How To See The Closest Supernova In A Generation!
|9:48:54 PM, Monday, September 12, 2011|
"After your death you will be what you were before your birth." -Arthur Schopenhauer
If only every star's death could be as glorious as a supernova, rocketing anywhere from thousands to millions of Earth-masses out of a star and into interstellar space. When we get one in our galaxy, like we do every few hundred years, the view from Earth can be spectacular.
The Crab Nebula, above, sprung from a supernova nearly a thousand years ago, in 1054. And while that supernova, and a handful of others since, have been visible from Earth with nothing more than the naked eye, we haven't had that pleasure since 1604. The remnant of that supernova, of course, is still visible today, although it looks no more impressive in visible light than the very end of a fireworks display.
While every astronomer would love to have the chance to see a supernova in our own galaxy, these aren't the sorts of things we can control. Instead, we have to be content to see what the Universe gives us to look at. We came close a generation ago, in 1987, when a supernova went off in the Large Magellanic Cloud, a satellite galaxy just 160,000 light years away. Under ideally dark skies, the supernova was just barely visible to the unaided eye in the Southern Hemisphere.
For a generation since then, we haven't had a supernova occur anywhere near as close as that one. Which is too bad, because our telescope technology and coverage, today, is the greatest it's ever been.
But last month, on August 24th, the closest supernova since SN1987a went off in our neighbor galaxy -- the Pinwheel Galaxy -- just 21 million light years away..."
Astronomy Picture of the Day: Star Factory Messier 17
|9:42:11 PM, Monday, September 12, 2011|
-- "Sculpted by stellar winds and radiation, the star factory known as Messier 17 lies some 5,500 light-years away in the nebula-rich constellation Sagittarius. At that distance, this degree wide field of view spans almost 100 light-years, courtesy of the European Southern Observatory's new VLT Survey Telescope and OmegaCAM. The sharp, false color image includes both optical and infrared data, following faint details of the region's gas and dust clouds against a backdrop of central Milky Way stars. Stellar winds and energetic light from hot, massive stars formed from M17's stock of cosmic gas and dust have slowly carved away at the remaining interstellar material producing the cavernous appearance and undulating shapes. M17 is also known as the Omega Nebula or the Swan Nebula. "
Woman Dies After Injecting Face With Hot Beef Fat
|9:38:57 PM, Monday, September 12, 2011|
"An Illinois woman who injected hot beef fat into her face died Thursday of a bacterial infection soon after she administered the homemade cosmetic surgery. Oddly, doctors say the questionable injections had nothing to do with her death, which was deemed natural by Illinois’ Cook County Medical Examiner’s Office.
Janet Hardt, 63 of Homewood, Ill., boiled beef, extracted the fat and injected it into her face before she went to the hospital complaining that her face felt as if it was burning, according to ABC News’ Chicago affiliate WLS-TV.
The Chicago Sun-Times reported that Hardt had infections and scarring in her mouth and on her lips, but an autopsy declared her death was a result of peritonitis, an inflammation of the abdomen’s inner wall.
This bizarre story does not come without lessons, experts say.
“There are a lot people out there doing self-injections for wrinkles, but I don’t know of any medical associations that would recommend this,” said Dr. Phillip Haeck, president of the American Society of Plastic Surgeons. “It’s not worth taking a chance with your face to try to save money when it could ultimately cost you a lot more money.”
Hardt reportedly injected her face with the beef fat several times, and she also underwent several legitimate plastic surgery procedures. Because she injected herself multiple times with the animal product, Haeck said she was at risk of developing an allergic reaction.
“One of the injections could cause the skin to erode or ulcerate,” said Haeck. “We know that injections of animal proteins do not cause systemwide failure, but it tends to cause local reactions. A lot of people who have allergic reactions to animal proteins will say that their face is burning like this woman did. That’s probably what was going on here.”"

Newly Discovered Planet: Hot, Muggy And (Maybe) Liveable
|9:30:33 PM, Monday, September 12, 2011|
"European astronomers said Monday that they had found what might be the best candidate for a Goldilocks planet yet: a lump of something about 3.6 times as massive as the Earth, circling its star at the right distance for liquid water to exist on its surface — and thus, perhaps, to host life, as we narrowly imagine it.
The planet, known as HD 85512b, is about 36 light years from here, in the constellation Vela. It orbits its star at about a quarter of the distance that Earth circles the Sun, taking 58 days to make a year. That distance would put it in the star’s so-called habitable zone, if the planet is rocky and has some semblance of an atmosphere — “if everything goes right and you have clouds to shelter you,” as Lisa Kaltenegger of the Harvard-Smithsonian Center for Astrophysics and the Max Planck Institute for Astronomy in Heidelberg, Germany, summarized it.
Astronomers cautioned, however, that it would take years and observations from telescopes not yet built before those assumptions could be tested and a search for signs of life could be undertaken.
Neither humans nor their robot helpers are likely to be dispatched toward Vela anytime soon. But the finding did vault HD 85512b to the top of a list of the handful of Goldilocks candidates.
The Vela planet was part of a haul of more than 50 new exoplanets — as planets around other stars are called — discussed in a news conference on Monday hosted by the European Southern Observatory. They are the newest fruits of an eight-year observing program by astronomers based at the University of Geneva and led by Stephane Udry and Michel Mayor, working from a telescope at the European Southern Observatory in Chile. About 16 of them are so-called super-Earths, with masses less than 10 times the Earth, further encouraging astronomers that they are on the verge of finding planets like ours. A pair of papers — one with Dr. Mayor as lead author and the other with Francesco Pepe, also of Geneva, as lead author — have been submitted to Astronomy and Astrophysics, describing the planets.
The Geneva astronomers used a sensitive spectrograph known as Harps (an acronym for High Accuracy Radial velocity Planet Searcher) to detect wobble in the stars’ motions as planets swung around them. The wobble technique, however, only reveals the masses of exoplanets. Without further information like the size — which NASA’s Kepler satellite, also in the exoplanet business, measures by seeing the shadows of planets as they cross in front of their stars — or the composition, the astronomers cannot say for sure whether the Vela planet is made of rock, steam, iron, diamonds or something else. Nor can they tell what, if any, atmosphere it has. Kepler will be of no help because its gaze is fixed on a different swath of sky.
The star that the Vela planet circles is known as HD 85512, or Gliese 370, after Wilhelm Gliese, a German astronomer. The star is orange, about two-thirds as massive and about an eighth as luminous as our Sun..."
World Trade Center Tribute In Lights 2011

No Truce Expected In Global Patent Wars
|7:15:32 PM, Monday, September 12, 2011|
"Patent reform legislation passed by the US Congress may represent the most sweeping changes to the law in decades but the bill is not expected to end the courtroom wrangling between technology giants.
"My feeling is that it won't change the dynamics much of the ongoing patent wars," said Roger Kay of Endpoint Technologies Associates. "The problem is with patents in general, in that there's way too much patenting and people patent any old thing including how to toast bread."
Ed Black, president and chief executive of the Computer & Communications Industry Association (CCIA), said the bill, the America Invents Act, "doesn't effectively address the real serious problems of our patent system.
"The bill tinkers in various ways -- some things are good, some things are bad -- but it's not a gamechanger," Black said, agreeing with Kay that the main problem is "too many patents issued that are simply not high-quality patents."
Black noted that the US Patent and Trademark Office (USPTO) announced recently that it has issued its eight millionth patent.
"Most people think of patents as being like Edison and the light bulb," he said. "Tell me we've had eight million game-changing ideas."
The Senate passed the America Invents Act on Thursday by an 89-9 vote. It cleared the House of Representatives earlier this year by a similarly lopsided 304-117 margin.
Democratic Senator Patrick Leahy, a key author of the legislation, said the bill will "ensure that inventors large and small maintain the competitive edge that has put America at the pinnacle of global innovation."
The legislation notably shifts the granting of US patents from a "first to invent" system, which left considerable leeway for interpretation, to a "first to file" basis and seeks to reduce a backlog of 750,000 applications..."
Fish Living In Dark Caves Still Feel The Rhythm Of Life
|10:25:49 PM, Sunday, September 11, 2011|
"A blind, cave-dwelling fish in Somalia knows what time it is, but its "day" is twice as long as ours.
Most animals have an internal body clock, or circadian rhythm, that lasts around 24 hours and is modified by the light-dark cycle of a day.
But an international team, whose research is published in the open access journal PloS Biology, shows that certain blind cave fish have a circadian rhythm that lasts almost two days.
The cavefish, Phreatichthys andruzzii, has evolved for nearly two million years in the isolated darkness of caves beneath the Somali desert.
Professor Nick Foulkes, of the Karlsruhe Institute of Technology in Germany, said that this particular species was chosen "because it was such an extreme example, having been isolated from a day-night cycle for so long".
In the course of its evolution it has lost its eyes, colouration and scales, having no need for them in the pitch-black of an underground cave system.
But it appears that the absence of day and night has caused a much more profound change in the fish's life rhythm..."

Glowing Cats Help In Fight Against AIDS, Other Diseases
|7:13:49 PM, Sunday, September 11, 2011|
"Mayo Clinic researchers have developed a genome-based immunization strategy to fight feline AIDS and illuminate ways to combat human HIV/AIDS and other diseases. The goal is to create cats with intrinsic immunity to the feline AIDS virus. The findings -- called fascinating and landmark by one reviewer -- appear in the current online issue of Nature Methods.
Feline immunodeficiency virus (FIV) causes AIDS in cats as the human immunodeficiency virus (HIV) does in people: by depleting the body's infection-fighting T-cells. The feline and human versions of key proteins that potently defend mammals against virus invasion -- termed restriction factors -- are ineffective against FIV and HIV respectively. The Mayo team of physicians, virologists, veterinarians and gene therapy researchers, along with collaborators in Japan, sought to mimic the way evolution normally gives rise over vast time spans to protective protein versions. They devised a way to insert effective monkey versions of them into the cat genome.
"One of the best things about this biomedical research is that it is aimed at benefiting both human and feline health," says Eric Poeschla, M.D., Mayo molecular biologist and leader of the international study. "It can help cats as much as people."
Dr. Poeschla treats patients with HIV and researches how the virus replicates. HIV/AIDS has killed over 30 million people and left countless children orphaned, with no effective vaccine on the horizon. Less well known is that millions of cats also suffer and die from FIV/AIDS each year. Since the project concerns ways introduced genes can protect species against viruses, the knowledge and technology it produces might eventually assist conservation of wild feline species, all 36 of which are endangered.
The technique is called gamete-targeted lentiviral transgenesis -- essentially, inserting genes into feline oocytes (eggs) before sperm fertilization. Succeeding with it for the first time in a carnivore, the team inserted a gene for a rhesus macaque restriction factor known to block cell infection by FIV, as well as a jellyfish gene for tracking purposes. The latter makes the offspring cats glow green..."
Norton I: The First and Only Emperor of the United States
|5:24:34 PM, Saturday, September 10, 2011|
"From its adoption into the United States in 1850 up until the present day, California has always been a place where eccentricity is accepted, if not welcomed with open arms. Anyone who’s ever spent much time in West Hollywood or San Francisco can attest to that. Today, we’re going to take a look at one of California’s most notorious yet well-loved eccentrics.
He was a self-proclaimed aristocrat, even going so far as to declare himself Emperor of the United States and Protector of Mexico, indulging in the sort of monarchy nonsense that the country had spilled blood over less than a hundred years before. Yet in spite of it, when this Emperor finally died in 1880, almost thirty thousand people jammed the streets of San Francisco to attend his funeral. And in 1880, thirty thousand people represented over ten percent of the city’s population.
Exactly when Joshua Abraham Norton was born is a subject of some dispute. Various records and testimonies place his year of birth anywhere between 1814 and 1819, and his obituary cited his age as “about sixty-five.” Regardless of when he was born, it is known that Norton was born in London but spent most of his early life in South Africa.
Like many men in his time, Norton packed up and traveled to San Francisco in 1849. He financed the move with an inheritance of $40,000 from his father, and within a few years had managed to accumulate a tidy sum in the California real estate market.
Also like many men in his time, an ill-fated investment ate the lion’s share of Norton’s fortune. It wasn’t the gold rush that got him, nor his dabbling in real estate, but a gamble on a shipment of Peruvian rice, of all things. Since China had banned the export of rice due to famine, Norton figured that he could purchase a shipment of rice from Peru and sell it to Californians at an exorbitant cost. Unfortunately, by the time his shipment actually arrived, several other Peruvian ships had as well, and the price of rice dropped from thirty-six to three cents per pound. Norton fought hard to hold on to his property if nothing else, but his bank foreclosed on his holdings in order to cover the enormous rice debt..."
Phoenix Goddess Temple Raided as Alleged Brothel
|2:45:40 PM, Saturday, September 10, 2011|
"Arizona prosecutors have charged more than 30 people affiliated with the Phoenix Goddess Temple, a 10,000-square-foot alleged brothel that had been operating under the pretense of providing "religious" services for hundreds of dollars in cash "donations," police said.
"They were committing crimes under the guise of religious freedom," Phoenix police spokesman Steve Martos said. "It's a sad situation when people are trying to hide behind religion and church to commit a crime."
The "temple" had been operating in Phoenix since 2009, but authorities didn't become aware of it until residents began complaining. After a local newspaper visited the alleged brothel and published an in-depth story, police launched a six-month investigation culminating in the arrest of 18 people Wednesday. They are still hunting down the other 19.
It was the largest Arizona prostitution bust since authorities broke up the tri-state "Desert Divas" ring in 2008.
During the investigation, police discovered the Goddess Temple was operating another alleged house of prostitution in Sedona, Ariz., which was also raided Wednesday.
Goddess Temple founder Tracy Elise, known within her business as "Mystic Mother," was one of the 18 arrested Wednesday. She had also been involved with a similar alleged brothel in Seattle, Wash., that had been shut down in 2009..."

New Evidence for a Preferred Direction in Spacetime Challenges the Cosmological Principle
|11:06:00 PM, Friday, September 09, 2011|
"According to the cosmological principle, there is no special place or direction in the universe when viewed on the cosmic scale. The assumption enabled Copernicus to propose that Earth was not the center of the universe and modern scientists to assume that the laws of physics are the same everywhere. Due to the cosmological principle, scientists also assume that the universe is “homogeneous” - having a uniform structure throughout - and “isotropic” - having uniform properties throughout.
But a few recent studies have found the possible existence of cosmological anisotropy: specifically, that the universe’s expansion is accelerating at a faster rate in one direction than another. In the most recent study, scientists have analyzed data from 557 Type 1a supernovae and found, in agreement with some previous studies, that the universe’s expansion seems to be accelerating faster in the direction of a small part of the northern galactic hemisphere.
The researchers, Rong-Gen Cai and Zhong-Liang Tuo from the Chinese Academy of Sciences in Beijing, have posted their study at arXiv.org.
A valuable tool for cosmologists, Type 1a supernovae serve as “standard candles” due to their consistent peak luminosity, allowing researchers to measure their distance with high accuracy. Observations of these supernovae famously revealed in 1998 that the universe is not only expanding, but is doing so at an accelerating rate. And now, some observations of Type 1a supernovae at different locations in the sky hint that the acceleration is not uniform in all directions.
In their analysis, Cai and Tuo looked at the deceleration parameter, q0, to quantify the anisotropy level of the northern galactic and southern galactic hemispheres. As the scientists explain in their study, the direction with the smaller value of q0 is expanding faster than the direction with the larger value. The researchers analyzed the data using both a dynamical dark energy model and a standard model without dark energy, and found that both models revealed similar results: an anisotropy deviation of 0.76 and 0.79, respectively, and a preferred direction of (309°, 21°) and (314°, 28°), respectively. As noted by the Physics arXiv Blog, this direction of greatest acceleration is in the faint constellation of Vulpecula in the northern hemisphere..."
Imagining the Downside of Immortality
|10:08:12 PM, Friday, September 09, 2011|
"IMAGINE nobody dies. All of a sudden, whether through divine intervention or an elixir slipped into the water supply, death is banished. Life goes on and on; all of us are freed from fear that our loved ones will be plucked from us, and each of us is rich in the most precious resource of all: time.
Wouldn’t it be awful?
This is the premise of the TV series “Torchwood: Miracle Day,” a co-production of Starz and the BBC that has been running over the summer and ends in September. The “miracle” of the title is that no one dies anymore, but it proves to be a curse as overpopulation soon threatens to end civilization. The show is a nice twist on our age-old dream of living forever. And it is right to be pessimistic about what would happen if this dream were fulfilled — but for the wrong reasons. Materially, we could cope with the arrival of the elixir. But, psychologically, immortality would be the end of us.
The problem is that our culture is based on our striving for immortality. It shapes what we do and what we believe; it has inspired us to found religions, write poems and build cities. If we were all immortal, the motor of civilization would sputter and stop.
Poets and philosophers have long been attuned to the fact that the quest for immortality drives much of humanity’s peculiar ways. But only in recent decades has scientific evidence backed this up.
In a study that began in 1989, a group of American social psychologists found that just briefly reminding people that they would die had a remarkable impact on their political and religious views.
In their first experiment, the researchers recruited court judges from Tucson. Half the judges were reminded of their mortality (via an otherwise innocuous personality test) and half were not. They were then all asked to rule on a hypothetical case of prostitution similar to those they ruled on. The judges who had first been reminded of their mortality set a bond nine times higher than those who hadn’t (averaging $455 compared to $50)..."
'Invisible' World Discovered: Planet Alternately Runs Late and Early in Its Orbit, Tugged by Second Hidden World
|11:19:25 PM, Thursday, September 08, 2011|
"Usually, running five minutes late is a bad thing since you might lose your dinner reservation or miss out on tickets to the latest show. But when a planet runs five minutes late, astronomers get excited because it suggests that another world is nearby.
NASA's Kepler spacecraft has spotted a planet that alternately runs late and early in its orbit because a second, "invisible" world is tugging on it. This is the first definite detection of a previously unknown planet using this method. No other technique could have found the unseen companion.
"This invisible planet makes itself known by its influence on the planet we can see," said astronomer Sarah Ballard of the Harvard-Smithsonian Center for Astrophysics (CfA). Ballard is lead author on the study, which has been accepted for publication in The Astrophysical Journal.
"It's like having someone play a prank on you by ringing your doorbell and running away. You know someone was there, even if you don't see them when you get outside," she added.
Both the seen and unseen worlds orbit the Sun-like star Kepler-19, which is located 650 light-years from Earth in the constellation Lyra. The 12th-magnitude star is well placed for viewing by backyard telescopes on September evenings.
Kepler locates planets by looking for a star that dims slightly as a planet transits the star, passing across the star's face from our point of view. Transits give one crucial piece of information -- the planet's physical size. The greater the dip in light, the larger the planet relative to its star. However, the planet and star must line up exactly for us to see a transit.
The first planet, Kepler-19b, transits its star every 9 days and 7 hours. It orbits the star at a distance of 8.4 million miles, where it is heated to a temperature of about 900 degrees Fahrenheit. Kepler-19b has a diameter of 18,000 miles, making it slightly more than twice the size of Earth. It may resemble a "mini-Neptune," however its mass and composition remain unknown..."
