Science
Physics, climate, planetary science, and the research that shapes how we understand the universe and our place in it.


Only one spacecraft has ever visited Uranus or Neptune: Voyager 2, which flew past Uranus in 1986 and Neptune in 1989. Nearly four decades later, no mission has returned, leaving many of the biggest questions those flybys raised — about the planets’ interiors, strange magnetic fields, rings, and moons — still unresolved.

Scientists took one of the naked mole rat’s longevity tricks — a gene that helps it produce unusually protective hyaluronan — and put it into mice. The result: the mice lived longer, had less inflammation, and were more resistant to tumours.

A McMaster University AI model called SyntheMol-RL designed a new antibiotic candidate by searching a chemical space of 46 billion possible compounds — a scale far beyond physical lab screens, which usually test hundreds of thousands to a few million molecules.

We tend to think quantum tunnelling is a subatomic curiosity, but in 1984 and 1985 physicists at UC Berkeley showed that a superconducting electrical circuit big enough to hold in your hand could tunnel from one state to another — a discovery that won the 2025 Nobel Prize in Physics.

In 2018, low Earth orbit still had months of margin: if satellites stopped dodging one another, researchers estimate it could take 164 days before a catastrophic collision. By 2025, after the rise of megaconstellations, that margin had collapsed to just 5.5 days.

A bowhead whale can live for more than 200 years, yet it appears unusually resistant to cancer — and its genome carries genetic changes that may help explain why. Researchers have found signs of enhanced DNA repair in bowhead cells, turning one of the Arctic’s oldest mammals into a serious model for understanding aging itself.

In 1977, Ann Druyan recorded an hour of her brainwaves and heartbeat just two days after she and Carl Sagan agreed to marry, and NASA pressed that compressed minute onto Voyager's Golden Record as a private love letter now more than 25 billion kilometres from Earth

For decades, marine biologists have followed a lone whale in the North Pacific known as "52 Blue" because it sings at a frequency of 52 hertz — far higher than the great baleen whales it swims among — meaning that for its entire life it has been calling out into the dark in a voice that, as far as anyone knows, no other whale has ever answered

Nearly all of the internet's international data — the messages, calls, and searches that cross continents — travels through fibre-optic cables laid on a seafloor that has never been fully surveyed, running over terrain no human eye has seen

Scientists long thought life in the deepest ocean trenches depended mostly on scraps of sunlight-fed life drifting down from above — but at 9,500 metres beneath the Pacific, researchers found whole communities of tubeworms and clams powered instead by methane and hydrogen sulfide seeping from cracks in the seafloor.
