Some Immune Cells Defend Only One Organ

April 17, 2014 1:52 pm | Comments

Scientists have uncovered a new way the immune system may fight cancers and viral infections. The finding could aid efforts to use immune cells to treat illness. The research, in mice, suggests that some organs have the immunological equivalent of “neighborhood police” – specialized squads of defenders that patrol only one area, a single organ, instead of an entire city, the body.

New Technique Will Accelerate Genetic Characterization of Photosynthesis

April 16, 2014 1:26 pm | Comments

Photosynthesis provides fixed carbon and energy for nearly all life on Earth, yet many aspects of this fascinating process remain mysterious. For example, little is known about how it is regulated in response to changes in light intensity. More fundamentally, we do not know the full list of the parts of the molecular machines that perform photosynthesis in any organism.

The Key to Easy Asthma Diagnosis is in the Blood

April 16, 2014 1:07 pm | Comments

Using just a single drop of blood, a team of UW-Madison researchers has developed a faster, cheaper and more accurate tool for diagnosing even mild cases of asthma. This handheld technology—which takes advantage of a previously unknown correlation between asthmatic patients and the most abundant type of white blood cells in the body—means doctors could diagnose asthma even if their patients are not experiencing symptoms during their visit.
