Parents are buying these gadgets to protect their kids from school shooters

Posted by in category: education

Parents have been stocking up on bulletproof backpacks, tracking devices and doorstops… to give children a fighting chance at surviving a gunman’s attack at school,” the N.Y. Post reports:

“BulletBlocker, a company that sells bulletproof backpacks ranging in price from $199 for a girly pink one to $490, has seen sales jump 300 percent since the Florida shooting.”

A $95 metal device called “JustinKase,” which is placed under a door and latches to the door’s jamb to prevent entry, was invented by a 17-year-old Wisconsin high school student, Justin Rivard.

Millennials disrupted the system. Gen Z is here to fix the mess

Posted by in category: futurism

Plurals are known to value compromise, he said, a byproduct of their diversity and comfort with working with peers from different backgrounds. They are also in line to be an “adaptive” generation. These cohorts tend to come right after disruptive generations that change society in significant ways, such as millennials. When adaptive groups come of age, they take the problems that were brought to light by their predecessors and try to work them out.

In their organized calls for action, the students of Marjory Stoneman Douglas High School could be defining the nation’s newest generation.

Top A.I. experts warn of a ‘Black Mirror’-esque future with swarms of micro-drones and autonomous weapons

Posted by in categories: drones, robotics/AI

To better protect against the rise of ill-intended AI, policymakers ought to be working closely with technical specialists to be aware of potential applications of machine intelligence. Also, technical developers ought to be proactively reaching out to appropriate leaders when they understand the technology they are developing can have negative applications, the report says.

New report from 26 technology experts issues dire warning about the potential of malicious artificial intelligence.

Elon Musk Reveals Personal Crypto Holdings

Posted by in categories: bitcoin, cryptocurrencies, Elon Musk

Elon Musk has revealed his personal cryptocurrency holdings.

The billionaire CEO of SpaceX and Tesla told Twitter followers that he in fact has never purchased cryptocurrency, and only holds a small amount of Bitcoin gifted by a friend.

Not sure. I let @jack know, but it’s still going. I literally own zero cryptocurrency, apart from .25 BTC that a friend sent me many years ago.

Physicists Have Confirmed a Pear-Shaped Nucleus, And It Could Ruin Time Travel Forever

Posted by in categories: cosmology, physics, space travel, time travel

Physicists have confirmed the existence of a new form of atomic nuclei, and the fact that it’s not symmetrical challenges the fundamental theories of physics that explain our Universe.

But that’s not as bad as it sounds, because the 2016 discovery could help scientists solve one of the biggest mysteries in theoretical physics — where is all the dark matter? — and could also explain why travelling backwards in time might actually be impossible.

Tiny Light-Activated Gold-Covered Nanowires Can Make Neurons Fire

Posted by in categories: genetics, nanotechnology, neuroscience, solar power, sustainability

Researchers at the University of Chicago have developed light-activated nanowires that can stimulate neurons to fire when they are exposed to light. The researchers hope that the nanowires could help in understanding complex brain circuitry, and they may also be useful in treating brain disorders.

Optogenetics, which involves genetically modifying neurons so that they are sensitive to a light stimulus, has attracted a lot of attention as a research tool and potential therapeutic approach. However, some researchers have misgivings about optogenetics, as it involves inserting a gene into cells, potentially opening the door to unforeseen effects and possibly permanently altering treated cells.

In an effort to develop an alternative, a research team at the University of Chicago has devised a new modality that can enable light activation of neurons without the need for genetic modification. Their technique involves nanowires that are so small that if they were laid side-by-side, hundreds of them would fit on the edge of a sheet of paper. Although initially designed for use in solar cells, their small size also makes them well suited to interacting with cells.
