...rmes, in which the orphan boy Làzaro helps a blind man see. Of the molecules known to control TRP channels, a key player is diacylglycerol, known as DAG. DAG is known to be made by a well-studied biochemical pathway. The researchers found that Lazaro provides a second way to make DAG, enabling the cell ...

...al paternity. "The issue of paternity--whether a man really is the biological father of his supposed children--has long been a topic of interest to anthropologists, as well as a staple subject of idle gossip," writes Kermyt G.

Scientists reveal how deadly toxin hijacks cells

...warfare and one of the most lethal toxins known to man - is able to sneak into cells. The finding is crucial for the development of new treatments against botulism, a paralytic illness caused by the toxin more commonly known as botox. As small amounts of botox are also known to alleviate many medical p...

Avian influenza virus in mammals spreads beyond the site of infection to other organ systems

...on). While spread of avian influenza from bird to man is known to occur, as first reported during the 1997 Hong Kong outbreak, human-to-human spread is extremely rare. Thus, the disease events that take place during mammal-to-mammal spread are not well characterized. To assess the spread of H5N1 inf...
