| Supernovae twins open up new possibilities for precision cosmology Posted: 07 May 2021 06:39 AM PDT Cosmologists have found a way to double the accuracy of measuring distances to supernova explosions - one of their tried-and-true tools for studying the mysterious dark energy that is making the universe expand faster and faster. |
| Hologram experts can now create real-life images that move in the air Posted: 07 May 2021 06:37 AM PDT They may be tiny weapons, but a holography research group has figured out how to create lightsabers -- green for Yoda and red for Darth Vader, naturally -- with actual luminous beams rising from them. |
| Homing in on the smallest possible laser Posted: 06 May 2021 11:21 AM PDT Physicists have succeeded in generating an unusual quantum state in charge carrier complexes that are closely linked to light particles and located in ultrathin semiconductor sheets. This process produces light similar to that of a laser. The phenomenon could be used to create the smallest possible solid-state lasers. |
| Hydrogen instead of electrification? Potentials and risks for climate targets Posted: 06 May 2021 11:21 AM PDT Hydrogen-based fuels should primarily be used in sectors such as aviation or industrial processes that cannot be electrified, finds a team of researchers. Producing these fuels is too inefficient, costly and their availability too uncertain, to broadly replace fossil fuels for instance in cars or heating houses. For most sectors, directly using electricity for instance in battery electric cars or heat pumps makes more economic sense. |
| Trial demonstrates early AI-guided detection of heart disease in routine practice Posted: 06 May 2021 11:21 AM PDT Heart disease can take a number of forms, but some types of heart disease, such as asymptomatic low ejection fraction, can be hard to recognize, especially in the early stages when treatment would be most effective. |
| Posted: 06 May 2021 11:20 AM PDT Like conductors of a spooky symphony, researchers have 'entangled' two small mechanical drums and precisely measured their linked quantum properties. Entangled pairs like this might someday perform computations and transmit data in large-scale quantum networks. |
| Researchers speed identification of DNA regions that regulate gene expression Posted: 06 May 2021 09:58 AM PDT Scientists have developed a highly efficient method to address a major challenge in biology -- identifying the genetic 'switches' that regulate gene expression. |
| Research breakthrough in the fight against cancer Posted: 06 May 2021 09:57 AM PDT Researchers have engineered a nanoparticle that has the potential to revolutionize disease treatment, including for cancer. |
| Microalgae biofuels: Changing carbohydrates into lipids Posted: 06 May 2021 07:54 AM PDT Engineers have developed a technique to repartition carbon resources from carbohydrates to lipids in microalgae. It is hoped that this method can be applied to biofuel production. |
| Laser pulses with record-breaking intensity Posted: 06 May 2021 07:54 AM PDT Researchers have demonstrated a record-high laser pulse intensity of over 1023 W/cm2 using a petawatt laser. It took more than a decade to reach this laser intensity. These ultrahigh intensity light pulses will enable exploration of complex interactions between light and matter in ways not possible before. |
| T-GPS processes a graph with trillion edges on a single computer? Posted: 06 May 2021 07:54 AM PDT A research team has developed a new technology that enables to process a large-scale graph algorithm without storing the graph in the main memory or on disks. |
| Better way to determine safe drug doses for children Posted: 06 May 2021 07:53 AM PDT To make drugs and their development safer for children, researchers have developed a method that could help determine safe drug doses more quickly. In their study, the team created a model of how organs develop that is more data-driven and consequently less prone to bias. |
| New indicator for oxygen levels in early oceans developed Posted: 06 May 2021 07:53 AM PDT A geoscientific research team led by scientists from the University of Cologne has come a decisive step closer to determining the oxygen levels in the early Earth's history by analyzing the composition of tungsten isotopes. |
| Roadmap to expand NY solar energy, meet green goals Posted: 06 May 2021 07:53 AM PDT Solar-power developers need to explore using lower-quality agricultural land for solar energy, incentivize dual-use (combined agriculture and solar) options, avoid concentrated solar development and engage communities early to achieve New York's green energy goals, according to recent research. |
| Significant progress in lithium-air battery development Posted: 06 May 2021 07:48 AM PDT Researchers are making significant progress in the development of stable and practical electrolytes for lithium-oxygen batteries. |
| Cardiovascular disease could be diagnosed earlier with new glowing probe Posted: 05 May 2021 10:05 AM PDT Researchers have created a probe that glows when it detects an enzyme associated with issues that can lead to blood clots and strokes. |
| What is driving reductions in residential greenhouse gas emissions in the US? Posted: 05 May 2021 08:14 AM PDT A study finds smarter home construction and decarbonization of electric supply are contributing to lower emissions from individual households, but troubling trends show other factors could begin to cancel out this progress. |
