Using a few wires and sponges, in ordinary homes around the world, people are trying to hack their own minds. Thanks to a 2002 study that found a link between brain transcranial direct current stimulation and better motor task performance, “do-it-yourself” brain stimulation has become a growing movement among those who want to improve a whole host of cognitive and psychological functions, including language skills, mood and memory.

Scientists are split about the practice: Some say that while brain stimulators might not work as advertised (the ones available to purchase can cost hundreds of dollars), these devices are more-or-less safe. Others think the technique could cause damage, even if done in a controlled, clinical setting. Though “brain hackers” may be disappointed with their own results, their hope about the technology’s potential is rooted in an increasing amount of evidence.

The earliest clinical uses of brain stimulation date back to nearly 2000 years ago, when physician Scribonius Largus recommended the use of electric rayfish to treat headaches and neuralgia. By the 1980s, researchers began designing non-invasive stimulators and brain implants for treating specific diseases. Transcranial direct current stimulation (tDCS) — a non-invasive treatment that uses direct electrical currents to stimulate specific parts of the brain — has been shown, in a few small studies, to purportedly improve language skills, boost memory and strengthen reflexes. Transcranial magnetic stimulation (TMS), another non-invasive procedure, is sometimes used to treat depression. And clinical trials are underway to see if stimulating the brain can treat other medical conditions, such as Parkinson’s.

Physicists have built a ring in which pulses of light whip circles around each other and the normal rules that govern light’s behavior no longer apply.

Under normal circumstances, light displays certain kids of physical symmetry. First, if you were to play a tape of light’s behavior forward and then backward, you would see it behave in the same way moving in both directions in time. This is called time-reversal symmetry. And second, light, which can move through the world as a wave, has what is called polarization: how it oscillates relative to the motion of the wave. That polarization usually stays the same, providing another type of symmetry.

But inside this ring-shaped device, light both loses its time-reversal symmetry and changes its polarization. Inside the ring, light waves turn circles and resonate with one another, producing effects that don’t normally exist in the outside world. [The 10 Most Outrageous Military Experiments].

The brain-eating monsters are real enough — they lurk in freshwater ponds in much of the United States. Now scientists may have discovered a new way to kill them.

Minuscule silver particles coated with anti-seizure drugs one day may be adapted to halt Naegleria fowleri, an exceptionally lethal microbe that invades through the sinuses and feeds on human brain tissue.

The research, published in the journal Chemical Neuroscience, showed that repurposing seizure medicines and binding them to silver might kill the amoebae while sparing human cells. Scientists hope the findings will lay an early foundation for a quick cure.

Scientists say the microwave-sized craft would suck its watery fuel right out of the asteroids, planets and moons it’s exploring.

Fresh Air: Transplant Surgeon Joshua Mezrich On ‘When Death Becomes Life’ : Shots — Health News Joshua Mezrich has performed hundreds of kidney, liver and pancreas transplants. He shares stories from the operating room in his book, When Death Becomes Life.

Researchers at the University of Michigan have invented a new method of 3D printing which is up to 100 times faster than conventional existing 3D-printing processes. Here’s how it works, and why it could prove a game-changer for the way that 3D printing is currently used.

Yes, it’s a given that Google dominates the search market — but the fact is, Google is probably even more dominant than you would have guessed.

Amidst various sanctions by the United States, Russia might buy Bitcoins in the Billions as a way to mitigate these sanctions.

According to Vladislav Ginko who is a lecturer at the Russian Presidential Academy of National Economy and Public Administration, the Russian government which sits on $466 Billion of reserves is planning to invest heavily into Bitcoin. He told Micky that he believes the government could start investing Billions in Bitcoin as early as next month which could potentially trigger a bull run.

Psychiatrists diagnose people with schizophrenia, ADHD, bipolar disorder and other mental illnesses by spending time with them, looking for the particular behavior symptoms of each. What follows can be a hit-or-miss series of medications and dosages until disruptive behaviors go away.

By deciphering the circuitry of the medial frontal cortex — an area beneath the top of the head — those diagnoses could become much more efficient and precise by allowing physicians to diagnose based on how neurons respond to a simple series of behavior tests.

A Vanderbilt University team recently described how error and reward signals are organized within the cerebral cortex, which is only as thick as a nickel. They say this information could also be significant in drug development by guiding medications to target receptors in particular layers of the cerebral cortex where they will be most effective.
