Alcoholic and non-alcoholic fatty liver disease (NAFLD) are well-known risk factors for colorectal cancer (CRC). NAFLD has emerged as a heterogenous disease tightly linked to metabolic dysfunction and has been redefined under the umbrella term ‘steatotic liver disease’ (SLD). However, CRC risk variations across different SLD subgroups remain unknown. Now, researchers from Japan have discovered that the risk of CRC varies significantly among SLD subgroups, with patients with alcoholic liver disease being at higher risk.

Osaka Metropolitan University researchers have succeeded in generating high-quality feline embryonic stem cells using sperm and eggs from testes and ovaries discarded during sterilization surgery.

Recent advances in astronomical observations have found a significant number of extrasolar planets that can sustain surface water, and the search for extraterrestrial life on such planets is gaining momentum. A team of astrobiologists from Astrobiology Center, National Institute for Basic Biology, and SOKENDAI have proposed a novel approach for detecting life on ocean planets. By conducting laboratory measurements and satellite remote sensing analyses, they have demonstrated that the reflectance spectrum of floating vegetation could serve as a promising biosignature. Seasonal variations in floating vegetation may provide a particularly effective means for remote detection.

The results of this research will be published in the journal Astrobiology on February 24, 2025.

Novel protein cage system can control and visualize orientational changes in aromatic side chains upon ligand binding, as reported by researchers at Institute of Science Tokyo. By inducing coordinated molecular changes, this approach enables precise control over protein dynamics while also enhancing fluorescence properties. Their breakthrough could lead to applications in biomolecular robotics, drug delivery, and advancing the development of responsive biomaterials.

Electrons possess electrical charge but also magnetic spin and orbital angular momentum. While charge and spin currents have driven advancements in electronics and spintronics, respectively, generating “orbital currents” has remained a challenge. An international research team has now successfully observed “orbital pumping,” a new phenomenon in which orbital currents are generated from the precession of magnetization in magnetic materials. The discovery could provide the foundation for “orbitronic” technologies based on orbital currents.

New double network hydrogel technology features automated self-strengthening that rapidly activates upon deformation of its polymer network.

An Osaka Metropolitan University research team observing anemonefish in the field found they engage in interesting feeding behavior with their host sea anemones.
