Blood Moon Tunes: Music to Make Your 'Supermoon' Lunar Eclipse Rock As you settle in Sunday night (Sept. 27) to watch the supermoon lunar eclipse, kick back with some moon tunes as chosen by Space.com's staff. The moon has always fascinated humans, ever present and ever changing in the sky, and that fascination has inspired countless moon-based melodies. A full moon can mean romance or chaos and disaster; a thin silver sliver spells mystery, changeability or tranquility. What might a supermoon lunar eclipse represent? Listen below to some moon favorites: NASA has contemplated the moon in song as well: Steven Williams from NASA's Planetary Science Division pulled together an infographic and long list of moon-inspired refrains. The infographic pulls out classic moon tunes, songs about the Apollo moon missions, and even songs for a rainbow of multicolored moons (from "Red Moon" by The Walkmen down to "Kiko and the Lavender Moon" by Los Lobos). To prepare for Sunday's eclipse, check out Space.com's viewing guide or catch up on the science behind it.

un cas de chimérisme © Kristin Klein. En temps normal, l'histoire, racontée sur le site Buzzfeed, pourrait n'être que la mise au jour d'un banal cocufiage. Elle commence ainsi : Monsieur et Madame X (ils ont voulu rester anonymes) sont américains et ont un fils, né en juin 2014. Or l'on s'aperçoit que ce dernier est du groupe sanguin AB alors que ses parents sont tous les deux du groupe A. La première réaction logique, qui est celle de ce couple, consiste à se dire que la clinique où la FIV a été pratiquée a interverti les éprouvettes de sperme et malencontreusement fait rencontrer à l'ovule de Madame X un spermatozoïde qu'il n'aurait jamais dû croiser sur sa route. Les résultats sont à tomber par terre. Voici ce qui s'est très probablement passé : dans le ventre de sa mère, Monsieur X avait un faux jumeau – porteur, dans son groupe sanguin, du fameux B dont tout est parti. Le cas de Monsieur X est exceptionnel mais pas unique.

NASA Earth Observatory : Home 3 days fasting Des chercheurs d'une équipe de l'Université de Californie du sud (USC) affirment avoir trouvé le moyen de contraindre le corps humain à se régénérer. Une découverte annoncée comme «capitale». Jeûner pendant 72 heures peut permettre de reconstruire l’ensemble du système immunitaire même chez les personnes âgées ou gravement malades telle est la conclusion de cette nouvelle étude scientifique. Si jeûner est considéré comme néfaste pour l’organisme par les nutritionnistes, priver le corps de nourriture pendant trois jours contraindrait ensuite la moelle osseuse à produire de grandes quantités de globules blancs qui combattent les infections. Cette découverte peut être particulièrement utile aux malades dont le système immunitaire a été affaibli, par exemple les cancéreux traités par des chimiothérapies. Selon les chercheurs d’USC, jeûner lance un processus de régénération.

Some of the Apollo Missions High Resolution Film Scans quantum supremacy For Google it was a historic announcement: a declaration that it had won the race to achieve “quantum supremacy” – the moment that a futuristic quantum computer performed a task that stumped even the most powerful standard computer in the world. But for all the fanfare, which saw Google’s CEO Sundar Pichai compare the feat to building the first rocket to reach space, the claim has sparked a bunfight. The tech firm’s rival, IBM, was swift to dismiss the excitement. Google has not, it asserts, achieved the highly prized goal of quantum supremacy. Google published its claim in the journal Nature on Wednesday after an earlier report on the work appeared briefly on a Nasa website last month. To demonstrate the device’s computational prowess, the scientists set it the deeply contrived task of checking the randomness of a sequence of numbers. “To our knowledge, this experiment marks the first computation that can be performed only on a quantum processor,” the authors write.

Our SpaceFlight Heritage: One giant leap, the flight of Apollo 11 Forty-six years ago today, the crew of Apollo 11 lifted off for the Moon - and the history books. Photo Credit: NASA Gregory Cecil July 16th, 2015 Forty-six years ago today, on July 16, 1969, the crew of Apollo 11 lifted off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida – for the Moon. At 9:32 a.m. After two prior flights that went on to orbit the Moon by the crews of Apollo 8 and Apollo 10, the trio of Apollo 11 was ready to fulfill the late President Kennedy’s goal of, “… I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth.” The three spaceflight veterans included the mission’s commander, Neil Armstrong, the command module pilot Michael Collins, and lunar module pilot Edwin “Buzz” Aldrin. Each of them was experienced, having flown before on previous missions during the Gemini Program. Former U.S. Video courtesy of NASA Related Reading July 16, 2014 Gregory N.

crispr use inside body Scientists say they have used the gene editing tool Crispr-Cas9 inside a person’s body for the first time, a new development in efforts to operate on DNA to treat diseases. A patient recently underwent a procedure at the Casey Eye Institute at Oregon Health & Science University in Portland for an inherited form of blindness, the companies that make the treatment announced on Wednesday. They would not give details on the patient or when the surgery occurred. It may take up to a month to see whether the procedure worked to restore vision. If the first few attempts seem safe, doctors plan to test the technique on 18 children and adults. “We literally have the potential to take people who are essentially blind and make them see,” said Charles Albright, the chief scientific officer at Editas Medicine, a Massachusetts-based company developing the treatment with Dublin-based Allergan. Doctors think they need to fix between one-tenth and one-third of the cells to restore vision.

Apollo was a three-part spacecraft: the command module (CM), the crew’s quarters and flight control section; the service module (SM) for the propulsion and spacecraft support systems (when together, the two modules are called the CSM); and the lunar module (LM), to take two of the crew to the lunar surface, support them on the Moon, and return them to the CSM in lunar orbit. The CM, 12 feet (3.63 meters) long and shaped like a blunt cone, was at the front or top of the main spacecraft. When all was said and done?

mutant enzyme recycles plastic A mutant bacterial enzyme that breaks down plastic bottles for recycling in hours has been created by scientists. The enzyme, originally discovered in a compost heap of leaves, reduced the bottles to chemical building blocks that were then used to make high-quality new bottles. Existing recycling technologies usually produce plastic only good enough for clothing and carpets. The company behind the breakthrough, Carbios, said it was aiming for industrial-scale recycling within five years. It has partnered with major companies including Pepsi and L’Oréal to accelerate development. Independent experts called the new enzyme a major advance. Billions of tonnes of plastic waste have polluted the planet, from the Arctic to the deepest ocean trench, and pose a particular risk to sea life. The new enzyme was revealed in research published on Wednesday in the journal Nature. The team used the optimised enzyme to break down a tonne of waste plastic bottles, which were 90% degraded within 10 hours.

Our SpaceFlight Heritage: Remembering Apollo 10 Photo Credit: John Young / NASA David Darling May 18th, 2014 On May 18th, 1969, at 12:49 p.m. EDT, Apollo 10 blasted off from Cape Kennedy on the fourth manned flight of the Apollo Project and the final rehearsal for the first manned lunar landing. The plume from Apollo 10’s Saturn V rumbles outward. Apollo 10’s main purpose was to test rendezvous and docking operations between the Command and Service Module (CSM) and the Lunar Module (LM) in lunar orbit. Up to this point, the mission had gone entirely to plan without any undue alarms. Splashdown took place in the Pacific Ocean at 12:52 p.m. Photo Credit: NASA A whole slew of records was set by the Apollo 10 mission. “I had flown two flights before, you know space is so beautiful when you look down at the Earth with all that you see – but all we had was the Hasselblad film and little 16 millimeter cameras, it was just short clips. Snoopy’s fate however would be different from that of its kin. Welcome to The Spaceflight Group! May 18, 2015

bombe H En 2013, l’Assemblée générale des Nations Unies a proclamé le 26 septembre, Journée internationale pour l’élimination totale des armes nucléaires. Objectif : sensibiliser l’opinion publique aux bénéfices du désarmement. La bombe à hydrogène, ou bombe H, est la plus puissante des armes jamais imaginées par l'Homme. Cela vous intéressera aussi La bombe H, encore appelée bombe à hydrogènehydrogène ou bombe thermonucléaire, utilise le principe de la fusion nucléaire pour produire une explosion d'une puissance énorme. Fusion nucléaire et bombe H Si la bombe à hydrogène est à ce point plus puissante que la bombe A, c'est qu'elle repose sur des réactions de fusion nucléairefusion nucléaire. Pas de bombe H sans bombe A Cependant, pour parvenir à initier la fusion nucléaire, il est indispensable de créer des conditions de température et de pressionpression extrêmes.

Gecko inspired anchors Scientists at NASA's Jet Propulsion Laboratory (JPL) are honing the applications of a gecko-like gripping mechanism in the hope of making life a little less chaotic for those working aboard the International Space Station (ISS). The ever-inventive JPL workers have come up with a series of "astronaut anchors" for use both inside and outside the station, and have even equipped a robot with the tech, opening up the possibility of allowing it to safely operate on the exterior of the space station. Living in space is considerably more difficult than it is back on Earth. The team at JPL were inspired in the design of the new anchors by the gecko. The van der Waals force is an unusual quirk of physics that occurs when electrons orbiting the nuclei of an atom are unevenly distributed, creating an electric field with a positive and negative pole.
