Response to immune protein determines pathology of multiple sclerosis

New research may help reveal why different parts of the brain can come under attack in patients with multiple sclerosis. According to a new study in mice with an MS-like disease, the brain’s response to a protein produced by invading T cells dictates whether it’s the spinal cord or cerebellum that comes under fire. The study will be published online on Oct. 13 in the Journal of Experimental Medicine.

Scientists trace molecular origin of proportional development

When it comes to embryo formation in the lowly fruit fly, a little molecular messiness actually leads to enhanced developmental precision, according to a study in the Oct. 14 Developmental Cell from Cincinnati Children’s Hospital Medical Center. The study provides new information about how cells choose their own fates, especially in maintaining the size relationship and proportionality of body parts during embryonic development.

Despite ‘peacenik’ reputation, bonobos hunt and eat other primates too

Unlike the male-dominated societies of their chimpanzee relatives, bonobo society — in which females enjoy a higher social status than males — has a “make-love-not-war” kind of image. While chimpanzee males frequently band together to hunt and kill monkeys, the more peaceful bonobos were believed to restrict what meat they do eat to forest antelopes, squirrels and rodents.

In a last ’stronghold’ for endangered chimpanzees, survey finds drastic decli…

In a population survey of West African chimpanzees living in Côte d’Ivoire, researchers estimate that this endangered subspecies has dropped in numbers by a whopping 90 percent since the last survey was conducted 18 years ago. The few remaining chimpanzees are now highly fragmented, with only one viable population living in Taï National Park, according to a report in the Oct. 14 issue of Current Biology, a Cell Press publication.
