Fossils from Qatar have revealed a small, newly identified sea cow species that lived in the Arabian Gulf more than 20 million years ago. The site contains the densest known collection of fossil sea cow bones, showing that these animals once thrived in rich seagrass meadows. Their ecological role mirrors that of modern dugongs, which still reshape the Gulf’s seafloor as they graze. The findings may help researchers understand how seagrass ecosystems respond to long-term environmental change.

Researchers found that eroded lava rubble beneath the South Atlantic can trap enormous amounts of CO2 for tens of millions of years. These porous breccia deposits store far more carbon than previously sampled ocean crust. The discovery reshapes how scientists view the long-term balance of carbon between the ocean, rocks, and atmosphere. It also reveals a hidden mechanism that helps stabilize Earth’s climate over geological timescales.

Long COVID still affects people worldwide with stubborn symptoms like fatigue and cognitive issues. A clinical trial tested whether boosting NAD+ using nicotinamide riboside could help. Although overall group differences were limited, many participants showed encouraging improvements after taking NR for at least 10 weeks. The findings suggest NAD+ enhancement may offer symptom relief for some individuals.

Researchers discovered that nerve injuries can alter the immune system throughout the body, and males and females react very differently. Male mice showed strong inflammatory responses, while females showed none, yet both transmitted pain-inducing signals through their blood. These findings reveal previously unknown pathways driving pain, especially in females. The work points toward new opportunities for personalized chronic pain therapies.

A sudden, unexplained mass die-off is decimating sea urchins around the world, including catastrophic losses in the Canary Islands. Key reef-grazing species are reaching historic lows, and their ability to reproduce has nearly halted in some regions. Scientists suspect a pathogen but haven’t yet confirmed the culprit. The fate of these reefs may hinge on solving this unfolding pandemic.

Rats with naturally high stress levels were far more likely to self-administer cannabis when given access. Behavioral testing showed that baseline stress hormones were the strongest predictor of cannabis-seeking behavior. Lower cognitive flexibility and low endocannabinoid levels also contributed to increased use. The results hint at possible early indicators of vulnerability to drug misuse.

Researchers found that both how often and how much someone drinks significantly shape their cancer risk, even at moderate levels. Vulnerability varies across groups, with genetics, socioeconomic status, obesity, and lifestyle behaviors amplifying harm. The review also uncovered gender differences, beverage-specific risks, and biological pathways that intensify cancer development.

A cutting-edge therapy using base-edited immune cells is offering a major breakthrough for patients with one of the toughest forms of blood cancer, T-cell acute lymphoblastic leukaemia. By precisely rewriting tiny sections of DNA, scientists at UCL and Great Ormond Street Hospital created universal CAR T-cells capable of targeting the cancer without harming themselves—a long-standing challenge in T-cell–based therapies. Early trial results show deep, long-lasting remissions, including in patients who had exhausted standard treatment options.

Scientists discovered that the protein RPA plays a critical and previously unconfirmed role in stimulating telomerase to maintain long, healthy telomeres. When RPA malfunctions, telomeres can shorten dangerously, leading to serious diseases.

Scientists tracking young Arizona Bald Eagles found that many migrate north during summer and fall, bucking the traditional southbound pattern of most birds. Their routes rely heavily on historic stopover lakes and rivers, and often extend deep into Canada. As the eagles mature, their flights become more precise, but they also encounter significant dangers like electrocution and poisoning. These discoveries point to the need for targeted conservation of critical travel corridors.

A new economic modeling tool is helping Maine kelp farmers identify cost-saving strategies with remarkable precision. By analyzing farm design, weather, vessel types, and processing methods, it highlights how decisions ripple through overall profitability. When tested, the tool demonstrated that simple redesigns and mechanization could dramatically reduce production costs. Its findings could reshape the future of offshore kelp farming.

Scientists developed a high-performance hydrogen-production catalyst using lignin, a common waste product from paper and biorefinery processes. The nickel–iron oxide nanoparticles embedded in carbon fibers deliver fast kinetics, long-term durability, and low overpotential. Microscopy and modeling show that a tailored nanoscale interface drives the catalyst’s strong activity. The discovery points toward more sustainable and industrially scalable clean-energy materials.

Scientists have uncovered that some atoms in liquids don't move at all—even at extreme temperatures—and these anchored atoms dramatically alter the way materials freeze. Using advanced electron microscopy, researchers watched molten metal droplets solidify and found that stationary atoms can trap liquids in tiny “atomic corrals,” keeping them fluid far below their normal freezing point and giving rise to a strange hybrid state of matter.

Northwestern scientists have created the fastest-ever hepatitis C diagnostic, delivering accurate results in only 15 minutes. The test uses the DASH rapid PCR system, originally developed for COVID, but adapted for whole blood samples. Independent testing showed 100% agreement with existing commercial platforms. Its speed could transform how quickly patients begin treatment.

SACRAMENTO, CALIF.—Growth Energy, the nation’s largest biofuel trade association, welcomed news that California’s E15 Multimedia Working Group (MMWG) transmitted its Staff Written Summary to the California Environmental Policy Council (CEPC) today. The publication of the summary marks regulatory progress–an important step in the ongoing process of giving California drivers access to E15, a more affordable fuel option made with 15% ethanol that can be used in 96% of cars on the road today and that California approved for sale in October.

Growth Energy CEO Emily Skor issued the following statement in response:

“Californians deserve access to more affordable fuel options and that’s precisely what E15 would provide. We commend the Multimedia Working Group for its continued work and for taking the steps it needs to take to swiftly get E15 into the marketplace. We will continue to engage with the appropriate agencies, our members, and our retail partners to give California drivers access to lower-cost E15 as soon as possible.”

Critical minerals, such as copper, cobalt, and silicon, are vital for energy technologies, but most critical minerals markets are less transparent than mature energy markets, such as crude oil or coal. Like other energy markets, many supply-side and demand-side factors influence pricing for these energy-relevant critical minerals, but critical minerals supply chains contain numerous data gaps.

Researchers uncovered how shifting levels of a brain protein called KCC2 can reshape the way cues become linked with rewards, sometimes making habits form more quickly or more powerfully than expected. When this protein drops, dopamine neurons fire more intensely, strengthening new associations in ways that resemble how addictive behaviors take hold. Rat studies showed that even brief, synchronized bursts of neural activity can amplify reward learning, offering insight into why everyday triggers, like a morning routine, can provoke strong cravings.

Researchers have uncovered surprising evidence that the deep ocean’s carbon-fixing engine works very differently than long assumed. While ammonia-oxidizing archaea were thought to dominate carbon fixation in the sunless depths, experiments show that other microbes—especially heterotrophs—are doing far more of the work than expected. This discovery reshapes our understanding of how carbon moves through the deep ocean and stabilizes Earth’s climate.

Scientists discovered that certain cancer cells use a low-level activation of a DNA-dismantling enzyme—normally seen in cell death—to survive treatment. Instead of dying, these “persister cells” leverage this sublethal signal to regrow. Because the mechanism is non-genetic, it appears much earlier than typical resistance mutations. Targeting this enzyme could help stop tumors from returning.

Obesity accelerates the rise of Alzheimer’s-related blood biomarkers far more rapidly than previously recognized. Long-term imaging and plasma data show that obese individuals experience much faster increases in proteins linked to neurodegeneration and amyloid buildup. Surprisingly, blood tests detected these changes earlier than PET scans. The results point to obesity as a major, modifiable contributor to Alzheimer’s progression.
