U.S. Census data shows no systematic age differences between men and women in the workforce over the past decade. And globally, women on average live about five years longer than men. But that's not what you'll see if you search Google or YouTube or query an AI like ChatGPT.

Cornell researchers have built a programmable optical chip that can change the color of light by merging photons, without requiring a new chip for new colors.

Combing through 20 years of images from the European Space Agency's Mars Express and ExoMars Trace Gas Orbiter spacecraft, scientists have tracked 1,039 tornado-like whirlwinds to reveal how dust is lifted into the air and swept around Mars's surface.

Scientists can now receive near-real-time alerts about the world's lands as their surfaces change, thanks to a new satellite-based monitoring system described today in Nature Communications.

Every time you check the time on your phone, make an online transaction, or use a navigation app, you are depending on the precision of atomic clocks.

In recent years, NASA's Parker Solar Probe has given us a close-up look at the sun. Among the probe's revelations was the presence of numerous kinks, or "switchbacks," in magnetic field lines in the sun's outer atmosphere. These switchbacks are thought to form when solar magnetic field lines that point in opposite directions break and then snap together, or "reconnect," in a new arrangement, leaving telltale zigzag kinks in the reconfigured lines.

Over the past decade, experts in the field of nanotechnology and materials science have been trying to devise architectures composed of small structures that spontaneously arrange themselves following specific patterns. Some of these architectures are based on so-called icosahedral shells, structures with 20 different triangular phases that are symmetrically organized.

For decades, it's been known that subtle chemical patterns exist in metal alloys, but researchers thought they were too minor to matter—or that they got erased during manufacturing. However, recent studies have shown that in laboratory settings, these patterns can change a metal's properties, including its mechanical strength, durability, heat capacity, radiation tolerance, and more.

A Northwestern University-led team of astronomers has captured the most detailed glimpse yet of a doomed star before it exploded. Using NASA's James Webb Space Telescope (JWST), the international team identified a supernova's source star, or progenitor, at mid-infrared wavelengths for the first time. These observations—combined with archival images from the Hubble Space Telescope—revealed the explosion came from a massive red supergiant star, cloaked in an unexpected shroud of dust.

Researchers at University of Tsukuba have developed DeMemSeg, an AI-powered analysis pipeline that addresses a long-standing challenge in microscopy: precisely segmenting and measuring individual cell membranes that overlap in two-dimensional (2D) projection images. This innovation is expected to accelerate research on cellular mechanisms and related diseases.

A new study co-led by the University of Oxford and Google Cloud has shown how general-purpose AI can accurately classify real changes in the night sky—such as an exploding star, a black hole tearing apart a passing star, a fast-moving asteroid, or a brief stellar flare from a compact star system—and explain its reasoning, without the need for complex training.

Scanning forests with lasers can provide three-dimensional models of forests, creating a unique way to look at these ecosystems. Researchers at the University of Helsinki are pioneers in applying this technical solution to measuring ecosystems.

Despite rapid advances in reading the genetic code of living organisms, scientists still face a major challenge today—knowing a gene's sequence does not automatically reveal what it does. Even in simple, well-studied bacteria like Escherichia coli (better known as E. coli), about one-quarter of the genes have no known function. Traditional approaches—turning off one gene at a time and studying the effects—are slow, laborious, and sometimes inconclusive due to gene redundancy.

As Moscow's military offensive grinds on at Europe's eastern edge, tensions are skyrocketing on the continent due to repeated, brazen violations of European airspace deliberately orchestrated by Russia. Europe has announced counter-measures, in the form of a "drone wall" to combat this new threat.

Rice University researchers, in collaboration with international partners, have developed the first eco-friendly technology to rapidly capture and destroy toxic "forever chemicals" (PFAS) in water. The findings, recently published in Advanced Materials, mark a major step toward addressing one of the world's most persistent environmental threats.

A University of Sydney student has developed a completely new way to peer inside coral fossils to recover lost records of past climate change.

A now-fixed security flaw in India's income tax e-filing portal exposed millions of taxpayers' personal and financial data due to a basic IDOR vulnerability that let users view others' records by swapping PAN numbers. "The exposed data included full names, home addresses, email addresses, dates of b...

In research that could improve weather forecasting and winter driving safety, a University of Michigan-led study distinguished nine distinct precipitation types—varieties of rain, snow and mixed-phase (e.g., sleet)—using unsupervised machine learning and nearly a decade's worth of high-speed camera data. The research is published in Science Advances.

An anonymous reader quotes a report from 404 Media: Sora 2, Open AI's new AI video generator, puts a visual watermark on every video it generates. But the little cartoon-eyed cloud logo meant to help people distinguish between reality and AI-generated bullshit is easy to remove and there are half a ...

A team of researchers at the Ming Hsieh Department of Electrical and Computer Engineering has created a new breakthrough in photonics: the design of the first optical device that follows the emerging framework of optical thermodynamics.

Longtime Slashdot reader schwit1 shares a report from Reuters: OpenAI said on Tuesday it has banned several ChatGPT accounts with suspected links to the Chinese government entities after the users asked for proposals to monitor social media conversations. In its latest public threat report (PDF), Op...

A few years ago, researchers in Michal Lipson's lab noticed something remarkable. They were working on a project to improve LiDAR, a technology that uses lightwaves to measure distance. The lab was designing high-power chips that could produce brighter beams of light.

A new study has challenged a popular explanation for the unexpected 30-second shortening of Dimorphos's orbital period. The researchers found that the proposed mechanism would actually produce the opposite effect, given the gravitational dynamics of the small moon. The paper has been accepted for publication in Astronomy & Astrophysics and is currently available on the arXiv preprint server.

Neutrinos are very common fundamental particles included in the Standard Model of particle physics. Measuring their properties allows for creating more accurate models of the birth of the universe, the life of stars and the interactions between fundamental particles. Some of the open questions include the absolute mass of the neutrino and whether neutrinos are their own antiparticles.

For years, researchers have puzzled over how the ancient people of Rapa Nui did the seemingly impossible and moved their iconic moai statues. Using a combination of physics, 3D modeling and on-the-ground experiments, a team including faculty at Binghamton University, State University of New York, has confirmed that the statues actually walked—with a little rope and remarkably few people.
