Scientists say just 30 minutes of exercise a week could transform your health

You may not need hours at the gym to boost your health after all. Researchers say just 30 minutes of high-intensity exercise per week — broken into tiny bursts of effort that leave you out of breath — can dramatically improve cardiovascular fitness, lower the risk of dozens of diseases, and even help protect the brain as we age. The key isn’t how long you exercise, but how hard you push yourself.

Colon cancer is rising in young adults and doctors don’t fully know why

Colorectal cancer is increasingly showing up in younger adults, with cases now appearing in people as young as their thirties — often with no family history or warning signs. A major Swiss study analyzing nearly 100,000 cases over four decades found that diagnoses in people under 50 have been steadily climbing, even as rates fall among older adults thanks to screening programs. Researchers say younger patients are also more likely to be diagnosed late, after the cancer has already spread.

Scientists discover the Southern Ocean is “sweating” more as climate change intensifies

A remote island between Australia and Antarctica is showing signs of a dramatic climate transformation. Scientists found storms over Macquarie Island now unleash much heavier rainfall than they did decades ago, soaking ecosystems and altering fragile vegetation. The discovery hints that the Southern Ocean — one of Earth’s biggest climate regulators — may be changing faster than expected. Researchers say the ocean could now be cooling itself by “sweating” more moisture into the atmosphere.

New psychedelic-like drugs could treat depression without making you trip

UC Davis researchers created brand-new psychedelic-like compounds by shining UV light on amino acid-based molecules. These compounds activated key serotonin receptors tied to brain plasticity and mental health benefits, but surprisingly did not cause hallucination-like behavior in animal tests. Scientists say the discovery could lead to future treatments for depression, PTSD, and addiction without the intense psychedelic experience.

New drugs could wipe out the “zombie cells” linked to cancer and aging

Researchers found a new way to kill harmful “zombie” cells that linger after chemotherapy and help cancers become more aggressive. These senescent cells survive by relying on a protective protein called GPX4, even while sitting on the edge of a deadly iron-triggered collapse. New drugs remove that protection, causing the cells to self-destruct. In mice, the approach reduced tumor size and boosted survival, hinting at a promising new cancer therapy.
