How the neuron sprouts its branches

...eir neighbors. Dendritic connections are the basic receiving stations by which neurons form the signaling networks that constitute the brain's circuitry. Such basic insights into neuronal growth will help researchers better understand brain development in children, as well as aid efforts to restore neuronal c...

Worms know bad food when they smell it

...ch as that associated with chemotherapy. Patients' receiving chemotherapy experience intestinal damage, which sends a serotonin signal to the brain that triggers nausea. "People who are getting chemotherapy are told 'eat only bland foods -- don't eat foods you really like because you won't be able to eat them ...

...atform in seven days; the NF1 mice took 10. After receiving statins, the NF1 mice outraced the normal mice. Third, Lee tested coordination by training the mice to balance while running on a rotating log, which gradually increased in speed. At first, the NF1 mice would jump off as the log spun faster. ...

New brain scan technology could save babies' lives

... image. This can show which parts of the brain are receiving oxygen, where blood is situated, evidence of brain damage etc. MONSTIR is the size of a fridge-freezer and takes around 8 minutes to generate an image. The aim is to produce a version that is half this size, 5 times faster, even more accurate and g...

Clinical trial to test stem cell approach for children with brain injury

...ment effect," Cox said. Because the children are receiving their own cells, an immunological response to the treatment is unlikely. Even marginal improvement could mean a great deal to someone who suffers a brain injury. "It could be the difference between being able to recognize your loved ones and not b...

Katrina floodwaters not as toxic to humans as previously thought, study says

...uate the flood's impact on Lake Pontchartrain, the receiving body for the pumped floodwaters. The researchers found high levels of bacteria, most likely from fecal contamination resulting from sewage. Levels were within the range of typical storm-water runoff in the city, the scientists say. They also detecte...

New class of antibiotics effective against drug-resistant bacteria discovered in fungi

...surprising finding from water samples from streams receiving runoff is that low concentrations of arsenic are transported to streambeds instead of being retained by the aquifers, Schreiber said. "We think that the arsenic is adsorbed onto nanoscale particles that pass though our filters and through the soil co...

Geoscientists follow arsenic from chicken feed to streambeds

Reducing antibiotic use lowers rates of drug-resistant bacteria

..., pharmacists, parents, and children in the groups receiving both interventions with an information campaign about antibiotic resistance and appropriate antibiotic use. A control group of children and their doctors received no specific information about antibiotic use. The study was conducted from January thr...

HIV mortality in India drops with introduction of generic antiretroviral therapy

...ised patients, occur at a much lower rate in those receiving ART and its highly active drug counterpart, HAART. Accessible drugs have led, in part, to an 80 percent decline in HIV-related deaths in India between 1997 and 2003. Despite ART's importance in improving HIV-infected people's health, it can also cau...

Grabbing addiction by the tail

...amate. "This is the 'go' signal," said Wang. "The receiving cell uses glutamate receptors on its surface to listen to the signal. But after repeated abuse of a drug, cells in the nucleus accumbens internalize glutamate receptors, compromising their ability to listen to the signals. Earlier research showed th...

Neurons adjust the strength of those connections adaptively, to amplify or suppress connections.
