Pancreatic cancer is notoriously hard to treat, often resisting therapies that target its most common mutations. Researchers have now uncovered a hidden three-part loop that fuels tumor growth, involving the cancer drivers SRSF1, AURKA, and MYC. By targeting just one part of this loop with a specially designed molecule, they were able to shut down all three at once. The result was a dramatic loss of tumor cell survival, offering...

Astronomers have uncovered the long-hidden cause behind Betelgeuse’s strange behavior: a small companion star carving a visible wake through the giant’s vast atmosphere. Using nearly eight years of observations from NASA’s Hubble Space Telescope and ground-based observatories, scientists detected swirling trails of dense gas created as the companion, called Siwarha, moves through Betelgeuse’s outer layers.

Hubble has revealed a strange cosmic object called Cloud-9, a dark matter–dominated cloud with no stars at all. Scientists believe it is a “failed galaxy,” a leftover building block from the early Universe that never lit up. Its discovery confirms long-standing theories about starless galaxies. Cloud-9 offers a rare glimpse into the dark side of cosmic evolution. Read more ›

Sugar-loving mouth bacteria create acids that damage teeth, but arginine can help fight back. In a clinical trial, arginine-treated dental plaque stayed less acidic, became structurally less harmful, and supported more beneficial bacteria. These changes made the biofilms less aggressive after sugar exposure. The results point to arginine as a promising, natural addition to cavity-prevention strategies. Read more ›

Scientists at USC are launching a new trial to test a tiny stem cell implant that could restore vision in people with advanced dry macular degeneration. The hair-thin patch replaces damaged retinal cells responsible for sharp, central vision. Earlier studies showed the implant was safe and helped some patients see better. Researchers now hope it can deliver meaningful, lasting improvements in eyesight. Read more ›

A large genetic study shows that many people carry DNA sequences that slowly expand as they get older. Common genetic variants can dramatically alter how fast this expansion happens, sometimes multiplying the pace by four. Researchers also identified specific DNA expansions linked to severe kidney and liver disease. The findings suggest that age-related DNA instability is far more common than previously realized.

Foods that rely heavily on preservatives may be doing more than extending shelf life. In a large study spanning more than a decade, people with the highest intake of preservative additives were far more likely to develop type 2 diabetes. The increased risk appeared across many commonly used additives found in everyday processed foods. Researchers say the findings support advice to limit highly processed products when possible.

Researchers have developed a new class of antibodies that amplify the immune system’s ability to fight cancer. By clustering immune receptors that normally receive weak signals from tumors, these four-pronged antibodies push T cells into full attack mode. In early studies, they outperformed conventional antibodies at activating cancer-killing immune cells. The work opens the door to more effective immunotherapy treatments. Read more ›

Scientists in South Korea have discovered a way to make all-solid-state batteries safer and more powerful using inexpensive materials. Instead of adding costly metals, they redesigned the battery’s internal structure to help lithium ions move faster. This simple structural tweak boosted performance by up to four times. The work points to cheaper, safer batteries for phones, electric vehicles, and beyond. Read more ›

Stanford researchers have developed an AI that can predict future disease risk using data from just one night of sleep. The system analyzes detailed physiological signals, looking for hidden patterns across the brain, heart, and breathing. It successfully forecast risks for conditions like cancer, dementia, and heart disease. The results suggest sleep contains early health warnings doctors have largely overlooked. Read more ›

A new study finds that TikTok videos about gout frequently spread confusing or inaccurate advice. Most clips focus on diet changes and supplements, while barely mentioning the long-term treatments doctors say are essential for controlling the disease. Many videos also frame gout as a lifestyle problem, rather than a condition driven largely by genetics and underlying health factors. Researchers say the platform has huge potential—but only if accurate medical voices... Read more ›

A team of physicists has discovered a surprisingly simple way to build nuclear clocks using tiny amounts of rare thorium. By electroplating thorium onto steel, they achieved the same results as years of work with delicate crystals — but far more efficiently. These clocks could be vastly more precise than current atomic clocks and work where GPS fails, from deep space to underwater submarines. The advance could transform navigation, communications,...

DNA doesn’t just sit still inside our cells — it folds, loops, and rearranges in ways that shape how genes behave. Researchers have now mapped this hidden architecture in unprecedented detail, showing how genome structure changes from cell to cell and over time. These insights reveal why many disease-linked mutations outside genes can still cause harm. The findings could speed up the discovery of genetic risks and inspire new ways... Read more ›

Long COVID affects an estimated 65 million people worldwide and can damage the brain, heart, blood vessels, and immune system long after infection. Researchers now link symptoms to lingering virus, inflammation, micro-clots, and disrupted energy metabolism. While structured rehab and pacing can improve quality of life, a growing list of experimental treatments—from antivirals and metformin to microbiome therapies and biologics—shows early promise. Clear answers, however, are still limited by small... Read more ›

Using NASA’s IXPE, astronomers captured an unprecedented view of a white dwarf star actively feeding on material from a companion. The data revealed giant columns of ultra-hot gas shaped by the star’s magnetic field and glowing in intense X-rays. These features are far too small to image directly, but X-ray polarization allowed scientists to map them with surprising precision. The results open new doors for understanding extreme binary star systems. Read more ›

Nearly everything in the universe is made of mysterious dark matter and dark energy, yet we can’t see either of them directly. Scientists are developing detectors so sensitive they can spot particle interactions that might occur once in years or even decades. These experiments aim to uncover what shapes galaxies and fuels cosmic expansion. Cracking this mystery could transform our understanding of the laws of nature. Read more ›

Scientists are uncovering why Brazil may be one of the most important yet underused resources for studying extreme longevity. Its highly diverse population harbors millions of genetic variants missing from standard datasets, including rare changes linked to immune strength and cellular maintenance. Brazilian supercentenarians often remain mentally sharp, survive serious infections, and come from families where multiple members live past 100. Together, they reveal aging not as inevitable decline, but... Read more ›

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still daring to test it. Some theories of quantum gravity suggest light might behave slightly differently at extreme energies. By tracking ultra-powerful gamma rays from distant cosmic sources, researchers searched for tiny timing differences that could reveal new physics. They found none, but their results tighten the limits by a huge... Read more ›

When scientists repeatedly drove a strongly interacting quantum system with laser “kicks,” they expected it to heat up and grow chaotic. Instead, the atoms abruptly stopped absorbing energy and locked into a stable pattern of motion. This strange effect arises from quantum coherence, which prevents the system from thermalizing despite constant forcing. The results overturn classical intuition and offer new insight into how quantum systems can resist disorder. Read more ›

A brief, intense workout may do more than boost fitness—it could help fight cancer. Researchers found that just 10 minutes of hard exercise releases molecules into the bloodstream that switch on DNA repair and shut down cancer growth signals. When these molecules were applied to bowel cancer cells, hundreds of cancer-related genes changed activity. The discovery helps explain how exercise lowers cancer risk and hints at future therapies inspired by... Read more ›
