Nanoscale fluid-phase changes revealed

Millions of barrels of oil are produced daily from shale reservoirs, yet a significant amount remains untouched, trapped in molecular-sized pores on a nanoscale. Current reservoir models can't predict oil behavior or recovery ...

Unprecedented videos show RNA switching 'on' and 'off'

Similar to a light switch, RNA switches (called riboswitches) determine which genes turn "on" and "off." Although this may seem like a simple process, the inner workings of these switches have confounded biologists for decades.

'See through soil' could help farmers deal with future droughts

In research that may eventually help crops survive drought, scientists at Princeton University have uncovered a key reason that mixing material called hydrogels with soil has sometimes proven disappointing for farmers.

A mere ball, a very real mathematical challenge

To what extent could we predict the number on which a roulette ball is going to fall? Philippe Paccaud, micro-technology student, tackled this complex issue in his master's thesis. In the end, there was no miracle equation, ...
