Human-wildlife overlap expected to increase across more than half of land on Earth by 2070      (via sciencedaily.com)     Original source 

Human-wildlife overlap could increase across about 57% of the global lands by 2070 and could lead to more conflict between people and animals. Understanding where the overlap is likely to occur -- and which animals are likely to interact with humans in specific areas -- will be crucial information for urban planners, conservationists and countries that have pledged international conservation commitments.

Highest prediction of sea-level rise unlikely      (via sciencedaily.com)     Original source 

A new study challenges as highly unlikely an alarming prediction of sea-level rise that -- while designated as low likelihood --earned a spot in the latest UN climate report for its projection that the collapse of polar ice sheets could make the world's oceans up to 50 feet higher by 2300. But researchers found that the model is based on inaccurate physics of how ice sheets retreat and break apart, though they stress that the accelerating loss of ice from Greenland and Antarctica is still dire.

New study reveals devastating power and colossal extent of a giant underwater avalanche off the Moroccan coast      (via sciencedaily.com)     Original source 

New research has revealed how an underwater avalanche grew more than 100 times in size causing a massive trail of destruction as it traveled 2000km across the Atlantic Ocean seafloor off the North West coast of Africa. Researchers provide an unprecedented insight into the scale, force and impact of one of nature's mysterious phenomena, underwater avalanches.

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.

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.

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.

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.
