525-million-year-old fossil contradicts textbook theory of brain evolution
Updated : 3 years, 3 months ago IST
According to a new study, fossils of a tiny sea creature with a delicately preserved nervous system solve a century-old debate over how the brain evolved in arthropods, the most species-rich group in the animal kingdom. Combining detailed anatomical studies of the fossilized nervous syste

Discovery suggests new way to target mantle cell lymphoma
Updated : 3 years, 3 months ago IST
A form of blood cancer known as mantle cell lymphoma is critically dependent on a protein that coordinates gene expression, such that blocking its activity with an experimental drug dramatically slows the growth of this lymphoma in preclinical tests, according to a study from Weill Cornell M

Study shows age often plays bigger role than genetics in gene expression,
Updated : 3 years, 5 months ago IST
Washington [US], October 8 (ANI): Our genetics, the environment and our age all play important roles in our health, but which of these is the most important? A new study suggests that in many cases, age plays a more important role than genetics in determining which genes in our bodies are tu

DNA methylation in bacteria regulates virulence, reproduction, and gene ex
Updated : 3 years, 8 months ago IST
Houston [Texas], July 2 (ANI): According to research, DNA methylation in bacteria regulates virulence, reproduction, and gene expression. DNA methylation is crucial for controlling the tissue-specific gene expression that determines a cell's identity, such as whether it is a skin cell or a b
