A new thought experiment explores the interface between quantum mechanics and general relativity using the transfer of information.
Gecko feet-inspired dry adhesive could stick around
Inspired by microscopic hairs on gecko feet, scientists in South Korea have developed a shape-memory polymer that acts as a dry adhesive.
String theory fuzzballs resolve famous black hole paradox
Scientists have turned to string theory to better understand black holes, proposing they can be modeled as “fuzzballs” made up of interacting strings.
Where did all of Earth’s water come from?
A new study identifies that magnesium hydrosilicate, a compound present during the Earth’s formation, may be responsible for our planet’s abundant water.
Physicists identify a quantum membrane in merging black holes
The existence of a quantum membrane is predicted by some theories of gravity, and scientists might be one step closer to identifying one.

A 1913 manuscript by Albert Einstein and Michele Besso containing a precursor theory to general relativity sells at Paris auction.
What scientists hope to learn with the new James Webb Space Telescope
The new James Webb Space Telescope will collect infrared light from distant corners of the cosmos, enabling scientists to see further than ever before.
What is a black hole?
Regions of spacetime where gravity is so strong that nothing, not even light, can escape!
Fuel for thought — The future of Martian colonization
A biorefinery built on the Red Planet could help produce rocket fuel required for a return journey, but some snags need to be worked through first.
