New Study Sheds Light On Animal Social Behavior
2014-03-06 15:04:31

University of Exeter A theoretical study led by the University of Exeter has shed new light on the conditions that lead to the evolution of spite or altruism in structured populations. Understanding the way in which social behaviors such as altruism – when animals benefit others at their own expense – develop is a long-standing problem that has generated thousands of articles and heated debates. Dr Florence Débarre of Biosciences at the University of Exeter led a study,...

Genome Analysis Reveals Origins Of Genetic Adaptations For High Altitude In Tibetans
2014-02-11 09:00:22

University of Chicago Medical Center Genetic adaptations for life at high elevations found in residents of the Tibetan plateau likely originated around 30,000 years ago in peoples related to contemporary Sherpa. These genes were passed on to more recent migrants from lower elevations via population mixing, and then amplified by natural selection in the modern Tibetan gene pool, according to a new study by scientists from the University of Chicago and Case Western Reserve University,...

When people see a skunk, the reaction usually is “Eww,” but when they see a group of meerkats peering around, they often think “Aww.” Why some animals use noxious scents while others live in social groups to defend themselves against predators is the question that biologists Tim Caro of the University of California, Davis and Theodore Stankowich of California State University, Long Beach  and sought to answer through a comprehensive analysis of predator-prey interactions among...

Females discern male mouse songs to avoid inbreeding Female mice prefer songs of mice that are different from their parents when selecting a mate, according to a study published February 5, 2014 in PLOS ONE by Akari Asaba from the Azabu University, Japan, and colleagues. Furthermore, these preferences may be shaped by early social experiences with their fathers. Many animals can learn the characteristics of a desirable mate when they are young, and this includes the ability to recognize...

Ever since the nineteenth century scientists have recognized that some regions contain more species than others, and that the tropics are richer in biodiversity than temperate regions. But why are there more species in the tropics? A new study publishing 28 January in the Open Access journal PLOS Biology scrutinizes most of the living mammalian species and reveals a two-fold mechanism; the rate at which mammals arose was higher in the tropics, and the rate at which they became extinct lower....

Infidelity Linked To Large Testicles

Yngve Vogt  - University of Oslo “We can be grateful to parasites, bacteria and viruses for our ability to have sex. Even though sexual reproduction is far less efficient than non-sexual, nearly all living organisms that you can observe in your environment are based on sexual reproduction. The most important function of sex is to reshuffle the genes in each mating. In this way, the immune system develops resistance to parasites, bacteria and viruses,” explains Petter Bøckman,...

Signed commitment letter in exam rooms lowered inappropriate antibiotic prescriptions for cold symptoms by nearly 20 percent, saving $70 million/year in drug costs alone Inappropriate antibiotic prescriptions are a major public health concern, costing millions of dollars in unnecessary health care costs annually and contributing to the problem of antibiotic-resistant bacteria. Still, despite widely accepted prescription guidelines, physicians continue to prescribe antibiotics for colds...

Researchers from the University of Southern Denmark have identified how a mutated protein can lead to holes in a protein sitting in a cell's membrane. Such holes cause high blood pressure, and the discovery can now lead to new and better medication for high blood pressure. High blood pressure can be caused by many things - one of them being a specific mutated protein. Now the researchers at University of Southern Denmark have found out exactly what unfortunate events in the human organism...

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...
