Scientists create biochips that allow analysis of cells using fluorescent chemicals and tiny lasers, enabling examination of cellular conditions for diseases and developing new treatments. The technology has the potential to create small diagnostic devices for medical diagnostics, improving patient treatment by reducing hospital visits.
Researchers identified a gene variant that increases the risk of rheumatism, MS, and myocardial infarction by 20-40%. The discovery may lead to more reliable diagnostics and better treatments for patients.
Researchers used microarray data to determine the order of genes in a pathway that results in a particular phenotype. By analyzing the interactions between genes, they were able to reconstruct the pathway and prove that gene A comes before gene B.
Adolescent girls who engage in radical weight-control behaviors, depression, and perceive their parents' weight as obese are more likely to become obese. Erratic eating and lack of exercise do not strongly predict obesity.
Researchers found that ephrin subtype EphrinB activates the EphB receptor, triggering a chemical pathway that stimulates synaptojanin-1 enzyme, essential for cellular endocytosis. This process is crucial for neurotransmitter regulation and nerve cell function.
Scientists have developed a new breed of fibre-optic sensors that can measure strain, detect movements, and monitor blast-waves with high accuracy. These sensors promise to revolutionize safety monitoring in various industries.
Research by Dr. Michael Murphy suggests that the fine structure constant, governing electromagnetic forces, may have changed over time by about one part in two-hundred-thousand during the last 10 billion years. This finding challenges existing knowledge and could have significant implications for our understanding of the universe.
