Today, almost the whole accelerator complex is operational and providing beams to all the experimental facilities as scheduled. The LHC experiments are taking data, while the LHC is nearing the end of...
When a star swallows a planet, does it belch? Leave crumbs? Get bigger? No one could say for sure because no one had witnessed it — until now.

The subject of Diophantine approximation studies how a real vector is approximated by rational vectors. Diophantine sets are subsets of real vectors defined by certain approximate functions. Among the...
During the last few years, CRISPR has grabbed headlines for helping treat patients with conditions as varied as blindness and sickle cell disease. However, long before humans co-opted CRISPR to fight ...
The melting of polar ice is not only shifting the levels of our oceans, it is changing the planet Earth itself. Newly minted Ph.D. Sophie Coulson and her colleagues explained in a recent paper in Geop...
The Millennium Drought (southeastern Australia) provided a natural experiment to challenge the assumption that watershed streamflow always recovers from drought.
