| Graphene key for novel hardware security Posted: 10 May 2021 02:19 PM PDT As more private data is stored and shared digitally, researchers are exploring new ways to protect data against attacks from bad actors. Current silicon technology exploits microscopic differences between computing components to create secure keys, but artificial intelligence (AI) techniques can be used to predict these keys and gain access to data. Now, researchers have designed a way to make the encrypted keys harder to crack. |
| 'Flipping' optical wavefront eliminates distortions in multimode fibers Posted: 10 May 2021 01:15 PM PDT Researchers have devised a novel technique to 'flip' the optical wavefront of an image for both polarizations simultaneously, so that it can be transmitted through a multimode fiber without distortion. |
| Stimulators could aid spinal cord, heart therapies Posted: 10 May 2021 01:14 PM PDT Engineers develop a new version of their wireless implant that allows for multiple stimulators to be programmed and magnetically powered from a single transmitter outside the body. The implants could be used to treat spinal cord injuries or as pacemakers. |
| Geoscientists find that shallow wastewater injection drives deep earthquakes in Texas Posted: 10 May 2021 01:14 PM PDT Geoscientists have found that shallow wastewater injection -- not deep wastewater injections -- can drive widespread deep earthquake activity in unconventional oil and gas production fields. |
| Integrating medical imaging and cancer biology with deep neural networks Posted: 10 May 2021 11:39 AM PDT Scientists have carried out a study investigating whether deep neural networks can represent associations between gene expression, histology, and CT-derived image features. They found that the network could not only reproduce previously reported associations but also identify new ones. |
| 'Unmaking' a move: Correcting motion blur in single-photon images Posted: 10 May 2021 10:31 AM PDT Single-photon imaging is the future of high-speed digital photography and vastly surpasses conventional cameras in low-light conditions. However, fixing the blurring caused by the motion of independent objects remains challenging. Recently, researchers at developed an innovative de-blurring approach that accurately estimates the motion of individual objects and adjusts the final image accordingly. Their strategy produces high-quality images even in complex dynamic scenes and may find applications in medicine, science, and security. |
| 3D printing lays the foundation for a new range of diagnostic tests Posted: 10 May 2021 08:35 AM PDT Researchers have developed a 3D printing technique that extends the possibilities of lateral flow testing. These tests are widespread in the form of the classic pregnancy test and the COVID-19 self-tests. With the new printing technique, advanced diagnostic tests can be produced that are quick, cheap, and easy to use. |
| Light emitters for quantum circuits Posted: 10 May 2021 07:44 AM PDT The promise of a quantum internet depends on the complexities of harnessing light to transmit quantum information over fiber optic networks. A potential step forward was reported today by researchers who developed integrated chips that can generate light particles on demand and without the need for extreme refrigeration. |
| This system helps robots better navigate emergency rooms Posted: 10 May 2021 07:43 AM PDT Computer scientists have developed a more accurate navigation system that will allow robots to better negotiate busy clinical environments in general and emergency departments more specifically. The researchers have also developed a dataset of open source videos to help train robotic navigation systems in the future. |
| Engineering diseased human skin in vitro Posted: 10 May 2021 07:43 AM PDT A research team develops an artificial diabetic skin based on 3D cell printing. |
| Firefighting chemical found in sea lion and fur seal pups Posted: 10 May 2021 07:43 AM PDT A chemical that the New South Wales government has recently partially banned in firefighting has been found in the pups of endangered Australian sea lions and in Australian fur seals. The finding represents another possible blow to Australian sea lions' survival. Hookworm and tuberculosis already threaten their small and diminishing population, which has fallen by more than 60 percent over four decades. |
| Chill out: Advanced solar tech runs cooler and lasts longer Posted: 10 May 2021 07:43 AM PDT New mechanisms for converting sunlight to electricity more efficiently are also beneficial for extending the lifespan of solar panels. |
| Universal equation for explosive phenomena Posted: 10 May 2021 07:43 AM PDT Climate change, a pandemic or the coordinated activity of neurons in the brain: In all of these examples, a transition takes place at a certain point from the base state to a new state. Researchers have discovered a universal mathematical structure at these so-called tipping points. It creates the basis for a better understanding of the behavior of networked systems. |
| Intersection of 2D materials results in entirely New materials Posted: 10 May 2021 05:58 AM PDT Physics researchers discover that assembling 2D materials into a 3D arrangement does not just result in 'thicker' 2D materials but instead produces entirely new materials. The nanomesh technologically is simple to produce and offers tunable material properties to meet the demands of future applications. The team's next goal is to use the nanomesh on Silicon (Si) waveguides to develop quantum optical communications. |
| Wastewater treatment system recovers electricity, filters water Posted: 10 May 2021 05:56 AM PDT A new process uses bacteria to filter wastewater while creating electricity. |
| Why hotter clocks are more accurate Posted: 07 May 2021 11:05 AM PDT A new experiment shows that the more energy consumed by a clock, the more accurate its timekeeping. This is the first time that a measurement has been made of the entropy -- or heat loss -- generated by a minimal clock tens of nanometers thick and 1.5 millimeters long. Understanding the thermodynamic cost involved in timekeeping is a central step along the way in the development of future technologies, as systems approach the quantum realm. |
| Unusual semimetal shows evidence of unique surface conduction states Posted: 06 May 2021 07:55 AM PDT Scientists experimentally verify the existence of exotic surface conduction states in topological semimetals (TSMs), materials that lie at the boundary between conductors and insulators, by performing voltage scans of these surface states on a thin film sample of a TSM. The findings can pave the way for future study and exploitation of such conduction states in realizing novel, quantum transport phenomena. |
| Robotic flexing: Biologically inspired artificial muscles made from motor proteins Posted: 05 May 2021 07:20 AM PDT Scientists have devised a biologically inspired strategy to produce artificial muscle that self-assembles from motor proteins. Their approach, compatible with modern 3D printing, paves the way for printable robots that further resemble living creatures. |
