Ann Nelson Took On the Biggest Problems in Physics
Posted on Thursday August 22, 2019

The theoretical particle physicist Ann Nelson, who died on August 4 at age 61, was a font of brilliant ideas and a champion of ending discrimination in the field.

A Mathematical Model Unlocks the Secrets of Vision
Posted on Wednesday August 21, 2019

Mathematicians and neuroscientists have created the first anatomically accurate model that explains how vision is possible.

The Puzzling Search for Perfect Randomness
Posted on Tuesday August 20, 2019

Does objective, perfect randomness exist, or is randomness merely a product of our ignorance?

Can New Species Evolve From Cancers? Maybe. Here’s How.
Posted on Monday August 19, 2019

Researchers agree it’s a long shot, but transmissible cancers could theoretically evolve into independent species. Certain weird parasites might be living proof.

To Make Two Black Holes Collide, Try Three
Posted on Thursday August 15, 2019

How do black holes merge and make gravitational waves? Maybe with a little help from their friends.

Light-matter interaction without interference
Posted on Saturday August 24, 2019

Quantum dots might constitute the foundation of quantum communication. They are an efficient interface between matter and light, with photons emitted by the quantum dots transporting information across large distances. However, structures form by default during the manufacture of quantum dots that interfere with communication. Researchers have now successfully eliminated these interferences.

Laser-produced uranium plasma evolves into more complex species
Posted on Friday August 23, 2019

Mapping the evolution of complex uranium oxide species has practical applications from Mars exploration to nuclear proliferation detection.

Analytical tool designs corkscrew-shaped nano-antennae
Posted on Friday August 23, 2019

Researchers have derived analytically how corkscrew-shaped nano-antennas interact with light.

Study models new method to accelerate nanoparticles
Posted on Friday August 23, 2019

Researchers have modeled a method to manipulate nanoparticles as an alternative mode of propulsion for tiny spacecraft that require very small levels of thrust. The team simulated a system that uses light to generate an electromagnetic field to move the particles from a reservoir, funneled through an injector, then shot out of an accelerator to produce thrust.

In a quantum future, which starship destroys the other?
Posted on Thursday August 22, 2019

Quantum mechanics boasts all sorts of strange features, one being quantum superposition -- the peculiar circumstance in which particles seem to be in two or more places or states at once. Now, an international group of physicists flip that description on its head, showing that particles are not the only objects that can exist in a state of superposition -- so can time itself.
