Combustion’s Mysterious 'QOOH' Radicals Exposed

Good news for those interested in accurately modeling combustion engines, scientists can now discriminate between previously unidentified radicals found in the early stages of the combustion process from similar compounds.

Seeing quantum motion; even one day ripples in the fabric of space-time?

Even large objects obey quantum physics, meaning they are never quite at rest. Researchers have developed a way to detect -- and manipulate -- this underlying quantum motion.

Stephen Hawking says he's solved a black hole mystery, but physicists await the proof

Physicist Stephen Hawking made a splash this week when he announced that he had solved a vexing conundrum that had puzzled generations of leading physicists - including the 73-year-old scientific superstar himself - for the better part of a half-century.

NASA Awards Contract for Construction of New Mission Launch Command Center at Wallops Flight Facility

NASA has awarded a contract to Harkins Contracting Inc. of Salisbury, Maryland, for the construction of a new Mission Launch Command Center (MLCC) at the agency’s Wallops Flight Facility in Wallops Island, Virginia.

NASA Concludes Series of Engine Tests for Next-Gen Rocket

NASA has completed the first developmental test series on the RS-25 engines that will power the agency’s new Space Launch System (SLS) rocket on missions deeper into space than ever before.

Your BS Detector for Warp Drives, Double Moons, and Other Implausible Claims

Today is the day when, according to a widely circulated email/Facebook hoax, Mars will appear as large in the sky as the full moon. In reality, nothing short of the catastrophic disruption of the entire solar system could allow such a thing to happen (and if that were happening, you probably would have heard the news). Still, I have sympathy for those who were taken in by the hoax. We live in an age of amazing space imagery: snapshots of nitrogen glaciers on Pluto, a robot bouncing off a com

Imaging techniques set new standard for super-resolution in live cells

Scientists can now watch dynamic biological processes with unprecedented clarity in living cells using new imaging techniques developed by researchers at the Howard Hughes Medical Institute's Janelia Research Campus. The new methods dramatically improve on the spatial resolution provided by structured illumination microscopy, one of the best imaging methods for seeing inside living cells.

Evidence suggests subatomic particles could defy the standard model

A team of physicists has found new hints of particles -- leptons, to be more precise -- being treated in strange ways not predicted by the Standard Model. The discovery could prove to be a significant lead in the search for non-standard phenomena.

Evidence suggests subatomic particles could defy the standard model

The Standard Model of particle physics, which explains most of the known behaviors and interactions of fundamental subatomic particles, has held up remarkably well over several decades. This far-reaching theory does have a few shortcomings, however—most notably that it doesn't account for gravity. In hopes of revealing new, non-standard particles and forces, physicists have been on the hunt for conditions and behaviors that directly violate the Standard Model.

Successful boron-doping of graphene nanoribbon

Physicists have succeeded in synthesizing boron-doped graphene nanoribbons and characterizing their structural, electronic and chemical properties. The modified material could potentially be used as a sensor for the ecologically damaging nitrogen oxides, scientists report.
