A major study suggests that when you eat could play a key role in staying lean. People who fast longer overnight and start their day with an early breakfast were more likely to have a lower BMI years later. Scientists think this is because eating earlier aligns better with the body’s internal clock. But skipping breakfast as part of intermittent fasting didn’t offer the same advantage—and may even be tied to unhealthy habits.

Scientists searching for air pollution clues stumbled onto something unexpected: toxic MCCPs drifting through the air for the first time in the Western Hemisphere. The likely source—fertilizer made from sewage sludge—points to a hidden route for contamination.

Scientists have achieved the unthinkable by stabilizing a highly reactive molecule in water, confirming a decades-old theory about vitamin B1’s role in the body. The breakthrough not only solves a scientific mystery but could revolutionize greener chemical manufacturing.

Losing your sense of smell might signal Alzheimer’s far earlier than expected. Scientists found that immune cells in the brain actively destroy smell-related nerve fibers after detecting abnormal signals on their surfaces. This damage begins in early stages of the disease, well before cognitive decline. The discovery could help identify at-risk patients sooner and improve treatment timing.

Mars may be hostile, but it might not be entirely unlivable. In lab experiments, yeast cells survived simulated Martian shock waves and toxic perchlorate salts—two major environmental threats on the Red Planet. Their secret weapon was forming protective molecular clusters that shield critical cellular functions under stress. Without these defenses, survival plummeted, pointing to a potential universal strategy life could use beyond Earth.
