Undergraduates Hunt for Special Tetrahedra That Fit Together
A group of MIT undergraduates is searching for tetrahedra that tile space, the latest effort in a millennia-long inquiry. They’ve already made a new discovery.
Some Proteins Change Their Folds to Perform Different Jobs
Unusual proteins that can quickly fold into different shapes provide cells with a novel regulatory mechanism.
‘Unicorn’ Discovery Points to a New Population of Black Holes
Small black holes were nowhere to be found, leading astronomers to wonder if they didn’t exist at all. Now a series of findings, including a “unicorn” black hole, has raised hopes of solving the decade-long mystery.
Physicists Study How Universes Might Bubble Up and Collide
Since they can’t prod actual universes as they inflate and bump into each other in the hypothetical multiverse, physicists are studying digital and physical analogs of the process.
Plant Cells of Different Species Can Swap Organelles
In grafted plants, shrunken chloroplasts can jump between species by slipping through unexpected gateways in cell walls.
The Curious Strength of a Sea Sponge’s Glass Skeleton
A glass sponge found deep in the Pacific shows a remarkable ability to withstand compression and bending, on top of the sponge’s other unusual properties.
Galaxy-Size Bubbles Discovered Towering Over the Milky Way
For decades, astronomers debated whether a particular smudge was close-by and small, or distant and huge. A new X-ray map supports the massive option.
New Quantum Algorithms Finally Crack Nonlinear Equations
Two teams found different ways for quantum computers to process nonlinear systems by first disguising them as linear ones.
