If the U.S. wants to keep its prominence as a world power and technological innovator in the 21st century, we need to work fast.
Two new horned dinosaurs have been named based on fossils collected from Alberta, Canada. Unescopceratops koppelhusae and Gryphoceratops morrisoni are new species from the Leptoceratopsidae horned dinosaur family. The herbivores lived during the Late Cretaceous, between 75 to 83 million years ago. The specimens are described in Cretaceous Research. “These dinosaurs fill important gaps in…
NASA concluded its Gravity Recovery and Interior Laboratory (GRAIL) moon mission by crashing two probes into the lunar surface — on purpose. The goal of the mission is to map the moon’s gravitational field. To do this, NASA launched two washing-machine-size probes to orbit the moon in September 2011. After both craft achieved orbit, they…
Astronomers may have, for the first time, directly imaged a planet still in the process of formation, gathering material from a debris disk surrounding its parent star. Author Metanexus Editors
Both high-valued diamond and low-prized graphite consist of exactly the same carbon atoms. The subtle but nevertheless important difference between the two materials is the geometrical configuration of their building blocks, with large consequences for their properties. There is no way any kind of material could be diamond and graphite at the same time. However,…
Drinking a moderate amount of alcohol can have an impact on the ability of brain cells to regenerate, according to new research. The study, published in the journal Neuroscience, suggests that even drinking a couple of glasses of wine each day could decrease the creation of adult brain cells by as much as 40%. Lead…
Two years of painstaking observation on the social interactions of a troop of free-ranging monkeys and an analysis of their family trees has found signs of natural selection affecting the behavior of the descendants. Rhesus macaques who had large, strong networks tended to be descendants of similarly social macaques, according to a Duke University team…
