Researchers identified the tegmentum in the midbrain as an ‘integration center’ of fish. The area receives visual information from the eyes that is combined with color information detected by the pineal organ—the ‘third eye.’ These inputs are integrated to control how fish orient themselves in the water.
Understanding how representative currently known proteins are of the overall potential diversity can help inform strategies for a wide range of applications, including therapeutic, biocatalysis, or biomaterials development. Published in PNAS, an OIST-led international team investigated the relationship between protein evolution and sequence space, identifying the limiting factors behind protein diversification. Their findings reinforce theories of DNA recombination as a driving force of ancestral protein formation and highlight the limitations of many cutting-edge AI protein design methods.
In a study led by researchers from the NRF-DSTI research chair in African Microbiome Innovation at Stellenbosch University (SU), scientists investigated how antimicrobial resistance genes behave in WWTPs and rivers in a large urban city in South Africa. Because of the lack of such studies in Africa, and the potential implications for water reuse, Dr Makumbi and his co-authors conducted a microbiome study to get a sense of what is happening at WWTWs and connected river systems in South Africa.
Scientists have uncovered an unexpected microbial relationship that could help explain differences in the severity of a major disease affecting common beans. The discovery sheds light on how the pathogen evolves and may point to new strategies for breeding disease-resistant crops and reducing reliance on chemical pesticides.
