Osaka University researchers discovered a concerning association between bacteremia and probiotic use, particularly with Clostridium butyricum (C. butyricum) MIYAIRI 588. Whole-genome sequencing revealed that all C. butyricum bacteremia strains were probiotic derivatives. Out of 6,576 cases of positive blood cultures, C. butyricum was detected in only five cases, all derived from probiotics. The study underscores rare but serious adverse events linked to probiotics, advocating cautious prescribing practices, especially for hospitalized patients.
Charge-recharge cycling of lithium-superrich iron oxide, a cost-effective and high-capacity cathode for new-generation lithium-ion batteries, can be greatly improved by doping with readily available mineral elements.
Kumamoto University researchers have identified a novel Heat Shock Factor (HSF), designated as HSF5, which plays a crucial role in the completion of meiosis and the activation of genes essential for sperm formation. This discovery provides valuable insights into underlying causes of spermatogenic failure, the major contributor to male infertility. Furthermore, unlike other typical Heat Shock Factors, which primarily regulate gene expression in response to stress, such as heat shock, HSF5 plays a specific role in male germ production during meiosis under non-stress conditions.
For the first time since 1914, a new species of the Japanese lily known as sukashiyuri has been identified. An Osaka Metropolitan University-led research team analyzed the morphology and DNA of these lilies and has revised the conventional classification from four taxonomic groups to eight.
How do planets form? How do galaxies evolve? And ultimately, how did the universe itself begin? A unique astronomical observatory that researchers hope will unravel some of the biggest mysteries out there marks its opening on April 30, 2024.
At an altitude of 5,640 meters, the University of Tokyo Atacama Observatory (TAO), built on the summit of a desert mountain in northern Chile, is the highest astronomical observatory in the world, which should give it unrivaled capabilities, but presents some novel challenges.Quadcopters, the most popular type of low-cost drone, are being extensively used in many industrial fields. However, introducing grasping capabilities into these lightweight flying devices is challenging. In a recent study, researchers developed a self-folding origami gripper, which can be attached to a quadcopter to enable it to grasp small objects. Thanks to its low weight, respectable holding strength, and biodegradable properties, the proposed design could revolutionize how origami technology is incorporated into quadcopters.
