What is the best radiation shielding for the surface of Mars?
The planet Mars is calling to us. At least, that is the impression one gets when examining all the planned and proposed missions to the red planet in the coming decade. With so many space agencies currently sending missions there to characterize its.....»»
Plasmonic modulators could enable high-capacity space communication
Researchers have achieved data rates as high as 424Gbit/s across a 53-km turbulent free-space optical link using plasmonic modulators—devices that use special light waves called surface plasmon polaritons to control and change optical signals. The.....»»
Witness 1.8 billion years of tectonic plates dance across Earth"s surface in a new animation
Using information from inside the rocks on Earth's surface, we have reconstructed the plate tectonics of the planet over the last 1.8 billion years......»»
NASA sets Europa Clipper launch date, despite Jupiter’s radiation concerns
Following a series of tests to determine the Europa Clipper’s ability to withstand radiation, NASA has finally approved a launch date: October 10. Though an … The post NASA sets Europa Clipper launch date, despite Jupiter’s radiation co.....»»
Lenovo’s version of the Surface Pro is on sale for $270
The Lenovo Tab P11 Gen 2, a much cheaper alternative to the Microsoft Surface Pro 9, delivers the same versatility for only $270 after Lenovo's $100 discount......»»
NASA"s Hubble, MAVEN help solve the mystery of Mars"s escaping water
Mars was once a very wet planet, as is evident in its surface geological features. Scientists know that over the last 3 billion years, at least some water went deep underground, but what happened to the rest? Now, NASA's Hubble Space Telescope and MA.....»»
Groundwater use can be accurately monitored with satellites using remote sensing platform, new study finds
Drought is a widespread concern in the Western U.S., and water managers across the region are developing groundwater management plans to conserve the essential resource. Groundwater is often pumped to the surface to irrigate crops, and meters that me.....»»
Decoding the language of cells with the power of proteomics
Hundreds of millions of years ago, single cells joined forces to become multicellular organisms. At the foundation of this multicellular world is the cell surface: the plasma membrane surrounding each cell, where individual units meet and communicate.....»»
Unlocking oceanic mysteries: Satellites shed light on aerosol layer height
Aerosol layer height (ALH) is a key parameter for assessing aerosol impacts on weather, climate, and atmospheric correction. Accurate ALH retrieval improves the understanding of aerosol-cloud interactions and aids in surface air quality monitoring......»»
The Moon had volcanic activity much more recently than we knew
Eruptions seem to have continued long after widespread volcanism had ended. Enlarge / The eruptions that produced the dark mare on the lunar surface ended billions of years ago. (credit: NASA/GSFC/Arizona State University).....»»
The Earth"s inner core is an enduring mystery: Here"s how researchers are starting to solve it
Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core—a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the surface. In fact, without it we'd be unlikely to even exi.....»»
NOAA shares first data from GOES-19 SEISS instrument
The Space Environment In-Situ Suite (SEISS) instrument onboard NOAA's GOES-19 satellite is now sending radiation data back to Earth......»»
Microsoft"s Copilot+ gaming fail could be a big Apple Silicon win
Microsoft's push into AI-centric notebooks isn't great for gamers, as they can't play most of their games on the ARM-based chips inside the latest Copilot+ PCs. This is a problem that will be beneficial to Apple Silicon gaming.Microsoft Surface Lapto.....»»
Scientists uncover hidden source of snow melt: Dark brown carbon
Wildfires leave potent climate heaters behind in their wake, particles that enhance the absorption of sunlight and warm the atmosphere. Dropped on snow like a wool poncho, these aerosols darken and decrease the surface reflectance of snowy places......»»
Bioengineers develop protein assembly road map for nature-derived nanobubbles
As far as water gear goes, floaties are not exactly high tech. But the tiny air-filled bubbles some microorganisms use as flotation devices when they compete for light on the water surface are a different story......»»
NASA mission gets its first snapshot of polar heat emissions
NASA's newest climate mission has started collecting data on the amount of heat in the form of far-infrared radiation that the Arctic and Antarctic environments emit to space. These measurements by the Polar Radiant Energy in the Far-Infrared Experim.....»»
Apple stuck between a rock and a hard place tackling nonconsensual porn generators
Apple seems unable to stop influx of so-called "dual use" apps that look innocent on the surface but help users create deepfake porn — at a steep price.Altered image found in face swap adApple takes pride in regulating the App Store, and part of th.....»»
Observatory reveals key evidence of cosmic ray acceleration limit in W51 for first time
The Large High Altitude Air Shower Observatory (LHAASO) officially released the precise measurements of high-energy gamma radiation from the W51 complex, confirming it as a cosmic-ray accelerator boosting particles up to so-called ultra-high energies.....»»
Shedding light on the mechanism of yeast DNA repair
DNA damage is a cellular phenomenon that introduces structural abnormalities in double-stranded DNA. External factors, such as radiation or chemical agents, as well as internal factors, such as blocked DNA replication, can generate double-strand brea.....»»
New knowledge about cell receptors paves the way for future drugs against intestinal tumors
A new study from Karolinska Institutet published in Nature Communications provides valuable insights into the activation of receptors on the cell surface. The knowledge could lead to new targeted therapies and drugs against intestinal tumors, among o.....»»
Using atomic excitations to measure the rotation of spacetime
How would atoms behave near a supermassive object? We know how atoms behave in extremely weak gravity like that at the Earth's surface: They can be excited from a lower energy level to a higher one when an electron absorbs a photon or a nucleus absor.....»»
