Atmospheric oxidation and the creation of modern Mars
Like Earth, Mars was formed about 4.5 billion years ago, but its early surface was very different than today's. Mars' surface then had high rates of meteorite and asteroid impacts from the period known as the Late Heavy Bombardment. But whereas today.....»»
Researchers discover new isotope plutonium-227
A research team led by researchers at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS) has synthesized a new plutonium isotope, plutonium-227. Their study is published in Physical Review C......»»
Fossils and fires: Insights into early modern human activity in the jungles of Southeast Asia
Studying microscopic layers of dirt dug from the Tam Pà Ling cave site in northeastern Laos has provided a team of Flinders University archaeologists and their international colleagues with further insights into some of the earliest evidence of Homo.....»»
Polar jet stream could reveal Saturn"s rotational period
A hexagon-shaped atmospheric phenomenon first spotted on Saturn by Voyager 1 and Voyager 2 has intrigued scientists since the 1980s. More recently, NASA's Cassini mission has periodically observed the hexagon and its embedded strong eastward jet that.....»»

Frontegg launched Flows, a journey-time orchestration capability that uses generative AI to simplify the creation of advanced customer identity processes. As growing businesses emerge from startup mode and enter scale-up mode, their user identities s.....»»
Physics team uncovers a quantum Mpemba effect with a host of "cool" implications
Initially investigating out of pure curiosity, researchers have made a discovery that bridges the gap between Aristotle's observations two millennia ago and modern-day understanding, while opening the door to a whole host of "cool"—and "cooling"—.....»»
How a witch-hunting manual and social networks helped ignite Europe"s witch craze
The sudden emergence of witch trials in early modern Europe may have been fueled by one of humanity's most significant intellectual milestones: the invention of the printing press in 1450......»»
Nomad launches limited edition ‘Olde Dublin’ Horween leather Case and Folio for iPhone 16 Pro

‘Groups’ Underpin Modern Math. Here’s How They Work
What do the integers have in common with the symmetries of a triangle? In the 19th century, mathematicians invented groups as an answer to this question......»»
AI and quantum mechanics team up to accelerate drug discovery
Drug discovery is much like working a jigsaw puzzle. The chemical compounds behind drug molecules must be shaped to fit with the proteins in our bodies to produce therapeutic effects. That requirement for a meticulous fit means the creation of new dr.....»»
Perseverance team revives SHERLOC instrument to help with Jezero crater discovery
In January 2024, the SHERLOC instrument aboard NASA's Mars 2020 Perseverance rover encountered a significant issue. A fault in the instrument's motor caused the dust cover and autofocus mechanism to become inoperative, putting the rover's SHERLOC Ram.....»»
Curiosity rover provides new insights into how Mars became uninhabitable
NASA's Curiosity rover, currently exploring Gale crater on Mars, is providing new details about how the ancient Martian climate went from potentially suitable for life—with evidence for widespread liquid water on the surface—to a surface that is.....»»
New polymer design breaks the tradeoff between toughness and recyclability
Plastics underpin much of modern life—areas like medicine, technology, and food safety would be unrecognizable without plastics and their useful properties. However, the toughness of plastics, which is often desirable, also makes them a dangerous p.....»»
Nuclear rockets could travel to Mars in half the time, but designing the reactors that would power them isn"t easy
NASA plans to send crewed missions to Mars over the next decade—but the 140 million-mile (225 million-kilometer) journey to the red planet could take several months to years round trip......»»
Best practices for implementing threat exposure management, reducing cyber risk exposure
In this Help Net Security interview, Sanaz Yashar, CEO at Zafran, discusses the role of threat exposure management (TEM) in modern cybersecurity strategies. As traditional vulnerability management evolves, TEM addresses the overwhelming risks arising.....»»
Traces of antimatter in cosmic rays reopen the search for "WIMPs" as dark matter
One of the great challenges of modern cosmology is to reveal the nature of dark matter. We know it exists (it constitutes more than 85% of the matter in the universe), but we have never seen it directly and still do not know what it is......»»
A NASA Mars rover has a giant hole in one of its wheels
The wheels on NASA's Curiosity Mars rover are falling apart, but the plucky rover keeps on rolling......»»
New research uncovers how climate and soil shape tree and shrub wood density across ecosystems
An article published in Advances in Atmospheric Sciences has provided new insights into how wood density in trees and shrubs adapts to different climate and soil conditions. Led by Dr. Song Xiang from the Institute of Atmospheric Physics at the Chine.....»»
NASA"s laser comms demo makes deep space record, completes first phase
The Deep Space Optical Communications tech demo has completed several key milestones, culminating in sending a signal to Mars' farthest distance from Earth......»»
2-billion-year-old rock could help understand very early life on Earth and the hunt for evidence of life on Mars
Pockets of microbes have been found living within a sealed fracture in a 2-billion-year-old rock. The rock was excavated from the Bushveld Igneous Complex in South Africa, an area known for its rich ore deposits. This is the oldest example of living.....»»
