The diurnal birds of prey commonly known as raptors play key ecosystem roles as apex predators and carrion eating nutrient cyclers (Donázar 2016, Sekercioglu 2006). These birds also show a wide distribution of morphological traits, particularly differences in feet, beaks, and wings. Previous work has established general connections between functional ecology and morphology, but finer level discrimination on a large scale has yet to be investigated (Pigot , 2020).
Not only do multiple redox processes occur in the wetland's diverse oxygen zones but also a diversified microbial community resides in different layers due to the combination of oxygen-rich and oxygen-low locations. One of the essential elements of built wetland biogeochemistry is the sulfur cycle since it is closely related to the carbon, nitrogen, and iron cycles. To study the sulfur cycle and the hyporheic flux, I examine the composition of the soxB gene which is known for its unique characteristics of executing sulfur oxidation.
Swarms of robots are interesting because of their properties, such as scalability that enables them to scale easily and quickly to hundreds or thousands of robots, flexibility since they can take advantage of changes in the environment, and robustness to robot failures. Swarms of robots can be used for many real-world problems, such as foraging, collective transport of heavy objects, environmental monitoring and cleanup, exploration, and surveillance. From Lu et al.
Properly sanitizing hands is crucial to prevent disease transmission.
Weight stigma, or discrimination based on weight, is prevalent and is associated with negative physiological and psychological consequences. The healthcare setting is one of the main places people experience weight stigma. This study examines how conversations about weight in healthcare settings are related to trust in the healthcare system and trust in healthcare providers among people with obesity.
Recently, there have been increasing calls for integration of mathematics into scientific education. The standard for scientific education has always been the use of methods such as presentation of data and calculated procedures. These methods have been called into question due to their apparent lack of effectiveness in conceptual understanding and problem solving. While these issues are well studied in physics and chemistry, there is less knowledge on this topic in the biological sciences.
Females with chronic gastrointestinal-related immune disorders, such as inflammatory bowel disease (IBD), have higher rates of infertility than women without these disorders. This issue has implications for the health and wellbeing of females desiring children. Previous research has shown that IBD is accompanied by alterations in the gut microbiota. There is evidence that the gut microbiota impacts a control center in the brain known as the hypothalamic-pituitary-gonadal (HPG) axis.
Several insect species adopt a polygamous mating strategy in order to maximize reproductive success. In polygamous mating systems, males have to compete with one another to mate with females. To increase their chances of attracting a mate, male pacific field crickets, Teleogryllus oceanicus, utilize auditory sexual signals. The calling song is produced after a spermatophore (a capsule containing spermatozoa that is extruded by the male) is ready. The males then emit a quieter courtship song when the female makes contact.
Site-directed genome editing technologies in plants have promising potential for plant gene function research and crop improvement .Targeted base editing in plants without a foreign DNA donor or double-stranded DNA cleavage would accelerate genome modification and breeding in plants. Agrobacterium-mediated techniques have been used to generate base editing through in planta transformation or embryogenic callus-based transformation through tissue culture. The generated transgenic lines expressing base-editor and sgRNA have mainly been mosaic in the first generation.
As research into human genetics grows, the role of epigenetics on molecular phenotype, including cancer, has grown with it. Factors outside of chromosomal DNA, including but not limited to chromatin organization, methylation of DNA, and various histone modifications have been associated with changing transcription levels of genes. Perturbed transcription levels, compared to healthy cells, are associated with various cancers, including liver cancer.
