Saturday Citations: Ancient corvids, tetraquarks, and researchers who aren't bored hearing about your dreams

This week, researchers reported on two-dimensional gold sheets, a tidy little meson made of four quarks (and its buddy!) and a big and almost unimaginably dense exoplanet with an exciting backstory.

Muon g-2 doubles down with latest measurement, explores uncharted territory in search of new physics

Physicists now have a brand-new measurement of a property of the muon called the anomalous magnetic moment that improves the precision of their previous result by a factor of 2.

Printing atom by atom: Lab explores nanoscale 3D printing

It takes chemist Liaisan Khasanova less than a minute to turn an ordinary silica glass tube into a printing nozzle for a very special 3D printer. The chemist inserts the capillary tube—which is just one millimeter thick—into ...

'Forever chemicals' destroyed by simple new method

PFAS, a group of manufactured chemicals commonly used since the 1940s, are called "forever chemicals" for a reason. Bacteria can't eat them; fire can't incinerate them; and water can't dilute them. And, if these toxic chemicals ...

Using graphene foam to filter toxins from drinking water

Some kinds of water pollution, such as algal blooms and plastics that foul rivers, lakes, and marine environments, lie in plain sight. But other contaminants are not so readily apparent, which makes their impact potentially ...

Wormholes may be lurking in the universe—and new studies are proposing ways of finding them

Albert Einstein's theory of general relativity profoundly changed our thinking about fundamental concepts in physics, such as space and time. But it also left us with some deep mysteries. One was black holes, which were only ...

Mathematicians create a method for studying the properties of porous materials

Mathematicians from RUDN University have studied the properties of compositional operators in spaces with mixed Lebesgue norms. Their work will help describe the diffusion of liquids in materials with cracks and in porous ...

Physicist suggests 'quantum foam' may explain away huge cosmic energy

Steven Carlip, a physicist at the University of California, has come up with a theory to explain why empty space seems to be filled with a huge amount of energy—it may be hidden by effects that are canceling it out at the ...
