Scientists produce tokamak plasma that’s stable at 10x Greenwald limit. Future reactor-scale tokamaks will likely need to operate near or above the Greenwald limit. Physicists from the University of Wisconsin–Madison have developed a tokamak plasma that is stable at ten times the Greenwald limit. Their achievement has implications for tokamak fusion reactors, but scientists caution … Read more
A developer created a Windows XP mod without Internet Explorer’s core components. The mod runs basic apps like Calculator successfully, but not those reliant on IE components. It gives a classic Windows feel with an NT 4.0 Explorer replacement. Windows XP was highly rated when launched in 2001, but Microsoft faced criticism for deeply integrating … Read more
When it comes to DNA replication, humans and baker’s yeast are more alike than different, scientists discover. They found that a molecular complex called CTF18-RFC in humans and Ctf18-RFC in yeast loads a “clamp” onto DNA to keep the replication machinery from falling off the DNA strand. This mechanism is crucial for accurate DNA copying. … Read more
How Søren Kierkegaard’s View of Hindsight Can Help Us Reframe Our Work-Lives Søren Kierkegaard once wrote, “Life can only be understood backwards… but it must be lived forwards.” This quote highlights the paradox that life is a journey we must live forward while trying to understand and learn from the past. In our daily lives, … Read more
Layered superconductor coaxed to show unusual properties with potential for quantum computing A team led by researchers from the California NanoSystems Institute at UCLA has designed a unique material based on a conventional superconductor. The experimental material showed properties signaling its potential for use in quantum computing, a developing technology with capabilities beyond those of … Read more
[SMS Blasters — which are also known as Stingrays, False Base Stations (FBS), and cell-site simulators — can be used by nefarious parties to “lure mobile devices to connect to them” and send fake text messages. One way to combat them is by disabling the insecure 2G connection on your Android device. GSMA’s Fraud and … Read more
CrowdStrike is being sued by its shareholders over a faulty software update that caused a global IT outage, affecting more than eight million computers. The lawsuit claims the company made “false and misleading” statements about its software testing. The suit alleges that CrowdStrike executives defrauded investors by making them believe the company’s software updates were … Read more
The mood on Wall Street is changing. Traders previously expected the Federal Reserve to cut interest rates in September, but now there’s concern that the Fed might not act quickly enough to keep the job market strong. This uncertainty has led to a stock market reset, with major indexes like the Dow, S&P 500, and … Read more
A higher-dimensional model can help explain cosmic acceleration without dark energy. Dark energy remains a puzzle in our understanding of the cosmos. The standard model of cosmology, Lambda-CDM, accounts for it by adding a constant term to Einstein’s field equation. This constant is very small and positive but lacks a complete theoretical understanding. Physicists look … Read more
NASA’s Mars rover finds evidence of potential fossilized life on the Red Planet A peculiar leopard- spotted rock found near an ancient riverbed in Mars’ Jezero crater contains clues of ancient life, NASA said. The rock, nicknamed Chevaya Falls, has signs of chemistry that could have supported ancient microbes. The Perseverance rover discovered the rock … Read more
