Don't Miss These Insightful Museums in Chiang Rai – Discovering a Rich Thai Heritage
This museum is the perfect starting point before you set off on a trek to meet Chiang Rai's hill tribes. Run by the Population and Community Development Association, it shines a light on the six main tribal groups of Northern Thailand: Hmong, Lahu, Akha, Karen, Yao, and Lisu. After a short but insightful slide show, you can wander around looking at displays of traditional clothing, harvest tools, bamboo items, and more. It's kind of like being handed a guidebook to the region's living cultures. Plus, the small souvenir shop here sells authentic handmade items, so you can take a meaningful piece of the experience home with you.

Hungry Black Hole Rips Apart And Swallows 'Hapless' Star 600 Million Light-Years Away
In a scene straight out of a sci-fi movie, scientists have captured a hungry black hole that is ripping up and gobbling a star that came in its wake. The tidal disruption event (TDE) took place 600 million light-years away and was caught by the Hubble Space Telescope, showing a spectacular burst of radiation after the black hole was done swallowing the 'hapless' star. As per NASA, out of around 100 TDE events recorded so far, this is the first time that an offset TDE has been identified. The one million-solar-mass black hole is not exactly in the centre of its host galaxy, where supermassive black holes are typically found consuming the surrounding material. 'AT2024tvd is the first offset TDE captured by optical sky surveys, and it opens up the entire possibility of uncovering this elusive population of wandering black holes with future sky surveys,' lead study author Yuhan Yao of the University of California at Berkeley said. Notably, a TDE happens when an infalling star is stretched or "spaghettified" by a black hole's immense gravitational tidal forces. A black hole revealed itself from 600 million light-years away when it ripped apart and swallowed a star. The resulting burst of radiation is the bright dot just off-center captured in this @NASAHubble image. — NASA (@NASA) May 8, 2025 Supermassive black hole lurking nearby What makes the finding more astonishing is the fact that it took place only 2,600 light-years from the more massive black hole at the galaxy's centre. That's just one-tenth the distance between our Sun and the Milky Way's central supermassive black hole. Strangely, the two supermassive black holes co-exist in the same galaxy, but are not gravitationally bound to each other as a binary pair. "The smaller black hole may eventually spiral into the galaxy's centre to merge with the bigger black hole. But for now, it is too far separated to be gravitationally bound," NASA stated. As for why the black hole had got off-centre, scientists theorised that the three-body problem might be the reason for its odd geography. . 'If the black hole went through a triple interaction with two other black holes in the galaxy's core, it can still remain bound to the galaxy, orbiting around the central region,' said Mr Yao. This is not the first time when a black hole has been spotted consuming a neighbouring or wayward star. In November last year, scientists discovered a black hole, named LID-568, devouring matter at a phenomenal rate -- over 40 times the theoretical limit, called the Eddington limit.

Manchester man arrested after pre-dawn gunfire incident
City police arrested a Manchester man early Wednesday after officers heard gunshots and found him allegedly attempting to flee the scene with multiple weapons. Stephen Yao, 35, faces charges of reckless conduct and criminal threatening following the incident in downtown Manchester. About 2:50 a.m. Wednesday morning, a police officer near the intersection of Chestnut and Concord streets reported hearing gunshots, which was confirmed by the department's ShotSpotter detection system. Responding officers observed a man, later identified as Yao, holding a rifle while entering a vehicle. Police said Yao, who also had a pistol holstered on his hip, initially refused officers' commands to exit the vehicle before eventually complying and being taken into custody without incident. Investigators determined Yao had fired multiple shots outside a Pine Street residence, police said. No injuries or property damage were reported. Police did not immediately release information about a possible motive or when Yao would appear in court.

Physicists Capture First-Ever Images of Free-Range Atoms

Yahoo is using AI to generate takeaways from this article. This means the info may not always match what's in the article. Reporting mistakes helps us improve the experience. Generate Key Takeaways Free-range atoms, roaming around without restrictions, have been captured on camera for the first time – enabling physicists to take a closer look at long predicted quantum phenomena. It's a bit like snapping a shot of a rare bird in your back garden, after a long time of only ever hearing reports of them in the area, and seeing the food in your bird feeder diminish each day. Instead of birdwatching, though, we're talking about quantum physics. The US researchers behind the breakthrough carefully constructed an "atom-resolved microscopy" camera system that first puts atoms in a contained cloud, where they roam freely. Then, laser light freezes the atoms in position to record them. The team was able to freeze atoms in place to take a snapshot of them. (Yao et al., Phys. Rev. Lett., 2025) "We are able to see single atoms in these interesting clouds of atoms and what they are doing in relation to each other, which is beautiful," says physicist Martin Zwierlein, from the Massachusetts Institute of Technology (MIT). Being able to capture these atoms as they interact means new opportunities to study matter at the smallest of scales, in the quantum realm – and the researchers have already taken a closer look at several rare atom patterns. These patterns include a state known as Bose-Einstein condensation – made up of bosons, and fermions as they pair up. It all adds to our understanding of how incredibly tiny atoms behave and change in their behavior. As another example, the team was able to directly capture an image of a 'de Broglie wave', named after French physicist Louis de Broglie, in which bosons bunch together. This theory is partly responsible for the beginnings of modern-day physics. While these scenarios have been studied before, now they can be analyzed in more detail, giving scientists the opportunity to take measurements and make observations not previously possible – right down to individual atoms. "[Existing] techniques allow you to see the overall shape and structure of a cloud of atoms, but not the individual atoms themselves," says Zwierlein. "It's like seeing a cloud in the sky, but not the individual water molecules that make up the cloud." Trying to track and monitor atoms is incredibly tricky. These particles are just a tenth of a nanometer in size – that's about a millionth of the width of a human hair – which is why these complex imaging setups are required. Now that the researchers behind the new approach have shown it can work, they want to use it to investigate other types of atom interactions and behaviors. Of particular interest are the rarest and least studied scenarios, with quantum Hall physics – where electrons have unusual interactions with magnetic fields – on the shortlist. "When you see pictures like these, it's showing in a photograph, an object that was discovered in the mathematical world," says MIT physicist Richard Fletcher. "So it's a very nice reminder that physics is about physical things. It's real." The research has been published in Physical Review Letters. Related News

Strategists optimistic on China even as US-China trade war climbdown looks far off
As financial markets pin their hopes on a de-escalation in the US-China trade war, some experts caution that meaningful progress in striking a deal between the world's two largest economies may still be some way off. "Either tariffs are cut to more palatable levels or both sides put more exclusions on the table to make tariffs effectively less binding," Aidan Yao, Amundi's senior investment strategist for Asia, told the Reuters Global Markets Forum. "For now, signs of these are sparse, presumably because the pain threshold has not been reached," Yao said, adding that the outlook for the Chinese economy still looks positive. China recently said it was "evaluating" a US proposal to resume trade talks over Washington's 145 per cent tariffs. It has also created a list of US-made products for exemption from its 125 per cent retaliatory tariffs. Sat Duhra, portfolio manager at Janus Henderson, said, "Trump will need to respond if the threat of a recession increases significantly, which the equity market, dollar and the Treasuries arguably are beginning to point to." He said a resolution would benefit his company's positioning in China. Duhra has been lapping up Chinese stocks, noting opportunities in banks, technology and sportswear among other sectors, citing higher dividends and lower valuations. While Janus Henderson is broadly "neutral weight" on Chinese equities, Amundi holds a close to "neutral" stance, preferring domestic-oriented sectors in A-shares and AI-leading tech names in offshore stocks. China's blue-chip CSI300 and Shanghai Composite are down 4 per cent and 2 per cent year-to-date, respectively, in line with their US counterparts - S&P 500 and Nasdaq down 3 per cent and 7 per cent, respectively.
