Not that I would want to live on Mars, but I hear the aeolian geology is unparalleled.

Relics of an ancient sandstorm on Mars point to Earth-like winds Curiosity rover finds what may be the first direct evidence that Mars once had a thick atmosphere

The martian atmosphere is currently 200 times thinner than that of Earth. A 3 billion-year-old sandstorm recorded in the rocks could be the first direct evidence that wasn't always so. My latest for @science.org.🧪⚒️ 🚀🪐

Human populations evolved in similar ways after we began farming An analysis of ancient and modern DNA suggests the extent of convergent evolution in different peoples around the world is even greater than we thought

To me, this shows the how genetic connections 🧬 between peoples can go beyond our shared ancestry. We also have similar or even identical genetic changes because of our shared lifestyles - that is, separate groups of modern humans evolved in similar ways 🧪

What Crystals Older Than the Sun Reveal About the Start of the Solar System | Quanta Magazine Microscopic crystals extracted from meteorites could help settle a debate about the birth of our patch of the Milky Way.

How was our patch of the Milky Way born? Microscopic grains older than the sun are providing clues. @jamesdinneen.bsky.social reports: www.quantamagazine.org/what-crystal...

What Crystals Older Than the Sun Reveal About the Start of the Solar System | Quanta Magazine Microscopic crystals extracted from meteorites could help settle a debate about the birth of our patch of the Milky Way.

If in need of something distant from current events, I wrote for @quantamagazine.bsky.social about meteorites that contain crystals older than the sun. The oldest date back to ~7 billion years, offering a physical measure of stars more than halfway back to the beginning of the universe itself.

Nearing a decade @science.org, this is a point I should stress more. It's only $25/year to support one of the largest science-focused newsrooms in the world. Independent and nonprofit.

Tectonism rather than “snowball Earth” glaciation is responsible for the Great Unconformity | PNAS The Great Unconformity (GUn)—a widely recognized discontinuity and associated gap in the rock record between Precambrian and Cambrian rocks—represe...

Ancient rocks point to an early start for the Great Unconformity—the biggest gap in Earth’s rock record Two-billion-year-old rocks in China suggest mountain building from Earth’s first supercontinent led to a planetwide burst of erosion

A billion years of missing time continues to confound geologists. For @science.org, I covered a new find in northern China that complicates debates on the source of the Great Unconformity:🧪⚒️

How earthquake scientists helped stop nuclear weapons testing Seismologists played a key role in establishing bans on underground nuclear blasts — those bans may be starting to break down

NASA greenlights two earth science missions, to researchers’ relief Orbiting satellites will monitor changes in the stratosphere and on the planet’s surface

Researchers "overjoyed" #NASA is going to move forward with two new $355 million Earth science satellites. One watching stratosphere, one watching ice/forests.🧪 My latest for @science.org:

Mysterious difference between Hawaiian volcanoes may reflect divide deep within Earth Hot mantle plume could be split in two, might eventually produce separate island chains

My latest for @science.org: the plume of hot rock beneath Hawaii may have split in two deep in the mantle. Tens of millions of years from now this could lead to parallel island tracks above the hotspot.🌋

YES. Good news from South America.

Ancient tectonic plates are oozing along Earth’s core Thousands of earthquakes yield best picture yet of core-mantle boundary, shedding light on deep flows of viscous rock

Seismologists use 5000+ earthquakes to detect sunken slabs of ancient tectonic plates flowing along the edge of Earth's core. My latest from #AGU2025 for @science.org🧪:

This startup is about to conduct the biggest real-world test of aluminum as a zero-carbon fuel We got a sneak peek inside Found Energy’s lab, just as it gears up to supply heat and hydrogen to its first customer.

Can fuel made from aluminum scraps supply the clean heat industry needs? For @technologyreview.com, I got a sneak peak of Found Energy's largest aluminum-water reactor to date.

Exclusive: Climate scientists expect attempts to dim the sun by 2100 An exclusive New Scientist survey of leading scientists reveals widespread concern that schemes to tweak Earth’s atmosphere could launch within decades in a risky bid to cool the planet

Here is our exclusive survey asking leading climate scientists to give their views on solar geoengineering:

*66% believe we will see it attempted this century
*52% say it will probably be done by a "rogue actor"
*81% want an international treaty to manage risk

Exclusive: Climate scientists expect attempts to dim the sun by 2100 An exclusive New Scientist survey of leading scientists reveals widespread concern that schemes to tweak Earth’s atmosphere could launch within decades in a risky bid to cool the planet

What do climate scientists really think about solar geoengineering?

For @newscientist.com, @tinymaddie.bsky.social and I surveyed 120 IPCC authors about their attitudes towards solar geoengineering given the world's failure to slash emissions on time. The results were surprising:

Climate scientists believe humans will launch risky schemes to block radiation from the sun in a desperate bid to cool global temperatures before the end of the century - read more in our @newscientist.com excl from myself & @jamesdinneen.bsky.social www.newscientist.com/article/2498...

One of Earth’s most vital carbon sinks is faltering. Can we save it? For decades, forest, grasslands and other land ecosystems have collectively absorbed up to a third of the carbon dioxide we emit each year - but this climate buffer may be collapsing far sooner than a...

Over the past two years, the land carbon sink appears to have weakened dramatically, driving the largest one year jump in atmospheric CO2 on record in 2024. Is this the end of the land carbon sink? I asked around for @newscientist.com.

Scary news for West Coast friends in my latest for @science.org. Disturbed ocean sediments off California suggest big earthquakes on the Cascadia fault can trigger big quakes on the San Andreas. The "Big One" could well become the "Big Two"...
