Assembling, Visualizing And Analyzing A Tree Of All Life
2012-06-06 03:42:53

National Science Foundation grants will bring together what's known about how species are related A new initiative aims to build a comprehensive tree of life that brings together everything scientists know about how all species are related, from the tiniest bacteria to the tallest tree. Researchers are working to provide the infrastructure and computational tools to enable automatic updating of the tree of life, as well as develop the analytical and visualization tools to study it....

Researchers Complete Mollusk Evolutionary Tree
2011-10-27 04:47:06

Mollusks have been around for so long (at least 500 million years), are so prevalent on land and in water (from backyard gardens to the deep ocean), and are so valuable to people (clam chowder, oysters on the half shell) that one might assume scientists had learned everything about them. “Here´s this big, diverse group of animals, and we don´t know how they were related to each other,” said Casey Dunn, an evolutionary biologist at Brown University who specializes in...

New tool to stop disease outbreaks and inform national security Pathogens can now be easily tracked in time and space as they evolve, an advance that could revolutionize both public health and inform national security in the fight against infectious diseases. Developed by researchers that include scientists at the American Museum of Natural History, Supramap (supramap.osu.edu) is a new, powerful, web-based application that maps genetic mutations like those among the different strains of avian...

New evidence that specialized adaptations are not evolutionary dead ends Blind scorpions that live in the stygian depths of caves are throwing light on a long-held assumption that specialized adaptations are irreversible evolutionary dead-ends. According to a new phylogenetic analysis of the family Typhlochactidae, scorpions currently living closer to the surface (under stones and in leaf litter) evolved independently on more than one occasion from ancestors adapted to life further below the...

New methods of studying avian influenza strains and visually mapping their movement around the world will help scientists more quickly learn the behavior of the pandemic H1N1 flu virus, Ohio State University researchers say. The researchers linked many powerful computer systems together to analyze enormous amounts of genetic data collected from all publicly available isolated strains of the H5N1 virus "“ the cause of avian flu. They then developed a new Web-based application that will...

In the most computationally intensive phylogenetic analysis to date, an international research team led by Brown University has found the first evolutionary branching for bilateral animals. The researchers determined that the flatworm group Acoelomorpha is a product of the deepest split within the bilateral creatures "” multicelled organisms that, like humans, have symmetrical body forms. Results appear online in Proceedings of the Royal Society B. When it comes to understanding a...

By Manos, Paul S Soltis, Pamela S; Soltis, Douglas E; Manchester, Steven R; Et al Abstract.- It is widely acknowledged that integrating fossils into data sets of extant taxa is imperative for proper placement of fossils, resolution of relationships, and a better understanding of character evolution. The importance of this process has been further magnified because of the crucial role of fossils in dating divergence times. Outstanding issues remain, including appropriate methods to place...

By Yesson, C; Culham, A Abstract.- We investigate the impact of past climates on plant diversification by tracking the "footprint" of climate change on a phylogenetic tree. Diversity within the cosmopolitan carnivorous plant genus Drosera (Droseraceae) is focused within Mediterranean climate regions. We explore whether this diversity is temporally linked to Mediterranean-type climatic shifts of the mid-Miocene and whether climate preferences are conservative over phylogenetic timescales....


Word of the Day
barratry
  • The offense of persistently instigating lawsuits, typically groundless ones.
  • An unlawful breach of duty on the part of a ship's master or crew resulting in injury to the ship's owner.
  • Sale or purchase of positions in church or state.
This word ultimately comes from the Old French word 'barater,' to cheat.
