Colorectal cancer in young people is often diagnosed at an advanced stage, with researchers finding most patients age 21 or younger already had Stage III or IV disease. Because symptoms like rectal bleeding, weight loss, abdominal pain, and bowel changes may be overlooked, resear
A ketogenic diet increased small-intestinal tumors in cancer-prone mice while reducing tumors in the colon, revealing a strikingly different response within neighboring parts of the gut. Researchers traced the increased risk not to ketones, but to the way intestinal stem cells pr
Scientists found that prolonged fasting triggers major changes throughout the body, but many of the most interesting effects only appeared after about three days without food. The results suggest fasting may influence health in ways that go beyond weight loss and could eventually
A UCLA study links faster brain aging to specific gut bacteria and chemical byproducts, with older-looking brains also associated with poorer memory, focus, and mood. The findings suggest that biological signs of brain aging may appear decades before obvious symptoms and could ev
High-risk MDS stem cells appear to have an unexpected “energy addiction,” relying far more heavily than healthy blood-forming cells on a molecule called NAD. Disrupting this energy pathway selectively weakened the cancer-driving cells, revealing a potential new target for treatme
A common mistake during blood pressure checks could make readings appear substantially higher than they really are. Johns Hopkins researchers found that leaving the arm unsupported can raise systolic readings by about 6.5 mmHg, potentially affecting a hypertension diagnosis.
A review of more than 265,000 people found that cannabis use was associated with higher rates of both committing violence and becoming a victim of it. The researchers say the link is significant but does not prove cannabis itself is the cause.
A massive MRI study found that Alzheimer’s disease, mild cognitive impairment, psychiatric disorders, and addiction are associated with distinct patterns of accelerated brain aging. The strongest effects appeared in Alzheimer’s and mild cognitive impairment, while ADHD and autism
People with diabetes reported better quality of life after days when their glucose stayed largely within a healthy range, even when levels fluctuated more than usual. The unexpected finding suggests that pursuing extremely tight glucose control may sometimes come with a hidden li
Scientists resurrected antimicrobial peptides from mammals that lived millions of years ago and found that some were more potent against drug-resistant bacteria than modern human versions. These evolutionary relics could provide new clues for designing treatments as antibiotic re
Scientists discovered rare flavoalkaloids in Cannabis leaves for the first time, along with dozens of other phenolic compounds that had never been reported in the plant. The findings suggest that Cannabis leaves, often discarded as waste, may contain a surprisingly rich source of
A major analysis suggests Phelan-McDermid syndrome, a genetic disorder closely linked to autism, may affect about 1 in 7,300 people and more than 45,000 Americans. Researchers warn that thousands of cases may remain hidden because genetic testing is often not performed, even as t
Scientists discovered that disrupting the chemical messages bacteria use to communicate can push dental plaque toward a healthier microbial balance. The approach could lead to new treatments for gum disease that control harmful bacteria without destroying beneficial species.
Cannabinoids may intensify anxiety by removing a natural brake on specific neurons in the brain’s fear center, particularly during stressful situations. In mice, shutting down those neurons sharply reduced cannabinoid-related anxious behavior.
Colorectal cancer in young people is often diagnosed at an advanced stage, with researchers finding most patients age 21 or younger already had Stage III or IV disease. Because symptoms like rectal bleeding, weight loss, abdominal pain, and bowel changes may be overlooked, resear
Scientists have found a surprising way to regrow damaged knee cartilage by blocking a protein that becomes more abundant with age. In old mice, the treatment restored naturally lost cartilage and also helped prevent osteoarthritis after ACL-like knee injuries, while human cartila
Couples who exercise together report better communication, healthier conflict resolution, and lower marital stress than those who work out alone. Even something as simple as taking a walk together may create valuable opportunities to talk, listen, and feel more connected.
New mothers paired with patient navigators were much more likely to receive postpartum care, depression screening, preventive testing, and ongoing primary care. By helping with barriers such as transportation, childcare, scheduling, and confusing medical information, navigators m
In a small study, sleeping near the scent of Hinoki root essential oil was linked to fewer nighttime awakenings, better morning alertness, and brain-wave changes associated with smoother sleep onset. The findings suggest an overlooked forestry byproduct could someday become a nat
A ketogenic diet increased small-intestinal tumors in cancer-prone mice while reducing tumors in the colon, revealing a strikingly different response within neighboring parts of the gut. Researchers traced the increased risk not to ketones, but to the way intestinal stem cells pr

A new nanoparticle therapy reduced lung tumors in mice while also targeting cachexia, the severe muscle wasting that can accompany cancer. By delivering follistatin mRNA directly to tumors, the approach could eventually offer a way to fight both the disease and one of its most da
Scientists have discovered a human gene with a remarkable double life: it appears to play an important role in brain cells while still retaining the ability to jump around the genome. Called BC200, the gene evolved millions of years ago from a mobile piece of DNA known as a trans
Cancer immunotherapy can lose its punch when tumor-fighting T cells become exhausted, but researchers may have found a way to keep them going longer. Scientists at Memorial Sloan Kettering Cancer Center identified a signaling molecule called MEK that can push T cells to burn thro
