Tesla FSD crashes in fog, sun glare—Feds open new safety investigation
Four crashes and one death could lead to a costly recall or FSD being banned. Today, federal safety investigators opened a new investigation aimed at Tesla's electric vehicles. Th.....»»
Physicists show that neutron stars may be shrouded in clouds of axions
A team of physicists from the universities of Amsterdam, Princeton and Oxford have shown that extremely light particles known as axions may occur in large clouds around neutron stars. These axions could form an explanation for the elusive dark matter.....»»
A method to switch between optical pulling and pushing forces by altering the shape of Fermi arcs in Weyl systems
Optical forces, which act like an invisible "hand," are capable of precisely controlling tiny particles. Optical tweezers, a well-known tool, use this force to capture and manipulate small objects such as cells, bacteria, and viruses. This effect is.....»»
A look into cloudy liquids: New method makes the expansion of turbid drops in water visible
When driving though a bank of fog, car headlights are only of limited help as the light is scattered by the water particles suspended in the air. The situation is similar when you try to observe the inside of a drop of milk in water or the internal s.....»»
EarthCARE synergy reveals power of clouds and aerosols
With the initial images from each of the instruments aboard ESA's EarthCARE satellite now in hand, it's time to reveal how these four advanced sensors work in synergy to measure exactly how clouds and aerosols influence the heating and cooling of our.....»»
Revealing the hidden universe with full-shell X-ray optics
The study of X-ray emission from astronomical objects reveals secrets about the universe at the largest and smallest spatial scales. Celestial X-rays are produced by black holes consuming nearby stars, emitted by the million-degree gas that traces th.....»»
Unique "barcodes" for molecules could help expedite medical advancements
Barcodes are commonly used to track items like groceries or clothing, but University of Central Florida researchers have developed a special "barcode" to identify much smaller objects: molecules......»»
Washington state"s older forests capture carbon better than nearly any other
They tower and drip, their curtains of moss damp in windblown fog: rainforests of the Pacific Northwest, unique in all the world......»»
Comet Tsuchinshan-ATLAS is from the Oort Cloud—the invisible bubble that"s home to countless space objects
The human mind may find it difficult to conceptualize: a cosmic cloud so colossal it surrounds the sun and eight planets as it extends trillions of miles into deep space......»»
Octopus suckers inspire new tech for gripping objects underwater
New adhesive system could be powerful tool for underwater salvage, rescue operations. Over the last few years, Virginia Tech scientists have been looking to the octopus for inspir.....»»
New Kuiper Belt objects lurk farther away than we ever thought
Earth's Kuiper Belt appears to be substantially larger than we thought. In the outer reaches of the Solar System, beyond the ice giant Neptune, lies a ring of comets and dwarf pla.....»»
There were more black holes in the early universe than we thought, research finds
Supermassive black holes are some of the most impressive (and scary) objects in the universe—with masses around 1 billion times more than that of the sun. And we know they've been around for a long time......»»
Solar Sails and Comet Tails: How Sunlight Pushes Stuff Around
It seems crazy, but light actually exerts a physical force on objects. It could power a new generation of spacecraft for deep-space missions......»»
Webb telescope detects unusual gas jets from Centaur 29P
Inspired by the half-human, half-horse creatures that are part of Ancient Greek mythology, the field of astronomy has its own kind of centaurs: distant objects orbiting the sun between Jupiter and Neptune. NASA's James Webb Space Telescope has mapped.....»»
Surprising amount and variety of gamma radiation is produced in large tropical thunderstorms, observations reveal
In the 1990s, NASA satellites built to spot high-energy particles coming from supernovas and other celestial-sized objects discovered a surprise—high energy gamma radiation bursts coming from right here on Earth......»»
Hubble captures stellar nurseries in majestic spiral galaxy IC 1954
This image from the NASA/ESA Hubble Space Telescope features the spiral galaxy IC 1954, located 45 million light-years from Earth in the constellation Horologium. It sports a glowing bar in its core, majestically winding spiral arms, and clouds of da.....»»
Satellite data fusion enhances the early detection of convective clouds
As global warming continues, convective weather events are becoming more frequent. The early stage of these storms, known as convective initiation (CI), can be monitored using geostationary satellites. However, detecting CI accurately remains a chall.....»»
Observations confirm that early-universe quasar neighborhoods are densely populated with companion galaxies
Quasars are the most luminous objects in the universe and are powered by material accreting onto supermassive black holes at the centers of galaxies......»»
