Researchers teaching artificial intelligence about frustration in protein folding      (via sciencedaily.com)     Original source 

Scientists have found a new way to predict how proteins change their shape when they function, which is important for understanding how they work in living systems. While recent artificial intelligence (AI) technology has made it possible to predict what proteins look like in their resting state, figuring out how they move is still challenging because there is not enough direct data from experiments on protein motions to train the neural networks.

Humpbacks are among animals who manufacture and wield tools      (via sciencedaily.com)     Original source 

Researchers suggest a new designation of the humpback whales they study: tool wielders. Researchers have known that humpback whales create "bubble-nets" to hunt, but they have learned that the animals don't just create the bubble-nets; they manipulate this unique tool in a variety of ways to maximize their food intake in Alaskan feeding grounds.

Incorporating humidity improves estimations of climate impacts on health      (via sciencedaily.com)     Original source 

Governments, medical institutions and other bodies require accurate models on health-related matters in order to better organize their activities. Climate change has measurable impacts on society, including on human mortality. However, current models to assess the health impacts of climate change do not account for every environmental parameter, especially humidity, which could influence heat stress perceived by the human body, leaving room for improvement. Researchers have now incorporated humidity data from hundreds of cities into so-called heat stress indicators (HSIs) and assessed their performances in predicting heat-related deaths.

How early-life antibiotics turn immunity into allergy      (via sciencedaily.com)     Original source 

Researchers have shown how and why the depletion of microbes in a newborn's gut by antibiotics can lead to lifelong respiratory allergies. The research team identified a specific cascade of events that lead to allergies and asthma, opening many new avenues for exploring potential preventions and treatments.

'Molecular compass' points way to reduction of animal testing      (via sciencedaily.com)     Original source 

Machine learning models have become increasingly popular for risk assessment of chemical compounds. However, they are often considered 'black boxes' due to their lack of transparency. To increase confidence in these models, researchers proposed carefully identifying the areas of chemical space where these models are weak. They developed an innovative software tool for this purpose, and the results of this research approach have just been published.

Scientists discover new code governing gene activity      (via sciencedaily.com)     Original source 

A newly discovered code within DNA -- coined 'spatial grammar' -- holds a key to understanding how gene activity is encoded in the human genome. This breakthrough finding revealed a long-postulated hidden spatial grammar embedded in DNA. The research could reshape scientists' understanding of gene regulation and how genetic variations may influence gene expression in development or disease.

Gut microbial pathway identified as target for improved heart disease treatment      (via sciencedaily.com)     Original source 

Researchers have made a significant discovery about how the gut microbiome interacts with cells to cause cardiovascular disease. The study found phenylacetylglutamine (PAG), produced by gut bacteria as a waste product, then absorbed and formed in the liver, interacts with previously undiscovered locations on beta-2 adrenergic receptors on heart cells once it enters the circulation.

Peering into the mind of artificial intelligence to make better antibiotics      (via sciencedaily.com)     Original source 

Artificial intelligence (AI) has exploded in popularity as of late. But just like a human, it's hard to read an AI model's mind. Explainable AI (XAI) could help us do just that by providing justification for a model's decisions. And now, researchers are using XAI to scrutinize predictive AI models more closely, which could help make better antibiotics.

Researchers develop index to quantify circular bioeconomy      (via sciencedaily.com)     Original source 

As the world faces the challenges of mitigating climate change and providing resources for a growing population, there is increasing focus on developing circular economies for sustainable production. But to evaluate strategies and impacts, it is necessary to have reliable metrics. Researchers have now developed a Circularity Index that provides a comprehensive method to quantify circularity in bioeconomic systems. In a new paper, they outline the method and apply it to two case studies -- a corn/soybean farming operation and the entire U.S. food and agriculture system.
