Brain cell migration during normal development may offer insight on how cancer cells spread
By shedding new light on how cells migrate in the developing brain, researchers at Fred Hutchinson Cancer Research Center also may have found a new mechanism by which other types of cells, including cancer cells, travel within the body.

Combination therapy provides hope for cure of dangerous infections of cystic fibrosis patients
An over-the-counter drug used to treat diarrhea combined with minocycline, an antibiotic used to treat bacterial infections, could one day change the lives of those living with cystic fibrosis.

Molecular movements of neural transporters unveiled
A team of scientists from Columbia University College of Physicians and Surgeons and Weill Cornell Medical College has shed light on the molecular workings of transporter proteins, molecular machines embedded in the cell membranes of neurons that modulate the transfer of signals between cells and recycle neurotransmitters.

Anti-helium discovered in the heart of STAR
Antimatter nuclei of helium-4, the heaviest antiparticles ever found, have been created in the STAR experiment of the Relativistic Heavy Ion Collider at Brookhaven National Laboratory.

Blocking crucial molecule could help treat multiple sclerosis, Jefferson neuroscientists say
Reporting in Nature Immunology, Jefferson neuroscientists have identified a driving force behind autoimmune diseases such as multiple sclerosis (MS), and suggest that blocking this cell-signaling molecule is the first step in developing new treatments to eradicate these diseases.

Study shows artificially induced malaria immunity lasts longer than immunity acquired naturally
A new immunological technique -- in which patients are infected with malaria at the same time as being treated with prophylactic chloroquinine drugs -- can give immunity against re-infection for at least 2.5 years, much longer than is generally recorded for immunity acquired naturally.

RHIC Physicists Nab New Record for Heaviest Antimatter
Members of the STAR collaboration at the Relativistic Heavy Ion Collider--a particle accelerator used to recreate and study conditions of the early universe at Brookhaven National Laboratory--have detected the antimatter partner of the helium nucleus: antihelium-4.

GM-CSF required for the immune attack in multiple sclerosis
The neutralization of the cytokine GM-CSF could halt the development of multiple sclerosis.

RNA dynamics deconstructed
RNA plays a critical role in directing the creation of proteins, but there is more to the life of an RNA molecule than simply carrying DNA's message.
