Too much water may be as dangerous as too little during long-distance athletic events

.... Levine said. "It's also good to accept some mild dehydration during a long race. There are plenty of Web sites available now that show how to customize your fluid intake." He also added that taking along salty snacks to eat during the race is a good way of combating hyponatremia. Generally, athletes of all ty...

Bush, Cheney and Rumsfeld are now species of slime-mold beetles -- but strictly in homage

Evidence of 600-million-year old fungi-algae symbiosis discovered in marine fossils

...gainst dehydration. But in the marine environment, dehydration is not an issue and the 600-million-year-old rocks also contain many fossils of coccoidal cells that are not surrounded by filaments. "So it is a loose lichen-like association," said Xiao. "The organisms are not obliged to live together." Now there ...

Spiders help scientists discover how muscles relax

...echniques. Standard electron microscopy requires dehydration and staining of a tissue sample, which modifies the structure of the specimen and distorts its shape. Cryo-electron microscopy avoids these problems by rapidly freezing the sample. Using the new technique, the researchers were able to visualize the m...

A new molecule discovered in the battle between plants and disease

...itoring expression of the proAtPep1 gene. Cold and dehydration stress and exposure to ABA or MeSA did not affect the expression of proAtPep1, but wounding, exposing plants to methyl jasmonate (MeJA), or supplying plants with the AtPep1 peptide through cut petioles induced expression of the gene. Also expressed i...

Newly recognized gene mutation may reduce seeds, resurrect plants

...siologist. Lipids play a role in preventing plant dehydration in forming cells' membranes, in molecular signaling and in energy storage. A still-to-be revealed lipid associated with formation of the cuticle that coats plant surfaces may signal whether a seed develops to maturity or is aborted early due to a def...

Slow-frozen people? Latest research supports possibility of cyropreservation

...ar and intra-cellular ice formation which leads to dehydration and separation into the ice and concentrated unfrozen solution. If we could, by slow cooling/warming, supercool and then warm the cells without the crystallization of water then the cells would be undamaged." ...

Novel therapy combinations gain ground in treating hepatitis

...ough has been seen to date. However, vomiting and dehydration requiring hospitalization occurred in three patients taking the highest dose (800 mg), forcing the research team to halt the use of that dose and continue using only the lower doses of 200 to 400 mg of the drug. "For patients whose disease has not r...

For many insects, winter survival is in the genes

...during exposure to high levels of toxic chemicals, dehydration and even desiccation," Denlinger said. He and his colleagues first figured out how many genes were turned on only during the flesh fly's dormant state. The researchers extracted and compared RNA from both dormant and non-dormant fly pupae – the de...
