Why testing lemur color vision is harder than it looks

Elphaba the aye-aye takes a vision test at the Duke Lemur Center in Durham, North Carolina. She’s getting encouragement from student researcher Joe Sullivan and technician Jennifer Templeton. Photo by David Haring. Elphaba the aye-aye is not an early riser. A nocturnal primate with oversized ears, bulging eyes and long, bony fingers, she looks like […]

Brazil scientists discover three new toad species

This handsome creature, photographed in Garuva, Santa Catarina state, Brazil, belongs to one of three newly discovered species of wee toads identified in mountainous regions of the so-called Atlantic tropical forest Brazilian scientists announced Wednesday the discovery of three previously unknown species of poisonous toads in the fast-shrinking Atlantic forest of southern Brazil, an area […]

Over 300 new beetle records for New Brunswick, Canada

The cover of the special issue of open-access journal ZooKeys, devoted to the beetle diversity and natural history in New Brunswick, Canada. Credit: ZooKeys Beetles diversity in New Brunswick, Canada, has elicited the interest of biologists for over a century and continues to do so. In 1991, 1,365 species were known from New Brunswick. That […]

Stopping malaria one mosquito at a time

Stopping malaria one mosquito at a time

«This is a significant step,» says Distinguished Professor Anthony James, holding up a vial of genetically modified mosquitoes. «This method allows us to efficiently create large populations of mosquitoes unable to transmit malaria.» Credit: Steve Zylius/UC Irvine Anthony James doesn’t dislike mosquitoes. He just doesn’t want them to transmit malaria. The University of California, Irvine […]

Microbe with stripped-down DNA may hint at secrets of life

Microbe with stripped-down DNA may hint at secrets of life

This photo provided by National Center for Imaging and Microscopy Research at the University of California at San Diego shows Electron micrographs of clusters of JCVI-Syn 3.0 cells magnified about 15,000 times. This is the world’s first minimal bacterial cell. Its synthetic genome contains only 473 genes. Surprisingly, the functions of 149 of those genes […]

Killifish project explores the genetic foundation of longevity

  Turquoise killifish. Credit: Wikipedia. Researchers at the Stanford University School of Medicine have mapped the genome of an unusually short-lived fish, paving the way for scientists to use the organism to study how genes influence longevity. The researchers will publish the genome map of the African turquoise killifish Dec. 3 in Cell, along with […]

Unique beak evolved with tool use in New Caledonian crow

Unique beak evolved with tool use in New Caledonian crow

  A 3-D reconstruction of the New Caledonian Crow skull with key measuring points. Credit: Matsui et al. (2016) It was as plain as the beak on a bird’s face. Cornell ornithologist and crow expert Kevin McGowan recalls the day in the late 1990s when he first saw stuffed specimens of the New Caledonian crow. […]
