Circularly polarized light has properties that make it useful in a growing range of technologies, from next-generation 3D displays to bioimaging tools that can detect signals deep within living tissues. One way to produce this kind of light is with the help of chiral
The comet that rambled past us from another star last year likely originated in a cold, isolated corner of the galaxy that had yet to gel into its own solar system, astronomers reported Thursday.
Scientists from Trinity and Technical University of Denmark have developed a new radar-based technique that could address a critical gap in global conservation efforts, by transforming how we identify and track the insects that are actually responsible for pollinating plants.
We replaced the stove with plywood, turning the kitchen of the dive boat into an impromptu research lab. Plugging in wires and connecting tubing, we assembled a scientific instrument within the cramped cabin. Then we cast off into Halifax Harbor, Canada, surveying the turquoise
Ganymede is not only Jupiter's largest moon, but also the largest in our solar system and one of the few that hosts a massive ice ocean. Adding to this planet-like moon's uniqueness is the fact that among the hundreds of moons in our solar system, Ganymede is the only one that
Astronomers using the James Webb Space Telescope have made a surprising discovery about a galaxy long, long ago and far, far away: It isn't rotating. That's something only seen in the most massive, mature galaxies that are closer to us in space and time, said Ben Forrest, a
For the first time, scientists have measured the instantaneous mind-blowing power of jets blasting from a black hole.
Artificial intelligence can dramatically speed up the painstaking work of tracking wildlife with remote cameras, cutting analysis time from months or even a year to just days while producing nearly the same scientific conclusions as humans.
When you hear the term "food insecurity," what do you imagine? Do you equate it with poor dietary practices—in other words, eating badly? And do you believe the solution is getting people to better plan, shop for and prepare healthy meals?
Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to belong to one of two categories — bosons or fermions — but researchers have now shown that bizarre “in-between” particles called anyons could also exist in
For more than a decade, conservation biologist Steve Boyes searched for "ghost elephants"—nocturnal giants rumored to roam a remote, high-altitude wetland in eastern Angola. When a motion-sensor camera finally captured their image in 2024, Boyes turned to Stanford scientists
A new study shows that listening to your own favorite workout music can dramatically boost endurance. Cyclists exercising with self-selected songs lasted nearly 20% longer than when riding in silence, yet they didn’t feel more exhausted at the end. Researchers say music may
NASA's Psyche spacecraft will get a boost from Mars on Friday, May 15, passing just 2,800 miles (4,500 kilometers) from the planet's surface at some 12,333 mph (19,848 kph). The spacecraft will harness the planet's gravitational pull to speed up and adjust its trajectory toward
This week, researchers reported that the human brain is capable of sophisticated language processing while in an unconscious state during general anesthesia. An informatics and computing professor found that the Climate TRACE consortium has underestimated vehicle carbon
If you're dealing with a relationship marked by conflict, criticism or manipulation—be it with a parent, co-parent or colleague—chances are you've come across the "gray rock" method on social media or advice blogs.
Scientists may have found a smarter, safer way to wipe out termites hiding inside homes. A chemical called bistrifluron prevents drywood termites from forming new exoskeletons during molting, killing entire colonies from within. In tests, it eliminated about 95% of termites
A single-atom platinum catalyst lights ammonia at 200 °C and keeps it burning steadily at 1,100 °C with low NOx, generating high-grade, carbon-free heat for steel, cement and chemicals.
Mini models of the uterus lining give insight into mystery of how it is shed without scarring
Fur seals may look like they’re simply resting after exhausting hunting trips at sea, but their bodies are secretly working overtime. Scientists discovered that hours after returning to land, the seals’ heart rates suddenly surge — sometimes doubling — as they recover from the
Universities that run the National Center for Atmospheric Research want to keep it from being dismantled
Lindy Elkins-Tanton, principal investigator of NASA’s Psyche mission, explains in her new book how lessons from interplanetary exploration can help people solve problems together
Scientists in China discovered that ancient humans were making surprisingly advanced stone tools during a harsh ice age 146,000 years ago. The tools, created by Homo juluensis, show careful planning and complex thinking rather than simple stone-chipping. Researchers dated the
Seasonal models are predicting an El Niño climate pattern that could be the strongest on record, bringing with it more extreme weather.
One night last fall, University of Cincinnati astrophysics graduate Paul Smith waited anxiously for data to start rolling across his computer screen from the James Webb Space Telescope a million miles from Earth.
Researchers have developed a sensor about the size of a grain of rice that can measure forces and twisting motions in all directions using light instead of traditional electronics. The new sensor could help robotic tools and medical devices "feel" what they are touching,
From seasonal farmhands to health care workers to high-level software analysts, immigrant workers play a significant role in companies and industries across Canada and around the globe.
If a key ocean current collapses it could plunge northern Europe into a big freeze. Now researchers are weighing up a drastic intervention – building a 130-kilometre-wide dam between the US and Russia
Scientists studying axolotls, zebrafish, and mice have uncovered a shared set of genes that may one day help humans regrow lost limbs. By identifying powerful “SP genes” involved in regeneration, researchers discovered that disabling these genes stopped proper bone regrowth in
Imagine being tasked with counting every blade of grass in a field, noting every single species as you go. This is not far from the challenge many scientists face when analyzing microscopic samples packed with thousands of tiny particles.
What's the link between the global economy and the climate? Consumption drives extraction and carbon emissions. But there is more. The inequalities of the global economy don't just shape what goes into the atmosphere. They affect our understanding of the climate and our
When Cyclone Gabrielle tore through New Zealand's Tairāwhiti region in 2023, it left behind more than silt and floodwaters.
A study published in the Journal of Island and Coastal Archaeology has identified the earliest evidence of prehistoric occupation by island dwellers of northern Sri Lanka. Long thought to be unsuitable for human occupation due to its scarce stone resources and semi-arid
Scientists have uncovered a surprising secret hidden inside fat cells that could reshape how we think about obesity and metabolic disease. A protein called HSL, long believed to simply release stored fat when the body needs energy, turns out to have a second job deep inside the
The European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) have signed a Memorandum of Cooperation to deepen collaboration in planetary defense, alongside a dedicated agreement for collaboration on the Rapid Apophis Mission for Space Safety (Ramses) to
