  • Racial Differences Are Real but no Cause for Discrimination

    "New analyses of the human genome establish that human evolution has been recent, copious and regional," writes Nicholas Wade in his recently published book, "A Troublesome Inheritance: Genes, Race and Human History." That sounds reasonable, and Wade, a science reporter and editor for many years at Nature and the New York Times, seems an unimpeachable source. But many well-meaning people will regard his words as provocative and even dangerous. For they fatally undermine the idea, widely shared by so-called progressives, that any apparent differences between groups of people are the product of nurture rather than nature, of social conditioning rather...

    Friday, 23 May 2014 Stuart Gary ABC New Australian research suggests Martian minerals may have formed from biological rather than geological origins. The findings, reported in the journal Geology, indicate the mineral stevensite, which is found on both Earth and Mars, can be created either in hot, highly alkaline volcanic lakes, or by mineralisation in living microbes. Stevensite is a magnesium-silicate mineral, used a Nubian beauty treatment for several centuries.

    Powerhouse of Scientists Refute Evolution, Part One by Brian Thomas, M.S. * In 2011, the “Biological Information: New Perspectives” conference was held in which 29 leading design scientists technically assessed critical aspects of Neo-Darwinian theory. This evolutionary theory holds that new biological information arises when mutations allow nature to select between organisms, and when it first appeared many scientists thought it was a brilliant idea. However, according to those participating in the 2011 conference, the theory has proven to be inadequate and now needs replacement. The participants’ major findings, published technically in 2013, were summarized and grouped into three major...

    The Guardian (UK) ^ | 5-9-2014 | Damian Carrington
    The mysterious vanishing of honeybees from hives can be directly linked to insectcide use, according to new research from Harvard University. The scientists showed that exposure to two neonicotinoids, the world's most widely used class of insecticide, lead to half the colonies studied dying, while none of the untreated colonies saw their bees disappear. "We demonstrated that neonicotinoids are highly likely to be responsible for triggering 'colony collapse disorder' in honeybee hives that were healthy prior to the arrival of winter," said Chensheng Lu, an expert on environmental exposure biology at Harvard School of Public Health and who led the...

The marital status of the baby's parents was the subject of a flurry of court filings up to a few days before her birth. Valeria Tanco and Sophy Jesty were wed in New York, a state that recognizes gay marriage, and moved to Tennessee, which does not. They are among scores of same-sex couples who, working with advocacy groups, have filed lawsuits to expand gay-marriage rights following a major...

    Since they arrived in the Great Lakes in the 1980s, two species of mussels the size of pistachios have spread to hundreds of lakes and rivers in 34 states and have done vast economic and ecological damage. These silent invaders, the quagga and zebra mussels, have disrupted ecosystems by devouring phytoplankton, the foundation of the aquatic food web, and have clogged the water intakes and pipes of cities and towns, power plants, factories and even irrigated golf courses.

    One of the most misleading headlines imaginable recently appeared over an opinion column published in USA Today. Tom Krattenmaker, a member of the paper’s Board of Contributors, set out to argue that there is no essential conflict between evolution and religious belief because the two are dealing with completely separate modes of knowing. Evolution, he argued, is simply “settled science” that requires no belief. Religion, on the other hand, is a faith system that is based in a totally different way of knowing—a form of knowing that requires belief and faith. The background to the column is the recent data...

    Travel back far enough in your genealogy, and you will run into a fish. Before about 370 million years ago, our ancestors were scaly creatures that lived in the sea, swimming with fins and using gills to get oxygen from the water. And then, over the course of millions of years, they began moving ashore, adapting to the terrestrial realm. They became tetrapods, a lineage that would eventually produce today’s amphibians, reptiles, birds, and mammals. As scientists have unearthed fossils from those early days, one lesson has come through ever more loud and clear: the transition was not a single...

    The National Oceanic and Atmospheric Administration has launched a review of whether it should take North Pacific humpback whales off the endangered species list. NOAA Fisheries is responding to a petition filed by a group of Hawaii fishermen saying the whale should no longer be classified as endangered because its population has steadily grown since the international community banned commercial whaling nearly 50 years ago. There are more than 21,000 humpback whales in the North Pacific, compared with about 1,400 in the mid-1960s.

    TORONTO – Theories abound as to why women go into menopause, but the latest hypothesis being put forward suggests it may be men — or specifically their preference for younger mates —that has led to women’s loss of fertility at a certain age. Researchers at McMaster University believe that over tens of thousands of years, a lack of reproduction among older women has given rise to menopause as an unintended result of evolutionary natural selection. Using computer modelling, the researchers found that over time, competition among men of all ages for younger mates left older females with much less chance...

These signatures include the size of the hippocampus — a string bean–shaped structure involved in making memories — and how connected the area was with other parts of the brain. The findings suggest that kids struggling with their math homework aren’t necessarily slacking off, says cognitive scientist David Geary of the University of Missouri in Columbia. “They just may not have as much brain region devoted to memory...

    Scientists at the Walter and Eliza Hall Institute have for the first time visualised the molecular changes in a critical cell death protein that force cells to die. The finding provides important insights into how cell death occurs, and could lead to new classes of medicines that control whether diseased cells live or die. Cell death, called apoptosis, is important for controlling the number of cells in the body. Defects in cell death have been linked to the development of diseases such as cancer and neurodegenerative conditions. Insufficient cell death can cause cancer by allowing cells to become immortal while...

But for many animals, virgin birth is far from a miraculous event. Researchers have discovered a growing number of species that reproduce without assistance from the opposite sex. Known formally as parthenogenesis, virgin birth occurs when an embryo develops from an unfertilized egg cell. The development of an embryo usually requires genetic material from sperm and egg, as well as a series of chemical changes sparked by fertilization. In...

    New study brings to light physiological, cognitive differences of political left and right From cable TV news pundits to red-meat speeches in Iowa and New Hampshire, our nation's deep political stereotypes are on full display: Conservatives paint self-indulgent liberals as insufferably absent on urgent national issues, while liberals say fear-mongering conservatives are fixated on exaggerated dangers to the country. A new study from the University of Nebraska-Lincoln suggests there are biological truths to such broad brushstrokes. In a series of experiments, researchers closely monitored physiological reactions and eye movements of study participants when shown combinations of both pleasant and unpleasant...

    PDF version Imagine a one-celled organism the size of a mango. It's not science fiction, but fact: scientists have cataloged dozens of giant one-celled creatures, around 4 inches (10 centimeters), in the deep abysses of the world's oceans. But recent exploration of the Mariana Trench has uncovered the deepest record yet of the one-celled behemoths, known as xenophyophores. Found at 6.6 miles beneath the ocean's surface, the xenophyophores beats the previous record by nearly two miles. The Mariana Trench xenophyophores were discovered by dropcams, developed by the Scripps Institution of Oceanography and National Geographic, which are unmanned HD cameras 'dropped'...

    Researchers say they have created the first ever animal with artificial information in its genetic code. The technique, they say, could give biologists "atom-by-atom control" over the molecules in living organisms. One expert the BBC spoke to agrees, saying the technique would be seized upon by "the entire biology community".The work by a Cambridge team, which used nematode worms, appears in the Journal of the American Chemical Society.The worms - from the species Caenorhabditis elegans - are 1mm long, with just a thousand cells in their transparent bodies.What makes the newly created animals different is that their genetic code has...

    In 2007, a little known creature called a tardigrade became the first animal to survive exposure to space. It prevailed over sub-zero temperatures, unrelenting solar winds and an oxygen-deprived space vacuum. On Monday, this microscopic cosmonaut has once again hitched a ride into space on the Nasa shuttle Endeavour. Its mission: to help scientists understand more about how this so-called "hardiest animal on Earth" can survive for short periods off it. Tardigrades join other microscopic organisms selected to be part of a project into extreme survival. Shuttle Endeavour Endeavour climbs into the sky on Monday Project Biokis is sponsored by...

    A genetics research group working in a lab in Kansas, has succeeded in creating a new species of lizard by mating two distinct species of North American Whiptails, both native to New Mexico. The offspring, all females are not only fertile, but can reproduce by laying eggs that don't need to be fertilized, which means, they actually clone themselves. Scientists have known for years that some species exist due to interspecies mating, the whiptail lizards have provided proof of that; they’ve been creating new species themselves for at least several hundred thousand years. What’s new is the process being manipulated...

    Scientists are reporting discovery of an environmentally friendly way to make a key industrial material -- used in products ranging from paints to diapers -- from a renewable raw material without touching the traditional pricey and increasingly scarce petroleum-based starting material. Their report on a new catalyst for making acrylic acid appears in ACS Catalysis.Weijie Ji, Chak-Tong Au, and colleagues note that acrylic acid is essential for making paints, adhesives, textiles, leather treatments, and hundreds of other products. Global demand for the colorless liquid totals about 4 million tons annually. Acrylic acid is typically made from propylene obtained from petroleum....
  • The Grand Pantomime: There Is No Such Thing as Same-Sex Marriage

    When a happy young couple says “I do,” their marriage is contingent on their performing a specific sexual act. If they want to make their marriage real, they must consummate it. And that means that the meaning of marriage lies in the possibility of procreation. A marriage unconsummated is not a marriage. It is nullified, as though the ceremony had never happened. To become real, a marriage requires the possibility of conception. It does not require conception. Failure to conceive has never been grounds for nullification. Older, presumably infertile, couples are allowed to marry because if they had performed the...

    Genetic researchers may have resolved a long-standing dispute by proving there are two species of African elephant.Savannah and forest elephants have been separated for at least three million years, they say, and are as distinct from each other as Asian elephants are from the extinct woolly mammoth. The researchers also made what they say are the first sequences of nuclear DNA from the extinct American mastodon. > "The divergence of the two species took place around the time of the divergence of the Asian elephant and woolly mammoths," said Michi Hofreiter, a specialist in ancient DNA at the UK's York...

    The White House on Thursday said the controversial field of synthetic biology, or manipulating the DNA of organisms to forge new life forms, poses limited risks and should be allowed to proceed. An expert panel convened by President Barack Obama advised vigilance and self-regulation as scientists seeks ways to create new organisms that could spark useful innovations in clean energy, pollution control and medicine. The Presidential Commission for the Study of Bioethical Issues "concluded that synthetic biology is capable of significant but limited achievements posing limited risks," it said in its first report. "Future developments may raise further objections, but...
