Autism linked to mirror neuron dysfunction

...o understanding the neural basis of autism and may point the way to early diagnosis and to potential therapies. A first step, Ramachandran said, might be to test those individuals who seem to have a greater genetic likelihood of autism: the younger siblings of those already diagnosed. Though EEG is not a...

Researchers identify cause of 'early bird' sleep disorder

...milar clock-shift. Both arise because of so-called point mutations in the genes. This means that altering a single base-pair in the gene's long DNA chain is enough to change a person's sleep behavior. Evidence from tissue culture experiments with the second gene suggests the change causes a protein -- an e...

Searching the depths of the straits of Florida for disease cures

... miles away. Later, it became a notorious stopping point for narcotics smugglers, though regular patrols have all but eliminated that reputation. Though only about 50 miles from the Florida Keys, the Cay Sal Bank remains remote and relatively pristine because would-be visitors must clear customs on inhabit...

Cranberry juice modulates atherosclerotic vascular dysfunction

...eve the levels in the current study. However, the point to be emphasized is that total polyphenol intake is very low in western diets and a diet rich in polyphenols would in fact give a daily intake that is equivalent to the levels in our cranberry feeding experiments." Kruse-Elliott added: "We're lucky...

They will also point out the challenges facing research on aging, among them, determining which potential interventions and therapies could help us all improve our chances for a healthy, independent late life. Salerno will moderate the panel which will feature NIA Direct...

Growth disorder gene plays a big role in normal size variation

...A differences nearby. The results from this study point out an important feature of inheritance, namely, that a gene implicated in a Mendelian trait can also contribute to quantitative variation. While catastrophic expression failure, such as a loss of function, can cause disease, smaller changes in expre...

Where bacteria get their genes

...acquired genes get lost from the genome at a later point or, if they do persist, the bacteria then transmit them to their offspring. Being able to classify bacteria is crucial for medicine, Ochman said. "If you go to the doctor with strep throat he can be pretty certain that it's the result of an infection...

Furthermore,the authors point out, the elephant populations that have managed to survive live in areas where humans have never settled in large numbers. *"Neural Cliques" Create Real-Time Memories By simultaneously recording the activity of hundreds of neurons in live mice, res...

Scientists announce world's most sensitive cancer test

This allows laser beams strong enough to detect stretching to be used without killing the cell. "Of all the physical properties of a cell," explains Professor Ks, "...

Breakthrough isolating embryo-quality stem cells from blood

Cholesterol-regulating protein maintains fat-storage, fat-burning balance

From the point of view of evolution, an animal capable of linking its ability to sense cholesterol with its ability to store fat may have had a survival advantage. An adult mammal has virtually no need for dietary cholesterol because its body can synthesize enough ...

'Termite guts can save the planet,' says Nobel laureate

A world population of 9 billion, the predicted peak in population, could be fed with less than one third of the p...

Jeffrey Friedman, discoverer of leptin, receives Gairdner, Passano awards

These observations have reframed views on the pathogenesis of obesity and suggested that the development of approaches to improve leptin response in resistant individuals could provide new treatments for obesity. Leptin itself has proven...

Now scientists think you'd be 'roasted' in a black hole

...heard of the event horizon of a black hole, as the point of no return. But astronomically realistic black holes are more complex and should have two horizons, an outer and an inner. In the bizarre physics of black holes, time and space are exchanged when you cross an event horizon, but at a second horizon ...

It is exciting that this finding has been replicated and extended to a different population." Nonetheless, both Lappalainen and Edenberg pointed out that possessing...

Report proposes structure for national network of cord blood stem cell banks

The point at which the costs of banking cord blood exceed the benefits for the patient population is 200,000 units, according to an economic analysis conducted for the study. Cord blood banks should strive to provide units with a high-enough concentration of ...
