Kirby Runyon is Ready to Go Interstellar. Is NASA?

The Interstellar Probe mission is designed to take humanity farther than anyone has gone before, no technological breakthroughs required.

A Sun's Eye View of the Solar System

If you could stand on the Sun and look out at Earth and the other planets, what would it look like?

Are Effect Sizes in Psychology Meaningless?

An argument that conceptual replications are more important than effect sizes

Photonics for artificial intelligence and neuromorphic computing

Scientists have given a fascinating new insight into the next steps to develop fast, energy-efficient, future computing systems that use light instead of electrons to process and store information - incorporating hardware inspired directly by the functioning of the human brain.

Citizen Scientists Discover Dozens of ‘Failed Stars’ Near Earth

Volunteers scanning the night sky for elusive hints of Planet Nine are uncovering the secrets of a strange class of worlds called brown dwarfs.

Dewdrops on a spiderweb reveal the physics behind cell structures

As any cook knows, some liquids mix well with each other, but others do not. For example, when a tablespoon of vinegar is poured into water, a brief stir suffices to thoroughly combine the two liquids. However, a tablespoon of oil poured into water will coalesce into droplets that no amount of stirring can dissolve. The physics that governs the mixing of liquids is not limited to mixing bowls; it also affects the behavior of things inside cells. It's been known for several years that some proteins behave like liquids, and that some liquid-like proteins don't mix together.

By changing their shape, some bacteria can grow more resilient to antibiotics

New research led by Carnegie Mellon University Assistant Professor of Physics Shiladitya Banerjee demonstrates how certain types of bacteria can adapt to long-term exposure to antibiotics by changing their shape. The work was published in the journal Nature Physics.

It's elemental: Ultra-trace detector tests gold purity

Unless radon gas is discovered in a home inspection, most people remain blissfully unaware that rocks like granite, metal ores, and some soils contain naturally occurring sources of radiation. In most cases, low levels of radiation are not a health concern. But some scientists and engineers are concerned about even trace levels of radiation, which can wreak havoc on sensitive equipment. The semiconductor industry, for instance, spends billions each year to source and "scrub" ultra-trace levels of radioactive materials from microchips, transistors and sensitive sensors.

The Asteroid Belt: Wreckage of a Destroyed Planet or Something Else?

The asteroid belt is a ring of debris that exists between Mars and Jupiter. What caused it to form — and will it ever become a planet?
