Several popular sugar substitutes may not be as harmless as they seem. Adults who consumed the most artificial sweeteners showed substantially faster declines in memory and thinking, especially if they were under 60 or had diabetes. The highest intake was linked to cognitive aging roughly 1.6 years faster than the lowest intake. Researchers stressed that more studies are needed before concluding that sweeteners are the cause.

Scientists at Baylor College of Medicine may have uncovered a promising new way to combat Alzheimer’s and Parkinson’s disease. Instead of trying to stop Tau and alpha-synuclein proteins from gathering into tiny droplets inside brain cells, the researchers found that tubulin—the protein that builds the cell’s internal transport network—can redirect these proteins away from forming toxic clumps and toward healthy, productive work.

A long-term Yale study is challenging one of the biggest myths about aging. Nearly half of adults over 65 improved physically, mentally, or both over time, despite the common belief that aging means constant decline. Researchers found that people with more positive attitudes about getting older were significantly more likely to show these gains. Read more ›

Despite centuries of study, scientists are still finding new details and even overlooked structures within the human body. As researchers explore anatomical differences between individuals, it’s becoming clear that the body is far more complex—and less fully understood—than textbooks suggest. Read more ›

As newborn neurons make their way through the developing brain, they must squeeze through incredibly tight spaces to reach their final destinations. Researchers discovered that this physical journey routinely causes some of the most severe forms of DNA damage—double-strand breaks—yet the young brain has evolved an impressive ability to repair the damage almost immediately.

Researchers have concluded that nicotine vapes are likely to cause lung and oral cancers, based on evidence ranging from human biomarkers to animal and laboratory studies. The findings challenge the idea that vaping is a harmless alternative to smoking and suggest health risks may be emerging much sooner than many expected. Read more ›

Researchers found that twisting layered sheets of hexagonal boron nitride can dramatically change the light produced by quantum emitters embedded within the material. The technique offers an unexpected new level of control over components that could power future quantum computers, communications systems, and sensors. Read more ›

Compounds responsible for the aroma of cannabis and many other plants may offer a surprising new way to relieve chronic pain. Researchers found that several cannabis-derived terpenes significantly reduced pain in mouse models of fibromyalgia and post-surgical pain, with one terpene, geraniol, showing especially strong effects. Unlike THC, these compounds are not associated with psychoactive effects, making them a potentially attractive alternative for pain treatment. Read more ›

The global cobalt supply chain is more interconnected—and more vulnerable—than previously thought, with disruptions capable of triggering far-reaching cascades across multiple countries and industries. Researchers warn that protecting battery supply chains will require system-wide coordination because critical bottlenecks can turn local shocks into global problems. Read more ›

A surprising new study suggests the earliest primates didn't originate in tropical forests but in cold, dry parts of North America. Some may have even survived seasonal Arctic conditions by slowing their metabolism or hibernating. Researchers found that dramatic climate shifts, rather than warmth, played a major role in driving primate evolution and expansion. The discovery reshapes our understanding of how our own lineage began. Read more ›

Scientists have discovered that a gene normally considered a DNA-protecting "good guy" can become dangerous when cells make too much of it. The gene, EXO1, acts like molecular scissors that help repair DNA, but when overproduced it starts cutting DNA it shouldn't, creating damage linked to cancer. Read more ›

The obesity treatment landscape is changing fast, with GLP-1 drugs opening the door to more effective care than ever before. Experts now envision a future where medications, minimally invasive procedures, surgery, and precision medicine work together to deliver better long-term results. Read more ›

Scientists found that thawing permafrost can trigger increased rock weathering, a natural process that absorbs CO2 from the atmosphere. In some regions, this carbon uptake was strong enough to fully offset — or even surpass — river greenhouse gas emissions. Read more ›

Animals from different species often rely on surprisingly sophisticated communication to work together, whether finding food, cleaning parasites, or gaining protection. New research suggests these interspecies “conversations” are flexible, evolved, and far more important to life in nature than scientists once realized. Read more ›

Eating five servings of fruits and vegetables may not be enough if you're missing foods rich in flavanols, a group of compounds linked to better heart health. Researchers found that choices like blackberries, plums, apples, broad beans, cherries, and green tea can dramatically increase flavanol intake. Read more ›

A distant galaxy nicknamed Shadow Blaster may have revealed a surprising source of cosmic neutrinos: extreme star formation instead of a supermassive black hole. The discovery suggests that hidden, dust-filled starburst galaxies could account for a significant fraction of the Universe’s high-energy neutrinos. Read more ›

Researchers developed a Wordle-solving strategy that succeeds 99% of the time by focusing on information gain rather than likely answers. The method uses Shannon entropy to identify guesses that reveal the most about the hidden word. Each guess is designed to slash uncertainty and narrow the possibilities faster. The result significantly outperformed more traditional Wordle tactics. Read more ›

A newly identified molecule called OLE helped restore the brain’s immune cells to a more protective state in Alzheimer’s models. The treatment reduced toxic plaque buildup and improved memory, raising hopes for a new therapeutic approach. Read more ›

Scientists have uncovered a surprising connection between quantum gravity and an exotic quantum state of matter that could explain why the universe isn’t expanding wildly fast. The study suggests that the very shape of space-time may protect the cosmological constant from disruptive quantum effects. Read more ›

A new biomaterial made from jackfruit latex, pomegranate peel, and simvastatin could transform the treatment of severe gum disease. Early tests suggest it not only combats infection and inflammation but may also help rebuild lost bone and tissue around teeth. Read more ›

Researchers have created a new way to reconstruct the evolutionary history of complex plant genomes by analyzing genetic traces left by transposable elements. The technique revealed that modern strawberries were assembled through multiple ancient genome-merging events, shedding new light on how major crop species evolved. Read more ›
