Hubble shows winds in Jupiter’s great red spot are speeding up

Like the speed of an advancing race car driver, the winds in the outermost “lane” of Jupiter’s Great Red Spot are accelerating – a discovery only made possible by NASA’s…

Zen stones naturally placed atop pedestals of ice

… a phenomenon finally understood. Like a work of art enshrined in a museum, some stones end up on a pedestal of ice in nature, with no human intervention. This…

Hungry or full: It comes down to the atomic details

Insight into the molecular structure of an appetite-regulating cell receptor A protein – measuring just a few nanometers in size – acts as a molecular switch with a crucial role…

Artificial opals measure temperature and time

Researchers in Bayreuth discover novel sensors. Due to their iridescent colors, opals have been considered particularly precious gemstones since antiquity. The way these stones shimmer is caused by their nanostructures….

Ultrathin electronic barrier layer to control interface luminescence

In a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2021.200064, Researchers led by Professor Xu Chunxiang, Southeast University, Nanjing, China discuss nano-buffer controlled electron tunneling to regulate heterojunctional interface emission. Light emitting…

Gamma rays and neutrinos from mellow supermassive black holes

The Universe is filled with energetic particles, such as X rays, gamma rays, and neutrinos. However, most of the high-energy cosmic particles’ origins remain unexplained. Now, an international research team…

Hubble captures a cluster in the heart of the Milky Way

This sparkling starfield, captured by the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 and Advanced Camera for Surveys, contains the globular cluster ESO 520-21 (also known as Palomar 6)….

A 3D printed vaccine patch offers vaccination without a shot

Stanford University and the University of North Carolina Chapel Hill develop microneedle vaccine patch that outperforms needle jab to boost immunity. Scientists at Stanford University and the University of North…
