Swarms of orbiting sensors could map an asteroid"s surface
It seems like every month a new story appears announcing the discovery of thousands of new asteroids. Tracking these small body objects from ground and even space-based telescopes helps follow their overall trajectory. But understanding what they're.....»»
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.....»»
Ocean salinity affects Earth"s climate—how about on exoplanets?
There's a link between Earth's ocean salinity and its climate. Salinity can have a dramatic effect on the climate of any Earth-like planet orbiting a sun-like star. But what about exoplanets around M-dwarfs?.....»»
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......»»
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.....»»
An asteroid wiped out the dinosaurs, not a comet, new study finds
Analysis of ruthenium isotopes showed the impactor was a carbonaceous-type asteroid. Enlarge / Artist impression of a large asteroid impacting on Earth, such as the Chicxulub event that caused the end-Cretaceous mass extinction 6.....»»
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......»»
Transforming satellite imagery: Innovative fusion method for precision agriculture
Remote sensing plays a vital role in monitoring agricultural landscapes, yet current satellite sensors often struggle with the trade-off between spatial and temporal resolution......»»
Tracking a newly discovered hypervelocity star spotted by citizen scientists
It may seem like the sun is stationary while the planets in its orbit are moving, but the sun is actually orbiting around the Milky Way galaxy at an impressive rate of about 220 kilometers per second—almost half a million miles per hour......»»
NASA shuts down asteroid-hunting telescope, but a better one is on the way
The NEOWISE spacecraft is on a course to fall out of orbit in the next few months. Enlarge / Artist's illustration of NASA's Wide-field Infrared Survey Explorer spacecraft. (credit: NASA/JPL-Caltech) Last week, NASA deco.....»»
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.....»»
A hopper could explore more than 150 km of Triton"s surface in two years
Neptune's largest moon, Triton, is one of the most biologically interesting places in the solar system. Despite being hard to reach, it appears to have active volcanoes, a thin atmosphere, and even some organic molecules called tholins on its surface.....»»
Novel anemometer tracks sound travel for speedier, more precise wind speed calculations on Mars
Mars has a notoriously inhospitable environment, with temperatures that fluctuate dramatically over the course of a Martian day and average minus 80 degrees Fahrenheit. Its surface is mostly covered in red dust, with terrain typified by craters, cany.....»»
A new robotic platform to reproduce and study complex ciliary behavior
Cilia are sensory structures extending from the surface of some cells. These hair-like structures are known to contribute to the sensorimotor capabilities of various living organisms, including humans......»»
