Would you still watch your favorite television program if you had to cycle for an hour before you could view it?

Couch potatoes will be horrified, but fresh advances in human-powered technology — where users power appliances through their own motion — could one day see a ‘workout-to-watch’ scenario become reality.

Human power is rapidly gaining in popularity worldwide as businesses seek ‘greener’ methods of operating. [ read more ]

From sensors in workout gear that monitor sweating while you run at the gym, to underwear that aims to detect cancer cells, the contents of our wardrobes have been quietly undergoing a revolution. Over the past decade, there has been a rise in the number of ways that technology is being incorporated into items of our clothing.

Trials of smart clothes that can repel insects and mask nasty odours such as cigarette smoke have proved successful and are already being marketed.

Compounds boost endurance and allow mice to run for substantially longer.

The elusive exercise pill just took a step closer to becoming a reality. Scientists have found that two compounds can boost endurance in mice by changing the metabolic properties of the animals’ muscle. One of the drugs appears to mimic some of the benefits of exercise even in sedentary mice. But the most dramatic benefit comes from combining one of the drugs with exercise, enabling mice to run 60 to 75 percent longer. [ read more ]

Jeff Lichtman hopes to elucidate brain development and disease with new technologies that illuminate the web of neural circuits.

Displayed on Jeff Lichtman’s computer screen in his office at Harvard University is what appears to be an elegant drawing of a tree. Thin multicolored lines snake upward in parallel, then branch out in twos and threes, their tips capped by tiny leaves. Lichtman is a neuroscientist, and the image is the first comprehensive wiring diagram of part of the mammalian nervous system. The lines denote axons, the long, hairlike extensions of nerve cells that transmit signals from one neuron to the next; the leaves are synapses, the connections that the axons make with other neurons or muscle cells.

Probing the salamander genome reveals clues to its remarkable ability to regrow damaged limbs and organs.

In its own way, the axolotl salamander is a mighty beast. Chop off its leg, and the gilled creature will grow a new one. Freeze part of its heart, and the organ will form anew. Carve out half of its brain, and six months later, another half will have sprouted in its place. “You can do anything to it except kill it, and it will regenerate,” says Gerald Pao, a postdoctoral researcher at the Salk Institute for Biological Studies, in La Jolla, CA.

That extraordinary power of regeneration inspired Pao to probe the axolotl salamander’s DNA. Despite decades of research on the salamander, little is known about its genome. That began to change last year, when Pao and his collaborators won one billion bases’ worth of free sequencing from Roche Applied Science, based in Indianapolis. Now that the data is in, scientists can finally begin the hunt for the genetic program that endows the animal with its unique capabilities. [ read more ]

New research is linking dopamine to complex social phenomena and changing neuroscience in the process.

Read Montague is getting frustrated. He’s trying to show me his newest brain scanner, a gleaming white fMRI machine that looks like a gargantuan tanning bed. The door, however, can be unlocked only by a fingerprint scan, which isn’t recognizing Montague’s fingers. Again and again, he inserts his palm under the infrared light, only to get the same beep of rejection. Montague is clearly growing frustrated — “ I can’t get into my own scanning room!” he yells, at no one in particular — but he also appreciates the irony. A pioneer of brain imaging, he oversees one of the premier fMRI setups in the world, and yet he can’t even scan his own hand. “I can image the mind,” he says. “But apparently my thumb is beyond the limits of science.” [ read more ]

“Everyone has assumed we age by rust. But how do you explain animals that don’t age? Some tortoises lay eggs at the age of 100, there are whales that live to be 200 and clams that make it past 400 years.”

Stuart Kim, PhD, Stanford University professor of developmental biology and genetics

Prevailing theory of aging challenged by Stanford University Medical School researchers. Their discovery contradicts the prevailing theory that aging is a buildup of tissue damage similar to rust. The Stanford findings suggest specific genetic instructions drive the process. If they are right, science might one day find ways of switching the signals off and halting or even reversing aging.

1. Aerogel holds 15 entries in the Guinness Book of Records, more than any other material. Sometimes called “frozen smoke”, aerogel is made by the supercritical drying of liquid gels of alumina, chromia, tin oxide, or carbon. It’s 99.8% empty space, which makes it look semi-transparent. Aerogel is a fantastic insulator — if you had a shield of aerogel, you could easily defend yourself from a flamethrower. It stops cold, it stops heat. You could build a warm dome on the Moon. Aerogels have unbelievable surface area in their internal fractal structures — cubes of aerogel just an inch on a side may have an internal surface area equivalent to a football field. Despite its low density, aerogel has been looked into as a component of military armor because of its insulating properties. [ read more ]

A fast screening method could help separate the good from the bad.

In light of mounting concerns regarding the potential toxicity of some nanomaterials, scientists have designed a rapid screening tool to help predict which ones are likely to be harmful. Hundreds of nanotechnology-based products are already on the market–in everything from sunscreens and cosmetics to paints and car bumpers–and many more are in the pipeline. However, studies assessing the safety of nanomaterials are limited. As a result, scientists and policy makers have been calling for more systematic reviews of the risks that these nanoscale materials might pose to human health. [ read more ]

“This doesn’t look like a hospital,” says Ruben Toral, showing me around. “It feels more like a hotel or an upscale mall.” After studying the gleaming lobby of Bumrungrad International for a minute or two, I’m inclined to agree. Americans in shorts recline across from Arab couples in flowing white dishdashas and black abayas, the latter accessorized with designer handbags and sunglasses. We’re in Bangkok in August, when even the asphalt is overripe and malodorous, but the only scent inside is a faint whiff of espresso from the Starbucks in the corner.

Toral is responsible for luring that cosmopolitan clientele here, thousands of miles from home, for a knee replacement or a triple bypass or even just a checkup. Before he arrived in 2001 as Bumrungrad’s marketing director, “we were a Thai hospital serving a Thai community,” he says. “Now we’re an international hospital that just happens to be in Thailand.” [ read more ]
