Deadly Bacteria Defy Drugs, Alarming Doctors

A new category of bugs becomes more resistant to treatment, and their toll -- which already includes a Brazilian beauty queen -- is expected to rise.

From the L.A. Times:

When Ruth Burns had surgery to relieve a pinched nerve in her back, the operation was supposed to be an "in-and-out thing," recalled her daughter, Kacia Warren.

But Burns developed pneumonia and was put on a ventilator. Five days later, she was discharged -- only to be rushed by her daughter to the hospital hours later, disoriented and in alarming pain.

Seventeen days after the surgery, the 67-year-old nurse was dead.

Burns had developed meningitis -- an infection of the fluid that surrounds the spinal cord and brain. The culprit wasAcinetobacter baumannii, a bug that preys on the weak in hospitals. Worse, it was a multi-drug-resistant strain.

Prosecution Drops Some Charges Against the Pirate Bay

From The Danger Room:

STOCKHOLM — Prosecutors dropped half of the charges in the landmark trial of The Pirate Bay file sharing site Tuesday, leaving observers stunned and prompting questions about the government's preparedness in the long-awaited criminal proceeding.

"I will drop all charges that relate to producing infringing copies and will hence restrict the prosecution to the act of making works available to the public," prosecutor Hakan Roswall announced at the opening of the second day of the trial. "When I talk about making something available to the public I mean making available torrent files."

At an intermission, Roswall refused to clarify the change of heart to reporters. "As you can see I have a lot of other things to think about," he said. "There will be new adjusted charges distributed on paper tomorrow, Wednesday."

Race For 'God Particle' Heats Up

Lyn Evans says the magnet incident was a real setback for Cern

From The BBC:

Europe's particle physics lab, Cern, is losing ground rapidly in the race to discover the elusive Higgs boson, or "God particle", its US rival claims.

The particle, whose existence has been predicted by theoreticians, would help to explain why matter has mass.

Finding the Higgs is a major goal of Cern's Large Hadron Collider (LHC).

But the US Fermilab says the odds of its Tevatron accelerator detecting the famed particle first are now 50-50 at worst, and up to 96% at best.

Both machines hope to see evidence of the Higgs by colliding sub-atomic matter at very high speeds. If it exists, the Higgs should emerge from the debris.

Hansen On “Death Trains” And Coal And CO2

From Watts Up With That?

NASA’s Dr. James Hansen once again goes over the top. See his most recent article in the UK Guardian. Some excerpts:

“The trains carrying coal to power plants are death trains. Coal-fired power plants are factories of death.”

And this:

Clearly, if we burn all fossil fuels, we will destroy the planet we know. Carbon dioxide would increase to 500 ppm or more.

Only one problem there Jimbo, CO2 has been a lot higher in the past. Like 10 times higher.

IBM Files Patent for Bullet Dodging Bionic Body Armor

From Tech Fragments:

IBM has filed a patent (US 7484451) for Bionic Body Armor, that could essentially allow us to dodge bullets like Neo in The Matrix. The armor would scan areas for incoming projectiles and when one is detected the system would deliver a shock to the muscles causing a swift reflexive action away from the projectile. Here's what the patent describes the body armor as:

From FOX News/Space:

Could an alien astronomer have detected life on Earth during an ice age?

Recent work has calculated how past climate extremes affected the light reflected from vegetation out into space. The results could give hope to our own search for life on distant worlds.

From far away, our planet is a single faint speck of light in the sky. Although we have sent radio messages out to potential extraterrestrial listeners, none of these signals have traveled more than a few tens of light years.

Stem Cells In Hair Follicles Point To General Model Of Organ Regeneration

Deep roots. For a hair follicle to begin a new phase of growth, an elusive group of cells called the hair germ (bright red) must be activated. This progression of images shows that the hair germ begins proliferating (green) before other cells do, suggesting a two-step mechanism. (Credit: Image courtesy of Rockefeller University)

From Science Daily:

ScienceDaily (Feb. 16, 2009) — Most people consider hair as a purely cosmetic part of their lives. To others, it may help uncover one of nature’s best-kept secrets: the body’s ability to regenerate organs. Now, new research from Rockefeller University gets to the root of the problem, revealing that a structure at the base of each strand of hair, the hair follicle, uses a two-step mechanism to activate its stem cells and order them to divide.

The mechanism provides insights into how repositories of stem cells may be organized in other body tissues for the purpose of supporting organ regeneration.

Blacksmithing 101: How To Make A Forge And Start Hammering Metal

PM editors Roy Berendsohn (left) and Mike Allen (right) have framed houses and built race cars—but forge steel in the garage? That was something new.

From Popular Mechanics:

PM's home and auto editors took a weekend out to teach themselves how to heat and hammer metal the old-fashioned way. They started by ordering an anvil and making their own blacksmith forge. The sparks flew from there. Click here to download an updated version of the forge plans published in Popular Mechanics in 1941.

If you want to work with metal, there’s one thing you have to confront: You need heat. With it, you can make the toughest metal submit to your will. Without it, you’ll never gain full mastery over this stubborn material.

Over the years, I have been frustrated by my inability to work hot steel. I’ve bolted metal together, welded it and soldered it. But I couldn’t shape it, and so large swaths of the mechanical realm were off-limits to me.

But blacksmithing never felt alien. My father is a metallurgist, descended from generations of 19th-century blacksmiths and born in Germany to shipbuilders whose forges scattered sparks over the shores of the Elbe River and the North Sea. I grew up in rural Connecticut among Yankee mechanics who could forge anything, machine anything, build anything, fix anything—and I’ve been trying to live up to those old-timers’ standards all my life. It wasn’t hard to finally decide to take another step, and teach myself some blacksmithing skills.

Women Less Tolerant Of Each Other Than Men Are, Study Finds

From Telegraph:

Women are less tolerant of each other than men are, according to a new study which may explain why some women prefer to have a male boss.

The research, published in the US journal Psychological Science, found that women formed a negative view of their peers much quicker than men did.

The team from Emmanuel College in Boston asked male and female college students to rate their room-mates under different scenarios.

When asked to judge how they would rate their room-mates if they carried out a single fictional act of negative behaviour, after they had been otherwise completely trustworthy, women were far more likely to be critical of them.

Men, on the other hand, were much more tolerant.

Empathy Partly Based On Genes, Mouse Study Shows

New research demonstrates that a highly social strain of mice can learn to associate a sound played in a specific cage with something negative simply by hearing a mouse in that cage respond with squeaks of distress. (Credit: iStockphoto/Brandon Laufenberg)

From Science Daily:

ScienceDaily (Feb. 16, 2009) — The ability to empathize with others is partially determined by genes, according to new research on mice from the University of Wisconsin-Madison and Oregon Health and Science University (OHSU).

In the study, a highly social strain of mice learned to associate a sound played in a specific cage with something negative simply by hearing a mouse in that cage respond with squeaks of distress. A genetically different mouse strain with fewer social tendencies did not learn any connection between the cues and the other mouse's distress, showing that the ability to identify and act on another's emotions may have a genetic basis.

Infectious Superbug Invades Beaches

From Live Science:

CHICAGO — Add the MRSA "superbug" to the list of concerns you bring to the beach nowadays, a research doctor said today.

It's still safe to go in the water, especially if you shower thoroughly before and after swimming, but antibiotic-resistant Staphylococcus aureus, a strain of bacteria that can cause staph infections that are difficult to treat with traditional anti-infection drugs such as methicillin, can be caught when you take a dip in ocean water, said Dr. Lisa Plano of the University of Miami's Miller School of Medicine.

MRSA stands for methicillin-resistant Staphylococcus aureus, or multiple-resistant Staphylococcus aureus. It has become a deadly and growing problem in hospitals in recent years.

"Catastrophic" Space Crash Spews Debris -- CBS News

Space Junk Generated From Satellite Collision Could Threaten Other Satellites For 10,000 Years, Experts Say

(CBS/AP) The crash of two satellites has generated an estimated tens of thousands of pieces of space junk that could circle Earth and threaten other satellites for the next 10,000 years, space experts said Friday.

One called the collision "a catastrophic event" that he hoped would force the new U.S. administration to address the issue of debris in space.

Russian Mission Control chief Vladimir Solovyov said Tuesday's smashup of a derelict Russian military satellite and a working U.S. Iridium commercial satellite occurred in the busiest part of near-Earth space - some 500 miles (800 kilometers) above Earth.

Our Eyes Constantly Flicker To Stop Us Going Blind, Experts Discover

Scientists believe flickering eye movements 'refresh' images on the retina

From The Daily Mail:

Unconscious flickering eye movements once thought to be random 'motor noise' may in fact be necessary to stop us going blind, a study has shown.

The imperceptible jumps and jiggles known as 'microsaccades' mean that a really steady stare is impossible.

Even when trying to fix a gaze on a stationary target, the eyes are always moving.

Experts have long dismissed these movements as the accidental result of spurious nerve signals. But new research shows they are actively controlled by the same brain region used to scan newspaper columns or track a moving object.

Scientists now think microsaccades provide a vital function by 'refreshing' images on the retina which would otherwise fade away.

From FOX News:

There's a new "holy grail" for hackers — President Obama's super-secure BlackBerry.

Despite warnings from his advisers, the president insisted on keeping his beloved PDA, which now has specially designed superencrypting security software.

But that just makes cracking into it more challenging — and, yes, it can be done, says the world's most famous hacker.

"It's a long shot, but it's possible," Kevin Mitnick told FOXNews.com. "You'd probably need to be pretty sophisticated, but there's people out there who are."

Doomed: Why Wikipedia Will Fail

From Ars Technica:

A cyberlaw professor argues that Wikipedia is doomed. The online encyclopedia will need to choose between being "high quality" and "open," but both choices are fraught with risk.

Law professor Eric Goldman loves Wikipedia, but he's also convinced that the site contains the "seeds of its own destruction." In other words, not to put too fine a point upon it, Wikipedia will fail.

Goldman made his provocative point at the Silicon Flatirons conference this weekend in Boulder, Colorado, standing at a heavy wooden podium in a multiuse room that had been donated to the University of Colorado by a graduating class back in the 1960s. Those students could not have foreseen Wikipedia at the time, but by 2008, everyone gathered in that room—from corporate vice presidents to think tank bosses to academics—had made use of the collaborative online encyclopedia.

The Secret of Successful Kissing

Droolly Smooches! : RebeccaJBuckley (CC Licensed)

From PopSci:

It's in the drool, fool.

Can drooling make you a better kisser? Scientific evidence suggests that wet, sloppy smooches pack a bigger biochemical punch than dry kisses and thus may be more likely to lead to sex and reproduction, says Rutgers University researcher Helen Fischer, who spoke today at the AAAS conference in Chicago.

Men are particularly prone to sloppy kissing, she notes, possibly because males tend to have a poor sense of smell and taste and aggressive face sucking may be an unconscious effort to gauge a partner's estrogen levels and fertility cycle. It may also be an unwitting effort to transmit testosterone, which can be found in saliva and can increase sexual attraction. Alternatively, it may also be just plain gross. (That would be my unscientific conclusion.)

Galaxy Has 'Billions Of Earths'

From The BBC:

There could be one hundred billion Earth-like planets in our galaxy, a US conference has heard.

Dr Alan Boss of the Carnegie Institution of Science said many of these worlds could be inhabited by simple lifeforms.

He was speaking at the annual meeting of the American Association for the Advancement of Science in Chicago.

So far, telescopes have been able to detect just over 300 planets outside our Solar System.

Very few of these would be capable of supporting life, however. Most are gas giants like our Jupiter; and many orbit so close to their parent stars that any microbes would have to survive roasting temperatures.

But, based on the limited numbers of planets found so far, Dr Boss has estimated that each Sun-like star has on average one "Earth-like" planet.

From The Daily Galaxy:

The study of the human brain is one of the most fascinating, and incredibly meta, subjects in existence. The almost Escherian experiments of one brain studying another brain (which is thinking about being studied by the first) have up to now been held back by one thing: the brain's owner is kind of using it so you can't poke too hard. Now a new scanning technique has allowed scientists to probe deeper than ever into the secrets of the mind.

Study Takes Step Toward Erasing Bad Memories

Image from The Daily Galaxy:

From Zimbio:

LONDON, Feb 15 (Reuters) - A widely available blood pressure pill could one day help people erase bad memories, perhaps treating some anxiety disorders and phobias, according to a Dutch study published on Sunday.

The generic beta-blocker propranolol significantly weakened people's fearful memories of spiders among a group of healthy volunteers who took it, said Merel Kindt, a psychologist at the University of Amsterdam, who led the study.

"We could show that the fear response went away, which suggests the memory was weakened," Kindt said in a telephone interview.
