Examining the role of common variants in rare neurodevelopmental conditions.

Although rare neurodevelopmental conditions have a large Mendelian component, common genetic variants also contribute to risk. However, little is known about how this polygenic risk is distributed among patients with these conditions and their parents nor its interplay with rare variants. It is also unclear whether polygenic background affects risk directly through alleles transmitted from parents to children, or whether indirect genetic effects mediated through the family environment also play a role.

ReNU syndrome - a newly discovered prevalent neurodevelopmental disorder.

Two recent papers have identified genetic variants in the noncoding gene RNU4-2 to cause a frequent neurodevelopmental disorder. This work will have a substantial impact on the rare disease community, leading to thousands of diagnoses worldwide. These studies also highlight the untapped diagnostic potential of noncoding regions.

The genetic basis of predation by myxobacteria.

Myxobacteria (phylum Myxococcota) are abundant and virtually ubiquitous microbial predators. Facultatively multicellular organisms, they are able to form multicellular fruiting bodies and swarm across surfaces, cooperatively hunting for prey. Myxobacterial communities are able to kill a wide range of prey microbes, assimilating their biomass to fuel population growth.

Feedback and Financial Incentives for Reducing Cell Phone Use While Driving: A Randomized Clinical Trial.

Importance: Handheld phone use while driving is a major factor in vehicle crashes. Scalable interventions are needed to encourage drivers not to use their phones.

Objective: To test whether interventions involving social comparison feedback and/or financial incentives can reduce drivers' handheld phone use.
