'Junk' DNA Keeps Your Heart Beating by Jeffrey Tomkins, Ph.D. * A new research study has shown that large regions of the human genome, once thought to be useless junk, work to keep your heart functioning properly.1 When these areas of the genome malfunction, cardiovascular failure is often outcome, showing the importance of every piece of God's handiwork. The human genome is composed of more than just DNA sequences that produce proteins. In fact, only about 2% to 3% of the genome directly encodes information specifying the sequence of proteins. Despite this small percentage, about 80 to 90% of the...

Explanation: M61 is a barred spiral galaxy located in the nearby Virgo Cluster of Galaxies. Visible in M61 are a host of features common to spiral galaxies: bright spiral arms, a central bar, dust lanes, and bright knots of stars. M61, also known as NGC 4303, in similar to our own Milky Way Galaxy. M61 was discovered by telescope in 1779 twice on the same day, but one observer initially mistook the galaxy for a comet. Light from M61 takes about 55 million years to reach us. The above image of the central regions of M61 was taken with the...

Innovation in 3D printing is an ongoing process. There are always new ideas popping up, and new revelations taking place. However, one aspect of FDM 3D printers that hasnÂ’t really changed all that much in the past couple of years, is that of the extruder mechanics. A German engineer, by the name of Cem Schnitzler, hopes to change this though. His innovative design of a 3D printerÂ’s extruder could eventually allow for more variety in 3D printed objects. The idea is based off the concept of a microscope, and the way in which the microscopeÂ’s objective lenses may be rotated...

CHEYENNE, Wyo. — Sitting in the headquarters of the Wyoming Liberty Group, Susan Gore, founder of the conservative think tank, said new national science standards for schools were a form of “coercion,” adding, “I don’t think government should have anything to do with education.” Ms. Gore, a daughter of the founder of the company that makes Gore-Tex waterproof fabric, was speaking here weeks after the Republican-controlled Legislature made Wyoming, where coal and oil are king, the first state to reject the standards, which include lessons on human impact on global warming. The pushback came despite a unanimous vote by a...

Explanation: Sometimes land and sky are both busy and beautiful. The landscape pictured in the foreground encompasses Bryce Canyon in Utah, USA, famous for its many interesting rock structures eroded over millions of years. The skyscape above, photogenic in its own right, encompasses the arching central disk of our Milky Way Galaxy, streaks that include three passing airplanes and at least four Eta Aquariid meteors, and bright stars that include the Summer Triangle. The above image is a digital panorama created from 12 smaller images earlier this month on the night May 6. If you missed the recent Eta Aquariids...

What if everything you know is fake? That is a premise that was repeatedly explored by author Philip K. Dick in his science fiction novels. Some of his stories have been made into popular films such as “Total Recall,” where a blue collar worker in the far future doesn’t know whether he is really a secret agent or just pretending to be one as part of an implanted memory. In Dick’s novel “Time Out of Joint,” protagonist Ragle Gumm gets confirmation that something is terribly wrong with the world around him when he attempts to buy a beer at an...

Explanation: What will become of Jupiter's Great Red Spot? Recorded as shrinking since the 1930s, the rate of the Great Red Spot's size appears to have accelerated just in the past few years. A hurricane larger than Earth, the Great Red Spot has been raging at least as long as telescopes could see it. Like most astronomical phenomena, the Great Red Spot was neither predicted nor immediately understood after its discovery. Although small eddies that feed into the storm system seem to play a role, a more full understanding of the gigantic storm cloud remains a topic of continued research,...

Explanation: Gas giant Jupiter is the solar system's largest world with about 320 times the mass of planet Earth. It's also known for a giant swirling storm system, the Great Red Spot, featured in this sharp Hubble image from April 21. Nestled between Jupiter-girdling cloud bands, the Great Red Spot itself could still easily swallow Earth, but lately it has been shrinking. The most recent Hubble observations measure the spot to be about 10,250 miles (16,500 kilometers) across. That's the smallest ever measured by Hubble and particularly dramatic when compared to 14,500 miles measured by the Voyager 1 and 2...

Harrison Ford may be reprising yet another beloved film character he made famous decades ago. In late April it was confirmed the 71-year-old actor would pick up a Lightsaber once more to play Han Solo in the JJ Abrams-directed reworking of Star Wars. Then on Thursday Deadline reported Ford was being asked to step back into his role as Rick Deckard in the sequel to his 1982 science fiction thriller Blade Runner.

Explanation: Staring up into the martian sky, the Opportunity rover captured an image at 11:02 AM local mean time nearly every 3rd sol, or martian day, for 1 martian year. Of course, the result is this martian analemma, a curve tracing the Sun's motion through the sky in the course of a year (668 sols) on the Red Planet. Spanning Earth dates from July, 16, 2006 to June 2, 2008 the images are shown composited in this zenith-centered, fisheye projection. North is at the top surrounded by a panoramic sky and landscape made in late 2007 from inside Victoria crater....

Explanation: Cruising through the outer solar system, the Voyager 2 spacecraft made its closest approach to Neptune on August 25, 1989, the only spacecraft to visit the most distant gas giant. Based on the images recorded during its close encounter and in the following days, this inspired composited scene covers the dim outer planet, largest moon Triton, and faint system of rings. From just beyond Neptune's orbit, the interplanetary perspective looks back toward the Sun, capturing the planet and Triton as thin sunlit crescents. Cirrus clouds and a dark band circle Neptune's south polar region, with a cloudy vortex above...

On Monday, Washington Post columnist Michael Gerson took a tilt at climate skeptics. “The assumption that the vast majority in a scientific field is engaged in fraud or corruption is frankly conspiratorial,” Gerson wrote. As a non-scientist, he decided that the answer to the question of whether humans had warmed the planet was to trust scientists. The article’s timing was unfortunate. Three weeks ago, Lennart Bengtsson, a leading Swedish meteorologist approaching his 80s, announced that he was joining the avowedly skeptical Global Warming Policy Foundation think tank. In an interview with Speigel Online, Bengtsson spoke of the need for climate-model...

Explanation: If you were floating above the Earth right now, this is what you might see. Two weeks ago, the robotic SpaceX Dragon capsule that delivered supplies to the Earth-orbiting International Space Station (ISS) also delivered High Definition Earth Viewing (HDEV) cameras that take and transmit live views of Earth. Pictured above, when working, is the live video feed that switches between four cameras, each pointed differently. Watch white clouds, tan land, and blue oceans drift by. The above video will appear black when it is nighttime on the Earth below, but the space station's rapid 90-minute orbit compresses this...

Americans have something of a science problem. They swallow, for example, about $28 billion worth of vitamins each year, even though the Annals of Internal Medicine recently concluded that “[m]ost supplements do not prevent chronic disease or death, their use is not justified, and they should be avoided.” Americans often fear swallowing genetically modified plants (and Vermont recently required labeling of food containing genetically modified organisms, known as GMOs), though GMOs have “been consumed by hundreds of millions of people across the world for more than 15 years, with no reported ill effects,” according to the Journal of the Royal Society...

Explanation: Can a gas cloud grab a galaxy? It's not even close. The "claw" of this odd looking "creature" in the above photo is a gas cloud known as a cometary globule. This globule, however, has ruptured. Cometary globules are typically characterized by dusty heads and elongated tails. These features cause cometary globules to have visual similarities to comets, but in reality they are very much different. Globules are frequently the birthplaces of stars, and many show very young stars in their heads. The reason for the rupture in the head of this object is not completely known. The galaxy...

Explanation: How did we get here? Click play, sit back, and watch. A new computer simulation of the evolution of the universe -- the largest and most sophisticated yet produced -- provides new insight into how galaxies formed and new perspectives into humanity's place in the universe. The Illustris project -- the largest of its type yet -- exhausted 20 million CPU hours following 12 billion resolution elements spanning a cube 35 million light years on a side as it evolved over 13 billion years. The simulation is the first to track matter into the formation of a wide variety...

Explanation: The largest canyon in the Solar System cuts a wide swath across the face of Mars. Named Valles Marineris, the grand valley extends over 3,000 kilometers long, spans as much as 600 kilometers across, and delves as much as 8 kilometers deep. By comparison, the Earth's Grand Canyon in Arizona, USA is 800 kilometers long, 30 kilometers across, and 1.8 kilometers deep. The origin of the Valles Marineris remains unknown, although a leading hypothesis holds that it started as a crack billions of years ago as the planet cooled. Several geologic processes have been identified in the canyon. The...

Scientists in the Philippines have discovered a plant that can absorb large amounts of metal without itself being poisoned, a species called the Rinorea niccolifera, that can be used to clean up polluted soils and harvest commercially viable metals. The plant is one of only 450 species, known as hyperaccumulator plants, of 300,000 known vascular plants that can absorb significant amounts of metal though their roots. The lead researcher and author of a new study on the plant, Professor Edwino Fernando, from the University of the Philippines, said the leaves of the Rinorea niccolifera can absorb up to 18,000 parts...

It is, if you except the powers of human memory, the closest thing we have to a time machine. Scientists have created the first realistic model of the universe, capable of recreating 13 billion years of cosmic evolution. The simulation is called “Illustris,” and it renders the universe as a cube (350 million light-years on each side) with, its creators say, unprecedented resolution: The virtual universe uses 12 billion 3-D “pixels,” or resolution elements, to create its rendering. And that rendering includes both normal matter and dark matter. The rendering, importantly, also includes elliptical and spiral galaxies—bodies that, because of...
