| Putting honeybee hives on solar parks could boost the value of UK agriculture Posted: 18 Oct 2021 02:22 PM PDT The value of UK agriculture could be boosted by millions of pounds a year if thousands of honeybee hives were deployed on solar parks across the country, a new study reveals. However, scientists caution that the benefits of managing solar parks for wild pollinators over honeybees should be prioritized where appropriate and should be assessed on a site by site basis. |
| Solar energy can be cheap and reliable across China by 2060 Posted: 18 Oct 2021 01:32 PM PDT How much will solar power really cost in China in the coming decades, including the challenges its inherent variability poses to the grid? Researchers have found that solar energy could provide 43.2% of China's electricity demands in 2060 at less than two-and-a-half U.S. cents per kilowatt-hour. |
| Breakthrough proof clears path for quantum AI Posted: 18 Oct 2021 12:42 PM PDT Convolutional neural networks running on quantum computers have generated significant buzz for their potential to analyze quantum data better than classical computers can. |
| Posted: 18 Oct 2021 10:03 AM PDT Engineers have built multi-legged robots capable of maneuvering in challenging environments and accomplishing difficult tasks collectively, mimicking their natural-world counterparts. |
| Uncovering the secrets of ultra-low frequency gravitational waves Posted: 18 Oct 2021 08:25 AM PDT New methods of detecting ultra-low frequency gravitational waves can be combined with other, less sensitive measurements to deliver fresh insights into the early development of our universe, according to researchers. |
| How the brain navigates cities Posted: 18 Oct 2021 08:25 AM PDT A study suggests our brains are not optimized to calculate the shortest possible route when navigating on foot. Instead, pedestrians use vector-based navigation, choosing 'pointiest' paths that point most directly toward their destination, even if the routes are longer. |
| Optimum pressure to improve the performance of lithium metal batteries Posted: 18 Oct 2021 08:25 AM PDT A team of materials scientists and chemists has determined the proper stack pressure that lithium metal batteries, or LMBs, need to be subjected to during battery operation in order to produce optimal performance. |
| Scientists discover method to boost energy generation from microalgae Posted: 18 Oct 2021 07:59 AM PDT The variety of humble algae that cover the surface of ponds and seas could hold the key to boosting the efficiency of artificial photosynthesis, allowing scientists to produce more energy and lower waste in the process. A study showed how encasing algae protein in liquid droplets can dramatically enhance the algae's light-harvesting and energy-conversion properties by up to three times. This energy is produced as the algae undergoes photosynthesis, which is the process used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy. When light hits the droplet, light waves travel around the curved edges of the droplet. Light is effectively trapped within the droplet for a longer period of time, giving more opportunity for photosynthesis to take place, hence generating more energy. |
