RAM Is So Expensive, Samsung Won’t Even Sell It To Samsung
A severe spike in global DRAM prices has pushed Samsung Semiconductor to refuse a long-term RAM order from its own sibling, Samsung Electronics. The move is forcing the smartphone division into short, expensive renegotiations, which will likely mean higher costs for consumer devices. PCWorld reports: Samsung subsidiaries are, naturally, going to look to Sa … ⌘ Read more

Physicists Reveal a New Quantum State Where Electrons Run Wild
ScienceDaily reports:
Electrons can freeze into strange geometric crystals and then melt back into liquid-like motion under the right quantum conditions. Researchers identified how to tune these transitions and even discovered a bizarre “pinball” state where some electrons stay locked in place while others dart around freely. Their simulations hel … ⌘ Read more

Spins influence solid oxygen’s crystal structure under extreme magnetic fields, study finds
Placing materials under extremely strong magnetic fields can give rise to unusual and fascinating physical phenomena or behavior. Specifically, studies show that under magnetic fields above 100 tesla (T), spins (i.e., intrinsic magnetic orientations of electrons) and atoms start forming new arrangements, promoting new phases of matter or stretching a crystal lattice. ⌘ Read more

“This is not a Chinese bus problem. It is a problem for all types of vehicles and devices with Chinese electronics built in.”, says in the article.
Sorry but no. The truth is that “This is not an all types of vehicles and devices with Chinese electronics built in problem. It is a problem for all types of remotely accessible vehicles.”
Fuck me! I made a giant mess by knocking over the fresh cup of hot chocolate. I completely soaked my desk, t-shirt, pants, socks, house shoes, seat pad, chair, footstool, chair mat and floor. Showering beforehand was well worth it. :-D Let’s see where I will locate the smell of spoiled milk in the next days. Maybe underneath the baseboard? I’ll take bets.
At least my aiming skills are pretty good. I missed keyboard, mouse and other electronics.
Calorimetric experiment achieves tightest bound on electron neutrino mass
In a Physical Review Letters study, the HOLMES collaboration has achieved the most stringent upper bound on the effective electron neutrino mass ever obtained using a calorimetric approach, setting a limit of less than 27 eV/c² at 90% credibility. ⌘ Read more
Exploring how dark matter alters electron-capture supernovae and the birth of neutron stars
Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of the sun. These stars develop oxygen-neon-magnesium cores, which become unstable when electrons are captured by neon and magnesium nuclei. ⌘ Read more
Generation of harmful slow electrons in water is a race between intermolecular energy decay and proton transfer
When high-energy radiation interacts with water in living organisms, it generates particles and slow-moving electrons that can subsequently damage critical molecules like DNA. Now, Professor Petr Slavíček and his bachelor’s student Jakub Dubský from UCT Prague (University of Chemistry and Technology, Prague) have described in detail one of the key mechanisms for the creation … ⌘ Read more
