The team discovers “dark oxygen” at the bottom of the sea
Credit: CC0 Public Domain Children always ask, “Why?” It’s natural to want to know more as they are the first time they’re experiencing things. But as children grow into adults, they often dismiss something new that challenges their experiences and understanding. This happened when we discovered a source of oxygen production in the deep sea, but we ignored it for…

Research team develops more comprehensive method to monitor lobster industry
Credit: CC0 Public Domain Maine’s lobster fishery supports thousands of jobs across the state and is extensively monitored. Management efforts are informed by biological monitoring surveys that observe changes in lobster abundance and distribution, as well as dealer and harvester reports from the industry. But these statistics do not tell the whole story of an industry reeling from supply, market…

Team uses optogenetics technology to manipulate intracellular signaling
Credit: Development (2025). DOI: 10.1242/dev.204403 A research team led by Dr. Tetsuya Muramoto of Toho University’s Faculty of Science has demonstrated a mechanism by which periodic chemical signal frequencies within cells regulate gene expression through transcription factors and influence cell fate decisions. This discovery was made using optogenetic technology, which uses light to facilitate the manipulation of biological phenomena. The…

Team investigates population genetic characteristics of two hybrid crucian carp lines
Central linkage network based on Tf alleles. Credit: Reproduction and Breeding (2024). DOI: 10.1016/j.repbre.2024.07.002 Crucian carp (Carassius auratus) is a common freshwater fish in China, and its farming mainly relies on artificially bred superior varieties. A hybrid strain derived from Carassius cuvieri (♀) × C. auratus red var. (♂) (HFJ) and new homodiploid crucian carp-like lineages derived from carp (♀)…

Team develops non-invasive biosensor for early detection of kidney disease
Researchers have developed a biosensor that uses affinity peptides to detect symmetrical dimethylarginine (SDMA), an early marker of kidney problems. This sensor measures SDMA levels in urine with high accuracy, making it a practical and cost-effective tool for early diagnosis and monitoring.

Team synthesizes cost-effective and durable non-precious metal alloy as an alternative to iridium oxide anodes
Credit: Yoshikazu Ito Despite the growing importance of hydrogen as a future energy source, transporting gaseous hydrogen safely and on a large scale remains challenging. Researchers are exploring ways to transport hydrogen in the form of liquid methylcyclohexane (MCH) by reacting it with toluene. One such approach is organic hydride electrosynthesis. In this process, toluene is transferred from the cathode…

Team develops promising new form of antibiotic that causes bacterial cells to self-destruct
Credit: Journal of Medicinal Chemistry (2024). DOI: 10.1021/acs.jmedchem.4c00773 To address the global threat of antibiotic resistance, scientists are exploring new ways to bypass bacterial cell defense systems. Researchers at the University of Toronto (U of T) have used what they learned from previous research on cancer to develop a new compound that causes bacterial cells to self-destruct. The research team’s…
