A complex molecular machine, the spliceosome, ensures that the genetic information from the genome, after being transcribed into mRNA precursors, is correctly assembled into mature mRNA. Splicing is a ...

New research details the subcellular structures in neurons that enable signals to be transmitted from where they are received at specific sites on dendrites to the decision-making cell body located ...

NGC 922 is a peculiar galaxy in the southern constellation of Fornax. This beautiful image was captured by NASA's Hubble Space Telescope. NGC 7049 is a lenticular galaxy that spans about 150,000 light ...

The course provides an introduction into using electron microscopic technology (EM), and includes both Transmission electron microscopy (TEM) and Scanning electron microscopy (SEM). The course will ...

Trypanosomes are parasites that cause sleeping sickness, Chagas disease, and various animal diseases. Diagnosis and treatment remain complex and no effective vaccine has been developed. A better ...

Trypanosomes—like other living organisms—transcribe their DNA into messenger RNAs ... "I was using cryo-electron microscopy (cryo-EM) to generate a structure of the complex, but the flexible ...

Morphological examination relies on each cell type's consistent and defining traits, traditionally performed through blood smears and bone marrow aspiration, where cell morphology is assessed under ...

The system detects and degrades viral DNA before the virus can replicate ... the researchers used several advanced techniques, including cryo-electron microscopy which help see very small structures, ...
