The equatorial Pacific plays a crucial role in regulating tropical cloud formation and regional weather extremes, earning it the nickname “the pacemaker of global warming.” Though its impact may seem subtle, this oceanic region has been a silent hero, slowing the pace of global warming. Now, climate scientists are on a quest to discover whether this protective mechanism will continue to pulsate in our favor.

During embryonic development, cells proliferate rapidly and differentiate to form tissues and organs of multicellular organisms. Paradoxically, since the 19th century, scientists have discovered that these processes that foster the creation of life is often accompanied by large-scale cell death. Why? This is a century-old mystery. Dr. Sheng-hong Chen and his team from the Institute of Molecular Biology's Lab for Cell Dynamics discovered that large-scale cell death occurs through Reactive Oxygen Species (ROS)-mediated ferroptosis trigger waves, published online in Nature in July 2024.

Topological insulators have an interior that acts as an electrical insulator, with a surface that acts as an electrical conductor. Most of the discovered topological insulators to date have been either three or two-dimensional. But researchers have recently unveiled a one-dimensional topological insulator, with the discovery paving the way for further developments in qubits and solar cells.

Osaka University researchers discovered liver resident macrophages' pivotal role in defending against gut bacteria and related substances entering via the portal vein, particularly under compromised intestinal barrier conditions. Identified as "sentinel macrophages," they are activated by isoallo-lithocholic acid. This finding holds promise for developing preventive and therapeutic strategies for liver chronic inflammatory diseases, such as metabolic dysfunction-associated steatohepatitis (MASH), by enhancing the function of these macrophages to mitigate inflammation and improve treatment efficacy.

New technological development has provided further clues about the origins of life on Earth. An international research group invented an innovative X-ray spectroscopy approach that enabled them to recreate the chemical reactions occurring in liquids at the femtosecond level (a quadrillionth part of a second). They used this to examine ureas—an organic compound that underwent ionization to form some of the building blocks of life.

In hepatic steatosis, hepatocytes "die," resulting in liver damage. Severe steatosis increases hepatocellular deaths, thus aggravating liver damage. The mechanism is unclear. Using mice, we show that mild steatosis causes apoptosis whereas severe steatosis predominantly causes necroptosis leading to cell rupture. This induces strong inflammation and new cell death, producing further liver damage. We reveal the transcription factor ATF3 to be involved in this process. Our results are expected to contribute to therapeutic method development.

Researchers from Osaka University and collaborating partners used common nanofabrication procedures to fabricate versatile metal semiconductor superlattices. These superlattices exhibit a long-sought physical phenomenon—the anisotropic anomalous Hall effect at room temperature. This research will help improve the density of data storage, as well as the functionality of other technologies that also depend on advances in the microelectronics industry.

Researchers have discovered that vitamin K acts as a powerful antioxidant. It can inhibit ferroptosis, a type of cell death associated with Alzheimer’s disease and organ damage, by trapping lipid radicals. Furthermore, the team identified the long-sought-after vitamin K-reducing enzyme, the identity of which remained unknown for more than half a century.

Metals usually soften when they expand under heating, but a research team led by a City University of Hong Kong (CityU) scholar and other researchers have discovered a first-of-its-kind super-elastic alloy that can retain its stiffness even after being heated to 1,000K (about 727℃) or above, with nearly zero energy dissipation. The team believes that the alloy can be applied in manufacturing high-precision devices for space missions.
The research team was led by Professor Yang Yong from CityU’s Department of Mechanical Engineering (MNE), together with his collaborators. The findings were published in the prestigious science journal Nature under the titled “A Highly Distorted Ultraelastic Chemically Complex Elinvar Alloy”.
