Mathematical framework turns any sheet of material into any shape using kirigami cuts Posted: 20 Aug 2019 01:46 PM PDT Researchers have developed a mathematical framework that can turn any sheet of material into any prescribed shape, inspired by the paper craft termed kirigami (from the Japanese, kiri, meaning to cut and kami, meaning paper). |
New rechargeable aqueous battery challenges Lithium-ion dominance Posted: 20 Aug 2019 12:42 PM PDT A new rechargeable high voltage manganese dioxide zinc battery exceeds the 2 V barrier in aqueous zinc chemistry. With a voltage of 2.45-2.8V, the alkaline MnO2|Zn battery could break the long dominance of flammable and expensive lithium (Li)-ion batteries in the market. |
New tools to minimize risks in shared, augmented-reality environments Posted: 20 Aug 2019 12:29 PM PDT Security researchers have created ShareAR, a toolkit that lets developers build collaborative and interactive features into AR apps without sacrificing their users' privacy and security. |
Physicists use light flashes to discover, control new quantum states of matter Posted: 20 Aug 2019 10:47 AM PDT Scientists are developing new tools and techniques to access new states of matter hidden within superconducting and other complex materials. Harnessing these exotic states and their unique properties could lead to better computing, communicating and data storing technologies. |
Robust molecular propeller for unidirectional rotations created Posted: 20 Aug 2019 10:47 AM PDT A team of scientists has developed a molecular propeller that enables unidirectional rotations on a material surface when energized. |
A new way to 'hoard' resources in nano-sized factories targeted for biotech Posted: 20 Aug 2019 10:47 AM PDT Scientists have created a synthetic nano-sized factory, based on natural ones found in bacteria. This research could someday lead to new medical, industrial or bioenergy applications. |
Enabling longer space missions Posted: 20 Aug 2019 10:09 AM PDT The Hall thruster is a propulsion system that is often used by spacecraft engaged in longer missions. A recent study has shown how the operating lives of these systems can be further extended. |
Cost-effective fuel cell technology Posted: 20 Aug 2019 10:09 AM PDT Researchers have identified ammonia as a source for engineering fuel cells that can provide a cheap and powerful source for fueling cars, trucks and buses with a reduced carbon footprint. |
Stone Age boat building site has been discovered underwater Posted: 20 Aug 2019 10:09 AM PDT Researchers have discovered a new 8,000 year old structure 11 meters below sea level on the Isle of Wight. It is the most intact, wooden Middle Stone Age structure ever found in the UK. |
Shedding light on the reaction mechanism of PUVA light therapy for skin diseases Posted: 20 Aug 2019 10:09 AM PDT Physical chemists have clarified which chemical reactions take place during PUVA therapy. The therapy involves light-induced damage to the DNA of diseased cells. |
Lab-on-a-chip drives search for new drugs to prevent blood clots Posted: 20 Aug 2019 07:16 AM PDT The effectiveness of current anti-clotting medication can be limited due to the risk of complications. This is driving a need for alternatives that can both prevent the formation of blood clots and reduce the risk of excessive and life-threatening bleeding. A new biocompatible lab-on-a-chip could help accelerate the discovery and development of new anti-clotting therapies, with automated processes that can achieve in a few minutes what could take days in a full-sized lab. |
New protein spin labelling technique Posted: 20 Aug 2019 07:14 AM PDT Researchers develop a new site-directed spin labeling approach based on genetically encoded noncanonical amino acids amenable to Diels-Alder chemistry as well as a new spin label, PaNDA. |
A battery-free sensor for underwater exploration Posted: 20 Aug 2019 07:14 AM PDT Researchers have developed a battery-free underwater communication system that uses near-zero power to transmit sensor data. The system could be used to monitor sea temperatures to study climate change and track marine life over long periods -- and even sample waters on distant planets. |
Mini kidneys grown from stem cells give new insights into kidney disease and therapies Posted: 20 Aug 2019 07:14 AM PDT Medical researchers have grown 'miniature kidneys' in the laboratory that could be used to better understand how kidney diseases develop in individual patients. These kidney organoids were grown outside the body from skin cells derived from a single patient who has polycystic kidney disease. This method has paved the way for tailoring treatment plans specific to each patient, which could be extended to a range of kidney diseases. |
World's thinnest, lightest signal amplifier enables bioinstrumentation with reduced noise Posted: 20 Aug 2019 07:14 AM PDT A research group succeeded in developing the world's thinnest and lightest differential amplifier for bioinstrumentation. |
Lighting up proteins with Immuno-SABER Posted: 19 Aug 2019 02:57 PM PDT Researchers have developed a new DNA-nanotechnology-based approach called Immuno-SABER, that combines the protein targeting specificity of commonly available antibodies with a DNA-based signal-amplification strategy that enables the highly multiplexed visualization of many proteins in the same sample with pre-programmable and tunable fluorescence signals at each target site. |
Wired for sound: A third wave emerges in integrated circuits Posted: 19 Aug 2019 08:27 AM PDT A research renaissance into chip-based control of light-sound interactions could transform our 5G networks, satellite communications and defence industries. These interactions, known as Brillouin scattering, are set to underpin new designs in microchips and push our theoretical understanding of fundamental science. |
