Stimulating Neural Circuits with Magnetism

Posted by in category: neuroscience

Interesting and I remember coming across similar research a few years ago.


Brain stimulation might sound like some Frankensteinian demonstration from a Victorian science fair. But in reality, it is a contemporary technique making a huge impact in neuroscience by addressing a longstanding limitation of traditional methods for investigating human brain function. Such techniques, like EEG and fMRI, can only be used to infer the effects of a stimulus or task on brain activity, and not vice versa. For example, a scientist might use EEG to study the effect of a task like arm movement on brain activity, but how can one study the effect of brain activity on arm movement?

Today, noninvasive brain stimulation techniques such as transcranial magnetic stimulation (TMS) are offering alternatives to old paradigms. TMS can excite or suppress underlying brain tissue safely and ethically, allowing researchers to study causal relationships between brain circuits and behavior. What’s more, TMS may have therapeutic value in treating brain disorders such as depression.

Scientists use light to control the logic networks of a cell (w/video)

Posted by in categories: biotech/medical, genetics, neuroscience

Luv this.


Proteins are the workhorse molecules of life. Among their many jobs, they carry oxygen, build tissue, copy DNA for the next generation, and coordinate events within and between cells. Now scientists at the University of North Carolina at Chapel Hill have developed a method to control proteins inside live cells with the flick of a switch, giving researchers an unprecedented tool for pinpointing the causes of disease using the simplest of tools: light.

Nano-chimneys can cool circuits

Posted by in categories: chemistry, nanotechnology

Very cool.


A few nanoscale adjustments may be all that is required to make graphene-nanotube junctions excel at transferring heat, according to Rice University scientists.

The Rice lab of theoretical physicist Boris Yakobson found that putting a cone-like “chimney” between the graphene and nanotube all but eliminates a barrier that blocks heat from escaping.

Tiny 3D printed biobots could dispense drug doses from inside your body

Posted by in categories: 3D printing, biotech/medical, engineering

Samuel Sia, a professor of biomedical engineering at New York City’s Columbia University, has developed a 3D printed biobot that can be implanted in the body to release controlled doses of drugs. The amazing device can be controlled from outside the body using only magnets.

Grid Down: Prepare for Electronic Interference As Cyber World War Dawns

Posted by in categories: energy, internet

cyber-attack

The revival of the Cold War attitudes between the U.S. and Russia are just the beginning of the an expanding scene of digital vulnerabilities and shocks to the system that could shut down the grid, cut off grocery and supply lines or leave millions without power in the cold. With global tension, the pretext could come from anywhere:

‘Out-of-the-Box’ Approaches Can Help Combat Antibiotic Resistance

Posted by in categories: biotech/medical, military

Is it possible to kill bacteria with bacteria?

This is the unorthodox question posed by a team of researchers funded by the Defense Advanced Research Projects Agency (DARPA)—a research and development organization within the U.S. Department of Defense—that is exploring whether an unusual type of bacteria that eats other bacteria could be a new weapon in the fight against drug-resistant infections.

Known as the Pathogen Predator program, the DARPA initiative (led by Dr. Barry Pallotta) is part of a growing effort to seek new and innovative ways to defeat drug-resistant superbugs, which are rapidly evolving to beat even our most powerful antibiotics.

Jeff Bezos tweets his vote of support for constructing a ‘superhighway in space’

Posted by in categories: space, transportation

What should Donald Trump have NASA do? Today Amazon billionaire Jeff Bezos voiced his support for the idea that the space agency should help build a “highway in the sky” analogous to the interstate highway system that President Dwight Eisenhower ramped up in the 1950s.

The backing came in the form of an eight-word tweet, accompanied by a link to an article by Howard Bloom appearing in Salon (and as a guest blog posting on Scientific American’s website as well).

The Future Of Encryption

Posted by in categories: business, cybercrime/malcode, encryption, engineering, internet, quantum physics

QC in the mainstream is definitely viable less than 7 yrs. and possible within 5 yrs. However, I have a friend who even believes we’re looking at 3 years.


Internet security, once considered to be strictly in the domain of the wonkiest tech experts, has become central to public discourse over the past year. Besides the attacks on the DNC, even tech savvy business like Snapchat, Oracle and Verizon Enterprise Solutions have had significant breaches in the last year.

For the most part, these attacks were preventable. Often, hackers use a technique called social engineering, to trick people into allowing them into a system. Other times, they exploit a vulnerability in software to give them access to confidential data. In most cases, more stringent procedures can prevent attacks.

Synthego bags $41M to grow CRISPR synthetic RNA kit biz

Posted by in categories: bioengineering, biotech/medical, business, robotics/AI

Nice.


Synthetic RNA kit business Synthego has raised $41 million to step up its efforts to make CRISPR gene editing easier and more accurate. The West Coast startup relied heavily on tech VCs for the cash, but also gained validation from having CRISPR pioneer Jennifer Doudna invest in its business.

Redwood City, CA-based Synthego exited stealth in August, four years after it was set up by two former SpaceX computer engineers. In those early years, which were bankrolled by an $8.3 million investment in 2013, Synthego established an automated manufacturing process for guide RNA products that it thinks sets it apart from larger competitors in terms of cost, turnaround time and editing efficiency.
