In recent years, an emerging zoonotic pathogen called E. albertii, transmitted by wild animals such as raccoons, has garnered attention due to its remarkable similarities to several strains of Escherichia coli (E. coli), including O157, and its potential to cause severe illness, particularly in children. A research group at Osaka Metropolitan University has developed a novel culture medium that allows for the selective cultivation of E. albertii from raccoon fecal samples. This enabled the successful isolation of E. albertii even from samples with very low quantities of this bacterium. Their findings are expected to further elucidate the bacteriological characteristics of E. albertii and to contribute to the control of foodborne illnesses.

A long-lived monocarpic species of bamboo, Phyllostachys nigra var. henonis, only flowers once every 120 years before it dies. The upcoming flowering event for this species does not bode well for its continued long-term survival, as most flowers are not producing viable seeds.

Certain types of fungi can communicate with each other via electrical signals. But much remains unknown about how and when they do so. A group of researchers recently headed to the forest to measure the electrical signals of Laccaria bicolor mushrooms, finding that their electrical signals increased following rainfall.

A group including Osaka Metropolitan University researchers discovered that the rhodopsin—a protein in the eye that detects light—of whale sharks has changed to efficiently detect blue light, which penetrates deep-sea water easily. The amino acid substitutions–one of which is counterintuitively associated with congenital stationary night blindness in humans—aid in detecting the low levels of light in the deep-sea. Although these changes make the whale shark rhodopsin less thermally stable the deep-sea temperature, allows their rhodopsin to keep working. This suggests that the unique adaptation evolved to function in the low-light low-temperature environment where whale sharks live.

Researchers from Osaka University have developed a culture system using pluripotent cells from southern and northern white rhinos, which was refined to produce primordial germ cell-like cells (PGCLCs). These cells are the equivalent of primordial germ cells, the origin of eggs and sperm. The study marks an important first step in the potential production of northern white rhino gametes, which could be used in breeding programs, and is the first to induce PGCLCs in a wild animal.

Milling rice to separate the grain from the husks, produces about 100 million tons of rice husk waste globally each year. Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the first silicon quantum dot LED light. Their new method transforms agricultural waste into state-of-the-art light-emitting diodes in a low-cost, environmentally friendly way.

Just as humans may leave their home five minutes early to avoid a talkative neighbor or depart work late to avoid a rude coworker, carnivorous mammals may go out of their way to avoid other species. But they’re not trying to navigate awkward social interactions; rather, they are negotiating space and resources for survival.

Coral reefs, comprising some of the most diverse and delicate ecosystems under water, are under immense stress. From global warming to pollution to pathogens, many of the reef-building coral species are listed as threatened or endangered. But, according to researchers in Japan, the corals may have an unlikely ally: bacteria.

A collaboration between Osaka City University and Setsunan University sheds light on the effect urbanization has on the flesh fly species Sarcophaga similis. Through a series of laboratory and in-field experiments, scientists show that an increase in nighttime illumination and temperature, two of the major characteristics of urbanization, can postpone S. similis hibernation anywhere from 3 weeks to a month.
