Physicists Close In on ‘Perfect’ Optical Lens
Researchers are making progress toward a “perfect lens” that will be able to resolve an organelle assembling a protein or a virus attacking a cell.
As Machines Get Smarter, Evidence They Learn Like Us
Studies show that computer models called "neural networks" behave strikingly similar to actual brains when performing certain tasks, suggesting the two may learn in the same way.
Signs of a Stranger, Deeper Side to Nature’s Building Blocks
New findings suggest that beneath the surface of quantum theory lies a vibrant string theory world where some matter corresponds to black holes in higher dimensions.
In Lopsided Map of the Cosmos, a Glimmer of Its Origins
Theoretical cosmologists are piecing together a cosmic origin story from a surprising anomaly in the recently released Planck satellite image.
Is Nature Unnatural?
Decades of confounding experiments have physicists considering a startling possibility: The universe might not make sense.
Perpetual Motion Test Could Amend Theory of Time
A radical theory predicting the existence of “time crystals” — perpetual motion objects that break the symmetry of time — is being put to the test.
Scientists Parse Ocean’s Dynamic Role in Climate Change
New data collected by mathematicians and oceanographers in the frigid waters of the Southern Ocean could dramatically improve climate models.
Solid or Liquid? Physicists Redefine States of Matter
Glass and other strange materials have long confounded textbook definitions of what it means to be solid. Now, two groups of physicists propose a new solution to the riddle.
Treading Softly in a Connected World
In an increasingly interconnected world, scientists are seeking safeguards against catastrophic cascades of failure like stock market crashes and widespread blackouts.
