Mutations of DNA do not occur as randomly as previously assumed, according to new research from Max Planck Institute for Biology Tübingen in Germany and University of California Davis in the US. The findings have the potential to dramatically change our view of evolution. The insights have far-reaching implications, from better knowledge of crop domestication to predictions of the mutational landscape in cancers.

Anyone who saw the movie The Core all the way back in 2003 probably already knows everything about the inside of the planet already.

Researchers at ETH Zurich have demonstrated in the lab how well a mineral common at the boundary between the Earth’s core and mantle conducts heat. This leads them to suspect that the Earth’s heat may dissipate sooner than previously thought.

The evolution of the planet Earth can be described as the history of cooling over the past 4.5 billion years. The surface of the Earth was covered with a deep ocean of magma.

Mordor on Earth? Magma from the depths of hell is seeping through a mysterious crack

Somewhere in central Panama, there is an almost unearthly phenomenon of an opening going deep into the mantle.

Earth isn’t going to open up its gaping maw, dragonlike, and swallow us all into the inferno anytime soon, but it is exhaling hot breath somewhere under Panama.

Melting Arctic ice will have catastrophic effects on the world, experts say. Here’s how.

The Arctic is the “frontline” for climate change, scientists said.

If there is any doubt about climate change, look no further than the coldest regions of the planet for proof that the planet is warming at unprecedented rates, experts say.

Cosmology’s biggest conundrum is official, and no one knows how the Universe has expanded

Cosmology’s biggest conundrum is official, and no one knows how the Universe has expanded

After more than two decades of precision measurements, we’ve now reached the “gold standard” for how the pieces don’t fit.

  • There are two fundamentally different ways of measuring the expanding Universe: a “distance ladder” and an “early relic” method.
  • The early relic method prefers an expansion rate of ~67 km/s/Mpc, while the distance ladder prefers a value of ~73 km/s/Mpc — a discrepancy of 9%.
  • Owing to Herculean efforts by the distance ladder teams, their uncertainties are now so low that there is a 5-sigma discrepancy between the values. If the discrepancy isn’t due to an error, there may be a new discovery.

What Is Math?

Young man looks at math symbols on a chalk board and wonders

A teenager asked that age-old question on TikTok, creating a viral backlash, and then, a thoughtful scientific debate.

It all started with an innocuous TikTok video posted by a high school student named Gracie Cunningham. Applying make-up while speaking into the camera, the teenager questioned whether math is “real.” She added: “I know it’s real, because we all learn it in school… but who came up with this concept?” Pythagoras, she muses, “didn’t even have plumbing—and he was like, ‘Let me worry about y = mx + b’”—referring to the equation describing a straight line on a two-dimensional plane. She wondered where it all came from. “I get addition,” she said, “but how would you come up with the concept of algebra? What would you need it for?”

Think Climate Change Is Messy? Wait Until Geoengineering

Someone’s bound to hack the atmosphere to cool the planet. So we urgently need more research on the consequences, says climate scientist Kate Ricke.

Here’s the thing about the stratosphere, the region between six and 31 miles up in the sky: If you really wanted to, you could turn it pink. Or green. Or what have you. If you sprayed some colorant up there, stratospheric winds would blow the material until it wrapped around the globe. After a year or two, it would fade, and the sky would go back to being blue. Neat little prank.

Does the expansion of the Universe break the speed of light?

Just 13.8 billion years after the hot Big Bang, we can see 46.1 billion light-years away in all directions. Doesn’t that violate…something?

  • The cardinal rule of relativity is that there’s a speed limit to the Universe, the speed of light, that nothing can break.
  • And yet, when we look at the most distant of objects, their light has been traveling for no more than 13.8 billion years, but appears much farther away.
  • Here’s how that doesn’t break the speed of light; it only breaks our outdated, intuitive notions of how reality ought to behave.
