<jats:title>An ever-growing human footprint</jats:title> <jats:p> Human activities are increasingly affecting the marine environment but understanding how much and in what ways is an extreme challenge given the vastness of this system. O'Hara <jats:italic>et al.</jats:italic> looked at a suite of human-induced stressors on &gt;1000 marine species over the course of 13 years. They found that species are experiencing increasing levels of stress over more than half of their ranges, with some species having an even higher proportion of their ranges affected. Fishing has the largest impact, but other stressors, such as climate change, are also important and growing. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article issue="6537" page="84" related-article-type="in-this-issue" vol="372">84</jats:related-article> </jats:p>

<jats:title>A dissipative quantum gas of light</jats:title> <jats:p> Our textbook understanding of quantum systems tends to come from modeling these systems isolated from the environment. However, an emerging focus is understanding how many-body quantum systems behave when interacting with their surroundings and how they subsequently become dissipative, or non-Hermitian, systems. Öztürk <jats:italic>et al.</jats:italic> formed a quantum condensate of light by trapping photons in an optical cavity, a system that is naturally dissipative. By altering the trapping conditions, they demonstrated that the system provides a powerful platform with which to explore the complex dynamics and phase transitions occurring in dissipative quantum systems. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article issue="6537" page="88" related-article-type="in-this-issue" vol="372">88</jats:related-article> </jats:p>

<jats:title>DNA repair within neurons</jats:title> <jats:p> Humans have only a limited capacity to generate new neurons. These cells thus need to repair errors in the genome. To better understand this process, Reid <jats:italic>et al.</jats:italic> developed Repair-seq, a method to locate DNA repair within the genome of stem cell–derived neurons. DNA repair hotspots (DRHs) were more likely to occur within specific genomic features such as gene bodies as well as in genomic formations, open chromatin, and active regulatory regions. This method showed that repair was enriched at sites involved in neuronal function and identity. Furthermore, proteomic data indicated that genes in DRHs are enriched in Alzheimer's disease and that DRHs are more active in aging. These observations link neuronal DNA repair to aging and neurodegeneration. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article issue="6537" page="91" related-article-type="in-this-issue" vol="372">91</jats:related-article> </jats:p>
