Signed commitment letter in exam rooms lowered inappropriate antibiotic prescriptions for cold symptoms by nearly 20 percent, saving $70 million/year in drug costs alone Inappropriate antibiotic prescriptions are a major public health concern, costing millions of dollars in unnecessary health care costs annually and contributing to the problem of antibiotic-resistant bacteria. Still, despite widely accepted prescription guidelines, physicians continue to prescribe antibiotics for colds...

Researchers from the University of Southern Denmark have identified how a mutated protein can lead to holes in a protein sitting in a cell's membrane. Such holes cause high blood pressure, and the discovery can now lead to new and better medication for high blood pressure. High blood pressure can be caused by many things - one of them being a specific mutated protein. Now the researchers at University of Southern Denmark have found out exactly what unfortunate events in the human organism...

The evolutionary path from unicellular life to multicellularity is varied, but all lead to complex organisms In the beginning there were single cells. Today, many millions of years later, most plants, animals, fungi, and algae are composed of multiple cells that work collaboratively as a single being. Despite the various ways these organisms achieved multicellularity, their conglomeration of cells operate cooperatively to consume energy, survive, and reproduce. But how did multicellularity...

Engineering Plus Evolutionary Analyses Used To Answer Natural Selection Questions
2014-01-24 14:45:08

University of Massachusetts at Amherst Introducing a new approach that combines evolutionary and engineering analyses to identify the targets of natural selection, researchers report in the current issue of Evolution that the new tool opens a way of discovering evidence for selection for biomechanical function in very diverse organisms and of reconstructing skull shapes in long-extinct ancestral species. Evolutionary biologist Elizabeth Dumont and mechanical engineer Ian Grosse at the...

Bigger Really Was Better For Early Prehistoric Life

[ Watch the Video: The Evolution of the World’s Oldest Fossil Communities ] University of Toronto A NASA research group featuring University of Toronto Mississauga professor Marc Laflamme has helped to explain why some prehistoric organisms evolved into larger animals. Laflamme, an assistant professor with the Department of Chemical and Physical Sciences, and his colleagues at the Massachusetts Institute of Technology Node of NASA's Astrobiology Institute suggest that height...

As mating season approaches, male animals are faced with a question that can make or break their chances at reproducing: does it pay to be a lover or a fighter? Or both? Researchers from The University of Manchester and Syracuse University in New York working with the University of Western Australia, found that where animals fall on the lover/fighter scale depends on how much they are able to ensure continued mating rights with females. In species where fighting for the right to mate...

Flies That Live With Their Brothers Are Gentler Lovers

University of Oxford Flies living with their brothers cause less harm to females during courting than those living with unrelated flies, say Oxford University scientists. The study, published this week in Nature, found that unrelated male flies compete more fiercely for females' attention than related flies, resulting in shorter lifespans for males and reduced fecundity for females. "In large populations brothers don't need to compete so much with each other for female attention...

Genes And Calls Reveal Greater Diversity Of Amazon Frog Species
2014-01-15 15:12:22

Pensoft Publishers Amazonian biodiversity has been studied for hundreds of years. Early explorers of Amazonian plants and animals included renowned naturalists of the stature of Alexander von Humboldt and A. R. Wallace. Despite this long history of exploration, new studies are resulting in the discovery of a large number of new species. The key of these discoveries lies in the use of advanced new tools for species detection. The study, published in the open access journal ZooKeys, found...

Single cell analysis captures a genomic phenomenon that fuels the complexity and diversity of living things A Ludwig Cancer Research study has uncovered a phenomenon that alters prevailing views of how the genome is expressed to make and sustain the life of mammals. Published in the journal Science, the paper helps explain why genetically identical animals are sometimes so different in their biology and appearance, and why some inherited disorders caused by a shared set of aberrant genes...

Press release from PLOS Computational Biology Scientists have demonstrated that organisms with greater complexity are more likely to evolve in complex environments, according to research published this week in PLOS Computational Biology. The researchers, based at École Polytechnique Fédérale de Lausanne and University of Vermont, created a programme that simulated the evolution of virtual creatures in a variety of landscapes. Each virtual organism was made using a particular form of...

John Harold Ostrom (February 18, 1928 – July 16, 2005) was an American Paleontologist who was greatly influential in the revival of scientific research on Dinosaurs. He is best known for demonstrating that Dinosaurs were less like contemporary reptiles but more closely related to large, flightless birds like the ostrich – a theory that holds its ground in the paleontological community to this day. John Ostrom was born and raised in Schenectady, New York. His father was a physician, and...

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.
