...edge of the universe, two stars the size of Earth, made of million-degree diamond and oxygen, smash together in an explosion that outshines their entire galaxy. The shrapnel from explosions like that one are thought to have made everything we know on Earth—including us—and could provide clues to the ultimate fate of the universe. And last week, a team led by Harvard astronomers announced they had seen such shrapnel. What the team observed was a stellar explosion, called a supernova, that was caused by the merger and collision of two white dwarf stars?...
...boarded the Airbus A300 owned by former Indian Airlines engineer B.C. Gupta. Take, for example, the safety demonstration. After asking for a volunteer from the 120 or so kids crammed, some two to a seat, in the plane's economy-class cabin, flight attendant Ridhi Sehgal explains how the oxygen masks work. A plastic deck chair appears and Sehgal helps the volunteer, a worried-looking boy of 7, up onto it so that the other passengers can see him. "This is just for show," Sehgal explains. "You don't have to stand on your chair; the oxygen will drop down...
...says Jake Colvin, director of USA Engage in Washington, which favors moves like lifting the ban on U.S. travel to Cuba - something even most Cuban-Americans in Miami now favor, and which many Cuba watchers suggest the Castros actually fear. Bush insisted that engaging Cuba now would just give "oxygen to a criminal regime." But, argues Colvin, "American citizens have always proven the best ambassadors of freedom and democracy...
...responsible for this added risk, those percentages had already been disturbing enough to persuade physicians to change what is known as their transfusion trigger. As a rule, they introduced donated blood as soon as the patient's hematocrit--a measure of the proportion of the blood made up of oxygen-carrying red cells--fell below the normal range of 45%-55%. Lately, however, they have begun waiting until it drops to less than 30% before transfusing...
...blood that's on the shelves. Working with dogs, Stamler has shown that the heart-attack rate drops when depleted blood is replenished with liquid NO. Human premature babies born with underdeveloped lungs are already being exposed to gaseous NO to help their tissues get the oxygen they need. For now, the American Red Cross, which oversees the 14 million units of stored blood, is awaiting more studies before changing its processing and storage practices...
