Paleontologists make 'one in a million' discovery of soft tissue preserved in 450-million-year-old fossil
Researchers have uncovered preserved soft tissue in a 450-million-year-old crinoid fossil, predating land-dwelling animals and plants by tens of millions of years. The extraordinary find offers a direct window into the biology of these ancient reef-dwellers, whose fossilized remains are typically limited to hard skeletal structures. Scientists say the discovery could reshape understanding of how complex life first organized itself in Earth's primordial oceans.

Scientists solve a 30-year rye pollen mystery that could transform cancer research
Scientists have cracked the molecular structure of two rye pollen compounds that first showed tumor-fighting potential nearly three decades ago, resolving a puzzle that had stalled progress in the field. The breakthrough gives researchers the precise 3D blueprint needed to study how these natural molecules interact with the immune system. With the structural mystery solved, scientists can now investigate which specific components drive their anti-cancer effects and potentially engineer new therapeutics based on them.

Scientists may have finally found how Alzheimer's kills brain cells
Researchers have pinpointed a previously unknown pathway through which Alzheimer's disease destroys brain cells, a discovery that could fundamentally reshape how the condition is treated. The mechanism also appears to drive frontotemporal dementia, suggesting broader implications for neurodegenerative disease. By targeting this process before cell death occurs, scientists believe new therapies could slow or even halt the progression of conditions that have long resisted effective treatment.

Nanobubbles cleaned up the Lincoln reflecting pool: Here's how they could be used on dying seas and lakes
Ozone nanobubble technology successfully cleared a stubborn algae bloom at the Lincoln Memorial Reflecting Pool ahead of America's 250th anniversary celebrations, after a $1.7 million system injected microscopic bubbles into the water. The technology works by dissolving ozone into near-invisible bubbles that penetrate water more effectively than conventional treatment methods, eliminating algae without harsh chemicals. Proponents argue the approach could scale to address dying lakes and seas worldwide, offering a promising tool in the fight against eutrophication.

The world's oceans are the hottest on record for June—and El Niño is set to turn up the heat even more
Global ocean temperatures hit an all-time high for June, surpassing records set during the intense 2023–24 El Niño cycle. The timing is particularly alarming, as forecasters warn that a developing El Niño could drive temperatures even higher in the months ahead. For marine ecosystems and weather systems already under strain, the compounding heat signals a deepening climate crisis.
