| Skin in the game: Transformative approach uses the human body to recharge smartwatches Posted: 01 Jul 2021 04:52 PM PDT As smart watches are increasingly able to monitor the vital signs of health, including what's going on when we sleep, a problem has emerged: those wearable, wireless devices are often disconnected from our body overnight, being charged at the bedside. |
| Understanding potential topological quantum bits Posted: 01 Jul 2021 11:09 AM PDT Scientists have been looking for half an electron as a basis for a quantum computer. They investigated a promising experimental setup just to find that the signals they measured were not telling the truth. |
| Using AI to predict 3D printing processes Posted: 01 Jul 2021 11:09 AM PDT Metal additive manufacturing (AM) experiments are slow and expensive. Engineers are using physics-informed neural networks to predict the outcomes of complex processes involved in AM. The team trained the model on supercomputers using experimental and simulated data. They recreated the dynamics of two benchmark experiments in metal AM. The method could lead to fast prediction tools for AM in the future. |
| Novel microscopy method provides look into future of cell biology Posted: 01 Jul 2021 10:49 AM PDT What if a microscope allowed us to explore the 3D microcosm of blood vessels, nerves, and cancer cells instantaneously in virtual reality? What if it could provide views from multiple directions in real time without physically moving the specimen and worked up to 100 times faster than current technology? |
| New data science platform speeds up Python queries Posted: 01 Jul 2021 09:06 AM PDT Data queries written in Python, a commonly used programming language, can grind data analytics platforms to a crawl, but a new platform may finally solve the Python efficiency problem. |
| How children integrate information Posted: 01 Jul 2021 08:27 AM PDT Researchers use a computer model to explain how children integrate information during word learning. |
| Posted: 30 Jun 2021 01:37 PM PDT Researchers propose a scheme to identify and weigh the quantum orbits in strong-field tunneling ionization. |
| Machine learning helps in predicting when immunotherapy will be effective Posted: 30 Jun 2021 10:50 AM PDT Cancer cells can put the body's immune cells into sleep mode. Immunotherapy can reverse this, but it doesn't work for all patients and all cancer types. Researchers have now developed machine learning models that can predict if someone is likely to respond positively to immunotherapy. In clinical settings, this could pave the way for personalized immunotherapy approaches for patients, as well as guidance on how to best combine immunotherapy with other treatments. |
| Common errors in internet energy analysis Posted: 30 Jun 2021 09:54 AM PDT When it comes to understanding and predicting trends in energy use, the internet is a tough nut to crack. So say energy researchers in two recent articles that discuss the pitfalls that plague estimates of the internet's energy and carbon impacts. |
| Researchers look to human 'social sensors' to better predict elections and other trends Posted: 30 Jun 2021 08:54 AM PDT Researchers can gather highly accurate information about social trends and groups by asking about a person's social circle rather than interrogating their own individual beliefs. |
| New research lifts the clouds on land clearing and biodiversity loss Posted: 30 Jun 2021 08:54 AM PDT A new mathematical model has been developed to uncover land clearing when satellite imagery is obstructed by clouds. |
| Thinking in 3D improves mathematical skills Posted: 30 Jun 2021 08:53 AM PDT Spatial reasoning ability in small children reflects how well they will perform in mathematics later. Researchers recently came to this conclusion, making the case for better cultivation of spatial reasoning. |
| Technology only two atoms thick could enable storage of information in thinnest unit Posted: 30 Jun 2021 08:48 AM PDT The new technology, enabling the storage of information in the thinnest unit known to science, is expected to improve future electronic devices in terms of density, speed, and efficiency. The allowed quantum-mechanical electron tunneling through the atomically thin film may boost the information reading process much beyond current technologies. The technology involves laterally sliding one-atom-thick layers of boron and nitrogen one over the other -- a new way to switch electric polarization on/off. |
| Novel heat-management material keeps computers running cool Posted: 29 Jun 2021 04:17 PM PDT UCLA engineers have demonstrated successful integration of a novel semiconductor material into high-power computer chips to reduce heat on processors and improve their performance. The advance greatly increases energy efficiency in computers and enables heat removal beyond the best thermal-management devices currently available. |
