Study shows animals like crickets use the ground to amplify calls

When animals "sing" sitting on the ground—such as when crickets chirp—their volume and reach increase dramatically, by as much as ten-fold. This result from a study by Western researchers, published today in the journal PNAS, contradicts long-held beliefs in the field of animal communication, which presume the ground is a hindrance to sound transmission.

Why a surprising discovery, warming seas and the demise of the 'Meg' may spell trouble for more and more sharks

Some unexpected shark strandings and subsequent surprises following autopsies have ironically taken marine biologists millions of years back in time as they look to the future with concern. Adding chapters to an evolutionary tale involving the infamous megalodon shark (the "Meg"), they think their work suggests there are more warm-blooded sharks out there than previously believed, and—based on the Meg's demise—these species may be at great risk from warming seas.

Study shows willow bark extract has broad-spectrum antiviral effect

From a seasonal cold to a stomach bug, nobody likes catching a virus—and epidemics can be devastating. We need safe, sustainable antiviral options to treat the outbreaks of the future. Scientists in Finland have now shown that an extract of willow bark—a plant that has already provided several medicines, including the precursor to modern aspirin—has a broad-spectrum antiviral effect in cell sample experiments.
