Scientists have been able to shed light on important neural circuitry involved in the prey capture behavior exhibited by young zebrafish. The findings show that neurons in the retina of the eye already filter out prey objects from other environmental signals.
Mistletoe hanging in doorways announces that the holidays are just around the corner. For some...
Biochemists from NYU Langone Medical Center found that epigenetic changes in mice and...
As the main component of connective tissue in the body, fibroblasts are the most common type of...
Most vaccines work by inducing an immune response characterized by neutralizing antibodies against the respective pathogen. A new study reports that a combination of antibodies from llamas can neutralize a wide range of circulating HIV viruses.
Until now, no computer model has been able to match the primate brain at visual object recognition during a brief glance. However, a new study has found that one of the latest generation of these so-called “deep neural networks” matches the primate brain. This improved understanding of how the primate brain works could lead to better artificial intelligence and, someday, new ways to repair visual dysfunction.
Ibuprofen, a common over-the-counter drug used to relieve pain and fever, could hold the keys to a longer healthier life. The study showed that regular doses of ibuprofen extended the lifespan of yeast, worms and fruit flies an average of 15%.
The most advanced system to date for studying fruit flies in space, NASA’s Fruit Fly Lab, is making its debut aboard the International Space Station. The Fruit Fly Lab-01 mission, planned to launch to the station in December aboard SpaceX's fifth commercial resupply services (CRS) mission, is the first of a series of fruit fly investigations NASA plans to conduct.
Like human patients, mice with a form of Duchenne muscular dystrophy undergo progressive muscle degeneration and accumulate connective tissue as they age. Now, researchers at the Stanford University School of Medicine have found that the fault may lie at least partly in the stem cells that surround the muscle fibers.
Through research in mice, Johns Hopkins and University of Alberta researchers have identified a single protein as the root of painful and dangerous allergic reactions to a range of medications and other substances. If a new drug can be found that targets the problematic protein, it could help smooth treatment for patients with conditions ranging from prostate cancer to diabetes to HIV.
Whether an odor is pleasant or disgusting to an organism is not just a matter of taste. Often, an organism’s survival depends on its ability to make just such a discrimination. However, odor sources can also be signs of lethal hazards. Scientists have now found that in fruit flies, the quality and intensity of odors can be mapped in the so-called lateral horn.
Extra vitamin E protected older mice from a bacterial infection that commonly causes pneumonia. Microbiologists and nutrition researchers report that the extra vitamin E helped regulate the mice’s immune system. The findings show promise for studies investigating the effects of vitamin E and infection in humans.
Pentair Aquatic Eco-Systems, Inc. has acquired PR Aqua Supplies Ltd., a leading aquaculture design and equipment provider based in Nanaimo, BC, Canada.
Scientists have long known the p53 protein suppresses tumors. However, a recent animal study has uncovered a complicated relationship between p53 and another protein, Rbm38, highlighting how the body calibrates protein levels.
An exceptionally sensitive toxicity test could make it possible to uncover more dangerous side effects early in pharmaceutical development so that fewer patients are given unsafe drugs.
Researchers have developed the first large animal model of an inherited arrhythmic syndrome — an advance that will lead to a better understanding of the biologic mechanisms important in normal heart conduction and rhythm.
Scientists have demonstrated a technique for “editing” the genome in sperm-producing adult stem cells, a result with powerful potential for basic research and for gene therapy.
The variety-induced overeating typical of holidays is known as the “smörgåsbord effect,” and was first identified in 1956 by the French physiologist Jacques Le Magnen. To study the effects of food flavors on appetite, Le Magnen made tiny feasts for rats.
Researchers have used a microscopic worm (C. elegans) to identify a new path that could lead to drugs to slow aging and the chronic diseases that often accompany it — and might even lead to better cosmetics.
