What Causes Alzheimer’s? Scientists Are Rethinking the Answer.
After decades in the shadow of the reigning model for Alzheimer’s disease, alternative explanations are finally getting the attention they deserve.
New Chip Expands the Possibilities for AI
An energy-efficient chip called NeuRRAM fixes an old design flaw to run large-scale AI algorithms on smaller devices, reaching the same accuracy as wasteful digital computers.
How Supergenes Fuel Evolution Despite Harmful Mutations
Supergenes that lock inherited traits together are widespread in nature. Recent work shows that their blend of genetic benefits and risks for species can be complex.
Brightest-Ever Space Explosion Reveals Possible Hints of Dark Matter
A recent gamma-ray burst known as the BOAT — “brightest of all time” — appears to have produced a high-energy particle that shouldn’t exist. For some, dark matter provides the explanation.
Inside the Proton, the ‘Most Complicated Thing You Could Possibly Imagine’
The positively charged particle at the heart of the atom is an object of unspeakable complexity, one that changes its appearance depending on how it is probed.
High-Temperature Superconductivity Understood at Last
A new atomic-scale experiment all but settles the origin of the strong form of superconductivity seen in cuprate crystals, confirming a 35-year-old theory.
Record-Breaking Robot Highlights How Animals Excel at Jumping
Robots can surpass the limitations on how high and far animals can jump, but their success only underscores nature’s ingenuity in making the most of what’s available.
A Good Memory or a Bad One? One Brain Molecule Decides.
When the brain encodes memories as positive or negative, one molecule determines which way they will go.
Old Problem About Mathematical Curves Falls to Young Couple
Eric Larson and Isabel Vogt have solved the interpolation problem — a centuries-old question about some of the most basic objects in geometry. Some credit goes to the chalkboard in their living room.
