Microscopes at microscopic size

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.

Microarrays as phenotype

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.

Creality K1 Max 3D Printer

Creality K1 Max 3D Printer rapidly prototypes brackets, adapters, and fixtures for instruments and classroom demonstrations at large build volume.

Structure-building cell signals also may influence learning, memory

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.

Sacred constant might be changing

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.
