The clicking, buzzing and calling behavioral patterns of elusive East Greenland narwhals have been described thanks to in-depth recordings, in a study published June 13, 2018 in the open-access journal PLOS ONE by Susanna Blackwell from Greeneridge Sciences, Incorporated, United States of America, and colleagues.
People who deeply grasp the pain or happiness of others also process music differently, say researchers at Southern Methodist University, Dallas and UCLA. The study in Frontiers in Behavioral Neuroscience compared MRI scans of low- and high-empathy people. Higher empathy people process music like a pleasurable proxy for a human encounter -- in brain regions for reward and social awareness. The findings may have implications for the function of music now and in our evolutionary past.
Complete brood failure in blue tits is almost always associated with the sudden and permanent disappearance of one of the parents. Peter Santema and Bart Kempenaers from the Max Planck Institute for Ornithology in Seewiesen show in their study that the remaining parent substantially increased its effort to raise at least some of the chicks, which turned out to be successful in two thirds of the nests.
Brasilestes stardusti lived around 70 million years ago and was named after Ziggy Stardust, the singer's iconic persona. Description was based on a fossilized tooth. It's the first indication that placental mammals and dinosaurs co-existed in South America. For scientists, fossil features showed similarities with another prehistoric mammal found in India, suggesting both shared a common ancestral native from the Gondwana supercontinent.
Three new members have been added to the Pandoravirus family by researchers at the CNRS and Aix-Marseille Université, working with partners at CEA, Inserm and Université Grenoble-Alpes. Researchers offer an explanation to their puzzling giant genomes with many orphan genes: pandoviruses appear to be factories for new genes -- and therefore new functions. From freaks of nature to evolutionary innovators, giant viruses continue to shake branches on the tree of life!
Bioengineers from Rice University, Boston University and MIT have created an open-source, do-it-yourself system that combines the control of automated cell-culturing systems that can run for months with the scale of high-throughput systems that grow dozens of cultures at once.
While humans and other species share some of the same genetic information, new research found that humans are unique among mammals when it comes to the types and diversity of microorganisms on our skin. This difference could have implications for our health and immune systems.
Indiana University researchers have directly observed for the first time how bacteria use appendages thousands of times thinner than a human hair to absorb DNA. The work could help advance efforts stop antibiotic-resistant bacteria.
A new University of Colorado Boulder-led study sheds light on the genetic mechanisms that allowed sunflowers to undergo a relatively rapid evolutionary transition from wild to domesticated in just over 5,000 years.
A new technique creates maps of the folded structures of DNA, RNA, and proteins within the cellular nucleus, revealing elegant 'hubs' of organization.
