For a time, unless one had a hoard of cash stored up in ones home, it was impossible to get cash at all. 85 percent of Puerto Rico is still without power... Bloomberg continues: "When some generator-powered ATMs finally opened, lines stretched hours long, with people camping out in beach chairs and holding umbrellas against the sun." In an earlier article from September 25, Bloomberg noted how, without cash, necessities were simply unavailable:
"Cash only," said Abraham Lebron, the store manager standing guard at Supermax, a supermarket in San Juan's Plaza de las Armas. He was in a well-policed area, but admitted feeling like a sitting duck with so many bills on hand. "The system is down, so we can't process the cards. It's tough, but one finds a way to make it work."
Scientists also now think that differences in hair color, mood and whether someone will smoke or have an eating disorder could all be related to inter-breeding, after comparing ancient DNA to 112,000 British people who took part in the UK Biobank study. The Biobank includes genetic data along with information on many traits related to physical appearance, diet, sun exposure, behavior, and disease and helps scientists pick apart which traits came from Neanderthals. Dr Janet Kelso, of the Max Planck Institute for Evolutionary Anthropology, in Germany, said: "We can now show that it is skin tone, and the ease with which one tans, as well as hair color that are affected."
A tiny wobble in the signal, picked up by Ligo's twin instruments and the Virgo detector on 14 August, could be traced back to the final moments of the merger of two black holes about 1.8 billion years ago. The black holes, with masses about 31 and 25 times the mass of the sun, combined to produce a newly spinning black hole with about 53 times the mass of the sun. The remaining three solar masses were converted into pure energy that spilled out as deformations that spread outwards across spacetime like ripples across a pond. Detecting these tiny distortions has required detectors sensitive enough to measuring a discrepancy of just one thousandth of the diameter of an atomic nucleus across a 4km laser beam. A paper about the latest discovery has been accepted for publication in the journal Physical Review Letters.
The researchers analyzed data collected between 2004 and 2016. During these 12 years, the scientists detected more than 30,000 ultra-high-energy cosmic rays. If ultra-high-energy cosmic rays came from the Milky Way, one might perhaps expect them to come from all across the sky, or perhaps mostly from the direction of the supermassive black hole at the galaxy's center. However, the researchers saw that ultra-high-energy cosmic rays mostly came from a broad area of sky about 90 degrees away from the direction of the Milky Way's core.
Researchers say 80 percent of North Americans live in areas where light pollution blots out the night sky. Central Idaho contains one of the few places in the contiguous United States large enough and dark enough to attain reserve status, Barentine said. Only 11 such reserves exist in the world... The proposed Idaho reserve is mainly land managed by the U.S. Forest Service and contains the wilderness of the Sawtooth National Recreation Area... Leaders in the cities of Ketchum and Sun Valley, the tiny mountain town of Stanley, other local and federal officials, and a conservation group have been working for several years to apply this fall to designate 1,400 square miles (3,600 square kilometers) as a reserve. A final decision by the association would come about 10 weeks after the application is submitted.
Some think a surge in industrial pollution after World War II may have produced more pollutant particles that blocked the Sun's energy and exerted a cooling effect on the oceans. "The pollution reduced a lot of hurricane activity," said Gabriel Vecchi, professor of geosciences at Princeton University's Environmental Institute. Pollution began to wane in the 1980s due to regulations such as the Clean Air Act, allowing more of the Sun's rays to penetrate the ocean and provide warming fuel for storms. Vecchi said the "big debate" among scientists is over which plays a larger role -- variations in ocean currents or pollution cuts. There is evidence for both, but there isn't enough data to answer a key question...
The burning of fossil fuels, which spew greenhouse gases into the atmosphere and warm the Earth, can also be linked to a rise in extreme storms in recent years. Warmer ocean temperatures yield more moisture, more rainfall, and greater intensity storms. "It is not a coincidence that we're seeing more devastating hurricanes," climatologist Michael Mann of Penn State University told AFP in an email. "Over the past few years, as global sea surface temperatures have been the warmest on record, we've seen the strongest hurricanes -- as measured by peak sustained winds -- globally, in both Southern and Northern Hemisphere, in both Pacific and now, with Irma, the open Atlantic," he added. "The impacts of climate change are no longer subtle. We're seeing them play out in real time, and the past two weeks have been a sadly vivid example."
The so-called G3 level storm is the result of what's called a coronal mass ejection, where magnetic interactions on the sun launch part of its outer atmosphere of superheated plasma into space. When that burst of radiation gets near earth -- barreling toward us at a million miles per hour, it takes about two days to make the journey -- its magnetic field interacts with Earth's, Rutledge says. Northern U.S. and Canadian residents hoping to catch a glimpse of the aurora will get their best shot on Wednesday night and early Thursday, and the Space Weather Prediction Center posts 30-minute forecasts of the colorful sky phenomenon's intensity.
The images above are likely created because people were shooting in Live View mode, allowing them to compose the image using the back of their screen, instead of risking damage to their eyes by looking through the viewfinder. However, those who didn't use live view (and hopefully guess and checked instead of staring through the viewfinder), were more likely to face damage to their camera's mirror. While this damage was far rarer, we did get one particular camera with a damaged mirror box caused by the sun.
XFEL is the world's third major X-ray laser facility -- projects in Japan and the U.S. have already spawned major advances in structural biology and materials science. The European beam is more powerful, but most significantly has a far higher pulse rate than either of its predecessors. "They can send 100 pulses out per second, we can send 27,000," said Robert Feidenhan'l, chairman of the European XFEL management board. This matters because to study chemical reactions or biological processes, the X-ray strobe is used to capture flickering snapshots of the same system at different time-points that can be stitched together into a film sequence.
In my town it was cloudy all morning -- though I got a postcard from friends experiencing "the path of totality" in Idaho City. But how about you? How did you experience this week's solar eclipse?
Manish Panjwani's Los Angeles-based astronomy product business, AgenaAstro, has sold three times its average monthly revenue in the past month. Ninety-five percent is related to the solar eclipse... Panjwani's eclipse glasses come from two NASA-approved sellers: Thousand Oaks Optical in Arizona and Baader Planetarium in Germany. He said he provided documentation to Amazon proving the products' authenticity weeks ago, with no response from Amazon. On Saturday morning, he woke up to 100 emails from customers after Amazon issued a recall for his products. "People have some of the best glasses in the world in their hands right now and they don't believe in that product," he said. "They're out there looking for something inferior." Panjwani said Amazon is temporarily retaining some of his profits because of the recall. He also has almost 5,000 glasses at an Amazon warehouse, which customers can no longer purchase. "That's just sitting there. I cannot sell it and I cannot get it back in time for the eclipse," he said.
