Prototype just-in-time medical device enables untrained bystanders to save lives

...of bystanders have had CPR training, and of those, fewer than 10% retained the knowledge only a few months after training. The JITS device prototype used in the study consisted of a dummy "victim," a pressure-sensing headrest, an anesthesia mask, defibrillator pads, and a video screen and speakers that t...

UVa researchers seek to unlock broccoli's cancer fighting secret

...id not have the gene for this enzyme developed far fewer cancers when given carcinogens. "If we can determine that this specific enzyme is the reason the compounds in broccoli work to prevent cancer, then these nutrients or similar chemicals could be turned into anti-cancer compounds," she says. The i...

Two central mysteries in genome inheritance solved at UCSD

The second paper from Desai's research group, to be published in the December 15 issue of Cell, identifies a different type of connection between chromosomes and microtubule polymers, which operates to discriminate between correct ...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

...lead author of the SCIENCE study. "Biofuels emit fewer pollutants than fossil fuels such as gasoline. In addition, poplar and related plants are vital managers of atmospheric carbon. Trees store captured carbon dioxide in their leaves, branches, stems, and roots. This natural process provides opportunit...

A fisheye view of the deadliest breast cancer

...r (IBC) is the deadliest form of the disease, with fewer than half of those diagnosed today having a five-year prognosis for survival. To find out what drives this most aggressive of human breast cancers, and to rapidly screen for drugs that might stop IBC, researchers at the University of California, Sa...

When the label says 'low fat,' calories can pile up, study says

...y low-fat-labeled foods have only about 30 percent fewer calories than their regular counterparts. "Often, the fat-free version is not much lower calorie than the regular version," Wansink said. "Low-fat labels trick people into eating more than regular labels. But the cruel twist is that these labels have...

Plant-derived molecules, genetic manipulation point to future chemoprevention methods

The research suggests that reducing levels of t...

Antibody extends life of mice with breast cancer

The research group currently is determining if JAA-F11 could increase the effectiveness of existing cancer drugs, she said, as well as studying the possibility of using the antibody as a vehicle for the target...

Artificial cornea offers better results for infants, some blind patients

In both groups, though, Aquavella said the quality of the patient's eyesight was often limited by other deficiencies in the eye. The partnership between Aquavella and Dohlman stretches back nearly half a century. Aqu...

Study IDs protein that inhibits HIV from growing in cell cultures

...the number of CD4 receptors available to HIV. With fewer places for HIV to "dock," less HIV enters the cells to inflict destruction. However, Xiang cautioned, this is only part of the story, and the researchers must continue work to understand how the NS5A protein exerts its total effect. "Before N...

Scientist's persistence sheds light on marine science riddle

...size in animals isolated on islands: reduced area, fewer predators, less competition, and resource limitation. "Only resource limitation clearly applies to deep-sea animals," said Rosenberg. "We know there is less food available in the deep sea than in shallow water, but the area of the deep sea is much la...

Study illuminates how the plague bacteria causes disease

... that lacked the GDI activity caused significantly fewer problems for infected mice compared to normal bacteria. "Earlier studies that focused only on the protein's kinase activity had missed half the picture," Stebbins said. "The GDI domain seems to have an even bigger effect on host cells in culture, an...

Cities change the songs of birds

They add that such rapid genetic changes are likely to occur much more quickly in organisms with short life spans, such as a fruit fly, which can produce several generations in a single year. "In the long term, this suggests tha...
