Astronomers unmask cosmic eruptions in nearby galaxies

A brief burst of high-energy light swept through the solar system on April 15, triggering many space-based instruments, including those aboard NASA and European missions. Now, multiple international science teams conclude ...

Reducing traps increases performance of organic photodetectors

Physicists at the Dresden Integrated Center for Applied Physics and Photonic Materials (IAPP) discovered that trap states rule the performance of organic photodetectors, ultimately limiting their detectivity. These highly ...

Chimpanzee friends fight together to battle rivals

Chimpanzees, one of the closest relatives of humans, cooperate on a group level—in combative disputes, they even cooperate with group members to whom they are not related. Those involved in fights with neighboring groups ...

Fungi strengthen plants to fend off aphids

Researchers at the University of Copenhagen have demonstrated that unique fungi strengthen the immune systems of wheat and bean plants against aphids. Fungi enter and influence the amount of a plant's own defenses, resulting ...

Geoscientists reconstruct 6.5 million years of sea level stands

The pressing concern posed by rising sea levels has created a critical need for scientists to precisely predict how quickly the oceans will rise in coming centuries. To gain insight into future ice sheet stability and sea-level ...
