Could Spinosaurus swim? The fierce dinosaur ignites debate
Researchers are still divided about whether Spinosaurus was a swimmer or a wader. What’s clear is that confirming the first swimming dinosaur would be a game-changer.

Climate change is driving the extreme heat baking France’s Olympics
In this week’s Extreme Climate Update, we look at record-breaking temps around the world and explain what the heat index is.

Beneficial bacteria help these marine worms survive extreme cold
Three species of marine worms living in Antarctic waters have beneficial relationships with bacteria that produce antifreeze proteins.

A rapid shift in ocean currents could imperil the world’s largest ice shelf
Roughly the size of Spain, the Ross Ice Shelf stabilizes major glaciers along Antarctica’s coast — and is at risk of retreating, a new study finds.

Warm water is sneaking underneath the Thwaites Glacier — and rapidly melting it
The salty water, just 3.6 degrees Celsius above the ice’s melting point, is undermining the foundation of the Antarctic glacier.

We may finally know the source of mysterious high-energy neutrinos
Regions around supermassive black holes in active galaxies could produce a lot of these mysterious particles.

Something weird is happening to Earth’s inner core
A new study claims to confirm that the inner core is now rotating more slowly than it was over a decade ago, but some researchers remain skeptical.

An asteroid may have exploded over Antarctica about 2.5 million years ago
Tiny spherules of rock found in Antarctic ice may point to the oldest known “airburst,” or midair disintegration of an incoming asteroid.

Climate change is changing how we keep time
Polar ice sheets are melting faster, slowing Earth’s spin. That is changing how we synchronize our clocks to tell time.

Three reasons why the ocean’s record-breaking hot streak is devastating
Ocean warming enhances hurricane activity, bleaches coral reefs and melts Antarctic sea ice. That warming has been off the charts for the past year.

3 Antarctic glaciers show rapidly accelerated ice loss from ocean warming
Destabilized by ocean waves and vanishing sea ice, Antarctica’s Hektoria glacier lost 25 kilometers of ice in 16 months — a possible hint of what’s to come.

Speed bumps under Thwaites Glacier could help slow its flow to the sea
A seismic survey of Thwaites’ icy underbelly shows the Antarctica glacier may be snagging on tall rises in land. That could help slow global sea level rise.
