Putting hydrogen on solid ground: Simulations with a machine learning model predict a new phase of solid hydrogen      (via sciencedaily.com)     Original source 

Hydrogen, the most abundant element in the universe, is found everywhere from the dust filling most of outer space to the cores of stars to many substances here on Earth. This would be reason enough to study hydrogen, but its individual atoms are also the simplest of any element with just one proton and one electron.

X-ray analysis sheds new light on prehistoric predator's last meal      (via sciencedaily.com)     Original source 

We now know more about the diet of a prehistoric creature that grew up to two and a half meters long and lived in Australian waters during the time of the dinosaurs, thanks to the power of x-rays. Researchers used micro-CT scans to peer inside the fossilized stomach remains of a small marine reptile -- a plesiosaur nicknamed 'Eric' after a song from the comedy group Monty Python -- to determine what the creature ate in the lead up to its death.

Physicists find unusual waves in nickel-based magnet      (via sciencedaily.com)     Original source 

Perturbing electron spins in a magnet usually results in excitations called 'spin waves' that ripple through the magnet like waves moving across the surface of a pond that's been struck by a pebble. Physicists have now discovered dramatically different excitations called 'spin excitons' that can also 'ripple' through a nickel-based magnet as a coherent wave.

Chemists propose ultrathin material for doubling solar cell efficiency      (via sciencedaily.com)     Original source 

Researchers are studying radical new ways to improve solar power and provide more options for the industry to explore. Chemists are proposing to make solar cells using not silicon, but an abundantly available natural material called molybdenum disulfide. Using a creative combination of photoelectrochemical and spectroscopic techniques, the researchers conducted a series of experiments showing that extremely thin films of molybdenum disulfide display unprecedented charge carrier properties that could someday drastically improve solar technologies.

The diversity of present tree species is shaped by climate change in the last 21,000 years      (via sciencedaily.com)     Original source 

A new global survey of 1000 forest areas shows how climate change since the peak of the last ice age has had a major impact on the diversity and distribution of tree species we see today. The results can help us predict how ecosystems will react to future changes, thus having an impact on conservation management around the globe.

Teasing strange matter from the ordinary      (via sciencedaily.com)     Original source 

In a unique analysis of experimental data, nuclear physicists have made observations of how lambda particles, so-called 'strange matter,' are produced by a specific process called semi-inclusive deep inelastic scattering (SIDIS). What's more, these data hint that the building blocks of protons, quarks and gluons, are capable of marching through the atomic nucleus in pairs called diquarks, at least part of the time.

Physicists discover transformable nano-scale electronic devices      (via sciencedaily.com)     Original source 

The nano-scale electronic parts in devices like smartphones are solid, static objects that once designed and built cannot transform into anything else. But physicists have reported the discovery of nano-scale devices that can transform into many different shapes and sizes even though they exist in solid states.
