Most people become infected with the human cytomegalovirus (CMV) at some point in life. Over millions of years, our immune system has evolved a trick or two to…
Acidity (pH) and its changes play an important role in many physiological processes, including protein folding, and can act as indicators of cancer. In the…
Specialized proteins unzip the intertwined DNA strands while others follow and build new strands, using the originals as templates. Whenever these proteins…
Since Edison’s first bulb, heat has been a mostly undesirable byproduct of light. Now researchers at Rice University are turning light into heat at the point…
The plague-causing bacteria Yersinia pestis evades detection and establishes a stronghold without setting off the body's early alarms. New discoveries reported…
All a question of timing: When bushcrickets mate, the male attaches a sticky package, the so-called spermatophore, to the female’s abdomen. Alongside the sperm…
Northwestern Medicine researchers have discovered a “two-faced” group of cells at work in human colon cancer, with opposing functions that can suppress or…
The human body contains ten times more bacterial cells than human cells, most of which are found in the gut. These bacteria contain an enormous number of genes…
A chemical nanostructure developed by Boston College researchers behaves much like the pores of the skin, serving as a precise control for a typically stubborn…
“Technological advances have improved our knowledge about the diversity of several nocturnal mammals,” said Rachel Munds from the University of Missouri…
Cold blooded animals, or ectotherms, do not have an internal mechanism for regulating body temperature. Instead, they rely on solar energy captured by the…
Their findings, published today in the journal Emerging Infectious Diseases, could lead to a better understanding of how viruses can cause cancer in animals…
The researchers have used these cancer stem cells to test a new therapeutic approach that one day might be used to treat some of the more aggressive types of…
About one in ten thousand babies is born with an abnormally small head. The cause for this disorder – which is known as microcephaly – is a defect in the…
Until now, it was widely believed that this step takes place in the retinal ganglion cells, the output neurons of the retina. Scientists in the lab of Thomas…
Cell aging, or cellular senescence, has an important role in the natural physiological response to tumor development. Activated oncogenes are able to induce…
