FDA Curb Antibiotics In Animal Foods
2013-12-11 13:18:30

Brett Smith for redOrbit.com - Your Universe Online The Food and Drug Administration (FDA) has issued guidelines calling on international pharmaceutical companies to phase out the production of antibiotics designed for use in animal production facilities. These drugs are often added to chicken or cow feed not to cure a sick animal, but to help them gain weight faster – a side-effect of the medications. In a statement, the FDA cited the growing concern of antibiotic resistant bacteria...

UMD psychologist, computer scientists use game theory to explain complex human behavior You're shopping for holiday gifts when you spot someone pocketing a nice pair of leather gloves. What do you do? A new study by University of Maryland researchers appearing this week in the Proceedings of the Royal Society B predicts that whether you alert a manager to the theft or decide to do nothing may depend on whether you're shopping in a local store where you know the owners or in a city far...

Advantage Held By Home Team
2013-12-10 08:59:08

Michigan State University The home team holds the advantage over visitors – at least in the plant world. However, a mere handful of genetic adaptations could even the playing field. In the current issue of the Proceedings for the National Academy of Sciences, Michigan State University researchers and their collaborators found that plant adaptation to different environments involves tradeoffs in performance. Genetic tradeoffs, in part, explain the rich diversity of species on earth....

Study Shows Impact Of Polyandry On Reproductive Success In Fire Salamanders
2013-12-02 16:11:27

University of Bielefeld Researchers at Bielefeld University and the Technische Universität Braunschweig are the first to confirm the benefit of multiple paternities for a vertebrate under completely natural conditions. Together with their team, Dr. Barbara Caspers and Dr. Sebastian Steinfartz have shown that female fire salamanders mate with several males under natural conditions (so-called polyandry). This grants them fitness-relevant benefits by increasing their number of offspring. The...

A team of Massachusetts General Hospital (MGH) investigators working to create "protocells" – primitive synthetic cells consisting of a nucleic acid strand encased within a membrane-bound compartment – have accomplished an important step towards their goal. In the November 28 issue of Science, the investigators describe a solution to what could have been a critical problem – the potential incompatibility between a chemical requirement of RNA copying and the stability of the protocell...

Extinction Event During End Of The Permian Period Likely Due To Acid Rain
2013-11-23 05:08:21

April Flowers for redOrbit.com - Your Universe Online At the end of the Permian period, approximately 250 million years ago, a mass extinction occurred that was so severe it remains the most traumatic known species die-off in Earth's history. Previous research has suggested that contemporaneous volcanic eruptions in Siberia might have triggered this extinction. A new study, published in the journal Geology, reveals that the atmospheric effects of these eruptions could have been...

Why do crosses between closely related species fail to produce fertile hybrids? A new study shows that differences in the levels - not necessarily the sequences - of certain key proteins are crucial in mediating reproductive isolation. Two individuals are defined as belonging to the same biological species, if matings between them give rise to viable and fertile offspring. Crosses between closely related, but already distinct, species produce hybrid offspring that are either inviable or...

An original model that would explain how regions of the genome that are copied later on facilitate the birth of new genes with specific functions in tissues and organs One of the most important processes in the life of cells is genome replication, which consists of making exact copies of the DNA in order to pass it on to their offspring when they split. In most organisms, from yeast to human beings, genome replication follows a set plan, in which certain regions of the genome replicate...

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...
