Women who use estrogen replacement therapy to relieve menopausal symptoms are more likely to develop risk factors for potentially fatal irregular heartbeats (arrythmias) and heart attacks than women who take hormone therapy combining estrogen and progestin.
Prior to the early termination of the estrogen plus progestin arm of a nationwide womens health study, postmenopausal hormone replacement therapy was the most commonly prescribed medication in the United States, based on its alleged cholesterol-lowering and cardioprotective effects.
As a result, according to a study in the August issue of Annals of Epidemiology, a large number of women who used hormone replacement therapy may have been at increased risk -- and women who continue to use "unopposed" estrogen replacement remain at risk -- for developing heart problems.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
