Young Blood Revives Aging Muscles, Stanford Researchers Find

...le's fault. A study in the Feb. 17 issue of Nature shows that it's old blood that keeps the muscles down. The study, led by Thomas Rando, MD, PhD, associate professor of neurology and neurological sciences at the Stanford University School of Medicine, built on previous work showing that old muscles have ...

At the molecular level, the predator is the prey

...d amounts of expression. The current Nature report shows that snakes' ability to detoxify TTX involves changes in the sodium channel gene. "That is generally the story as it is developing," Brodie said. "Ecological arms races that go on between predator and prey are really driven at the molecular level. W...

Embryonic Stem Cells Treated With Growth Factor Reverse Hemophilia In Mice: UNC Researchers

...and immunology. "The data published in this study shows that embryonic stem cells partially differentiated, are able to remain in the liver and be functional without apparent immunological rejection. This transforms them into possible candidates for cellular transplantation into the liver." Along with Fa...

Atmosphere may cleanse itself better than previously thought

...ules as well. "This study is important because it shows that the atmosphere could be generating far more OH radicals than we thought before because the models are underestimating the amount of chemistry that’s happening," said Sinha, who is an associate professor of chemistry and biochemistry. "It could i...

Scientists find viruses can't stick to sea bugs in the dark

...al Microbiology's 156th Meeting in Scotland, which shows that these cyanophages depend on light to stick to their victims, and cannot function in the dark. "Understanding the function of light as one of the most important environmental factors of the phage-cyanobacteria interaction is vital," says Ying Jia...

Life detection instrument passes key test on road to Mars

...ed now, thanks to the work of NASA and others that shows there used to be running liquid water on the surface of Mars." "The connection between water and life has been made very strongly, and we think there is a good chance there is or was some life form on Mars," Mathies said. "Thanks to Alison's work, w...

Research may provide new link between soft drinks and weight gain

...rate in a way that favors fat storage. "Our study shows how fat mass increases as a direct consequence of soft drink consumption," said Dr. Tschöp. The research appears in the July 2005 issue of Obesity Research, the official journal of the North American Association for the Study of Obesity (NAASO). Co...

Census of Marine Life explorers surprised by diversity, density of Arctic creatures

...The imagery obtained of the mid-water and seafloor shows many life forms, such as soft bodied zooplankton, deep sea cucumbers and soft corals. The few explorers in this area before us had no adequate tools to collect or see these creatures. "What continues to fascinate and motivate us all is the chance to...

Community MRSA is re-emergence of 1950s pandemic, study suggests

...ins why 1950s pandemic was so successful, but also shows why community acquired MRSA could pose such a serious public health challenge in coming years. "The community acquired MRSA clone has a toxin and other traits with a proven track record for causing serious diseases in healthier and younger age group...

Ancient DNA helps clarify the origins of two extinct New World horse species

...ross the Bering Strait, the new PLoS Biology study shows that the American and Eurasian horses' genomes are too distinct for this theory. "We found that the stilt-legged horse in North America was in fact a home-grown endemic, and had just converged morphologically, probably due to shared environments," Co...

Critical step traced in anthrax infection

...ng effort to produce a better anthrax therapeutic, shows that the protective antigen component of the bacterial toxin plays an active role in transferring the other two components of the toxin through the cell membrane. The research, led by R. John Collier, professor of microbiology and molecular genetics...

Team Invents Device For Weighing Individual Molecules

..., the technology his group has announced this week shows the immense potential of nanotechnology for creating transformational new instrumentation for the medical and life sciences. The new devices are at the nanoscale, he explains, since their principal component is significantly less than a millionth of ...

UN pours polio vaccine into Yemen amid outbreak

Enzyme's newly discovered role may make it target for arthritis treatment

...hington University School of Medicine in St. Louis shows that an enzyme known as cathepsin G regulates the ability of immune cells known as neutrophils to secrete chemicals that attract other immune cells and start the local inflammatory process. Over time, the excessive accumulation of immune cells can le...
