This is the approach of two leading candidates for a quantum theory of gravity, string theory and loop quantum gravity. But a new theory challenges that consensus and takes an alternative approach by suggesting that spacetime may be classical -- that is, not governed by quantum theory at all.  Mon, 04 Dec 2023 13:51:56 EST https://www.sciencedaily.com/releases/2023/12/231204135156.htm Decades after blood pressure-related pregnancy complications, women can have changes in heart structure and function https://www.sciencedaily.com/releases/2023/12/231204135150.htm Hispanic/Latina women with a history of hypertensive disorders of pregnancy (HDP) -- conditions marked by high blood pressure during pregnancy -- are more likely to have abnormalities in their heart structure and function decades later when compared with women without a history of HDP, according to a new study. The findings also suggest that while having high blood pressure later in life can contribute to these abnormalities, HDP play the greater role, significantly raising a woman's risk of developing cardiovascular disease.

Mon, 04 Dec 2023 13:51:12 EST https://www.sciencedaily.com/releases/2023/12/231204135112.htm Endovascular catheter opens blocked arteries deep within lungs https://www.sciencedaily.com/releases/2023/12/231204135110.htm A new endovascular catheter, recently approved by the U.S. Food and Drug Administration (FDA), is paving the way to more effective and safe treatment for acute pulmonary embolism. Already shown to be effective for reducing blockages in lung arteries, new research shows that this catheter also reduces blockages in the smaller segmental pulmonary artery branches. These branches are ultimately responsible for oxygenating the blood in the lungs. The new study, which was part of the National Institutes of Health-sponsored multicenter RESCUE clinical trial, further showed a correlation between decreased numbers of blockages in the small lung arteries and functional recovery of the right ventricle of the heart, which pumps blood into the main pulmonary artery of the lungs. Compared to other devices, the BASHIR™ catheter also had significantly lower bleeding rates, a key advance in acute pulmonary embolism treatment. The findings are described in JACC: Advances.
