SolidEnergy Systems' battery (far right) is twice as energy-dense, yet just as safe and long-lasting as the lithium ion batteries used in consumer electronics. The battery uses a lithium metal foil for an anode, which can hold more ions and is several times thinner and lighter than traditional lithium metal, graphite, carbon, or silicon anodes. A novel electrolyte also keeps the battery from heati...

Researchers designed and tested several types of optical sensors that could be placed at the tip of an epidural needle and determined that the best is one that relies on Raman spectroscopy. This technique, which uses light to measure energy shifts in molecular vibrations, offers detailed information about the chemical composition of tissue.

The IceCube Neutrino Observatory is a huge, cubic-kilometer particle detector buried deep under the ice at the South Pole. After analyzing 20,000 neutrinos detected over the span of a year at the observatory, scientists were unable to observe any sign of sterile, or “hidden,” neutrinos.

Neutrino search finds no evidence of “hidden” particle

If discovered, sterile neutrinos may explain dark matter.

In a new concept for battery cathodes, nanometer-scale particles made of lithium and oxygen compounds (depicted in red and white) are embedded in a sponge-like lattice (yellow) of cobalt oxide, which keeps them stable. The researchers propose that the material could be packaged in batteries that are very similar to conventional sealed batteries yet provide much more energy for their weight.
