Baby Babbling Might Lead To Faster Language Development

Newsy (Aug. 29, 2014) — A new study suggests babies develop language skills more quickly if their parents imitate the babies' sounds and expressions and talk to them often. Video provided by Newsy

Explaining How We Differ From Our Closest Ape Relatives

Explaining How We Differ From Our Closest Ape Relatives

FORA.tv (Dec. 22, 2014) — Explaining How We Differ From Our Closest Ape Relatives California Academy of Sciences - Cal Academy of Sciences Walking upright on two legs is the hallmark of the human lineage. Understanding when and how we made the transition to this unique way of moving about the world is key to deciphering how, and why, we evolved. Scientists have traditionally studied hands, feet, arms and legs to understand animal movement, but primates differ in body shape as much as they do in their limbs, and this is related to the ways they are designed to move about the world - whether they hold their bodies upright or horizontally, whether they hang below branches in the trees or walk above them on all fours, and more. Over the past few decades, more bones associated with the trunk, including ribs, pelves and vertebrae, have been discovered for fossil hominins and our relatives, shedding new light on the evolution of body form in apes and humans. In addition, new 3D computer technologies allow us to study these fossils in new ways. These new insights into the evolution of human body form paint a striking new picture of the transition from ape to hominin, leading to a whole new way of thinking about our origins.

Does Social Engagement Have a Genetic Root?

Does Social Engagement Have a Genetic Root?

FORA.tv (May 13, 2013) — Does Social Engagement Have a Genetic Root? California Academy of Sciences - California Academy of Sciences Innovation is critical for both individual and evolutionary success, but creative disruption requires taking risks. New research marrying the theory and methods of economics to cutting-edge neuroscience techniques - an emerging field known as NeuroEconomics - is making new discoveries about the biological processes that motivate us to take risks and create new solutions to unforeseen challenges. Dr. Platt will describe how the brain overcomes uncertainty to explore novel alternatives and create new knowledge. Parallel findings from humans, monkeys, rodents, and worms indicate that a common suite of underlying mechanisms has evolved to control the desire to explore. At one extreme, neuropsychiatric disorders like attention-deficit hyperactivity disorder, obsessive-compulsive disorder, and addiction, may arise from dysfunctional control of exploration. At the other, uniquely human faculties of creativity and technological innovation may reflect elaboration of this shared biological heritage controlling our desire to explore.

Sonar-Jamming Moths Hinder Hungry Bats

Reuters (Sep. 25, 2013) — A tiger moth native to the deserts of Arizona has developed a highly evolved sonar jamming system it uses to fend of attacks by hungry bats. The discovery, described in a paper published in the journal PLOS One, could have applications in the design of acoustic deterrents to protect bats from dangerous wind turbines. Rob Muir reports.
