Policy update: Time dwindling to meet IDSA goal of 10 new antibiotics by 2020 Despite the desperate need for new antibiotics to combat increasingly deadly resistant bacteria, the U.S. Food and Drug Administration (FDA) has approved only one new systemic antibiotic since the Infectious Diseases Society of America (IDSA) launched its 10 x '20 Initiative in 2010 – and that drug was approved two and a half years ago. In a new report, published online today in Clinical Infectious...

BRIDGEWATER, N.J., April 18, 2013 /PRNewswire/ -- "The analysis released by the Environmental Working Group showing the bacterial contamination of the meat Americans buy in their supermarkets every day is a wake up call to the price of routinely feeding low doses of antibiotics to animals," said Stephen McDonnell, CEO and founder of Applegate, the nation's leading producer of natural and organic meat. "The price is a human health threat that we can no longer ignore." "Applegate supports...

FDA Finds Alarming Levels Of Antibiotic-Resistant Bacteria On Meat
2013-04-17 13:19:33

Brett Smith for redOrbit.com - Your Universe Online According to a new report from the Food and Drug Administration, shoppers who purchase meat may be getting more than they bargained for. In the newly released National Antimicrobial Resistance Monitoring System (NARMS) Retail Meat Annual Report, federal officials said their tests of retail meat revealed high levels of antibiotic resistant bacteria. According to the report, 87 percent of the meat the researchers tested contained...

20 to 40% of European plant and animal species endangered A new study on extinction risk based on extensive data from 7 taxonomic groups and 22 European countries has shown that proportions of plant and animal species being classified as threatened on national Red Lists are more closely related to socio-economic pressure levels from the beginning than from the end of the 20th century. Stefan Dullinger of the University of Vienna and Franz Essl from the Austrian Environment Agency together...

A University of Leeds-led study, published in the journal Ecology Letters, overturns the common assumption that evolution only occurs gradually over hundreds or thousands of years. Instead, researchers found significant genetically transmitted changes in laboratory populations of soil mites in just 15 generations, leading to a doubling of the age at which the mites reached adulthood and large changes in population size. The results have important implications in areas such as disease and...

3-year study offers new evidence about where scientists should be looking A structural biologist at the Florida State University College of Medicine has made discoveries that could lead scientists a step closer to understanding how life first emerged on Earth billions of years ago. Professor Michael Blaber and his team produced data supporting the idea that 10 amino acids believed to exist on Earth around 4 billion years ago were capable of forming foldable proteins in a high-salt...

New Genetic Study Of Tadpole Shrimps Casts Doubt On The Validity Of The Term 'Living Fossil'
2013-04-02 08:10:15

PeerJ The term 'living fossil' has a controversial history. For decades, scientists have argued about its usefulness as it appears to suggest that some organisms have stopped evolving. New research has now investigated the origin of tadpole shrimps, a group commonly regarded as 'living fossils' which includes the familiar Triops. The research reveals that living species of tadpole shrimp are much younger than the fossils they so much resemble, calling into question the term 'living...

Paternal Cues Heavily Influence Mate Choice In Mice
2013-03-28 16:35:39

Max-Planck-Gesellschaft Hybrid offspring of different house mice populations show a preference for mating with individuals from their father's original population Mate choice is a key factor in the evolution of new animal species. The choice of a specific mate can decisively influence the evolutionary development of a species. In mice, the attractiveness of a potential mate is conveyed by scent cues and ultrasonic vocalizations. Researchers from the Max Planck Institute for Evolutionary...

Researchers from Lund University and the University of Oxford have been able to provide one answer as to why males in many species still provide paternal care, even when their offspring may not belong to them. The study finds that, when the conditions are right, sticking around despite being 'cuckolded' actually turns out to be the most successful evolutionary strategy. The study, by Charlie Cornwallis and colleagues, is published 26 March in the open access journal PLOS Biology. In many...

Darwin’s Private Letters Reveal A Deeply Sensitive Side
2013-03-27 09:56:41

Brett Smith for redOrbit.com - Your Universe Online Charles Darwin is known primarily for his revolutionary theories on evolution and natural selection, but a series of soon-to-be-published letters show a personal, caring and emotional side of the iconic and controversial English naturalist. Some of the more intimate letters being released by Cambridge University´s Darwin Correspondence Project are a series of correspondences with his good friend and botanist Sir Joseph Hooker...

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...
