Neuron Light Switch Now Goes “On” and “Off” | MIT Technology Review

Neuron Light Switch Now Goes “On” and “Off” | MIT Technology Review | Science, Technology, and Current Futurism | Scoop.it
A new optogenetic protein gives neuroscientists more control over brain circuits.

 

Optogenetics is a recent innovation in neuroscience that gives researchers the ability to control the activity of neurons with light. With this powerful tool, researchers are teasing apart the biological basis of memory, behavior, and disease (see “Scientists Make Mice ‘Remember’ Things That Didn’t Happen” and “An On-Off Switch for Anxiety,”). But for the first several years of this technology’s existence, the proteins that scientists added to neurons to make them react to light were only good at activating neurons. That limited researchers’ ability to understand neuronal circuits, sets of interconnected neurons that are thought to control behavior and, when misfiring, to underlie many brain conditions. Problems can arise from any imbalance in circuit activity, whether too much or too little.

Programming smart molecules: Machine-learning algorithms could make chemical reactions intelligent

Programming smart molecules: Machine-learning algorithms could make chemical reactions intelligent | Science, Technology, and Current Futurism | Scoop.it
Computer scientists at the Harvard School of Engineering and Applied Sciences (SEAS) and the Wyss Institute for Biologically Inspired Engineering at Harvard University have joined forces to put powerful probabilistic reasoning algorithms in the...
Sharrock's insight:

Adams and Napp designed a tool that can take probabilistic representations of unknowns in the world (probabilistic graphical models, in the language of machine learning) and compile them into a set of chemical reactions that estimate quantities that cannot be observed directly. The key insight is that the dynamics of chemical reactions map directly onto the two types of computational steps that computer scientists would normally perform in silico to achieve the same end.

Super Hero Gadgets You Can Actually Buy

Super Hero Gadgets You Can Actually Buy | Science, Technology, and Current Futurism | Scoop.it

With less than a week until NYC Comic Con, ideas begin to spark and many wonder what type of super hero they would want to be.  Flying, x-ray vision, super human strength, and walking on walls are some of the super powers most people would dream of having. Luckily for the dreamers, technology has been improving dramatically over the years making these fantasies attainable.  Whether you want to be the classic caped crusader protecting Gotham City or a smooth secret agent like James Bond, special gadgets we’ve seen our favorite heroes use time and time again have been developed for the modern man.

Sharrock's insight:

Jetpacks, better nightvision, robotic suits, etc. To misquote Jack Nicholson's Joker question, "Where do they get such wonderful toys?"

Is Science The New Latin?!

Is Science The New Latin?! | Science, Technology, and Current Futurism | Scoop.it
Most scientists aren’t natural communicators. Scientific discoveries aren’t written in Latin, but they may as well be. In this environment, creationism and denialism thrive…
Sharrock's insight:

The challenge here is to help the general public understand concepts that defy personal experience. Too many machines come between what is being studies and what a person can actually see. According to a some lectures I am listening to, it took Einstein 20 years to understand the quantum world, and in the end, he still had problems with accepting concepts like entaglement, even when his own investigations "uncovered" this concept. Technology is a way to approach that understanding, but technology is just "what works". It isn't PROOF of causation, of underlying systems of causation (ie, metaphysics). Then there is the math involved in some of these concepts. It just seems clear to me that in the pursuit of  STEM competence, engineering and technology is concrete so easier accept because the thing works. Creating the technology with engineering is acceptable even though few people will connect particular engineers to particular technologies. Intead, they connect organizations to the tech development--which is another disconnect. Coding for software is another area that is quickly approaching the magickal. People may learn coding basics, but the concepts involved in adaptive systems, expert systems, and the variousl levels of artificial intelligence seem to involve so many academic disciplines and collaboration that this too may be beyond the general public's understanding.

The Navy's UAV sets down on the USS George H. W. Bush.

 

Check off another box for the U.S. Navy's jet fighter-sized UAV. Two months after the semi-autonomous X-47B executed its first catapult carrier takeoff, the Navy has now released the footage of the plane completing its first arrested landing. The plane touched down on the USS George H.W. Bush off the coast of Virginia today. It's the first unmanned carrier landing for the Navy.

The State Grid Corporation of China Is Running a Smart-Grid Project Using Passive Optical Networking Technology | MIT Technology Review

The State Grid Corporation of China Is Running a Smart-Grid Project Using Passive Optical Networking Technology | MIT Technology Review | Science, Technology, and Current Futurism | Scoop.it
As well as making the grid more reliable and efficient, the technology could deliver high-speed Internet, TV, and telephony.
Sharrock's insight:

From article, "why it matters": "The smart grid could make electricity cheaper and more reliable, and China’s experience may be an important test case."


However, for now, it might not happen in the US: Some academics have also voiced skepticism that the approach could work in the United States. Michael Caramanis, a professor in Boston University’s College of Engineering, says the synergy between fiber and smart grids is debatable. “It is not clear that the PON communications tech is a direction that we should mandate and subsidize in the U.S.,” he says.
