Red blood cells have been modified to form strong clots that halt any bleeding almost instantly and then promote tissue regeneration.

In fertilized egg cells, the maternal and paternal genomes are enclosed in separate compartments called pronuclei. Experiments in mice reveal that this spatial separation enables parental competition for cytoplasmic factors, which helps to prevent the dysregulation of chemical modifications to DNA-packing proteins and contributes to healthy embryonic development.

Two comprehensive data sets concerning students who graduated from 141 business schools over 29 years and 200 law schools over 21 years show that higher racial diversity is associated with higher median salary at graduation. Policies that promote racial diversity seem likely to enhance education and benefit society overall.

In people with advanced skin cancer, injecting low doses of an anticancer immunotherapy directly into tumours, rather than administering high doses intravenously, reduced severe immune toxicity while preserving antitumour efficacy. Pre-existing antitumour immunity predicted clinical benefit most strongly, and profiling fresh tissue provided response biomarkers faster than conventional diagnostics did.
