SecurityWeek editor wiredmikey shares new that Jim Clark and Tom Jermoluk (past founders of Netscape, Silicon Graphics and @Home Network) “have launched a phone-resident personal certificate-based authentication and authorization solution that eliminates all passwords.” Security Week reports:
The technology used is not new, being based on X.509 certificates and SSL (invented by Netscape some 25 years ago and still the bedrock of…

Scientists predict state of matter that can conduct both electricity and energy perfectly
Three scientists from the University of Chicago have run the numbers, and they believe there may be a way to make a material that could conduct both electricity and energy with 100% efficiency—never losing any to heat or friction. …
Tim Sweeney: Android is a Fake Open System, and iOS is Worse
Epic Games CEO Tim Sweeney opened a game event in Las Vegas today with a call to make the industry more open and liberate it from the monopolistic practices of platform owners such as Google and Apple. From a report: In a talk about his vision for games in the next decade, Sweeney alternated between criticizing all of the big players…
Why Some Rope Knots Hold Better Than Others
Iwastheone shares a report from SciTechDaily: MIT mathematicians and engineers have developed a mathematical model that predicts how stable a knot is, based on several key properties, including the number of crossings involved and the direction in which the rope segments twist as the knot is pulled tight. “These subtle differences between knots critically determine whether a knot is strong or…

Boeing Fires CEO Dennis Muilenburg
McGruber writes: The Wall Street Journal is reporting that the Boeing Corporation fired its Chief Executive Officer Dennis Muilenburg (Warning: source paywalled; alternative source) as the company struggles to contain the fallout of its biggest crisis in decades, caused by two fatal crashes and the subsequent grounding of its 737 MAX jetliner. Boeing said David Calhoun, a longtime Boeing director with…
NASA Engineer’s ‘Helical Engine’ May Violate Laws of Physics
NASA engineer David Burns posted a paper describing the concept of his “helical engine,” which could take humans to the stars by exploiting mass-altering effects known to occur at near-light speed. Unfortunately, it’s been met with skepticism from those who say it violates the conservation of momentum, a core physical law. New Scientist explains: To get to grips with the principle…
How to control friction in topological insulators
Topological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists at the University of Basel and the Istanbul Technical University have begun investigating how they react to friction. Their experiment shows that the heat generated through friction is significantly lower than in conventional materials. This is due to a new quantum mechanism,…
