A study in mice and humans reveals that high estrogen levels disrupt a specific neural circuit from the lateral hypothalamus to the hippocampus, causing temporary memory impairment. This finding provides a biological basis for the phenomenon of 'pregnancy brain' or 'mom brain'.
A team of researchers from Kyoto University created a machine-learning model to design microbial communities that promote tomato growth and stress tolerance. The communities, composed of six bacteria and the tomatine metabolite, were found to improve tomato growth and tolerance to high-temperature stress in laboratory and outdoor trials.
Researchers investigated three concrete mixes in four locations with varying climatic conditions. Their study shows that climate plays a significant role in how quickly steel in the concrete rusts. Key findings include that low-carbon concrete can last for 50 years or more in some locations, but may suffer damage sooner under different...
A Phase 3 trial found that oral edaravone improved functional recovery in AIS patients who did not receive reperfusion therapy, with 65.4% achieving a modified Rankin Scale score of 0-1 at 90 days. The treatment was safe and showed consistent benefits across predefined subgroups, supporting the neuroprotective properties of edaravone.
