Study of oceans’ past raises worries about their future

Data from end of the last ice age illuminate the precarious nature of global ocean chemistry
Thu, 2013-06-13 15:11

The ocean the Titanic sailed through just over 100 years ago was very different from the one we swim in today. Global warming is increasing ocean temperatures and harming marine food webs. Nitrogen run-off from fertilizers is causing coastal dead zones. A McGill-led international research team has now completed the first global study of changes that occurred in a crucial component of ocean chemistry, the nitrogen cycle, at the end of the last ice age. The results of their study confirm that oceans are good at balancing the nitrogen cycle on a global scale. But the data also shows that it is a slow process that may take many centuries, or even millennia, raising worries about the effects of the scale and speed of current changes in the ocean.

How does inbreeding avoidance evolve in plants?

Case study of Leavenworthia suggests that loss of complex traits may be reversed.

Inbreeding is generally deleterious, even in flowering plants. Since inbreeding raises the risk that bad copies of a gene will be expressed, inbred progeny suffer from reduced viability.

Childhood abuse leaves marks in the brain

Different forms of early childhood trauma can increase the risk for mental illness in adulthood. Scientists of Charité University Medicine in Berlin, Germany, and McGill University, have now discovered a neural basis for this association. Their study, published in the current issue of the American Journal of Psychiatry, shows that sexually abused and emotionally maltreated children exhibit changes in the architecture of their brain that reflect the nature of the maltreatment.
Tue, 2013-06-04 13:07

Victims of childhood maltreatment or sexual abuse often suffer from serious psychiatric disorders as well as sexual dysfunction. The underlying mechanisms mediating this association are poorly understood. A group of scientists lead by Prof. Christine Heim, Director of the Institute of Medical Psychology at Charité University Medicine Berlin, together with Prof. Jens Pruessner, Director of the McGill Centre for Studies in Aging, at McGill University used magnetic resonance imaging (MRI) to examine 51 adult women who were exposed to various forms of childhood maltreatment. The scientists measured the thickness of the cerebral cortex, where sensations from all parts of the body are processed.

Calcium supplements linked to longer lifespans in women

Calcium-rich diet and supplements provide similar benefits
Wed, 2013-05-22 15:02

Taking a calcium supplement of up to 1,000 mg per day can help women live longer, according to a study whose lead author was Lisa Langsetmo, a Ph.D. Research Associate at McGill University, and whose senior author was Prof. David Goltzman, Division of Endocrinology and Metabolism in the Department of Medicine of the Faculty of Medicine and researcher in the Musculoskeletal Disorders axis at the Research Institute of the McGill University Health Centre (RI-MUHC).Their findings are published in the Journal of Clinical Endocrinology & Metabolism (JCEM).
