MIT's ocean model captures diversity of underwater forests

...onvey the diversity of phytoplankton, they did not well represent the systems they modeled. The new model remedies that. "Now we are finally modeling the ocean systems in a way that is consistent with how biologists think of them-water filled with millions of diverse microbes that wax and wane in rela...

NIAID expands capability for influenza research and surveillance

... and lessening the impact of seasonal influenza as well as an influenza pandemic. “The threat of an influenza pandemic is a major source of concern for the public health community,?says NIAID Director Anthony S. Fauci, M.D. “The new NIAID Centers of Excellence for Influenza Research and Surveillance will...

Researchers wake up viruses inside tumors to image and then destroy cancers

... says. "Velcade is only one of an array of new, as well as older agents, that can induce lytic infection, and a particular agent could be tailored for use in a specific patient through imaging," he says. ...

Discovery of new cave millipedes casts light on Arizona cave ecology

...ia. "Western U.S. caves have not been at all well explored for examples of cave life" Shear said. "We can expect more new species from the ongoing work at Northern Arizona University." This new genus was confirmed by analysis of the eighth pair of legs (or gonopods) on the male specimens. Gonopo...

Corals that can fight global warming may one day help fragile reefs

...ers cause increased virulence of some pathogens as well as a diminished ability of corals to fight them. But these complications can also be keys to coral reef survival. "A first line of defense is provided by surface microorganisms ?[that] produce antibiotics that can help corals fight pathogenic bacte...

Whiteflies and plant viruses can help each other to speed up biological invasion

...both invade and displace indigenous whiteflies, as well as causing disease pandemics of the viruses associated with this vector." The study also shows that infection of the whiteflies per se has limited effects on the survival and fecundity of the vectors, and the B whitefly acquires the benefits throu...

In young mice, gregariousness seems to reside in the genes

Ramamoorthy was awarded support from the National Institutes of Health and the National Science Foundation, through an NSF F...

Researchers develop marker that identifies energy-producing centers in nerve cells

...t leads to Alzheimer's and Parkinson's disease, as well as changes in the brain associated with stroke and aging. "Prior to the development of this marker, we had no way to identify the mitochondria in neuronal cells from those in glial cells," says the study's principal investigator, Krish Chandrasek...

Investigating the measles virus as a tool to kill multiple myeloma

... early evidence of activity against the cancer, as well as demonstrated safety. The team can now move to administration of higher and potentially even more potent viral doses. The glioblastoma multiforme trial, which opened in the fall, is testing the safety of another strain of the measles virus for trea...

Genetic fingerprints identify brain tumors' origins

...gerprints or bar codes for the location of PAs, as well as for another glial cell tumor called an ependymoma. In addition, scientists also detected these distinct patterns of expression in normal glia and stem cells from these brain locations, suggesting that genetic fingerprints can be used to identify t...

Cure for cancer one step closer

...rrow's cancer patients," he said. Queensland is well placed as a source of cancer tissue due to its diverse population, large number of aged retirees, and high-rate of some cancers, particularly melanoma. The Wesley Hospital alone had almost 2000 cancer related surgeries in 2004. The Queensland Gove...

30+ AIDS vaccine clinical trials in 24 countries, research occurring on every continent

...e hope to begin to see even more novel vectors, as well as approaches that target neutralizing antibodies in the next few years," said CEO and President of IAVI, Dr. Seth Berkley. IAVI and its collaborators are currently conducting four ongoing trials in India, Kenya, Rwanda, Uganda, South Africa and ...

Scientists genetically engineer tomatoes with enhanced folate content

...s and other developmental problems in children, as well as numerous health issues in adults, such as anemia. "Folate deficiency is a major nutritional deficiency, especially in the developing world," said Parag Chitnis, program director in the National Science Foundation's Division of Molecular and Cel...

Gut research yields new anti-cancer approach

...toxic, destroying microtubules in healthy cells as well as cancer cells," Schaefer said. "Our early studies, however, suggest that general toxicity does not rule out this approach as once feared. With new drug delivery technologies that help drugs target only cancer cells, we are very excited about the po...

Changes in amino acids in the 1918 influenza virus cut transmission

... lead to the emergence of pandemic viruses are not well understood, explains study co-author Adolfo García-Sastre, PhD, Professor of Microbiology at Mount Sinai School of Medicine. "What's most threatening is the possibility of another pandemic, similar to that of 1918, which was caused by a novel influen...

Study finds antibiotic resistance in poultry even when antibiotics were not used

...n the levels were lower, Lee adds, they were still well above the reasonable comfort zone for antibiotic resistance ?roughly five to 10 percent. Seventy-three percent of the bacteria from one flock in the antibiotic-free commercial group were resistant to the drug oxytetracycline, for example, while 90...

Action video games sharpen vision 20 percent

...nts were given a crowding test, which measured how well they could discern the orientation of a "T" within a crowd of other distracting symbols—a sort of electronic eye chart. Students were then divided into two groups. The experimental group played Unreal Tournament, a first-person shoot-'em-up action ga...
