In the new report, researchers describe the use of sodium acetate as an inexpensive and environmentally friendly con...

Faulty cell membrane repair causes heart disease

...hree types of muscular dystrophy. The new study expands knowledge of dysferlin function, showing that dysferlin-mediated membrane repair is also important in heart muscle cells and suggests that inadequate membrane repair can also lead to cardiomyopathy. "If we could boost this repair mechanism, it migh...

University of Arizona launches major scientific research initiative at Biosphere 2

Bass, substantially expands the University's ability to link teaching, scholarship and creativity to the needs of Arizona and our larger global community, President Shelton said. Biosphere 2 will provide our faculty and students exceptional opportunities to address major envir...

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

...rations in surface water. This year's presentation expands upon that work. "A growing body of evidence suggests that the consequence of prenatal exposure to pesticides and nitrates as well as to other environmental contaminants is detrimental to many outcomes of pregnancy. As a neonatologist, I am seeing...

Hearts of male and female rainbow trout are different

Summary and Conclusions This study expands upon previous findings that sex differences in cardiac performance and metabolism exist in fish in general, and have now been found to occur in rainbow trout in particular. Moreover, the differences are only realized during working conditions and inv...

Study links faulty DNA repair to Huntington's disease onset

...that the disease progresses when the extra segment expands over time in non-dividing cells such as nerve cells." McMurrays study shows that the inserted segment grows when cells try to remove oxidative lesions, which are caused by byproducts of the oxygen we breathe. DNA repair enzymes initially keep oxida...

Discoveries thrust cancer-initiating stem cells into a larger role in cancer biology and treatment

...to self-renew, deregulation of either PTEN or HER2 expands the stem cell populations with self-renewing ability." According to Korkaya, cells with deregulated or increased self-renewing ability will then initiate and maintain tumors that are resistant to current therapies. The two genes appear to infl...

Where is the proton? Yale scientists discover footprints of shared protons

In it the researchers were able to look at how stiff the proton trap is between two molecules, and how this stiffness depends on the properties of the molecules to wh...

The Nature study expands on work on emotion and decision-making that Damasio began in the early 1990s and that caught the public eye in his first book, Descartes Error. Marc Hauser, whose behavioral work in animals has attempted to identify precursors to moral behavior, ...

Breakthrough vaccine to treat chemo-resistant ovarian cancer

... plans to launch a new cancer vaccine therapy that expands treatment options for thousands of women with advanced stage ovarian cancer. This innovative treatment will be offered by Cancer Treatment Centers of America and developed by AVAX Technologies, Inc. (OTCMarket: AVXT.OB). "Cancer Treatment Centers ...

Male reindeer inflate a large air sac in the neck region to emit their hoarse rutting calls

Simultaneously, the performance serves to attract female mating partners. Males vocalize almost exclusively dur...

"Habitat overlap, even without direct contact between people and primates, is sufficient for the exchange to occur." The further finding that humans had ...

New hope for regenerative medicine

Using mice that develop a disease very similar to T1D (NOD mice), Thomas Kay and colleagues showed that NOD mice that were unable to mount an immune response to proinsulin also had no immune cells that recognized a sec...
