One-quarter of the Chondrichthyes have an elevated risk of extinction, mainly as a result of overfishing.

A transcriptome-based metric for aging reveals a longevity mechanism that specifically prolongs the duration of young adulthood rather than slowing overall aging.

A tumor-specific regulatory region has been identified upstream of the Myc oncogene.

HLA-B*35:01 molecules that are peptide-deficient are thermostable, bind CD8 with higher affinity than their peptide-filled versions, accumulate at immunological synapses and enhance antigen-specific CD8+ T cell immune responses.

Population mutation rates are highly flexible and evolvable under extreme stress conditions, matching changes in selective pressure to avoid extinction of the entire population.

Genetic incompatibilities are common and widely distributed throughout the genomes of swordtail fish, and prevent the regions of the genome around them from being exchanged between different species.

ECF-CbrT is a bacterial vitamin B12 transporter that is structurally different from the well-characterized transporter BtuCDF, yet has similar functional properties.

Combining pre-erythrocytic and transmission blocking antibodies enhances the overall control and potential elimination of malaria within both mosquito and vertebrate populations.

A high throughput, full lifespan microscopic analysis reveals that fission yeast does not age but has a finite replicative lifespan.
