calculations possible. In the last decade, Pouget and his colleagues in the University of R...

Embryonic patterning makes the feathers fly

... pathways with specific inhibitors. They got their biggest hits with the so-called mitogen-activated protein kinase, or MAPK, pathway. Manipulating the MAPK pathway produced a wide repertoire of feather patterning, from spots, to stripes, to homogenous patches, all reflecting varying degrees of inhibited fea...

New research shows big improvement in survival after stroke

...le globally and is widely recognised as one of the biggest killers in both Australia and New Zealand. In New Zealand, over 7,600 strokes occur each year, while over 53,000 strokes take place in Australia per annum. However, research into stroke rates has shown a steady decline in stroke in many industriali...

Hope for major advance in fighting world killer disease

... Government Children's Hospital in Chennai, is the biggest children's hospital in Asia. Once any further improvements are made following these trials, then Professor Williams expects the technique to spread round other clinicians in the region and elsewhere. His team has already received enquiries from t...

Public Library of Science to launch new, open access journal on neglected tropical diseases

...experts from developing countries, and some of the biggest names in tropical medicine and global health, including renowned health economist Jeffrey Sachs and the director of the World Health Organization's African river blindness control program, Uche Amazigo. Dr. Amazigo said: "PLoS Neglected Tropical Di...

Coral reefs are increasingly vulnerable to angry oceans

... that the threshold imposed by the previous year's biggest storm predicted the pattern of coral sizes and shapes almost perfectly. "There were a lot of table corals present that went right up to the threshold from the last big storm, and then suddenly nothing above it," said Connolly. "They even followed...

Stormy days ahead for coral reefs

... that the threshold imposed by the previous year's biggest storm predicted the pattern of coral sizes and shapes almost perfectly. "There were a lot of table corals present that went right up to the threshold from the last big storm, and then suddenly nothing above it," says Dr Connolly, a CoECRS researcher ...

Federal testing for mad cow disease a failure, law review editor says

...f exports through intense lobbying, but Japan, the biggest export market, continued to resist. The administration argued that there was no risk to humans because the second cow had not been slaughtered and the BSE infection had not gotten into the food supply. Last December, Japan partially lifted its ban,...

Researchers offer clues to how leaves patterns are formed

...for the final shape of the plant." But one of the biggest discoveries, perhaps the one with the most evolutionary implications, is that plants use the same mechanism to regulate vein formation in the leaf and branch formation on the main trunk and on the main root. The finding that the leaf is like a two-di...

Research highlights how bacteria produce energy

...t life forms could be the answer to one of today's biggest problems: providing sustainable, renewable energy for the future. Using a variety of natural food sources, bacteria can be used to create electricity, produce alternative fuels like ethanol and even boost the output of existing oil wells, according...

Virus has 'catastrophic' affect on red squirrels, research shows

...echnology to develop recommendations for England's biggest red squirrel refuge, Kielder Forest, Northumberland. The forest has played a leading role in developing conservation strategies for the red squirrel. The team identified four potential 'gateways' for grey squirrels and developed a strategy to manage ...

Computational model simulates AZT metabolism in mitochondria

... professor at VBI, commented: "HAART is one of the biggest success stories in modern medicine. The goal of our work is to help improve this successful treatment by understanding the toxic effects that AZT can have in some people. There are many different ways that AZT could possibly interfere with mitochondr...

Super-sized cassava plants may help fight hunger in Africa

The modified plants produced a maximum of 12 roots, compared to the seven roots produced by the non-modified plant. These modified plants also produced a third more leaves ?a maximum of 123...

Research identifies protein in mice that regulates bone formation

Mosquito spray increases toxicity of pyrethroids in creek, study finds

...s unexpected. "In this instance, it appeared the biggest concern was not the aquatic toxicity of the pyrethrin insecticide in the mosquito spray, but the fact that the non-toxic synergist actually synergized the 'wrong' thing - pyrethroid pesticides that were already in the creek sediments," said Weston. ...

Researchers win money to develop breath test to detect breast cancer

One of the biggest problems in fighting breast cancer is the lack of inexpensive, early detection diagnostic tools. Researchers at the University of Michigan hope to change that by developing a device to test breath for the presence of metabolites associated with bre...

The biggest current threat to albatross populations in the North Pacific is the longline fishing industry, which kills significant numbers of both black-footed and Laysan albatrosses. But the contaminants measured in this study may also take a toll. Comparable l...
