A small band of particle-seeking scientists at Yale and Harvard has established a new benchmark for the electron's almost perfect roundness, raising doubts about certain theories that predict what lies beyond physics' reigning model of fundamental forces and particles, the Standard Model.
 
 
"We know the Standard Model does not encompass everything," said Yale physicist David DeMille, who with John Doyle and Gerald Gabrielse of Harvard leads the ACME collaboration, a team using a strikingly different method to detect some of the same types of particles sought by huge experiments at the Large Hadron Collider (LHC) in Europe. "Like our LHC colleagues, we're trying to see something in the lab that's different from what the Standard Model predicts."

ACME is looking for new particles of matter by measuring their effects on the shape of the electron, the negatively charged subatomic particle orbiting within every atom.  
 
In research published Dec. 19 in Science Express, the team reported the most precise measurement to date of the electron's shape, improving it by a factor of more than 10 and showing the particle to be rounder than predicted by some extensions of the Standard Model, including some versions of Supersymmetry.
 
This theory posits new types of particles that help account, for example, for dark matter, a mysterious substance estimated to make up most of the universe.  Researchers said they have shown that the electron's departure from spherical perfection—if it exists at all—must be smaller than predicted by many theories proposing particles the Standard Model doesn't account for. If the electron's shape is too round, many of these theories will be proven wrong, they said.
 
Many variants of Supersymmetry predict a less round shape for the electron than the ACME team found experimentally. If the particles predicted by those versions of Supersymmetry existed, they would have caused greater deformation of the electron, researchers said.

The ACME project looked for a particular deformation in the electron's shape known as an electric dipole moment.  "You can picture the dipole moment as what would happen if you took a perfect sphere, shaved a thin layer off one hemisphere and laid it on top of the other side," said DeMille, who helped establish previous landmark limits in electron deformation. "The thicker the layer, the larger the dipole moment. Now imagine an electron blown up to the size of the earth. Our experiment would have been able to see a layer 10,000 times thinner than a human hair, moved from the southern to the northern hemisphere. But we didn't see it, and that rules out some theories."

The ACME researchers measured the dipole moment using electrons inside the polar molecule thorium monoxide. The molecule's properties amplify the electron's deformation and diminish the possibility of effects that could fool researchers into thinking they had seen a tiny deformation when none exists.

"It is amazing that some of these predicted supersymmetric particles would squeeze the electron into a kind of egg shape," said Harvard's Doyle. "Our experiment is telling us that this just doesn't happen at our level of sensitivity."

Gabrielse, also of Harvard, said: "It's unusual and satisfying that the exquisite precision achieved by our small team in a university lab probes the most fundamental building block of our universe at a sensitivity that complements what is being achieved by thousands at the world's largest accelerator."

Inside the Saudi 9/11 coverup

After the 9/11 attacks, the public was told al Qaeda acted alone, with no state sponsors.
But the White House never let it see an entire section of Congress’ investigative report on 9/11 dealing with “specific sources of foreign support” for the 19 hijackers, 15 of whom were Saudi nationals.
It was kept secret and remains so today.
President Bush inexplicably censored 28 full pages of the 800-page report. Text isn’t just blacked-out here and there in this critical-yet-missing middle section. The pages are completely blank, except for dotted lines where an estimated 7,200 words once stood (this story by comparison is about 1,000 words).
A pair of lawmakers who recently read the redacted portion say they are “absolutely shocked” at the level of foreign state involvement in the attacks.
Reps. Walter Jones (R-NC) and Stephen Lynch (D-Mass.) can’t reveal the nation identified by it without violating federal law. So they’ve proposed Congress pass a resolution asking President Obama to declassify the entire 2002 report, “Joint Inquiry Into Intelligence Community Activities Before and After the Terrorist Attacks of September 11, 2001.”
Some information already has leaked from the classified section, which is based on both CIA and FBI documents, and it points back to Saudi Arabia, a presumed ally.
The Saudis deny any role in 9/11, but the CIA in one memo reportedly found “incontrovertible evidence” that Saudi government officials — not just wealthy Saudi hardliners, but high-level diplomats and intelligence officers employed by the kingdom — helped the hijackers both financially and logistically. The intelligence files cited in the report directly implicate the Saudi embassy in Washington and consulate in Los Angeles in the attacks, making 9/11 not just an act of terrorism, but an act of war.
Modal Trigger
The findings, if confirmed, would back up open-source reporting showing the hijackers had, at a minimum, ties to several Saudi officials and agents while they were preparing for their attacks inside the United States. In fact, they got help from Saudi VIPs from coast to coast:
LOS ANGELES: Saudi consulate official Fahad al-Thumairy allegedly arranged for an advance team to receive two of the Saudi hijackers — Khalid al-Mihdhar and Nawaf al-Hazmi — as they arrived at LAX in 2000. One of the advance men, Omar al-Bayoumi, a suspected Saudi intelligence agent, left the LA consulate and met the hijackers at a local restaurant. (Bayoumi left the United States two months before the attacks, while Thumairy was deported back to Saudi Arabia after 9/11.)
SAN DIEGO: Bayoumi and another suspected Saudi agent, Osama Bassnan, set up essentially a forward operating base in San Diego for the hijackers after leaving LA. They were provided rooms, rent and phones, as well as private meetings with an American al Qaeda cleric who would later become notorious, Anwar al-Awlaki, at a Saudi-funded mosque he ran in a nearby suburb. They were also feted at a welcoming party. (Bassnan also fled the United States just before the attacks.)
WASHINGTON: Then-Saudi Ambassador Prince Bandar and his wife sent checks totaling some $130,000 to Bassnan while he was handling the hijackers. Though the Bandars claim the checks were “welfare” for Bassnan’s supposedly ill wife, the money nonetheless made its way into the hijackers’ hands.
Other al Qaeda funding was traced back to Bandar and his embassy — so much so that by 2004 Riggs Bank of Washington had dropped the Saudis as a client.
The next year, as a number of embassy employees popped up in terror probes, Riyadh recalled Bandar.
“Our investigations contributed to the ambassador’s departure,” an investigator who worked with the Joint Terrorism Task Force in Washington told me, though Bandar says he left for “personal reasons.”
FALLS CHURCH, VA.: In 2001, Awlaki and the San Diego hijackers turned up together again — this time at the Dar al-Hijrah Islamic Center, a Pentagon-area mosque built with funds from the Saudi Embassy. Awlaki was recruited 3,000 miles away to head the mosque. As its imam, Awlaki helped the hijackers, who showed up at his doorstep as if on cue. He tasked a handler to help them acquire apartments and IDs before they attacked the Pentagon.
Awlaki worked closely with the Saudi Embassy. He lectured at a Saudi Islamic think tank in Merrifield, Va., chaired by Bandar. Saudi travel itinerary documents I’ve obtained show he also served as the ­official imam on Saudi Embassy-sponsored trips to Mecca and tours of Saudi holy sites.
Most suspiciously, though, Awlaki fled the United States on a Saudi jet about a year after 9/11.
As I first reported in my book, “Infiltration,” quoting from classified US documents, the Saudi-sponsored cleric was briefly detained at JFK before being released into the custody of a “Saudi representative.” A federal warrant for Awlaki’s arrest had mysteriously been withdrawn the previous day. A US drone killed Awlaki in Yemen in 2011.
HERNDON, VA.: On the eve of the attacks, top Saudi government official Saleh Hussayen checked into the same Marriott Residence Inn near Dulles Airport as three of the Saudi hijackers who targeted the Pentagon. Hussayen had left a nearby hotel to move into the hijackers’ hotel. Did he meet with them? The FBI never found out. They let him go after he “feigned a seizure,” one agent recalled. (Hussayen’s name doesn’t appear in the separate 9/11 Commission Report, which clears the Saudis.)
SARASOTA, FLA.: 9/11 ringleader Mohamed Atta and other hijackers visited a home owned by Esam Ghazzawi, a Saudi adviser to the nephew of King Fahd. FBI agents investigating the connection in 2002 found that visitor logs for the gated community and photos of license tags matched vehicles driven by the hijackers. Just two weeks before the 9/11 attacks, the Saudi luxury home was abandoned. Three cars, including a new Chrysler PT Cruiser, were left in the driveway. Inside, opulent furniture was untouched.
Democrat Bob Graham, the former Florida senator who chaired the Joint Inquiry, has asked the FBI for the Sarasota case files, but can’t get a single, even heavily redacted, page released. He says it’s a “coverup.”
Is the federal government protecting the Saudis? Case agents tell me they were repeatedly called off pursuing 9/11 leads back to the Saudi Embassy, which had curious sway over White House and FBI responses to the attacks.
Just days after Bush met with the Saudi ambassador in the White House, the FBI evacuated from the United States dozens of Saudi officials, as well as Osama bin Laden family members. Bandar made the request for escorts directly to FBI headquarters on Sept. 13, 2001 — just hours after he met with the president. The two old family friends shared cigars on the Truman Balcony while discussing the attacks.
Bill Doyle, who lost his son in the World Trade Center attacks and heads the Coalition of 9/11 Families, calls the suppression of Saudi evidence a “coverup beyond belief.” Last week, he sent out an e-mail to relatives urging them to phone their representatives in Congress to support the resolution and read for themselves the censored 28 pages.
Astonishing as that sounds, few lawmakers in fact have bothered to read the classified section of arguably the most important investigation in US history.
Granted, it’s not easy to do. It took a monthlong letter-writing campaign by Jones and Lynch to convince the House intelligence panel to give them access to the material.
But it’s critical they take the time to read it and pressure the White House to let all Americans read it. This isn’t water under the bridge. The information is still relevant ­today. Pursuing leads further, getting to the bottom of the foreign support, could help head off another 9/11.
As the frustrated Joint Inquiry authors warned, in an overlooked addendum to their heavily redacted 2002 report, “State-sponsored terrorism substantially increases the likelihood of successful and more ­lethal attacks within the United States.”
Their findings must be released, even if they forever change US-Saudi relations. If an oil-rich foreign power was capable of orchestrating simultaneous bulls-eye hits on our centers of commerce and defense a dozen years ago, it may be able to pull off similarly devastating attacks today.
Members of Congress reluctant to read the full report ought to remember that the 9/11 assault missed its fourth target: them.

Government Scientists Create Crude Oil from Algae in Minutes

By Adam Clark Estes at Gizmo magazine.  Original post at

Be excited, Earthlings, because science has a surprise for you. Engineers at the Department of Energy's Pacific Northwest National Laboratory have devised a way to turn algae into crude oil in less than an hour. That oil can then be refined into gasoline that can run engines.
 
Excited yet? Try wrapping your head around the implications of a breakthrough like this. As one of the most plentiful lifeforms on the planet, algae is a perfect candidate for conversion to biofuel. It's especially good because the energy is packed pretty tightly into that green sludge. To replace all of the petroleum in the United States with algae fuel, you'd need a farm that took up just 0.42 percent of the country's landmass. By comparison, it would take up half of the United States to grow enough soybeans to replace petroleum with biodiesel.
 
Algae fuel is not a new idea, of course, and this is not the first time scientists have turned algae into fossil fuel. It is the first time they've done it so effortlessly and so quickly, however. Other methods require too much time and energy for the conversion to make sense as a petroleum replacement. The new process solves that problem. "It's a bit like using a pressure cooker, only the pressures and temperatures we use are much higher," said Douglas Elliott, who led the research. "In a sense, we are duplicating the process in the Earth that converted algae into oil over the course of millions of years. We're just doing it much, much faster."
 
This magic gas could be coming to your local gas station sooner than you think. The Department of Energy already has a partner, Genifuel, working on commercializing the process and making the algae fuel competitive with what's already on the market. But, boy, is it going to be futuristic when you pull up to a gas station and pump your tank full of algae. Talk about going green.

Why Are Female Redheads Sexualized and Male Redheads Reviled?

Prince Harry: Heartthrob or mutant?

“Red hair is a woman's game,” Tom Robbins writes in his 1998 GQ essay “Ode to Redheads.” “The harsh truth is, most red-haired men look like blonds who've spoiled from lack of refrigeration,” Robbins says. “They look like brown-haired men who've been composted. Yet that same pigmentation that on a man can resemble leaf mold or junk yard rust, a woman wears like a tiara of rubies.” That’s a grim view of redheaded men—and it was coming from a fellow ginger.

This month, British photographer Thomas Knights—also a redhead—hopes to turn that stereotype on its head with “Red Hot,” a photo exhibition featuring “a cast of high profile and good-looking red headed males,” shot giving torrid looks in topless poses. Male redheads “are completely emasculated and desexualised in popular culture,” Knights told the Guardian. “The main thing for me is the huge polarisation between the way our society perceives ginger men and ginger women.”

Why do we see redheaded women as rubies and redheaded men as rusted? Perhaps because the rarity of the shade—redheads benefit (or suffer) from two doses of a recessive gene that causes a mutation in the protein that regulates melanin—has inspired a historical association with difference and deviance. In the Middle Ages, red hair was taken as a sign of witchcraft and vampirism; Elizabethan actors portrayed Jewish characters with false noses and red wigs; and Judas is often painted with a long, fiery mane. For women, the perception of deviance is often eroticized. The sins attributed to women are largely sexual ones. And the expression of this sexual deviance is often rooted in the follicles. "Hair itself is symbolically fraught,” University of Texas myth scholar Betty Sue Flowers told the Washington Post in 2002. “Hair equals sex. Why do women have to cover their hair in churches? There are more rules about hair than anything else except covering the genitals. It's so connected with spiritual and religious taboos." 

The result? Red is now the shade of choice for contemporary femme fatales, from Jessica Rabbit to Joan Holloway. Meanwhile, ginger boys are ridiculed and sexually marginalized; in 2011, a Danish-based international sperm bank stopped collecting donations from redheads, saying it was “drowning in semen” from unpopular ginger donors. Try to think of a famous redheaded man who isn’t Damian Lewis or a prince, and you get a lot of clowns: Conan O'Brien, Louis CK, Carrot Top.

The myth of the sexy redhead and her deviant brother was constructed by male apostles, playwrights, and painters. Some women buy that version of sexuality, too: Knights interviewed one woman who willingly dates a ginger man but still fears the consequences: "Of course I'm going to love it, but I don't want a ginger baby," she said. But projects like Knights' show how easy it is to revert that centuries-old idea by taking a few photos from a different perspective (and recruiting some exceptionally good-looking gingers to pose). “Someone recently asked me, ‘What’s so special about red hair?’ ” Knights told The Cut. “Well, nothing. It’s not special—it’s just equal. All I want is for ginger men to be on a level playing field.”

It’s a Christmas Miracle! New Study Shows That 1% of Women Claim to Have Virgin Births

It’s a Christmas Miracle! New Study Shows That 1% of Women Claim to Have Virgin Births

David Strumfels -- though probably a hoax, it isn't physiologically/biologically impossible and probably does happen at least on very rare occasions, just as it does with many other animals.

It’s a Christmas Miracle! New Study Shows That 1% of Women Claim to Have Virgin Births

***Update***: BMJ is known to write parody papers in their Christmas edition. So while the material below is plausible, take it with a grain of salt. It’s likely a hoax.
(In a related study, 1% of women lie to researchers.)

The headline’s serious, though it requires a little more explanation.

A new report published in the Christmas edition of BMJ shows that 0.8% of women who became pregnant also claimed, at the time when the child would have been conceived, that they were not having sexual intercourse:

Based on interviews with 7,870 women and girls ages 15-28, 45 of the 5,340 pregnancies in this group through the years — 0.8 per cent — occurred in women who reported that they conceived independent of men. The figure does not include pregnancies that result from in vitro fertilization or other assisted reproductive technology.

The girls were 12 to 18 years old when they entered the study in the 1994-95 school year and were interviewed periodically about their health and behaviour over 14 years, including via computer as a way to encourage them to be candid when answering questions about their sexual history.

The 45 women and girls who became pregnant despite, according to what they told interviewers, being virgins at the time of conception differed in several ways from peers who acknowledged that men had had a role in their procreation.

So why would they lie…?

Turns out nearly a third of them had signed pledges saying they wouldn’t have sex before marriage. Hell, they may have been wearing purity rings as they got it on.

They “Virgin Birthers” were also “more likely than non-virgins to say their parents never or rarely talked to them about sex and birth control.”

They were also less likely to know how to use a condom.

And, I’m assuming, they wanted to sound like they were chaste, even to the researchers who didn’t know them, and even though the evidence to the contrary was growing right inside of them. (It’s also possible they didn’t realize that they technically had sex.)

I love the conclusion:

The researchers found that although the mothers in question were more likely to have boys than girls and to be pregnant during the weeks leading up to Christmas, neither similarity to the Virgin Mary was statistically significant.

You’ll be interested in knowing there were a few “virgin fathers” as well.

I've Been to VietNam But Never Saw This


I stole this from Google+.  It's in Vietnam, probably in the north somewhere.  Now I've been to VN, and saw some amazing things, but nothing like this.
