Scientists discover natureâs algorithm for intelligence
Posted by Shailesh Prasad in categories: biotech/medical, genetics, information science, mathematics, neuroscience
But if there is some kind of unifying computational principle governing our grey matter, what is it? Dr. Tsien has studied this for over a decade, and he believes heâs found the answer in something called the Theory of Connectivity.
âMany people have long speculated that there has to be a basic design principle from which intelligence originates and the brain evolves, like how the double helix of DNA and genetic codes are universal for every organism,â Tsien said. âWe present evidence that the brain may operate on an amazingly simple mathematical logic.â
The Theory of Connectivity holds that a simple algorithm, called a power-of-two-based permutation taking the form of n=2i-1 can be used to explain the circuitry of the brain. To unpack the formula, letâs define a few key concepts from the theory of connectivity, specifically the idea of a neuronal clique. A neuronal clique is a group of neurons which âfire togetherâ and cluster into functional connectivity motifs, or FCMs, which the brain uses to recognize specific patterns or ideas. One can liken it to branches on a tree, with the neuronal clique being the smallest unit of connectivity, a mere twig, which when combined with other cliques, link up to form an FCM. The more complex the idea being represented in the brain, the more convoluted the FCM. The n in n=2i-1 specifies the number of neuronal cliques that will fire in response to a given input, i.

Replacing Lost Stem Cells Reverses Some of the Aging Process
Posted by Steve Hill in categories: biotech/medical, life extension
A research team led by Dr. Cai at the Albert Einstein college of medicine have shown that stem cells in the hypothalamus influence how fast we age. The new research, shown in mice, may lead to approaches that delay or even prevent age-related diseases[1].

Healthy food isnât always tasty. But with regards to bananas, this isnât the case. Which is why itâs doubly pleasing to learn that they not only bring satisfaction to your taste buds but also a great many benefits to your health.
We at Bright Side have gathered together all the evidence showing why eating just two bananas a day can seriously improve your health.

Why the super-rich are ploughing billions into the booming âimmortality industryâ
Posted by Derick Lee in categories: bioengineering, biotech/medical, computing, life extension, mapping, neuroscience
Imagine a world in which youâre 90 years old and nowhere near middle-aged. An app on your phone has hacked your DNA code, so you know exactly when to go to the doctor to receive gene therapy to prevent all the diseases you donât yet have. A microchip in your skin sends out a signal if youâre at risk of developing a wrinkle â so you step out of the sun and hotfoot it to your dermatologist. Every evening you sync your brain-mapping device with The Cloud, so even if you were caught up in a fatal accident youâd still be able to cheat death â every detail of your life would simply be downloaded to one of the perfect silicon versions youâd had made of yourself, ensuring you last until at least your 1,000th birthday.
This may sound like science fiction but it could be your fate â provided you can afford it. If current research develops into medicine, in the London of the future the super-rich wonât simply be able to buy the best things in life, theyâll be able to buy life itself by transforming themselves into a bio-engineered super-race, capable of living, if not forever, then for vastly longer than the current UK life expectancy of 81 years.
The science of turning back the clock has never been more advanced. In Boston, a drug capable of reversing half a lifetime of ageing in mice is about to be tested on humans in a medical trial monitored by NASA. NMN is a compound found naturally in broccoli which boosts levels of NAD, a protein involved in energy production that depletes as we get older. Professor David Sinclair, who headed up the initial research at Australiaâs University of New South Wales, doses himself with 500mg daily, and claims that he has already become more youthful. According to blood tests analysing the state of the 48-year-oldâs cells, prior to taking the pills Sinclair was in the same physical shape as a 57-year-old, but now heâs â31.4â.

Robot flying taxi takes its first autonomous flight
Posted by Shane Hinshaw in categories: robotics/AI, transportation
Formerly known as the âAir Mule,â this is a flying taxi, or maybe a future unmanned ambulance.
Urban Aeronautics
Nine years ago, the Air Mule was an almost-believable concept: a flying robot taxi that could get people out of dangerous battlefields without endangering a pilot or crew. It was the exact sort of gizmo one expects from Popular Science: an amazing machine of the future, almost like a flying car, that seemed plausible but just out of reach.
