How live recordings of neural electricity could revolutionize how we see the brain

Posted by in category: neuroscience

Red and blue lights flash. A machine whirs like a distant swarm of bees. In a cubicle-sized room, Yoav Adam, a microscope, and a video projector capture something no one has ever seen before: neurons flashing in real time, in a walking, living creature.

For decades scientists have been searching for a way to watch a live broadcast of the brain. Neurons send and receive massive amounts of information—Toe itches! Fire hot! Garbage smells!—with impressive speed. Electrical signals can travel from cell to cell at up to 270 miles per hour.

But, neural electricity is just as hard to see as electricity in a telephone wire: To the unassisted eye, the busy brain looks as lifeless as rubber. So, to observe how neurons turn information (toe itches) into thoughts (“itching powder”), behaviors (scratching), and emotions (anger), we need to change the way we see.

Potentially Smallest Fusion Device Using Improved Z-Pinch Fusion

Posted by in category: nuclear energy

ARPA-E-funded alternative z-pinch fusion which is being developed by Zap Energy.

Zap Energy is the most compact solution to Fusion Energy and does not use complex and costly magnetic coils. They surpassed ARPA-E Alpha Milestones in August 2018. Their reactor is consistently producing neutrons and they received $6.8 million ARPA-E OPEN funding.

The new Z-pinch has the simplest geometry of any magnetic confinement configuration. It is a cylindrical plasma column.

NASA: Manufacturer’s Lies Caused Two Satellite Launches to Fail

Posted by in categories: government, satellites

The lies cost NASA more than $700 million and years of scientific work.


On Tuesday, NASA revealed that aluminum manufacturer Sapa Profiles, Inc. (SPI) “altered test results and provided false certifications” for materials used in the rockets, causing their fairings not to separate as designed.

“For nearly 20 years, Sapa Profiles and Sapa Extrusions [SPI’s corporate parent] falsified critical tests on the aluminum they sold — tests that their customers, including the U.S. government, depended on to ensure the reliability of the aluminum they purchased,” Assistant Attorney General Brian A. Benczkowski said in an April 23 statement.

Team develops system to legally test GPS spoofing vulnerabilities in automated vehicles

Posted by in categories: cybercrime/malcode, law, mobile phones, robotics/AI, satellites

Southwest Research Institute has developed a cyber security system to test for vulnerabilities in automated vehicles and other technologies that use GPS receivers for positioning, navigation and timing.

“This is a legal way for us to improve the cyber resilience of autonomous vehicles by demonstrating a transmission of spoofed or manipulated GPS signals to allow for analysis of system responses,” said Victor Murray, head of SwRI’s Cyber Physical Systems Group in the Intelligent Systems Division.

GPS spoofing is a malicious attack that broadcasts incorrect signals to deceive GPS receivers, while GPS manipulation modifies a real GPS signal. GPS satellites orbiting the Earth pinpoint physical locations of GPS receivers embedded in everything from smartphones to and aircraft. SwRI designed the new tool to meet United States federal regulations. Testing for GPS vulnerabilities in a mobile environment had previously been difficult because federal law prohibits over-the-air re-transmission of GPS signals without prior authorization.

Forever Battery a compelling talking point at CES

Posted by in category: futurism

Well, this lead was impressive, coming from a tech watcher who if you read his articles regularly know that he does not swoon easily. Andrew Liszewski, Gizmodo. “After covering CES for 10 years, nothing I’ve seen at the show has me as excited about the future as Ossia’s wireless charging technology.”

Ossia has worked on something they call the Cota Forever Battery. We need little explanation to turn heads to fuller attention. They have worked on a battery powered wirelessly. The Forever Battery and its associated technology, dubbed Cota, created much interest at CES.

It’s all about a battery that may never need replacing.
