A gene is a unit of heredity in a living organism. It normally resides on a stretch of DNA that codes for a type of protein or for an RNA chain that has a function in the organism. All living things depend on genes, as they specify all proteins and functional RNA chains.

Genetic Sequencing Leads to Major Discovery in Neurodevelopmental Disorders

A seminal study from researchers at the Icahn School of Medicine at Mount Sinai and their collaborators in the United Kingdom, Belgium, Spain, the Netherlands, and Iceland has uncovered a new genetic cause of neurodevelopmental disorders (NDDs).

Study Sheds Light on Development and Evolution of the Human Hypothalamus

The hypothalamus is a small but critical region at the base of the brain that controls the autonomic nervous system, regulates body temperature, signals hunger and thirst, exerts hormonal control over the pituitary gland, helps set circadian rhythms, influences sexual behavior and reproduction, and plays a role in instinctive behaviors like fear, aggression, and maternal bonding.

New Research Reveals Mitochondrial Guardians Linked to Parkinson’s and ALS

Scientists at Johns Hopkins Medicine say they have discovered how a group of proteins linked to Parkinson's disease and amyotrophic lateral sclerosis act as "guardians" of mitochondria, small organelles, or subunits, within a cell that make and store energy and are found in almost all plants and animals.

Spinning Into Resistance: The Flagella’s Hidden Role

A new study from the Hebrew University of Jerusalem reveals that bacterial movement plays a central role in the transfer of antibiotic resistance genes. The research team discovered that the rotation of flagella in Bacillus subtilis acts as a mechanical signal that activates key conjugation genes.

Scientists Discover Epigenetic Marks in Pancreatic Cancer Transition

Johns Hopkins Medicine scientists say they have found a pattern of so-called epigenetic "marks" in a transition state between normal and pancreatic cancer cells in mice, and that the normal cells may keep at least a temporary "memory" of those cancer-linked marks.
