...accept only low-risk patients, which excludes women with diabetes, high blood pressure, multiple births or any other risky condition. Most midwives--who typically charge from $1,000 to $5,000 per birth, significantly less than the cost of a hospital delivery--travel with basic emergency medical equipment, including oxygen, resuscitation gear and medication to stop hemorrhaging. And all insist they practice preventively and know when--and how--to get a woman to a hospital...
...atmosphere when it accumulated as snow. They can tell how much carbon dioxide was in the air during a given time period (roughly seven years with each layer, because in the porous firn - unlike the frozen ice below - air from different years can mix over time), and by analyzing oxygen isotopes inside the firn, they can tell the temperature as well. Johnsen and Hansen bring a core to surface, through a hole 60 m deep - it's a bit like ice fishing. What comes out of the driller is brilliant and glistening in the Arctic sunlight, crystalline. It's solid...
...sheet and will, as the name suggests, drill. The ice in central Greenland is nearly 3 km thick, and as you drill down to the bottom, you can read the climatic history of the island as if you were counting tree rings going back tens of thousands of years. Oxygen isotopes trapped in the ice core can tell you what the temperature was in a given year; trapped air bubbles can reveal how much carbon dioxide and other gases were in the atmosphere at a particular time. You can even trace impurities that were in the air during the Roman...
Investigators studying last week's explosion aboard Qantas Flight 30 believe a burst oxygen tank, and not a bomb, was responsible for the blast and forced emergency landing in Manila. The explosion ripped a 9-foot hole through the side of a Qantas Boeing 747 - and an even bigger hole in the airline's reputation. In its 88-year history, the Australian carrier has had no fatal accidents and only three previous "major safety events." But that record ensures that even small incidents make headlines. Since 2006 there have been a growing list of such relatively minor mishaps: burst tires...
...substance that is the basic building block of life as we know it - without it, our planet might be little more than a dull rock - carbon has gotten a bad rap lately. Bound to two atoms of oxygen, it creates carbon dioxide, the chief greenhouse gas that has kept our planet warm for billions of years - and is now, thanks to human activity, making us too warm. When we think of carbon, the first word we associate with it is emissions, a concept that evokes a tinge of illegality, as if emitting a mere molecule of CO2 were a crime...
