Evolution of Hot Jupiters: From Cold Giants to Star-Hugging Worlds

Posted by in categories: computing, space

“This new planet supports the theory that high eccentricity migration should account for some fraction of hot Jupiters,” said Dr. Sarah Millholland.


How do exoplanets evolve throughout their lifetimes, specifically those known as “hot Jupiters”, which have been found to orbit extremely close to their parent stars? This is what a recent study published in Nature hopes to address as an international team of researchers investigated the highly eccentric orbit of TIC 241,249,530 b, which is a Jupiter-sized exoplanet located approximately 1,100 light-years from Earth. This study holds the potential to help astronomers better understand the formation of exoplanets like hot Jupiters and how their orbits evolve over time.

Now, TIC 241,249,530 b could help astronomers piece together the evolution of hot Jupiters given the exoplanet’s highly eccentric orbit, meaning it travels very close to its parent star at certain points followed by swinging back out to well beyond the parent star, completing one orbit in 167 days. Astronomers hypothesize this could mean that hot Jupiters initially begin as cold Jupiters in highly eccentric orbits only to slowly become more circular and closer to its parent star over time.

Huawei’s long-awaited Windows challenger will likely come to PCs this year — HarmonyOS Next makes the transition from phones to desktops and laptops

Posted by in categories: computing, mobile phones

HarmonyOS Next, on the other hand, is an Android-free variant of HarmonyOS. The new operating system doesn’t use AOSP libraries, can’t run.apk files, and is a significant step towards complete independence from US-based software for the vendor. HarmonyOS Next is not currently shipping with Huawei products but is available as a developer sandbox to develop and test apps for native HarmonyOS use. HarmonyOS Next hasn’t yet arrived on PC, but recent leaks suggest it soon will, paving the way for a new Chinese homegrown desktop OS.

Images of HarmonyOS Next for PC suggest an operating system taking design cues from MacOS. The system has a familiar status bar and dock bar combo on the top and bottom. The fullscreen/minimize/close buttons live on the right-hand side of programs, mirroring MacOS’s traffic light system.

Huawei’s recent strategy for HarmonyOS has publicly been phones-first. With HarmonyOS being open-source, much like Android, widespread adoption across the Chinese market and beyond outside of Huawei phones is possible and a big goal for Huawei. HarmonyOS already makes up 16% of the Chinese phone market, which is expected to grow in the coming years.

Digital archaeology: New LEP data now available to all

Posted by in categories: computing, futurism

Unlike letters carved on the Rosetta stone, digital data is not written on a virtually immutable support. Just a few years after it is written, its format becomes obsolete, the readout analysis tools can’t run on computers and the visualization code no longer works. But data can still contain interesting scientific information that should remain available to future generations of scientists.

Metamaterials for the data highway: New concept offers potential for more efficient data storage

Posted by in categories: computing, transportation

Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), TU Chemnitz, TU Dresden and Forschungszentrum Jülich have been the first to demonstrate that not just individual bits, but entire bit sequences can be stored in cylindrical domains: tiny, cylindrical areas measuring just around 100 nanometers.

Physicists pool skills to better describe the unstable sigma meson particle

Posted by in categories: computing, particle physics

While nuclear physicists know the strong interaction is what holds together the particles at the heart of matter, we still have a lot to learn about this fundamental force. Results published earlier this year in Physical Review D by three researchers in the Center for Theoretical and Computational Physics at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility bring us closer to understanding an important piece of the strong interaction puzzle.

Illinois lands federal partnership to further develop quantum projects

Posted by in categories: computing, quantum physics

Gov. J.B. Pritzker on Tuesday plans to announce a major partnership with the U.S. Department of Defense’s research and development agency to further expand quantum research in Illinois.

The Defense Advanced Research Projects Agency, or DARPA, will take residency on the state’s quantum campus to establish a program where quantum computing prototypes will be tested. The location of the campus is expected to be announced soon.

According to DARPA, the goal of the “Quantum Benchmarking Initaitive,” or QBI, will be to evaluate and test quantum computing claims and “separate hype from reality.”

Game developer swaps all servers to AMD, claims ‘Intel is selling defective’ CPUs

Posted by in categories: computing, entertainment

Alderon Games, an Australian-based developer behind the dinosaur-themed multiplayer survival game Path of Titans, announced “we are swapping all our servers to AMD” because “Intel is selling defective” CPUs — specifically 13th and 14th Gen models.

The post doesn’t mince words; it states that its customers have been reporting thousands of crashes on Intel 13th and 14th Gen CPUs (verified by the game’s crash reporting tools), and its game servers have been “experiencing constant crashes, taking entire servers down.” It also claims that it’s only a matter of time before Core i9-14900K and Core i9-13900K CPUs that have yet to fail will fail.

“Over the last 3 to 4 months, we have observed that CPUs initially working well deteriorate over time, eventually failing,” Matthew Cassells, Founder of Alderon Games, writes. “The failure rate we have observed from our own testing is nearly 100%, indicating it’s only a matter of time before affected CPUs fail.”

Chips could harvest their own energy using a newly-created alloy

Posted by in categories: computing, mobile phones, sustainability

Why it matters: Electronic devices, which encompass anything from mobile phones to data centers, are notorious energy hogs. One solution could be to harness their heat directly to create a technique for on-chip energy harvesting. The problem has been that none of the few materials able to do this is compatible with current technology in semiconductor fabrication plants. Now, researchers from across Europe have created a germanium-tin alloy that can convert computer processors’ waste heat back into electricity.

A research collaboration in Europe has created a new alloy of silicon, germanium, and tin that can convert waste heat from computer processors back into electricity. It is a significant breakthrough in the development of materials for on-chip energy harvesting, which could lead to more energy-efficient and sustainable electronic devices. Essentially, by adding tin to germanium, the material’s thermal conductivity has been significantly reduced while still maintaining its electrical properties, making it ideal for thermoelectric applications.

The researchers are from Forschungszentrum Jülich and IHP – Leibniz Institute for High Performance Microelectronics in Germany, the University of Pisa, the University of Bologna in Italy, and the University of Leeds in the UK. Their findings made it onto the cover of the scientific journal ACS Applied Energy Materials.
