Given the chance, women are more likely than men to opt out of a request to give a charitable donation, a group of economists have found. The issue of which gender is more generous has been debated for years. A new field experiment conducted by scholars at the University of Chicago and University of California, Berkeley shows that when it´s easy to avoid making a donation, such as not responding to a door-to-door solicitor, women are less likely than men to give. The results of the...

Species Recovery Programs May Spread Antibiotic Resistant Genes To Wild Populations
2013-05-23 10:37:49

Public Library of Science Endangered brush-tail rock wallabies raised in captive breeding programs carry antibiotic resistance genes in their gut bacteria and may be able to transmit these genes into wild populations, according to research published May 22 in the open access journal PLOS ONE by Michelle Power and colleagues from Macquarie University in New South Wales, Australia. Brush-tail rock wallabies are currently being raised in species recovery programs and restored to the wild...

Rice computational study tracks E. coli cells´ regulatory mechanisms Environment is not the only factor in shaping regulatory patterns – and it might not even be the primary factor, according to a new Rice University study that looks at how cells´ protein networks relate to a bacteria´s genome. The Rice lab of computer scientist Luay Nakhleh reported in the Proceedings of the National Academy of Sciences that when environmental factors are eliminated from an...

Female Lovelorn Frogs Grab The Closest Male
2013-05-20 13:16:57

BioMed Central What lures a lady frog to her lover? Good looks, the sound of his voice, the size of his pad or none of the above? After weighing up their options, female strawberry poison frogs (Oophaga pumilio) bag the closest crooner they can, finds research in BioMed Central's open access journal Frontiers of Zoology. This seemingly short-sighted strategy turns out to be the optimal mate choice strategy for these colorful frogs. Males of the species congregate in the Costa Rican rain...

Ancient Fish Fossils Give Insight Into Evolutionary History Of Gobioid Order
2013-05-16 13:51:46

LMU Fish fossils that are about 23 million years old give unprecedented insight into the evolutionary history of the gobioid order, one of the most species-rich groups among the modern bony fishes. Researchers led by paleontologist Professor Bettina Reichenbacher from the Division of Paleontology and Geobiology at LMU´s Department of Earth and Environmental Sciences have completed a comprehensive analysis of fish fossils which they assign to the group of bony fishes that includes...

Are You My Daddy? Infidelity And Paternity In Reed Warblers
2013-05-16 12:05:08

University of Veterinary Medicine Vienna Many species pair for life, or so the story goes. In reality, there is quite a bit of cheating going on. Both male and female partners may have “affairs” outside the pair bond. In such cases, how is a male to know if the chicks he is feeding are really his? Depending on the species, males have different strategies. They may try to ensure paternity by increased surveillance and fighting off the competition, or by having more frequent sex...

Port-Wine Stain Birthmark And Sturge-Weber Syndrome Tied By Gene
2013-05-12 09:49:26

redOrbit Staff & Wire Reports — Your Universe Online Researchers from the Kennedy Krieger Institute in Maryland have discovered a genetic mutation they say is responsible for both port-wine stain birthmarks and a rare neurological condition known as Sturge-Weber Syndrome (SWS). According to The Telegraph, the birthmarks are caused by “abnormally dilated capillaries in the skin, which produce reddish to purplish discoloration.” Now the researchers have discovered...

It's In The Genes: Europeans Have Been One Big Family For Past Thousand Years
2013-05-08 07:34:50

Lawrence LeBlond for redOrbit.com - Your Universe Online If there is one thing you can say about families, it is the larger the better. And by looking at genetic data of people from Ireland to the Balkans, researchers have found that Europeans are one big family, and have been for the past thousand years. Graham Coop, a professor of evolution and ecology at UCDavis, and Peter Ralph, a professor at University of Southern California (USC), published a recent study of the genetics 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...
