Mike Stephenson, a partner with McNeely Stephenson Thopy & Harrold, says long-term care facilities must be a part of the solution to the increasing problem posed by antibiotic-resistant bacteria. Shelbyville, IN (PRWEB) September 27, 2013 A report released September 16, 2013, by the Centers for Disease Control (CDC), describes the threat posed by three antibiotic-resistant germs as “urgent.” Two of the three are especially prevalent in medical settings and nursing homes, adding...

Role Of Sperm Competition In Formation Of New Species Confirmed By Biologists
2013-09-27 08:09:16

Syracuse University 'Current Biology' article marks culmination of 6 years of research Female promiscuity—something that occurs in a majority of species, including humans—results in the ejaculates from two or more males overlapping within her reproductive tract. When this happens, sperm compete for fertilization of the female's eggs. In addition, the female has the opportunity to bias fertilization of her eggs in favor of one male's sperm over others. These processes,...

Male fruit flies like to have a variety of sexual partners, whereas females prefer to stick with the same mate – or move on to his brothers. An Oxford University study of mating preferences in fruit flies (Drosophila) has found that males and females respond to the sexual familiarity of potential mates in fundamentally different ways. While male fruit flies preferred to court an unknown female over their previous mate or her sisters, female fruit flies displayed a predilection for...

It is common for parents to influence mate choice — from arranged marriages to more subtle forms of persuasion — but they often disagree with their children about what makes a suitable partner. A new study has found an evolutionary explanation for why some parents try to control who their children pair up with. The study, involving a University of Bristol researcher and published today in the journal Evolution & Human Behavior, shows that this conflict over mate choice may be...

Saving energy is important for humans and animals alike when resources are limited. Scientists at the Research Institute of Wildlife Ecology of the University of Veterinary Medicine, Vienna, found out that although higher-ranked red deer gain privileged access to patches of food, they also have higher metabolic rates and thus use more energy. This can be a serious disadvantage in winter when red deer rely largely on their limited stored body fat to survive. Energy budget adjustments...

[ Watch the Video: Comets May Have Provided Earth The Building Blocks Of Life ] Lawrence LeBlond for redOrbit.com - Your Universe Online An international group of scientists has discovered that life on Earth may have been jump-started when icy comets bombarded the planet billions of years ago. Scientists from University College London, the University of Kent and Lawrence Livermore National Laboratory have published a paper, appearing on the Nature Geosciences website on September 15....

More needs to be done to change patients' views though A local low-cost information campaign mainly targeted at citizens and involving doctors and pharmacists can significantly decrease total antibiotic prescribing, finds a paper published today on bmj.com. The excessive use of antibiotics is associated with resistance to these drugs and an increasing threat to global health. Antibiotics are also often unnecessarily and inappropriately prescribed. This is an issue that has been...

Researchers have developed a new strategy for prescribing antibiotics that could reduce patient harm and help combat the rise in antibiotic resistance. A new study, which is due to be presented at the European Respiratory Society (ERS) Annual Congress in Barcelona tomorrow (11 September 2013), found that a new prescribing protocol could significant reduce potential misuse of antibiotics. The research followed over 500 patients with lower respiratory tract infections during the course 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...
