| New optical hydrogen sensors eliminate risk of sparking Posted: 29 Apr 2021 09:34 AM PDT A new study documents an inexpensive, spark-free, optical-based hydrogen sensor that is more sensitive -- and faster -- than previous models. |
| Wearable glucose monitors shed light on progression of Type 2 diabetes in Hispanic adults Posted: 29 Apr 2021 09:34 AM PDT Researchers have shown wearable devices that continuously monitor blood sugar provide new insights into the progression of Type 2 diabetes among at-risk Hispanic/Latino adults. |
| High vaccination rate is key to future course of COVID-19 pandemic, computer modeling shows Posted: 29 Apr 2021 09:33 AM PDT Data scientists who developed highly accurate computer modeling to predict trends for COVID-19 cases nationwide have new research that shows how important a high rate of vaccination is to reducing case numbers and controlling the pandemic. |
| New law of physics helps humans and robots grasp the friction of touch Posted: 29 Apr 2021 09:33 AM PDT Although robotic devices are used in everything from assembly lines to medicine, engineers have a hard time accounting for the friction that occurs when those robots grip objects - particularly in wet environments. Researchers have now discovered a new law of physics that accounts for this type of friction, which should advance a wide range of robotic technologies. |
| Finding the optimal way to repay student debt Posted: 29 Apr 2021 09:33 AM PDT Though legislative reform is necessary to combat the growing burden of student loan debt in the U.S. on a grand scale, individual borrowers can take steps to repay their loans with as low long-term costs as possible. A new mathematical model develops a strategy for minimizing the overall cost of repaying student loans. |
| Machine learning algorithm helps unravel the physics underlying quantum systems Posted: 29 Apr 2021 08:24 AM PDT Scientists have developed an algorithm that provides valuable insights into the physics underlying quantum systems - paving the way for significant advances in quantum computation and sensing, and potentially turning a new page in scientific investigation. |
| Small generator captures heat given off by skin to power wearable devices Posted: 29 Apr 2021 08:22 AM PDT Scientists have developed a small, flexible device that can convert heat emitted from human skin to electrical power. In their research the team showed that the device could power an LED light in real time when worn on a wristband. The findings suggest that body temperature could someday power wearable electronics such as fitness trackers. |
| Research advances emerging DNA sequencing technology Posted: 29 Apr 2021 07:49 AM PDT Researchers have moved closer toward this goal by developing a nanopore sequencing platform that, for the first time, can detect the presence of nucleobases, the building blocks of DNA and RNA. |
| Blueprint for a robust quantum future Posted: 29 Apr 2021 07:49 AM PDT Researchers have established an invaluable resource for those looking to discover new quantum systems. |
| Battery parts can be recycled without crushing or melting Posted: 29 Apr 2021 06:51 AM PDT Researchers have now discovered that electrodes in lithium batteries containing cobalt can be reused as is after being newly saturated with lithium. In comparison to traditional recycling, which typically extracts metals from crushed batteries by melting or dissolving them, the new process saves valuable raw materials, and likely also energy. |
| Posted: 28 Apr 2021 08:37 AM PDT How acidic is a surface? Up until now, only average values could be determined. But in order to understand the chemical behavior of a surface, it is important to know how individual atoms in the surface might react. A new microscopy technique can now answer this question. |
| Researchers find how tiny plastics slip through the environment Posted: 28 Apr 2021 05:09 AM PDT Researchers found that a silica surface such as sand has little effect on slowing down the movement of the plastics, but that natural organic matter resulting from decomposition of plant and animal remains can either temporarily or permanently trap the nanoscale plastic particles, depending on the type of plastics. The work could lead to the development of better ways to filter out and clean up pervasive plastics from the environment. |
