Cutting-edge 'protein lawnmower' created      (via sciencedaily.com)     Original source 

Scientists have designed the first synthetic protein-based motor which harnesses biological reactions to fuel and propel itself. 'Imagine if a Roomba could be powered only by the dirt it picks up,' says one of the authors of the study. The motor uses the digestive enzyme trypsin to cut the peptides and convert them into the energy it needs to propel itself.

What will it take for China to reach carbon neutrality by 2060?      (via sciencedaily.com)     Original source 

To become carbon neutral by 2060, China will have to build eight to 10 times more wind and solar power installations than existed in 2022, according to a new study. Reaching carbon neutrality will also require major construction of transmission lines.

The small intestine adapt its size according to nutrient intake      (via sciencedaily.com)     Original source 

Resizing of the intestine is a highly conserved strategy employed by a wide range of organisms to cope with fluctuation in nutrient availability. Nevertheless, very little is known about the mechanisms and signals underlying nutrient-mediated gut resizing. New research has identified one of the signaling pathways implicated in this process.

Biomolecular condensates -- regulatory hubs for plant iron supply      (via sciencedaily.com)     Original source 

Iron is a micronutrient for plants. Biologists now show that regulatory proteins for iron uptake behave particularly dynamically in the cell nucleus when the cells are exposed to blue light -- an important signal for plant growth. They found that the initially homogeneously distributed proteins relocated together into 'biomolecular condensates' in the cell nucleus shortly after this exposure.

Researchers harness 2D magnetic materials for energy-efficient computing      (via sciencedaily.com)     Original source 

Researchers used ultrathin van der Waals materials to create an electron magnet that can be switched at room temperature. This type of magnet could be used to build magnetic processors or memories that would consume far less energy than traditional devices made from silicon.

Metabolic diseases may be driven by gut microbiome, loss of ovarian hormones      (via sciencedaily.com)     Original source 

Mice that received fecal implants from donors that had their ovaries removed gained more fat mass and had greater expression of liver genes associated with inflammation, Type 2 diabetes, fatty liver disease and atherosclerosis. The findings may shed light on the greater incidence of metabolic dysfunction in postmenopausal women.

Method identified to double computer processing speeds      (via sciencedaily.com)     Original source 

Scientists introduce what they call 'simultaneous and heterogeneous multithreading' or SHMT. This system doubles computer processing speeds with existing hardware by simultaneously using graphics processing units (GPUs), hardware accelerators for artificial intelligence (AI) and machine learning (ML), or digital signal processing units to process information.

New water batteries stay cool under pressure      (via sciencedaily.com)     Original source 

A global team of researchers has invented recyclable 'water batteries' that won't catch fire or explode. The team use water to replace organic electrolytes -- which enable the flow of electric current between the positive and negative terminals -- meaning their batteries can't start a fire or blow up -- unlike their lithium-ion counterparts.

New system triggers cellular waste disposal      (via sciencedaily.com)     Original source 

Established treatments for cancer and other diseases often focus on inhibiting harmful enzymes to mitigate their effects. However, a more innovative approach has emerged: harnessing the cell's natural waste disposal system not just to deactivate but to entirely eradicate these proteins. Researchers have previously demonstrated the efficacy of this approach through two distinct methods. Now they unveil a third system capable of targeting and disposing of previously inaccessible proteins.

Bridging diet, microbes, and metabolism: Implications for metabolic disorders      (via sciencedaily.com)     Original source 

Mounting evidence suggests that the secret to understanding human health and combating metabolic diseases lies hidden within the microscopic world of our gut bacteria. Recent research reveals that a specific fatty acid produced by gut bacteria directly influences fat metabolism in animals. This research is pivotal as it sheds light on the complex interplay between the diet, gut microbiota, and host metabolic health, offering insights that could open new avenues in our approach to managing metabolic disorders.

Photosynthetic mechanism of purple sulfur bacterium adapted to low-calcium environments      (via sciencedaily.com)     Original source 

Purple sulfur bacteria (PSB) convert light energy into chemical energy through photosynthesis. Interestingly, certain species can photosynthesize even in environments with low-calcium levels. Using cryo-electron microscopy, researchers unveiled the structure of light-harvesting complexes and elucidated the mechanism that facilitates photosynthesis under low-calcium conditions.
