Everyone knows the dismal statistics: 3/5 small businesses fail within 5 years. It´s not that these entrepreneurs don´t have the drive or the passion to succeed. Rather, it´s that they aren´t well-versed on the secrets to success or the common pitfalls that consume so many fitness businesses. Fitness Concepts CEO Sam Bakhtiar and his network of Millionaire Personal Trainers share their wealth of knowledge at http://www.Super-Trainer.com, a new fitness marketing blog...

Where´s the white hot furnace that powers evolution? For Darwin it lay in natural selection. The “Modern Synthesis” relocated it to genetic mutation. In the third of a series of articles published at http://www.takeondarwin.com, Contrarian Evolutionist author Shaun Johnston relocates it once again, to wherever variations in living creatures are created. (PRWEB) July 16, 2012 Modern evolutionary theory is the opposite of what people assumed when they first wondered what made...

Rare Glimpse Shows Origin Of Species

Plant overcomes infertility to give rise to a new species in Scotland A new species of monkey flower, created by the union of two foreign plant species, has been discovered on the bank of a stream in Scotland. Genetic changes in this attractive yellow-flowered hybrid have allowed it to overcome infertility and made it a rare example of a brand new species that has originated in the wild in the last 150 years. Thousands of wild species and some crops are thought to have originated in this...

Two Fused Species Give Rise To Plant Pest

A fungal species native to Iran which attacks grasses is the result of natural hybridisation that occurred just a few hundred years ago Zymoseptoria tritici is often a headache for European farmers. This ascomycete originating from the Middle East attacks the leaves of wheat plants triggering "speckled leaf blotch", which can cut crop yields by up to 50 percent. Scientists from the Max Planck Institute for Terrestrial Microbiology in Marburg and Aarhus University in Denmark have now taken...

Changing tissue landscape and not necessarily accumulated oncogenic mutations drive cancer rates higher in the elderly Cancers are age-related, much more frequent in the old than in the young. A University of Colorado Cancer Center review published today in the journal Oncogene argues against the conventional wisdom that the accumulation of cancer-causing mutations leads to more cancer in older people, instead positing that it is the changing features of tissue in old age that promote...

Steve Moose, an associate professor of maize functional genomics at the University of Illinois and his graduate student Wes Barber think they may have discovered a new source of heterosis, or hybrid vigor, in maize. They have been looking at small RNAs (sRNAs), a class of double-stranded RNA molecules that are 20 to 25 nucleotides in length. “Hybrid vigor” refers to the increased vigor or general health, resistance to disease, and other superior qualities arising from the...

Frequency-dependent selection fosters the diversity of populations but does not always increase the average fitness of the population. Genetic diversity arises through the interplay of mutation, selection and genetic drift. In most scientific models, mutants have a fitness value which remains constant throughout. Based on this value, they compete with other types in the population and either die out or become established. However, evolutionary game theory considers constant fitness values...

A classic study from more than 60 years ago suggesting that males are more promiscuous and females more choosy in selecting mates may, in fact, be wrong, say life scientists who are the first to repeat the historic experiment using the same methods as the original. In 1948, English geneticist Angus John Bateman published a study showing that male fruit flies gain an evolutionary advantage from having multiple mates, while their female counterparts do not. Bateman's conclusions have...

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.
