Just as a leaf drifts along with a stream, objects in other moving fluids normally drift along with the flow. That is, unless they exert energy to move against it. Although it may be less intuitive, light waves or photons ...
Engineers at the University of Wisconsin–Madison have designed a new type of quantum nanostructure that could enable optical neural networks. This emerging technology has the potential to make artificial intelligence systems, ...
The Van Allen radiation belts are huge, doughnut-shaped regions of highly energetic charged particles trapped by Earth's magnetosphere. These charged particles play a major role in space weather, so studying them is important ...
When is a billiard ball not a billiard ball? When mathematicians get involved and view a popular game as a model computer.
Exoplanets are exotic worlds orbiting distant stars far beyond our solar system. Ever since the first ones were discovered in the 1990s, astronomers have turned their attention to these distant worlds to understand more about ...
An international team of astronomers from ASTRON, JIVE, the University of Amsterdam and other institutions has found the first so-called "microblazar" in the Milky Way. This stellar system is composed of a massive star and ...
Understanding the origin, acceleration and propagation of high-energy cosmic rays has been a century-old mystery in astrophysics. Recently, joint observations from China's Einstein Probe (EP) satellite and the Large High ...
Ph.D. candidate Natalia Seliutina has followed gemstones from the -30° temperatures of Siberia to the carving studios of Ōtepoti and the particle accelerators of Taiwan in her quest to discover why pounamu is one of the toughest ...
A University of Iowa-led research team has reported in a new study the most detailed observations to date of the bow shock at Jupiter, our solar system's gas giant. The findings from NASA's Juno mission reveal key differences ...
About 100 years ago, archaeologists unearthing pottery sherds in Tampa Bay found something unexpected. Some of the fragments they recovered had designs nearly identical to decorated pottery found hundreds of miles to the ...
