Surprising new way to kill cancer cells
Scientists have demonstrated that cancer cells -- and not normal cells -- can be killed by eliminating either the FAS receptor, also known as CD95, or its binding component, CD95 ligand. The discovery seems counterintuitive because CD95 has previously been defined as a tumor suppressor, scientists said.

The amazing anatomy of James Webb Space Telescope mirrors
When you think of a mirror, there really isn't that much needed to describe it, but when you look at a mirror that will fly aboard NASA's next-generation James Webb Space Telescope, there's a lot to the anatomy of a mirror.

New semiconductor holds promise for 2-D physics and electronics
Researchers at Berkeley Lab's Molecular Foundry have discovered a unique new semiconductor, rhenium disulfide, that behaves electronically as if it were a 2-D monolayer even as a 3-D bulk material. This not only opens the door to 2-D electronic applications with a 3D material, it also makes it possible to study 2-D physics with easy-to-make 3-D crystals.

Tiny transistors for extreme environs
University of Utah electrical engineers fabricated the smallest plasma transistors that can withstand high temperatures and ionizing radiation found in a nuclear reactor. Such transistors someday might enable smartphones that take and collect medical X-rays on a battlefield, and devices to measure air quality in real time.

Scientists open a new window into quantum physics with superconductivity in LEDs
A team of University of Toronto physicists led by Alex Hayat has proposed a novel and efficient way to leverage the strange quantum physics phenomenon known as entanglement. The approach would involve combining light-emitting diodes with a superconductor to generate entangled photons and could open up a rich spectrum of new physics as well as devices for quantum technologies, including quantum computers and quantum communication.

Getting rid of bad vibrations
Scanning electron microscopes are extremely sensitive, and even subtle movements going on around them can affect their accuracy. Vibration control tables already exist to dampen these sometimes barely perceptible disturbances. But now a new kind of isolation platform for the first time integrates sensors and actuators into the mount -- resulting in a platform that is more cost-effective and compact than its predecessors. Its designers will be showcasing this new form of isolation at the Hannover Messe (Hall 2, Booth D13) from April 7-11.

Antimony nanocrystals for batteries
Researchers from ETH Zurich and Empa have succeeded for the first time to produce uniform antimony nanocrystals. Tested as components of laboratory batteries, these are able to store a large number of both lithium and sodium ions. These nanomaterials operate with high rate and may eventually be used as alternative anode materials in future high-energy-density batteries.

Bright future for protein nanoprobes
Berkeley Lab researchers at the Molecular Foundry have discovered surprising new rules for creating ultra-bright light-emitting crystals that are less than 10 nanometers in diameter. These ultra-tiny but ultra-bright nanoprobes should be a big asset for biological imaging, especially deep-tissue optical imaging of neurons in the brain.

Roomy cages built from DNA
Scientists at the Harvard's Wyss Institute have built a set of self-assembling DNA cages one-tenth as wide as a bacterium. These DNA nanostructures are some of the largest and most complex structures ever constructed solely from DNA, and they could one day deliver drugs, or house tiny bioreactors or photonic devices that diagnose disease.

Can material rivaling graphene be mined out of rocks? Yes, if...
Will one-atom-thick layers of molybdenum disulfide, a compound that occurs naturally in rocks, prove to be better than graphene for electronic applications? There are many signs that might prove to be the case. But physicists from the Faculty of Physics at the University of Warsaw have shown that the nature of the phenomena occurring in layered materials are still ill-understood and require further research.
