One Treatment For Insomnia May Actually Slow Biological Aging - ScienceAlert

For the first time since 2014, the American College of Obstetricians and Gynecologists has updated its guidelines for the treatment of symptoms commonly associated with menopause. For the first time since 2014, the American College of Obstetricians and Gynecologists has updated its guidelines for the treatment of symptoms commonly associated with menopause. The doctor's group, known as ACOG, recommends hormone replacement therapy alongside certain antidepressants, nonhormonal medicines, and other treatments to address symptoms like hot flashes, insomnia and mood swings. "What's changing is the breadth of options that we now have … And the benefit of that is that we are better equipped to be able to take an individualized approach for patients," said Catherine Cansino, MD, MPH, an obstetrician/gynecologist, chair of ACOG's Committee on Clinical Practice Guidelines and co-author of the new guidance.

The spacecraft delivered materials and equipment for new research studies to the station.

Mud from a fjord shows an Atlantic air pattern brought wetter, colder spells to southern Greenland, a clue to how its ice may fare. Greenland’s ice is shrinking as the planet warms. But in the island’s southwest, rainfall and snowfall have been influenced by the same North Atlantic air-pressure pattern for at least 5,000 years. When that pattern tipped one way, the region turned wetter and colder. The record comes from mud on the floor of a Greenland fjord, and it suggests snowfall, not only temperature, shaped how the area’s ice grew and shrank. It doesn’t yet show how glaciers there will respond to the warming ahead. Johan Faust, a researcher at MARUM, the Center for Marine Environmental Sciences at the University of Bremen in Germany, led the work with colleagues in Germany, Norway, Denmark and Canada. A seesaw in the airThe pattern is called the North Atlantic Oscillation. It’s the difference in air pressure between a low that sits near Iceland and a high near the Azores, and it’s strongest in winter. When that difference is large, the pattern is in its positive phase. Northwestern Europe and southwestern Greenland both get more rain and snow.
