Survival tactics: AI-driven insights into chromatin changes for winter dormancy in axillary buds      (via sciencedaily.com)     Original source 

Epigenetics confers a survival advantage in plants to endure harsh weather by inducing bud dormancy. Environmental factors or intrinsic signals trigger the transition between growth and dormancy. Researchers explore the role of chromatin and transcriptional changes in the bud and further analyze data using artificial intelligence models. The findings of this study highlight epigenetic strategies to overcome the effects of short winters during global warming for plant survival.

The power of face time: Insights from zebra finch courtship      (via sciencedaily.com)     Original source 

A new study on songbirds sheds light on the power of social interaction to facilitate learning, insights that potentially apply to human development. Researchers discovered that zebra finches deprived of early social experiences could still form strong bonds with a partner later in life. Once placed into cohabitation with a male, females that had never heard a mating song before could quickly develop a preference for his melody.

'DNA scavengers' can stop some antibiotic resistance from spreading      (via sciencedaily.com)     Original source 

For nearly a century, scientists have waged war on antibiotic-resistant microbes. Researchers say they've found a new way to prevent it -- by unleashing 'DNA scavengers' in wastewater treatment plants.

Engineered Bacteria make thermally stable plastics similar to polystyrene and PET      (via sciencedaily.com)     Original source 

Bioengineers around the world have been working to create plastic-producing microbes that could replace the petroleum-based plastics industry. Now, researchers have overcome a major hurdle: getting bacteria to produce polymers that contain ring-like structures, which make the plastics more rigid and thermally stable. Because these molecules are usually toxic to microorganisms, the researchers had to construct a novel metabolic pathway that would enable the E. coli bacteria to both produce and tolerate the accumulation of the polymer and the building blocks it is composed of. The resulting polymer is biodegradable and has physical properties that could lend it to biomedical applications such as drug delivery, though more research is needed.

Benefits and downside of fasting      (via sciencedaily.com)     Original source 

Researchers identified a signaling pathway in mice that boosts intestinal stem cells' regeneration abilities after fasting. When cancerous mutations occurred during this regenerative period, mice were more likely to develop early-stage intestinal tumors.

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.

'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.
