| Printing flexible wearable electronics for smart device applications Posted: 10 Jun 2021 11:44 AM PDT With the increase in demand for flexible wearable electronics, researchers have explored flexible energy storage devices, such as flexible supercapacitators, that are lightweight and safe and easily integrate with other devices. Printing electronics has proved to be an economical, simple, and scalable strategy for fabricating FSCs. Researchers provide a review of printed FSCs in terms of ability to formulate functional inks, design printable electrodes, and integrate functions with other electronic devices. |
| Bacteria-sized robots take on microplastics and win by breaking them down Posted: 10 Jun 2021 10:57 AM PDT Small pieces of plastic are everywhere, stretching from urban environments to pristine wilderness. Left to their own devices, it can take hundreds of years for them to degrade completely. Catalysts activated by sunlight could speed up the process, but getting these compounds to interact with microplastics is difficult. In a proof-of-concept study, researchers developed self-propelled microrobots that can swim, attach to plastics and break them down. |
| Could all your digital photos be stored as DNA? Posted: 10 Jun 2021 10:57 AM PDT Biological engineers have demonstrated a way to easily retrieve data files stored as DNA. This could be a step toward using DNA archives to store enormous quantities of photos, images, and other digital content. |
| Microscopic imaging without a microscope? Posted: 10 Jun 2021 10:56 AM PDT A new technique uses high-throughput sequencing, instead of a microscope, to obtain ultra-high-resolution images of gene expression from a tissue slide. |
| Tuning the energy gap: A novel approach for organic semiconductors Posted: 10 Jun 2021 10:55 AM PDT What is already established for inorganic semiconductors stays a challenge for their organic counterparts: Tuning the energy gap by blending different semiconducting molecules to optimize device performance. Now, scientists demonstrated how to reach this goal. |
| Humans are ready to take advantage of benevolent AI Posted: 10 Jun 2021 10:55 AM PDT Humans expect that AI is benevolent and trustworthy. A new study reveals that at the same time humans are unwilling to cooperate and compromise with machines. They even exploit them. |
| Research uncovers broadband gaps in US to help close digital divide Posted: 10 Jun 2021 10:38 AM PDT Events of the past year have exposed the crisis of the digital divide in the U.S. To tackle this problem, researchers have developed a new tool to smooth the collection of federal broadband access data that helps pinpoint coverage gaps across the US. |
| Cloud computing expands brain sciences Posted: 10 Jun 2021 10:38 AM PDT People often think about human behavior in terms of what is happening in the present -- reading a newspaper, driving a car, or catching a football. But other dimensions of behavior extend over weeks, months, and years. |
| New twist on DNA data storage lets users preview stored files Posted: 10 Jun 2021 06:11 AM PDT Researchers have turned a longstanding challenge in DNA data storage into a tool, using it to offer users previews of stored data files -- such as thumbnail versions of image files. |
| Researchers create quantum microscope that can see the impossible Posted: 09 Jun 2021 08:55 AM PDT In a major scientific leap, researchers have created a quantum microscope that can reveal biological structures that would otherwise be impossible to see. |
| Important contribution to spintronics has received little consideration until now Posted: 09 Jun 2021 08:55 AM PDT The movement of electrons can have a significantly greater influence on spintronic effects than previously assumed. Until now, a calculation of these effects took, above all, the spin of electrons into consideration. The study offers a new approach in developing spintronic components. |
| Machine learning speeds up simulations in material science Posted: 09 Jun 2021 07:58 AM PDT Research, development, and production of novel materials depend heavily on the availability of fast and at the same time accurate simulation methods. Machine learning, in which artificial intelligence autonomously acquires and applies new knowledge, will soon enable researchers to develop complex material systems in a purely virtual environment. How does this work, which applications will benefit? |
| Physicists achieve significant improvement in spotting neutrinos in a cosmic haystack Posted: 09 Jun 2021 07:58 AM PDT Two articles describe how ground-breaking image reconstruction and analysis algorithms developed for surface-based MicroBooNE detector filter out cosmic ray tracks to pinpoint elusive neutrino interactions with unprecedented clarity. |
| 'PrivacyMic': For a smart speaker that doesn't eavesdrop Posted: 09 Jun 2021 05:47 AM PDT Microphones are perhaps the most common electronic sensor in the world, with an estimated 320 million listening for our commands in the world's smart speakers. The trouble is that they're capable of hearing everything else, too. |
| Researchers create intelligent electronic microsystems from 'green' material Posted: 08 Jun 2021 05:37 PM PDT A research team has created an electronic microsystem that can intelligently respond to information inputs without any external energy input, much like a self-autonomous living organism. The microsystem is constructed from a novel type of electronics that can process ultralow electronic signals and incorporates a device that can generate electricity 'out of thin air' from the ambient environment. |
| Lack of math education negatively affects adolescent brain and cognitive development Posted: 07 Jun 2021 01:11 PM PDT Adolescents who stopped studying math showed a reduction in a critical brain chemical for brain development. This reduction in brain chemical was found in a key brain area that supports math, memory, learning, reasoning and problem solving. |
| The role of computer voice in the future of speech-based human-computer interaction Posted: 01 Jun 2021 09:17 AM PDT Researchers have performed a meta-synthesis to understand how we perceive and interact with the voice (and the body) of various machines. Their findings have generated insights into human preferences, and can be used by engineers and designers to develop future vocal technologies. |
