Modeling Earth systems at a quintillion calculations per second
Climate models compute vast amounts of information about Earth's climate system—from small water droplets to large-scale weather patterns—to re-create past climate or predict future climate. Accurately re-creating how Earth's energy (measured in.....»»
Understanding bribery: Why people choose to give bribes
McGill-led researchers developed a model of the factors that go into citizens' calculations about whether to bribe officials, information that can help authorities fight corruption......»»
Scientists collect "microbial fingerprints" found in household plumbing
The plumbing systems in households can teem with generally harmless microbial life, but scientists have not had an opportunity to fully document the bacterial communities within people's homes......»»
New set of human rights principles aims to end displacement and abuse of Indigenous people
For more than a century, conservationists have worked to preserve natural ecosystems by creating national parks and protected areas. Today the Earth faces a global biodiversity crisis, with more than 1 million species at risk of extinction. This make.....»»
Mathematicians make leap in modeling human impact on climate
A breakthrough in the theory of climate change science has given scientists the most robust way yet to link observed climate change to both human-made and natural causes and to spot early warning signals for potential climate disasters......»»
Sentinel-1C captures first radar images of Earth
Less than a week after its launch, the Copernicus Sentinel-1C satellite has delivered its first radar images of Earth—offering a glimpse into its capabilities for environmental monitoring. These initial images feature regions of interest, including.....»»
Windows 11 can now run on unsupported systems, but there’s a catch
Microsoft is now allowing PC users to install Windows 11 on unsupported systems, though updates will have to be done manually......»»
Attackers actively exploiting flaw(s) in Cleo file transfer software (CVE-2024-50623)
Attackers are exploiting a vulnerability (CVE-2024-50623) in file transfer software by Cleo – LexiCo, VLTransfer, and Harmony – to gain access to organizations’ systems, Huntress researchers warned on Monday. “We’ve discover.....»»
Meet Hyperlight, Ars Technica’s new, even brighter “Light” mode
You asked, so we built it! Like many sites, apps, and operating systems, Ars Technica has both "Light" and "Dark" visual styles. They look great! But even the "Light" mode has dar.....»»
Plans to stabilize Earth"s climate rely on emerging carbon removal technology—we need to get moving, say researchers
Global carbon emissions from fossil fuels continue to rise and 2024 is likely to be the world's hottest year on record......»»
Jupiter will be at its biggest and brightest this weekend. Here’s how to see it
There's a special chance to see Jupiter in the sky this weekend as it comes closest to Earth......»»
Hybrid model links micro and macro scales in complex systems
In fields ranging from immunology and ecology to economics and thermodynamics, multi-scale complex systems are ubiquitous. They are also notoriously difficult to model. Conventional approaches take either a bottom-up or top-down approach. But in dist.....»»
Scientists urged to pull the plug on "bathtub modeling" of flood risk
Recent decades have seen a rapid surge in damages and disruptions caused by flooding. In a commentary article published in the journal Earth's Future, researchers at the University of California, Irvine and the University of Bristol in the United Kin.....»»
Record-low Antarctic sea ice can be explained and forecast months out by patterns in winds
Amid all the changes in Earth's climate, sea ice in the stormy Southern Ocean surrounding Antarctica was, for a long time, an odd exception. The maximum winter sea ice cover remained steady or even increased slightly from the late 1970s through 2015,.....»»
Unlike other insects, desert ants may use polarity of geomagnetic field for navigation
Desert ants of the Cataglyphis nodus species use the Earth's magnetic field for spatial orientation, but these tiny insects rely on a different component of the field than other insects, a research team led by Dr. Pauline Fleischmann from the Univers.....»»
Computer modeling shows close encounters between distant DNA regions cause bursts of gene activity
Researchers at Kyushu University have revealed how spatial distance between specific regions of DNA is linked to bursts of gene activity. Using advanced cell imaging techniques and computer modeling, the researchers showed that the folding and moveme.....»»
3 sci-fi movies on Peacock you need to watch in December 2024
Extraterrestrial life, a comet plummeting toward Earth, and memory erasure are in three sci-fi movies on Peacock you need to watch in December 2024......»»
Biodegradable polymers show promise for nutrient encapsulation and replacing microbeads in beauty products
Microplastics are an environmental hazard found nearly everywhere on Earth, released by the breakdown of tires, clothing, and plastic packaging. Another significant source of microplastics is tiny beads that are added to some cleansers, cosmetics, an.....»»
Building a robust security posture with limited resources
In this Help Net Security interview, Gareth Lindahl-Wise, CISO at Ontinue, discusses how business leaders can align innovation with cybersecurity, tackle the risks posed by legacy systems, and build defenses for startups. Lindahl-Wise also highlights.....»»
Two European satellites launch on mission to blot out the Sun—for science
This will all happen nearly 40,000 miles above the Earth, so you won't need your eclipse glasses. Two spacecraft developed by the European Space Agency launched on top of an India.....»»
3D scans of giant hailstones reveal surprising discoveries that could help predict future storms
Hailstones are formed during thunderstorms, when raindrops are propelled into very cold parts of a cloud, where they freeze. Once the particles are heavy enough, gravity pulls them back towards Earth. As they plummet, they grow into hailstones, which.....»»
