Controlling fast X-ray pulses with laser light
When hit by light, electrons are excited and begin to move. Ultrafast X-ray pulses may make it possible to watch the motion of these electrons as they move inside and between atoms in a material. Although scientists have gotten much better at making ultrafast X-rays in recent years, controlling them is still notoriously difficult. Researchers at Louisiana State University and Lund University in Sweden have demonstrated a new method to direct short bursts of X-ray light that uses strong laser pulses.

Electro-optical switch transmits data at record-low temperatures
A silicon optical switch newly developed at Sandia National Laboratories is the first to transmit up to 10 gigabits per second of data at temperatures just a few degrees above absolute zero. The device could enable data transmission for next-generation superconducting computers that store and process data at cryogenic temperatures.

UNC researchers make discovery that could increase plant yield in wake of looming phosph
Scientists at the University of North Carolina at Chapel Hill have pinpointed a key genetic switch that helps soil bacteria living on and inside a plant's roots harvest a vital nutrient with limited global supply. The nutrient, phosphate, makes it to the plant's roots, helping the plant increase its yield.

When proteins court each other, the dance moves matter
Proteins shake their bodies and wave their limbs -- essentially dancing -- all with the goal of optimizing their interaction with other molecules, including other proteins. A new study shows that, in biological courtship, dance moves matter. The findings help to lay a foundation for the development of drugs targeting molecular vibrations. Such pharmaceuticals would block proteins from carrying out tasks that contribute to disease.

Mapping the effects of crystal defects
MIT research offers insights into how crystal dislocations -- a common type of defect in materials -- can affect electrical and heat transport through crystals, at a microscopic, quantum mechanical level. A new mathematical approach to analyzing these dislocations uses a new quasiparticle called a dislon.

Louisiana wetlands struggling with sea-level rise 4 times the global average
Without major efforts to rebuild Louisiana's wetlands, particularly in the westernmost part of the state, there is little chance that the coast will be able to withstand the accelerating rate of sea-level rise, a new Tulane University study concludes.

New way to tune electronic energy levels may lead to valleytronic devices
Faster, more efficient data storage and computer logic systems could be on the horizon thanks to a new way of tuning electronic energy levels in two-dimensional films of crystal, discovered by researchers at MIT. The discovery could ultimately pave the way for the development of so-called "valleytronic" devices, which harness the way electrons gather around two equal energy states, known as valleys.

How CSU chemists are helping us not get food poisoning
Borrowing concepts from medical diagnostic devices, Colorado State University chemists have created a simple, cheap set of handheld tests that can detect the presence of many water or food-borne pathogens. If applied in the field, such tests could greatly reduce the number of expensive follow-up tests needed to keep the food supply safe from fecal contamination.

Transforming the carbon economy
A task force commissioned in 2016 by former US Secretary of Energy Ernest Moniz has proposed a framework for evaluating R&D on recycling carbon dioxide and removing large amounts of CO2 from the atmosphere. The goal is to produce a global emissions reduction of at least 1 billion tons of CO2 per year.

New delta Scuti: Rare pulsating star 7,000 light years away is 1 of only 7 in Milky Way
The newest delta Scuti (SKOO-tee) star in our night sky is so rare it's only one of seven identified by astronomers in the Milky Way. Discovered at Southern Methodist University in Dallas, the star -- like our sun -- is in the throes of stellar evolution, to conclude as a dying ember in millions of years. Until then, the exceptional star pulsates brightly, expanding and contracting from heating and cooling of hydrogen burning at its core.

UMD physicist improves method for designing fusion experiments
University of Maryland physicist Matt Landreman has made an important revision to a software tool used to design fusion experiments known as stellarators. The new method results in designs that create a magnetic field suitable for confining blazing-hot plasma, while allowing better access for repairs and more places to install sensors. Landreman's new method is described in a paper published Feb. 13, 2017 in the journal Nuclear Fusion.
