The researchers argue that a 'belief in science' may help non-religious people deal with adversity by offering comfort and reassurance, as has been reported previously for religious belief.

Over-produced autism gene alters synapses, affects learning and behavior in mice Posted: 05 Jun 2013 11:44 AM PDT A gene linked to autism spectrum disorders that was manipulated in two lines of transgenic mice produced mature adults with irreversible deficits affecting either learning or social interaction.

Multiple sclerosis: Phase 1 trial safely resets patients' immune systems, reduces attack on myelin protein Posted: 05 Jun 2013 11:43 AM PDT A phase 1 clinical trial for the first treatment to reset the immune system of multiple sclerosis (MS) patients showed the therapy was safe and dramatically reduced patients' immune systems' reactivity to myelin by 50 to 75 percent. The therapy used billions of patients' own specially processed blood cells to create tolerance to myelin, the insulating layer that forms around nerves. In MS, the immune system attacks myelin. The approach left the normal immune system intact.

Drug prevents post-traumatic stress-like symptoms in mice Posted: 05 Jun 2013 11:39 AM PDT When injected into mice immediately following a traumatic event, a new drug prevents the animals from developing memory problems and increased anxiety that are indicative of post-traumatic stress disorder (PTSD).

Formula-feeding linked to metabolic stress and increased risk of later disease Posted: 05 Jun 2013 10:37 AM PDT New evidence from research suggests that infants fed formula, rather than breast milk, experience metabolic stress that could play a part in the long-recognized link between formula-feeding and an increased risk of obesity, type 2 diabetes and other conditions in adult life.

New study rebuts increase in willingness to cooperate from intuitive thinking Posted: 05 Jun 2013 10:37 AM PDT A study that was presented in Nature last year attracted a great deal of attention when it asserted that intuition promotes cooperation.
