Phys.org / 'Nu' citation index may bridge gap between productivity and impact metrics

Researchers propose a new citation index that balances productivity and impact in academic publishing. The h-index of citations was introduced in 2005 by physicist Jorge E. Hirsch. This index is defined simply as the maximum ...

Phys.org / Sinking boreal trees in the deep Arctic Ocean could remove billions of tons of carbon each year

Global efforts to reduce pollution will not be enough to mitigate the worst effects of climate change, scientists say. We will also need to extract over 10 gigatons of carbon dioxide from the atmosphere every year for the ...

Phys.org / Persistent shock wave around dead star puzzles astronomers

Gas and dust flowing from stars can, under the right conditions, clash with a star's surroundings and create a shock wave. Now, astronomers using the European Southern Observatory's Very Large Telescope (ESO's VLT) have imaged ...
