Wisconsin researchers identify sleep gene

... getting from the faster to the slower state is by opening ion channels, allowing potassium to flow through them. "Our hypothesis is that if you don't have potassium channels, you won't get slow waves," Cirelli says. "The cell membrane will remain activated, preventing long periods of deep, non-REM sleep." ...

Discovery Promises Simpler Therapy for Sickle Cell Disease

...anes might therefore prevent the disease symptoms, opening up a new realm of therapeutic possibilities, Stamler said. Current therapies fail to treat the disease itself and are instead geared toward minimizing pain and preventing infection, he added. In patients who become anemic, blood transfusions replenis...

NASA study finds snow melt causes large ocean plant blooms

...656 to 3,281 feet). Since the Arabian Sea lacks an opening to the north, the deeper waters are not well ventilated. Also when organic matter produced by phytoplankton breaks down and decomposes, more oxygen gets consumed in the process. An increase in phytoplankton could therefore cause oxygen deficiencies i...

Remote control flies? Fly behavior controlled by laser light

...cape movements--extending their legs, jumping, and opening and rapidly flapping their wings. The laser-triggered remote controls in the giant fiber system worked about 63 percent of the time, while remote controls placed in other nerve cells that were targets of the giant fiber system worked 82 percent of t...

Researchers test new therapy for advanced melanoma

... to open up pores in the tumor cell membrane. This opening allows a small therapeutic molecule -- in this case a molecule known as a DNA plasmid that contains the gene for Interleukin-12 -- to slip inside the melanoma tumor before the membrane reseals. "Melanoma does not respond well to standard chemotherap...

Scientists use manufacturing methods to reconstruct mastodon

Once the exhibit opening is behind us, I hope to be able to concentrate more on the interpretation of this animal's history and what it can tell us about late Pleistocene events." Leading up to the exhibit opening, the museum is offering a semester-long series of public edu...

The making and breaking of microtubules

"We found acetylation at this site near the entry-exit points of the DNA superhelix as it wraps around the nucleosome is required for recruiting the nucleosome remodeling complex SWI/SNF and so regulates gene act...

Going To Extremes To Improve Human Health

... when exercising," Minson explained. "It's already opening up new realms for our research mission." One example of the chamber's potential is enhancing researchers' ability to explore fatigue. "Physical and mental fatigue may not be commonly perceived as work hazards, but fatigue often is a fundamental caus...

Micro-molecule plays big role in birth defects

...es at any stage in the developmental process, thus opening a window into the role of microRNAs in limb development. In cases where Dicer is not present in developing limb tissue, Harfe showed that microRNAs were not processed and limbs were visibly smaller. "Many of the birth defects we see in people are m...
