New model helping identify pregnant women whose previous kidney injury puts them, babies at risk

Scientists developed a rodent model to understand and identify young pregnant women who have previously suffered kidney injuries, which can lead to complications such as preeclampsia and low birthweight. The model suggests that even years after the injury, some women may still experience renal insufficiency during pregnancy.

A research team identifies a metabolic footprint associated with the perception of satiety

A research team has discovered a metabolic footprint associated with the perception of satiety, revealing that higher concentrations of glycine and linoleic acid are linked to increased satiety. The study involved 140 volunteers with overweight and obesity, showing that certain metabolites in the blood can predict postprandial satiety.

Rice's Yingyan Lin receives NSF CAREER Award

Yingyan Lin, an assistant professor at Rice University, has received a $400,000 NSF CAREER Award to develop more efficient deep learning hardware accelerators. Her goal is to push forward ubiquitous intelligent devices and green artificial intelligence, addressing the gap between complex algorithms and limited resources.

Screening for macrocyclic peptides

Researchers designed a simple screening assay based on competitive binding to identify peptide candidates with high binding affinity for ubiquitin. The dimers of cyclic peptides were found to be more potent than control peptides and induced cell death in live cancer cell lines.

Distorting memories helps the brain remember

New research published in JNeurosci found that recalling similar memories triggers divergent brain activity patterns, resulting in better memory performance. This study suggests that the brain exaggerates differences between similar events, which can be advantageous in distinguishing between similar things and preventing confusion.

Dogs synchronize their behavior with children, but not as much as with adults, study finds

A study from Oregon State University found that dogs synchronize their behavior with children, but not as much as they do with adults. The researchers observed that dogs exhibited behavioral synchronization with children at a higher rate than expected by chance, particularly in terms of active synchrony and proximity. However, the leve...

Worker bees smell trouble in the colonies

Research reveals that worker bees can detect varroa-related compounds in brood cells, triggering a strong behavioral response to defend against the parasite. This finding has implications for breeding programs aimed at developing stronger resistance to Varroa destructor in honey bee colonies.

Neural pathway critical to correcting behavioral errors related to psych disorders found

Mount Sinai researchers identified a neural pathway that detects errors and guides subsequent behavioral improvement, which is frequently dysregulated in psychiatric disorders. They also suggest that neurostimulation of this brain pathway could provide an important mechanism for attention adjustments following behavioral errors.
