Association between low vitamin D and MS

Low levels of vitamin D significantly increase the risk of developing multiple sclerosis (MS), according to a study led by Dr. Brent Richards of the Lady Davis Institute at the Jewish General Hospital, and published in PLOS Medicine. This finding, the result of a sophisticated Mendelian randomization analysis, confirms a long-standing hypothesis that low vitamin D is strongly associated with an increased susceptibility to MS. This connection is independent of other factors associated with low vitamin D levels, such as obesity.

Gestational diabetes: A diabetes predictor in fathers

In a large study analyzing 20 years of data from Quebec, a team from the Research Institute of the McGill University Health Centre (RI-MUHC) has demonstrated that gestational diabetes signals future diabetes risk not only in mothers, but also in fathers. The study was recently published in Diabetes Care.

Breakthrough in "marriage-broker" protein

Scientists at the Montreal Neurological Institute and Hospital -The Neuro, at McGill University and the McGill University Health Centre, have made a breakthrough in understanding an important protein that appears to act as a kind of cellular “marriage broker.” The protein called Netrin1 brings cells together and maintains their healthy relationships. Netrin1 plays an essential role in the growth of the human organism, directing cell migration and the formation of cell circuits both at the embryo stage and after birth.

The personalities of spiders

Even jumping spiders have personalities scientists have discovered. A "shy" individual will not make the same choices as a "bold" individual. This means that some individuals, because of their personality type, will capture more prey than others, and will therefore have a larger effect on local ecosystems.
