SCIENTISTS ARE CONTINUING to tease out the mechanisms by which the Venus flytrap can tell when it has captured a tasty insect as prey as opposed to an inedible object (or just a false alarm). There is evidence that the carnivorous plant has something akin to a short-term “memory,” and a team of Japanese scientists has found evidence that the mechanism for this memory lies in changes in calcium concentrations in its leaves, according to  a recent paperpublished in the journal Nature Plants.

Smithsonian Scientists Discover Six New Coronaviruses in Bats in Myanmar

Finding new diseases is difficult and dangerous work. In the middle of the night, the researchers would get dressed in protective gear. They would wear suits that covered them from head to toe, goggles, two pairs of gloves, and boots. Then they would go to caves and set up nets to capture bats and tarps to collect their droppings. There would be so many bats that it would take the team just a few minutes to have hundreds to sample. Continue reading Smithsonian Scientists Discover Six New Coronaviruses in Bats in Myanmar

Evidence of Arsenic-Breathing Microbial Life Found in Pacific Ocean

Researchers working off the coast of Mexico have discovered evidence of arsenic-breathing life in oxygen-starved waters. These resilient microbes are a vestige of Earth’s ancient past, but they could also be a sign of things to come under the influence of climate change.
