Conventional treatment with epoetin (a synthetic form of human erythropoietin that promotes red-blood cell production) to manage anaemia in chronic kidney…
While it has been thought that cytokines (secreted signalling molecules) such as interleukin-4 or interleukin-13 have a critical role in onset and development…
One corollary of this assumption is that achromatic colors, or perceived grey shades, are contained in a one-dimensional (1-D) space varying from bright to…
The world’s major rice-producing nations – including China and India – are calling for closer collaboration in efforts to feed Asia’s billions of rice…
Scientists led by Leslie Vosshall, head of the Laboratory of Neurogenetics and Behavior, have found that this protein, called SNMP, or Sensory Neuron Membrane…
Investigators from six countries have completed the second phase of the International HapMap Project, an effort to identify and catalog genetic similarities…
That final step – called spermiogenesis – entails the compaction of DNA into a tight ball within the head of the sperm so it can successfully penetrate an egg.Mice engineered to lack the crucial gene, Jhdm2a, that triggers this process did not produce many mature sperm, and those they did produce had abnormally shaped heads and immotile tails….
Cheaters lose. Tuberculosis settles into the lungs. Helicobacter pylori, the microbe causing ulcers, burrows into the stomach where it thrives on acids. And…
The acidity is caused by the gradual buildup of carbon dioxide (CO2) in the atmosphere, dissolving into the oceans. Scientists fear it could be lethal for…
Vanderbilt University Medical Center researchers, working with colleagues in Texas, have found that insulin levels affect the brain’s dopamine systems, which…
That's according to research done by Lisa A. Schulte, assistant professor in Iowa State University's department of Natural Resource Ecology and Management and…
While developing new lenses for next-generation sensors, researchers have crafted a layered material that causes light to refract, or bend, in a manner nature…
Researchers have discovered a strain of bacteria resistant to all approved drugs used to fight ear infections in children, according to an article to be…
While they have proven useful for these purposes, no one really knows much about what’s going on at the molecular level. For example, how do nanotubes and…
The findings are published in this week’s issue of the scientific journal PLoS ONE. The scientists studied the aquatic animal Hydra, a member of Cnidaria,…
Schizophrenia may occur, in part, because of a problem in an intermittent on/off switch for a gene involved in making a key chemical messenger in the brain,…
