Scientists may have discovered the most powerful particle collider in the universe

Supernovas can become some of the most powerful particle colliders in the universe — but only if they pass a whole lot of gas before they explode, new research finds. For almost a century, astronomers have detected high-energy particles streaming in from the distant universe. Known as cosmic rays, they are made primarily of protons and, occasionally, nuclei of heavier elements. Most cosmic rays are deflected by Earth's magnetic field or are absorbed in the upper atmosphere, but some make it all the way to the surface. Roughly once every second, a cosmic ray manages to strike your body. The cosmic rays span a broad range of energies, with the most powerful ones topping one peta-electron volt (PeV). That's one quadrillion electron volts, or up to a thousand times more powerful than the collision energies of the Large Hadron Collider, the world's most powerful atom smasher. Astronomers have long suspected that the explosive deaths of massive stars may be responsible for these extremely powerful cosmic rays. After all, these supernovas have all the right ingredients: There is a detonation with more than enough energy, a flood of elementary particles, and magnetic fields that can drive those particles into a frenzy before releasing them into the cosmos. But observations of nearby supernova remnants such as Tycho and Cassiopeia A have not met expectations; the cosmic rays coming from those places are far weaker than expected. In a paper accepted for publication in the journal Astronomy & Astrophysics, researchers have rescued the supernova hypothesis and found that, in special cases, supernova remnants are indeed capable of becoming "PeVatrons" — that is, explosions capable of generating PeV cosmic rays. Related: World's largest atom smasher turned lead into gold — and then destroyed it in an instant The team found that, before going supernova, a star must lose a significant amount of mass — at least two suns' worth of material. This is fairly common, as powerful winds can drive off the outer layers of a star's atmosphere prior to the main explosion. But crucially, that material can't disperse too widely. It has to stay dense, compact and close to the star. Then, when the supernova finally happens, the shock wave from the exploding star slams into this shell of material. And then all hell breaks loose.

As the shock travels through the surrounding shell, magnetic fields ramp up to incredibly powerful energies. These magnetic fields take any random subatomic particles — the debris in the shell — and accelerate them, bouncing them back and forth within the shock wave. With every bounce, the particle gains more energy. Finally, it gets enough energy to leave the chaos altogether and stream into the universe. But within a few months, the system loses steam as the shock wave slows down. It still produces abundant cosmic rays, but not above the PeV threshold. This scenario explains why we haven't directly observed any active PeVatrons. Even though a supernova goes off in the Milky Way every few years, none have been close enough in modern times for us to observe the short window when they can accelerate cosmic rays to these extreme energies. So we'll just have to be patient.

Blockchain-based HUMO token backed by government bonds to be piloted in Uzbekistan
TASHKENT, Uzbekistan, May 13, 2025 (GLOBE NEWSWIRE) -- Uzbekistan is set to pilot a new asset-backed token, HUMO, tied to government bonds. The project aims to create innovative methods of attracting foreign investment, increase transparency of financial transactions, and establish an even more attractive investment environment. The HUMO token will be backed by government bonds. This structure is intended to provide price stability while minimizing speculative volatility – often a key concern for tokenized instruments. It should be noted that the project fully complies with the legislative requirements of the Republic of Uzbekistan regarding the circulation of crypto assets. Institutional anchors and technical foundations The project is being developed with support from several domestic and international partners. HUMO, the payment system serving over 35 million cardholders and widely integrated into the country's banking and retail sectors, will serve as the foundation of the project. HUMO's vast integration with banks and merchants naturally sets the token for mass adoption. Technical development is spreadheaded by Asterium, a local crypto service provider, and Broxus, blockchain infrastructure vendor. The project is planned to be launched based on two technologies – EVM and TVM. The technological foundation chosen for TVM is Tycho, a protocol that will ensure support for high loads, scalability, and cost-effective transactions. Tycho is built to support high throughput and low transaction costs, which is critical for potential government-scale use cases. Token benefits: Transparency, cost reduction, and integration The HUMO token aims to facilitate instant payments, reduce transaction fees, and improve transparency by recording operations on a public blockchain. According to project headliners, it may also help limit informal financial flows and improve the efficiency of cashless payments. Alexey Maksimov, Chairman of HUMO, noted that the launch of the HUMO-backed token is an important step towards building an innovative and modern financial system in Uzbekistan: 'The creation of this token, fully backed by real assets, will help increase public trust, simplify transactions, and accelerate the development of the country's digital economy. One of our key objectives is to enhance transparency and reduce the risk of fraud, which is especially important in the current environment.' Komilkhuzha Sultonov, Director of Asterium, described the initiative as a step towards integrating blockchain into everyday financial processes: 'The HUMO token project lays the groundwork for a new financial system. We are creating a solid infrastructure that integrates modern technology into daily financial transactions, making interactions with crypto assets as simple and routine as it would be with traditional assets.' Broxus founder Sergey Shashev emphasized the importance of scalable and secure infrastructure: 'We're delighted to see Broxus technologies contributing to a project of such significance for the government. Our mission is to deliver solutions that make digital transactions safe, accessible and transparent, and the Tycho blockchain can achieve that while maintaining high transaction speeds, low fees and reliability required by projects at this level.' Looking ahead With linkage to real-world assets, the HUMO token may serve as a ground for broader blockchain integration into Uzbekistan's financial system. In the future, the blockchain platform created within this project could serve as a basis for the development of new digital services in Uzbekistan. About HUMO National Interbank Processing Center of Uzbekistan (national payment system HUMO) is one of the leading financial infrastructures of Uzbekistan. Its main goal is to become a key financial hub not only in Central Asia but also beyond its borders. Since its inception, HUMO has demonstrated steady growth, actively expanding its payment services ecosystem and strengthening partnerships both domestically and internationally.

See Sacramento band Tycho play Channel 24 in new venue's debut weekend
Midtown music venue Channel 24 welcomed new patrons and hometown band Tycho as its opening weekend continued on Friday. Tycho frontman Scott Hansen, who grew up in the Sacramento region before relocating to San Francisco, collaborates on his group's electronic melodies with guitarist Zac Brown, a Sacramento resident, drummer Rory O'Connor and multi-instrumentalist Billy Kim. 'This is just such a special moment for us,' said Hansen about playing in front of friends and family in his hometown at the new venue. Hansen said that his former home provided inspiration for his music. Tycho has twice been nominated for a Grammy for best dance/electronic album. 'I feel like all the energy of this music is about the river and the fields all around here,' he said. Channel 24 welcomed country music singer Tucker Wetmore on Thursday for its first show. Its opening weekend concludes Sunday with roots singer Sierra Ferrell.
