Why Do So Many Tiny Asteroids Have Moons?
Scientists are putting a new spin on the creation of binary asteroids.....»»
Contact binary asteroids are common, but we"ve never seen one form. Now, researchers want to make one
Ever want to play a game of cosmic billiards? That's commonly how the DART mission was described when it successfully changed the orbit of a near-Earth asteroid last year. If you want an idea of how it works, just Google it and an Easter egg from the.....»»
A tiny quadcopter could gather rocks for China"s sample return mission
Space exploration is always changing. Before February 2021 there had never been a human made craft flying around in the atmosphere of another world (other than rocket propelled landers arriving or departing). The Mars Perseverance rover changed that,.....»»
Giant sea salt aerosols found to play major role in Hawai"i"s coastal clouds, rain
Despite their tiny sizes, aerosols, such as sea salt, dust, and ash, play a giant role in shaping weather and climate. These particles scatter light, act as the starting point for cloud formation, and can even initiate or limit rainfall. A new study.....»»
This tiny spinal stimulator could someday have a big impact on paralysis
A Johns Hopkins materials scientist and a team of collaborators have developed a tiny device that may hold promise for restoring mobility to those with lower limb paralysis, a condition affecting approximately 1.4 million Americans......»»
Tiny beads preserve enzymes for biocatalysis
Plasmas can provide the co-substrate needed for biocatalysis of valuable substances, but they are also harmful to enzymes. By attaching enzymes to small beads, the enzymes are protected and remain active up to 44 times longer......»»
New computer code for mechanics of tissues and cells in three dimensions
Biological materials are made of individual components, including tiny motors that convert fuel into motion. This creates patterns of movement, and the material shapes itself with coherent flows by constant consumption of energy. Such continuously dr.....»»
Using tiny traps to study protein interactions can provide new knowledge about difficult-to-treat diseases
Proteins that form clumps occur in many difficult-to-treat diseases, such as ALS, Alzheimer's, and Parkinson's. The mechanisms behind how the proteins interact with each other are difficult to study, but now researchers at Chalmers University of Tech.....»»
A novel system for slip prevention in unmanned rovers
Given the hostile conditions of extraterrestrial environments, unmanned rovers play a critical role in the exploration of planets and moons. NASA's Mars and lunar exploration rovers have significantly contributed to our understanding of these extrate.....»»
How tiny hinges bend the infection-spreading spikes of a coronavirus
A coronavirus uses protein "spikes" to grab and infect cells. Despite their name, those spikes aren't stiff and pointy. They're shaped like chicken drumsticks with the meaty part facing out, and the meaty part can tilt every which way on its slender.....»»
Caribbean island of Dominica creates world"s first marine protected area for endangered sperm whale
The tiny Caribbean island of Dominica is creating the world's first marine protected area for one of earth's largest animals: the endangered sperm whale......»»
Tiny Big Bang: ALICE experiment restarts with lead ions
On September 26, 2023, the accelerator team at the CERN European Council for Nuclear Research in Geneva declared stable lead-beam conditions, ushering in the first data-taking campaign of lead-ion collisions in five years. From then until the late ev.....»»
Gigabyte BIOS update outs next-gen AMD Ryzen APUs with upgraded Radeon GPUs
Desktop APUs with good iGPUs are useful for tiny PCs and low-budget builds. Enlarge (credit: AMD) The Ryzen 7000 desktop CPU series was AMD’s first to include a small integrated GPU by default to make the chips more ap.....»»
ESA is testing a modular multipurpose rover that could be a science lab or a tiny bulldozer
Most rovers have been built for Mars, and each one of them is a complex machine designed with specific goals and terrains in mind. But the moon is different than Mars. We're not searching for life there; we're trying to establish a presence......»»
Dynamics of skyrmion spin states confirmed in neutron-scattering experiments
RIKEN researchers have brought low-energy devices based on spintronics one step closer, by measuring the dynamics of tiny magnetic vortices......»»
Unlocking the secrets of spin with high-harmonic probes
Deep within every piece of magnetic material, electrons dance to the invisible tune of quantum mechanics. Their spins, akin to tiny atomic tops, dictate the magnetic behavior of the material they inhabit. This microscopic ballet is the cornerstone of.....»»
Some of the moon"s craters are from interstellar impacts. Can we tell which?
By discovering two interstellar objects (ISOs), we know that asteroids and comets from other star systems pass through the solar system from time to time. By inference, some of these must have crashed into the moon, creating impact craters. If we cou.....»»
Endangered thick-billed parrots at risk of losing unprotected Sierra Madre forest habitats to logging, deforestation
A binational team of scientists, using creativity and innovation, adorned dozens of endangered thick-billed parrots with tiny solar-powered satellite transmitters to track and reveal their winter migratory nesting sites in the remote treetops of the.....»»
Astronomers discover how tiny dwarf galaxies form ‘fossils’
When tiny dwarf galaxies age and begin to erode away, they can transform into an even smaller and more dense shape, called an ultra-compact dwarf galaxy......»»
