TXA: Inexpensive drug saves blood and money

Using an inexpensive drug for every hip or knee replacement since 2013 has helped St. Michael's Hospital reduce its number of red blood cell transfusions performed during these surgeries by more than 40 per cent without negatively affecting patients, according to new research. The drug tranexamic acid, known as TXA, prevents excessive blood loss during surgeries. read more

Back to school and back to sleep

Poor sleep might explain how stress impacts health in kids, a new study suggests. Researchers found that getting a good night's sleep might buffer the impact of stress on kids' cortisol level, which is a hormone produced in the adrenal gland to regulate the body's cardiovascular, metabolic and immune systems.

Family tree for orchids explains their astonishing variability

Orchids, a fantastically complicated and diverse group of flowering plants, have long blended the exotic with the beautiful. Previously, botanists have proposed more than a half dozen explanations for this diversity. Now, research corroborates many of these explanations, but finds no evidence for other logical suggestions, such as that deceitful pollination.

California rising?

Spatially corrected sea-level records for the Pacific coast indicate that uplift rates are overestimated by 40 percent, scientists report. Uplift is the vertical elevation of Earth's surface in response to plate tectonics.

Popular Herbicide Doesn’t Have Long-term Effect on Water and Aquatic Plant Life

A recent study by a multi-disciplinary team of Baylor University researchers found that a popular herbicide does not appear to have a long-term, measurable impact on aquatic plant life. The study looked at atrazine, a common herbicide...Show More Summary
