- newGiving people cash didn’t cause more injuries or deaths
As cash transfer programs expand across the United States, critics often warn that giving people money could spark reckless behavior, leading to injuries or even deaths. But a sweeping 11-year analysis of Alaska’s long-running Permanent Fund Dividend program tells a different story. Researchers examined statewide hospital records and death data and found no increase in traumatic injuries or unnatural deaths after annual payments were distributed.

- newThis new blood test could detect cancer before it shows up on scans
A new light-based sensor can spot incredibly tiny amounts of cancer biomarkers in blood, raising the possibility of earlier and simpler cancer detection. The technology merges DNA nanotechnology, CRISPR, and quantum dots to generate a clear signal from just a few molecules. In lung cancer tests, it worked even in real patient serum samples. Researchers hope it could eventually power portable blood tests for cancer and other diseases.

- newOne in three people carry this brain parasite but the body has a kill switch
A parasite that may already be hiding in your brain has a shocking survival trick: it can infect the very immune cells sent to destroy it. Yet most people never get sick, and new research from UVA Health reveals why. Scientists discovered that when Toxoplasma gondii invades CD8+ T cells — key defenders of the immune system — those cells can trigger a self-destruct mechanism powered by an enzyme called caspase-8. By sacrificing themselves, the infected cells also wipe out the parasite inside…

- newLab grown human spinal cord heals after injury in major breakthrough
Researchers have built a realistic human mini spinal cord in the lab and used it to simulate traumatic injury. The model reproduced key damage seen in real spinal cord injuries, including inflammation and scar formation. After treatment with fast moving “dancing molecules,” nerve fibers began growing again and scar tissue shrank. The results suggest the therapy could eventually help repair spinal cord damage.

- newBrain inflammation may be driving compulsive behavior
For years, compulsive behaviors have been viewed as bad habits stuck on autopilot. But new research in rats found the opposite: inflammation in a key decision-making brain region actually made behavior more deliberate, not more automatic. The change was linked to astrocytes, brain support cells that multiplied and disrupted nearby circuits. The discovery hints that some compulsive behaviors may arise from excessive, misdirected control rather than a loss of it.

- Exercise may be one of the most powerful treatments for depression and anxiety
A sweeping review of global research suggests that exercise—especially aerobic activities like running, swimming, and dancing—can be one of the most powerful ways to ease depression and anxiety. Across tens of thousands of people aged 10 to 90, exercise consistently reduced symptoms, often matching or even outperforming medication and talk therapy.

- Scientists discover the enzyme that lets cancer rapidly rewire its DNA
Researchers have uncovered the enzyme behind chromothripsis, a chaotic chromosome-shattering event seen in about one in four cancers. The enzyme, N4BP2, breaks apart DNA trapped in tiny cellular structures, unleashing a burst of genetic changes that can help tumors rapidly adapt and resist therapy. Blocking the enzyme dramatically reduced this genomic destruction in cancer cells.

- This planet friendly diet could cut your risk of early death by 23%
A major new study suggests that eating the Nordic way could help you live significantly longer—while also helping the planet. Researchers from Aarhus University found that people who closely followed the 2023 Nordic dietary guidelines had a 23% lower risk of death compared to those who didn’t.

- Why some kids struggle with math even when they try hard
A new Stanford study suggests math struggles may be about more than numbers. Children who had difficulty with math were less likely to adjust their thinking after making mistakes during number comparison tasks. Brain imaging showed weaker activity in regions that help monitor errors and guide behavioral changes. These brain patterns could predict which children were more likely to struggle.

- Large study finds no link between mRNA COVID vaccine in pregnancy and autism
Researchers tracked more than 400 toddlers to see whether mRNA COVID-19 vaccination during or just before pregnancy was linked to autism or developmental delays. After detailed assessments of speech, motor skills, behavior, and social development, they found no meaningful differences between vaccinated and unvaccinated groups. Experts say the results provide strong reassurance about vaccine safety in pregnancy.

- AI uncovers the hidden genetic control centers driving Alzheimer’s
Scientists have created the most detailed maps yet of how genes control one another inside the brains of people with Alzheimer’s disease. Using a powerful new AI-based system called SIGNET, the team uncovered cause-and-effect relationships between genes across six major brain cell types, revealing which genes are truly driving harmful changes. The most dramatic disruptions were found in excitatory neurons, where thousands of genetic interactions appear to be extensively rewired as the disease…

- Stop eating 3 hours before bed to improve heart health
A simple shift in your evening routine may give your heart a measurable boost. In a new study, adults who stopped eating and dimmed the lights three hours before bed and extended their overnight fast by about two hours saw improvements in blood pressure, heart rate, and blood-sugar control — without cutting calories.

- Scientists find nerves actively fuel pancreatic cancer
Scientists have uncovered a hidden partnership between pancreatic cancer and the nervous system. Support cells in the pancreas lure nerve fibers, which then release signals that accelerate early cancer growth. This creates a self-sustaining loop that helps tumors take hold. Blocking the nerve activity significantly reduced tumor growth in experiments, suggesting a new treatment strategy.

- Scientists found a way to plant ideas in dreams to boost creativity
Sleeping on a problem might be more powerful than we ever imagined. Neuroscientists at Northwestern University have shown that dreams can actually be nudged in specific directions — and those dream tweaks may boost creativity. By playing subtle sound cues during REM sleep, researchers prompted people to dream about unsolved brain teasers they had struggled with earlier. An astonishing 75% of participants dreamed about the cued puzzles, and those puzzles were solved far more often the next day.

- Psychedelics may work by shutting down reality and unlocking memory
Psychedelics can quiet the brain’s visual input system, pushing it to replace missing details with vivid fragments from memory. Scientists found that slow, rhythmic brain waves help shift perception away from the outside world and toward internal recall — almost like dreaming while awake. By imaging glowing brain cells in mice, researchers watched this process unfold in real time.
