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 i...

Study of high-pressure process to inactivate Norwalk virus underway

...ong-term effects. The disease is rarely fatal, but dehydration can become dangerous in rare cases. In the United States, most outbreaks are linked to consumption of raw oysters and clams, contaminated water, raw salads, and ready-to-eat foods. Noroviruses are resistant to detergents, solvents, high temperatures...

APS oxytocin/vasopressin conference: 13 highlighted presentations

...n of eating and digestion, found OT contributes to dehydration inhibiting food intake in mature rats and mice, but not baby rats. Plus, 'dehydration anorexia' is absent in OT-null mice who ate regularly when dehydrated, indicating OT is key signaling peptide in hypothalamic control of adaptive responses to dehyd...

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...

Spiders help scientists discover how muscles relax

...techniques. 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...

Dark chocolate helps diarrhea

...dren or elderly patients with diarrheacan die from dehydration within a few days. History shows that the use of cocoa to treat diarrhea dates back to the16th century by ancient South American and European cultures. Until now,no one knew exactly why the cocoa bean appeared to be a remedy. "Ourresearch successful...

Newly recognized gene mutation may reduce seeds, resurrect plants

...ysiologist. 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...

...ry. Caffeine can cause restlessness, irritability, dehydration or heart arrythmias, and those who are highly sensitive to caffeine can feel its stimulant effects for as long as 20 hours. In addition, some medicines adversely interact with caffeine. "We believe our test would be the first consumer test for caffe...

Slow-frozen people? Latest research supports possibility of cryopreservation

...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."...

UCLA researchers discover new disorder that causes chronic diarrhea in children

...who each showed symptoms of vomiting, diarrhea and dehydration during the first few weeks of life, following consumption of formula. Researchers used genomic DNA from the patients to screen for mutations of NEUROG3. They then tested the ability of the mutations to alter NEUROG3's function. Martn anticipa...

High-value chemicals produced from ethanol feedstocks could boost biorefinery economics

Research aimed at producing high-value products from cellulose feedstocks is being done through the "AtlantIC Alliance," a coalition of three research institutions in the United States and the United Kingdom. The alliance,...

Study challenges belief that tree frogs depress metabolic rate after 'waxing' themselves

"Our data do not provide strong evidence that P. hypochondrialis routinely depress metabolic rates and enter a deep dormant state during quiescent behavi...

Natural anti-freeze -- how arthropods survive the cold

...chiurus arcticus (from the Arctic) uses protective dehydration to survive harsh Arctic winters. This means that water is lost from the body across a diffusion gradient between the animals super-cooled body fluids and ice in the surroundings. "During this process the body loses all its water and you end up with a...

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 deve...
