Bisexual fruit flies show new role for neurochemical

...t use glutamate to send messages because there was too much glutamate background noise in the brain. It turns out that this background noise plays an important part in regulating information transfer." Featherstone and his lab team found that glia cells are the source of the excess ambient glutamate. A...

Newborn brains grow vision and movement regions first

Bacteria control how infectious they become, study finds

... coli are caught in a delicate balancing act. With too little RfaH, bacteria grow too slowly. But too much RfaH, and they will die. While RfaH's control over gene expression is limite...

Trusting your instincts leads you to the right answer

...re more likely to perform well if you do not think too hard and instead trust your instincts. The research, published online today in the journal Current Biology, shows that, in some cases, instinctive snap decisions are more reliable than decisions taken using higher-level cognitive processes. Particip...

Insomnia drug can improve brain function

...t occurred due to oxygen deprivation may have been too severe to allow spontaneous speech. They conclude that single patient trials can be a logical approach to identifying potentially beneficial drugs, especially in the case of rare or orphan diseases. ...

Turning green gunk to gold, anti-cancer gold

...to gold---cancer fighting gold. "It was simply too difficult to use the native blue-green algae for high-level production using traditional fermentation approaches," said Sherman. But the compound, called cryptophycin 1, held so much promise as an anti-cancer drug that organic chemists got busy tryin...

'Night owls' report more insomnia-related symptoms

...iculty falling asleep or staying asleep, waking up too early, or poor quality sleep, is the most common sleep complaint at any age. About 30 percent of adults have symptoms of insomnia. The amount of sleep a person gets affects his or her physical health, emotional well-being, mental abilities, produ...

Tumor-suppressor gene is critical for placenta development

... progenitor cells. These stem cells divided far too often. They gave rise to too many cells and formed a defective placenta, especially where the placenta interacts with the uterus....

UW launches study testing adult stem cells for heart damage repair

...ries of mini-heart attacks that, while they may be too small to notice at the time, in aggregate cause significant long-term damage to the heart muscle and disability to the patient. While cardiologists can restore blood flow in some cases, the heart muscle can be irreversibly damaged, leading to signif...

Putting an old drug to a new use

...now that iron deficiencies are dangerous, but also too much iron is bad for our health. Our body stores e... the metal can lead to dangerous anemias, but also too much iron can be detrimental as iron promotes the formation of toxic radicals leading to tissue dama...

New molecular pathway could reveal how cells stick together

... identified previously," Page-McCaw said. But it's too soon to know how her findings will be used in terms of human health. "There are lots of examples of times where the ability of cells to communicate goes awry in disease and ninjurin could be playing a role in any of those," she said. "The goals of...

New study may show how to forestall a fatal, virus-caused immune-system meltdown

...mes the most dangerous element of the disease. All too often, a sudden immune overreaction sends the infected person into a shock-like state from which he or she may never recover. Now, researchers at the University of Texas Medical Branch at Galveston (UTMB) believe they’ve found a way to spot the bi...

Study identifies risk factors for spread of respiratory infections in hospitals

... This new study suggests that hospital beds placed too closely together, hospital staff working while having symptoms of SARS, and the use of oxygen therapy were the most significant risk factors associated with the spread of SARS in 26 hospitals in Guangzhou and Hong Kong. These findings have implic...

Exploring the molecular origin of blood clot flexibility

..., problems with bleeding arise, and when clots are too stiff, there may be problems with thrombosis, which results when clots block the flow of blood. First author André Brown, a physics graduate student at Penn, notes that this research is a first step towards understanding the mechanics of the relation...

Researchers create artificial enzyme that mimics the body's internal engine

...n a Western movie." But the electrons are consumed too fast to study individually, he noted. Therefore, the researchers had to invent a technique that supplied electrons to their enzyme model in a slow and continuous way. They solved the problem by attaching the model to a liquid crystalline film on a go...

Warming oceans threaten Antarctic glaciers

... the research shows that its glaciers are changing too erratically to establish a trend with confidence. In contrast, four major glaciers in East and West Antarctica were shown to be retreating in unison, raising concerns that global sea level could rapidly rise if the oceans continue to warm. Dr. And...

Cancer tip -- Nanoparticles can damage DNA, increase cancer risk

...late from the larger environment, as they are much too small for removal by conventional filtering techniques. When nanoparticles find their way into cancer cells, they can wreak havoc, according to Sara Pacheco, an undergraduate researcher at the University of Massachusetts. Yet very little is know...

Racing neurons control whether we stop or go

Growth hormone is not the anti-aging bullet for healthy adults

...y, you might get that change without breaking into too much of a sweat, and you wouldn't spend $1,000 to $2,000 a month on something that appears to have modest or minimal benefit and the probability of bad side effects," said Liu. ...

Sleep disturbances affect classroom performance

...acurricular activities at school are proving to be too time-consuming, consider cutting back. If you are not asleep after 20 minutes, then get out of the bed and do something relaxing, such as reading a book or listening to music, until you are tired enough to go back to bed. Get up at the same tim...
