The Physics of Fire Walking

The Physics of Firewalking -- io9

Last Thursday, close to two dozen participants at a motivational seminar hosted by Tony Robbins suffered burns on their feet, while attempting to tromp across lanes of red-hot coals. So what did these burn victims do wrong?

The Associated Press reports that most of those injured sustained second- and even third-degree burns, but event organizers have since released a statement claiming that 6,000 attendees walked across the coals that day and emerged from the embers unscathed. Educate yourself on the physics of firewalking — here's what you need to know to keep from getting burned.

Free Internet For 7 Years From Google

Google Is Now America’s Most Awesome ISP -- Geek Mom

Kansas City is about half an hour from my house, taunting me with fast download speeds.

After a summer of waiting, Google finally emerged with details on their new Kansas City Fiber network. The price for Google Internet starts at free. That’s right, for the $300 installation fee, Google will give you free Internet at “today’s speeds” for at least 7 years. If you’re used to thinking of these speeds as fast, take a gander at this comparison and then imagine seven years of technology innovation.

A Working Assault Rifle Made With a 3-D Printer -- Popular Science

Making weapons at home just got much easier.

Get ready. It's now possible to print weapons at home.

An amateur gunsmith, operating under the handle of "HaveBlue" (incidentally, "Have Blue" is the codename that was used for the prototype stealth fighter that became the Lockheed F-117), announced recently in online forums that he had successfully printed a serviceable .22 caliber pistol.

Despite predictions of disaster, the pistol worked. It successfully fired 200 rounds in testing.

Crucially, the 650ft, four-masted UK Flagship will not be funded by taxpayers’ money, instead drawing on donations from businesses, philanthropists and the public.

Mr Clegg said: ‘This is directly in line with Britain’s proud naval tradition which stretches back hundreds of years. Our country has always been at the forefront of trade, exploration and scientific research and the UK Flagship can help us to continue to be so.

An Aids Cure?

Two More Men With HIV Now Virus-Free. Is This A Cure? -- NBC

Two men unlucky enough to get both HIV and cancer have been seemingly cleared of the virus, raising hope that science may yet find a way to cure for the infection that causes AIDS, 30 years into the epidemic.

The researchers are cautious in declaring the two men cured, but more than two years after receiving bone marrow transplants, HIV can't be detected anywhere in their bodies. These two new cases are reminiscent of the so-called "Berlin patient," the only person known to have been cured of infection from the human immunodeficiency virus.

My Comment: They are getting there .... albeit slowly.

Captain Morgan's Treasure

The Underwater Archaeologists Searching For Captain Morgan -- Popular Science

Off the coast of Panama, a team of archaeologists uncovers a ship that may have belonged to one of the most famous pirates who ever lived.

So this is what a pirate's sword feels like.

I wrap my hands around the straight iron blade. It's probably a 17th-century rapier, I'm told, but it'd hard to know for sure. The handle is missing, and though I can see and feel its fuller groove, a layer of sea shells and some sort of hardened concretion cover the blade's finer details. "That's either calcium carbonate or coralline," Texas State University archaeologist Fritz Hanselmann tells me as he takes the blade and places it in a makeshift holder his crew had just MacGyvered from a metal CD rack, rebar, and scraps of a yoga mat.

My Comment: Not a story about rum .... but definitely a story about a rum company helping to boost it's brand.

Attack Of The Vampire Sun!

Attack Of The Vampire Sun! Astronomers Spot Binary System Where One Star Sucks The Life Out Of Another -- Daily Mail

The Universe is a diverse place, and many stars are quite unlike the Sun.

Now an international team has used the Very Large Telescope in Chile to study what are known as O-type stars, which have very high temperature, mass and brightness.

These stars have short and violent lives and play a key role in the evolution of galaxies. They are also linked to extreme phenomena such as 'vampire stars', where a smaller companion star sucks matter off the surface of its larger neighbour.

Absorbent Paint Could Soak Up Chemical Weapons, Protecting Vehicle Occupants From Deadly Gas -- Popular Science

Syria’s regime announced for the first time this week that it has chemical weapons, and stands ready to use them if attacked. A new type of paint could potentially guard against it, protecting tanks and armored vehicles with a special chemical-absorbing topcoat.

Scientists at the UK’s Defence Science and Technology Laboratory, like a British DARPA, worked with a company called AkzoNobel to develop the paint. It contains super absorbent silica gel, the same stuff that comes in those little bead-packets inside new shoeboxes and bags. The material can absorb chemicals, like maybe nerve gas, before they could reach a vehicle’s interior.

My Comment: A simple but effective counter-measure. This is smart.

There Goes The Paperwork As Tablets Now Rule In The White House

President Obama Wants Smartphones, Tablets To Improve Intel Monitoring -- Aol Defense

WASHINGTON: When the Presidential Daily Briefing occurs, a top intelligence official traditionally hands the president a folder with a sheaf of paper inside. The president may read what's inside or have it presented by the intelligence official. Then comes question time, when the chief executive and commander in chief can ask how reliable a source is or question the assumptions of an analysis he's just read.

But that will change. The president and his top officials want and will get a single mobile device allowing them to access highly classified and unclassified data wherever they are. The early fruits of the intelligence community's early efforts to do that are visible in the photo above. It shows President Obama in the Oval Office on January 31 using a technically neutered tablet as part of the Presidential Daily Briefing.

My Comment: I still prefer paper .... but digital is what the young (including this President) now want.

How The Next Great Pandemic Will Be Spread

When Contagion Strikes, It's Honolulu You Should Avoid -- The Guardian

MIT researchers have analysed which airport hubs would be key to spreading a virulent disease, with some surprising results

When the next outbreak of Sars or Swine flu hits, New York's John F Kennedy airport and Los Angeles's airports will likely be the key spreaders of disease, according to a new study. But while the influence of these super-hubs may not come as much of a surprise, the third most outbreak-friendly airport in the states is far smaller, and far less obvious – Honolulu International.

In a paper published Monday in the journal PLoS One, a team of researchers from MIT outlined a new computer model that predicts how the 40 largest American airports may contribute to the diffusion of contagious disease within the first few days of a potential epidemic.

Are Dolphins Math Geniuses?

Dolphins May Be Maths Geniuses -- ABC News (Australia)

Dolphins may use complex nonlinear maths when hunting, according to a new study that suggests they could be far more skilled than was ever thought possible before.

Inspiration for the new study, published in the latest Proceedings of the Royal Society A, came after lead author Tim Leighton watched an episode of the Discovery Channel's Blue Planet series and saw dolphins blowing multiple tiny bubbles around prey as they hunted.

Former astronaut loses 17-month battle against cancer; hailed as role model.

The first American woman to go into space, Sally Ride, died Monday after a 17-month battle against pancreatic cancer, her company said.

Ride made history in 1983 as a crew member on the space shuttle Challenger, breaking the gender barrier for U.S. spaceflight. Soviet cosmonaut Valentina Tereshkova became the first woman in space in 1963, but it took another 20 years for NASA to follow suit.

Who Really Invented The Internet?

Xerox PARC headquarters.

Who Really Invented The Internet? -- Gordon Crovitz, Wall Street Journal

Contrary to legend, it wasn't the federal government, and the Internet had nothing to do with maintaining communications during a war.

A telling moment in the presidential race came recently when Barack Obama said: "If you've got a business, you didn't build that. Somebody else made that happen." He justified elevating bureaucrats over entrepreneurs by referring to bridges and roads, adding: "The Internet didn't get invented on its own. Government research created the Internet so that all companies could make money off the Internet."

It's an urban legend that the government launched the Internet. The myth is that the Pentagon created the Internet to keep its communications lines up even in a nuclear strike. The truth is a more interesting story about how innovation happens—and about how hard it is to build successful technology companies even once the government gets out of the way.

My Comment: I recall reading in the 1980s an autobiography on Steve Jobs where he was boasting that many of his ideas (the use of the mouse, the mac, ethernet, etc.) .... all came came from Xerox Parc.

Drug-Resistant HIV Increasing In Sub-Saharan Africa

Monitoring of patients helps in detecting drug resistance

Drug-Resistant HIV 'On Increase' In Sub-Saharan Africa -- BBC

Drug-resistant HIV has been increasing in parts of sub-Saharan Africa over the last decade, according to experts writing in the Lancet.

Studies on 26,000 untreated HIV-positive people in developing countries were reviewed by the team.

They said resistance could build up if people fail to stick to drug regimes, and because monitoring could be poor.

A UK HIV organisation said resistance was a serious problem in Africa where alternative treatments were lacking.

My Comment: People failing to stick to drug regimes is probably the number one cause.
