A new study shows that the frequency of polar vortex disruptions that is most favorable for extreme winter weather in the United States is increasing, and that Arctic change is likely contributing to the increasing trend. ...

In recent years, physicists and electronics engineers have been trying to devise strategies to control or produce quantum states of matter in different materials. Such strategies could ultimately prove valuable for the development ...
Many people are living on pandemic time. Before COVID and after COVID, in other words. And the post-pandemic world is rapidly changing as more people get vaccinated. Students are going back to school, parents are going back ...

In solar cells, about two third of the energy of sunlight is lost. Half of this loss is due to a process called 'hot carrier cooling' where high energy photons lose their excess energy in the form of heat before being converted ...

Electrolysis, passing a current through water to break it into gaseous hydrogen and oxygen, could be a handy way to store excess energy from wind or solar power. The hydrogen can be stored and used as fuel later, when the ...

For plants, sunlight can be a double-edged sword. They need it to drive photosynthesis, the process that allows them to store solar energy as sugar molecules, but too much sun can dehydrate and damage their leaves.

Semiconductors convert energy from photons (light) into an electron current. However, some photons carry too much energy for the material to absorb. These photons produce "hot electrons," and the excess energy of these electrons ...
