New view of North Star reveals spotted surface
Researchers using Georgia State University's Center for High Angular Resolution Astronomy (CHARA) Array have identified new details about the size and appearance of the North Star, also known as Polaris. The new research is published in The Astrophys.....»»
Novel ratchet mechanism uses a geometrically symmetric gear driven by asymmetric surface wettability
The ratchet mechanism is a fascinating energy-conversion system that converts disorderly or random motion into orderly, directed movement through a process known as spontaneous rectification. It is a critical component of mechanical systems, typicall.....»»
Apple wants to put touch screens on every MacBook Pro metal surface
Apple still won't make us a touch-screen Mac, but it is at least considering adding touch-sensitive displays on just about every surface that surrounds the MacBook Pro keyboard as the next best thing.Detail from the patent showing an image of a surpr.....»»
Climate change is already reshaping PNW shorelines: Tribal nations are showing how to adapt
Keeley Chiasson plodded through the steep, sandy sediment near the base of the bluff. Carefully perched on a firm shelf, she scraped back the weathered surface of the wall, revealing stripes of cocoa, rust and tan sediments......»»
Exoplanets may contain more water than previously thought
We know that the Earth has an iron core surrounded by a mantle of silicate bedrock and water (oceans) on its surface. Science has used this simple planet model until today for investigating exoplanets—planets that orbit another star outside our sol.....»»
Researchers develop nanoparticle array implantation for sensitive and reusable detection
Shanghai Jiao Tong University (SJTU) researchers have developed a highly sensitive and reusable surface-enhanced Raman spectroscopy (SERS) microfluidics system that has achieved a detection limit lower than 10 ppt (parts per trillion) of harmful subs.....»»
Modeling study reveals German lake conditions under climate change
Using long-term monitoring data from 46 German lakes, researchers from the Leibniz Institute of Freshwater Ecology and Inland Fisheries (IGB) in cooperation with the Helmholtz Center for Environmental Research in Magdeburg have shown that surface tem.....»»
Group-IB partners with SecurityHQ to enhance SOC capabilities
Group-IB announced the signing of a global partnership agreement with SecurityHQ, a global independent Managed Security Service Provider (MSSP). With this partnership, SecurityHQ will leverage Group-IB’s Threat Intelligence, Attack Surface Mana.....»»
Meteorites give the Moon its extremely thin atmosphere
Impacts that vaporize bits of the lunar surface maintain the Moon's thin atmosphere. Enlarge / Artist's rendition of the LADEE mission above the lunar surface. (credit: NASA/ Dana Berry) The Moon may not have much of an.....»»
Geophysicists find link between seismic waves called PKP precursors and strange anomalies in Earth"s mantle
For the decades since their discovery, seismic signals known as PKP precursors have challenged scientists. Regions of Earth's lower mantle scatter incoming seismic waves, which return to the surface as PKP waves at differing speeds......»»
TikTok ban: ByteDance says app is run and controlled in US, not China
ByteDance’s appeal against a US TikTok ban is underway, and the company has accused the Department of Justice of factual errors in presenting its case – intended to force the sale of the app to an American company. The DOJ says the app’s fee.....»»
A rarely seen deep sea fish is found in California, and scientists want to know why
A rarely seen deep sea fish resembling a serpent was found floating dead on the ocean surface off the San Diego coast and was brought ashore for study, marine experts said......»»
Research team releases a 76 m-per-pixel global color image dataset and map of Mars
Remote-sensing images of Mars contain rich information about its surface morphology, topography, and geological structure. These data are fundamental for scientific research and exploration missions of Mars. Prior to China's first Mars exploration mi.....»»
Researchers develop a test bed for separating valuable material on the moon
It's often better to flesh out technologies fully on Earth's surface before they're used in space. That is doubly true if that technology is part of the critical infrastructure keeping astronauts alive on the moon......»»
Climate model biases in global monsoon: Insights from interhemispheric energy transport
Global monsoon is a critical component of the global atmospheric circulation system. Variations in summer precipitation over the global monsoon region have large impacts on freshwater resources, which support about two-thirds of the world's populatio.....»»
Novel light transport model improves X-ray phase contrast imaging
Researchers at the University of Houston unveiled an advancement in X-ray imaging technology that could provide significant improvements in medical diagnostics, materials and industrial imaging, transportation security and other applications......»»
Researchers discover new way to purify liquid argon for neutrino experiments
Construction workers have finished the excavation of the huge caverns that will house the international Deep Underground Neutrino Experiment. While engineers and technicians are preparing for the installation of the gigantic neutrino detectors into t.....»»
New cobalt complex triggers ferroptosis in cancer cells
In programmed cell death, certain signaling molecules initiate a kind of suicide program to cause cells to die in a controlled manner. This is an essential step to eliminate damaged cells or to control the number of cells in certain tissues, for exam.....»»
Research team finds evidence of hydration on the asteroid Psyche
Using data from NASA's James Webb Space Telescope, a Southwest Research Institute-led team has confirmed hydroxyl molecules on the surface of the metallic asteroid Psyche. The presence of hydrated minerals suggests a complex history for Psyche, impor.....»»
