Salk researchers make fast strides towards understanding how our body controls walking

...in spinals cords lacking functional V1 neurons had slowed to a crawl. "From what we knew about these cells, we were a bit puzzled at first because we had expected to see a loss of coordination," said Goulding. "But after delving into the circuitry further, it made perfect sense. Once excited, motor neurons ...

New research shows bats have complex skills to deal with 'clutter'

...nes in the "Batlab," Moss's team was able to match slowed video and audio recordings of the bat's echolocation activity and corresponding movement as it pursued an insect tethered to a string. The insect could be out in the open, or nestled in among leaves. "We have found that bats adjust the timing of the...

Calcium and vitamin D supplements offer modest bone improvements, no benefits for colorectal cancer

...nts outweighs the risks." "The study's findings of slowed bone loss and the reduction in hip fractures for some groups suggest a role for these supplements in preventing hip fracture in generally healthy postmenopausal women and support the current Surgeon General's recommendations for these nutrients," add...

Study finds drug may cut down involuntary movements

...mmon side effect was sleepiness, but restlessness, slowed movement and depression were also seen in some subjects. Suicide is common in Huntington's disease, and one subject committed suicide during the study. Patients will also need close supervision so that suicide can be prevented."...

Study suggests 'noise' in gene expression could aid bacterial pathogenicity

... of the synthetic gene increased sharply as growth slowed and then stopped. "We were initially skeptical of our own results because they were so counterintuitive," said Collins. "But our laboratory experiments confirmed this increase in gene-expression variability, or noise, when growth stops. We think ther...

Declining snowpack cools off CO2 emissions from winter soils, says U. of Colorado study

A recent decrease in Rocky Mountain snowpack has slowed the release of heat-trapping carbon dioxide gases from forest soils into the atmosphere during the dead of winter, according to a new University of Colorado at Boulder study. Professor Russell Monson of CU-Boulder's ecology and evolutionary biology ...

Evolution study tightens human-chimp connection

...han the molecular clock of the chimp, while it has slowed down 11 percent from the gorilla's molecular clock. This slow down in the molecular clock correlates with a longer generation time because substitutions need to be passed to the next generation in order to have any lasting effect on the species, "A l...

...sease onset improved clinical symptoms of disease, slowed disease progression, reduced disease relapses, and reduced the number of antigen-specific T cells. The authors delved further to unravel the cellular signaling events underlying these beneficial effects. Taken together, the data provide a basis for t...

Study fishes out new role for prostaglandins

...d with the inhibitor, gastrulation was arrested or slowed down significantly. The resulting embryo was also shorter than an untreated embryo. "What is spectacular," said Solnica-Krezel, "is thatif you just put some prostaglandin back in the culture medium, you rescue the phenotype." In another set of embr...

Gene therapy for muscular dystrophy fixes frail muscle cells in animal model, Stanford study finds

...as a lot of potential to overcome issues that have slowed the field of gene therapy," Calos said. Calos said her approach has two advantages: one is that in her method the gene gets inserted directly into the cell's own DNA, which is why the correction is permanent. In some other methods the gene stays outs...

Some good news for the world's poor

...China andIndia, the increase in experimental yield slowed down in the 1990s. "One of the reasons is a lack of agricultural research investment at both the national and international levels," he warns. "The budget of the International Rice Research Institute has also been severely cut in recent years. IRRI's...

Univ. of Chicago scientists find potential cause of breathing problems in Rett Syndrome children

... with RS. Along with breathing problems, RS causes slowed brain and head growth, mental retardation, seizures, gait abnormalities and handwringing. "It is absolutely tragic for the family," said Jan-Marino Ramirez, professor of organismal biology and anatomy at Chicago and lead author of the paper. "It's a ...

NJIT study shows nanoparticles could damage plant life

...ows that nanoparticles of alumina (aluminum oxide) slowed the growth of roots in five species of plants -- corn, cucumber, cabbage, carrot and soybean. Alumina nanoparticles are commonly used in scratch-resistant transparent coatings, sunscreen lotions that provide transparent-UV protection and environmenta...

Researchers uncover new genes that control longevity

... studies also suggest a new model for how aging is slowed when caloric intake is restricted. Molecular biologists Matt Kaeberlein, Brian Kennedy, Stanley Fields, and colleagues at the University of Washington, reported in the November 18, 2005, issue of the journal Science that by decreasing the function of...

Marathon of nano-sprinters

...s consequence is that the movement of the cargo is slowed down. In addition, the force felt by each pulling motor strongly increases the unbinding probability for such a motor. Furthermore, as more motors unbind, each of the remaining pulling motors has to sustain a larger force, which would mean that their...

Stanford scientists' discovery of hormone offers hope for obesity drug

...those given no obestatin. Obestatin treatment also slowed the movement of digested food from the stomach into the intestines. All that remained for the researchers to do was to match this newly discovered hormone to the right receptor. Once again, evolutionary conservation made their work a little easier. I...

From one cell, many possible cures

...Up until now, however, stem cell research has been slowed by ethical controversy -- as well as by the rarity of the extraordinary cells themselves. That could be about to change: A Florida State University research team in Tallahassee, Fla. reports that it has designed a biomedical device that will allow st...

Researchers develop new method to help find deadly malaria parasite's Achilles heel

"Our findings may lead to genetic strategies that suppress undesirable cell division after transplantation, not only for ESCs and their derivatives, but perhaps for adult stem cells as well." Li adds that much more work is ne...
