E começo já com a notícia inquietante, Cientistas que afirmam que se pode projectat o "ego" duma pessoa para outros corpos e até um terceiro braço(!)

Scientists claim that 'self' can relocate to other bodies, or be made to include a third arm
By Ben Coxworth
09:29 February 24, 2011

For millennia, philosophers have debated whether or not the self exists solely in the mind, the body, or both. Well, it's unclear whether this will help clear things up or just muddy the waters further, but Swedish neuroscientists are now claiming that the human brain can add outside objects such as a third arm to one's physical sense of self, and that people can even mentally project their "self" out of their own body and into someone else's. If these findings hold up, the implications for virtual reality, robotics and prostheses could be substantial.

Papel prateado (com prata, mesmo) pode servir para purificar a àgua!

Silver-coated paper could be used for emergency water purification
By Ben Coxworth

14:46 February 24, 2011
Silver is well-known for its antibacterial qualities, which has led to the use of silver nanoparticles in devices such as an experimental water filtration system developed by Stanford University. That system is intended as a relatively permanent setup, and it requires a small electrical current. Researchers from Montreal’s McGill University, however, have come up with a silver-based water treatment system that could conceivably be used instantly, in any place and at any time. While not intended as a routine method of killing water-borne bacteria, it could be very useful in emergency situations such as disaster relief.

HyperSolar concentrator could boost solar cell output by 400 percent

By Ben Coxworth

14:24 February 17, 2011

Solar cells are the most expensive part of a solar panel, so it would follow that if panels could produce the same amount of electricity with less cells, then their prices would come down. In order for panels to be able to do so using existing cell technology, however, they would need to get more light to the fewer cells that they still had. Mounting the panels on the end of vertical poles to get them closer to the sun is one possible approach, that might work in the town of Bedrock or on Gilligan’s Island. A better idea, though, is to apply a clear layer of solar concentrators to the surface of a panel – and that’s just what HyperSolar intends to do.

Can testosterone improve cognition in older women?

By Mary Panjari

21:01 February 17, 2011

For women, the onset of midlife brings with it an array of distressing symptoms related to changes in hormone levels. The risk of dementia increases with age – particularly after the mid-60s – memory loss is a frequent complaint and quality of life is compromised as a result. Using a novel "patchless" patch method of drug delivery, researchers at the Women’s Health Research Program Monash University, Australia, have been investigating whether restoring testosterone levels in older women to those of younger women will improve brain function and ultimately protect against dementia.

Researchers stumble on potential new treatment for hair loss


By Darren Quick

21:29 February 17, 2011

While conducting research into brain-gut interactions, a team led by researchers from UCLA and the Veterans Administration may have inadvertently stumbled across a new treatment for hair loss. During an investigation into the affect of stress on gastrointestinal function, the researchers believe they may have found a chemical compound that induces hair growth by blocking a stress-related hormone associated with hair loss.

Um beija-flor robótico que voa por todo o lado!|

AeroVironment, the California-based company behind the largest, highest and longest flying unmanned aircraft system (UAS), the Global Observer, has now achieved a remarkable technical milestone with a much smaller aircraft. With its "Nano Hummingbird" the company has for the first time achieved controlled precision hovering and fast-forward flight of a two-wing, flapping wing aircraft that carries its own energy source and relies only on its flapping wings for propulsion and control.

The hand-made final concept demonstrator Nano Hummingbird has a wingspan of 16 cm (6.5 in) and weighs just 19 g (2/3 oz), which is less than the weight of a AA battery. Into this tiny and lightweight package the AeroVironment UAS team has managed to cram all the systems required for flight, including batteries, motors, communications systems and even a video camera.

The fat wheeled eniCycle, the stylish and graceful U3 from Honda or the slightly scary prospect of the UnoMoto have all shared more in common than being one-wheeled, self-balancing personal transport solutions.

It has a useful carry handle and fold-away foot platforms, is gyro-stabilized and the Li-ion batteries offer a range of about 12 miles between charges.

A importância da àgua

Isto é importante...

A importância da água no nosso planeta é inigualável e significado de vida, dai a frase “água fonte de vida“, sendo também fundamental para o nosso organismo, a água tem um papel importante na nossa saúde , tendo a água diversas funções como:

* A água transporta pelo nosso organismo os nutrientes e os detritos celulares resultantes dos processos metabólicos. A água transporta também outras substâncias, como hormonas, enzimas e células sanguíneas.
* A água é um excelente solvente e meio de suspensão, muitas substâncias dissolvem-se ou chegam mesmo a estar suspensas, permitindo que existam reacções químicas para formar novos compostos. Estas propriedades facilitam também a eliminação das toxinas acumuladas no nosso organismo através da urina.
* Outro dos benefícios da água tem a ver com o seu efeito lubrificante nas nossas articulações. A desidratação nas cartilagens provoca movimentos abrasivos quando existe um qualquer movimento ósseo resultante de uma deficiente hidratação das extremidades ósseas.
* A água é um dos reguladores de temperatura do nosso organismo.
* A água é essencial para todos os processos fisiológicos de digestão, absorção assimilação e de excreção.

Scientists create a real-life thinking cap

by Terrence Aym

Scientists at the University of Sydney's Center for the Mind in Australia have created a real-life thinking cap. They did it by jolting the brain with electricity flowing from a strange headpiece with rubber straps and twisted tubes.

Although to get a real brainstorm users must wear the bizarre device on their heads, researchers insist its worth it. They believe it will help people boost their creativity and insight.

It works by suppressing the electrical flow in the left side of the brain and forcing the right side to pick up the slack. Theoretically, the increased use of the right half of the brain—the part that drives creativity and imagination-will boost the user's right brain power.

The photo comes courtesy of NASA's twin STEREO (Solar TErrestrial RElations Observatory) spacecraft, which aligned exactly opposite each other around the sun to capture the image.

The ability to see the whole sun, front to back, will allow scientists to better understand complicated solar weather patterns and plan for future robotic or crewed spacecraft missions throughout the solar system, researchers said.
