There’s a new study that’s getting a fair amount of attention in the climate science community and the popular press.

New research suggests concussion may not significantly impair symptoms or cognitive skills for one gender over another, however, women may still experience greater symptoms and poorer cognitive performance at preseason testing. The study released today will be presented at the Sports Concussion Conference in Denver, July 24 to 26, hosted by the American Academy of Neurology, the world's leading authority on diagnosing and managing sports concussion. The conference will feature the latest scientific advances in diagnosing and treating sports concussion from leading experts in the field.

We know that Greenpeace and other activist groups really,really care about bees. Really.

A new study by researchers at the University of Bari Aldo Moro, Bari, Italy, Geriatric Unit&Laboratory of Gerontology and Geriatrics, IRCCS "Casa Sollievo della Sofferenza", San Giovanni Rotondo, Foggia, Italy, and Istituto Superiore di Sanità (ISS), Roma, Italy, estimates the association between change or constant habits in coffee consumption and the incidence of mild cognitive impairment (MCI), evaluating 1,445 individuals recruited from 5,632 subjects, aged 65-84 year old, from the Italian Longitudinal Study on Aging (ILSA), a population-based sample from eight Italian municipalities with a 3.5-year median follow-up. These findings are published in the Journal of Alzheimer's Disease.

A class of hormonal drugs called aromatase inhibitors substantially reduce the risk of death in postmenopausal women with the most common type of breast cancer, a major study of more than 30,000 women shows.

The research underlines the importance of aromatase inhibitors in the treatment of oestrogen receptor (ER)-positive breast cancer - and shows they reduce risk of death by significantly more than the older hormonal treatment tamoxifen.

The study published in The Lancet is relevant to postmenopausal women with ER-positive breast cancer, which accounts for over 80 per cent of cases which occur after the menopause. Each trial had used both aromatase inhibitors and tamoxifen at various times during the course of treatment.

Researchers have discovered how severely damaged DNA is transported within a cell and how it is repaired. It's a discovery that could unlock secrets into how cancer operates -- a disease that two in five Canadians will develop in their lifetime.

"Scientists knew that severely injured DNA was taken to specialized 'hospitals' in the cell to be repaired, but the big mystery was how it got there," said Karim Mekhail, a Professor in the  University of Toronto Faculty of Medicine's Department of Laboratory Medicine and Pathobiology. "We've now discovered the DNA 'ambulance' and the road it takes."

Mekhail discovered this DNA ambulance, which is a motor protein complex, by using yeast cells. His research was recently published in Nature Communications.
