They are known as the hippies of the ape kingdom, a peaceful and affectionate species that is more interested in making love than killing each other. One of the world’s rarest apes, bonobos are close cousins of chimpanzees and share 98.7% of human DNA. But unlike their ape relatives — and humans — bonobos shy…
Fears that sex-linked chromosomes, such as the male Y chromosome, are doomed to extinction have been refuted in a new genetic study which examines the sex chromosomes of chickens. The study, published in the journal Proceedings of the National Academy of Sciences, looked at how genes on sex-linked chromosomes are passed down generations and linked…
Although the world produces enough food to feed everyone, two million children die of malnutrition every year. Food insecurity has become a symbol of inequity and remains the most crippling consequence of poverty. Campaigners for food security must include science in their goals — and in return scientists need to heed wider concerns around solutions….
The authors of a Harvard study published in Nature Climate Change gathered their data from an unlikely source—the trip accounts of the Massachusetts Butterfly Club. Over the past 19 years, the amateur naturalist group has logged species counts on nearly 20,000 expeditions throughout Massachusetts. Their records fill a crucial gap in the scientific record. Once…
Lynn Margulis is justly celebrated for her determined claim that the eukaryotic cell (the more complex cell with a nucleus and other parts, organelles) is not something that evolved on its own. It is rather the result of a simpler (prokaryotic) cell incorporating other such cells, which latter (rather than being absorbed) continued their existence within the whole, developing their own contributory functions.
