Super-puff planets almost shouldn't exist, seeming at first to defy the rules of gas giant formation. But like the unlikely planets themselves, "our explanations are actually holding together," one astrophysicist told me. Read on at @nytimes.com: www.nytimes.com/2026/07/17/s...

Rare Pair of Improbably Light ‘Super-Puff’ Planets Is Discovered (Gift Article)

They’re less dense than cotton candy, and they will help astrophysicists better understand the most unusual ways giant planets can form.

Scientists have found sugar in the space between stars, providing tantalizing clues into how life may have arisen on Earth. The discovery eluded scientists for decades. So I asked what's obviously the most important question: What does it taste like? www.nytimes.com/2026/07/13/s...

A Sweet Surprise: Scientists Find Sugar Deep in Our Galaxy (Gift Article)

It’s the first time a sugar molecule has been detected in interstellar space. The discovery provides tantalizing new clues into how life may have arisen on Earth.

Compared to the 1980s, California condors are thriving, but their numbers are still struggling: Without human-reared additions, their population would be shrinking. Lead is largely to blame, despite California's ban on lead-based ammo, a new study found. www.nationalgeographic.com/animals/arti...

California’s endangered condors have a surprising new foe

Researchers couldn’t figure out why the birds were dying — then they turned up an unusual suspect.

Last year, more than 600 dams—unwanted, unused or dangerous—were removed across Europe. The European Union set a goal of having 25,000 kilometers of free-flowing rivers by 2030, and dam removals are key to hitting that target. But they can be contentious. www.nationalgeographic.com/environment/...

Why Europe wants to tear down thousands of its dams

The continent has a growing movement to remove old and unnecessary dams to improve river health and save species. It comes as pressure on Europe’s water resources strengthens.

The Seattle fault zone runs right under its namesake city. In 923, it ruptured catastrophically. The threat of a repeat event on the main fault is still there. But two new studies show that smaller—but still damaging—quakes from shorter faults in the system are more likely. eos.org/articles/on-...

On the Seattle Fault, the Biggest Quakes Aren’t the Most Likely - Eos

Smaller quakes from secondary faults—which are not included in national seismic hazard modeling—occur more frequently than previously thought.

Dice games have been a key tool for social cohesion for many Native American cultures for thousands of years, as oral traditions, modern practices and archaeology reflect. The oldest documented dice are 12,000 years old and from the western US, a study finds. www.sciencenews.org/article/olde...

The oldest known dice in the world are roughly 12,000 years old

A study of ancient artifacts suggests Native American dice games began thousands of years earlier than previously documented.

It's hard to think about things that aren't politics in the U.S. right now, but for a bit of good news distraction: polar bears in Svalbard are fatter than scientists expected, suggesting they're coping with dramatic sea ice loss — for now. www.sciencenews.org/article/pola...

Polar bears in the Barents Sea are staying fat despite rapid sea ice loss

Polar bears can struggle to adapt to climate change. Bears on Svalbard may be surviving on land prey and seals — but scientists warn it may not last.

A new study argues that in the past, Cascadia quakes have triggered the San Andreas to go off, and that it could happen again. But other experts, while recognizing that may technically be possible, want more evidence. Read more at NatGeo: www.nationalgeographic.com/science/arti...

Are two of the deadliest earthquake zones in North America linked? It's possible—but controversial.

This is one of my favorite stories I've gotten to write. And it's that time of year again, when the skies in northwestern Washington are painted with squiggly black Vs of snow geese looking for a snack bar to settle down at for the winter. Just don't get hit by poop when you're looking up at them!

Us, peering out the window: "Look, sire. The snow geese are on the move." In honor of fall migration, we're reupping this gorgeous photo essay, with words by @rdzombak.bsky.social, about how Washington state is handling too much of a good thing. 🐦

Three DoD/NOAA satellites that help scientists track sea ice (and hurricanes) are slated to cease providing their data at the end of July due to "cybersecurity concerns." www.nytimes.com/2025/06/30/c...

🚨 Monday ice update - #Arctic sea ice extent is currently the *lowest* on record (JAXA data) • about 460,000 km² below the 2010s mean • about 1,210,000 km² below the 2000s mean • about 1,880,000 km² below the 1990s mean • about 2,550,000 km² below the 1980s mean More: zacklabe.com/arctic-sea-i...

Line graph time series of 2025's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with purple for the 1980s, blue for the 1990s, green for the 2000s, and white for the 2010s. Thin white lines are also shown for each year from 2000 to 2024. 2025 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between May and August by looking at the decadal average line positions.
