Nitrogen fixation in ambient conditions
Scientists have developed a uranium-based complex that allows nitrogen fixation reactions to take place in ambient conditions. The work lays the foundation to develop new processes for synthesizing nitrogen products like cyanamide.

Planetary boundaries for antibiotic and pesticide resistance identified
Researchers have now published the first estimates of antibiotic and pesticide 'planetary boundaries.' The researchers suggest that if resistance to antibiotics and pesticides goes beyond these boundaries, societies risk large-scale health and agricultural crises. The results indicate one group of bacteria has passed a boundary.

Study opens route to ultra-low-power microchips
Researchers have developed a new way of controlling magnetism in materials, which could lead to new low-power technologies for memory, computing, and sensing devices.

Insufficient sleep in children is associated with poor diet, obesity and more screen time
A new study conducted among more than 177,000 students suggests that insufficient sleep duration is associated with an unhealthy lifestyle profile among children and adolescents.

Alpine ice shows three-fold increase in atmospheric iodine
Analysis of iodine trapped in Alpine ice has shown that levels of atmospheric iodine have tripled over the past century, which partially offsets human-driven increases in the air pollutant, ozone.

Small molecules: From beaker to solved 3D structure in minutes
A new method for learning the structures of small molecules, such as hormones, is 'like science fiction.'

New framework pushes the limits of high-performance computing
Researchers found a way to give high-performance computing data systems the flexibility to thrive with a first-of-its-kind framework called BespoKV, perhaps helping to one day achieve the HPC goal of performing at the exascale, or a billion billion calculations per second.

Escape responses of coral reef fish obey simple behavioral rules
The escape response to evade perceived threats is a fundamental behavior seen throughout the animal kingdom, and laboratory studies have identified specialized neural circuits that control this behavior. To understand how these neural circuits operate in complex natural settings, researchers recorded and analyzed escape responses in wild coral reef fish. Their results show how a sequence of well-defined decision rules generates evasion behavior in a wide range of coral reef fish species.

Primates of the Caribbean: Ancient DNA reveals history of mystery monkey
Analysis of ancient DNA of a mysterious extinct monkey named Xenothrix -- which displays bizarre body characteristics very different to any living monkey -- has revealed that it was in fact most closely related to South America's titi monkeys (Callicebinae). Having made their way overwater to Jamaica, probably on floating vegetation, their bones reveal they subsequently underwent remarkable evolutionary change.

Streamside forests store tons of carbon
Researchers have compiled carbon storage data from 117 publications, reports, and other data sets on streamside forests around the world. Researchers found that the average amount of carbon stored in mature streamside forest rivals the highest estimates for any other forest type around the world, such as tropical or boreal forests.
