New research shows that circadian clocks in some creatures can be described with a model that is based on the optimization of two trade-off properties: the "regularity" to keep time precisely, and the "entrainability" or flexibility to adjust the internal time to synchronize...
Quantum computing, secure wireless communication and advances in quantum teleportation could be closer to reality now that a team of researchers has developed a more efficient way of measuring wave functions that describe the strange behavior of these subatomic particles....
Honeycomb lattices and fractal structures are found in a range of biological materials. Now, scientists in the U.S., the U.K. and France have combined the two types of pattern to create a strong and lightweight material that could be used in a range of applications, from...
A new method of soft-tissue imaging could allow doctors to monitor respiratory treatments of cystic-fibrosis patients, reports an international research team. The technique – which measures the refraction of a grid pattern of X-rays passing through the lungs –...
Kevlar can fend off bullets traveling at hundreds of meters per second, but the supertough synthetic fiber is no match for debris hurtling through outer space at several kilometers per second.
For tiny fractions of a second, quartz glass can take on metallic properties, when it is illuminated be a laser pulse. The effect could be used to build logical switches much faster than today’s microelectronics. Read the associated Physical Review Letters abstract.
