Pills

For those of you who are not big on flavor, there is always food in pill form. While a common detail in movies and books about the future, the ‘meal in a pill’ is actually already here, though probably not as you imagined it.

Researchers in the UK have developed a pill that provides the health benefits of eating a Mediterranean diet. According to the developers, each pill has the vitamins and minerals that you would get from eating six and a half pounds of tomatoes.

Memory-Erasing Drugs Worries Are Overblown, Some Ethicists Say

Memory-erasing drugs could do more than erase a bad memory; they could help treat mental ailments such as post-traumatic stress disorder (PTSD), and one neuroethicist argues that these drugs should be developed and used, regardless of ethical concerns.

Though a magic bullet, erase-any-or-all-memory drug has yet to hit the market and is still decades away, scientists have made great strides in that direction, with one human trial under way for a drug called propranolol that can dampen post-traumatic-stress related negative memories. Other newly discovered brain pathways can be manipulated to ratchet memory up and down.

Solution for World's Water Woes

"Iceberg, dead ahead!"

The cry that heralded the Titanic's doom may now signal hope for thirsty people around the world, if glaciologists and engineers can somehow harness flotillas of icebergs at the frozen corners of the Earth. Such a dream took a step forward recently when a French team simulated how to tow an iceberg from the Arctic to countries that need fresh drinking water.

Ambitions for making icebergs into the world's drinking fountains began with Saudi Prince Mohammed al Faisal in the 1970s. Al Faisal, nephew of Saudi Arabia's King Khalid, teamed up with French engineer Georges Mougin to create an ill-fated company based on tapping iceberg water. Since 2003, Mougin has resurrected the idea with the help of computer modeling from the French company Dassault Systemes.

X-Ray Microscope Enables Nanovision

Forget X-ray glasses. A new X-ray microscope can see details a small as a billionth of a meter — without even using a lens.

Instead, the new microscope uses a powerful computer program to convert patterns from X-rays bouncing off materials into images of objects as small as a one nanometer across, on the scale of a few atoms.

Unlike Superman's X-ray vision, which allows him to look through walls to see the bad guys beyond, the new technology could be used to look at different elements inside a material, or to image viruses, cells and tissue in great detail, said study researcher Oleg Shpyrko, a physicist at the University of California, San Diego. But one of the most important applications is in nano-sized engineering, Shpyrko said.

8 Reasons Our Waistlines Are Expanding

In 1998, 29 million people suddenly became overweight without gaining an ounce. That summer, the U.S. government announced new guidelines lowering the threshold of what classifies a person as overweight. Previously, if your body mass index (BMI) was less than 28 for men, or 27 for women, you were considered "normal." Now only BMIs of 25 or below are considered healthy. (BMI is a ratio of weight to height, and is considered an indicator of how much body fat a person has.)

9 Good Sources of Disease-Fighter Vitamin D

Sunlight: A whopping 80 percent or more of the vitamin D we need could come from the sun — if we let it. Sunscreen blocks about 97 percent of our body's vitamin D production, according to Dr. Mark Hyman, founder and medical director of the UltraWellness Center in Lenox, Mass. But we needn't endanger ourselves to take advantage of the sun's benefits: Fair-skinned people need less than 30 minutes of casual exposure on bright days to meet their daily requirement, while darker-skinned individuals need about two hours, Hyman said.

Ways to Eat More Fruits and Vegetables

The new food plate unveiled by the Department of Agriculture today (June 2) sends a clear message: eat more fruits and vegetables. Chances are, you've heard this message before. And chances are, you're guilty of not heeding it. But meeting the daily requirement for fruits and vegetables need not be such a struggle.

Here are six easy ways to get more of these important foods into your diet, according to Heather Mangieri, a nutrition consultant and spokeswoman for the American Dietetic Association.

How to Stick to an Exercise Routine

Many people struggle to adhere to an exercise routine. Researchers are beginning to unravel what makes us more likely to stick to a workout regime and what strategies we can employ to boost our willpower.

A key is having the confidence that you can do it, a new study shows. The researchers call this type of focused confidence "self-efficacy."

"You can apply the concept of self-efficacy to every single health behavior you can think of, because in many ways that really is what gets us through the day, gets us through the tough times," said Edward McAuley, a University of Illinois kinesiology and community health professor who led the research. "People who are more efficacious tend to approach more challenging tasks, work harder and stick with it even in the face of early failures."

Human Body Might Adapt to Radiation Exposure

Doctors who are regularly exposed to X-ray radiation may undergo changes in their cells that protect them from the radiation they encounter, a new study suggests.

These physicians have higher levels of a particular antioxidant called glutathione inside their red blood cells than physicians who don't use X-rays regularly, the study showed. In addition, some of these cells may be better able to self-destruct, which would be protective if they turned cancerous.

However, it's still not clear whether these changes will be beneficial in the long run, or reduce the physicians' cancer risk, said study researcher Dr. Gian Luigi Russo, a senior research scientist at the National Research Council (CNR) in Pisa, Italy. Instead, these alterations might be early indicators of a disease, Russo said.

Fighting Aging? Skip the Botox and Go for the Face Cream

People might like you more if you don't have surgery or get injections to look younger, a new study suggests.

The results show that study participants felt more warmth toward a woman, and said she was less vain, if they were told she fought the signs of aging by staying out of the sun or using face cream than if they were told she had used the cosmetic drug Botox or had a face-lift.

"This is important because it shows that despite the emphasis on looking younger in society, there are possible negative social consequences to fighting the signs of aging," using more extreme methods, said study researcher Alison Chasteen, a psychology professor at the University of Toronto.

D for Vitamin D

First of all, vitamin D is very important for bone health. Vitamin D enhances calcium absorption. Together they keep bones strong and prevent breakdown of bone. Vitamin D decreases our risk for osteoporosis. Low blood values of vitamin D have been associated with hip fractures, vertebral fractures, and wrist fractures. With adequate calcium and vitamin D in all ages of people, bone loss would be prevented as well as tooth loss.

Silent Sound Technology- The Future of Communication

Silent Sound Technology

Have you ever found yourself in a situation where, no matter how much you blare on the phone, the receiver at the other end can never hear you. It may be a busy street, a crowded bus or even a late night party at the pub, the biggest issue while talking over the phone is one just can’t be loud enough. So does that mean you stop receiving any calls in a crowded place? (Image taken from http://wn.com)

Antimatter

Like Superman's alter-ego, Bizzaro, the particles making up normal matter also have opposite versions of themselves. An electron has a negative charge, for example, but its antimatter equivalent, the positron, is positive. Matter and antimatter annihilate each other when they collide and their mass is converted into pure energy by Einstein's equation E=mc2. Some futuristic spacecraft designs incorporate anti-matter engines.

Huge 'Ocean' Discovered

Scientists scanning the deep interior of Earth have found evidence of a vast water reservoir beneath eastern Asia that is at least the volume of the Arctic Ocean.

The discovery marks the first time such a large body of water has found in the planet’s deep mantle.

The finding, made by Michael Wysession, a seismologist at Washington University in St. Louis, and his former graduate student Jesse Lawrence, now at the University of California, San Diego, will be detailed in a forthcoming monograph to be published by the American Geophysical Union.

Gravity

It's all in your head

Gravity may be pretty consistent on Earth, but our perception of it isn't. According to research published in April 2011 in the journal PLoS ONE, people are better at judging how objects fall when they're sitting upright versus lying on their sides.

The finding means that our perception of gravity may be less based on visual cues of gravity's real direction and more rooted in the orientation of the body. The findings may lead to new strategies to help astronauts deal with microgravity in space.
