BRAIN ACTIVITY MAY MARK THE BEGINNING OF MEMORIES


By tracking brain activity when an animal stops to look around its environment, neuroscientists at the Johns Hopkins University believe they can mark the birth of a memory. Using lab rats on a circular track, James Knierim, professor of neuroscience in the Zanvyl Krieger Mind/Brain Institute at Johns Hopkins, and a team of brain scientists […]

As I understand it, our story begins when French orphan Martin Fugate settled on the banks of […]

Setting blurred images in motion improves perception


‘Optic flow’ is especially important for people with low vision, says study in optometry and vision science   Blurred images that are unidentifiable as still pictures become understandable once the images are set in motion. That’s because of a phenomenon called “optic flow”—which may be especially relevant as a source of visual information in people […]

Seeing the forest and the trees


A new technique for panoramic, very-high-resolution, time-lapse photography for plant and ecosystem research Ever wonder what plants do when you’re not around? How about an entire forest or grassland? Not even the most dedicated plant researcher can be continuously present to track environmental effects on plant behavior, and so numerous tools have been developed to […]

Statins and memory loss


Study finds link between commonly prescribed statin and memory impairment New research that looked at whether two commonly prescribed statin medicines, used to lower low-density lipoprotein (LDL) or ‘bad cholesterol’ levels in the blood, can adversely affect cognitive function has found that one of the drugs tested caused memory impairment in rats. Between six and […]

3 new species of tiny frogs from the remarkable region of Papua New Guinea


Three new species of tiny frogs from Papua New Guinea are described in the latest issue of Zookeys. Dr Fred Kraus,University of Michigan, who in 2011 in Zookeys described the world’s smallest frogs Paedophryne dekot and Paedophryne verrucosa, now adds another 3 species from the genus Oreophryne to the remarkable diversity of this region. The three new species Oreophryne cameroni, Oreophryneparkopanorum and Oreophrynegagneorum are all rather minute, with total […]
