Remdesivir prevents MERS coronavirus disease in monkeys

The experimental antiviral remdesivir successfully prevented disease in rhesus macaques infected with Middle East respiratory syndrome coronavirus (MERS-CoV), according to a new study. Remdesivir prevented disease when administered before infection and improved the condition of macaques when given after the animals already were infected.

Forests bouncing back from beetles, but elk and deer slowing recovery

New research reveals that even simultaneous bark beetle outbreaks are not a death sentence to the state's beloved forests. The study found that high-elevation forests in the southern Rocky Mountains actually have a good chance of recovery, even after overlapping outbreaks with different kinds of beetles. One thing that is slowing their recovery down: Foraging elk and deer.

Skyrmions like it hot: Spin structures are controllable even at high temperatures

Researchers who had previously demonstrated the use of new spin structures for future magnetic storage devices has yet achieved another milestone. The international team is working on structures that could serve as magnetic shift registers, so called racetrack memory devices. This type of storage promises low access times, high information density, and low energy consumption.

Scientists finally figure out how millipedes actually do it

Scientists have a pretty good handle on how the birds and the bees work, but it comes to mating, almost all millipedes have been a mystery -- until now. For the first time, researchers have puzzled out how these tiny creatures' complex genitalia work, thanks to new imaging techniques and blacklights that make the different tissues glow.

How a tiny and strange marine animal produces unlimited eggs and sperm over its lifetime

A little-known ocean-dwelling creature most commonly found growing on dead hermit crab shells may sound like an unlikely study subject for researchers, but this animal has a rare ability—it can make eggs and sperm for the duration of its lifetime. This animal, called Hydractinia, does so because it produces germ cells, which are precursors to eggs and sperm, nonstop throughout its life. Studying...

As groundwater depletes, arid American West is moving east

Even under modest climate warming scenarios, the continental United States faces a significant loss of groundwater—about 119 million cubic meters, or roughly enough to fill Lake Powell four times or one quarter of Lake Erie, a first-of-its-kind study has shown.
