Monkey Vocabulary Decoded
Published: Thu, 22 Feb 2018 15:02:42 EST
Description: From short 'tsiks' and 'ekks' to drawn-out 'phees' -- all the sounds produced by marmoset monkeys are made up of individual syllables of fixed length, according to a new study. The smallest units of vocalization and their rhythmic production in the brain of our relatives could also have been a prerequisite of human speech.  altro...
Surprising new study redraws family tree of domesticated and 'wild' horses
Published: Thu, 22 Feb 2018 14:51:32 EST
Description: New research overturns a long-held assumption that Przewalski's horses, native to the Eurasian steppes, are the last wild horse species on Earth.  altro...
In living color: Seeing cells from outside the body with synthetic bioluminescence
Published: Thu, 22 Feb 2018 14:50:18 EST
Description: Glowing creatures like fireflies and jellyfish are captivating to look at but also a boon for science, as their bioluminescent molecules contribute to visualizing a host of biological processes. Now, scientists have supercharged these molecules, making them hundreds of times brighter in deep tissues and allowing for imaging of cells from outside the body. The bioengineered light source was used to track cancer cells in mice and brain-cell activity in monkeys, but its applications extend beyond the lab.  altro...
How bats carry viruses without getting sick
Published: Thu, 22 Feb 2018 14:50:05 EST
Description: Bats are known to harbor highly pathogenic viruses like Ebola or Marburg and yet they do not show clinical signs of disease. Scientists find that in bats, an antiviral immune pathway called the STING-interferon pathway is dampened, and bats can maintain just enough defense against illness without triggering a heightened immune reaction.  altro...
Locomotion of bipedal dinosaurs might be predicted from that of ground-running birds
Published: Wed, 21 Feb 2018 14:09:43 EST
Description: A new model based on ground-running birds could predict locomotion of bipedal dinosaurs based on their speed and body size, according to a new study.  altro...
Movement behavior of an anole species surprisingly dynamic
Published: Wed, 21 Feb 2018 12:29:25 EST
Description: Anolis lizards have a thing or two to teach humans about love -- or in scientific speak, sexual selection -- at least when it comes to territoriality. Decades of behavioral research on the lizard's mating systems have resulted in near-unanimous agreement among scientists that the males maintain restricted, static territories to defend exclusive mating access to females within these territories and are consequently polygamous.  altro...
Asian elephants have different personality traits just like humans
Published: Wed, 21 Feb 2018 12:29:15 EST
Description: Researchers have studied a timber elephant population in Myanmar and discovered that Asian elephant personality manifests through three different factors. The personality factors identified by the researchers are Attentiveness, Sociability and Aggressiveness.  altro...
Beluga whales dive deeper, longer to find food in Arctic
Published: Tue, 20 Feb 2018 16:12:16 EST
Description: Beluga whales that spend summers feeding in the Arctic are diving deeper and longer to find food than in earlier years, when sea ice covered more of the ocean for longer periods, according to a new analysis.  altro...
Helping in spite of risk: Ants perform risk-averse sanitary care of infectious nest mates
Published: Tue, 20 Feb 2018 16:11:59 EST
Description: Ants care for their sick nest mates in different ways, depending on their own immune status. When they themselves are susceptible to dangerous superinfections, they use a different method to care for sick colony members compared to ants that are not susceptible, thus protecting themselves from infection.  altro...
Cracking the genetic code for complex traits in cattle
Published: Tue, 20 Feb 2018 12:30:34 EST
Description: The global 1000 Bull Genomes Consortium identified the genetic basis for accurately predicting the complex trait of height across cattle and dairy breeds by pooling large genomic datasets and phenotypes collected from 58,000 cattle. The team validated their findings using the DNA of a wild auroch, the ancient ancestor to all cattle and dairy breeds, and, in a world first, demonstrated the genes influencing height in cattle also influence the trait in humans and dogs.  altro...
