Humans spend greater than 90 percent of their time indoors, but we're never alone there. Bacteria and viruses, scientists estimate, make up half of the world's biomass–some 10 nonillion (1 followed by 31 zeros) microorganisms–and we most often meet them within enclosed spaces. So, that's where the modern microbe hunter often looks first. A new report issued by the National Institute of Standards and Technology (NIST) offers guidance to make the hunting more effective. A...

Darwin made adaptation to the environment the key property of evolved living creatures. That's all natural selection can do. But suppose the key property of living creatures is how independent of their environment they are. This is number 1 in a series of website articles casting doubt on the Modern Synthesis. Rosendale, NY (PRWEB) May 29, 2012 In Darwin's theory of natural selection the key concept is "adaptation to the environment." All natural selection could do was identify which...

End-Permian Crisis Recovery Took Earth 10 Million Years
2012-05-28 04:07:34

It took the Earth 10 million years to recover from a cataclysmic event that wiped out 90% of plant and animal life some 250 million years ago, according to new evidence presented Sunday in the journal Nature Geoscience. According to a press release detailing the research, Dr. Zhong-Qiang Chen of the China University of Geosciences in Wuhan and Professor Michael Benton from the University of Bristol discovered that biological recovery from what they dub "the greatest mass extinction of all...

UCLA-Tel Aviv University team models genetic variation in 2-D, 3-D space Understanding the genetic diversity within and between populations has important implications for studies of human disease and evolution. This includes identifying associations between genetic variants and disease, detecting genomic regions that have undergone positive selection and highlighting interesting aspects of human population history. Now, a team of researchers from the UCLA Henry Samueli School of...

A large survey of human genetic variation, published today in the online version of the journal Science, shows that rare genetic variants are not so rare after all and offers insights into human diseases. "I knew there would be rare variation but had no idea there would be so much of it," said the senior author of the research, John Novembre, an assistant professor of ecology and evolutionary biology and of bioinformatics at UCLA. A team of life scientists studied 202 genes in 14,002...

Researchers Find That Some Butterflies Share DNA

Brett Smith for RedOrbit.com Geneticists have made a startling breakthrough while sequencing the genome of a South American butterfly, according to a study published in the May 16 edition of Nature. More than 70 scientists from 9 different institutions were involved in the Heliconius Genome Consortium, which sequenced the entire genome of the Postman butterfly (Heliconius melpomene). They found that the insect and two other related species, Heliconius timareta and Heliconius elevatus,...

Landscape of cancer genes and mutational processes in breast cancer In a study published today in Nature, researchers describe nine new genes that drive the development of breast cancer. This takes the tally of all genes associated with breast cancer development to 40. The team examined all the genes in the genomes of 100 cases of breast cancer. The mutated cancer-causing genes were different in different cancer samples, indicating that breast cancer is genetically very diverse....

NEW YORK, May 14, 2012 /PRNewswire/ -- The Program for Evolutionary Dynamics at Harvard University, announced to The Jeffrey Epstein Foundation, its main sponsor, that its staff were closer to understanding the link between chemical kinetics and when life takes over. "Prelife morphs into life when replication occurs," Martin Novak asserted, Director of the Program for Evolutionary Dynamics and Professor of Mathematics and Biology at Harvard. "There are many attributes necessary for life," he...

Is The Possibly Of New Life Forms Really So Alien?
2012-05-09 07:44:18

The idea of discovering a new form of life has not only excited astronomers and astrobiologists for decades, but also the wider public. The notion that we are the only example of a successful life form in the galaxy has, for many, seemed like an unlikely statistic, as we discover more and more habitable planetary bodies and hear yet more evidence of life's ability to survive in extreme conditions. A new essay, published May 8 in the online, open-access journal PLoS Biology, examines what...

A basic tenet underpinning scientists' understanding of extinction is that more abundant species persist longer than their less abundant counterparts, but a new University of Georgia study reveals a much more complex relationship. A team of scientists analyzed more than 46,000 fossils from 52 sites and found that greater numbers did indeed help clam-like brachiopods survive the Ordovician extinction, which killed off approximately half of the Earth's life forms some 444 million years ago....

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...
