Closely related species consume the same resources less often than more remotely related species. In fact, it is the competition for resources, and not their kinship, which determines the food sources of the species of a community. Under the effect of this competition, closely related species have specialized on different food resources.
When green algae "can't breathe," they get rid of excess energy through the production of hydrogen. Biologists have found out how the cells notice the absence of oxygen. For this, they need the messenger molecule nitric oxide and the protein haemoglobin, which is commonly known from red blood cells of humans.
Therapeutic hypothermia is rarely being used in patients who suffer cardiac arrest while in the hospital, despite its proven potential to improve survival and neurological function, researchers report.
Hospitals are synonymous with cleanliness and now an academic medical center is taking disinfection to futuristic levels. Nicknamed “little Joe” a 3-foot upright cylindrical r...
Scientists have built a nanoscale transistor that works at room temperature. The device, only 20 nanometers wide, is made of gold quantum dots mounted on boron nitride nanotubes.
Materials scientists have found an accurate way to explain the magnetic properties of a lanthanum-cobalt-oxygen compound that has mystified the scientific community for decades.
Researchers have revealed that a protein well known for its role in Alzheimer's disease controls spindle development in muscle and leads to impaired movement in mice when the protein is absent or treated with inhibitors.
Development of skin cancer may require changes in the genes that control cell shape, report a team of scientists. The work could lead to a better understanding of how the cells become metastatic.
The daring and adventurous sloth bear cub, Hank, made his public debut at the Smithsonian’s National Zoo this week. He is the first sloth bear born at the Zoo in seven years.
A new study provides an important new insight into how cancer cells are able to avoid the cell death process. The findings may suggest a chemotherapeutic approach to prevent the spread of cancers.
