Elon Musk tells Twitter staff about possible bankruptcy, top executives leave

Posted by in category: Elon Musk

Twitter might attract FTC fines for non-compliance.

The world’s richest person Elon Musk has warned staff at this newly acquired social media company that bankruptcy was very much a possibility at Twitter. The result has been an exodus of top executives at the company, The Guardian.

Nearly two weeks after finally agreeing to acquire Twitter, Musk held an all-hands meeting at the company and once again spoke about the amount of money the company was losing. According to The Information, Musk warned that the current cash outflow rate at the company would lead to a negative balance of billions of dollars by 2023. His idea of Twitter Blue subscriptions was the only way to keep the company alive.

Machine learning of binary ‘yes/no’ systems may improve medical diagnoses, financial risk analysis, and more

Posted by in categories: biotech/medical, finance, robotics/AI

Similar to a mouse racing through a maze, making “yes” or “no” decisions at every intersection, researchers have developed a way for machines to swiftly learn all the twists and turns in a complex data system.

“Our method may help improve the diagnosis of urinary diseases, the imaging of cardiac conditions and analysis of financial risks,” reported Abd-AlRahman Rasheed AlMomani of Embry-Riddle Aeronautical University’s Prescott, Arizona, campus.

The research was accepted for the Nov. 11 edition of the journal Patterns with Jie Sun and Erik Bollt of Clarkson University’s Center for Complex Systems Science. The goal of the work is to more efficiently analyze binary (“Boolean”) data.

The mathematics that makes us realize we don’t know much: Behavior of spin glasses

Posted by in categories: economics, mathematics, physics, robotics/AI

Spin glasses are alloys formed by noble metals in which a small amount of iron is dissolved. Although they do not exist in nature and have few applications, they have nevertheless been the focus of interest of statistical physicists for some 50 years. Studies of spin glasses were crucial for Giorgio Parisi’s 2021 Nobel Prize in Physics.

The scientific interest of spin glasses lies in the fact that they are an example of a complex system whose elements interact with each other in a way that is sometimes cooperative and sometimes adversarial. The mathematics developed to understand their behavior can be applied to problems arising in a variety of disciplines, from ecology to machine learning, not to mention economics.

Spin glasses are , that is, systems in which individual elements, the spins, behave like small magnets. Their peculiarity is the co-presence of ferromagnetic-type bonds, which tend to align the spins, with antiferromagnetic-type bonds, which tend to orient them in opposite directions.

SpaceX shakes up Starship leadership in Texas as push for the rocket’s next milestone intensifies

Posted by in categories: Elon Musk, space travel

Elon feels that Starship is moving too slow so he is now throwing a lot more resources at it.


While Elon Musk earns daily headlines over changes at Twitter, a significant reorganization is underway at his space company’s Texas launch facility.

SpaceX president and COO Gwynne Shotwell and vice president Mark Juncosa – two of the most influential executives at the company aside from Musk himself – are now overseeing the facility and operations of the company’s Starbase location, people familiar with the situation told CNBC.

Zuckerberg Wants Facebook to Build a Mind-Reading Machine

Posted by in categories: computing, transportation

Zuckerberg likes to quote Steve Jobs’ description of computers as “bicycles for the mind.” I can imagine him thinking, “What’s wrong with helping us pedal a little faster?”

And while I reflexively gag at Zuckerberg’s thinking, that isn’t meant to discount its potential to do great things or to think that holding it off will be easy or necessarily desirable. But at a minimum, we should demand a pause to ask hard questions about such barrier-breaking technologies—each quietly in our own heads, I should hasten to add, and then later as a society.

Our Universe Trailer: Morgan Freeman Narrates The History Of Everything

Posted by in categories: education, space

When you need someone to narrate the history of the universe — and Mel Brooks is busy — you might as well go with Morgan Freeman. Not only has Freeman played God in “Bruce Almighty” and “Evan Almighty,” but he’s also told “The Story of God” and “The Story of Us” for National Geographic.

In “Our Universe,” Freeman is lending his voice to a new six-part nature documentary series for Netflix. As the title implies, this series is even bigger in scope than “The Story of Us.” It’s looking back at the whole history of the universe and how 13.8 billion years have led us to this moment.

US observed Russian navy preparing for possible test of nuclear-powered torpedo

Posted by in categories: military, nuclear energy, robotics/AI

The US observed Russian naval vessels preparing for a possible test of a new nuclear-powered torpedo in recent weeks, a senior US official with direct knowledge told CNN.

Among the vessels which took part in the preparations was the Belgorod, a cruise missile submarine modified for special operations that is able to launch unmanned underwater vehicles including the Poseidon torpedo.

In the last week, the vessels were observed leaving the testing area in the Arctic Sea and heading back to port without carrying out a test. The US believes the Russians may have encountered technical difficulties.

Vertical Axis Wind Turbines Are Heading Out To Sea

Posted by in category: sustainability

Vertical axis turbines missed their moment in the 1980s, but they are back, and they are getting bigger. That may come as a surprise. The technology was confined to niche applications and all but written off just a few years ago. Now they are poised for a new growth spurt in the rooftop field, and they are even heading out to sea.

The Long Road To Vertical Axis Wind Turbines

For those of you new to the topic, vertical axis wind turbines are engineered to make curved blades rotate around a central, upright pole. The US Department of Energy’s Sandia National Laboratory was experimenting with a scaled up design that resembled an egg beater back in the 1980s, as depicted in the photo at the top of this article.
