Ultrashort pulses play a significant role in spectroscopic applications. Their broad spectral bandwidth enables simultaneous characterization of the sample at various frequencies, eliminating the need for repeated measurements ...
New movies of two of the most famous objects in the sky—the Crab Nebula and Cassiopeia A—are being released from NASA's Chandra X-ray Observatory. Each includes X-ray data collected by Chandra over about two decades. ...
A computer game helped upper secondary school students become better at distinguishing between reliable and misleading news. This is shown by a study conducted by researchers at Uppsala University and elsewhere.
Magnetic cilia—artificial hairs whose movement is powered by embedded magnetic particles—have been around for a while, and are of interest for applications in soft robotics, transporting objects and mixing liquids. However, ...
A new imaging technique developed by engineers at Washington University in St. Louis can give scientists a much closer look at fibril assemblies—stacks of peptides that include amyloid beta, most notably associated with ...
A study of policing at WorldPride and Mardi Gras events in 2023 found it was heavy-handed and damaging to its relationship with the LGBTQIA+ community.
A new way of quickly distinguishing between illegal elephant ivory and legal mammoth tusk ivory could prove critical to fighting the illegal ivory trade. A laser-based approach developed by scientists at the Universities ...
Scientists have developed a sustainable new way of making complex molecules, which could greatly reduce waste produced during drug manufacturing, a study suggests.
Entanglement is a form of correlation between quantum objects, such as particles at the atomic scale. The laws of classical physics cannot explain this uniquely quantum phenomenon, yet it is one of the properties that explain ...
Electrons inside solid materials can only take certain values of energy. The allowed energy ranges are called "bands," and the space between them, the forbidden energies, is known as "band gaps." Both of them together constitute ...
