Why are there so many types of lizards?
Published: Fri, 23 Feb 2018 15:18:44 EST
Description: Researchers have sequenced the complete genetic code -- the genome -- of several vertebrate species from Panama. They found that changes in genes involved in the interbrain (the site of the pineal gland and other endocrine glands), for color vision, hormones and the colorful dewlap that males bob to attract females, may contribute to the formation of boundaries between species. Genes regulating limb development also evolved especially quickly.  more...
Domestic goat dating back to the Neolithic Corded Ware period identified in Finland
Published: Fri, 23 Feb 2018 11:15:48 EST
Description: Goat hairs have been found in a grave structure that was discovered in the 1930s in Kauhava, western Finland. These are the oldest animal hairs found in Finland. From the perspective of Finnish prehistory, the finding supports the evidence of animal husbandry practised during the Corded Ware period, while also revealing details of burial rituals.  more...
Playing both ends: Amphibian adapted to varied evolutionary pressures
Published: Fri, 23 Feb 2018 09:21:45 EST
Description: Caecilian, Siphonops annulatus, a limbless amphibian found throughout Brazil, has a concentration of enlarged mucous glands in its head region and a concentration of enlarged poison glands in its posterior region. These concentration appear to have evolved from different selective pressures: the ability to tunnel into the ground and to defend oneself from predators.  more...
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.  more...
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.  more...
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.  more...
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.  more...
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.  more...
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.  more...
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.  more...
