Crystals for efficient refrigeration

Researchers at the Carnegie Institution have discovered a new efficient way to pump heat using crystals. The crystals can pump or extract heat, even on the nanoscale, so they could be used on computer chips to prevent overheating or even meltdown, which is currently a major limit to higher computer speeds.

Nanosensors for the real world

Over the last decade there has been an increased interest in developing resonators for gravitmetric sensing; however, the sensors' response to variations in temperature has prevented them from being used outside the laboratory. New sensors developed by researchers at the University of Cambridge negate the effects of temperature so that they may be used in industries including health care, telecommunications and environmental monitoring.

Nanotechnology helps to visualize latent fingerprints

Scientists have introduced a new method developed specifically for use on paper. It produces a 'negative' of the fingerprint and is, in contrast to conventional methods, independent of the composition of the sweat residue left behind.
