HAWC Gamma-ray Observatory reveals new look at the very-high-energy sky
Today, scientists operating the High Altitude Water Cherenkov (HAWC) Gamma-ray Observatory released a new survey of the sky made from the highest energy gamma rays ever observed. The new sky map, which uses data collected since the observatory began running at full capacity last March, offers a deeper understanding of high-energy processes taking place in our galaxy and beyond.

Bigger brains led to bigger bodies in our ancestors
New research suggests that humans became the large-brained, large-bodied animals we are today because of natural selection to increase brain size. The work contradicts previous models that treat brain size and body size as independent traits. Instead, the study shows that brain size and body size are genetically linked and that selection to increase brain size will 'pull along' body size.

Researcher pioneers bacterial infection treatment using novel target: Vesicles
Angela Brown, assistant professor of chemical and biomolecular engineering at Lehigh University, is pioneering a unique approach to treating bacterial infections focused on a novel target: outer membrane vesicle -- which are regularly shed by Gram negative bacteria, among the most challenging type of bacteria to treat. Her work has caught the attention of the National Science Foundation, which recently awarded her an NSF CAREER grant to fund the development of this transformative approach.

A new way to get electricity from magnetism
By showing that a phenomenon dubbed the 'inverse spin Hall effect' works in several organic semiconductors -- including carbon-60 buckyballs -- University of Utah physicists changed magnetic 'spin current' into electric current. The efficiency of this new power conversion method isn't yet known, but it might find use in future electronic devices including batteries, solar cells and computers.

Which trees face death in drought?
William Anderegg and his colleagues looked for patterns in previous studies of tree mortality and found some common traits that characterized which species lived and which died during drought. The results, published today in Proceedings of the National Academy of Sciences, can help chart the future of forests.

Chemical weathering controls erosion rates in rivers
Chemical weathering can control how susceptible bedrock in river beds is to erosion, according to new research. In addition to explaining how climate can influence landscape erosion rates, the results also may improve scientists' ability to interpret and predict feedbacks between erosion, plate tectonics and Earth's climate. The research, led by The University of Texas at Austin, was published in Nature on April 14, 2016.

Electrons slide through the hourglass on surface of bizarre material
A new state of matter in which current flows only through a set of surface channels that resemble an hourglass is the subject of new research by a team at Princeton University. The team theorized that a new particle, the 'hourglass fermion,' is responsible for this current flow. The tuning of the material's properties can sequentially create and destroy the hourglass fermions, suggesting a range of potential applications such as efficient transistor switching.
