<jats:title>Genomics of radiation-induced damage</jats:title> <jats:p> The potential adverse effects of exposures to radioactivity from nuclear accidents can include acute consequences such as radiation sickness, as well as long-term sequelae such as increased risk of cancer. There have been a few studies examining transgenerational risks of radiation exposure but the results have been inconclusive. Morton <jats:italic>et al.</jats:italic> analyzed papillary thyroid tumors, normal thyroid tissue, and blood from hundreds of survivors of the Chernobyl nuclear accident and compared them against those of unexposed patients. The findings offer insight into the process of radiation-induced carcinogenesis and characteristic patterns of DNA damage associated with environmental radiation exposure. In a separate study, Yeager <jats:italic>et al.</jats:italic> analyzed the genomes of 130 children and parents from families in which one or both parents had experienced gonadal radiation exposure related to the Chernobyl accident and the children were conceived between 1987 and 2002. Reassuringly, the authors did not find an increase in new germline mutations in this population. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" related-article-type="in-this-issue" xlink:href="10.1126/science.abg2538">eabg2538</jats:related-article> , p. <jats:related-article issue="6543" page="725" related-article-type="in-this-issue" vol="372">725</jats:related-article> </jats:p>

<jats:p>As several countries now confront COVID-19 surges, Israel may be crossing over to other side of the pandemic. Whereas 5.5 million new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections were reported globally last week, Israel reported only 398 (compared with &gt;50,000 in January). Already, 54% of Israel's 9.2 million citizens have been fully vaccinated, considerably more than in most other countries. In the coming months, as restrictions continue to ease, the country should be optimistic, yet cautious, as risks of resurgence persist. Israel thus may well be an early case study for favorable outcomes of a mass-vaccination campaign.</jats:p>
