River deltas, low-lying landforms that host critical and diverse ecosystems as well as high concentrations of human population, face an uncertain future. Even as some deltas experience decreased sediment supply from damming, others will see increased sediment discharge from land-use changes. Accurate estimates of the current rate of subsidence in the Mississippi Delta (southern USA) are important for planning wetland restoration and predictions of storm surge flooding.

A team of high school students analyzed data from the National Science Foundation's (NSF) Robert C. Byrd Green Bank Telescope (GBT) and discovered a never-before-seen pulsar which has the widest orbit of any around a neutron star - one among only a handful of double neutron star systems.

Pulsars are rapidly spinning neutron stars, the superdense remains of massive stars that have exploded as supernovas. As a pulsar spins, lighthouse-like beams of radio waves, streaming from the poles of its powerful magnetic field, sweep through space.

When one of these beams sweeps across the Earth, radio telescopes can capture the pulse of radio waves.

Psychologists have postulated that blaming victims, such as saying 'you were in the wrong place at the wrong time', is a defense mechanism that helps blamers feel the world is still just even when there is evidence it's not.

Therapeutic hypothermia has been successfully used to improve survival chances and reduce the risk of brain injury in adults after cardiac arrest and in newborn infants suffering from lack of oxygen but a large-scale study on the impact of body cooling in infants or children who have had cardiac arrest had not been done.

Automated organization, multi-RAT and multi-layer heterogeneous networks are being listed in mobile of 2020, at least by the kinds of committees that brought us bluetooth 7 years late. It's the 5G era, what vendors say will be the first meaningful unified wideband mobile communication system. 

A new paper suggests a need for a fundamental rethink of the evolutionary path of enzymes, the proteins vital to all life on Earth.

Enzymes catalyze a vast array of biologically relevant chemical reactions even in the simplest living cells but biochemist Dr. Wayne Patrick of University of Otago and colleagues assert that while people tend to imagine evolution as a slow and steady march, from barely functional life forms in the primordial soup towards a modern-day pinnacle of near perfection, that may not be true.
