Scientists warn that the world’s rivers are running out of oxygen
Dissolved oxygen levels are plummeting in nearly 80% of the world's rivers, according to a landmark analysis of more than 21,000 waterways spanning four decades. Climate change is driving the decline, with warmer water holding less oxygen and disrupting the delicate chemistry freshwater ecosystems depend on. The crisis is hitting tropical rivers hardest, posing an outsized threat to biodiversity in regions where aquatic life is already under intense pressure.

Scientists reverse Alzheimer’s in mice with breakthrough nanotechnology
Researchers have developed a nanotechnology treatment that reversed Alzheimer's symptoms in mice by clearing toxic amyloid proteins and repairing the blood-brain barrier. The therapy essentially restored the brain's natural waste-removal system, with treated elderly mice displaying behavior comparable to healthy younger animals. If the results translate to humans, it could represent one of the most significant breakthroughs in Alzheimer's research in decades.

Scientists discover why some cancers survive chemotherapy
Cancer cells may be surviving chemotherapy by exploiting a protein already known for driving tumor growth. Scientists have found that MYC — long notorious for fueling uncontrolled cell proliferation — also rushes to sites of DNA damage and recruits repair machinery, allowing tumors to recover from treatments designed to kill them. The discovery reframes MYC as a dual threat and could open new avenues for therapies that block this repair function, making cancers significantly harder to treat.

AI guardians: Bridging digital innovation and sustainability for cleaner water
AI is now being deployed to monitor wastewater treatment in real time, giving facilities the ability to predict system failures and optimize energy consumption in tandem. Researchers behind the framework describe it as a "twin transition" model — one that pursues digital innovation and environmental sustainability as parallel goals rather than competing priorities. The approach could reshape how utilities manage resources while meeting increasingly stringent environmental standards.
