In a finding that reveals an entirely new state of matter, research shows that Cooper pairs, electron duos that enable superconductivity, can also conduct electricity like normal metals do.

Researchers are developing a sensor the size of a Band-Aid that will measure a baby's blood oxygen levels, a vital indication of the lungs' effectiveness and whether the baby's tissue is receiving adequate oxygen supply. Unlike current systems used in hospitals, this miniaturized wearable device will be flexible and stretchable, wireless, inexpensive, and mobile -- possibly allowing the child to leave the hospital and be monitored remotely.

Researchers have built a compact device, the size of a shoebox, that produces a terahertz laser whose frequency they can tune over a wide range. The device is built from commercial, off-the-shelf parts and is designed to generate terahertz waves by spinning up the energy of molecules in nitrous oxide, or, as it's more commonly known, laughing gas.

In a miniaturized laboratory, microfluidic systems can conduct chemical experiments on a chip through a series of small connected tubes the size of a hair.

Light can be directed in different directions, usually also back the same way. Physicists have however succeeded in creating a new one-way street for light. They cool photons down to a Bose-Einstein condensate, which causes the light to collect in optical 'valleys' from which it can no longer return. The findings could also be of interest for the quantum communication of the future.

Catalysts accelerate chemical reactions, but the widely used metal platinum is scarce and expensive. Researchers have now developed an alternative with a 20x higher activity: a catalyst with hollow nanocages of an alloy of nickel and platinum. Researchers want to use this new catalyst to develop a refrigerator-size electrolyzer of about 10 megawatts in the future.

Researchers have developed an optical switch that routes light from one computer chip to another in just 20 billionths of a second -- faster than any other similar device. The compact switch is the first to operate at voltages low enough to be integrated onto low-cost silicon chips and redirects light with very low signal loss.

Even by the wild standards of the outer solar system, the strange orbits that carry Neptune's two innermost moons are unprecedented, according to newly published research.
