Better sleep may put Huntington's disease sufferers back on track

...-term implications for treatment of HD and for the reversal of the diseases impairments. Recognising that sleep disturbance is a part of the disease means that clinicians should include focussed management of sleep symptoms in their treatment of HD patients....

Loss of cell's 'antenna' linked to cancer's development

Exercise reverses aging in human skeletal muscle

...th age. However, exercise resulted in a remarkable reversal of the genetic fingerprint back to levels similar to those seen in the younger adults. The study also measured muscle strength. Before exercise training, the older adults were 59% weaker than the younger adults, but after the training the strength of...

Alarming acceleration in CO2 emissions worldwide

...reases in energy and carbon intensity constitute a reversal of a long-term trend toward greater energy efficiency and reduced carbon intensities. Despite the scientific consensus that carbon emissions are affecting the worlds climate, we are not seeing evidence of progress in managing those emissions in eithe...

Oregon researchers involved in new Clovis-age impact theory

... questions. The researchers propose that a known reversal in the world's ocean currents and associated rapid global cooling, which some scientists blame for the extinction of multiple species of animals and the end of the Clovis Period, was itself the result of a bigger event. While generally accepted theor...

Reversing cancer cells to normal cells

...odel - where inhibiting Nodal signaling led to the reversal of the melanoma cells to a more normal cell type. This is a promising area of research, says Dr. Hendrix. The discovery of a new signalizing pathway in melanoma and other tumor cell types and the ability to inhibit Nodal and thus reverse the melan...

...ssure in parts of the Arctic Ocean indicate that a reversal of the polar oceans circulation may be under way. The spatial distribution and magnitude of these trends suggest a shift from a clockwise to a counterclockwise pattern prevalent prior to the 1990s. Changes in Arctic Ocean circulation are important to...

New test predicts blood cancer's sensitivity to experimental cancer drug

...incurable disease, are vulnerable to this dramatic reversal of fortune because they are "primed for death;" they are surviving only because Bcl-2 proteins are blocking powerful cell-death molecular signals by holding them hostage. Primed cells, Letai explained, are like a car with a revved-up engine on the ed...

With a feminine fruitless gene, male flies adopt more ladylike tactics, mostly the head butt and some shoving. With the masculine fruitless gene, females instinctively lunge to the exclusion of the...

Pressured by predators, lizards see rapid shift in natural selection

Says Mr. Ausubel: "This great reversal in land use could stop the styling of a Skinhead Earth and begin a great restoration of the landscape by 2050, expanding the global forest by 10 percent about 300 million hectares, the area of India." "Without depopulation or impoverishment, incre...

Resistance to chemotherapy in lung cancer, optimizing flu vaccination strategies

The level of transmissibility at which this reversal occurred depended on several factors, including whether vaccination was delayed and how many times influenza was introduced into the community. Meyers and colleagues tested their models by checking that they could replicate real influenza epidemics...
