The disc of material swirling around a supermassive black hole may give birth to many planetsNASA and M. Weiss/Chandra X-ray Center The active centres of galaxies might be regions of extraordinary planet formation, where millions of worlds are born. Most galaxies in the universe, such as our own Milky Way, host a supermassive black hole at their centre. Most of the time, these black holes are quiescent, as there is no matter falling into them. But occasionally they become active and consume huge amounts of dust and gas, perhaps from a merger with another galaxy, becoming an active galactic nucleus…

More Information A stable frequency source is a fundamental requirement in virtually every RF and wireless system, yet all real-world oscillators exhibit some degree of short-term frequency instability known as phase noise. This instability manifests as unwanted sidebands around the carrier in the frequency domain and as timing jitter in the time domain. When phase noise is excessive, it causes spectral regrowth that leaks energy into adjacent channels, reduces receiver sensitivity through reciprocal mixing, and rotates digital modulation constellations to the point where bit errors multiply. Understanding these effects is essential for engineers designing transmitters, receivers, and frequency synthesizers for…
For decades, Switzerland sold one thing better than perhaps any country on earth: privacy. That became its true export. People think of watches, chocolate, pharmaceuticals, or skiing resorts, but Switzerland’s real business was protecting capital from governments. That was the foundation of modern offshore banking. Switzerland has destroyed the very industry that made it rich. Hong Kong has officially overtaken Switzerland as the world’s largest offshore wealth hub, managing roughly $2.95 trillion in cross-border wealth compared to Switzerland’s $2.94 trillion, according to the latest Boston Consulting Group report. This was entirely self-inflicted. I warned years ago that Switzerland was committing…

MEGA On May 19, Harry and Meghan took a trip down memory lane as they celebrated their wedding anniversary on social media by…
The IISS report examined issues including how military doctrines shape the way armed forces prepare for warfare, the modernisation of Asian militaries, nuclear competition, the rise of quantum technology, key Indian Ocean chokepoints, and the challenges Thailand faces in responding to Myanmar’s post-coup conflict. Military doctrines still framed by historical rifts are creating new security challenges, said the report.These influence how countries prepare for war and can ultimately heighten tensions, cautioned Laksmana, who leads the IISS’ Southeast Asian security and defence research programme.”A military doctrine can almost become a self-fulfilling prophecy, because the idea is that you train how you want…
Iran has said it used a new air defence system to shoot down a United States MQ-9 Reaper drone near the Strait of Hormuz earlier this week, an incident analysts say shows that Tehran has retained its capacity to repel US and Israeli attacks despite months of strikes on its military sites.Iranian media said the drone was brought down near Qeshm Island in the Strait of Hormuz, adding that the interception marked the first combat use of a locally developed system called Arash-e Kamangir.Recommended Stories list of 4 itemsend of listThere has been no independent corroboration of Iran’s claim of…
NFL insider Albert Breer of Sports Illustrated and former New England Patriots defensive back Jason McCourty are among those who have said that the Patriots acquiring Philadelphia Eagles wide receiver A.J. Brown is “almost a done deal.” On Wednesday, Breer addressed what the Patriots will have to give up for Brown via the transaction that can’t become official before June 1 due to reasons related to the salary cap.A team “other than the Patriots” discussed sending this to the Eagles for A.J. Brown”I still believe the throughway to satisfying the Eagles’ desire for a first-round pick is pushing that return into 2028,” Breer wrote. “Philadelphia…
What’s your understanding of the constraints on what the Pentagon allows a drone or an autonomous weapon to do without a human deciding, “Kill this person, shoot this person”? The more important thing is what it doesn’t say. It doesn’t say you’re not allowed to automate the kill chain. So you’re allowed to do that? You are not not allowed to do that. Right. Chris Brose, welcome to “Interesting Times.” Thank you. Great to be here. So it seems to me like the future of high-tech warfare has arrived, that we are living through a revolution in warfighting unlike any…

“Universal” biological signatures of aging shared across different mammalian species—including humans—could offer new clues to identifying longevity and antiaging treatments or interventions, a new study finds.Age isn’t just the number of candles on a cake. That’s a representation of your chronological age, while your “biological age” is a measure of how your body’s various tissues and cells are holding up over time—and the two don’t necessarily match. Instead your biological age may be higher or lower than your chronological age for several reasons, such as your lifestyle choices, a chronic disease if you have one, your genes, and more. Researchers…
