Submission + - Scientists At Fermilab Close In On Fifth Force of Nature (bbc.com)

Submitted by Anonymous Coward
An anonymous reader writes: Scientists near Chicago say they may be getting closer to discovering the existence of a new force of nature. They have found more evidence that sub-atomic particles, called muons, are not behaving in the way predicted by the current theory of sub-atomic physics. Scientists believe that an unknown force could be acting on the muons. More data will be needed to confirm these results, but if they are verified, it could mark the beginning of a revolution in physics.

All of the forces we experience every day can be reduced to just four categories: gravity, electromagnetism, the strong force and the weak force. These four fundamental forces govern how all the objects and particles in the Universe interact with each other. The findings have been made at a US particle accelerator facility called Fermilab. They build on results announced in 2021 in which the Fermilab team first suggested the possibility of a fifth force of nature. Since then, the research team has gathered more data and reduced the uncertainty of their measurements by a factor of two, according to Dr Brendan Casey, a senior scientist at Fermilab. "We're really probing new territory. We're determining the (measurements) at a better precision than it has ever been seen before."

In an experiment with the catchy name 'g minus two (g-2)' the researchers accelerate the sub-atomic particles called muons around a 50-foot-diameter ring, where they are circulated about 1,000 times at nearly the speed of light. The researchers found that they might be behaving in a way that can't be explained by the current theory, which is called the Standard Model, because of the influence of a new force of nature. Although the evidence is strong, the Fermilab team hasn't yet got conclusive proof. They had hoped to have it by now, but uncertainties in what the standard model says the amount of wobbling in muons should be, has increased, because of developments in theoretical physics. In essence, the goal posts have been moved for the experimental physicists. The researchers believe that they will have the data they need, and that the theoretical uncertainty will have narrowed in two years' time sufficiently for them to get their goal. That said, a rival team at Europe's Large Hadron Collider (LHC) are hoping to get there first.

Submission + - How Teen Hackers Exploited Security Weaknesses In World's Biggest Companies (cnn.com)

An anonymous reader writes: A group of teenage hackers managed to breach some of the world’s biggest tech firms last year by exploiting systemic security weaknesses in US telecom carriers and the business supply chain, a US government review of the incidents has found, in what is a cautionary tale for America’s critical infrastructure. The Department of Homeland Security-led review of the hacks, which was shared exclusively with CNN, determined US regulators should penalize telecom firms with lax security practices and Congress should consider funding programs to steer American youth away from cybercrime. The investigation of the hacks – which hit companies like Microsoft and Samsung – found that, in general, it was far too easy for the cybercriminals to intercept text messages that corporate employees use to log into systems. [...]

“It is highly concerning that a loose band of hackers, including a number of teenagers, was able to consistently break into the best-defended companies in the world,” Homeland Security Secretary Alejandro Mayorkas told CNN in an interview, adding: “We are seeing a rise in juvenile cybercrime.” After a series of high-profile cyberattacks marked his first four months in office, President Joe Biden established the DHS-led Cyber Safety Review Board in 2021 to study the root causes of major hacking incidents and inform policy on how to prevent the next big cyberattack. Staffed by senior US cybersecurity officials and executives at major technology firms like Google, the board does not have regulatory authority, but its recommendations could shape legislation in Congress and future directives from federal agencies. [...]

The board’s first review, released in July 2022, concluded that it could take a decade to eradicate a vulnerability in software used by thousands of corporations and government agencies worldwide. The second review, to be released Thursday, focused on a band of young criminal hackers based in the United Kingdom and Brazil that last year launched a series of attacks on Microsoft, Uber, Samsung and identity management firm Okta, among others. The audacious hacks were often followed by extortion demands and taunts by hackers who seemed to be out for publicity as much as they were for money. The hacking group, known as Lapsus$, alarmed US officials because they were able to embarrass major tech firms with robust security programs. “If richly resourced cybersecurity programs were so easily breached by a loosely organized threat actor group, which included several juveniles, how can organizations expect their programs to perform against well-resourced cybercrime syndicates and nation-state actors?” the Cyber Safety Review Board’s new report states.

When is gmail going to get an edit function? Maybe twitter actually needs draft tweets? Seems better than allowing to change the history of a conversation, no?

Seriously, if there's no edit but people are still clamouring for it, maybe a bit of education could go a long way helping them understand the difference between a blog and twitter. Oh, and reviewing up to 140 chars doesn't take that much effort.
