A nationwide study found that recent colds caused by rhinoviruses can give short-term protection against COVID-19. Children benefit most, as their immune systems react strongly with antiviral defenses, helping explain their lower rates of severe illness.

Australian teachers are in crisis, with 9 in 10 experiencing severe stress and nearly 70% saying their workload is unmanageable. A major UNSW Sydney study found teachers suffer depression, anxiety, and stress at rates three to four times higher than the national average, largely driven by excessive administrative tasks. These mental health struggles are pushing many to consider leaving the profession, worsening the teacher shortage.

Painkillers we often trust — ibuprofen and acetaminophen — may be quietly accelerating one of the world’s greatest health crises: antibiotic resistance. Researchers discovered that these drugs not only fuel bacterial resistance on their own but make it far worse when combined with antibiotics. The findings are especially troubling for aged care settings, where residents commonly take multiple medications, creating perfect conditions for resistant bacteria to thrive.

Researchers uncovered that the Maui wildfires caused a spike in deaths far higher than reported, with hidden fatalities linked to fire, smoke, and lack of medical access. They warn that prevention rooted in Native Hawaiian ecological knowledge is critical to avoiding another tragedy.

A stunning discovery in North Greenland has reclassified strange squid-like fossils, revealing that nectocaridids were not early cephalopods but ancestors of arrow worms. Preserved nervous systems and unique anatomical features provided the breakthrough, showing these creatures once ruled as stealthy predators of the Cambrian seas. With complex eyes, streamlined bodies, and evidence of prey in their stomachs, they reveal a surprising past where arrow worms were far more fearsome than their modern descendants.

Living near the ocean may actually help you live longer. A new nationwide study found that people in coastal regions enjoy life expectancies a year or more above the U.S. average, while city dwellers near inland rivers and lakes may face shorter lifespans. Researchers suggest the difference comes from environmental and social factors—cleaner air, cooler summers, recreation opportunities, and higher incomes near the coasts versus pollution, poverty, and flood risks inland. The findings reveal that not all “blue spaces” are equal, challenging assumptions that any water view brings health benefits.

A chance glance at a museum display has led to the first-ever discovery of an ichthyosaur fossil in western Japan, dating back around 220 million years. Initially mistaken for a common bivalve fossil, the specimen was revealed to contain 21 bone fragments, including ribs and vertebrae, belonging to a rare Late Triassic ichthyosaur. Experts say this find could reshape understanding of ichthyosaur evolution and their ability to cross the vast Panthalassic Ocean.

Scientists at CERN’s ATLAS experiment have uncovered compelling evidence of Higgs bosons decaying into muons, an incredibly rare event that could deepen our understanding of how particles acquire mass. They also sharpened their ability to detect the even rarer Higgs decay into a Z boson and a photon—a process that might reveal hidden physics beyond the Standard Model.

Scientists using Google’s quantum processor have taken a major step toward unraveling the deepest mysteries of the universe. By simulating fundamental interactions described by gauge theories, the team showed how particles and the invisible “strings” connecting them behave, fluctuate, and even break. This breakthrough opens the door to probing particle physics, exotic quantum materials, and perhaps even the structure of space and time itself.

Physicists have built a novel superconducting platform that mimics hidden vortex states once thought unobservable. Their "backdoor" method overcomes experimental limits, letting them control quantum behavior on demand. The discovery could pave the way for powerful quantum simulators.

We forecast natural gas consumption in the United States will increase 1% to set a record of 91.4 billion cubic feet per day (Bcf/d) in 2025. In our latest Short-Term Energy Outlook, we expect natural gas consumption to increase across all sectors except for electric power, which had been the source of most natural gas consumption growth in the previous decade.

A large study of nearly 16,000 adults found no link between eating animal protein and higher death risk. Surprisingly, higher animal protein intake was associated with lower cancer mortality, supporting its role in a balanced, health-promoting diet.

Scientists have identified compounds that block bitter taste receptors activated by saccharin and acesulfame K. The most promising is (R)-(-)-carvone, which reduces bitterness without the cooling side effect of menthol, potentially making sugar-free products much more palatable.

UBC researchers revealed that gut bacteria can digest cellulose-based food thickeners, once thought indigestible, by using enzymes activated by natural dietary fibers. This discovery suggests these common additives may play a more active role in our nutrition than previously believed.

Scientists have discovered that electron spin loss, long considered waste, can instead drive magnetization switching in spintronic devices, boosting efficiency by up to three times. The scalable, semiconductor-friendly method could accelerate the development of ultra-low-power AI chips and memory technologies.

Researchers cracked the mystery of altermagnets, materials with no net magnetization yet strange light-reflecting powers, by creating a new optical measurement method. Their findings confirmed altermagnetism in an organic crystal and opened doors to innovative magnetic devices.

Defects in spintronic materials, once seen as limitations, may now be key to progress. Chinese researchers discovered that imperfections can enhance orbital currents, unlocking more efficient, low-power devices that outperform traditional approaches.

A Rochester team engineered a new type of solar thermoelectric generator that produces 15 times more power than earlier versions. By enhancing heat absorption and dissipation rather than tweaking semiconductor materials, they dramatically improved efficiency and demonstrated practical applications like powering LEDs.

Scientists have discovered that a gene called MUC19, inherited from Denisovans through ancient interbreeding, may have played a vital role in helping Indigenous ancestors adapt as they migrated into the Americas. Found at unusually high frequencies in both modern and ancient populations, the gene likely provided immune advantages against new pathogens. This research highlights how archaic DNA, passed through both Denisovans and Neanderthals, enriched human genetic diversity in ways that still shape us today.

Researchers uncovered that hypothalamic neurons safeguard blood sugar overnight by directing fat breakdown, preventing hypoglycemia during early sleep. This subtle control system may explain abnormal metabolism in prediabetes.
