This discovery could let bones benefit from exercise without moving

Researchers have discovered a biological switch that explains why movement keeps bones strong. The protein senses physical activity and pushes bone marrow stem cells to build bone instead of storing fat, slowing age-related bone loss. By targeting this “exercise sensor,” scientists believe they could create drugs that mimic exercise at the molecular level. The approach could protect fragile bones in people who are unable to stay active.

Scientists just cracked the hidden rules of cancer evolution

Cancer doesn’t evolve by pure chaos. Scientists have developed a powerful new method that reveals the hidden rules guiding how cancer cells gain and lose whole chromosomes—massive genetic shifts that help tumors grow, adapt, and survive treatment. By tracking thousands of individual cells over time, the approach shows which chromosome combinations give cancer an edge and why some tumors become especially resilient.

Scientists exposed how cancer hides in plain sight

Pancreatic cancer may evade the immune system using a clever molecular trick. Researchers found that the cancer-driving protein MYC also suppresses immune alarm signals, allowing tumors to grow unnoticed. When this immune-shielding ability was disabled in animal models, tumors rapidly collapsed. The findings point to a new way to expose cancer to the body’s own defenses without harming healthy cells.

This new antibody may stop one of the deadliest breast cancers

Researchers have identified a promising new weapon against triple-negative breast cancer, one of the most aggressive forms of the disease. An experimental antibody targets a protein that fuels tumor growth and shuts down immune defenses, effectively turning the immune system back on. In early tests, the treatment slowed tumor growth, reduced lung metastases, and destroyed chemotherapy-resistant cancer cells.

A common painkiller may be quietly changing cancer risk

Ibuprofen may be doing more than easing aches and pains—it could also help reduce the risk of some cancers. Studies have linked regular use to lower rates of endometrial and bowel cancer, likely because the drug dampens inflammation that fuels tumor growth. Researchers have even found it can interfere with genes cancer cells rely on to survive. Still, experts warn that long-term use carries risks and shouldn’t replace proven prevention strategies.

How cancer disrupts the brain and triggers anxiety and insomnia

Scientists have discovered that breast cancer can quietly throw the brain’s internal clock off balance—almost immediately after cancer begins. In mice, tumors flattened the natural daily rhythm of stress hormones, disrupting the brain-body feedback loop that regulates stress, sleep, and immunity. Remarkably, when researchers restored the correct day-night rhythm in specific brain neurons, stress hormone cycles snapped back into place, immune cells flooded the tumors, and the cancers shrank—without using any anti-cancer drugs.

Vitamin A may be helping cancer hide from the immune system

A vitamin A byproduct has been found to quietly disarm the immune system, allowing tumors to evade attack and weakening cancer vaccines. Scientists have now developed a drug that shuts down this pathway, dramatically boosting immune responses and slowing cancer growth in preclinical studies.

Northwestern Medicine’s new antibody wakes the immune system against pancreatic cancer

Pancreatic cancer uses a sugar-coated disguise to evade the immune system, helping explain why it’s so hard to treat. Northwestern scientists discovered this hidden mechanism and created an antibody that strips away the tumor’s protective signal. In animal tests, immune cells sprang back into action and tumors grew much more slowly. The team is now refining the therapy for future human trials.

Scientists discover how the uterus knows when to push during childbirth

Childbirth depends not just on hormones, but on the uterus’s ability to sense physical force. Scientists found that pressure and stretch sensors in uterine muscles and surrounding nerves work together to trigger coordinated contractions. When these sensors are disrupted, contractions weaken and delivery slows. The discovery helps explain stalled labor—and could one day lead to better ways to manage childbirth.
