The moon might be an even better gravitational wave detector than scientists expected. 🌕🌌 A new study in @physrevlett finds that variations in the moon's crust could amplify incoming space-time ripples by an average of 10% — and up to 10× in some regions. Read more: go.aps.org/3R7EqgG

Tomorrow is your last chance to comment on @whomb's proposed rule affecting the future of science. These APS leaders are just some of the 2,400+ people who have used our letter-writing portal to share what they think. Submit your comment: go.aps.org/4vbmWyB

Nobel laureate John Mather is one of thousands opposing a proposed federal rule that could affect science grant funding. "Peer review protects the public from attempts to corrupt," he writes. Read more public comments in #APSNews, then submit your own comment by July 13: go.aps.org/3RtXoy8

The future of science starts with today's students. A proposed federal rule could create new barriers for STEM education, training grants, and other programs that help launch scientific careers. Submit a public comment by July 13: go.aps.org/4vbmWyB

It’s your last chance to apply for the APS Committee on Education Award for Improving Undergraduate Physics Education. 🏆 Recognizing departments, programs, and networks making a sustained impact in undergraduate physics education. Apply by Aug. 7: go.aps.org/4cTRtul

Predicting the outcome of a #BlackHole merger usually requires supercomputers to solve Einstein's equations, but a new study in @physrevlett suggests a much simpler principle may capture the final state: maximizing entropy. 🔗 go.aps.org/4p8SaUN

Science doesn't happen in isolation. A proposed federal rule could make it harder for researchers to collaborate and participate in the scientific community. Tell leaders what you think by submitting a public comment before July 13: go.aps.org/4vbmWyB

A new study in @PhysRevLett suggests many #BlackHoles above 45 solar masses grew through a series of collisions between other black holes in dense star clusters — helping explain why some black holes are larger than stellar evolution models predict. 🔗 go.aps.org/4yd4KXA

🎆 Here's something you might not know: Fireworks don’t have to be earth-shakingly loud. Those sounds are engineered, just like the colors, to make the show more dramatic. Learn more surprising facts about fireworks in #APSNews: go.aps.org/4v1IWvb

International collaboration drives some of the world's biggest breakthroughs. Lindsay House explains how a proposed federal rule could make that collaboration more difficult — and what it could mean for scientific research. Submit a public comment: go.aps.org/4vbmWyB

How do molecules inside planets like Mars and Mercury behave? By compressing and heating iron sulfide, a Physical Review Materials study details a previously unknown phase of an alloy that may be a key part of a rocky planets’ solid core. Read the study: go.aps.org/3QAm1Jd

👏 More than 1,000 people have used our letter-writing portal to submit public comments on the proposed rule to insert political appointees into the scientific grant process. Submit yours: go.aps.org/4vbmWyB

Signs of #DarkMatter annihilation could be hiding in the halos of light around the gas giants of our solar system — and new bounds on dark matter masses and interactions could help future telescopes know where to find them. Read the @PhysRevLett study: journals.aps.org/prl/abstract/1…

Complex numbers have long seemed essential to #QuantumMechanics — but a paper in @PhysRevLett argues they may not be. By reformulating quantum theory using only real numbers, the authors show it can make the same experimentally-testable predictions: go.aps.org/4fURBM4

Mass extinctions occur when rates of environmental change outpace species' ability to adapt, suggests a new @PhysRevLett study that modeled distributions of species’ adaptation rates during mass extinction events over the past 450 million years: go.aps.org/4vqidJx

A new study in @PhysRevLett found that, starting from just a small number of physical axioms, a key equation describing string theory emerges — offering a new starting point for understanding quantum gravity through string theory. Read the paper: go.aps.org/3QYAoHg

A proposed federal rule would bring political appointees directly into grant-funding decisions. Lindsay House explains what that could mean for how science gets funded. Tell leaders what you think by submitting a public comment: go.aps.org/4vbmWyB
