Top 10 New Species Announced By Scientists
2013-05-23 14:09:02

Arizona State University Researchers call for massive mission: discover 10 million species in 50 years An amazing glow-in-the-dark cockroach, a harp-shaped carnivorous sponge and the smallest vertebrate on Earth are just three of the newly discovered top 10 species selected by the International Institute for Species Exploration at Arizona State University. A global committee of taxonomists – scientists responsible for species exploration and classification – announced its...

Rice computational study tracks E. coli cells´ regulatory mechanisms Environment is not the only factor in shaping regulatory patterns – and it might not even be the primary factor, according to a new Rice University study that looks at how cells´ protein networks relate to a bacteria´s genome. The Rice lab of computer scientist Luay Nakhleh reported in the Proceedings of the National Academy of Sciences that when environmental factors are eliminated from an...

Evolution Of Hips Simpler Than Suspected
2013-05-15 12:04:37

April Flowers for redOrbit.com - Your Universe Online The evolutionary path from the bone structure of the fish to the complex, weight-bearing hips of walking animals was a much simpler process than previously thought, according to a new study. About 395 million years ago, the first tetrapods, or four-legged animals, stepped onto land. This transition was accomplished using strong, weight-bearing hipbones and a connection through the spine via the ilium. These features were not present...

Untangling The Branches Of The Tree Of Life
2013-05-15 10:33:57

Vanderbilt University These days, phylogeneticists — experts who painstakingly map the complex branches of the tree of life — suffer from an embarrassment of riches. The genomics revolution has given them mountains of DNA data that they can sift through to reconstruct the evolutionary history that connects all living beings. But the unprecedented quantity has also caused a serious problem: The trees produced by a number of well-supported studies have come to contradictory...

Study Proves Darwin's Theory That Productivity Increases Species Diversity
2013-05-14 06:49:07

April Flowers for redOrbit.com - Your Universe Online Charles Darwin predicted that a plot of land growing distantly related grasses would be more productive than a plot with a single species of grass in On The Origin of Species, first published in 1859. Over 150 years later, a new study from the University of Toronto Scarborough (UTSC), reveals Darwin was right; environments containing species that are distantly related to one another are more productive than those containing closely...

Cooperative behaviour is widely observed in nature, but there remains the possibility that so-called 'cheaters' can exploit the system, taking without giving, with uncertain consequences for the social unit as a whole. A new study has found that a yeast colony dominated by non-producers ('cheaters') is more likely to face extinction than one consisting entirely of producers ('co-operators'). The findings, published April 30 in the open access journal PLOS Biology by Alvaro Sanchez and Jeff...

A team of researchers at the University of Massachusetts Amherst is proposing a new investigative roadmap for the field of evolutionary developmental biology, or “evo devo,” to better understand how innovation at the genetic level can lead to ecological adaptations over time. Evo devo seeks to understand the specific genetic mechanisms underlying evolutionary change. Seven UMass Amherst authors, all biologists but with diverse research programs including evolutionary genetics,...

Algorithm Shows Evolution Of Soft Robots
2013-04-23 18:57:19

Lee Rannals for redOrbit.com — Your Universe Online A group of researchers from Cornell University's Creative Machines Lab say they have developed an algorithm that can be used to witness virtual creatures evolving. The team wrote in their paper titled "Unshackling Evolution: Evolving Soft Robots With Multiple Materials and a Powerful Generative Encoding" in the journal Proceedings of the Genetic and Evolutionary Computation Conference about their algorithm. They said the...

An international research team including Christian Schlötterer and Alistair McGregor of the Vetmeduni Vienna has discovered a completely new mechanism by which evolution can change the appearance of an organism.  The researchers found that the number of hairs on flies´ legs varies according to the level of activity of a so-called microRNA.  The results, published in the journal Current Biology, shed a completely new light on the molecular mechanisms of evolution....

Paleontology
2014-01-12 00:00:00

Paleontology or Palaeontology is the scientific study of prehistoric life, including the study of fossils to determine the organisms evolution and interactions with each other and their environments. Paleontological observations have been documented as far back as 5th century BC. The science became established in the 18th century as a result of Georges Cuvier’s work on comparative anatomy, and it developed quickly within the 19th century. The term itself comes from Greek palaios, meaning...

mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
