Researchers Discover Way To Spot Crappy Coffee 184

Posted by samzenpus from the one-of-these-things-is-not-like-the-other dept.
sciencehabit writes "People who enjoy the most expensive coffee in the world can soon sip without worry: Researchers have come up with a way to tell if their cuppa joe is real or faux. The luxury drink in question—Kopi Luwak—is produced from coffee beans pooped out by the palm civet, a time-consuming process that helps contribute to the beverage's price tag of between $330 to $500 per kilogram. In a new study, researchers chemically analyzed four different blends of coffee—authentic Kopi Luwak, regular coffee, a 50/50 mix of the two, and a brew of coffee beans that producers had chemically treated in an attempt to simulate mammalian digestion. Of the hundreds of organic substances naturally present in coffee, a handful enabled the team to distinguish Kopi Luwak from the other brews. The technique may even be sensitive enough to distinguish pure Kopi Luwak from versions adulterated with varying percentages of other coffees—which offers some degree of reassurance when your morning mud costs about $15 a cup."

For Overstated Claims, Gore, Tesla Upbraided By NWS, NHTSA Respectively 195

Posted by timothy from the my-hubris-meter-goes-to-12 dept.
barlevg writes "In a recent interview, former Vice President and environmental activist Al Gore made a bold claim, that man-made global warming was causing hurricanes to be formed of such severity that 'they're adding a 6' to the hurricane scale, going on to say that 'The fingerprint of man-made global warming is all over these storms and extreme weather events.' In response, the National Weather Service has responded that they have no plans to add a 'doomsday Category 6' to their rating scale: 'No, we're not pursuing any such change. I'm also not sure who VP Gore means by "they,"' also noting that 'Category 5 has no ceiling: it includes hurricanes with top sustained winds of 157 mph and higher.' Furthermore, a recently leaked United Nations climate assessment claims only 'low confidence' of a link between human activity and increased hurricane severity and that this is likely due to increased human settlement in coastal areas and other regions vulnerable to natural disasters." Along similar lines, the National Highway Traffic Safety Administration says that Tesla's Model S, no matter how safe it is, doesn't get any special grade inflation: there's no "5.4" score (as the company did in a press release this week), because that's just not how the NHTSA keeps score.

Magellan II's Adaptive Optics Top Hubble's Resolution 136

muon-catalyzed writes "The incredible 'first light' images captured by the new adaptive optics system called Magellan|AO for "Magellan Adaptive Optics" in the Magellan II 6.5-meter telescope are at least twice as sharp in the visible light spectrum as those from the NASA's Hubble Space Telescope. 'We can, for the first time, make long-exposure images that resolve objects just 0.02 arcseconds across — the equivalent of a dime viewed from more than a hundred miles away,' said Laird Close (University of Arizona), the project's principal scientist. The 6.5-meter Magellan telescopes in the high desert of Chile were widely considered to be the best natural imaging telescopes in the world and this new technology upgraded them to the whole new level. With its 21-foot diameter mirror, the Magellan telescope is much larger than Hubble with its 8-foot mirror. Until now, Hubble always produced the best visible light images, since even large ground-based telescope with complex adaptive optics imaging cameras could only make blurry images in visible light. The core of the new optics system, the so-called Adaptive Secondary Mirror (ASM) that can change its shape at 585 points on its surface 1,000 times each second, counteracts the blurring effects of the atmosphere."

Dentist Wants To Clone John Lennon Using DNA Extracted From Lennon's Tooth 224

Posted by samzenpus from the with-a-little-help-from-my-molar dept.
dryriver writes "People fantasizing about a Beatles comeback tour might yet see their dream come true, all thanks to Dr. Michael Zuk. This dentist is the proud owner of one of John Lennon's teeth, and hopes to use it to clone the musician. By the looks of it, Dr. Michael Zuk came in possession of the tooth in 2011. At that time, he purchased the molar at an auction organized in the United Kingdom, and paid about $30,000 (€22,424) for it. According to The Inquisitr, the dentist is now working alongside scientists in the United States, who are helping him figure out a way to extract DNA from the tooth without damaging it in the process. This DNA would serve to bring back John Lennon. Apparently, Dr. Michael Zuk hopes that his project will snowball into a scientific and pop-cultural revolution. 'To potentially say I had a small part in bringing back one of Rock's greatest stars would be mind-blowing. I am nervous and excited at the possibility that we will be able to fully sequence John Lennon's DNA, very soon I hope,' the dentist reportedly commented on the importance of his work."

Ancient Egyptians Made Iron Jewelry From Pieces of Meteorite, Archaeologists Say 47

Posted by samzenpus from the star-metal dept.
fangmcgee writes "Researchers at the Petrie Museum of Egyptian Archaeology at University College London have found that a collection of ancient jewelry is out of this world. The 5,000-year-old Egyptian beads, previously thought to be made from iron from Earth have been found to be made from hammered pieces of meteorite. Strung together with gold, gemstones, and other minerals, the beads pre-date iron smelting, showcasing the metalworking mastery of fourth millennium B.C. Egyptians."
