| Interactive typeface for digital text Posted: 12 May 2021 11:35 AM PDT Researchers have developed a computer font that adapts its appearance based on the user's interaction with the text. ''AdaptiFont'' measures a user's reading speed and interactively changes the font's shape seamlessly and continuously to allow the user to read text more easily. By employing an artificial intelligence algorithm, new personalized fonts are generated on the fly in such a way that they increase an individual reader's reading speed. |
| A long-lasting, stable solid-state lithium battery Posted: 12 May 2021 08:56 AM PDT Researchers have designed a stable, lithium-metal solid state battery that can be charged and discharged at least 10,000 times -- far more cycles than have been previously demonstrated --- at a high current density. The battery technology could increase the lifetime of electric vehicles to that of the gasoline cars -- 10 to 15 years -- without the need to replace the battery. With its high current density, the battery could pave the way for electric vehicles that can fully charge within 10 to 20 minutes. |
| Engineered bacteria show promise for sustainable biofuel industry Posted: 12 May 2021 08:56 AM PDT Acetone, a volatile solvent used for everything from removing nail polish and cleaning textiles to manufacturing plastics, could get a sustainability boost from a new strain of engineered bacteria. |
| Scaling down Ionic Transistors to the ultimate limit Posted: 12 May 2021 08:55 AM PDT Researchers have developed an atomic-scale ion transistor based on electrically gated graphene channels of around 3 angstrom width which demonstrated highly selective ion transport. They also found that ions move a hundred times faster in such a tiny channel than they do in bulk water. This breakthrough leads to highly switchable ultrafast ion transport that can find important applications in electrochemical and biomedical applications. |
| Efficiently smuggling drugs into cells Posted: 12 May 2021 08:55 AM PDT A new method called Progressive Mechanoporation makes it possible to mechanically disrupt the membranes of cells for a short time period and let drugs or genes inside cells. In this way, researchers can test new therapies more easily than before. |
| Smaller chips open door to new RFID applications Posted: 12 May 2021 08:55 AM PDT Researchers have made what is believed to be the smallest state-of-the-art RFID chip, which should drive down the cost of RFID tags. In addition, the chip's design makes it possible to embed RFID tags into high value chips, such as computer chips, boosting supply chain security for high-end technologies. |
| An enzyme system for the hydrogen industry Posted: 12 May 2021 08:55 AM PDT An enzyme could make a dream come true for the energy industry: It can efficiently produce hydrogen using electricity and can also generate electricity from hydrogen. The enzyme is protected by embedding it in a polymer. |
| Brand new physics of superconducting metals refuted by physicists Posted: 12 May 2021 05:34 AM PDT Scientists have demonstrated that other physicists' recent 'discovery' of the field effect in superconductors is nothing but hot electrons after all. A team of scientists have found new and compelling evidence that the observation of the field effect in superconducting metals by another group can be explained by a simple mechanism involving the injection of the electrons, without the need for novel physics. |
| Gold leaf could help diagnose viral infections in low-resource settings Posted: 12 May 2021 05:34 AM PDT Gold leaf -- gold metal hammered into thin sheets -- is used by artists and crafters to gild picture frames, artwork and clothing. Despite its luxurious appearance, the material is affordable and available at most craft stores. Now, researchers have developed gold leaf electrodes that, in combination with a CRISPR-based assay, could sensitively detect human papillomavirus (HPV) DNA in human samples. The method also could be modified to diagnose other viral infections. |
| Harnessing the hum of fluorescent lights for more efficient computing Posted: 12 May 2021 05:34 AM PDT The property that makes fluorescent lights buzz could power a new generation of more efficient computing devices that store data with magnetic fields, rather than electricity. |
| How to thermally cloak an object Posted: 11 May 2021 05:11 PM PDT Can you feel the heat? To a thermal camera, which measures infrared radiation, the heat that we can feel is visible, like the heat of a traveler in an airport with a fever or the cold of a leaky window or door in the winter. Researchers report a theoretical way of mimicking thermal objects or making objects invisible to thermal measurements. |
| Tiny, wireless, injectable chips use ultrasound to monitor body processes Posted: 11 May 2021 02:41 PM PDT Researchers report that they have built what they say is the world's smallest single-chip system, consuming a total volume of less than 0.1 mm3. The system is as small as a dust mite and visible only under a microscope. In order to achieve this, the team used ultrasound to both power and communicate with the device wirelessly. |
| Engine converts random jiggling of microscopic particle into stored energy Posted: 11 May 2021 01:07 PM PDT Researchers have designed a remarkably fast engine that taps into a new kind of fuel -- information. This engine converts the random jiggling of a microscopic particle into stored energy. It could lead to significant advances in the speed and cost of computers and bio-nanotechnologies. |
| Bone-deep: Mineral found in human bone can help fight toxic organic compounds Posted: 11 May 2021 09:38 AM PDT Many industrial processes emit volatile organic compounds (VOCs) that are hazardous to human health. In a new study, scientists tailor the catalytic activity of hydroxyapatite, a mineral contained in human bones, using mechanical stress. This method was inexpensive and resulted in a 100% VOC conversion. |
| Lasers, levitation and machine learning make better heat-resistant materials Posted: 11 May 2021 09:37 AM PDT Scientists across several disciplines have combined forces to create a new process for testing and predicting the effects of high temperatures on refractory oxides. |
| 'Safe System' approach could dramatically reduce road deaths while improving equity Posted: 11 May 2021 09:37 AM PDT A new approach to road safety that relies on design and engineering principles -- the 'Safe System' approach -- could lead to dramatic reductions in vehicle-related deaths and injuries if implemented in the US. |
| Simulating sneezes and coughs to show how COVID-19 spreads Posted: 11 May 2021 09:37 AM PDT Researchers have published papers on the droplets of liquid sprayed by coughs or sneezes and how far they can travel under different conditions. Their findings reinforce the importance of wearing masks, maintaining social distancing, avoiding poorly ventilated indoor spaces and washing your hands frequently, especially with the emergence of new, more transmissible variants of SARS-CoV-2, the virus that causes COVID-19. |
| Box fan air cleaner can greatly reduce virus transmission, study finds Posted: 11 May 2021 09:36 AM PDT A systematic modeling study of simple air cleaners using a box fan shows these inexpensive units can greatly decrease the amount of airborne virus in these spaces, if used appropriately. |
