Life on the ice: living bacteria found in polar ice and snow

This analysis of ice cores relies on the assumption that there is limited biological activity altering the environment in the snow during its transition into ice. Research reported in the Journal of the Royal Society Interface, which has directly observed microbial activity in Antarctic and Arctic snow, has revealed that the composition of these small samples of gas trapped in the ice may have been affected by bacteria that remain active in snow while it is being compressed into ice — a process that can last decades.

Presurgical Imaging Predicts the effectiveness of Epilepsy Surgery

Surgery to remove a part of the brain to give relief to patients with epilepsy does not always result in complete seizure relief. However, Marina Vannucci and lead author Sharon Chiang from Rice University developed a method for integrating functional magnetic resonance imaging (fMRI) and positron emission tomography (PET) scans to find visual biomarkers that distinguish patients with the greatest likelihood of benefit. The study was appeared in Frontiers in Neuroscience. 

Walking blood banks: An immediate solution to Rural India’s Blood Scarcity

The current system of blood banks in India is such that rural patients are deprived of timely access to an adequate volume of life-saving blood, adding to preventable mortality. On the basis of an academic framework for a blood transfusion system, an alternative approach in which rural practitioners utilize unbanked blood transfusions from a voluntary pool of pre-screened donors was described.

Study Explores Thyroid’s Role in Mammalian Seasonal Changes

A new led by Nagoya University researchers provides the deeper knowledge of the role that thyroid hormones, the tissues that produce them, and the biochemical pathways on which they act have in driving seasonal reproduction in some mammals, and how this new information may help explain seasonal changes in metabolism and mood that affect humans.

The review article entitled "Seasonal Rhythms: The Role of Thyrotropin and Thyroid Hormones" is part of a special section on Japanese Research in the January issue of Thyroid, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers and the official journal of the American Thyroid Association (ATA).
