115 years ago, divers found a hunk of bronze off a Greek island. It changed our understanding of human history. One hundred fifteen years ago, an archeologist was sifting through objects found in the wreck of a 2,000-year-old vessel off the Greek island Antikythera. Among the wreck’s treasures — beautiful vases and pots, jewelry, a bronze statue of an ancient philosopher — was the most peculiar thing: a series of brass gears and dials mounted in a case the size of a mantel clock. Archeologists dubbed the instrument the Antikythera mechanism. The genius — and mystery — of this piece...

Care and feeding of Software Defined Radios We will cover the various kinds of antennas available to optimized your SDR radio for different types of spectrum monitoring. We will also explain why RF filters are necessary on most SDR's and when Low Noise Amplifiers help, and when Low Noise Amplifiers hurt reception.

NASA’s top executive concentrating on human spaceflight, Doug Loverro, has resigned just a week before the scheduled start of a milestone space mission. Loverro became NASA’s associate administrator for human exploration and operations last December, and was playing a leading role in NASA’s Artemis moon program as well as preparations for next week’s launch of a SpaceX Crew Dragon mission to the International Space Station. That mission, set for liftoff on May 27 from NASA’s Kennedy Space Center in Florida, is due to send NASA astronauts Doug Hurley and Bob Behnken to the station for a stay that could last...

Capella Space announced May 13 that it signed a deal to provide synthetic aperture radar to the U.S. Navy, even though the company has yet to put a satellite on orbit. SAR creates images with radar, meaning it can produce images regardless of the weather or lighting conditions. SAR satellite constellation will be able to collect sub-0.5 meter imagery, capable of identifying various types of aircraft or vehicles at ground level.

Commerce Secretary Wilbur Ross has been in discussions for several years with both TSMC and Intel to build advanced chip manufacturing plants in the U.S. and extract U.S. supply chain needs from China and southeast Asia. It appears his efforts, and the emphasis on global supply-chain shifts from President Trump, are getting results. According to numerous media reports Taiwan Semiconductor Manufacturing Co (TSMC) is likely to announce this week they will build an advanced chip manufacturing facility in Arizona. A manufacturing facility for advanced 5 nanometer chip manufacturing is a steep investment decision costing around $10 billion. This shift in...

CHARLES TOWN, W.Va. — Regardless of where the Eastern Panhandle stands with COVID-19 this fall, Jefferson County students will have a choice of how they attend school. During Monday night’s regular meeting, Superintendent Dr. Bondy Shay Gibson said the school system is continuously updating its technological infrastructure. Students will have the option of full virtual learning.

It is a risky bet for US President Donald Trump’s administration to push for building advanced semiconductor factories in the US due to growing fears about the US’ heavy reliance on Asia for chip supply and potential disruptions from uncontrollable factors such as the COVID-19 pandemic. The US government is in discussions with chipmakers, including Taiwan Semiconductor Manufacturing Co (TSMC), to build new fabs in the US to create a self-sufficiency in chips, the latest in a slew of Trump’s renewed “Make in the US” efforts, the Wall Street Journal reported on Sunday. Even before the pandemic, the US had...

That is interesting, but does not surprise me.

With the current coronavirus crisis creating a boom for video meetings, competition for secure platforms has become fierce. The recent controversies surrounding early frontrunner Zoom allowed Google to pounce at the opportunity, making rival Google Meet free to the general public. Google has begun positioning itself as the pro-privacy option because of supposed protections it has in place, even as many in the public remain skeptical. No protections in the world, however, will change that Google is a corporation whose whole business model revolves around tracking, mining, and selling personal user data, along with the history of privacy violations that...

I need a surge protector good one. Considering a UPS/surge but dont think I need one but maybe I wont hurt. I will be putting my iMac on it and the cable companies data modem. All I get from them is internet. CATV guy told me dont put the Coax through it it will blow the data out of the water.Just the 110 AC power side Curious what some of you would recommend in regard to Mfg and Juoles or what ever they are called? UPS/surge VA/Watts. I am in a wicked summer lightning area. These are the specs for...

Facial recognition systems threaten our privacy. They can track where you go and add that information to the massive amount of information already saved about each of us. Big Brother is watching you and enabled by AI. And when it makes a mistake reading your face, you could end up with criminal charges far worse than when the toll tag system misreads your license plate. Here are several methods for fooling and interfering with facial recognition systems.

Martensite steel powder used for 3D printing. Inset shows a zoomed-in view of the steel powder. Credit: Raiyan Seede/Texas A&M University College of Engineering For millennia, metallurgists have been meticulously tweaking the ingredients of steel to enhance its properties. As a result, several variants of steel exist today; but one type, called martensitic steel, stands out from its steel cousins as stronger and more cost-effective to produce. Hence, martensitic steels naturally lend themselves to applications in the aerospace, automotive and defense industries, among others, where high-strength, lightweight parts need to be manufactured without boosting the cost. However, for these and...

Professor Charles Lieber’s arrest on Jan. 28 made headlines on all the major U.S. media. After all, he was not only a Harvard professor, he was a world-class researcher in nanotechnology, working on highly sensitive research projects for the U.S. government. The FBI complaint alleges that he had been secretly participating in China’s “Thousand Talents Plan” since 2011, paid some $600,000 a year plus expenses to open and operate a lab at the Wuhan University of Technology (yes, that Wuhan). We know that China contracts with American experts in this way in order to steal their research and gain commercial...

Technology bolsters US dominance of the list, but coronavirus fallout looms largeThe inaugural FT Americas ranking comes at a perilous and uncertain time for many companies, as the coronavirus severely curtails economies, workforces and ultimately growth. Yet the ranking also highlights 500 businesses across the continent for whom innovation and creativity have paid off — attributes that will underpin resilience and enable many of them to thrive once the worst effects of the pandemic are behind them. The FT list was compiled with Statista, a research company, and ranks entrants from across the Americas by compound annual growth rate (CAGR)...

Editor's Note: This piece was authored by Young Voices contributor James Czerniawski. The coronavirus pandemic has certainly thrown the world for a loop. Governments are at a loss on how to effectively address the issue, making policy decisions like statewide shutdowns that send local economies into a tailspin. This isn’t a surprise, since the government is pretty prone to mishandling crises.  But the good news is that the private sector is stepping into the gap. Technology companies, for instance, have been playing an increasingly important role in responding to crises. The government can help—by getting out of their way. One of the...

Relocatable mobile surveillance towers that can be mounted on the backs of pickups are the latest high-tech innovation that Border Patrol agents are looking to help them patrol the Southwest border, agency officials said. Border Patrol touted these compact towers as the singular piece of equipment they (most) want to deploy on the border... “Reliable imaging can be relocated very rapidly and useful in rural terrain.”... Bobby Brown, senior director for customs border direction for Elbit Systems of America... says the mobile towers can be up and running in four minutes and have multiple cameras and radar that can “see”...

Lithium is expensive, environmentally questionable in large volumes, and tends to catch on fire from time to time. It's the best solution we've currently got for EV and device battery storage, but other alternatives are starting to surface, and one that could actually make a fair bit of sense is the potassium metal battery.
