health Scientists directly view immune cells interacting to avert autoimmunity. Using a new form of microscopy to penetrate living lymph nodes, UCSF scientists have for the first time viewed immune cells at work, helping clarify how T cells control autoimmunity. The technique, known as two-photon laser-scanning microscopy, was able to focus deep within the lymph node of a diabetic mouse, allowing the researchers to show that immune cells known as T regulatory, or Treg, cells control the destructive action of rogue autoimmune cells when each of the two cell types interact with a third kind of cell.

happiness People in relationships happier than singles. People in relationships are generally happier than other people, a new Cornell University study finds. And spouses have the highest sense of well-being, whether they are happily married or not. The study of measures of well-being and happiness found that people who cohabit are next on the scale of happiness, followed by those in steady relationships and then those in casual relationships. Unpartnered people report the lowest levels of well-being. [Science Blog -] 2:51:20 PM    comment
