Amphibians, Dinosaurs Were The New Large Predators After The Mass Extinction
2014-03-20 12:37:13

University of Zurich 252 million years ago the largest extinction event occurred at the end of the Permian age. It wiped out almost 90 percent of all life in water. So far researchers had assumed that the ecosystems gradually recovered from this catastrophe over a long stretch of eight to nine million years and that large predators at the uppermost end of the food chain were the last to reappear. A Swiss-American team of palaeontologists headed by Torsten Scheyer and Carlo Romano from the...

Sea Anemone genetics
2014-03-18 13:58:44

Lee Rannals for redOrbit.com - Your Universe Online Researchers lead by evolutionary and developmental biologist Ulrich Technau at the University of Vienna say that a sea anemone has a genomic landscape that is half animal, half plant. Developmental biologists found that the genetic landscape of sea anemones features complex regulatory elements similar to that of fruit flies or other animal model systems. However, they also discovered that sea anemones are more similar to plants rather...

Europeans' Appearance Altered Over Five Millennia Of Natural Selection

April Flowers for redOrbit.com - Your Universe Online A great deal of research has been focused on the factors that have influenced the human genome since the end of the last Ice Age. An international team of scientists—including anthropologists at Johannes Gutenberg University Mainz (JGU), geneticists at University College London (UCL), and archaeologists from Berlin and Kiev—has analyzed ancient DNA from skeletons, finding that natural selection has had a major effect on the human...

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....

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...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
