Very small biological samples and even individual biomolecules can now be examined under near-physiological conditions with high confidence at the BESSY II infrared beamline using a newly validated and improved technique: ...

It's no secret that plastic and other human trash are a problem for marine life, but our understanding has long focused on the ocean's surface. As described in a study published in PLOS One, a more complete picture is coming ...

Intricate designs engraved across the surface of 18,000-year-old female figurines carved from mammoth ivory were inspired by the distinctive growth patterns visible in the tusks, a new study published in the journal npj Heritage ...

Washington State University researchers have discovered how a group of coronaviruses circulating in hedgehogs invades host cells, a key to understanding their potential to jump between species and their risk of causing a ...

Laser scanning, often referred to as lidar, has rapidly transformed how tropical forest regions are studied, monitored and understood across academic disciplines. The technology enables researchers to peer through dense forest ...

Research initiated as part of a bachelor's thesis in physics at the Universitat Autònoma de Barcelona (UAB) has culminated in a new analytical description of the muon-based calibration of dual-mirror Cherenkov telescopes. ...

A research team at the Max Planck Institute for Chemical Ecology discovered a previously unknown strategy by which certain fungi neutralize spruce defense compounds. These fungi are introduced into trees by bark beetles, ...

Astronomers have confirmed that one of the fastest-changing stars ever observed has entered a new stage of its evolution, offering a rare opportunity to watch a star's life unfold on human timescales.

Across its basins and thousands of meters down, the Mediterranean Sea is getting warmer and saltier. Now, a new study finds it is also doing so at an increasingly rapid pace. The speedup is largest in the central and eastern ...

Researchers at the University of Eastern Finland have uncovered two complementary mechanisms that govern coherence in miniaturized lasers composed of metallic nanoparticle arrays incorporated into an optical gain material, ...

From social media to the streets of Washington, D.C., the organized white nationalist movement has become more visible in the United States over the past few decades. But the extent of this extremist movement's appeal to ...

Crystals are usually imagined as rigid objects with flat faces and straight edges. A research team led by the University of Osaka has recently created a porous crystal that grows into a spring-like helix. The team also found ...
