    Genetic Entropy Points to a Young Creation by Jeffrey Tomkins, Ph.D. * Many creationists believe that the bulk of scientific evidence for a recent creation comes from the fields of geology, physics, and astronomy and that biology and genetics have little to contribute. However, data that confirm a young creation are rapidly emerging from genetic studies performed by both creationist and secular scientists. One of the most important finds in recent years came from modeling the accumulation of mutations (genetic code errors) in the human genome over time using computer simulations. Researchers found that this buildup of mutations can only...

    Remember the sci-fi thriller GATTACA? For those who never saw the film and/or eschewed all pop culture in the late 90’s for some reason, it was a popular movie that came out in 1997 about genetically modified human beings. Now some literally genetically modified human babies born that same year are entering their senior year of high school. The first successful transfer of genetic material for this purpose was published in a U.S. medical journal in 1997 and then later cited in a Human Reproduction publication in 2001. Scientists injected 30 embryos in all with a third person’s genetic material....

Why we, Homo sapiens, flourished and our Homo neandertalensis cousins died out is an evolutionary mystery that biologist are trying to unravel. In the last few years, scientists have uncovered clues not just to what the lives of Neanderthals may have been like, but also clues that tell us more about...

    WASHINGTON (AP) -- The Food and Drug Administration says it approved a genetic test from Roche to help doctors identify patients who can benefit from a lung cancer drug made by Genentech. The diagnostic test is the first approved to detect genetic mutations found in roughly 10 percent of patients with the most prevalent form of lung cancer, known as non-small cell lung cancer. Patients who test positive for the mutation are more likely to respond to Genentech's drug Tarceva as a first-choice treatment, and the FDA expanded the drug's approval for that use in an announcement Tuesday. The drug...

Xaltocan was the capital of a pre-Aztec city-state ruled by the Otomi, an indigenous people who lived in Mexico. The period before the Aztec conquest was a tumultuous time for the Otomi, when a century of warfare led to the collapse of their capital city. Colonial records from the 1500s onward told tales of the Otomi fleeing the city en masse in 1395. Those records suggested that the city was abandoned...

    China usually holds its military hand very close to the vest--that, or things “mysteriously” leak that it doesn’t (does) want the world to know about--so we’re left to wonder why the People’s Republic has decided to publish this in the journal Advanced Materials Research. Nonetheless, it’s pretty interesting. Chinese navy researchers have plans for a new submarine hunting scheme that uses ship-launched UAVs running genetic algorithms. Genetic algorithms narrow down a range of possibilities to an optimal solution much the way evolution does (at least in a simplified sense)--by weeding out the weaker offspring and mating the best with the...

Data on genetics, morphology and behaviour show clearly that dogs are descended from wolves, but there’s never been scientific consensus on...

    Twenty-one college football players have collapsed and died as a result of training over the past decade. At least eight were carriers of the sickle-cell trait, a genetic disorder that can unpredictably turn deadly during rigorous exercise. A blood test to screen for the trait costs about $5, and many university team doctors and athletic trainers support compulsory testing, arguing that it could save lives. Yet a proposal to make such testing mandatory for all N.C.A.A. Division I athletes is not a sure bet to pass when it comes up for a vote by member conferences as early as Monday...

    ScienceDaily: “Slowing Evolution to Stop Drug Resistance” --snip-- For years, evolutionists have pointed to antibiotic resistance as proof of evolution in action. The argument often amounts to this (in simplified form): the fact that certain organisms grow resistant to certain antibiotics is evidence for the evolutionary idea that all animals must have descended from a single ancestor. Collapsing the argument does make it seem a bit silly, but that’s our point. We certainly don’t want to belittle the very real threat of dangerous organisms becoming immune to the best drugs we now have (though the vast majority of microbes are...

    The world's largest cat, the Amur tiger, is down to an effective wild population of fewer than 35 individuals, new research has found. Although up to 500 of the big cats actually survive in the wild, the effective population is a measure of their genetic diversity. That in turn is a good predictor of the Amur tiger's chances of survival. The results come from the most complete genetic survey yet of wild Amur tigers, the rarest subspecies of tiger.

The four dogs, all named "Ruppy" — a combination of the words "ruby" and "puppy" — look like typical beagles by daylight. But they glow red under ultraviolet light, and the dogs' nails and abdomens, which have thin skins, look red even to the naked eye.

European and US scientists have proved for the first time that two bits of genetic coding, called nucleobases, contained in the meteor fragment, are truly extraterrestrial.

    Not one but 'six giraffe species' Anna-Marie Lever Science and nature reporter, BBC News Giraffe populations have dropped by 30% over the past decade The world's tallest animal, the giraffe, may actually be several species, a study has found. A report in BMC Biology uses genetic evidence to show that there may be at least six species of giraffe in Africa. Currently giraffes are considered to represent a single species classified into multiple subspecies. The study shows geographic variation in hair coat colour is evident across the giraffe's range in sub-Saharan Africa, suggesting reproductive isolation. "Using molecular techniques we found...

    Environment can change the way our genes work Environmental factors such as stress and diet could be affecting the genes of future generations leading to increased rates of obesity, heart disease and diabetes.A study of people suffering post-traumatic stress disorder (PTSD) after the 9/11 attacks in New York made a striking discovery. The patients included mothers who were pregnant on 9/11 and found altered levels of the stress hormone cortisol in the blood of their babies. This effect was most pronounced for mothers who were in the third trimester of pregnancy suggesting events in the womb might be responsible....

    A pet store has bought a two-headed turtle from a collector and plans to keep it on display, the store manager said. The 2-month-old turtle, actually conjoined red-eared slider twins, fits on a silver dollar. It has two heads sticking out from opposite ends of its shell, along with a pair of front feet on each side. But there is just one set of back feet and one tail. The turtle is apparently healthy, and the species can live 15 to 20 years, said Jay Jacoby, manager of Big Al's Aquarium Supercenter in East Norriton. The turtle has not...

    Source: Blackwell Publishing Ltd. Date: August 31, 2007 Disease Resistance May Be Genetic Science Daily — According to a study in Evolution, resistance to certain infectious diseases may be passed genetically from parent to child. The genetic resistance may be beneficial to families as those with the gene are both unlikely to suffer from disease and unlikely to carry the disease home. Paul Schliekelman, author of the study, says the research was inspired by personal experience after catching stomach flus from his daughter three times over a six-month period. Schliekelman used mathematical models to calculate the possible effect of “kin...

    When it reportedly happened in Morocco five years ago, locals feared it signaled the end of the world. In Albania in 1994, it was thought to have unleashed the spawn of the devil on a small village. But on a Grand Mesa ranch, the once-in-a-million, genetically "impossible" occurrence of a mule giving birth has only drawn keen interest from the scientific world. That, and a stream of the locally curious driving up from the small town of Collbran to check out and snap pictures of a frisky, huge-eared, gangly legged foal. "No one has run away in fear yet," laughed...

    Black Death casts a genetic shadow over England 12:26 01 August 2007 NewScientist.com news service Colin BarrasBlack Death as illustrated in a 15th century bible The Black Death continues to cast a shadow across England. Although the modern English population is more cosmopolitan than ever, the plagues known as the Black Death killed so many people in the Middle Ages that, to this day, genetic diversity is lower in England than it was in the 11th century, according to a new analysis. Rus Hoelzel at the University of Durham, UK and his colleagues looked at the mitochondrial DNA from human...

    Norwegian arhaeologists are puzzled by a find which indicates an Inca Indian died and was buried in the Oestfold city of Sarpsborg 1000 years ago. The remains of two elderly men and a baby were discovered during work in a garden, and one of the skulls indicates that the man was an Inca Indian. There is a genetic flaw in the neck, which is believed to be limited to the Incas in Peru, says archaeologist Mona Beate Buckholm. The Norway Post suggests that maybe the Vikings travelled even more widely than hitherto believed? Why could not the Viking settlers in...

    The researchers hope to scale the work up to the whole of the genome A close-up view of the human genome has revealed its innermost workings to be far more complex than first thought.The study, which was carried out on just 1% of our DNA code, challenges the view that genes are the main players in driving our biochemistry. Instead, it suggests genes, so called junk DNA and other elements, together weave an intricate control network. The work, published in the journals Nature and Genome Research, is to be scaled up to the rest of the genome. Views transformed...

    'Give genetic test secrets to insurers' By Nicole Martin Last Updated: 1:58am BST 08/06/2007 The results of genetic tests should be passed on to insurance companies to allow them to assess the health risks of potential customers, a professor of bioethics says today. Prof Soren Holm, from Cardiff University Law School, says that genetic information is no more "sensitive or private" than other information about a person's health, including cholesterol levels and body mass index, which insurers can use to help them to set premiums. His recommendation was immediately rejected by health charities. They said greater openness could lead to...

    Genetic roots of manic depression revealed By Roger Highfield, Science Editor Last Updated: 2:24am BST 08/05/2007 The genetic roots of bipolar disorder - manic depression - have been revealed by the first scan of the entire human genetic code, revealing a new target for treatments. Bipolar disorder affects one person in every 100 inducing mood changes from extremes of depression to irritation, elation and mania. However, the likelihood of developing the disorder, which usually occurs in young adults, depends in part on the combined, small effects of variations in many different genes in the brain, none of which is powerful...
