BIOENGINEERS dream of growing spare parts for our worn-out or diseased bodies. They have already succeeded with some tissues, but one has always eluded them: the brain. Now a team in Sweden has taken the first step towards this ultimate goal.

Growing artificial body parts in the lab starts with a scaffold. This acts as a template on which to grow cells from the patient’s body. This has been successfully used to grow lymph nodes, heart cells and voice boxes from a person’s stem cells. Bioengineers have even grown and transplanted an artificial kidney in a rat.

Growing nerve tissue in the lab is much more difficult, though. In the brain, new neural cells grow in a complex and specialised matrix of proteins. This matrix is so important that damaged nerve cells don’t regenerate without it. But its complexity is difficult to reproduce. To try to get round this problem, Paolo Macchiarini and Silvia Baiguera at the Karolinska Institute in Stockholm, Sweden, and colleagues combined a scaffold made from gelatin with a tiny amount of rat brain tissue that had already had its cells removed. This “decellularised” tissue, they hoped, would provide enough of the crucial biochemical cues to enable seeded cells to develop as they would in the brain.

a TREATMENT to cure or halt dementia by 2025 is “within our grasp”, Prime Minister David Cameron said yesterday, as he announced a doubling in UK funding for research.

Mr Cameron was addressing scientists, politicians and campaigners from around the world who have gathered in London for a dementia summit called by the UK as part of its year-long chairmanship of the G8.

With the World Health Organisation (WHO) forecasting that the number of dementia sufferers will almost double worldwide every two decades, Mr Cameron has said he wants UK government investment in dementia research to rise from £66 million in 2015 to £122m in 2025, with similar increases from the commercial and charitable sectors.

A soldier whose arm was blown off by a rocket-propelled grenade in Afghanistan has become the first person in the UK to master a prosthetic limb controlled by thought.

Corporal Andrew Garthwaite, 26, has spent two years learning how to move the arm and grip objects after a six-hour operation to have the limb wired into his body at a medical facility in Vienna.

The science-fiction-like world of 3D printing is starting to get some very real attention from Wall Street. This week Jefferies initiated coverage on the sector with “buy” ratings on three of its five major players – 3D Systems, Stratasys, and ExOne – and “holds” on the other two, Arcam and voxeljet. These companies could revolutionize mass manufacturing, Jefferies says, and could even get competition from a bellwether of the traditional printing industry: Hewlett Packard.

In a comprehensive, 97-page research note, Jefferies analyst Peter Misek writes that while 3D printing has been around since the 1980′s, a confluence of factors ranging from improvements in printer speeds to a greater availability of software that produces the digital designs used to create 3D printouts have brought the sector into the mainstream, and it will only continue its climb in years to come.

“Our base scenario envisions an eventual expansion of consumer 3D printers from its hobbyist base into a prototyping tool for ‘creative consumers’ and for home printing of toys to become mainstream,” Misek writes, defining ‘creative consumers’ as those who might favor the craft site Etsy. He says that 3D printing could eventually take a $12.5 billion chunk out of the $22 billion U.S. toy market for its ability to recreate action figures, building sets, craft supplies and more. While some companies insist this development is around the corner — 3D Systems is trying to get a $500 consumer 3D printer on the market in time for the 2014 holiday season — Misek thinks such products won’t debut until 2015 or 2016 at the earliest.

A venture capitalist, a former regulator, a lawyer and a pair of entrepreneurs — Bitcoin evangelists all — gathered on Tuesday in the private dining room of an upscale Manhattan restaurant to discuss their vision of a world in which the currency plays a role in mainstream finance.

It may be a far-fetched notion — Bitcoin, despite the attention it has received in recent months, is still largely a plaything for speculators online, with stomach-turning price swings — but it is one that these men have bet millions of dollars can be achieved.

Shane McGlaun,

DARPA has been hosting a Robotics Challenge since last year that challenged some participants to create robots that can be used in the real world. The official name for the Valkyrie robot given to it by NASA is R5. The bot stands 1.9 meters tall and weighs in at 125 kilograms. The robot has 44 degrees of freedom and is powered by batteries.

The robot was created in cooperation with the NASA Johnson Space Center in Houston, the University of Texas, and Texas A&M universities. Funding for the robot was granted by the State of Texas. The first competition for the DARPA robotics contest will happen later this month.

This is an excerpt from the conclusion section of, “…NASA’s Managerial and Leadership Methodology, Now Unveiled!..!” by Mr. Andres Agostini, that discusses some management theories and practices. To read the entire piece, just click the link at the end of this illustrated article and presentation:

In addition to being aware and adaptable and resilient before the driving forces reshaping the current present and the as-of-now future, there are some extra management suggestions that I concurrently practice:

1. Given the vast amount of insidious risks, futures, challenges, principles, processes, contents, practices, tools, techniques, benefits and opportunities, there needs to be a full-bodied practical and applicable methodology (methodologies are utilized and implemented to solve complex problems and to facilitate the decision-making and anticipatory process).

The manager must always address issues with a Panoramic View and must also exercise the envisioning of both the Whole and the Granularity of Details, along with the embedded (corresponding) interrelationships and dynamics (that is, [i] interrelationships and dynamics of the subtle, [ii] interrelationships and dynamics of the overt and [iii] interrelationships and dynamics of the covert).
