Japanese Team Claims Discovery Of Elusive Element 113, And May Get To Name It | Popular... - 0 views

  • Japanese researchers claim they’ve seen conclusive evidence of the long-sought element 113, a super-heavy, super-unstable element near the bottom of the periodic table
  • not yet verified by the International Union of Pure and Applied Chemistry
  • if the IUPAC grants its blessing, the researchers could be the first team from Asia to name one of nature’s fundamental atoms.
  • ...5 more annotations...
  • Super-heavy elements do not occur in nature and have to be discovered in the lab, using particle accelerators, nuclear reactors, ion separators and other complex equipment
  • Science have been hunting for 113 for nine years, and have claimed to see it a few times already — but the evidence has never been this clear,
  • the team used a customized gas-filled recoil ion separator paired with a semiconductor detector that can pick out atomic reaction products
  • created element 113 by speeding zinc ions through a linear accelerator until they reached 10 percent of the speed of light.
  • ions then smashed into a piece of bismuth. When the zinc and bismuth atoms fused, they produced an atom with 113 protons

Heart repair breakthroughs replace surgeon's knife - 0 views

  • Many problems that once required sawing through the breastbone and opening up the chest for open heart surgery now can be treated
  • through a tube
  • These minimal procedures used to be done just to unclog arteries and correct less common heart rhythm problems
  • ...42 more annotations...
  • Now some patients are getting such repairs for valves, irregular heartbeats, holes in the heart and other defects—without major surgery
  • Doctors even are testing ways to treat high blood pressure with some of these new approaches
  • Instead of opening the chest, we're able to put catheters in through the leg, sometimes through the arm
  • Many patients after having this kind of procedure in a day or two can go home
  • It may lead to cheaper treatment, although the initial cost of the novel devices often offsets the savings from shorter hospital stays
  • Not everyone can have catheter treatment, and some promising devices have hit snags in testing
  • Others on the market now are so new that it will take several years to see if their results last as long as the benefits from surgery do.
  • these procedures have allowed many people too old or frail for an operation to get help for problems that otherwise would likely kill them
  • You can do these on 90-year-old patients
  • also offer an option for people who cannot tolerate long-term use of blood thinners or other drugs to manage their conditions
  • Heart valves
  • Millions of people have leaky heart valves. Each year, more than 100,000 people in the United States alone have surgery for them
  • Without a valve replacement operation, half of these patients die within two years, yet many are too weak to have one.
  • just over a year ago,
  • Edwards Lifesciences Corp. won approval to sell an artificial aortic valve flexible and small enough to fit into a catheter and be wedged inside the bad one
  • At first it was just for inoperable patients. Last fall, use was expanded to include people able to have surgery but at high risk of complications.
  • Catheter-based treatments for other valves also are in testing. One for the mitral valve
  • mixed review by federal Food and Drug Administration advisers this week; whether it will win FDA approval is unclear. It is already sold in Europe
  • Heart rhythm problems
  • Catheters can contain tools to vaporize or "ablate" bits of heart tissue that cause abnormal signals that control the heartbeat
  • Now catheter ablation is being used for the most common rhythm problem—atrial fibrillation, which plagues about 3 million Americans and 15 million people worldwide.
  • Ablation addresses the underlying rhythm problem. To address the stroke risk from pooled blood, several novel devices aim to plug or seal off the pouch
  • The upper chambers of the heart quiver or beat too fast or too slow. That lets blood pool in a small pouch off one of these chambers
  • Clots can form in the pouch and travel to the brain, causing a stroke
  • a tiny lasso to cinch the pouch shut. It uses two catheters that act like chopsticks. One goes through a blood vessel and into the pouch to help guide placement of the device, which is contained in a second catheter poked under the ribs to the outside of the heart. A loop is released to circle the top of the pouch where it meets the heart, sealing off the pouch.
  • A different kind of device
  • sold in Europe and parts of Asia, but is pending before the FDA in the U.S
  • like a tiny umbrella pushed through a vein and then opened inside the heart to plug the troublesome pouch.
  • Early results from a pivotal study released by the company suggested it would miss a key goal, making its future in the U.S. uncertain.
  • Heart defects
  • St. Jude Medical Inc.'s Amplatzer is a fabric-mesh patch threaded through catheters to plug the hole
  • In two new studies, the device did not meet the main goal of lowering the risk of repeat strokes in people who had already suffered one, but some doctors were encouraged by other results
  • Сlogged arteries
  • The original catheter-based treatment—balloon angioplasty—is still used hundreds of thousands of times each year in the U.S. alone
  • A Japanese company, Terumo Corp., is one of the leaders of a new way to do it that is easier on patients—through a catheter in the arm rather than the groin
  • Newer stents that prop arteries open and then dissolve over time, aimed at reducing the risk of blood clots, also are in late-stage testing
  • High blood pressure
  • About
  • 1 billion people worldwide have high blood pressure, a major risk factor for heart attacks
  • Researchers are testing a possible long-term fix for dangerously high pressure that can't be controlled with multiple medications.
  • uses a catheter and radio waves to zap nerves, located near the kidneys, which fuel high blood pressure
  • At least one device is approved in Europe and several companies are testing devices in the United States

Moon's Mysterious 'Ocean of Storms' Explained | Moon Impact Hypothesis | Space.com - 0 views

  • The largest dark spot on the moon, known as the Ocean of Storms, may be a scar from a giant cosmic impact that created a magma sea more than a thousand miles wide and several hundred miles deep
  • could help explain why the moon's near and far sides are so very different from one another,

  • hers have posed a number of explanations for the vast disparity between the moon's near and far sides. Some have suggested that a tiny second moon may once have orbited Earth before catastrophically slamming into the other moon, spreading its remains mostly on the moon's far side
  • Others have proposed that Earth's pull on the moon caused distortions that were later frozen in place on the moon's near side.
  • Mars' northern and southern halves are also stark contrasts from one another, and researchers had suggested that a monstrous impact may have been the cause
  • scientists in Japan say that a giant collision may also explain the moon's two-faced nature, one that gave rise to the Ocean of Storms
  • researchers analyzed the composition of the moon's surface using data from the Japanese lunar orbiter Kaguya/Selene

  • type of pyroxene is linked with the melting and excavation of material from the lunar mantle, and suggests the Ocean of Storms is a leftover from a cataclysmic impact.
  • This collision would have generated "a 3,000-kilometer (1,800-mile) wide magma sea several hundred kilometers in depth
  • that collisions large enough to create Oceanus Procellarum and the moon's other giant impact basins would have completely stripped the original crust on the near side of the moon
  • crust that later formed there from the molten rock left after these impacts would differ dramatically from that on the far side
  • Some researchers had speculated that the Procellarum basin was the relic of a gigantic impact
  • this idea was hotly debated because there were no definite topographic signs it was an impact basin
  • neighboring Earth likely experienced similar-sized impacts around the same period

  • Japanese astronaut Satoshi Furukawa poses with the LEGO model of the International Space Station that he built on board the real space station.
  • Although building the LEGO space station was an activity aimed at students, it was not all child's play.
  • LEGOs are an example of something that is a lot of fun on the ground but it can be very frustrating when you have a lot of loose floating pieces
  • To keep the bricks contained and to protect against some potentially serious dangers

  • Fire is usually not one of the warnings that people find on the side of LEGO boxes.
  • there are flammability concerns about the LEGOs
  • challenging part was using the thick rubber gloves in the containment system because it made me clumsy in building the LEGO space station
  • real space station was declared "assembly complete" on May 29, 2011
  • the model was launched in partially-preassembled "chunks" to help make up for the difficulties working with very small pieces in microgravity
  • The space station could not be launched fully-assembled, because like the real orbiting outpost, it could only be built in space
  • It's a solid model but I believe it can't bear its own weight under gravity
  • LEGO station's time fully assembled was short lived however
  • Due to the flammability hazards, the toy bricks could only be exposed to the open cabin air for two hours.

January 26 - Today in Science History - Scientists born on January 26th, died, and events - 0 views

  • Canadian earthquake   In 1700, an earthquake, the most intense Canada has ever seen, hit the sea floor off the British Columbia coast. Long before Europeans first landed on Vancouver Island, native legend tells of a great disaster. The sea rose in a heaving wave, and landslides buried a sleeping village. Myth was resolved with science in 2003 by government research. Earthquakes of that intensity cause tidal waves, and Japanese written history tells of a massive tsunami striking fishing villages the next day along the coast of Honshu, killing hundreds. Coupled with geological evidence of the level 9 quake, the connection was clear. Mythology and seismology came together to validate history.

Scientists Identify Cause of Japan's Devastating 2011 Tsunami - 0 views

  • In March 2011, a devastating tsunami struck Japan's Tohoku region

  • could help researchers provide earlier warnings
  • During their study
  • scientists underwent a 50-day expedition on the Japanese drilling vessel Chikyu
  • They then drilled three holes in the Japan Trench area in order to study the rupture zone of the 2011 earthquake
  • a fault in the ocean floor where two of Earth's major tectonic plates meet deep beneath the surface of the Pacific Ocean.
  • The conventional view among geologists
  • has been that deep beneath the seafloor, where rocks are strong, movements of the plates can generate a lot of elastic rebound
  • Closer to the surface of the seafloor, where rocks are softer and less compressed, this rebound effect was thought to taper off
  • In fact
  • the largest displacement of plates before the 2011 tsunami occurred in 1960 off the coast of Chile
  • That's when a powerful earthquake displaced seafloor plates by an average of 20 meters
  • The Tohoku earthquake, in contrast, displaced its own plates by 30 to 50 meters.
  • So what caused this unexpectedly violent slip
  • the fault itself is very thin--less than five meters thick in the area sampled.
  • makes it the thinnest plate boundary on Earth.
  • In addition, clay deposits that fill the narrow fault are made of extremely fine sediment, which makes it extremely slippery
  • these findings don't just show researchers a bit more about the past; they also have implications for the future
  • Other subduction zones in the northwest Pacific where this type of clay is present--from Russia's Kamchatka peninsula to the Aleutian Islands--may also be capable of generating similar, huge earthquakes
