A low-dose CT scan can detect lung cancers at relatively early stages and reduce deaths from lung cancer by as much as 20%, according to a new study. The trial was halted early because of the positive results.
Harmful alcohol use drops among college students when universities and surrounding communities target the places off-campus where drinking occurs, a new study shows. Similar strategies may help counter the problems of excess drinking on campuses nationwide.
Researchers have discovered mutations in a particular gene that affects the treatment prognosis for some patients with acute myeloid leukemia (AML), an aggressive blood cancer that kills 9,000 Americans annually. The finding may lead to more effective treatments for patients who carry the mutations.

Scientists used a brain-computer interface to show how the activity of just a few brain cells can control the display of pictures on a computer screen. The finding sheds light on how single brain cells contribute to attention and conscious thought.
A drug commonly used to treat lead poisoning is relatively ineffective at removing mercury from the blood. The finding provides insight into a compound currently being used as an alternative therapy for autism.
The mosquito species most responsible for spreading malaria in Africa seems to be evolving into 2 separate species with different traits, researchers have found. The development may complicate efforts to control the disease.

Researchers have published the most detailed map of human genetic variation so far. Scientists will use this resource to help identify genetic contributions to rare and common diseases.
Heart patients taking a widely used anti-clotting drug are at increased risk for serious cardiovascular problems if they have 1 or 2 copies of a common gene variant. The finding adds critical information for personalizing medications based on genetic makeup.
Researchers discovered a new pathway for the development of Th17 cells, a type of helper T cell involved in autoimmunity. The finding reveals potential new targets for treating autoimmune diseases.
