New sunspots potentially herald increased solar activity

On May 29, 2020, a family of sunspots -- dark spots that freckle the face of the Sun, representing areas of complex magnetic fields -- sported the biggest solar flare since October 2017. Although the sunspots are not yet visible (they will soon rotate into view over the left limb of the Sun), NASA spacecraft spotted the flares high above them.

How the coronavirus could be prevented from invading a host cell

How might the novel coronavirus be prevented from entering a host cell in an effort to thwart infection? A team of biomedical scientists has made a discovery that points to a solution. The scientists report that two proteases -- enzymes that break down proteins -- located on the surface of host cells and responsible for processing viral entry could be inhibited.

Paper-thin gallium oxide transistor handles more than 8,000 volts

Electrical engineers created a gallium oxide-based transistor that can handle more than 8,000 volts. The transistor could lead to smaller and more efficient electronic systems that control and convert electric power -- a field of study known as power electronics -- in electric cars, locomotives and airplanes. In turn, this could help improve how far these vehicles can travel.

Integrating satellite and socioeconomic data to improve climate change policy

Bangladesh is on track to lose all of its forestland in the next 35-40 years, leading to a rise in CO2 emissions and subsequent climate change, researchers said. However, that is just one of the significant land-use changes that the country is experiencing. A new study uses satellite and census data to quantify and unravel how physical and economic factors drive land-use changes. Understanding...

Yes, your dog wants to rescue you

Imagine you're a dog. Your owner is trapped in a box and is crying out for help. Are you aware of his despair? If so, can you set him free? And what's more, do you really want to? That's what researchers wanted to know when they gave dogs the chance to rescue their owners.

New view on how tissues flow in the embryo

Watching and measuring what happens in tissues inside the human embryo is currently not possible, and it's difficult to do in mammalian models. Because humans and the fruit fly Drosophila share so many biological similarities, researchers tackled this problem by focusing on fruit flies. The team reports today that they can predict when the tissue will begin to rapidly flow just by looking at cell...

When COVID-19 meets flu season

As if the COVID-19 pandemic isn't scary enough, the flu season is not far away. How severe will the flu season be as it converges with the COVID-19 outbreak? What can we do to prepare?

Study charts developmental map of inner ear sound sensor in mice

A team of researchers has generated a developmental map of a key sound-sensing structure in the mouse inner ear. Scientists analyzed data from 30,000 cells from mouse cochlea, the snail-shaped structure of the inner ear. The results provide insights into the genetic programs that drive the formation of cells important for detecting sounds and the underlying causes for some forms of inner ear...
