Cooperative behaviour is widely observed in nature, but there remains the possibility that so-called 'cheaters' can exploit the system, taking without giving, with uncertain consequences for the social unit as a whole. A new study has found that a yeast colony dominated by non-producers ('cheaters') is more likely to face extinction than one consisting entirely of producers ('co-operators'). The findings, published April 30 in the open access journal PLOS Biology by Alvaro Sanchez and Jeff...

A team of researchers at the University of Massachusetts Amherst is proposing a new investigative roadmap for the field of evolutionary developmental biology, or “evo devo,” to better understand how innovation at the genetic level can lead to ecological adaptations over time. Evo devo seeks to understand the specific genetic mechanisms underlying evolutionary change. Seven UMass Amherst authors, all biologists but with diverse research programs including evolutionary genetics,...

Giving prescribers access to education and advice or imposing restrictions on use can curb overuse or inappropriate use of antibiotics in hospitals, according to a new Cochrane systematic review. This is important because unnecessary use of these life-saving drugs is a key source of antibiotic resistance in bacteria. Some infections are no longer treatable due to bacterial resistance. Compared to infections caused by treatable bacteria, those caused by multidrug-resistant bacteria lead to...

Mass Extinction Made Space Dinosaur Forerunners

April Flowers for redOrbit.com - Your Universe Online Approximately 252 million years ago, during the world´s largest mass extinction event, nine out of ten species vanished from the planet. Based on fossil records from sites in South Africa and southwest Russia, many scientists have long thought the predecessors of dinosaurs largely missed the race to fill habitat niches that were emptied during this event. However, according to an international team of scientists, it turns out...

Sequencing of 57 prostate cancer genomes shows cancer gains powerful advantage with abrupt intervals of complex, large scale DNA reshuffling Cancer is typically thought to develop after genes gradually mutate over time, finally overwhelming the ability of a cell to control growth. But a new closer look at genomes in prostate cancer by an international team of researchers reveals that, in fact, genetic mutations occur in abrupt, periodic bursts, causing complex, large scale reshuffling of...

Not enough is being done to educate those living in border communities about the long-term effects of antibiotic overuse and misuse, South Texas scientist says When thousands of experimental biology researchers gather in Boston this weekend, many of them undoubtedly will be presenting work related to the hunt for the next generation of antibiotics and how to battle back existing and emerging superbugs. But for one scientist from Texas Rio Grande Valley, it's not about what the research of...

A new study concludes that problems with antibiotic resistance faced by outpatients may be as bad as those in hospitalized patients, and that more studies of outpatients are needed — both to protect their health and to avoid inappropriate or unnecessary drug use. Antibiotic resistance is a huge and growing problem in both hospital and outpatient settings. Failure to select an effective antibiotic, without appropriate consideration for this resistance, can increase the risk of...

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...

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...
