Science Refutes Creationism

Rapidly weakening gene pool is a hard evidence against evolution http://genetics.thetech.org/weakened-gene-pool Excerpt: "A new review in GENETICS explains this potential problem pretty well. It has to do with DNA changes or mutations that pop up in each generation. And the loss of the ability to weed out the ones with minor, negative effects. Over time, these minor mutations might build up and have serious consequences. Left unchecked, our DNA might decline in quality, generation after generation. Now that isn’t to say that this article says that DNA quality is only going to go downhill. With screening and maybe even fixing broken genes (gene editing), we may eventually lose really bad mutations from the gene pool. So future generations may not get as many deadly genetic diseases as we do today. But it is the mutations that just cause minor problems that are, well, potentially the problem. We will not be able to easily find and screen for these. And combined they may have real co...

Eight a day is clearly best for your heart http://sciencenordic.com/eight-day-clearly-best-your-heart You’ve heard it a thousand times, that little catchphrase with the magic number encouraging you to eat “five a day” of fruits and vegetables for better health. But it turns out that the real magic number is eight, according to a new comprehensive study. The study, published in the International Journal of Epidemiology, spearheaded by Dagfinn Aune from NTNU and Imperial College London, shows that 7.8 million deaths worldwide could be prevented each year if people ate more fruits and vegetables. Aune says the more you eat, the lower the overall risk of heart disease, stroke, cancer and premature death. “The results support recommendations to increase the amount of fruits and vegetables people eat,” said Aune. The study shows that the risk of dying prematurely from all causes was reduced by almost a third, and the risk of cardiovascular disease by about a quarter in people who ate 800 gra...

Why we can only observe chromosome loss - not increase in chromosome numbers? We can pick and study any evolutionary tree of any diploid organism and make an obvious observation: Chromosomes are typically lost when so-called speciation occurs. Lets's have an example, the Fox lineage: Bat-eared fox 72 chromosomes Gray Fox 66 chromosomes Fennec Fox 64 chromosomes Bengal Fox 60 chromosomes Kit Fox 50 chromosomes Tibetan sand fox 36 chromosomes Red Fox 34 chromosomes And here's the phyloge netic tree of the Foxes and their assumed 'evolution': Have you ever asked the most important question:  Why we can only observe chromosome loss but not increase in chromosome numbers? The reason for chromosome loss can be found in epigenetic factors. Here's a brief summary. 1. Poor diet, stress and other environmental factors alter the epigenetic layers. Aberrant methylation patterns trigger sequen...

How epigenetics let scientists make giant ants https://www.labroots.com/trending/genetics-and-genomics/2578/epigenetics-scientists-giant-ants Excerpt: "Until now scientists have believed the variations in traits that exist along a continuum—height, skin color, tendency to gain weight or not, intelligence, tendency to develop certain diseases, etc.—come from both genetic and environmental factors. But they didn’t know how exactly these things worked together. By studying ants, researchers have identified a key mechanism by which environmental (or epigenetic) factors influence the expression of all of these traits, as well as many more. It’s a bit like an artist adding more or less white paint to black to create a palette of shades of gray. In effect, the study identifies the mechanism through which the environment interacts with specific genes, revealing environmental factors as an equal partner in determining complex traits. “It’s a discovery that completely changes our understand...

A DNA computer could potentially utilize more processors than all the electronic computers in the world combined https://phys.org/news/2017-03-scientists-reveal-super-fast.html Excerpt: "Researchers from The University of Manchester have shown it is possible to build a new super-fast form of computer that "grows as it computes". Professor Ross D King and his team have demonstrated for the first time the feasibility of engineering a nondeterministic universal Turing machine (NUTM), and their research is to be published in the prestigious Journal of the Royal Society Interface. The theoretical properties of such a computing machine, including its exponential boost in speed over electronic and quantum computers, have been well understood for many years – but the Manchester breakthrough demonstrates that it is actually possible to physically create a NUTM using DNA molecules. "Imagine a computer is searching a maze and comes to a choice point, one path leading left, the...

Fasting diet 'regenerates diabetic pancreas' http://www.bbc.com/news/health-39070183 Excerpt: "The pancreas can be triggered to regenerate itself through a type of fasting diet, say US researchers. Restoring the function of the organ - which helps control blood sugar levels - reversed symptoms of diabetes in animal experiments. The study, published in the journal Cell, says the diet reboots the body. Experts said the findings were "potentially very exciting" as they could become a new treatment for the disease. People are advised not to try this without medical advice. In the experiments, mice were put on a modified form of the "fasting-mimicking diet". It is like the human form of the diet when people spend five days on a low-calorie, low-protein, low-carbohydrate but high unsaturated-fat diet. It resembles a vegan diet with nuts and soups, but with around 800 to 1,100 calories a day. Then they have 25 days eating what they want - so overall it mimics ...

Early-stage embryos with abnormalities can still develop into healthy babies http://www.sanger.ac.uk/news/view/early-stage-embryos-abnormalities-can-still-develop-healthy-babies Excerpt: "Abnormal cells in the early embryo are not necessarily a sign that a baby will be born with a birth defect such as Down’s syndrome, suggests new research from the University of Cambridge, the Wellcome Trust Sanger Institute and the University of Leuven, Belgium. In a study published today (29 March) in the journal Nature Communications, scientists show that abnormal cells are eliminated and replaced by healthy cells, repairing – and in many cases completely fixing – the embryo. Researchers at the Department of Physiology, Development and Neuroscience at Cambridge report a mouse model of aneuploidy, where some cells in the embryo contain an abnormal number of chromosomes. Normally, each cell in the human embryo should contain 23 pairs of chromosomes (22 pairs of chromosomes and one pair of sex chr...
