An ancient bathtub ring of mammoth fossils

...he deposits to reconstruct the high-water marks of many of the floods, the last of which occurred as recently as 12,000 to 15,000 years ago. "Now is the perfect time to collect geologic and paleontologic data," said George Last, a senior research scientist at the Department of Energy laboratory in Rich...

New knowledge improves rice quality

... a whole new era of rice quality research." For many years, rice breeders have focused on developing varieties that would boost production and provide some insect and weed resistance to help farmers reduce their use of pesticides; quality was not a high priority. However, major new advances in rice res...

How to steer a moving cell

...ical conditions. "A surprising finding was that many of the proteins identified in the neuronal network, the ‘wiring diagram?that controls early development of neural networks in the embryo, are also found to control the movement of normal and cancerous cells," said Klemke. "This is apparently a fund...

Premature births may be linked to seasonal levels of pesticides and nitrates in surface water

...other environmental contaminants is detrimental to many outcomes of pregnancy. As a neonatologist, I am seeing a growing number of birth defects, and preterm births, and I think we need to face up to environmental causes," said Dr Winchester, who is also director of Newborn Intensive Care Services at St. ...

Scientists: As rainfall changes, tropical plants may acclimate

Students invent protective pouch to enhance cell therapy

...is project because it has the potential to benefit many people. "It could provide an important new way to treat diabetes and fulminant liver failure," said Link, 22, of Holbrook, N.Y. "I know about the health problems associated with diabetes because my grandmother has it, and she has to give herself seve...

New technique will produce a better chromosome map

...dreds of examples of the same chromosomes. With so many crisp images to analyze, computer algorithms can accurately calculate the number, shape and location of the chromosome bands. "Two researchers might see the same image differently," said graduate research assistant Mert Dikmen, who uses computer v...

Invasion of the island bats

...cies in geographic seclusion. Since islands have many times fewer species than the continent, it seemed only logical that continents were rich sources from which islands drew only a small sample. Once isolated and with fewer species around, island organisms were thought to lose their competitive edge an...

Genetic roots of bipolar disorder revealed by first genome-wide study of illness

...t on the combined, small effects of variations in many different genes in the brain, none of which is pow...izing medications used to treat the condition help many patients. But some people do not respond to these medications, and clinicians need more options...

Scientists identify prion's infectious secret

Egyptians, not Greeks were true fathers of medicine

...with pharmaceutical preparations of today but that many of the remedies had therapeutic merit." The medical documents, which were first discovered in the mid-19th century, showed that ancient Egyptian physicians treated wounds with honey, resins and metals known to be antimicrobial. The team also di...

Diminishing dinosaur steps saved by laser and laptop

This information is very important for palaeontologists and dinosaur locomotion experts, because it gives an insight into the way these dinosaurs moved and the environments in which they lived. The on-going...

UCLA AIDS Institute researchers find a peptide that encourages HIV infection

...tribute to an emerging field of medicine." "So many people have tried to deliver genes into different kinds of cells," said study co-author Shen Pang, adjunct associate professor at the UCLA School of Dentistry and a member of the UCLA AIDS Institute. "If you know of some method that can enhance gene ...

LIAI scientists make important finding on cytomegalovirus transmission

...ry glands are a primary source of transmission for many viruses due to sneezing, coughing and kissing. Eliminating the virus at this critical juncture may significantly reduce CMV’s spread, he said. In the study, Croft said the research team used an antibody to block the action of the IL-10 protein ...

The longest carbon nanotubes you've ever seen

...d better conductors of electricity than copper and many other materials--could ultimately find use in smart fabrics, sensors and a host of other applications. To grow the aligned bundles of tiny tubes, the researchers combined advantages of chemical vapor deposition (CVD), a technique for creating thin...

Dealing deadly cancers a knockout punch

...ruses as a first-line and adjunctive treatment for many cancers. Reovirus, a non-pathogenic virus under development at Calgary, Alberta-based Oncolytics Biotech, has shown powerful anti-cancer activity against cultured tumor cells, in animal models, and in human clinical trials.
