Deep sea buffet for bone-devouring worms

... four additional host species in only three years, suggests that the Osedax worms and their bacterial 'partners' are likely to play substantial roles in the cycling of nutrients into the surrounding deep-sea community." This can be put into context by considering that the Osedax worms and their symbiotic bac...

Vineyard weeds found to host Pierce's disease of grapes

...t released in the September issue of Plant Disease suggests that weeds commonly found in California's wine country may enable the spread of Pierce's disease of grapes, one of the most destructive plant diseases affecting grapes. Pierce's disease is caused by Xylella fastidiosa, a bacterium transmitted by sha...

Clear rules needed to govern deep sea bioprospecting: UNU

The guidelines could facilitate cooperation and coordination between states and, drawing on existing global and regional instrument...

Opiates Better Than Sedatives For Treating Newborns In Withdrawal

...ring from opiate withdrawal. However, new research suggests that opiates themselves are superior to sedatives for treating infants born to women who used heroin or methadone while pregnant. Opiates appear to better "ameliorate the withdrawal, facilitate feeding and potentially reduce the likelihood of seizur...

Researchers discover new route to hemoglobin synthesis

Researchers create functioning artificial proteins using nature's rules

...r they work within an actual organism. "Our work suggests that modern-day proteins have likely inherited much of the information specifying their structure and basic aspects of function from their ancestors, but it is also possible that they have been fine-tuned over time to have their own idiosyncratic fea...

Sugar helps control cell division

...sphate groups for the same spots on proteins. Hart suggests that a particular balance between O-GlcNAc and phosphates on proteins may help fine-tune their activities. The researchers' next steps are to examine select proteins modified by O-GlcNAc and found at locations important for various steps in cell div...

Virginia Tech, Nanjing Institute researchers discover half-billion year-old fossils

...." Zhou said, "And the way they occur in the rocks suggests that they were flat-lying organisms sprawling on the ocean floor 550 million years ago, much like some fungi, lichen, or algae do today." The resemblance to modern fungi, lichen, or algae may stop at the seemingly similar life position on ocean floo...

Ancient DNA confirms single origin of Malagasy primates

...our study contribute to the mountain evidence that suggests that prospects for ancient DNA studies from the tropics are less promising than those from higher latitudes, but when the results are potentially of such compelling interest, it's always worth a try," she said. ...

Opiate cocktail may spare cells from morphine's dark side

... hallmark of opiate tolerance and dependence. This suggests that the promotion of MOP-receptor internalization might prevent such cellular signaling imbalances, and indeed past work from Whistler indicated that mutant versions of the receptor that are more readily internalized were associated with reduced lev...

World-first technology enables study of ancient bacteria

...aviour of the mysterious hydrates. One theory now suggests that when the covering of "methane ice" which exists over much of the seabed of the Bermuda Triangle becomes unstable; this causes instability of the sea and an explosive mixture of air and methane above. Any ships or planes travelling over the area ...

Genomics researchers discover protein deficit that causes drug toxicity

...goes wrong under certain genetic conditions -- and suggests mechanisms which might help predict which genetic changes could alter the effect of drugs. Prior efforts to explain the mystery of thiopurine metabolism had focused on biochemical mechanisms -- not changes in protein levels. Background Researchers ...

Evolution of life on Earth may hold key to finding life in outer space

...sionally RNA as genetic material," Fox said. "This suggests life had a single origin from an earlier 'prebiotic' world, and research in NASA's Exobiology Program seeks to understand how this happened. The results of this type of research also help guide the search for life elsewhere in the universe, which is ...

Variant prion protein causes infection but no symptoms

...wasting disease in deer and elk. Now, new research suggests that a variant form of abnormal prion protein--one lacking an "anchor" into the cell membrane--may be unable to signal cells to start the lethal disease process, according to scientists at the Rocky Mountain Laboratories (RML), part of the National I...

UCLA researchers identify key enzyme linked to childhood blindness

... retinas of Leber patients for a long time. "This suggests that replacement of RPE65 by gene therapy should correct the blindness in these children, as was observed in mice and dogs with RPE65 mutations," Travis said. "This is a major breakthrough in understanding the visual cycle. It has ramifications for s...

Single gene is genetic switch for fly sexual behavior

The finding suggests that the "essential difference in sexual behavior between males and females lies in the functioning of this circuit and not its construction," according to the researchers. Dickson and colleagues have already begun collaborations with other research...

Forsyth scientists find three bacteria associated with oral cancer

"Finding bacteria associated with OSCC en...
