Pushing the bounds of vision could reveal hidden worlds

Nature is complex – often too complex for humans to see. But squint-controlled glasses that let people see 3-D thermal images and a camera that can capture the inner workings of high-speed chemical reactions are helping ...

Hot nanoparticles produce giant and explosive bubbles

When gold nano particles in water are illuminated by a laser, they get very hot: well above the boiling point of water. The formation of vapour bubbles caused by this, is well-known. New experiments, however, using a very ...

Low pressure reduces bubble trouble

Spray coating and inkjet-based electronics manufacture are among the industrial applications in which liquid droplets are applied to a surface. But minuscule air bubbles that get trapped beneath the droplet as it lands can ...

Plankton swim against the current

Zooplankton are often considered to be a passive source of food for fish and other aquatic animals. But at least one of their representatives, the millimetre-sized copepod (Eurytemora affinis), moves purposefully in turbulent ...

Do speed cameras really save lives?

Speed cameras have been the focus of motorists' anger and frustration for years, although we are told repeatedly that they are an effective means of reducing death and injury on the roads. But is this really the case?

New machine evaluates soybean at harvest for quality

When a field of soybeans is ready to harvest, speed is of the essence. But harvesting grinds to a halt every time the combine operator has to climb down out of the cab to manually check for quality—whole, un-split beans ...
