High-voltage direct current (HVDC) lines are often described as the power highways of the clean-energy era, carrying large amounts of electricity across long distances with high efficiency. 

Osaka Metropolitan University researchers developed an AI-driven transfer-learning method that refines volume size factor predictions from first-principles calculations, enabling more reliable prediction of properties in previously unexplored alloy systems.

Quantum random number generators play a crucial role in securing high-demand information contexts by producing true random numbers. Nevertheless, the large volume and high cost limit their widespread use. Here, a system on-chip is proposed that fully leverages the advantages of different photonic integrated platforms, where the interference optical paths and photodiodes are integrated on a standard silicon process, while the laser source on-chip is realized on a III–V platform. Using micro-lens coupling package technology with coupling loss lower than 2 dB, the components on different platforms are combined and packaged with the amplifier circuits in a 42 mm × 24 mm footprint in a butterfly form. This miniaturized and cost-effective entropy source enables outputting a vacuum noise signal with a 3-dB bandwidth of over 500 MHz. After sampling and post-processing, a random number generation rate of up to 6.57 Gbps is achieved.

Getting sick can look very different for people with Down syndrome (DS); illnesses that are mild for most people may lead to serious complications, including pneumonia, hospitalization or intensive care.

Scientists have long known that excess hydrogen sulfide — a naturally occurring gas that becomes harmful when it accumulates in cells — has been a contributing factor for susceptibility to infections for people with DS. For years, researchers have believed that a chromosome 21 gene called CBS was largely responsible for this overproduction.

But now, researchers at the Texas A&M University College of Veterinary Medicine and Biomedical Sciences (VMBS) and the Texas A&M Health Institute of Biosciences and Technology (IBT) have identified evidence for a previously unknown pathway that may help explain those immune challenges.

The Korea Institute of Civil Engineering and Building Technology (KICT, President Park, Sun-Kyu) announced that it will apply its early detection technology for quasi-stationary linear rainband and sudden localized torrential rainfallto the Urban Flood Forecasting Platform operated by the Han River Flood Control Office in Korea for urban flood forecasting.
