The Paleocene–Eocene Thermal Maximum (PETM) is a period of global warming that occurred ~56 million years ago, lasting approximately 200,000 years, when the Earth experienced global surface temperature elevations of ~5°C.
The ability to hide an arbitrary object with a cloak at a distance from the object is a unique task in photonics research, although the phenomenon is yet to be realized in practice. In a recent study now published in Light: ...
To enable negative refraction and related optical illusions, metamaterials are artificially engineered with unique properties that result from their internal physical structures, rather than their chemical composition. The ...
The phenomenon of ionic wind has been known about for centuries: by applying a voltage to a pair of electrodes, electrons are stripped off nearby air molecules, and the ionized air collides with neutral air molecules as it ...
(Phys.org)—The piezoelectric effect, which causes a material to expand along the direction of an applied electric field, is common in many materials and used in a variety of technologies, from medical ultrasound to vibration-powered ...
Astronomers have long sought to understand the early universe, and thanks to the James Webb Space Telescope (JWST), a critical piece of the puzzle has emerged. The telescope's infrared detecting "eyes" have spotted an array ...

This first week of September, researchers reported on burned-out sharks, a method for maintaining quantum coherence and some positive market news for old-timey coal barons. Plus: Snail slime is really impressive if you look ...
Research led by Arizona State University, Tempe, has looked into how urbanization, species traits and environmental factors interact to shape urban wildlife communities. This research is essential for effective conservation ...
For all of the unparalleled, parallel-processing, still-indistinguishable-from-magic wizardry packed into the three pounds of an adult human brain, it obeys the same rule as the other living tissue it controls: Oxygen is ...
