Artificial intelligence system rapidly predicts how two proteins will attach

Posted: 01 Feb 2022 01:56 PM PST

A new machine learning system can predict the structure formed when two proteins dock, in a process that's between 50 to 800 times faster than some software-based methods. This could help scientists better understand biological processes or speed the development of new therapies.

Climate change has likely begun to suffocate the world’s fisheries

Posted: 01 Feb 2022 01:10 PM PST

By 2080, around 70% of the world's oceans could be suffocating from a lack of oxygen as a result of climate change, potentially impacting marine ecosystems worldwide, according to a new study. The new models find mid-ocean depths that support many fisheries worldwide are already losing oxygen at unnatural rates and passed a critical threshold of oxygen loss in 2021.

Mighty powerful microbes: New insights into microbes that breathe rocks

Posted: 01 Feb 2022 11:39 AM PST

Microbes may be miniscule, but they have a massive impact on Earth and its habitability. They are uniquely different from animals, plants, and other eukaryotic organisms in that they can gain energy from 'breathing' a surprisingly wide range of surfaces and materials. Microbes also drastically re-shape their environment as they feast on these energy sources, making microbes major players in the cycling and availability of nutrients on Earth. One especially well-known example was the rise of oxygen on Earth due to the metabolism of photosynthetic bacteria.

How Omicron escapes from antibodies

Posted: 01 Feb 2022 11:39 AM PST

Dozens of mutations in the spike protein of the Omicron variant help it to evade all four of the classes of antibodies that can target SARS-CoV-2, according to a new study. This includes antibodies generated by the immune systems of vaccinated or previously infected people, as well as most of the monoclonal antibody treatments that have been developed.

New research examines how staple grains can be used as an effective food group for dietary shifts that can be culturally appropriate as well as environmentally sustainable.

Replacing animal agriculture and shifting to a plant-based diet could drastically curb greenhouse gas emissions, according to new model

Posted: 01 Feb 2022 11:39 AM PST

Phasing out animal agriculture represents 'our best and most immediate chance to reverse the trajectory of climate change,' according to a new model developed by scientists.

Expanding renewable energy need not hinder conservation efforts

A study has found that expanding green energy production sites in the future won't necessarily be a threat to protected areas of land.

Hepatitis E virus defies alcohol-based hand disinfectants

Posted: 01 Feb 2022 08:52 AM PST

The hepatitis E virus (HEV) can cause serious liver inflammation and is the most common cause of acute virus-mediated hepatitis worldwide. Infection can be prevented through appropriate hygiene measures. Scientists have investigated the effectiveness of various common hand disinfectants against HEV. They were able to show that most formulations do not completely inactivate the virus.

Study finds little genetic basis for some sea stars staying healthy amid deadly wasting syndrome

Posted: 01 Feb 2022 08:51 AM PST

Healthy-looking ochre sea stars have minimal genetic difference from those displaying symptoms of sea star wasting syndrome, say researchers who examined whether genetic variation was the reason some animals went unaffected during an epidemic of the deadly disease.
