Carbs Are The Fuel Of Choice At High Altitude
2012-12-07 13:13:53

Cell Press Mice living in the high-altitude, oxygen-starved environment of the Andean mountains survive those harsh conditions by fueling their muscles with carbohydrates. The findings, reported online on December 6 in Current Biology, a Cell Press publication, provide the first compelling evidence of a clear difference in energy metabolism between high- and low-altitude native mammals. "The high-altitude mice we examined in this study are a rare exception to a general exercise fuel use...

Yeast Mothers Sacrifice All For Their Babies
2012-11-09 10:28:33

University of California - San Francisco UCSF discovery shows evolution at work in the laboratory A mother's willingness to sacrifice her own health and safety for the sake of her children is a common narrative across cultures — and by no means unique to humans alone. Female polar bears starve, dolphin mothers stop sleeping and some spider moms give themselves as lunch for their crawly babies' first meal. Now an unexpected discovery at the University of California, San...

Promising Therapy For Huntington’s Disease Developed
2012-11-01 15:43:50

Lawrence Berkeley National Laboratory Initial results in mice could lead to new way to fight neurodegenerative diseases There´s new hope in the fight against Huntington´s disease. A group of researchers that includes scientists from the U.S. Department of Energy´s Lawrence Berkeley National Laboratory (Berkeley Lab) have designed a compound that suppresses symptoms of the devastating disease in mice. The compound is a synthetic antioxidant that targets mitochondria, an...

Lee Rannals for redOrbit.com — Your Universe Online Boosting the activity of a particular enzyme can help block tumors from growing, according to research published in Nature Chemical Biology. Cancer cells use up most of their energy by reproducing themselves, but in order to do this they must produce new cellular building blocks like DNA, carbohydrates and lipids. Biologists found that jacking up the activity of the enzyme pyruvate kinase can disrupt the production of tumors...

Researchers find that optimal length of mitochondria in neurons is essential to preventing onset of Alzheimer's and other tau-related diseases Goldilocks was on to something when she preferred everything "just right." Harvard Medical School researchers have found that when it comes to the length of mitochondria, the power-producing organelles, applying the fairy tale's mantra is crucial to the health of a cell. More specifically, abnormalities in mitochondrial length promote the...

A laboratory study led by UNC medical oncologist Stergios Moschos, MD, demonstrates how a new targeted drug, Elesclomol, blocks oxidative phosphorylation, which appears to play essential role in melanoma that has not been well-understood. Elesclomol (Synta Pharmaceuticals, Lexington, MA) was previously shown to have clinical benefit only in patients with normal serum lactate dehydrogenase (LDH), a laboratory test routinely used to assess activity of disease. For more than 60 years,...

Possible Tool To Study Aging From “Selfish” DNA In Animal Mitochondria
2012-08-10 09:14:10

Researchers at Oregon State University have discovered, for the first time in any animal species, a type of “selfish” mitochondrial DNA that is actually hurting the organism and lessening its chance to survive — and bears a strong similarity to some damage done to human cells as they age. The findings, just published in the journal PLoS One, are a biological oddity previously unknown in animals. But they may also provide an important new tool to study human aging,...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
