Topical research report “Antibiotic Resistance 2013: The Antibiotics Development Pipeline and Strategies to Combat Antibiotic Resistance” worked out by Biopharm Reports has been recently published by Market Publishers Ltd. London, UK (PRWEB) October 25, 2013 To date, there is a vital necessity to create antibiotic therapies undermining resistance mechanisms in a more effective way. The number of new antibiotic approvals has declined by approximately 60% during the last decade....

Better Sex In Return For Nuptial Gifts
2013-10-24 13:41:15

[ Watch The Video: Male Spider Presents Gift Before Sex] Aarhus University A male spider that gives its selected female a nuptial gift is allowed to mate with her for a longer period of time and provide more sperm than a male that fails to come with a gift. If a male spider goes to the trouble of finding a good gift, wraps it up nicely in spider silk and offers it to a female he would like to mate, he has far better chances of fathering her offspring than if he skipped the present....

Washington University in St. Louis A range of examples suggests a lack of information about their fellows can favor cooperation and prevent conflict among animals — and even among genes For the Oct. 16 issue of Biology Letters, a special issue commemorating the 50th anniversary of W.D. Hamilton’s famous paper on kin selection, two Washington University in St. Louis biologists contributed an article describing intriguing exceptions to one of his predictions. The basic idea of...

Every case of cancer originates from changes in a person's genetic material (mutations). These usually occur as "somatic mutations" in individual cells during an individual's lifetime, rather than being inherited from a person's parents. "Over time, the original damaged cell accumulates additional mutations, and it is still largely unknown why," says Prof. Roland Eils, who leads bioinformatics departments both at DKFZ and Heidelberg University. By studying when and where mutations occur...

The unique genomic signature could serve as a research model for founding events Researchers at the Sainte-Justine University Hospital Center and University of Montreal have discovered that the genomic signature inherited by today's 6 million French Canadians from the first 8,500 French settlers who colonized New France some 400 years ago has gone through an unparalleled change in human history, in a remarkably short timescale. This unique signature could serve as an ideal model to study...

Lee Rannals for redOrbit.com - Your Universe Online Researchers writing in the journal JAMA Internal Medicine unnecessary antibiotics are still being  prescribed across the US. Brigham and Women's Hospital (BWH) researchers say they found a large discrepancy between outpatient visits requiring antibiotics and national prescribing rates. "We know that antibiotic prescribing, particularly to patients who are not likely to benefit from it, increases the prevalence of...

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,...

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...
