A new species of black, slender moray eel has chosen the road less traveled, thriving in dim and muddy river mouths, unlike most of its marine relatives. It is found across the Central Indo-Pacific, including within the cave of the Puerto Princesa Subterranean River. This new moray eel is named after the underworld god Hades for its distinctive habitat, unique behaviors, and most notably, its deep, dark coloration. The study was published in the open access journal ZooKeys.

A team from Osaka University has reported a Raman microscopy technique that produced images up to eight times brighter than those achieved with conventional Raman techniques. Imaging of frozen biological samples reduced the noise introduced by the motion of material over long acquisition times. The technique is expected to broaden understanding in many areas of the biological sciences by allowing high-quality images and chemical information to be captured without the need for staining.

In a paper published in Molecular Biomedicine, the authors underscore the heterogeneity of Cancer-associated fibroblasts (CAFs) by elaborating on their origins, types and function. Most importantly, by elucidating the direct or indirect crosstalk between CAFs and immune cells, the extracellular matrix, and cancer cells, they emphasize the tumorigenicity of CAFs in cancer. Finally, they highlight the challenges encountered in the exploration of CAFs and list targeted therapies for CAF, which have implications for clinical treatment.

A new study by Tel Aviv University and Ben-Gurion University of the Negev reveals groundbreaking findings about the famous Rujm el-Hiri site (known as the "Wheel of Ghosts") in the Golan Heights. Based on geomagnetic analysis and tectonic reconstruction, the researchers determined that geodynamic movement over 150 million years, at an average rate of 8–15 mm per year, caused significant shifts in the ground, rotating and reorienting it over millennia. This finding challenges the widely held theory that the structure was used as an astronomical observatory, as the original alignment of the walls and entrances does not correspond to celestial observations, as previously hypothesized.

The creation of more fox-free safe havens and greater collaboration between government and landowners is needed to ensure the survival of a species of wallaby, an expert from The Australian National University (ANU) argues. 

The Parma wallaby, also known as the white-throated wallaby, is listed as a vulnerable species in Australia, while the International Union for Conservation of Nature (IUCN) classifies it as Near Threatened. The marsupial is found along the Great Dividing Range in northern New South Wales.
