Scientists have used next-generation DNA sequencing tools to identify a mutation in a gene that underlies one of the most common forms of severe hypertension.
Neurons that control aggression and mating are closely intertwined deep within the brain.
Researchers gain a new view of how genes are converted to protein by freezing the action during the earliest stage of the process.
Researchers at Stanford University have discovered that they may be able to tweak cancer cells so that they summon their own demise.
In mice with light-sensitive neurons in their brain, illuminating one type of neuron drives the animals to their food bowls, whereas targeting a different type makes them abstain.
After a rapid genetic analysis of bacteria collected from Haitian patients, scientists conclude that the strain of cholera currently sweeping through post-earthquake Haiti originated in South Asia.
