Had the famously silly Ig Nobel ceremony not moved outside of the U.S., “I would have thought twice” before attending this year, said one new winner. “The perception I have is that there is not so much of a welcoming culture anymore.” 🔬🏅 Read more in @science.org: www.science.org/content/arti...

Ig Nobel hosts science’s silliest ceremony outside U.S. for first time

The indefinite move to Europe was a response to travel and safety concerns for winners

3% of a giant Western Australian forest died in a record drought in 2023-24. Now, scientists have used the damage to develop a surprising new tool for predicting future die-offs: gamma rays.🌲⚡ Read more in @science.org: www.science.org/content/arti... #tree #forest #drought #climate #climatechange

To predict tree death, scientists tapped gamma rays to peer underground

Airborne radiation sensors could help forecast and prevent drought-driven tree mortality

16,000 satellites currently whiz above our heads; 1.7 million more are proposed. A new preprint looks into a dystopian, runaway space junk threshold called Kessler syndrome—and finds that many popular megaconstellation proposals breach it. 🛰️🚨 For @science.org: www.science.org/content/arti...

Planned satellite megaconstellations could generate runaway space debris

Modeling suggests infamous “Kessler syndrome” would make the swarms unsustainable

If Pluto's downgrade got you upset, brace yourself: Uranus and Neptune might not be real "ice giants." 🧊🚫🪐 Research increasingly shows our outermost planets are far rockier than thought—and maybe even full of magma oceans.🔥 Read more @science.org : www.science.org/content/arti... #space #nasa

Uranus and Neptune may not be ‘ice giants’ after all

A growing number of theories propose Uranus and Neptune are rocky worlds

Father's Day must be on astronomers' minds—new JWST data makes famed interstellar comet 3I/ATLAS a galactic "granddad," one scientist says. 🪨👴 Read more about this 12-billion-year-old interstellar interloper today in @science.org: www.science.org/content/arti... #nasa #jwst #space

Interstellar comet is unlike anything seen in our Solar System

Chemical signature of 3I/ATLAS suggests it formed early in the history of the Milky Way

“I grew up thinking that [sustained lunar presence] was going to be something that happened 20 years ago,” said one lunar scientist. “I’m just really happy that they are moving forward with it.”🚀🌑 Read more in @skyandtelescope.bsky.social about NASA's ambitious Moon Base plans: tinyurl.com/3hhdbtjk

NASA Brings Its Lunar Ambitions into Focus with Moon Base Missions

Rovers, drones, and landers will usher in a sustained lunar presence, under the new plan NASA announced this week.

What swims, hops, and explores all over? 🛟 🌊 The small, neon submersibles of Orpheus Ocean, facing their biggest test yet: a NOAA collab to explore 8,000 square nautical miles of seafloor and its potential mineral stores. Read more in my first story for @technologyreview.com: tinyurl.com/2s3fcmah

Inexpensive seafloor-hopping submersibles could stoke deep-sea science—and mining

A company called Orpheus Ocean wants to go “deep for cheap.”

“I’m not saying they can’t do it. It’s just unheard of."🚀☢️ Dove deep into NASA's mission to bring a 60-year nuclear dream to reality in 32 months for @science.org. Check it out for hints at where its fission reactor might be built—and who provided input on the mission, anyway: tinyurl.com/3627nvmp

BIG story out now from @science.org on SR-1 Freedom, a highly ambitious nuclear Mars mission that NASA wants to launch in 2028. @hannah-richter.bsky.social has scoops on how the mission came together—and where its reactor is probably being built. www.science.org/content/arti...

Bubbly magma spurs volcanic eruptions...or does it? 🫧🌋 New research proposes that our longstanding theory is backwards: it's bubbles disappearing that does the trick. “That is a paradigm shift...in triggering volcanic eruptions," said one researcher. Today in @science.org: tinyurl.com/mr39x5kn

Long-standing volcanic eruption theory might be backward

Eruptions could be triggered when bubbles vanish into magma—not when they burst out

“I expect at some point” that the ceremony will make its way back across the pond, says Ig Nobel founder Marc Abrahams. But “the way things are right now, I doubt that the ceremony will be back in the U.S. in any of the next few years.” Nice coverage by @hannah-richter.bsky.social for @science.org

After 35 years, Ig Nobel ceremony to leave the U.S.

Finances and Trump policies underlaid the decision to move the satirical science event to Switzerland

“We were aware that we might have a similar situation this year,” the Ig Nobel founder said after Trump's border policies prompted 4/10 winning teams to decline traveling in 2025. "Then the situation got far worse.” Read about the Igs' decision to move abroad @science.org: tinyurl.com/3kfrdh7y
