Thomasina and Patrick Tobin died in a hot tub in Spain, and a new theory says physical exhaustion — not drowning or foul play — may explain how.

A JAMA Pediatrics study tracked pesticide metabolites in pregnant women's urine — and its findings challenge a popular theory linking environmental toxins to autism.

A new neuroscience study found warm quantum states in the brain — the exact phenomenon Penrose and Hameroff said would prove consciousness isn't purely classical computation.

A disaster expert says it wasn't a glacial lake burst but a falling wall of ice and rock that triggered Nepal's devastating flash floods — and the difference matters for future warnings.

Nepal's disaster chief says the glacial lake outburst theory for the deadly Nepal-Tibet floods may be wrong — so what actually unleashed the water?

New video footage catches humpback whales eating during their supposed starvation migration — challenging decades of "feast or famine" science.

Lamine Yamal's dribbling numbers have dipped — and some fans think a growth spurt, not a slump, is quietly rewiring his body mid-season.

Nepal's catastrophic flood was blamed on an earthquake, a glacial lake burst, and other causes — and the newest theory may be the most alarming of all.

163 bodies recovered from Nepal's floods, and investigators are now probing whether a glacier collapse or glacial lake outburst triggered the disaster.

A 4.4-magnitude quake, a glacier collapse, and a bursting glacial lake are all competing to explain Nepal's devastating flash floods — and the answer changes who's to blame.

A deadly flood swept from Tibet into Nepal's Rasuwa district — and now investigators are debating whether a glacial burst, dam breach, or cloudbursts triggered it.

A Washington University biologist thinks the brain's own tuning trick could make quantum sensors dramatically more sensitive — borrowing neuroscience to push physics.

Elephants in Kenya's Amboseli Park are dying with paralysis-like symptoms, and experts can't agree on what's killing them.

A federal grant to a Wuhan lab sits at the heart of claims that Fauci funded the research that caused COVID-19 — but what does the actual paperwork show?

A fan theory pins Yellowjackets' wilderness horror on cinnabar mercury poisoning — erethism mimicking madness, paranoia, and hallucination from the inside out.

A 97-generation experiment just challenged what scientists thought they knew about exercise and aging — raising the question of whether the old theory ever held up.

Over 43 healthcare workers have died in DRC's Ebola outbreak, yet many locals believe the disease is a deliberate plot — and that distrust is helping the virus spread faster and wider.

A new surgery treats Alzheimer's as a backed-up brain drain — but McGill researchers say we should be skeptical of the plumbing theory.

A giant rocky exoplanet so dense it shouldn't exist is forcing astronomers to rethink how planets form in the first place.

A 170-million-year-old rocky "mega-Earth" is so dense and large that it shouldn't exist — and astronomers say it breaks the rules of how planets form.
