| 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. |
| Physicists observationally confirm Hawking's black hole theorem for the first time Posted: 01 Jul 2021 08:27 AM PDT Physicists have used gravitational waves to observationally confirm Hawking's black hole theorem. |
| Instant water cleaning method 'millions of times' better than commercial approach Posted: 01 Jul 2021 08:26 AM PDT A water disinfectant created on the spot using just hydrogen and the air around us is millions of times more effective at killing viruses and bacteria than traditional commercial methods, according to scientists. |
| Posted: 30 Jun 2021 01:37 PM PDT Researchers propose a scheme to identify and weigh the quantum orbits in strong-field tunneling ionization. |
| Astronauts demonstrate CRISPR/Cas9 genome editing in space Posted: 30 Jun 2021 11:16 AM PDT Researchers have developed and successfully demonstrated a novel method for studying how cells repair damaged DNA in space. |
| Variations in quantitative MRI scanners' measurements Posted: 30 Jun 2021 11:16 AM PDT Magnetic resonance imaging (MRI) is widely used in medicine to detect, diagnose and treat diseases such as cancer, while relying on experts' interpretation of images. Quantitative MRI, which obtains numerical measurements during the scans, can now potentially offer greater accuracy, repeatability and speed -- but rigorous quality control is needed for it to reach its full potential, according to a new study. |
| 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. |
| 'Plugging in' to produce environmentally friendly bioplastics Posted: 30 Jun 2021 09:54 AM PDT Bioplastics -- biodegradable plastics made from biological substances rather than petroleum -- can be created in a more economical and environmentally friendly way from the byproducts of corn stubble, grasses and mesquite agricultural production, according to a new study. |
| Human stem cells enable model to test drug impact on brain's blood barrier Posted: 30 Jun 2021 09:54 AM PDT Using an experimental model to simulate the blood-brain barrier, scientists reported in unprecedented detail how antioxidants protect the brain from inflammation caused by such neurodegenerative diseases as Alzheimer's and Parkinson's. |
| 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. |
| NIST laser 'comb' systems now measure all primary greenhouse gases in the air Posted: 30 Jun 2021 08:54 AM PDT Researchers at NIST have upgraded their laser frequency-comb instrument to simultaneously measure three airborne greenhouse gases -- nitrous oxide, carbon dioxide and water vapor -- plus the major air pollutants ozone and carbon monoxide. |
| Better method to predict offshore wind power Posted: 30 Jun 2021 08:54 AM PDT Researchers have developed a machine learning model using a physics-based simulator and real-world meteorological data to better predict offshore wind power. |
| Mixing it up: A low-cost way to make efficient, stable perovskite solar cells Posted: 30 Jun 2021 08:54 AM PDT By using a fluid mixing process instead of expensive, high-temperature fabrication methods, researchers may have demonstrated a pathway to producing flexible, printed solar cells on a cost effective, industrial scale. |
| 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. |
| Want new advanced materials? There's a phase transition for that Posted: 30 Jun 2021 08:53 AM PDT Researchers experimentally confirmed three previously unknown phase transition phenomena in soft colloidal crystals. Knowledge of such phenomena will be useful for imparting new properties to materials without altering their chemical composition. |
| Astronomers have identified a white dwarf so massive that it might collapse Posted: 30 Jun 2021 08:53 AM PDT Astronomers have identified an extremely magnetized and rapidly rotating ultra-massive white dwarf. Several telescopes characterized the dead star. |
| 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. |
| Scientists intensify electrolysis, utilize carbon dioxide more efficiently with magnets Posted: 30 Jun 2021 06:13 AM PDT A promising approach captures atmospheric carbon dioxide and then through CO2 electrolysis converts it into value-added chemicals and intermediates, like ethanol. Reducing the energy consumption of this high-power process has been underexplored. Researchers report a new opportunity to use magnetism to reduce the energy required for CO2 electrolysis by up to 60% in a flow electrolyzer. |
| Turning plastic into foam to combat pollution Posted: 29 Jun 2021 01:13 PM PDT Researchers have developed a method to turn biodegradable plastic knives, spoons, and forks into a foam that can be used as insulation in walls or in flotation devices. The investigators placed the cutlery into a chamber filled with carbon dioxide. As pressure increased, the gas dissolved into the plastic. When they suddenly released the pressure in the chamber, the carbon dioxide expanded within the plastic, creating foaming. |
| Polymers in meteorites provide clues to early solar system Posted: 29 Jun 2021 09:08 AM PDT Meteorites that do not experience high temperatures at any point in their existence provide a good record of complex chemistry present when or before our solar system was formed. So researchers have examined individual amino acids in these meteorites, many of which are not in present-day organisms. Researchers now show the existence of a systematic group of amino acid polymers across several members of the oldest meteorite class, the CV3 type. |
| Mouse brain imaged from the microscopic to the macroscopic level Posted: 28 Jun 2021 02:05 PM PDT Researchers have leveraged existing advanced X-ray microscopy techniques to bridge the gap between MRI (magnetic resonance imaging) and electron microscopy imaging, providing a viable pipeline for multiscale whole brain imaging within the same brain. |
