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.
Recent experiments have confirmed that a technique developed several years ago at the National Institute of Standards and Technology (NIST) can enable optical microscopes to measure the three-dimensional (3D) shape of objects at nanometer-scale resolution - far below the normal resolution limit for optical microscopy.
