Researchers looked at x-ray novae, which are pairs of stars that rotate quickly and very close to each other. One of the stars in an x-ray nova is a normal star, like the sun, and the other one is a dense, compact star...
...some x-ray novae, the dense star is a neutron star. In these situations, gas and other matter flow away from the normal star and eventually collide with the surface of the neutron star--causing an explosion that releases a bright burst of energy...
...back on salt or sodium can help lower blood pressure in folks with hypertension, a silent condition that increases the risk of heart attack and stroke. What hasn't been so clear is whether reducing the amount of sodium in the diet will benefit those whose blood pressure is normal. Now comes word that restricting salt can indeed lower normal blood-pressure levels. Though the effect isn't as great, it's still important, according to a study published in last week's New England Journal of Medicine...
Reviewers and critics dubbed Carver and his epigones Minimalists, a term the author disliked. His reasons for doing so extended beyond the normal artistic resentment at being pigeonholed. Carver knew, as others have discovered in the past few years, that heavy excisions were performed on his early stories by Gordon Lish, a fiction editor at Esquire in the '70s and then at Knopf during the preparation of What We Talk About When We Talk About Love. That book, with 17 terse stories crammed into 159 pages, solidified Carver's reputation but left him feeling that he had ceded too much...
...obesity rolling, and it was Friedman's research team that was responsible. Studying the genome of a rare strain of hugely obese mice, the investigators found that all of them shared a defect in a gene that coded for a previously unknown hormone released by body fat. When a normal animal gains too much weight, the hormone signals the brain to turn down the appetite rheostat. When fat stores drop, the hormone is shut off, causing appetite to rebound. In the gene-damaged mice, there was no leptin at all, causing them to eat and eat without satiation. "We called...
