Brachistochrone is a Greek word which translates to the shortest time, and it refers to one of the questions posed by one of the Bernoulli’s brothers; Johann Bernoulli. If you want to move from point A to B in the quickest time possible what is the shortest time you can take. Most people will assume that the straight line will be the shortest and will take the least time which isn’t true.

Forever Young? There’s Officially An Anti-Aging Pill For Dogs
Posted by Shane Hinshaw in categories: biotech/medical, life extension
In Brief:
- A drug seems to be showing signs of reversing the effects of aging in dogs and mice. Studies are being conducted on the effectiveness in humans.
- The drug has some major side effects linked to it and there is no guarantee it will be as effective in humans.
Aging is a spectre we all must face one day…but is this the way that it will always be? Medical researchers hope to delay or even reverse the onset of aging, and some are already claiming that they’ve made inroads to immortality.

Nanometric Imprinting on Fiber
Posted by Karen Hurst in categories: biotech/medical, materials
Researchers at EPFL’s Laboratory of Photonic Materials and Fibre Devices, which is run by Fabien Sorin, have come up with a simple and innovative technique for drawing or imprinting complex, nanometric patterns on hollow polymer fibers. Their work has been published in Advanced Functional Materials.
The potential applications of this breakthrough are numerous. The imprinted designs could be used to impart certain optical effects on a fiber or make it water-resistant. They could also guide stem–cell growth in textured fiber channels or be used to break down the fiber at a specific location and point in time in order to release drugs as part of a smart bandage.

Earth makes its own water deep in the mantle, study finds
Posted by Karen Hurst in categories: computing, space
Scientists have long been perplexed by the mystery of how Earth got its water, with many suggesting it formed after icy comets collided with our planet billions of years ago.
But, a new study suggest it may have been born within Earth itself.
New computer simulations show how reactions between liquid hydrogen and quartz in the upper mantle could form water – and the researchers say this could trigger earthquakes deep below the surface.

U.S. scientists could have squeezed hydrogen all the way into a potentially superconducting metal
Posted by Karen Hurst in categories: computing, physics, transportation
For over 80 years, scientists all round the world have dreamt of converting hydrogen, the first element of the periodic table, into a metal. And now, after hundreds of failed attempts in the history, scientists from U.S. have finally managed the feat by compressing hydrogen so profoundly that it has turned into a metal!
Back in 1935, physicists Hillard Bell Huntington and Eugene Wigner proposed a theory that hydrogen, which normally exists in a gaseous state, could transform into metallic state once exposed to extreme pressure. Since then many scientists have tried to practically prove the theory — albeit unsuccessfully. However, this discovery, which was published in the journal ‘Science’ on Thursday, is the first confirmation of the theory.
The metallic hydrogen is a potential superconductor, a material with extraordinary electricity conducting capabilities, a quality which makes it a very expensive metal. But it holds the ability of revolutionizing the world of ultra fast super computers, high speed levitation trains, or any other thing which involves conduction of electricity.

Virtual reality ‘could help treat vertigo’
Posted by Shane Hinshaw in category: virtual reality
Virtual reality could be used to diagnose and treat visual vertigo, according to a team of Cardiff University psychologists.
People with the condition suffer from dizziness and nausea and often cite places with repetitive visual patterns, such as supermarkets, as the trigger.
A team of psychologists is working to develop virtual environments to help with diagnosis and rehabilitation.

DARPA teams with Flex Logix to develop FPGA technology for government agencies designing ICs
Posted by Karen Hurst in categories: computing, government
DARPA licenses embedded FPGA tech for U.S. government projects.
The Defense Advanced Research Projects Agency, also known as DARPA, just signed an agreement to work with Flex Logix, a semiconductor start-up, to develop the young company’s EFLX embedded FPGA technology for use by any company or government agency designing integrated circuits for the U.S. government.
FPGAs have been widely used in systems since the 1980s and, at the system level, provide flexibility and programmability different from what processors can do. Many years ago, ARM took the idea of a processor chip and offered a processor architecture, which could be embedded in chips. Although it took time, embedded processors are now nearly ubiquitous. Flex Logix is doing the same for embedded FPGAs.
