For cells, some shapes are easier to swallow than others

18-May-2016

Scientists have probed the process that allows cells to swallow up particles, finding that some shapes are easier to swallow than others. Cells take in small particles and other objects such as bacteria in a process called engulfment. Single-celled organisms use engulfment to take in food, while ...

Physicists Measure van der Waals Forces of Individual Atoms for the First Time

17-May-2016

Physicists at the Swiss Nanoscience Institute and the University of Basel have succeeded in measuring the very weak van der Waals forces between individual atoms for the first time. To do this, they fixed individual noble gas atoms within a molecular network and determined the interactions with a ...
