New tools allow rapid ID of CRISPR-Cas system PAMs
CRISPR-Cas systems are widely heralded as a new generation of genetic tools. But development of these tools requires researchers to identify the protospacer-adjacent motifs that unlock each system's functionality. A new set of techniques expedites PAM identification -- and early testing finds that many CRISPR-Cas systems actually have multiple PAMs of varying strength.

Tracking 'marine heatwaves' since 1950 -- and how the 'blob' stacks up
A tally of Northern Hemisphere marine heatwaves since 1950 shows that prolonged warm periods have recurred regularly in the past, but are being pushed into new territory by climate change.

Second quantum revolution a reality with chip-based atomic physics
A University of Oklahoma-led team of physicists believes chip-based atomic physics holds promise to make the second quantum revolution -- the engineering of quantum matter with arbitrary precision -- a reality. With recent technological advances in fabrication and trapping, hybrid quantum systems are emerging as ideal platforms for a diverse range of studies in quantum control, quantum simulation and computing.

Seventh-graders learn astrophysics through mixed-reality computer simulation

Starvation as babies makes bees stronger as adults
Arizona State University researchers have discovered that short-term starvation as larvae (baby bees) actually makes honey bees more resilient to nutritional deprivation as adults. This is the first time that an anticipatory mechanism, called 'predictive adaptive response,' has been found in social organisms.

Sea-level rise from Antarctic ice sheet could double
An ice sheet model that includes previously underappreciated processes indicates that sea level may rise almost 50 feet by 2500 due to Antarctic ice sheet melting if greenhouse gas emissions continue unabated, according to researchers from Penn State and University of Massachusetts, Amherst.

Mystery of broadbills' wing song revealed
Broadbills make an unusual klaxon-like call during territorial flights, but it was not clear how the birds produced the sound until a team of scientists from Yale University and the University of Cyprus filmed the birds in the wild in Africa. They discovered that the remarkable sound is caused by the sixth and seventh primary feathers on the wing vibrating when the wing tip reaches speeds of 16m/s during each down wingbeat.

Mimicking a blood vessel to create a 'bridge' to better medicine and precision treatment
A team of researchers at Lehigh University and the University of Pennsylvania has developed a technique to observe cell to cell interaction at the nanoscale under micro-fluid conditions. They have successfully applied the technique to the study of blood vessel inflammation, a condition that sets the stage for heart disease, the number one cause of death in the US and globally. Their findings have been published in Biomicrofluidics.

Researchers develop new method of trapping multiple particles using fluidics
Precise control of an individual particle or molecule is a difficult task. Controlling multiple particles simultaneously is an even more challenging endeavor. Researchers at the University of Illinois have developed a new method that relies on fluid flow to manipulate and assemble multiple particles. This new technique can trap a range of submicron- to micron-sized particles, including single DNA molecules, vesicles, drops or cells.
