Tingxiang Zou to lead a new Emmy Noether group

University of Bonn
Grant and Award Announcement

Philosophy at Peking University, Logic in Amsterdam, and then Mathematics in Lyon ... for Dr. Tingxiang Zou, borders are an invitation rather than an obstacle. Tingxiang Zou is taking on a big new challenge at the Hausdorff Center for Mathematics (HCM), a Cluster of Excellence at the University of Bonn, where she will start leading a newly formed Emmy Noether group at the Mathematical Institute this September, focusing on the Elekes-Szabó problem. The German Research Foundation (DFG) will be providing up to 1.6 million euros in funding for the research group over the next six years. The Emmy Noether Program opens up the possibility for Tingxiang Zou to qualify for a professorship.

Trends in poverty and birth outcomes in the US

JAMA Network
Peer-Reviewed Publication

About The Study: This study found stark disparities in birth outcomes by poverty status, with inequities growing for low birth weight in recent years. These disparities point to the need for more support during pregnancy and birth for low-income families. Antipoverty policies can provide needed resources to promote better maternal and child health, although the availability and generosity of these programs vary across states.

Heterogeneity of treatment effects of GLP-1 RAs for weight loss in adults

JAMA Network
Peer-Reviewed Publication

About The Study: In this systematic review and meta-analysis, glucagon-like peptide-1 receptor agonists (GLP-1 RAs) produced greater weight loss among women than men; however, their efficacy was consistent across other important subpopulations. These findings may inform clinical decision-making.

Within-person association between daily screen use and sleep in youth

JAMA Network
Peer-Reviewed Publication

About The Study: Per the results of this systematic review and meta-analysis, daily screen time has a small but significant within-person correlation with later sleep onset; however, short-term daily fluctuations in screen time appear to have minimal impact on sleep duration, efficiency, or quality. Screen time may delay bedtime but is not inherently detrimental to other aspects of sleep health in youth, contrasting with between-person studies showing stronger adverse associations.

Low-dose lithium for mild cognitive impairment

JAMA Network
Peer-Reviewed Publication

About The Study: This pilot randomized clinical trial established feasibility, confirmed safety and tolerability, and generated effect size estimates for future trials of low-dose lithium in mild cognitive impairment. None of the coprimary outcomes met the prespecified significance threshold.
