Researchers have always known that waves were an important part of the cliff erosion process, but they haven't been able to separate the influence of waves and rain before. After decades of debate over the differing roles that both play, new findings provide an opportunity to improve forecasts.

A number of Americans have died during encounters with police officers who used chokeholds and other forms of neck restraint. Neurologist argue that some police departments justify use of these tactics with misleading language and that the use of neck restraints has no medical justification.

This Viewpoint reviews the potential neurologic consequences of any restriction of blood flow or oxygen to the brain and calls for an examination of the safety and appropriateness of the use of neck restraints by law enforcement.

In a recent study, researchers from Imperial College London developed a model to assess the effect of different measures used to curb the spread of the coronavirus. However, the model had fundamental shortcomings and cannot be used to draw the published conclusions, claim Swedish researchers from Lund University, and other institutions, in the journal Nature.

Using mathematical modeling, new interdisciplinary research from the lab of Arye Nehorai, the Eugene & Martha Lohman Professor of Electrical Engineering in the Preston M. Green Department of Electrical & Systems Engineering at Washington University in St. Louis, determines the best course of action when it comes to walking the line between economic stability and the best possible health outcomes.

The lockdowns that resulted from the COVID-19 pandemic have reduced greenhouse gas emissions. However, in the recovery phase, emissions could rise to levels above those projected before the pandemic. It all depends on how the stimulus money that governments inject into their economies is spent. A team of scientists, led by Dr. Yuli Shan and Professor Klaus Hubacek, University of Groningen, has quantified how different recovery scenarios may affect global emissions and climate change.
