| Robots use fear to fight invasive fish Posted: 16 Dec 2021 11:59 AM PST The invasive mosquitofish (Gambusia holbrooki) chews off the tails of freshwater fishes and tadpoles, leaving the native animals to perish while dining on other fishes' and amphibians' eggs. Researchers engineered a robot to scare mosquitofish away, revealing how fear alters its behavior, physiology, fertility -- and may help turn the tide against invasive species. |
| Artificial intelligence accurately predicts who will develop dementia in two years Posted: 16 Dec 2021 11:59 AM PST Artificial intelligence can predict which people who attend memory clinics will develop dementia within two years with 92 per cent accuracy, a largescale new study has concluded. Using data from more than 15,300 patients in the US, researchers found that a form of artificial intelligence called machine learning can accurately tell who will go on to develop dementia. |
| A quantum view of 'combs' of light Posted: 16 Dec 2021 11:59 AM PST Frequency microcombs are specialized light sources that can function as light-based clocks, rulers and sensors to measure time, distance and molecular composition with high precision. New research presents a novel tool for investigating the quantum characteristics of these sources. |
| A robotic hand with a gecko-inspired grip Posted: 15 Dec 2021 05:40 PM PST Aiming to create a robotic gripper that can grasp with delicate strength, researchers combine adhesives based on gecko toes with a customized robotic hand. |
| Posted: 15 Dec 2021 05:40 PM PST Researchers developed a new, faster, less expensive method for screening billions of chemical compounds to find new, targeted drug therapies. |
| A mathematical model may give more efficient climate talks Posted: 15 Dec 2021 11:20 AM PST Achieving consensus among countries in global climate negotiations is a long and complicated process. Researchers have developed a mathematical model that describes the achievement of the 2015 Paris Agreement and that may contribute to more efficient negotiations when striving for unanimity. |
| Soft semiconductors that stretch like human skin can detect ultra-low light levels Posted: 15 Dec 2021 11:20 AM PST Researchers have demonstrated a new photodetector material that acts like a second skin layer and is up to 200% more stretchable than its original dimension without significantly losing its electric current. The researchers say the soft flexible photodetectors could enhance the utility of medical wearable sensors and implantable devices, among other applications. |
