Chimpanzees may throw tantrums like toddlers, but their total brain size suggests they have more self-control than, say, a gerbil or fox squirrel, according to a new study of 36 species of mammals and birds ranging from orangutans to zebra finches. Scientists at Duke University, UC Berkeley, Stanford, Yale and more than two-dozen other research institutions collaborated on this first…
Scientists have grown stem cells from adults using cloning techniques for the first time — bringing them closer to developing patient-specific lines of cells that can be used to treat a whole host of ailments, from heart disease to blindness. The research, described in Thursday’s online edition of the journal Cell Stem Cell, is a controversial advance likely to reopen…
The two marmosets—small, New World monkeys—had been a closely bonded couple for more than 3 years. Then, one fateful day, the female had a terrible accident. She fell out of a tree and hit her head on a ceramic vase that happened to be underneath on the forest floor. Her partner left two of their infants alone in the tree…
A team of researchers from the University of California, San Diego School of Medicine and the Center for Cancer Systems Biology (CCSB) at the Dana-Farber Cancer Institute has uncovered a new aspect of autism, revealing that proteins involved in autism interact with many more partners than previously known. These interactions had not been detected earlier because they involve alternatively spliced…
A team of international scientists, including a trio from Simon Fraser University, has published the world’s first ranking of evolutionary distinct birds under threat of extinction. These include a cave-dwelling bird that is so oily it can be used as a lamp and a bird that has claws on its wings and a stomach like a cow. The research, published today in Current Biology,…
The ability to disengage from our own desire to cater to someone else’s wishes is thought to be a unique feature of human cognition. In a study published in the journal, Biology Letters, Prof Clayton and her colleagues challenge this assumption. Despite wanting something different to eat, male Eurasian jays can disengage from their own current desire in order to feed the female what…
