Measuring the precise quantity of rainfall in a particular area is straightforward when there is equipment specifically designed to accurately capture and relay precipitation data. However, quantifying and identifying the types of precipitation across all locations on Earth presents significant logistical challenges.

Importantly, this information could provide a wealth of data for characterizing and predicting Earth’s water, energy, and biogeochemical cycles. Researchers from China recently deployed a satellite, FengYun 3G (FY-3G), that is successfully collecting Earth precipitation data from space.

Scientists achieve breakthrough in quantum optics with photon detector-based method, paving the way for improved quantum computing.

Scientists at Paderborn University have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors — devices that can detect individual light particles — for so-called homodyne detection. The ability to characterize optical quantum states makes the method an essential tool for quantum information processing. Precise knowledge of the characteristics is important for use in quantum computers, for example. The results have now been published in the specialist journal Optica Quantum.

Advancements in Homodyne Detection.

China ruled on a case of infringement of copyright by an AI-generated service, the first effective ruling of its kind globally, which provided a judicial answer to the dilemma of whether the content generated by AI service providers infringes on copyright, media reported on Monday.

According to the 21st Century Business Herald, the Guangzhou Internet Court ruled that the an AI company had infringed the plaintiff’s copyright and adaptation rights to the Ultraman works in the process of providing generative AI services, and should bear relevant civil liability.

The protagonist of this case was the super IP Ultraman. In this case, the copyright owner of the “Ultraman” works exclusively authorized the copyright of the series images to the plaintiff, while the defendant company operated a website, providing services with AI conversation and AI-generated painting functions.

Scientists used “knowledge distillation” to condense Stable Diffusion XL into a much leaner, more efficient AI image generation model that can run on low-cost hardware.

Buick is in the middle of “an evolution” as it introduces a new design based on the Wildcat EV concept. The company revealed a new tagline and brand campaign, “Exceptional by design,” showcased by a sleek gold Wildcat EV model.

Although Buick has yet to launch its first EV in the US, the automaker is prepping for its next era. The revamp started with an updated tri-shield in June 2022, unveiling the stunning Wildcat EV concept.

Researchers at the University of Massachusetts Amherst recently released a first-of-its-kind study focusing on the rare autoimmune disorder aplastic anemia to understand how a subset of cells might be trained to correct the overzealous immune response that can lead to fatal autoimmune disorders. The research, published in Frontiers in Immunology, identifies a specific enzyme known as PRMT5, as a key regulator of suppressive activity in a specialized population of cells.

The human immune system is a marvel of evolution. When a pathogen enters the body, immune cells can identify it, call for backup, attack the pathogen, and then, when the threat has been eradicated, return to a peaceful state. But sometimes, as in the rare autoimmune disorder aplastic anemia, something goes wrong.

In patients with aplastic anemia, the aberrant immune cells, in this case Th1 cells, misidentify healthy stem cells in bone marrow as pathogenic and attack them. Without these bone marrow stem cells, the body can’t make white blood cells to fight infections, red blood cells to carry oxygen throughout the body, or platelets that help stop bleeding.

This remarkable revelation is the outcome of 15 years’ worth of data collected by the Japanese radio astronomy project known as VERA, or VLBI Exploration of Radio Astrometry. VERA utilizes advanced interferometry techniques, uniting data from radio telescopes across the Japanese archipelago.
