New research is challenging one of medicine’s oldest assumptions: that cancer must be attacked to be cured. By treating glioblastoma patients with a simple combination of resveratrol and copper, the researchers found dramatic reductions in tumor aggressiveness, cancer biomarkers, immune checkpoints, and stem-cell–related markers—all without side effects. Their approach focuses on “healing” tumors by eliminating harmful cell-free chromatin particles released from dying cancer cells, which normally inflame an Read more ›

People who smoke only a couple of cigarettes a day still face surprisingly high risks of heart problems and early death. A large review of long-term studies shows that even very light smokers can see their risk of heart failure climb sharply. While quitting leads to major health improvements, some risk remains for decades. The safest approach is quitting entirely, especially at younger ages. Read more ›

Researchers uncovered how estrogen subtly reshapes learning by strengthening dopamine reward signals in the brain. Rats learned faster when estrogen levels were high and struggled when the hormone’s activity was blocked. The findings help explain how hormonal cycles influence cognitive performance and psychiatric symptoms. This connection offers a new path for understanding brain disorders tied to dopamine.

A massive real-world study comparing tirzepatide and semaglutide reveals both drugs deliver strong, early cardiovascular protection—reducing heart attack, stroke, and death in adults with type 2 diabetes. While companies have claimed large differences favoring their own medications, researchers found only modest distinctions between the two blockbuster GLP-1 drugs. Read more ›

Researchers discovered that the common amino acid arginine can block harmful Aβ aggregation and reduce its toxic effects in Alzheimer’s disease models. In flies and mice, oral arginine lowered plaque levels, reduced inflammation, and improved behavior. Its strong safety record and low cost make it a promising repurposing candidate. The findings hint at a surprisingly simple path toward more accessible AD therapies. Read more ›

Researchers discovered that chemotherapy can accidentally trigger a stress alarm in immune cells, causing inflammation that damages nerves. Blocking this alarm protected mice from nerve pain and kept their nerves healthier. A drug already being tested for cancer may help do the same in people. Early blood tests suggest it may even be possible to predict who will develop these symptoms before they happen. Read more ›

Scientists have traced kissing back to early primates, suggesting it began long before humans evolved. Their analysis points to great apes and even Neanderthals sharing forms of kissing millions of years ago. The behavior appears to have persisted through evolution as a social or bonding tool. Yet its patchy presence across human cultures hints at a mix of biology and cultural invention. Read more ›

Scientists used CRISPR to boost the efficiency and digestibility of a fungus already known for its meatlike qualities. The modified strain grows protein far more quickly and with much less sugar while producing substantially fewer emissions. It also outperforms chicken farming in land use and water impact.

New observations show that asteroid 1998 KY26 is a mere 11 meters across and spinning twice as fast as previously thought. The discovery adds complexity to Hayabusa2’s 2031 mission but also heightens scientific interest. The asteroid’s composition remains uncertain, making the encounter even more compelling. Insights from this work could improve future asteroid-defense and exploration efforts. Read more ›

Scientists have directly measured the minuscule electron sharing that makes precious-metal catalysts so effective. Their new technique, IET, reveals how molecules bind and react on metal surfaces with unprecedented clarity. The insights promise faster discovery of advanced catalysts for energy, chemicals, and manufacturing. Read more ›

Researchers have discovered a way to store information using a rare class of materials called ferroaxials, which rely on swirling electric dipoles instead of magnetism or charge. These vortex-like states are naturally stable and resistant to outside interference, but until now were almost impossible to control. By using circularly polarized terahertz light, scientists were able to flip these tiny rotational patterns on command, opening the door to a new form... Read more ›

A cutting-edge approach to immunotherapy shows that forcing cancer cells to die through necroptosis can dramatically boost the body's anti-tumor defenses. By combining three existing drugs, scientists reprogrammed malignant B cells so they release danger signals that rally immune cells to fully eliminate leukemia in preclinical models. Read more ›

Researchers created a dissolvable microneedle patch that delivers IL-4 directly to damaged heart tissue, jump-starting repair after a heart attack. The targeted approach shifts immune cells into a healing mode while improving communication between heart muscle and blood vessel cells. It avoids the systemic risks of IL-4 injections and shows promise for future minimally invasive treatment. Read more ›

Scientists confirmed that West Coast transient killer whales actually form two separate groups split between inner and outer coastal habitats. Inner-coast whales hunt smaller prey in shallow, maze-like waterways, while outer-coast orcas pursue large marine mammals in deep offshore canyons. The groups rarely interact, despite sharing a broad range along the Pacific Coast. Their contrasting lifestyles highlight the need for distinct conservation strategies. Read more ›

New climate modeling shows that heatwaves will keep getting hotter, longer, and more frequent for centuries—even after the world hits net-zero emissions. Delays of just a few years dramatically increase the likelihood of extreme, once-rare heat disasters, especially for countries near the equator. The research reveals that even reaching net zero by mid-century won't reverse the trend, and some regions will continue to see worsening heatwaves for a thousand years. Read more ›

Scientists may finally be closing in on the origins of two colossal, mysterious structures buried nearly 1,800 miles inside Earth—hidden formations that have puzzled researchers for decades. New modeling suggests that slow leakage of elements from Earth’s core into the mantle prevented the planet from developing strong chemical layers after its primordial magma-ocean era. Read more ›

Researchers have launched the first coordinated plan to protect microbial biodiversity, calling attention to the “invisible 99% of life” that drives essential Earth systems. The IUCN has formally recognized this effort through the creation of the Microbial Conservation Specialist Group. By developing new metrics, policies, and restoration tools, scientists aim to make microbial life a core part of global conservation action. The roadmap also outlines upcoming goals such as microbial... Read more ›

Researchers have recreated a miniature human bone marrow system that mirrors the real structure found inside our bones. The model includes the full mix of cells and signals needed for blood production and even maintains this process for weeks. It could transform how scientists study blood cancers and test new drugs. In the future, it may support more personalized treatment strategies. Read more ›

New research shows that light’s magnetic field is far more influential than scientists once believed. The team found that this magnetic component significantly affects how light rotates as it passes through certain materials. Their work challenges a 180-year-old understanding of the Faraday Effect and opens pathways to new optical and magnetic technologies. Read more ›
