We summarize the week's scientific breakthroughs every Thursday.
A study of 50 crab species in Japan traces the iconic sideways walk to a single ancestor, suggesting the trait drove the group's remarkable diversity.
British chef Mike Keen will ski across Greenland eating only fermented seal. Researchers will study how the Inuit diet shapes gut health.
Female rats prefer gentler tickling, a finding that could reshape animal happiness research.
Scientists still don’t know why Andes hantavirus is the only one shown to spread from person to person.
Male primates may be larger than females partly because of pressure from rival groups, not just competition with males inside their own group.
Scientists use simulated dinosaurs to trigger real insect brains and test how wings originally evolved.
DNA damage from inflammation outpaces the cells’ ability to self-repair. The finding, in human brain cells and mice, could point to new MS treatments.
A new study shows learning to fly in virtual reality with virtual wings can reshape the brain, making it treat wings more like body parts.
Finds at sites in Spain and France suggest that Neandertals used the teeth of ancient rhinos for heavy-duty fabrication.
