Comet Catalina suggests comets delivered carbon to rocky planets Posted: 05 Mar 2021 10:37 AM PST Comet Catalina is helping explain more about our own origins as it becomes apparent that comets like Catalina could have been an essential source of carbon on planets like Earth and Mars during the early formation of the solar system.

Life's rich pattern: Researchers use sound to shape the future of printing Posted: 05 Mar 2021 08:35 AM PST Researchers have developed a way to coax microscopic particles and droplets into precise patterns by harnessing the power of sound in air. The implications for printing, especially in the fields of medicine and electronics, are far-reaching.

Beauty is in the brain: AI reads brain data, generates personally attractive images Posted: 05 Mar 2021 05:01 AM PST Researchers have succeeded in making an AI understand our subjective notions of what makes faces attractive. The device demonstrated this knowledge by its ability to create new portraits on its own that were tailored to be found personally attractive to individuals. The results can be utilized, for example, in modelling preferences and decision-making as well as potentially identifying unconscious attitudes.

This frog has lungs that act like noise-canceling headphones Posted: 04 Mar 2021 11:54 AM PST To succeed in mating, many male frogs sit in one place and call to their potential mates. But how do females pinpoint a perfect mate among all the background noise of other frogs? Now, researchers have found that they do it thanks to a set of lungs that reduce their eardrum's sensitivity to environmental noise, making it easier to zero in on the calls of males.

Ultralight materials: High strength through hierarchy Posted: 04 Mar 2021 11:54 AM PST As light as possible and as strong as possible at the same time. These are the requirements for modern lightweight materials, such as those used in aircraft construction and the automotive industry. A research team has now developed a new materials' design approach for future ultralight materials: Nanometer-sized metal struts that form nested networks on separate hierarchical levels provide amazing strength.

The (robotic) doctor will see you now Posted: 04 Mar 2021 08:24 AM PST A large majority of patients interacting with a health care provider via a video screen mounted on a robot said it was similar to an in-person interaction with a health care worker.

Tiny computers reveal how wild bats hunt so efficiently Posted: 03 Mar 2021 11:25 AM PST An international research team has experienced the world of wild bats to experience through echoes recorded on-board the bats by 3-gram computers. The tiny computers also recorded the echolocation calls and the movement of each bat in three dimensions. With surprising results: The bats control the strength of their returning echoes by calling louder or weaker - and when hunting, they merely whisper to focus only on the prey and reduce the clutter from other echoes.
