Alzheimer’s Disease: Is It Time To Look Beyond Amyloid?

Posted by in categories: biotech/medical, neuroscience

While billions have now been spent on researching dementia in its various forms, progress is still limited and the underlying triggers are still not clear. The majority of research over the past 30 years has revolved around targeting the amyloid plaques that build up in the disease, but this has resulted in limited success. Is it time to focus resources on other hypotheses instead?

The real problem with tackling these conditions is the sheer complexity of the brain and biology. Research is usually a trial and error process filled with intelligent guesswork, but this means it can often take a great deal of time to establish what’s actually going wrong. The cause or effect conundrum is a significant roadblock in research and working out which aspects drive a disease and which are a result of another malfunction can take serious resources and time. When researchers first began analysing Alzheimer’s patients, perhaps the most obvious feature was the now famous amyloid plaque, but while amyloid may seem like a clear culprit because it’s so clearly out of place, it could easily be a smokescreen; the reason why it appears at all may be far more relevant than the plaque itself.

Passive exoskeleton to lighten the load for soldiers

Posted by in category: cyborgs

Soldiers often have to carry over 100 lb (45 kg) of gear in a backpack, for several hours at a time. That’s why engineers at the Australia’s Department of Defence have developed a new exoskeleton, that diverts two thirds of pack weight directly to the ground.

This Social Network Turns Your Personality Into an Immortal Artificial Intelligence

Posted by in categories: futurism, robotics/AI

Interesting…but I’d rather it was ME that was immortal, not some virtual copy.


By learning everything there is to know about you and your online habits, social network ETER9 promises a kind of digital immortality wherein an artificially intelligent agent continues to post on your behalf long after you’re dead. The future is creepier than we ever imagined.

ETER9, a startup launched by Portuguese developer Henrique Jorge, is still in the beta phase, but 5,000 people have already signed up for the service. It currently features a Facebook-like newsfeed, and a “cortex” that works much like a Facebook wall. But that’s where the similarities end.

Kid Gets Awesome New Bionic Hand, Reminds Us Not Everything is Garbage

Posted by in categories: cyborgs, transhumanism

The stock market is tanking, North and South Korea are on the brink of war, and a cartoon character from a dystopian future is the most popular candidate for US President at the moment. But don’t despair. While most things are garbage, there are some things in the world that aren’t. Like this adorable kid who just got his own high-tech bionic hand.

Nine-year-old Josh Cathcart was often bullied in school for having just one hand. But he’s about to become the coolest kid in school, thanks to his new i-limb, developed by a company called Touch Bionics. The hand can be programmed via an iPad app.

Trio create artificial magnetic wormhole

Posted by in category: physics

(Phys.org)—A trio of physicists with the Autonomous University of Barcelona has built what they claim is the first artificial magnetic wormhole. In their paper published in the journal Scientific Reports, Jordi Prat-Camps, Carles Navau and Alvaro Sanchez describe how they built the device and why they believe it might prove useful in building a more user-friendly MRI machine.

Art Or Design?: Welcome To The Improvisational Carpentry Of Nicolás Aracena Müller — By Diana Budds | Fast Company

Posted by in category: media & arts

“Müller, who is based in Chile, calls the concept improvisational carpentry. He traveled to New York and wandered the city streets and dove into dumpsters searching for materials he could turn into pieces that are part sculpture, part theater, and part design. He believes that working with cast-off items reflects the city’s character. (The mottled woods certainly captures New York’s tougher side.)”

Physicists Unveil First Quantum Interconnect

Posted by in categories: computing, electronics, physics, quantum physics

One of the unsung workhorses of modern technology is the humble interconnect. This is essentially a wire or set of wires that link one part of an electronic system to another. In ordinary silicon chips, interconnect can take up most of the area of a chip; and the speed and efficiency with which information can travel along these interconnects, is a major limiting factor in computing performance.

So it’s no wonder that physicists and engineers are creating new generations of interconnect that will become the backbone of information processing machines of the future.

Exotic Pentaquark Particle Discovery & CERN’s Massive Data Center

Posted by in categories: big data, engineering, particle physics, physics, science


July, 2015; as you know.. was the all systems go for the CERNs Large Hadron Collider (LHC). On a Saturday evening, proton collisions resumed at the LHC and the experiments began collecting data once again. With the observation of the Higgs already in our back pocket — It was time to turn up the dial and push the LHC into double digit (TeV) energy levels. From a personal standpoint, I didn’t blink an eye hearing that large amounts of Data was being collected at every turn. BUT, I was quite surprised to learn at the ‘Amount’ being collected and processed each day — About One Petabyte.

Approximately 600 million times per second, particles collide within the (LHC). The digitized summary is recorded as a “collision event”. Physicists must then sift through the 30 petabytes or so of data produced annually to determine if the collisions have thrown up any interesting physics. Needless to say — The Hunt is On!

The Data Center processes about one Petabyte of data every day — the equivalent of around 210,000 DVDs. The center hosts 11,000 servers with 100,000 processor cores. Some 6000 changes in the database are performed every second.
