Helping chlorine-eating bacteria clean up toxic waste

...hers, and nobody knows for sure why. In fact, very little is understood about how these organisms live and breathe. Normal laboratory procedures haven't provided enough answers, because the bacteria are hard to grow in a petri dish, said Ruth Richardson, Cornell assistant professor of civil and environmenta...

Definitive evidence found of a swimming dinosaur

...een researched for years. Until now, however, very little hard evidence existed documenting the behavior. Several earlier discoveries were later found to have been produced on dry ground or categorized as ghost traces, possible undertracks preserved in lower layers of sediment. "The trackway at La Virge...

How plague-causing bacteria disarm host defense

...sis and Y. enterocolitica are big words for nasty, little bugs that cause what's commonly known as food poisoning. All three bacteria species find their way past the body's immune system through a sophisticated invasion system that injects the effector proteins directly into the host cell's cytoplasm. "...

Experimental gene therapy 'abolishes' arthritis pain and lessens joint damage

...eeded for powerful pain relief," Tallents said. "A little further out, the new idea that peripheral inflammatory diseases like arthritis can lead to brain inflammation may provide an entirely new way to treat inflammatory neurological conditions that affect millions."...

Madagascan tropical forests return thanks to better management and well-defined ownership

...n which tropical forest loss is embedded, but very little is known about the role of social institutions in influencing regeneration of tropical forests," says Maria Tengö from Stockholm university and one of the authors behind the new study. The new study points to the large capacity of dry tropical for...

Does amateur boxing cause brain damage?

...t of professional boxing, until now there has been little information on the possible risks for brain injury in amateur boxing," said study author Max Hietala, MD, PhD, with Sahlgrenska University Hospital, Goteborg, Sweden. For the study, researchers used lumbar puncture to determine if there were eleva...

Scripps research team sheds light on long-sought cold sensation gene

...avior," he says. The altered mice also showed little response to the application of acetone to their hindpaw, which causes an unpleasant cold sensation, while the acetone caused normal mice to flick their paw and lick them. TRPM8 codes for an ion channel found at the tips of sensory neurons, which i...

Climate change impacts stream life

...orm important links with surrounding habitats, yet little emphasis has been given so far to the ecological effects of climate change on these running-waters. Now a twenty-five year study at Llyn Brianne in central Wales, led by Professor Steve Ormerod and Dr Isabelle Durance of the Cardiff School of Bi...

Keeping the immune system from starting a 'food fight'

... they said. "Humans were not meant to deal with little to no exercise and a constant bombardment of nutrients," said Gökhan Hotamisligil of the Harvard School of Public Health of his team’s findings. "If we could find ways to strengthen STAMP2 or prevent its suppression, the body might retain control," e...

Traumas like Sept. 11 make brains more reactive to fear

...ent at Cornell. "Up until now, there has been very little evidence of that." Using functional magnetic resonance imaging to see how people's brains responded to photographs of fearful versus calm faces, the scans of 11 people who were within 1.5 miles of the World Trade Center on Sept. 11, 2001, were comp...

Scientists: As rainfall changes, tropical plants may acclimate

...ropical plants are highly specialized in their own little environmental niches ?and thus very sensitive to disturbances of those niches. That could be good for the plants because climate change is expected to radically alter rainfall patterns in the tropics. But it comes with a caveat: Nutrient uptake is...

LIAI scientists make important finding on cytomegalovirus transmission

...e majority of the world’s population, but produces little or no symptoms in healthy individuals. However, it can cause multi-organ disease in newborns or persons who are immuno-compromised such as organ transplant recipients or AIDS patients. Ware said, "The main importance of these experiments is ident...

Latent memory of cells comes to life

Mechanisms at the origin of this so-called cellular differentiation are those for which researchers at the University of Copenhagen have a possible clarification. ”The explanation for the s...

Hives ferment a yeasty brew, attract beetle pest

...e small hive beetles are common in Africa and pose little threat to African honeybee hives, it appears that domesticated European honeybees have a much harder time containing the beetles in their hives. European honeybees were bred to be docile and easy to work with, while African honeybees are noted for ag...

Discovery of 'master switch' for the communication process between chloroplast and nuclei of plants

...ext of the plant’s stress response. It will take a little more tweaking, but at least knowing that it is going through a certain particular pathway will enable researchers to design what the targets should be downstream from these pathways." Work for the project was supported by a grant from the Department ...

In Iran, cheetahs collared for the first time

Understanding their movements as they travel between reserves is one of the first steps in establishing a plan to secure and connect t...
