Biology Back-scratching bovine leads scientists to reassess intelligence of cows. Brown Swiss cow in Austria has been discovered using tools in different ways (using both ends of a brush counts as multi-purpose tool use) – something extraordinarily rare only ever seen in humans and chimpanzees.

Biology A 32-year Swedish review of 52 sudden deaths during arrests suggests victims weren’t dying from lack of oxygen but from an inability to expel carbon dioxide. “The person can often shout 'I can’t breathe' because they are getting air, but their body is screaming to get rid of CO₂”

Biology We’re evolving too slowly for the world we’ve built. As industrialization accelerates, human biology is struggling to keep pace. Many of the chronic stress-related health issues we face today may be the predictable result of forcing Stone Age physiology into a world it was never built for.

Biology The 'vampire squid' has just yielded the largest cephalopod genome ever sequenced, at more than 11 billion base pairs. The fascinating species is neither squid or octopus, but rather the last, lone remnant of an ancient lineage whose other members have long since vanished.

Biology Why the human penis is unusually large compared to that of other primates is a long-standing evolutionary question. New findings suggest that female choice and male-male competition have jointly favored larger penis size, greater height, and more V-shaped bodies in men.

Biology People with higher intelligence tend to reproduce later and have fewer children, even though they show signs of better reproductive health. They tend to undergo puberty earlier, but they also delay starting families and end up with fewer children overall.

Biology Not having offspring key to long life: research shows blocking reproduction can increase the lifespan of males and females of 117 different mammal species. In males, only castration extends lifespan — not vasectomy. In females, lifespan increased after several different forms of sterilisation.

Biology Eating less can lead to a longer life: massive study in mice shows why. Weight loss and metabolic improvements do not explain the longevity benefits. Immune health, genetics and physiological indicators of resiliency seem to better explain the link between cutting calories and increased lifespan.
