Highly fragile, volatile body observed with new quantum-mechanical measurement technique

Scientists have observed a highly fragile and volatile body through a new quantum-mechanical measurement technique.

Tiny magnets as a model system

In the microscopic world, everything is in motion: atoms and molecules vibrate, proteins fold, even glass is a slow flowing liquid. And during each movement there are interactions between the smallest elements – for example, the atoms – and their neighbors. To make these movements visible, scientists have developed a special model system. It is so big that it can be easily observed under an X-ray microscope, and mimics the tiniest movements in Nature. The model: rings made from six nanoscale magnetic rods, whose north and south poles attract each other.

New experiments set to detect gravitational waves

( —Over the next five years, Mansi Kasliwal writes in an astrophysics perspective in the journal Science, researchers will begin setting up experiments designed to detect gravitational waves. Kasliwal, an astronomer with the Observatories of the Carnegie Institution for Science located in Pasadena, California, says momentum is building in the physics community to find proof of the existence of gravitational waves. Thus, far, they are still considered theoretical.

How to frustrate a quantum magnet: 16 atomic ions simulate a quantum antiferromagnet

Scientists have explored how to frustrate a quantum magnet comprised of sixteen atomic ions – to date the largest ensemble of qubits to perform a simulation of quantum matter.

NASA Study Projects Warming-Driven Changes in Global Rainfall

A NASA-led modeling study provides new evidence that global warming may increase the risk for extreme rainfall and drought.

COUPP-60: New dark matter detector begins search for invisible particles

( —Scientists this week heard their first pops in an experiment that searches for signs of dark matter in the form of tiny bubbles. Scientists will need further analysis to discern whether dark matter caused any of the COUPP-60 experiment's first bubbles.

Mathematicians help to unlock brain function

( —Mathematicians from Queen Mary, University of London will bring researchers one-step closer to understanding how the structure of the brain relates to its function in two recently published studies.

NASA Opens New Era in Measuring Western U.S. Snowpack

A new NASA airborne mission has created the first maps of the entire snowpack of two major mountain watersheds in California and Colorado, producing the most accurate measurements to date of how much water they hold.

NASA Astrophysicist Elected to National Academy of Sciences

NASA astrophysicist Chryssa Kouveliotou, a senior scientist at NASA's Marshall Space Flight Center in Huntsville, Ala., has been selected for membership in the National Academy of Sciences, in recognition of her distinguished and continuing achievements in original scientific research.

Your Biggest Cosmic Questions, Answered (Part 1)

Fifteen years ago, a small cabal of researchers took some of the most firmly held notions about how the universe works and turned them on their head. Until then, everyone was sure that the expanding universe was born in an explosive Big Bang and had been slowing down ever since, dragged by the gravitational pull of untold billions of galaxies. But in fact the expansion is speeding up. Everyone was sure that matter was what dominated the overall behavior of the universe. But in fact it seems that
