Antibiotic resistance in dolphins mirrors disturbing trend in humans

Antibiotic resistance in bottlenose dolphins shows that up to 88% of pathogenic organisms in this species is resistant to one or more antibiotics. This finding offers very useful insights into the identical phenomenon in humans. This species is termed a sentinel species, which means it reflects environmental risks to humans in advance of their occurrence in humans.

Study shows how the immune system achieves antibody diversity

Diversity is good, especially when it comes to antibodies. It's long been known that a gene assembly process called V(D)J recombination allows our immune system to mix and match bits of genetic code, generating new antibodies to conquer newly encountered threats.
