The hemihelix: Scientists discover a new shape using rubber bands (w/ video)

While setting out to fabricate new springs to support a cephalopod-inspired imaging project, a group of Harvard researchers stumbled upon a surprising discovery: the hemihelix, a shape rarely seen in nature.

Mapping the road to quantum gravity

The road uniting quantum field theory and general relativity – the two great theories of modern physics – has been impassable for 80 years. Could a tool from condensed matter physics finally help map the way?

Economics = MC2—A portrait of the modern physics startup

For much of the 20th century, many of the technological innovations that drove U.S. economic growth emerged from "idea factories" housed within large companies—research units like Bell Labs or Xerox PARC that developed everything from the transistor to the computer mouse.

Superconducting qubit array points the way to quantum computers

A fully functional quantum computer is one of the holy grails of physics. Physicists have moved one step closer to making a quantum computer a reality by demonstrating a new level of reliability in a five-qubit array. Quantum computing is anything but simple. It relies on aspects of quantum mechanics such as superposition. This notion holds that any physical object, such as an atom or electron -- what quantum computers use to store information -- can exist in all of its theoretical states simultaneously. This could take parallel computing to new heights.

Atomic switcheroo explains origins of thin-film solar cell mystery

Treating cadmium-telluride (CdTe) solar cell materials with cadmium-chloride improves their efficiency, but researchers have not fully understood why.

Halving hydrogen: First view of nature-inspired catalyst after ripping hydrogen apart provides insights for better fuel cells

A fuel cell catalyst that converts hydrogen into electricity must tear open a hydrogen molecule. Now researchers have captured a view of such a catalyst holding onto the two halves of its hydrogen feast, provides insight into how to make the catalyst work better.

Physicist demonstrates dictionary definition was dodgy

It is the defining moment that demonstrates a QUT physicist was correct in pointing out a 99-year-old mistake to one of the world's most authoritative dictionaries.

Steering chemical reactions with laser pulses

With ultra-short laser pulses, chemical reactions can be controlled at the Vienna University of Technology. Electrons have little mass and are therefore influenced by the laser, whereas the atomic nuclei are much heavier and are hardly affected.

NASA Astronauts to Call Colorado Students from Space

Cadets and students from the U.S. Air Force Academy and the Jack Swigert Aerospace Academy Magnet School in Colorado will gather at 11:50 a.m. EDT Thursday, April 24, to speak live with astronauts currently aboard the International Space Station.
