For starlings and meerkats in the Kalahari Desert, the fork-tailed drongo, a songbird with glossy black feathers and garnet-red eyes, is like the neighborhood dog: a trustworthy pal that’s always on the alert and ready to warn you about dangerous predators. Except when it’s lying. Because sometimes drongos, which are about the size of a scrub jay, make false alarm…
A mother’s diet before conception can permanently affect how her child’s genes function, according to a study published in Nature Communications. The first such evidence of the effect in humans opens up the possibility that a mother’s diet before pregnancy could permanently affect many aspects of her children’s lifelong health. Researchers from the MRC International Nutrition Group, based at the London…
Scientists studying social learning in animals have shown how easy it can be to introduce a new behavior into a group and watch it spread from individual to individual. However, not nearly as many studies are devoted to following up on the establishment of new behaviors to see if those behavioral traditions persist. In a new study,Tina Gunhold, Jorg Massen,…
Scientists working to sequence all manner of bacteria, Archaea, plants, and animals and to make these genomes publicly available hope to use the data to inform health, industrial, and environmental issues. Large-scale sequencing consortia have been churning out data at an impressive rate, yet significant gaps remain in the genomic tree of life. And while these groups have largely been…
It is better to give than to receive — at least if you’re an adolescent and you enjoy giving, a new study suggests. The study found that 15- and 16-year-olds who find pleasure in pro-social activities, such as giving their money to family members, are less likely to become depressed than those who get a bigger thrill from taking risks…
Cochlear implants are among the most successful bionic devices ever developed. Available since the 1970s, they have restored some measure of hearing to more than 300,000 people around the world. Now, scientists from the University of New South Wales have found a way of making the implants even more effective—by turning them into delivery vehicles for genes that promote the…
