IMAGE: Two photons are entangled, one in polarization and the other in orbital angular momentum — twisted light. By passing the polarization photon through the fiber and keeping the twisted light… view more  Credit: Wits University New research done at the University of the Witwatersrand in Johannesburg, South Africa, and Huazhang University of Science and Technology

Researchers have developed an ultra-thin and ultra-flexible electronic material that could be printed and rolled out like newspaper, for the touchscreens of the future. The touch-responsive technology is 100 times thinner than existing touchscreen materials and so pliable it can be rolled up like a tube. To create the new conductive sheet, an RMIT University-led

IMAGE: A simple, modular chemical approach could produce over 65,000 different types of complex nanorods. Electron microscope images are shown for 32 of these nanorods, which form with various combinations of… view more  Credit: Schaak Laboratory, Penn State Using straightforward chemistry and a mix-and-match, modular strategy, researchers have developed a simple approach that could produce over

How would you go about returning books to the correct shelves in a large library with the least amount of walking? How would you determine the shortest route for a truck that has to deliver many packages to multiple cities? These are some examples of the “traveling salesman problem”, a type of “combinatorial optimization” problem,

Chad Mirkin, director of the International Institute for Nanotechnology at Northwestern University, is the winner of the 2020 Philip Hauge Abelson Prize, which is presented by the American Association for the Advancement of Science to a scientist or public servant who has contributed significantly to the advancement of science in the United States. “Uniquely, Chad

Sepsis claims one life every four seconds. It is the primary cause of death in hospitals, and one of the ten leading causes of death worldwide. Sepsis is associated with the body’s inflammatory response to a bacterial infection and progresses extremely rapidly: every hour that goes by before it is properly diagnosed and treated increases

Human skin is a fascinating and multifunctional organ with unique properties originating from its flexible and compliant nature. It allows for interfacing with external physical environment through numerous receptors interconnected with the nervous system. Scientists have been trying to transfer these features to artificial skin for a long time, aiming at robotic applications. Operation of

Fifty years ago, scientists hit upon what they thought could be the next rocket fuel. Carboranes — molecules composed of boron, carbon and hydrogen atoms clustered together in three-dimensional shapes — were seen as the possible basis for next-generation propellants due to their ability to release massive amounts of energy when burned. It was technology

Researchers have discovered a method to control biomolecular machines over a wide temperature range using deep-sea osmolyte trimethylamine N-oxide (TMAO). This finding could open a new dimension in the application of artificial machines fabricated from biomolecular motors and other proteins. Biomolecular motors are the smallest natural machines that keep living organisms dynamic. They can generate

Science An international team of researchers from ITMO University, the Australian National University, and Korea University have experimentally trapped an electromagnetic wave in a gallium arsenide nanoresonator a few hundred nanometers in size for a record-breaking

Rapid progress in the field of metallic nanotechnology is sparking a science revolution that is likely to impact all areas of society, according to professor of physics Ventsislav Valev and his team at the University of Bath in the UK. Metallic nanotechnology is an area that allows microscopic particles of metals, such as gold and
