A noninvasive technology can accurately detect even low levels of malaria infection through the skin in seconds with a laser scanner that requires no dyes, diagnostic chemicals, or needles.
As reported in a preclinical study published this week in the Proceedings of the National Academy of Sciencesthe technology detected a single malaria-infected cell among a million normal cells with zero false-positive readings.
The technology uses a low-powered laser that creates tiny vapor “nanobubbles” inside malaria-infected cells. The bursting bubbles have a unique acoustic signature that allows for an extremely sensitive diagnosis

Super Short, Intense Workouts Won't Help You Lose Weight

Super short workouts sound fantastic. Who wouldn't want to pack 60 minutes worth of exercise into 20—or sometimes even less? We've discussed quite a few, but not a lot about what you can expect while doing them. Amby Burfoot, writing for Runner's World, decided to take a look at the numbers.

Why We Are So Materialistic Even If It Doesn't Make Us Happy

No matter who you are, it's easy to get a little caught up in the idea of getting new stuff. Here's a look at why your brain is so materialistic and what you can do to keep it from overwhelming you.

Smart Glasses Reveal What It's Like to Have Superpowers

Atheer's video suggested the potential in a future of wearable technology and 3D smart glasses. Watch it above; we dare you not to get excited.
"The experiences shown in the video from the user’s point of view can be available in 1-2 years," Atheer CEO Soulaiman Itani told Mashable. "Every functionality shown has been prototyped in a minimalistic way, but more with the core technology. Minimizing the hardware to be as small as in the video will probably take closer to eight years."

Numerous scientific studies have concluded that two common bacteria that cause colds, ear infections, strep throat, and more serious infections cannot live for long outside the human body. So conventional wisdom has long held that these bacteria won’t linger on inanimate objects like furniture, dishes, or toys.
But new research in Infection and Immunity shows that Streptococcus pneumoniae andStreptococcus pyogenes do persist on surfaces for far longer than has been appreciated. The findings suggest that additional precautions may be necessary to prevent infections, especially in settings such as schools, daycare centers, and hospital.

For Fitness, Intensity Matters

This year, exercise science expanded and fine-tuned our understanding of how physical activity affects our brainsjoints,hearts, and even genes, beginning before birth and continuing throughout our lifespans, which can be lengthened, it seems, by exercise, especially if we pick up the pace.
But the lesson that seemed to emerge most persistently from the fitness-related studies published this year was that intensity matters, especially if you wish to complete your workout quickly. The most popular column that I wrote this year, by a wide margin, detailed “The Scientific 7-Minute Workout,” a concept that appealed, I have no doubt, because the time commitment was so slight. But the vigor required was considerable; to gain health benefits from those seven minutes, you needed to maintain a thumping heart rate and spray sweat droplets around the room.
Almost halving the time spent exercising was also effective, a later and likewise popular column showed. In that study, out-of-shape volunteers who ran on a treadmill for a mere four minutes three times a week for 10 weeks raised their maximal oxygen uptake, or endurance capacity, by about 10 percent and significantly improved their blood sugar control and blood pressure profiles.

Here's Why You Should Stop Setting Goals

And for most of us, the path to those things starts by setting a specific and actionable goal. At least, this is how I approached my life until recently. I would set goals for classes I took, for weights that I wanted to lift in the gym, and for clients I wanted in my business.
What I’m starting to realize, however, is that when it comes to actually getting things done and making progress in the areas that are important to you, there is a much better way to do things.
It all comes down to the difference between goals and systems.
Let me explain.

Sweeping Photos Span an Entire Day in a Single Frame

Stephen Wilkes is the first to admit the huge photos in his Day to Night series take an absurd amount of time and effort to produce. And he knows you might wonder why he’d spend 15 hours shooting an image and weeks editing it. But in an era when anyone with a phone can snap a pic and edit it in less time than it takes to say “OMG,” his fanatical approach is his way of cutting through the visual noise and make an impression on people.
Wilkes says he is “maniacal” in his attention to detail when making these his information-dense, hyper-curated and highly polished accounts of a single day in some of the world’s most iconic locations. Every inch of his photos, some as big as 10 feet wide, are meant to tell a story. He says telling that story is an all-consuming process.

Raising Children With an Attitude of Gratitude

Research Finds Real Benefits for Kids Who Say 'Thank You'

Giving thanks is no longer just holiday fare. A field of research on gratitude in kids is emerging, and early findings indicate parents' instincts to elevate the topic are spot-on. Concrete benefits come to kids who literally count their blessings.
Gratitude works like a muscle. Take time to recognize good fortune, and feelings of appreciation can increase. Even more, those who are less grateful gain the most from a concerted effort. "Gratitude treatments are most effective in those least grateful," says Eastern Washington University psychology professor Philip Watkins.
The old adage that virtues are caught, not taught, applies here," says University of California, Davis psychology professor Robert Emmons. Parents need to model this behavior to build their children's gratitude muscle. "It's not what parents want to hear, but you cannot give your kids something that you yourselves do not have," Dr. Emmons says.
This may seems obvious, but it eludes many parents, Dr. Watkins says. "I think the most important thing for us adults to realize is we're not very grateful either," he says.
Another study examined 1,035 high-school students outside New York City. The study, published in 2010 in the Journal of Happiness Studies, found that those who showed high levels of gratitude, for instance thankfulness for the beauty of nature and strong appreciation of other people, reported having stronger GPAs, less depression and envy and a more positive outlook than less grateful teens.
Further, teens who strongly connected buying and owning things with success and happiness reported having lower GPAs, more depression and a more negative outlook. "Materialism had just the opposite effect as gratitude—almost like a mirror," says study co-author Jeffrey Froh, associate professor of psychology at Hofstra University.

Alabaman Becomes Ray of Hope to Desperate Family in India

BIRMINGHAM, Ala.—Real-estate developer Chip Moore left his four-bedroom home here one morning in his GMC Yukon SUV, drove through his community's gate, past the golf course to a Publix supermarket.
There, he wired $1,000 to Rahima Sheikh, a gravely ill woman in a 240-square-foot home in India. He considered it a one-time thing.
"I thought I'd sling some money at the problem," he says, "and make it go away."
Instead, 10 months later, Mr. Moore was in northern India, sitting cross-legged on the roof of Mrs. Sheikh's tiny brick house on an August night, eating goat curry and talking with her husband about the business Mr. Moore had helped the family start as a way to escape poverty.
The Sheikhs' struggle is common in India, where two-thirds live below the international poverty level of $2 a day. Medical-care costs and other unforeseen expenses can plunge a family into destitution. The Sheikhs and most people in their district lack toilets and don't have electricity much of the day.
One family's helping another directly is "not a suitable model" to fight global poverty, says Cambridge University's Mr. Munshi. But, he says, Mr. Moore's and Mr. Srivastava's efforts will probably help the Sheikhs because the two avoided the pitfalls of many development efforts by tailoring their assistance to the situation. "One thing that never works is trying to provide generalizable solutions to all the problems that people face."
The Sheikhs' business has been thriving the past few months, with more orders than they can meet. Still, they were back with another request in November, for $3,000 to buy an adjacent lot to build a bathroom. Mr. Moore declined, saying he wanted them focused on their business and on curing Mrs. Sheikh. She used $180 in tailoring profits and borrowed $500 from a friend to buy a sliver of the land, anyway. "I hate that they borrowed," Mr. Moore says.

Outbreak! Watch How Quickly An Epidemic Would Spread Across The World

In March of 2009, the Mexican government confirmed it: A four-year-old boy in eastern Mexico’s La Gloria village had swine flu, or H1N1. Sixty percent of the village had reported an unknown respiratory illness back in February, and since, it looked like the virus had jumped. A flu case later confirmed to be H1N1 popped up in California. Then, it spanned an ocean. By late April, H1N1 had been reported in Spain, Israel, New Zealand, Austria, Germany, the United Kingdom, and Switzerland.
Within an increasingly globalized and mobile world, the spread of contagion doesn’t work how it used to. But by taking these factors into account, theoretical physicist Dirk Brockmann and his colleagues have a radical new model that could predict the arrival times of the next global pandemic. The model relies on something called “effective distance,” and it destroys a centuries-old way of thinking about maps

Wireless Speakers Let Music Roam Free

The simplicity and reduced size of many of the new wireless speakers make sense to me. They are easy to move physically and boss around mechanically, usually with simple controls on a smartphone. I like the idea of shifting my speakers to another place or banishing them from my sight, when I want to. With wireless speakers, especially smaller ones, this is reasonable.
Multiroom wireless systems, with speakers placed in as many rooms as you like, bring on different concerns. Until recently, I saw only three uses for them. One was to become a crisper family autocrat. (We will now all, in different rooms, listen to my No. 1 record of the year.) Another was to help with hearing podcasts, so you don’t forget where you are in someone’s run-on sentence while you move from the living room to the kitchen. And the third was to help you imagine that you live in a department store, where your ambulatory shopping experience is made more elegant by an unbroken soundtrack.
But my family and I just moved, and I’ve been rethinking the audio question down to the root. Maybe there’s more to it than I thought.
My rethinking really started when I got my hands on the wireless Sonos speakers. The company’s speakers have been justifiably popular since 2009, when it introduced what is now called the Play:5 speaker: $400 and roughly 8 inches by 14 inches, a rectangle that sits on its long end.

Are Nuts a Weight-Loss Aid?

The reports about their many benefitshave come thick and fast: studies finding that people who eat nuts (tree nuts like cashews, almonds and pistachios, along with their legume pal, the peanut) live longer and healthier lives, with less risk of chronic ailments like heart disease, respiratory problems and Type 2 diabetes.
But perhaps the most startling news is that nuts may help in maintaining a healthy weight. Research has found that people can snack on modest amounts of them without gaining pounds, and that nuts can even help in slimming down.
Why do nuts appease the appetite so well? Dr. Mattes pointed to several studies.
“They’re high in protein, and protein is satiating,” he said. “They’re high in fiber, and fiber is satiating. They’re rich in unsaturated fats, and there is some literature that suggests that has satiety value. They’re crunchy, and that would suggest just the mechanical aspect of chewing generates a satiety signal.”
Snacking on nuts makes it likely that you will eat less later in the same day, according to some research. That decrease in consumption can make up for many of the nuts’ calories — as much as three-fourths of them, studies have shown.
Nuts are also resistant to digestion, thanks to the tough walls of their cells. As much as one-fifth of the fat in nuts never gets absorbed by the body, Dr. Mattes estimated in a 2008 paper published by The Journal of Nutrition. He noted some weaker evidence that nuts may cause people to burn a little more energy as they simply sit around.
Even the fat that the body absorbs from nuts tends to be virtuous. It’s mostly unsaturated fat, with lesser amounts of the saturated type whose excessive consumption has been associated with heart disease.

How you sense a smell—as pleasant or offensive—may be decided by a difference at the smallest level of DNA—one amino acid on one gene, researchers say.
There are about 400 genes coding for the receptors in our noses, and according to the 1000 Genomes Project, there are more than 900,000 variations of those genes. These receptors control the sensors that determine how we smell odors. A given odor will activate a suite of receptors in the nose, creating a specific signal for the brain.
But the receptors don’t work the same for all of us, says Hiroaki Matsunami, associate professor of molecular genetics and microbiology at the Duke University School of Medicine. In fact, when comparing the receptors in any two people, they should be about 30 percent different.
While researchers had earlier identified the genes that encode for odor receptors, it has been a mystery how the receptors are activated. To determine what turns the receptors on, researchers cloned more than 500 receptors each from 20 people that had slight variations of only one or two amino acids and systematically exposed them to odor molecules that might excite the receptors.
By exposing each receptor to a very small concentration—1, 10, or 100 micromoles—of 73 odorants, such as vanillin or guaiacol, the group was able to identify 27 receptors that had a significant response to at least one odorant.

For tens of millions of Americans, there’s no such thing as the sound of silence. Instead, even in a quiet room, they hear a constant ringing, buzzing, hissing, humming, or other noise in their ears that isn’t real.
Tinnitus, or ringing in the ears, may be the result of sensory nerves in the face and neck trying to compensate for a reduction of input from the ear’s cochlea, new research shows.
The findings by University of Michigan Medical School researchers offer a new target for treating the condition. The team has a patent pending and device in development based on the approach.
Susan Shore, the senior author of the paper, explains that her team has confirmed that a process called stimulus-timing dependent multisensory plasticity is altered in animals with tinnitus—and that this plasticity is “exquisitely sensitive” to the timing of signals coming in to a key area of the brain. The findings are published online in the Journal of Neuroscience.

Chowing Down On Meat, Dairy Alters Gut Bacteria A Lot, And Quickly

Looks like Harvard University scientists have given us another reason to walk past the cheese platter at holiday parties and reach for the carrot sticks instead: Your gut bacteria will thank you.
Switching to a diet packed with meat and cheese — and very few carbohydrates — alters the trillions of microbes living in the gut, scientists report Wednesday in the journal Nature.
The change happens quickly. Within two days, the types of microbes thriving in the gut shuffle around. And there are signs that some of these shifts might not be so good for your gut: One type of bacterium that flourishes under the meat-rich diet has been linked to inflammation and intestinal diseases in mice.
"I mean, I love meat," says microbiologist Lawrence David, who contributed to the study and is now at Duke University.
"But I will say that I definitely feel a lot more guilty ordering a hamburger ... since doing this work," he says.

The Best Fitness Tracker

Every fitness tracker currently available has its shortcomings, but the $130 Fitbit Force’s flaws are easy to forgive given the convenience of its wrist-mounted design and legible screen that tracks your stats in real time. It is the only fitness tracker that combines all those features with the added accuracy of an altimeter. The fact that it’s a part of the most comprehensive fitness ecosystem around is gravy. Unfortunately, the wrist strap can be a bit tricky to latch and it’s not as water-resistant as other options, but it’s still the one we’d get.

Global Study Finds Majority Believe Traditional Hospitals Will Be Obsolete In The Near Future

A global study was released this morning by the Intel Corporationindicating that around the world people’s health care wants and needs are principally focused on technology and personalization. The “Intel Health Innovation Barometer” found a consistent theme: customized care. At the intersection of health, care and technology, communities around the world consistently said they wanted to see their biological makeup and individual behaviors used to make receiving care more effective and efficient. This unsurprisingly was described by people through means such as telehealth, mobile health and the sharing of health information in real time. However, surprising methods of care were also common themes throughout the world such as ingestible monitoring systems and care that involves no utilization of hospitals.
Surprising Findings:
-       Traditional hospitals, according to 57% of people, will be obsolete in the future
-       Majority of people (84%) would be willing to share their personal health information to advance and lower costs in the health care system
-       More than 70% of people are receptive to using toilet sensors, prescription bottle sensors and swallowed health monitors
-       72% of those surveyed would be willing to see a doctor via video conference for non-urgent appointments
-       66% of people say they would prefer a care regimen that is designed specifically for them based on their genetic profile or biology
-       More than half of people (53%) would trust a test they personally administered as much or more than if that same test was performed by a doctor
-       About 30% of people would trust themselves to perform their own ultrasound

In Food Cravings, Sugar Trumps Fat

What makes a milkshake so irresistible?
Is it the sweet flavor that our taste buds are after? Or the smooth and creamy texture? Or perhaps it is the copious blend of fat and sugar?
An intriguing new study suggests that what really draws people to such treats, and prompts them to eat much more than perhaps they know they should, is not the fat that they contain, but primarily the sugar

Exercise as Potent Medicine

Exercise can be as effective as many frequently prescribed drugs in treating some of the leading causes of death, according to a new report. The study raises important questions about whether our health care system focuses too much on medications and too little on activity to combat physical ailments.
For the study, which was published in October in BMJ, researchers compared how well various drugs and exercise succeed in reducing deaths among people who have been diagnosed with several common and serious conditions, including heart disease and diabetes.

Differences in How Men and Women Think Are Hard-Wired

So many things come down to connections—especially the ones in your brain.
Women and men display distinctive differences in how nerve fibers connect various regions of their brains, according to a half-dozen recent studies that highlight gender variation in the brain's wiring diagram. There are trillions of these critical connections, and they are shaped by the interplay of heredity, experience and biochemistry.
No one knows how gender variations in brain wiring might translate into thought and behavior—whether they might influence the way men and women generally perceive reality, process information, form judgments and behave socially—but they are sparking controversy.
Dr. Verma's maps of neural circuitry document the brain at moments when it is in a fury of creation. Starting in infancy, the brain normally produces neurons at a rate of half a million a minute, and reaches out to make connections two million times a second. By age 5, brain size on average has grown to about 90% of adult size. By age 20, the average brain is packed with about 109,000 miles of white matter tissue fibers, according to a 2003 Danish study reported in the Journal of Comparative Neurology.
Spurred by the effects of diet, experience and biochemistry, neurons and synapses are ruthlessly pruned, starting in childhood. The winnowing continues in fits and starts throughout adolescence, then picks up again in middle age. "In childhood, we did not see much difference" between male and female, Dr. Verma said. "Most of the changes we see start happening in adolescence. That is when most of the male-female differences come about."

Can an App Improve Vision?

The Ache: In presbyopia, the eye's lens loses elasticity with age. The ability to focus on near objects deteriorates, resulting in the need for reading glasses.
The Claim: A 12-week, scientifically tested training program, newly available as an iPhoneapp, uses a technique called perceptual learning to reduce—or even eliminate—the need for reading glasses.
The Verdict: A 30-person study published in February 2012 in the journal Scientific Reports found that after trying the program—now on sale as an iPhone app calledGlassesOff GLSO -4.62% —participants on average could read letters 1.6 times smaller than they could previously. The program is much more likely to show improvement in adults 40 to 60 years old, scientists say.

5 Health Tech Trends to Watch in 2014

2013 was a big year for consumer health technology. According to mobile tech consultancy Research2Guidance, there are now close to 100,000 mobile health apps in 62 app stores, with the top 10 apps generating over 4 million free downloads every day.
This year also saw increased adoption of wearable tech, such as the Nike+ FuelBand and Fitbit — a market that is expected to grow to 100 million units by the end of 2014.
So if 2013 was the year of wearables and health apps, what’s on tap for next year? Here are five exciting health tech trends to keep an eye on for the new year.

What Does the Spleen Do?

Snacking Your Way to Better Health

The more often nuts were consumed, the less likely participants were to die of cancer, heart disease and respiratory disease, and not because nut eaters succumbed to other diseases. Their death rate from any cause was lower during the years they were followed. (The nuts in question were pistachios, almonds, Brazil nuts, cashews, hazelnuts, macadamias, pecans, pine nuts, peanuts and walnuts.)
Those who ate nuts seven or more times a week were 20 percent less likely to die from 1980 to 2010; even among those who consumed nuts less often than once a week, the death rate was 11 percent lower than for those who did not eat them.
I know what you’re thinking: Aren’t nuts fattening? Yes, an ounce of nuts has 160 to 200 calories, nearly 80 percent from fat.
But in study after study, the more often people ate nuts, the leaner they tended to be.

Wasps and honeybees can remember individual faces

This blog is amazing for all who are fascinated by science... and this is an example of an article from it....

When these insects view an individual (be it another insect or the person who just pissed them off by swinging a newspaper at them), their field of vision is broken up into hexagons from the thousands of ommatidia that make up the compound eye. Essentially, they process information based on these chunks from the structures in the eye that act as individual units and put the entire picture together. It might not be very clear compared to what we are used to since they don't have a pupil to regulate the amount of light coming in onto the retina, but it is good enough to allow wasps and bees to discern prominent facial features that can be used for identification. -

Malcolm Gladwell on the Advantages of Disadvantages

In his new bestseller, David and Goliath: Underdogs, Misfits, and the Art of Battling Giants, Malcolm Gladwell looks at what happens when ordinary people confront powerful opponents. He starts the book by dissecting the classic tale of David and Goliath, challenging our beliefs about what the story tells us regarding underdogs and giants, and ultimately, our fundamental assumptions about power.
Wharton management professor Adam M. Grant recently interviewed Gladwell about his new book when he visited campus as a guest lecturer in the Authors@Wharton series. Gladwell shared why he never roots for the underdog, where he comes up with the ideas for his books and sets the record straight on the biggest misunderstandings about his work.
An edited transcript of the conversation follows.
