Martian winds can have quite an impact. ESA's Mars Express has spotted them whipping up sand grains and acting as a cosmic sandblaster, carving out intriguing grooves near Mars's equator.
For more than a century, scientists have wondered why physical structures like blood vessels, neurons, tree branches, and other biological networks look the way they do. The prevailing theory held that nature simply builds these systems as efficiently as possible, minimizing
It feels like every week now we're writing a new article about how 3I/ATLAS is not an alien technology. But it's worth reiterating, and perhaps taking a look at the methodology we used to prove that statement. A new paper, available in pre-print form on arXiv from Sofia Sheikh
In the last century, synthetic fertilizers have changed the face of the planet. The current world population might be halved if not for this useful development.
An international project investigating the form, content and consequences of online conspiracy theories has found that in German-speaking countries, such theories often originate locally and have come to form a complex ecosystem of alternative news websites, print media and
At 4 a.m., while most of New Jersey slept, a Princeton Plasma Physics Laboratory (PPPL) physicist sat at his computer connected to a control room 3,500 miles away in Oxford, England. Years of experience running fusion experiments in the U.S. helped guide the U.K. team through
Brain dead after a hard day of work? It turns out it's totally fine to park yourself in front of the TV. It might even make recovery—an essential part of burnout prevention—easier.
A new study on how U.S. defense attorneys think about autism and use strategies informed by neurodiversity in their work finds that attorneys saw autism through a medical lens and acknowledged the need for better ways to secure accommodations for their clients in court.
A new study has concluded that in New Jersey's largest city, crime was concentrated significantly around corner stores compared with other commercial venues. The study's findings have implications for crime prevention, urban planning, and community safety policies.
A new video shows the evolution of Kepler's Supernova Remnant using data from NASA's Chandra X-ray Observatory captured over more than two and a half decades.
Antiferromagnetic (AF) materials are made up of atoms or molecules with atomic spins that align in antiparallel directions of their neighbors. The magnetism of each individual atom or molecule is canceled out by the one next to it to produce zero net magnetization.

The riskiest behavior in humans peaks in adolescence. Researchers from the University of Michigan and James Madison University expected to find risky behavior to peak in adolescence in a study of chimpanzees as well. But instead, they found that chimpanzee infants take the
Across all domains of life, immune defenses foil invading viruses by making it impossible for the viruses to replicate. Most known CRISPR systems target invading pathogens' DNA and chop it up to disable and modify genes, heading off infections at the (cellular) pass.
Scientists at Nagoya University in Japan have identified the genes that allow an organism to switch between living as single cells and forming multicellular structures. This ability to alternate between life forms provides new insights into how multicellular life may have
An international research team reports the analysis of new hominin fossils from the site of Thomas Quarry I (Casablanca, Morocco). The fossils are very securely dated to 773,000 +/- 4,000 years ago, thanks to a high-resolution magnetostratigraphic record capturing in detail the
Thanks to the discovery of thousands of exoplanets to date, we know that planets bigger than Earth but smaller than Neptune orbit most stars. Oddly, our sun lacks such a planet. That's been a source of frustration for planetary scientists, who can't study them in as much detail
The wake left by Betelgeuse’s companion could solve a decades-old mystery of its strange brightness cycles.
Every January, offices quietly reset. New planners appear on desks. Fresh notebooks open in meetings. To-do lists look neater, ambitions clearer. There is a shared sense that this year, things will be different.
Much of south-eastern Australia is currently in the grip of a heat wave, which is expected to peak over the next two days. Heat waves often trigger bushfires, particularly if combined with strong winds.
Australia's climate is changing rapidly due to rising global greenhouse gas emissions. Extreme weather events such as tropical cyclones, east coast low pressure systems, flash floods, droughts, bushfires, severe storms, and both land and marine heat waves are becoming
Across Australia, forests are quietly changing. Trees that once stood for decades or centuries are now dying at an accelerating rate. And this is not because of fire, storms, or logging. The chronic stress of a warming climate is killing them.
What will we see in the southern sky in 2026? A total eclipse of the moon (at a convenient time), a blue moon and a supermoon, the two brightest planets close together, and Jupiter disappearing behind the moon in the daytime.
As Nairobi's skyline climbs ever higher, life for those living on the city's edges is being transformed—and not always for the better.
Can an organization ever be truly meritocratic? That's a question Emilio J. Castilla, the NTU Professor of Management at the MIT Sloan School of Management, explores in his new book, "The Meritocracy Paradox: Where Talent Management Strategies Go Wrong and How to Fix Them"
Scientists are a step closer to solving one of the universe's biggest mysteries as new research finds evidence that two of its least understood components may be interacting, offering a rare window into the darkest recesses of the cosmos.
Economics could do with less mathematics and more story, says Canada's most-cited economist.
Municipal bonds are a time-honored way to fund roads, schools, bridges and other public projects while paying investors interest, usually at tax-free rates.
For decades, flooding has remained one of the most destructive and deadly natural disasters in the United States, causing an average of $8 billion in damages and nearly 90 deaths each year.

In the aftermath of the giant asteroid that crashed into the Yucatan Peninsula about 66 million years ago, approximately 75% of all species on Earth were wiped out, including the dinosaurs. Among those thought to have perished at this K-Pg (Cretaceous-Paleogene) boundary were
The discovery of thousands more galaxies with stars ringing their main disks could help astronomers study galactic evolution more generally.
On clear days in Hartbeespoort, South Africa, satellite images often reveal a reservoir with shades of deep blue interrupted by drifting patches of vivid green. These shifting features indicate algae blooms, which can affect water quality, ecosystems, and nearby human
