Speaking without vocal cords, thanks to a new AI-assisted wearable device      (via sciencedaily.com)     Original source 

Bioengineers have invented a thin, flexible device that adheres to the neck and translates the muscle movements of the larynx into audible speech. The device is trained through machine learning to recognize which muscle movements correspond to which words. The self-powered technology could serve as a non-invasive tool for people who have lost the ability to speak due to vocal cord problems.

Even inactive smokers are densely colonized by microbial communities      (via sciencedaily.com)     Original source 

Everything is everywhere -- under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team is presently working to accurately quantify how much inorganic carbon can be bound in these environments.

The atlas of unburnable oil in the world      (via sciencedaily.com)     Original source 

In order to limit the increase in global average temperature to 1.5 C, it is essential to drastically reduce carbon dioxide emissions in the atmosphere. This would mean not exploiting most of the existing coal, conventional gas and oil energy resources in regions around the world, according to new research. The study presents the atlas of unburnable oil in the world, a world map designed with environmental and social criteria that warns which oil resources should not be exploited to meet the commitments of the Paris Agreement signed in 2015 to mitigate the effects of climate change.

New bioengineered protein design shows promise in fighting COVID-19      (via sciencedaily.com)     Original source 

A recent scientific breakthrough has emerged from the work of researchers aiming to combat SARS-CoV-2, the virus responsible for COVID-19. The study focuses on the design and development of a novel protein capable of binding to the spike proteins found on the surface of the coronavirus. The goal behind this innovative approach is twofold: first, to identify and recognize the virus for diagnostic purposes, and second, to hinder its ability to infect human cells.

Unique way to track carbon emissions in bodies of water      (via sciencedaily.com)     Original source 

Carbon dioxide emissions are not typically associated with water ways, like streams and rivers, but emerging research shows that water bodies play an important role in storing and releasing carbon dioxide. As many states look for cost-effective ways to mitigate climate change, scientists looked at a way to optimize CO2 sensors to better measure carbon dioxide emissions in lotic, or moving, bodies of water offering a new tool that can help provide valuable information for everything from land use to climate action plans.

AI for astrophysics: Algorithms help chart the origins of heavy elements      (via sciencedaily.com)     Original source 

The origin of heavy elements in our universe is theorized to be the result of neutron star collisions, which produce conditions hot and dense enough for free neutrons to merge with atomic nuclei and form new elements in a split-second window of time. Testing this theory and answering other astrophysical questions requires predictions for a vast range of masses of atomic nuclei. Scientists are using machine learning algorithms to successfully model the atomic masses of the entire nuclide chart -- the combination of all possible protons and neutrons that defines elements and their isotopes.
