Antimicrobial Copper Could Save Thousands Of Lives And Billions Of Dollars

In less than two hours this material can kill 99.9% of most of the bacteria on its surface, including E.coli, influenza, staphylococcus and H1N1.

A recent four-year trial has shown that using it on such frequently touched hospital items as bed rails, IV poles, tray tables and nurse call buttons reduces infection rates by more than 40%.

With hospital-acquired infections (HAIs) the fourth-leading cause of death in the United States, such a wonder material could have a profound impact on the health care industry.

The Holographic Universe: Is Our 3D World Just an Illusion?

Drawing upon the Holographic Principle, the premise behind the Fermilab project is that space is two dimensional, and that the third dimension is inextricably linked with time. If that's the case, our 3D world is merely an approximate illusion. Assuming that's true, the illusion is likely imperfect and blurry, just as photographs and videos are, especially when viewed on a granular level.

It's difficult enough for most humans to grasp the idea that our planet is just one of countless others in our galaxy -- and a pretty small one, at that.

Then, of course, there's the concept that our galaxy is just one of billions of others in the universe -- sure to compound any confusion considerably.

It seems safe to say, however, that neither of those notions can compete on the mind-bending scale, so to speak, with an idea that's currently being investigated at the U.S. Department of Energy's Fermilab.

Ready for a hurting brain? Here goes: Fermilab is working on a device to test the theory that our whole universe is simply a hologram.

You are what you tweet: Tracking public health trends with Twitter

Twitter allows millions of social media fans to comment in 140 characters or less on just about anything: an actor's outlandish behavior, an earthquake's tragic toll or the great taste of a grilled cheese sandwich.

But by sifting through this busy flood of banter, is it possible to also track important public health trends? Two Johns Hopkins University computer scientists would respond with a one-word tweet: "Yes!"

Mark Dredze and Michael J. Paul fed 2 billion public tweets posted between May 2009 and October 2010 into computers, then used software to filter out the 1.5 million messages that referred to health matters. Identities of the tweeters were not collected by Dredze, a researcher at the university's Human Language Technology Center of Excellence and an assistant research professor of computer science, and Paul, a doctoral student.

The bare-faced truth about big fat liars

Men with wide faces are more likely to lie and cheat than narrow-faced men but they seem to make better businessmen, according to a study that links facial features with a tendency to engage in unethical behaviour.

Scientists believe they have evidence to show that the width of a man's face relative to his facial height is an indicator of how powerful he feels and of his willingness to surreptitiously break social rules to achieve his goals.

The findings suggest that the width-to-height ratio of the face could be an ancient evolutionary signal of a man's aggressiveness when dealing with competitors, said Professor Michael Haselhuhn of the University of Wisconsin-Milwaukee, who led the study.

Lifeforms Can Clean Up Radiation ... Naturally

When BP spilled huge quantities of oil into the Gulf, the company and the government ignored natural ways to help clean up the mess, and instead dumped toxic dispersants into the Gulf which actually made things worse.

Likewise - believe it or not - there may be natural ways to help clean up radiation from Fukushima and elsewhere, and to reduce human and animal exposure to radioactive elements.

Tree frogs' self-cleaning feet could solve a sticky problem

Tree frogs have specially adapted self-cleaning feet which could have practical applications for the medical industry.

"Tree frog feet may provide a design for self-cleaning sticky surfaces, which could be useful for a wide range of products especially in contaminating environments -- medical bandages, tyre performance, and even long lasting adhesives," says researcher, Niall Crawford at the University of Glasgow who will be presenting this work at the Society for Experimental Biology Annual Conference in Glasgow on 3rd of July, 2011.

Why Our Monkey Brains Are Prone to Procrastination (No, It's Not Just Laziness or Lack Of Willpower)

The Misconception: You procrastinate because you are lazy and can’t manage your time well.


The Truth: Procrastination is fueled by weakness in the face of impulse and a failure to think about thinking.

Is there a link between obesity, chronic illness and bullying?

Children who are overweight or obese are more likely to be victimised by bullying when compared to children who are not overweight.

The findings, to be presented July 6 at the Annual Scientific Meeting of the Society for Academic Primary Care held at the University of Bristol, explore the prevalence of overweight and obesity in nine-year-olds and its associations with chronic illness and bullying.

Functioning small intestine created in laboratory experiments

Researchers at The Saban Research Institute of Children's Hospital Los Angeles have successfully created a tissue-engineered small intestine in mice that replicates the intestinal structures of natural intestine -- a necessary first step toward someday applying this regenerative medicine technique to humans.

The study led by Tracy C. Grikscheit, MD -- "A Multicellular Approach Forms a Significant Amount of Tissue-Engineered Small Intestine in the Mouse" -- has been published in the July issue of Tissue Engineering Part A, a biomedical journal.

Surprising culprits behind cell death from fat and sugar overload

Excess nutrients, such as fat and sugar, don't just pack on the pounds but can push some cells in the body over the brink. Unable to tolerate this "toxic" environment, these cells commit suicide.

Now, scientists at Washington University School of Medicine in St. Louis have discovered three unexpected players that help a cell overloaded with fat initiate its own demise. They have shown that these molecules leading a cell to self-destruct are not proteins as might be expected, but small strands of RNA, a close chemical cousin to DNA. Since these small nucleolar RNAs play well-known roles in building proteins, the researchers were surprised to implicate them in killing cells.

New technology makes textiles permanently germ-free

A University of Georgia researcher has invented a new technology that can inexpensively render medical linens and clothing, face masks, paper towels -- and yes, even diapers, intimate apparel and athletic wear, including smelly socks -- permanently germ-free.

The simple and inexpensive anti-microbial technology works on natural and synthetic materials. The technology can be applied during the manufacturing process or at home, and it doesn't come out in the wash. Unlike other anti-microbial technologies, repeated applications are unnecessary to maintain effectiveness.

In Eyes, a Clock Calibrated by Wavelengths of Light

Just as the ear has two purposes — hearing and telling you which way is up — so does the eye. It receives the input necessary for vision, but the retina also houses a network of sensors that detect the rise and fall of daylight. With light, the body sets its internal clock to a 24-hour cycle regulating an estimated 10 percent of our genes.

Air pollution linked to learning and memory problems, depression

Long-term exposure to air pollution can lead to physical changes in the brain, as well as learning and memory problems and even depression, new research in mice suggests.

While other studies have shown the damaging effects of polluted air on the heart and lungs, this is one of the first long-term studies to show the negative impact on the brain, said Laura Fonken, lead author of the study and a doctoral student in neuroscience at Ohio State University.

"The results suggest prolonged exposure to polluted air can have visible, negative effects on the brain, which can lead to a variety of health problems," Fonken said.

Rose-colored beer goggles: Some drinkers believe social benefits of heavy drinking outweigh harms

A study by University of Washington psychologists shows some people continue to drink heavily because of perceived positive effects, despite experiencing negative effects such as hangovers, fights and regrettable sexual situations.

According to participants in the study, boosts of courage, chattiness and other social benefits of drinking outweigh its harms, which they generally did not consider as strong deterrents.

The findings offer a new direction for programs targeting binge drinking, which tend to limit their focus to avoiding alcohol's ill effects rather than considering its rewards.

The first person to reach 150 is already alive... and soon we'll live to be a THOUSAND, claims scientist

It's a milestone that few, if any, of us expect to reach.

But the first person who will live to see their 150th birthday has already been born, according to a leading scientist.

Even more incredibly, Aubrey De Grey believes that the first person to live for 1,000 years will be born in the next two decades.

AFP: Portugal drug law show results ten years on, experts say

Health experts in Portugal said Friday that Portugal's decision 10 years ago to decriminalise drug use and treat addicts rather than punishing them is an experiment that has worked.

"There is no doubt that the phenomenon of addiction is in decline in Portugal," said Joao Goulao, President of the Institute of Drugs and Drugs Addiction, a press conference to mark the 10th anniversary of the law.

The number of addicts considered "problematic" -- those who repeatedly use "hard" drugs and intravenous users -- had fallen by half since the early 1990s, when the figure was estimated at around 100,000 people, Goulao said.

Why you should love germs

It's understandable that parents want to keep their children's environments clean, especially when kids are young. Moms wash bottles in hot water, clean pacifiers that fall on the ground and take dirty things out of their kids' mouths.

But overall, when it comes to germs, most people have it backward: With relatively few exceptions, they are good for our kids.

Keeping things clean is smart, but going crazy using antibacterial hand soaps, buying antibacterial kids' toys and other products and overusing antibiotic medications is actually killing off the microbes that can help strengthen the immune system.

Mathematicians Want to Say Goodbye to Pi

"I know it will be called blasphemy by some, but I believe that pi is wrong."

That's the opening line of a watershed essay written in 2001 by mathematician Bob Palais of the University of Utah. In "Pi is Wrong!" Palais argued that, for thousands of years, humans have been focusing their attention and adulation on the wrong mathematical constant.

Two times pi, not pi itself, is the truly sacred number of the circle, Palais contended. We should be celebrating and symbolizing the value that is equal to approximately 6.28 — the ratio of a circle's circumference to its radius — and not to the 3.14'ish ratio of its circumference to its diameter (a largely irrelevant property in geometry).

Important step in next generation of computing: Vital insight into spintronics

Scientists have taken one step closer to the next generation of computers. Research from the Cavendish Laboratory, the University of Cambridge's Department of Physics, provides new insight into spintronics, which has been hailed as the successor to the transistor.

Spintronics, which exploits the electron's tiny magnetic moment, or 'spin', could radically change computing due to its potential of high-speed, high-density and low-power consumption. The new research sheds light on how to make 'spin' more efficient.

Who wants to live forever? Scientist sees aging cured

If Aubrey de Grey's predictions are right, the first person who will live to see their 150th birthday has already been born. And the first person to live for 1,000 years could be less than 20 years younger.

A biomedical gerontologist and chief scientist of a foundation dedicated to longevity research, de Grey reckons that within his own lifetime doctors could have all the tools they need to "cure" aging -- banishing diseases that come with it and extending life indefinitely.

"I'd say we have a 50/50 chance of bringing aging under what I'd call a decisive level of medical control within the next 25 years or so," de Grey said in an interview before delivering a lecture at Britain's Royal Institution academy of science.
