Zebra stripes are not good landing strips
Published: Wed, 20 Feb 2019 14:50:32 EST
Description: The stripes of a zebra deter horse flies from landing on them, according to a new study.  more...
Bat influenza viruses could infect humans
Published: Wed, 20 Feb 2019 13:35:34 EST
Description: Bats don't only carry the deadly Ebola virus, but are also a reservoir for a new type of influenza virus. These newly discovered flu viruses could potentially also attack the cells of humans and livestock, researchers have now shown.  more...
Can a nerve injury trigger ALS?
Published: Wed, 20 Feb 2019 11:22:08 EST
Description: Researchers have demonstrated that a peripheral nerve injury can trigger the onset and spread of the disease in an animal model of ALS.  more...
Developmental changes resulted in changes to crocodile snouts
Published: Wed, 20 Feb 2019 10:34:00 EST
Description: Despite often being portrayed as creatures that have remained virtually unchanged for millions of years, a new Harvard study shows crocodiles have repeatedly altered their developmental patterns, leading to much of the diversity found in modern, living crocodiles.  more...
Activating tooth regeneration in mice
Published: Wed, 20 Feb 2019 10:33:52 EST
Description: Most reptiles and fish have multiple sets of teeth during their lifetime. However, most mammals, such as humans, have only one set of replacement teeth and some mammals, like mice, have only a single set with no replacement. This diversity raises both evolutionary questions -- how did different tooth replacement strategies evolve? -- and developmental ones -- which mechanisms prevent replacement teeth in animals that lost them?  more...
Foreign bees monopolize prize resources in biodiversity hotspot
Published: Wed, 20 Feb 2019 10:33:39 EST
Description: New research revealed that foreign honey bees often account for more than 90 percent of pollinators observed visiting flowers in San Diego, considered a global biodiversity hotspot. The non-native bees have established robust feral populations and currently make up 75 percent of the region's observed pollinators. Their monopoly over the most abundantly blooming plant species may strongly affect the ecology and evolution of species that are foundational to the stability of the region's plant-pollinator interactions.  more...
Marsupial lived among Arctic dinosaurs
Published: Tue, 19 Feb 2019 13:29:18 EST
Description: A research team has discovered a previously unknown species of marsupial that lived in Alaska's Arctic during the era of dinosaurs, adding a vivid new detail to a complex ancient landscape. The thumb-sized animal, named Unnuakomys hutchisoni, lived in the Arctic about 69 million years ago during the late Cretaceous Period.  more...
Familiarity breeds aggression
Published: Tue, 19 Feb 2019 13:28:00 EST
Description: Aggressiveness among animals may increase the longer individuals live together in stable groups. The study used the Amazon molly, a naturally clonal fish species that produces genetically identical individuals to isolate the effects of familiarity on behavior.  more...
The key to increased lifespan? Rubicon alters autophagy in animals during aging
Published: Tue, 19 Feb 2019 11:17:44 EST
Description: Autophagy is an important biological recycling mechanism that influences the progression of aging in animals. Here, age-related changes in autophagy were studied in multiple model organisms. A team found that Rubicon suppression led to reduction of age-associated motor decline, as well as reduction of fibrosis, and that Rubicon could be an important new target for treatments designed to reduce the effects of aging in humans.  more...
Homo sapiens colonized South Asian rainforest by hunting small mammals 45,000 years ago
Published: Tue, 19 Feb 2019 11:17:01 EST
Description: A new study provides direct evidence for the hunting of tree-dwelling monkeys and other small mammals by Homo sapiens 45,000 years ago in the rainforest of Sri Lanka.  more...
