Credit: Bob King If you like planets, don't forget the combo of Jupiter and Spica at the opposite end of the sky. Jupiter climbs out of bed and over the southeastern horizon about 9 p.m. local time in late March, but to see it and Spica, Virgo's brightest star, give it an hour and look again at 10 p.m. or later. Quite the duo! You're not afraid of getting up with the first robins are you? If you set your alarm to a half hour or so before the first hint of dawn's light and find a location with an open view of the southeastern horizon, you might be first in your neighborhood to spot Terry Lovejoy's brand new comet. His sixth, the Australian amateur discovered C/2017 E4 Lovejoy on the morning of March 10th in the constellation Sagittarius at about 12th magnitude. C/2017 E4 Lovejoy glows blue-green this morning March 26. Structure around the nucleus including a small jet is visible.

His most successful years as a player were with the rough-edged St. Louis Cardinals, Dizzy Dean's Gashouse Gang, in the mid-1930s, where he fit in well with the grungy, foul-mouthed team. But Durocher's great chance came in 1939, when the Brooklyn Dodgers, after six straight losing seasons, offered to make him the team's manager. He quickly built the nucleus of a good team, purchasing the young Pee Wee Reese to replace himself at shortstop, grabbing such fading stars as Dixie Walker off the American League's waivers, finding the likes of Dolph Camilli and Kirby Higbe, and stealing the rookie sensation Pete Reiser from the Cardinals. In 1941, Durocher's third season as manager, the Dodgers had a hundred-win season and captured the National League pennant for the first time in in 21 years. Though he did better with the Giants, managing them to the pennant in 1951 and World Series victory in 1954, his first years as a manager with the Dodgers may have been his most creative and impressive.

The Rosetta spacecraft learned a great deal during the two years that it spent monitoring Comet 67P/Churyumov-Gerasimenko from August 6th, 2014 to September 30th, 2016. As the first spacecraft to orbit the nucleus of a comet, Rosetta was the first space probe to directly image the surface of a comet, and observed some fascinating things in the process. For instance, the probe was able to document some remarkable changes that took place during the mission with its OSIRIS camera. According to a study published today (March. 21st) in Science , these included growing fractures, collapsing cliffs, rolling boulders and moving material on the comet's surface that buried some features and exhumed others. These changes were noticed by comparing images from before and after the comet reached perihelion on August 13th, 2015 the closets point in its orbit around the Sun.

Beta particles can even penetrate the skin and burn the tissue beneath. The third type is gamma radioactivity. Now, this is the emission not of particles of matter at all, but tiny lumps of light - high energy photons that fly out from the nucleus

Enlarge / Intact genome from a mouse embryonic stem cell with 20 chromosomes colored differently (credit: University of Cambridge and MRC Laboratory of Molecular Biology ) In a first, researchers have worked out a way to unravel and model the tangled, 3D structures of intact mammalian genomes from individual cells. The new method, published Monday in Nature , could help researchers study how the complex loops, twists, and bunches of a tightly packaged genome influence which bits of the blueprints are actively used by the cells, and when. In humans, for instance, genome packaging bundles nearly two meters’ worth of DNA strings into a nucleus about 0.005 millimeters wide. How all that DNA is bundled affects whether important genes are available for decoding by cellular machinery, while others are boxed up and shoved aside until they’re needed. Such carefully orchestrated genetic activity affects everything a cell does—from carrying out basic functions, to allowing stem cells to differentiate into any type of cell, to triggering diseases.

Like so many things in the quantum world, it all started with an unexpected outcome... Giving Mass to the Massless In the early 1960's, quantum physicists began to come face-to-face with particles they called massless bosons . They presented quite a problem, as massless particles tended to be associated with long-range forces, such as photons are to electromagnetism. For short-range forces within the nucleus of an atom, particles tended to have mass. And these massless bosons kept popping up in theory... they were completely out of place. So the hunt was on to figure out how to give these massless particles mass. There were just as many physicists, however, trying to prove that the massless bosons did not exist at all. One of these men was Steven Weinberg. Steven Weinberg At this point in time, no one had actually seen a massless boson, mind you.

mp3 As reported in Science , Chen's team put a mouse in an enclosure with a computer screen. The researchers then played a video that showed another mouse scratching. Within a few seconds, the mouse in the enclosure would start scratching, too, Chen says. This was very surprising because mice are known for their poor vision. They use smell and touch to explore areas, so we didn't know whether a mouse would notice a video. Not only did it see the video, it could tell that the mouse in the video was scratching. Next, the researchers identified a structure called the suprachiasmatic nucleus (SCN), a brain region that controls when animals fall asleep or wake up. The SCN was highly active after the mouse watched the video of the scratching mouse. When the mouse saw other mice scratching—in the video and when placed near scratching littermates—the brain's SCN would release a chemical substance called GRP (gastrin-releasing peptide).

The common theme among the perpetrators is the Satanism practiced by the Western Elite, who are gradually being exposed for their pedophilia and child sacrifice rituals. Their symbols are all through the corporate signposts, from Proctor & Gamble to HSBC and much deeper. The Seven Bowls of death and pestilence are central to the Agenda-21 Global Genocide Plan. Its players include Bill Gates of Microsoft, George Soros, and companies Halliburton, Monsanto along with many others. They have a nucleus in the big banks and large energy firms. With destruction of economic foundations, the globalists hope to install the Global Fascist State, usurp all powers, reduce the individual to a true vassal serf, and turn the nations into a gigantic prison camp. No, the Jackass has not lost his mind. This threat to humanity is very real, in progress, and might be interrupted.

BIOLOGY’S biggest division is not between plants and animals, nor even between multicellular and single-celled creatures. It is between prokaryotes and eukaryotes. Prokaryotesbacteria are the most familiar sort—are simple. Their DNA is an unadorned circular molecule between 500,000 and 10m geneticletters” long. As such, it is fairly easy to replicate from off-the-shelf chemicals. The DNA of eukaryotesanimals, plants, fungi and so on—is both more abundant and more complex than that. It may have hundreds of millions, even billions, of letters and it is organised into several elongated chromosomes inside a cell’s nucleus. Synthesising a eukaryote’s genome is thus a far harder task than creating its prokaryote equivalent. But if biology is ever to be brought within the realm of technology in the ways that physics and chemistry have been, it is an essential task.

Switching quarterbacks from Drew Brees to Ryan Tannehill didn't cause a decrease in his performance. Per Ryan Smith of Pro Football Focus, Stills finished 2016 tied with Pittsburgh Steelers wide receiver Antonio Brown for most receiving touchdowns on passes that traveled at least 20 yards in the air (eight). Stills isn't a great all-around wide receiver. He's the definition of an all-or-nothing playmaker who has only had more than 42 catches in a season once with a catch percentage of 47.9 since joining the Dolphins. The Dolphins have found a terrific offensive nucleus to build around, with Stills proving to be a key piece of the puzzle last year. They also have Jarvis Landry as Tannehill's No. 1 option and DeVante Parker still developing after being a first-round pick in 2015. Running back Jay Ajayi also had a breakout season with 1,272 rushing yards and eight touchdowns.
