An Illustrated History Of Gas Masks

The gas mask has a history that dates back thousands of years, though it wasn't until World War I that it became nightmare fodder for Doctor Who and countless other stories. Here is a sometimes terrifying history of the gas mask, from its beginnings through the present day.

Mustache Transplant

Mustache-challenged? Do you feel like less of a man because you cannot grow a proper upper lipholstery? Fear not! Head over to Turkey, where you can get a mustache transplant:

The procedure uses a technique called follicle-hair extraction, in which doctors remove clusters of hair from the more hirsute areas of the body and implant them along the lip or cheeks to magnify a mustache or beef-up a beard.
Performed under local anesthetic, the surgery takes around five hours and can cost up to $5,000, cosmetic surgeons say. Tourism agencies have begun offering "transplant packages" combining facial-hair operations with a shopping vacation in Istanbul or beachside retreat on the Mediterranean coast.

Racial Tolerance Around the World

The map above is based on information from the World Values Survey, which does ongoing research. The data from a single question was used to gauge racist attitudes around the world. Two Swedish economists used the data for a study to determine if there was any correlation between economic freedom and racism in different countries.

Among the dozens of questions that World Values asks, the Swedish economists found one that, they believe, could be a pretty good indicator of tolerance for other races. The survey asked respondents in more than 80 different countries to identify kinds of people they would not want as neighbors. Some respondents, picking from a list, chose “people of a different race.” The more frequently that people in a given country say they don’t want neighbors from other races, the economists reasoned, the less racially tolerant you could call that society. (The study concluded that economic freedom had no correlation with racial tolerance, but it does appear to correlate with tolerance toward homosexuals.)

Max Fisher used the raw data from the study to create the map. It has been pointed out that the survey results may be affected by cultural differences in answering survey questions honestly. At the Washington Post, you can enlarge the map and read more about the project. More

Mesmerizing Sun Halo

Last Tuesday, residents of New York and the surrounding area were privy to a really amazing celestial treat; it's called a Sun Halo, and one spent some time today hovering over The Big Apple and making people wonder if Martians were finally invading.

A halo is a type of optical phenomenon that can happen around the sun or moon. It's also referred to as a 22-degree halo because it forms a ring exactly 22-degrees from the sun. In order for a Sun halo to happen, a thin veil of high-level clouds has to put some hexagonal ice crystals at exactly right spot.

Why Your Ears Pop

(And What To Do If They Don't)

Ear popping - also called ear clearing - is any of various maneuvers to equalize the pressure in the middle ear with the outside pressure, by letting air enter along the Eustachian tubes, as this does not always happen automatically when the pressure in the middle ear is lower than the outside pressure.

This need can arise in scuba diving, skydiving, fast descent in an aircraft, and being put into pressure in a caisson or similar pressure-bearing structure, or sometimes even simply traveling at fast speeds in an automobile. When that happens, learn how to fix it.

Teenage chemistry enthusiast won't be charged with felony, will go to space camp

Kiera Wilmot — the Florida 16-year-old who created a small explosion just outside her school before classes started by mixing cleaning solution and tin foil (she was just curious, nobody was harmed) — will not be charged with a felony, after all. Florida State Attorneys dropped the charges against Wilmot yesterday. After her case garnered national attention, she ended up with a lawyer who has defended her mostly for free. There's no word yet on whether she'll be allowed to return to the school that expelled her and pressed charges in the first place.
In the meantime, the Internet has created a nice happy ending here. Homer Hickam — the writer and former NASA engineer whose memoir is the basis of the movie October Sky — started a Crowdtilt campaign to send Wilmot and her twin sister Kayla to the Advanced Space Academy program at the U.S. Space Camp in Huntsville, Ala.. The cost of space camp can run upwards of $1200. Hickam paid for Kiera Wilmot to go and the Crowdtilt campaign raised the other $1200 for her sister, plus extra money for their travel expenses. The campaign hit its $2500 goal in just two days and is now up to $2920. Hickam says the extra money is going to the girls' mother.
A second Crowdtilt campaign raised more than $8000 for a Kiera Wilmot Defense Fund. Now that the charges have been dropped, that money will go into a trust, to pay the few legal expenses the family does have and to cover costs associated with Wilmot's education — especially since it's still unclear whether she'll be allowed back into the local public school.
Good job, Internet!

Scientists Managed to Clone Human Embryos

Donor egg held by pipette prior to nuclear extraction.

A significant, and undoubtedly controversial, milestone in stem cell therapy was reached yesterday. Scientists at the Oregon Health and Science University managed to achieve the Holy Grail of stem cell research: they've cloned a human embryo.

OHSU cell biologist Shoukhrat Mitalipov led a team of 23 scientists who methodically culled the lessons learned from stem cell research on amphibians, mice and rhesus monkeys — as well as from the abundant failures of others in the field. They devised a welter of new techniques to use the DNA of a fully formed skin cell in its most primitive embryonic form. [...]
In past efforts to coax such an assemblage of components to life, researchers have burned through dozens of donor eggs without getting any embryos even to the 16-cell stage at which stem cells become a remote possibility.
This time, the researchers said their methods were so efficient that they could create at least one embryonic stem cell line from each batch of eggs donated by 10 female volunteers. In one case, a single donor produced eight eggs of such exceptional quality that researchers were able to derive four embryonic stem cell lines.

Some hailed the development as an important advance in the paving the way to treat a range of diseases, but others feared that it's one step closer to cloning humans.

Why science needs silly-sounding research

Earlier this week, scientists announced that they'd found evidence suggesting malaria-carrying mosquitoes are more attracted to the smell of human flesh than healthy mosquitoes. This research — which, I'm sure you'll agree, has some important implications — grew out of research that could be deemed very silly. In fact, this new finding was built on IgNobel-winning research published back in 1996, which found that malaria mosquitoes are attracted to the smell of stinky cheese.

Kangaroo in plaster cast after breaking her arm

A kangaroo has her arm in plaster after breaking it in an accident at her zoo enclosure in Munich, Germany. Keepers brought in vets after noticing that poorly Helena - a red kangaroo - was clearly in pain and cradling her arm.

"She was holding her arm and looked in pain. We knew something must be wrong." said a zoo spokesman. "After tranquilizing her we discovered she had a fracture in her left arm which was reset and covered in a plaster cast,"

"It is not stopping her hopping around and playing with the other kangaroos. The support means she is no longer in pain. She is very lively and enjoys jumping around.

"A lot of visitors have asked us how she hurt her arm. We don't know but think she must have fell whilst playing. It will come off in a few weeks and we're expecting her to make a full recovery," they added.
