...tions. For example, how does wild salmon, which no longer provides the bulk of North America's salmon, remain a competitive product? One of the report's recommendations is that Alaskan salmon producers expand the use of labeling provided by the Marine Stewardship Council (MSC) which conveys to consumers...

Study examines risk of soft tissue sarcomas in hereditary retinoblastoma survivors

...ly to patients who received treatments that are no longer used. "Improved treatment can be expected to reduce the incidence of soft tissue (and bone) sarcomas associated with radiation," Meadows writes.

Children who sleep more weigh less

... allowing both younger and older children to sleep longer in the morning, as well as encouraging school districts to avoid very early school start times, might represent one important and relatively low-cost strategy to add to other efforts to help reduce childhood weight problems.?...

Fighting influenza & co. with 40,000 blood samples

Loss of a universal tRNA feature reported

... from the presence of an RNase P enzyme that is no longer capable of catalyzing abnormal cleavage at the -1 position in the tRNAHis precursor. It will also be revealing to see how different aminoacyl-tRNA synthetases have adapted to discriminate between their cognate or related substrates and the now less d...

3 proteins may play important role in nerve-cell repair

... cells grew extensions that were up to three times longer than those on nerve cells with normal levels of the proteins, and the extensions grew four to eight times faster than in control cells. "Our findings suggest that these three proteins could be important targets for treating stroke, brain and spin...

Yale biologists 'trick' viruses into extinction

"This approach has intriguing potential for new treatments against human viruses," said Turner. "A similar idea already exists in agriculture, where farmers use non-harvested 'trap crops' to lure in...

Tumor-suppressor gene is critical for placenta development

"This showed that the interaction of these two proteins is definitely important," Leone says. "It strongly suggests that E2f3 is a key player in mediating Rb function in stem cells and p...

Study to explore using magnets to correct 'sunken chest'

The use of the magnets has been deemed safe by the U.S. Food and Drug Administration, which has reviewed and approved the 3MP device. The internal magnet is laser-welded in a titanium case, assuring i...

Researchers urge monitoring of bone health during chemotherapy
