New research finds three alternative answers beyond errors in handler or dog training that can explain why dogs trained to identify scat for conservation purposes sometimes collect non-target scats.
Human herpesviruses such as HHV-6 can remain dormant in cells for many years without being noticed. When reactivated, they can cause serious clinical conditions. Researchers have now found a way of differentiating between active and inactive viruses.
Using the fossil record to accurately estimate the timing and pace of past mass extinctions is no easy task, and a new study highlights how fossil evidence can produce a misleading picture if not interpreted with care.
By analogy to linear polymers, which reptate with a random walk embedded in a 3D network, we show that star polymers relax by a random walk in a 5D network.
As mammals age, immune cells in the brain known as microglia become chronically inflamed. In this state, they produce chemicals known to impair cognitive and motor function. That’s one explanation for why memory fades and other brain functions decline during old age. But, according to a new study, there may be a remedy to delay the inevitable: dietary fiber.
