boils down to energy expenditure. The offspring of leptin-treated mothers burn up more energy. 'The infants are permanently inefficient in terms of using energy,' says Cawthorne. Leptin-based products may also find their way into the pet obesity m...

in the initial viral entry in the central nervous system. We actually saw that the virus replicated better with the binding site than without it. LC8 is a transcription factor that helps the virus efficiently replicate in cells." The researchers we...
UF scientists discover new genus of frogmouth bird in Solomon Islands
...frogs.For perspective on the scale of evolutionary difference
between genera, consider that modern humans and Neanderthals are different species within the same genus (Homo), while chimpanzees are our living relatives from a closely related genus (Pan), but that we share the same taxonomic family (Hominidae) wi...

in surface fuels between logged and unlogged units would persist for about 15 years. The simulation also showed that if a fire did start during this time, it would likely kill most young trees as the fire carried through either logged or unlogged st...
