Researchers have developed a synthetic virus. This can be used in the future to 'package' new generations of medicines consisting of large biomolecules and to deliver them into diseased cells, by a natural process.
A new high-tech membrane is made of high-quality steel and is more stable and more flexible than conventional filters, also more environmentally-compatible because only inert gas and electrical power are needed for its manufacture.
Silicon has been the most successful material of the 20th century, with major global industries and even a valley named after it. But silicon may be running out of steam for high performance/low power electronics. As silicon strains against the physical limits of performance, could a material like InGaAs provide enough of an improvement over silicon that it would be worth the expense in new equipment lines and training to make the switch worthwhile?
A new research platform uses a laser to measure the nanomechanical properties of tiny structures undergoing stress and heating, an approach likely to yield insights to improve designs for microelectronics and batteries.
