This week in Break It Down, we explore why Uranus might contain more methane than we thought, just what is happening to bacteria on the ISS, quite how long animals have been making their own light for, why carvings on a bear bone are culturally important, giant megaraptor footprints in China, and whether anything spooky might happen if you dare to enter the Pharaoh's tomb.
Sit back, relax, and let's Break It Down...

This week in Break It Down, a new species of tiny titanosaur is compared to a cow, a 47-million-year-old snake becomes the largest ever, an RNA breakthrough brings us closer to "universal vaccines", a heart flies 7,000 kilometers to its recipient, we question Stonehenge's relationship to the Moon, and why the philosophy of science matters in the modern day.

This week in Break It Down, a rainbow-like glory is detected beyond our Solar System, a sand-slab stingray may be the oldest animal art, ancient etchings in Peru may depict psychedelic music, scientists complete the world’s largest digital camera, and a toad with heart-shaped pupils. Plus, how far can a bird fly without flapping? Turns out, pretty damn far.

This week in Break It Down, why the solar eclipse can be fatal, Barbie pigs 5,000 meters below the sea, world-first cooperative mimicry in two spiders pretending to be a flower, the first image of magnetic fields around black hole Sagittarius A*, why climate change might be about to change the time, and are men really more likely to be psychopaths than women? The science appears to suggest otherwise.

This week in Break It Down, a once-in-a-lifetime opportunity to see a nova, astroforensic science, why everybody thinks male mammals are so big, the world’s oldest body piercings, 70 years in an iron lung, and the strange things animals do during a total solar eclipse. We’re looking at you, Galápagos tortoises.

This week in Break It Down, we talk de-extincting the mammoth, the world’s oldest fossil forest, elephant burials, hypervaccination (and by hyper, we mean 217 COVID vaccinations in 29 months), a small Pacific nation that spans all four hemispheres, and a contentious question on geologists’ lips: are we in the Anthropocene?
