    Elizabeth Palermo September 15, 2015An artist's depiction of the dual meteor strike. (Don Dixon/Erik Sturkell/University of Gothenburg) It's not altogether uncommon to hear about double rainbows, but what about a double meteor strike? It's a rare event, but researchers in Sweden recently found evidence that two meteors smacked into Earth at the same time, about 458 million years ago. Researchers from the University of Gothenburg uncovered two craters in the county of Jämtland in central Sweden. The meteors that formed the craters landed just a few miles from each other at the same moment, according to Erik Sturkell, a professor...

    The earliest life on Earth might have been just as purple as it is green today, a scientist claims. Ancient microbes might have used a molecule other than chlorophyll to harness the Sun’s rays, one that gave the organisms a violet hue. Chlorophyll, the main photosynthetic pigment of plants, absorbs mainly blue and red wavelengths from the Sun and reflects green ones, and it is this reflected light that gives plants their leafy color. This fact puzzles some biologists because the sun transmits most of its energy in the green part of the visible spectrum. “Why would chlorophyll have this...

    Ancient_antarctic_microbes_2_2 The unusual properties of frozen water may have been the ticket that made life possible. Over the decades, several notable scientists have began to suspect that life on Earth did not evolve in a warm primordial soup, but in ice—at temperatures that few living things can now tolerate. The very laws of chemistry may have actually favored ice, says Jeffrey Bada, at the Scripps Institution of Oceanography in La Jolla, California. “We’ve been arguing for a long time,” he says, “that cold conditions make much more sense, chemically, than warm conditions.” If Bada and others are correct, it would...

    "Isn't life wonderful?" sang Alma Cogan and Les Howard in their almost forgotten 1953 hit. That same year, Stanley L. Miller raised the hopes of understanding the origin of life when on 15 May, Science published his paper on the synthesis of amino acids under conditions that simulated primitive Earth's atmosphere (1). Miller had applied an electric discharge to a mixture of CH4, NH3, H2O, and H2--believed at the time to be the atmospheric composition of early Earth. Surprisingly, the products were not a random mixture of organic molecules, but rather a relatively small number of biochemically significant compounds such...

    Washington, Oct 06: A meteorite, which crashed into Australia 40 years ago, is telling researchers new things about how life may have started on Earth, and how that almost universal protein left-handedness came to be. For more than 150 years, scientists have known that the most basic building blocks of life - chains of amino acid molecules and the proteins they form - almost always have the unusual characteristic of being overwhelmingly “left-handed.” The molecules, of course, have no hands, but they are almost all asymmetrical in a way that parallels left-handedness. This observation, first made in the 1800s by...

    Full title: Ancient bubbles in Australian rocks show early Earth's air weighed less than half today's atmosphere Air bubbles trapped in 2.7 billion-year-old Australian rock suggest the Earth's atmosphere weighed less than half of today and was much thinner than previously thought. Researchers analysed the size of air bubbles that formed at the top and bottom of lava flows along the Beasley River in Western Australia's Pilbara region almost three billion years ago and used the data to calculate the atmospheric pressure at the time. The results suggest that the air at the time exerted at most half the pressure...

In 1953, Stanley L. Miller, then a graduate student of Harold C. Urey at the University of Chicago, put ammonia, methane and hydrogen — the gases believed to be in early Earth’s atmosphere — along with water in a sealed flask and applied electrical sparks to simulate the effects of lightning. A week later, amino acids, the building blocks of proteins, were generated out of the simple molecules. Enshrined in...

    The question about the origin of oceans on Earth is one of the most important questions with respect to the formation of our planet and the origin of life. The most popular theory is that water was brought by impacts of comets and asteroids. Data from the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis (ROSINA) instrument aboard the European Space Agency’s Rosetta spacecraft indicate that terrestrial water did not come from comets like 67P/Churyumov-Gerasimenko.

    Evidence is mounting that the time-weathered red planet was once a warm and water-rich world. And a Mars awash with water gives rise to that globe possibly being fit for habitation in its past – and perhaps a distant dwelling for life today. As sensor-laden orbiters circle the planet, NASA’s twin Mars rovers -- Spirit and Opportunity -- have been tooling about and carrying out exhaustive ground studies for nearly a year. The Opportunity robot at Meridiani Planum, for instance, has found telltale signs that water came and went repeatedly within that stretch of Martian real estate. While that intermittent...

But Paul Knauth, an astrobiologist with Arizona State University, says while we always assume that life came from the ocean, this theory has never been proven. He suggests we need to consider the possibility that life originated in fresh water.The next time you reach for that bag of salty chips, think for a moment about salt and life. Humans need a certain amount of salt; it is necessary for the delivery of nutrients, the transmission...

    Given the reality of the dark spots, which soon became known as "atmospheric holes" because of their appearance in the images, there is only one explanation which has endured over all these years to present. That is, the holes are due to the shadowing of the atmospheric light by an object above the atmosphere. This object simply cannot be a stony or iron meteor because the holes are very large, tens of miles in diameter. A rock of this size would provide a disastrous impact on the Earth's surface. As it turns out, water vapor is very good at absorbing...

    Most scientists have long assumed that life on Earth is a homegrown phenomenon. According to the conventional hypothesis, the earliest living cells emerged as a result of chemical evolution on our planet billions of years ago in a process called abiogenesis. The alternative possibility--that living cells or their precursors arrived from space--strikes many people as science fiction. Developments over the past decade, however, have given new credibility to the idea that Earth's biosphere could have arisen from an extraterrestrial seed. Planetary scientists have learned that early in its history our solar system could have included many worlds with liquid water,...

A study using the Herschel space telescope aimed to measure the quantity of deuterium, a rare type of hydrogen, present in the comet's water. The comet had just half the amount of deuterium seen in comets. The result, published in Nature, hints at the idea that much of the Earth's water could have initially came from cometary impacts. Just a few million years after its formation, the early Earth was rocky and dry; something must have brought the water that covers...

    Scientists have long believed that comets and, or a type of very primitive meteorite called carbonaceous chondrites were the sources of early Earth's volatile elements -- which include hydrogen, nitrogen, and carbon -- and possibly organic material, too. Understanding where these volatiles came from is crucial for determining the origins of both water and life on the planet. New research led by Carnegie's Conel Alexander focuses on frozen water that was distributed throughout much of the early Solar System, but probably not in the materials that aggregated to initially form Earth...

Therefore, abiogenesis (i.e., life arising from non-living materials) is impossible, according to the scientific evidence. How then can atheistic theories like Darwinian evolution be considered acceptable? There is a growing trend among evolutionists today to attempt to sidestep the problem of abiogenesis by contending that evolution has nothing to do with the origin of life, but rather is a theory which starts with life already in existence and explains the origin of all species from that original life form....

Today the 'soup' theory has been over turned in a pioneering paper in BioEssays which claims it was the Earth's chemical energy, from hydrothermal vents on the ocean floor, which kick-started early life. "Textbooks have it that life arose from organic soup and that the first cells grew by fermenting these organics to generate energy in the form of ATP. We provide a new perspective on why that old and familiar view...

    Evolutionists retreating from the arena of science --snip-- Today, the Darwinian scientific consensus persists within almost every large university and governmental institution. But around the middle of the 20th century an interesting new trend emerged and has since become increasingly established. Evolutionary theorists have been forced, step by step, to steadily retreat from the evidence in the field. Some of the evidences mentioned earlier in this article were demonstrated to be frauds and hoaxes. Other discoveries have been a blow to the straightforward expectations and predictions of evolutionists. Increasingly, they have been forced to tack ad hoc mechanisms onto Darwin’s...

    HUNTSVILLE, AL, Nov. 25 Christian Newswire -- Two creation films called "inappropriate" were denied the opportunity to be shown in government facilities this week--which marks the 150th anniversary of the publication of Charles Darwin's "Origin of Species". While the intelligent design film "Darwin's Dilemma: The Mystery of the Cambrian Fossil Record" has not been granted permission for a showing in California, "The Mysterious Islands", a new 90-minute Vision Forum film that challenges Darwin's evolution by taking audiences back to engage the enchanted Galapagos Islands, has enjoyed a victory and will premiere as previously scheduled tonight, Nov. 25, at 6:30 PM, at...

    More details are now coming out from the lawsuit filed against the California Science Center by the American Freedom Alliance (AFA), filed in the Superior Court for the State of California for the County of Los Angeles (Central District). AFA's lawsuit contends that the California Science Center engaged in viewpoint discrimination when cancelling AFA's contract to screen the pro-intelligent design (ID) documentary Darwin’s Dilemma at the Center’s IMAX Theatre on October 25th. As discussed below, AFA's complaint contains e-mails from California Science Center staff revealing that the Center cared more about how it would be perceived by ID-critics in the...

    Pro-Darwin consensus doesn't rule out intelligent design --snip-- (CNN) -- While we officially celebrate the 150th anniversary of the publication of Charles Darwin's "On the Origin of Species" on November 24, celebrations of Darwin's legacy have actually been building in intensity for several years. Darwin is not just an important 19th century scientific thinker. Increasingly, he is a cultural icon. Darwin is the subject of adulation that teeters on the edge of hero worship, expressed in everything from scholarly seminars and lecture series to best-selling new atheist tracts like those by Richard Dawkins and Christopher Hitchens. The atheists claim that...

    Today, November 24, it is exactly 150 years since Charles Darwin published his On the Origin of Species. The world has been gearing up for this “second echelon” of celebrations for this international “Year of Darwin”, following on from the 200th anniversary of his birth this last February. Atheists and humanist groups in particular have seemed to be relishing the thought of giving further prominence to the ideas of their patron saint. Their adulation is heightened by their knowledge that...

    It has always amazed me how unconcerned evolutionists seem to be about entropy and the problems it poses both for a natural origin of life and for macroevolution. The argument from entropy is one of the most powerful arguments against the spontaneous formation of life from a random association of non-living chemicals...

    NASA scientists studying the origin of life have reproduced uracil, a key component of our hereditary material, in the laboratory. They discovered that an ice sample containing pyrimidine exposed to ultraviolet radiation under space-like conditions produces this essential ingredient of life. Pyrimidine is a ring-shaped molecule made up of carbon and nitrogen and is the basic structure for uracil, part of a genetic code found in ribonucleic acid (RNA). RNA is central to protein synthesis, but has many other roles. "We have demonstrated for the first time that we can make uracil, a component of RNA, non-biologically in a laboratory...

    While Charles Darwin’s On the Origin of Species has been described as “a grand narrative—a story of origins that would change the world”,1 ironically his book very pointedly avoided the question of the origin of life itself. This ought not be surprising. Darwin’s theory of the origin of species “by means of natural selection”2 presupposes self-reproduction, so can’t explain the origin of self-reproduction. Unfortunately, many proponents of evolution seem unaware of that. They don’t acknowledge that natural selection requires pre-existing life. As leading 20th century evolutionist Theodosius Dobzhansky lamented: ...

    Former Nature editor Philip Ball once commented that ‘there is no assembly plant so delicate, versatile and adaptive as the cell” (1). Emeritus Professor Theodore Brown chose to wax metaphorical by likening the cell to a fully-fledged factory, with its own complex functional relationships and interactions akin to what we observe in our own manufacturing facilities (2). In recent years the seemingly intractable problem of explaining how the first cell came into existence through chance events, otherwise known as the ‘Chance Hypothesis’, has become more acute than ever as scientists have begun to realize that a minimum suite of functional...

    Castle Rock, Colorado—Despite the first major snowstorm of the season, and unrelenting efforts by malicious Darwinists to prevent people from registering, a huge crowd of around 1,000 people showed up Friday night to hear Dr. Stephen Meyer present the DNA evidence for intelligent design based on his new book Signature in the Cell. Meyer, Michael Behe, David Berlinski, and myself are in Colorado to speak at the Legacy of Darwin ID Conference sponsored by Shepherd Project Ministries. On Saturday, Michael Behe will present the evidence against modern Darwinism from his books Darwin’s Black Box and The Edge of Evolution;...
