A University of Massachusetts Amherst-led research team has discovered that weaker rock in mountain landscapes erodes three times faster than harder rock—even on gentler slopes—and is one of the main attributes governing ...

Inside the cell nucleus, DNA is wrapped around histone proteins to form nucleosomes, which are further organized into chromatin. Chromatin has traditionally been divided into transcriptionally active euchromatin and relatively ...

A collaborative research team led by Yasuhiro Kobori at Kobe University, together with researchers from Toho University, Saitama University, Nagoya Institute of Technology and the University of Freiburg, has identified a ...

Science can't study a species—or unlock its potential to change the world—until people actually know it exists. Four new species of frogs have now been given names, thanks to the efforts of FIU biologist Alessandro Catenazzi.

Particle accelerators are expensive. Not just to build or to run, but also to predict the outcome of measurements obtained from them.

In 2016, a binary star system emitting unusually strong gamma rays was discovered in our galactic neighborhood. Now, astronomers have found the smoking gun, or rather, a smoking trail of cool molecular gas that suggests jets ...

A nanoscale particle with a unique structure, developed at MIT, holds potential as a customizable delivery vehicle for personalized cancer vaccines. The backbone of the vaccine is a modified, harmless bacteriophage called ...

A new modeling study, published in the journal Nature Climate Change, suggests that the East Antarctic Ice Sheet may be more resilient to extreme long-term warming than previously estimated. Increased snowfall, greater cloud ...

Our cells are a hotbed of activity, with reactions churning away to keep us alive. But the cytoplasm, where many metabolic reactions take place, is not uniform. Instead, proteins and other molecules cluster together into ...

Finding new drugs requires screening vast numbers of compounds to identify those that interact with a biological target. DNA-encoded libraries (DELs) help researchers explore these large collections by attaching a short DNA ...

Researchers have created a molecular "cage" that keeps protein-degrading drug molecules inactive until they are exposed to low-energy red light. The technology, called RuPHOTACs, controls when and where these molecules become ...

Nitrogen dioxide is a harmful gas that requires sensitive detection. Researchers used intense light pulses lasting 10 milliseconds to make molybdenum disulfide flakes and anchor isolated metal atoms in one step. Adding platinum ...
