Deep sleep short-circuits brain's grid of connectivity

...e in the UW Psychiatric Institute and Clinics, may aid in the development of diagnostic and therapeutic tools for neurological and psychiatric disorders that affect consciousness, such as schizophrenia. That work is now being pursued by the Wisconsin group. In addition to Tononi and Massimini, co-author...

Researchers feed tiny pills of RNA to planarians to identify genes essential for regeneration

...es in the process, the U researcher predicts, with aid of the planarian, more discoveries are on the way. "Our limitations right now are how many experiments we can do in a day," he said. "The mystery of what makes regeneration possible, particularly in these animals, is on its way to finally being reso...

International Team Determines Geographic Origin of Leprosy

...tely treated and has returned. This, in turn, will aid efforts to fully treat patients so that the bacteria are completely eliminated. Reference: M Monet et al. On the origin of leprosy. Science 308 (2005) DOI: 10.1126/science.1109759. ...

When it comes to cell entry, being average has its advantages

...olve clathrin, a protein that coats the invader to aid in the Velcro-like fastening. Yet scientists have shown that flu viruses can invade cells even without a clathrin coat. Along with Huajian Gao and Wendong Shi from Max Planck, Freund created a mathematical model that can account for this. Particle si...

Hopkins AIDS experts issue warning about global efforts to provide drug therapies

..., despite the generous nature and growing scope of aid efforts." While President Bush's 2003 Emergency Plan for AIDS Relief is spending more than $600 million on antiretroviral therapies for 2 million people, demand in the developing world is even greater and steadily growing, with at least 6.5 million ...

Experiment station researchers to explore genome of disease-fighting fungus

...s involved in inducing plant resistance could also aid the greenhouse industry that encounters problems with seedling rot in different plant varieties. "In the nursery industry where you transplant from smaller to larger containers, you can incorporate the fungus as a potting mix amendment that would pr...

Researchers test new therapy for advanced melanoma

...sing new therapy that prompts the immune system to aid in the fight against melanoma tumors. "This is a milestone clinical trial because it is the first time that electroporation is being used to deliver plasmid DNA in a gene therapy study in humans," said Richard Heller, PhD, USF professor of medical m...

Two new retroviruses—transmitted from animals—identified

...ease ?a task exceptionally challenging without the aid of robotic technology. In the second study, the surgeons performed a variety of surgical procedures on a human cadaver. They concluded that robotic surgery may shorten operating time and allow for minimally invasive treatment of more cancer patients...

Alcohol consumption disrupts breastfeeding hormones

...ing women have been advised to drink alcohol as an aid to milk production and optimal lactation. Recent surveys indicate that 25% of women report being encouraged by their health professionals to drink alcohol while breastfeeding. But as Mennella points out, "There was no valid scientific evidence to sup...

NHGRI targets 12 more organisms for genome sequencing

...ornis, will be sequenced at less dense coverage to aid in the comparative studies. Sequencing efforts will be carried out by the five centers in the NHGRI-supported Large-Scale Sequencing Research Network: Agencourt Bioscience Corp., Beverly, Mass.; Baylor College of Medicine, Houston; the Broad Institu...

Six million Africans face famine because of locusts, drought

...apsoba said. "The people in these areas need food aid and help to re-launch their own farming efforts in the form of fertilizer and other inputs for the coming planting season." In some areas of Mauritania, northern Senegal, Mali, Burkina Faso, Niger and Chad, the prices of food, especially millet, hav...

To control germs, scientists deploy tiny agents provocateurs

...e, biofilms can coat plant roots and symbiotically aid ecological processes such as nitrogen fixation. But at the darker end of the scale, biofilms can form infection-inducing layers on implanted medical devices and cause deadly lung infections in cystic fibrosis patients. Biofilms have long baffled rese...

Scientists discover how plants disarm the toxic effects of excessive sunlight

... and the treatment of human and plant disease, and aid the effort to create alternative bioenergy sources," Donohue says. Donohue and his group studied a photosynthetic microbe and identified the cellular pathways it used to sense the presence of singlet oxygen and defend itself from this toxic substanc...

New component of the 'brakes' on nerve regeneration found

... that encases neurons and acts as an insulator and aid to the transmission of nerve impulses. Researchers knew that CNS neurons had receptors on their surface that accepted the inhibitory molecules--like a key fitting a lock--and switched-on inhibitory signaling within the neuron. They had also shown th...

UCLA launches $20 million stem cell institute to investigate HIV, cancer and neurological disorders

Bird Brains Show How Trial and Error May Contribute to Learning

...them. The systematic trials were possible with the aid of a computer program that could track the bird twitters and trigger stimulations to LMAN at precise moments to elicit measurable effects on a predetermined syllable, song after song. The researchers found that different areas of LMAN tuned the same...

NJIT Presidential Award winner takes stem cell research another step

... breakthrough focused on developing scaffolds that aid stem cells. She performed animal studies on rats with bone defects; she also did cell-culture studies. Both showed that the biomaterials stimulated stem cells, producing new bone tissue and fully repairing the rats' bones. Arinzeh's second stem-cell...

First real-time view of developing neurons reveals surprises, say Stanford researchers

...ow from the eye to reach the brain. Then, with the aid of a 6-foot-long laser and some fancy microscopy, the researchers were able to watch individual neurons as they matured in real time. The pair specifically monitored hundreds of neurons in the region of the brain that respond to images. Niell set up...
