- newScientists reveal a hidden hormone switch for learning
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.

- newNew evidence shows tirzepatide and semaglutide strongly protect the heart
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.

- newSimple amino acid supplement greatly reduces Alzheimer’s damage
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.

- newA drug already in trials may stop chemotherapy nerve damage
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.

- newThis tiny pill could change how we diagnose gut health
Tiny ingestible spheres filled with engineered bacteria can detect intestinal bleeding by glowing when they encounter heme. Early tests in mice suggest they could become a quick, noninvasive way to monitor gut disease.

- Triple therapy sparks a powerful immune attack on leukemia
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.

- Tiny microneedle patch dramatically improves heart attack recovery
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.

- Scientists grow a tiny human “blood factory” that actually works
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.

- Nearly 47 million Americans live near hidden fossil fuel sites
A nationwide analysis has uncovered how sprawling fossil fuel infrastructure sits surprisingly close to millions of American homes. The research shows that 46.6 million people live within about a mile of wells, refineries, pipelines, storage sites, or transport facilities. Many of these locations release pollutants that may affect nearby communities, yet mid-supply-chain sites have rarely been studied. The findings reveal major gaps in understanding how this hidden network affects health.

- Scientists reawaken exhausted T cells to supercharge cancer immunity
Researchers discovered a way to keep T cells from wearing out during the fight against cancer, and the approach could make immune-based treatments far more powerful. They found that tumors use a particular molecular signal to weaken T cells, and that interrupting this signal helps the cells stay active.

- New research shows hot tubs trigger surprising health benefits saunas don’t
Researchers found that hot tubs raise core body temperature more effectively than traditional or infrared saunas, leading to stronger boosts in blood flow and immune activity. Only hot-water immersion produced measurable changes in inflammatory markers. These effects can persist beyond the session, suggesting a sustained health benefit. For anyone unable or unwilling to exercise, heat therapy may offer a surprisingly effective option.

- Blocking a single protein forces cancer cells to self-destruct
Researchers uncovered a powerful weakness in lung cancer by shutting down a protein that helps tumors survive stress. When this protein, FSP1, was blocked, lung tumors in mice shrank dramatically, with many cancer cells essentially triggering their own self-destruct mode. The work points to a fresh strategy for targeting stubborn lung cancers.

- Simple molecule shows remarkable Alzheimer’s reversal in rats
Scientists have developed a new molecule that breaks down beta-amyloid plaques by binding to excess copper in the brain. The treatment restored memory and reduced inflammation in rats, while also proving non-toxic and able to cross the blood–brain barrier. Because it’s far simpler and potentially cheaper than existing drugs, researchers are now pursuing partnerships to begin human trials.

- Inflammation turns bone marrow into a breeding ground for disease
Researchers discovered that chronic inflammation fundamentally remodels the bone marrow, allowing mutated stem cell clones to quietly gain dominance with age. Reprogrammed stromal cells and interferon-responsive T cells create a self-sustaining inflammatory loop that weakens blood production. Surprisingly, the mutant cells themselves may not be the main instigators.
