...interests. Mukhopadhyay says he remembers his interest in noble gas geochemistry being piqued as a graduate student at the California Institute of Technology. An advisor was using the interplanetary dust particles that have been settling on the Earth’s surface throughout its history as a way to reconstruct past variations in climate. They found that helium-3—a rare noble gas isotope that is extremely depleted on Earth—proved to be a good tracer for the dust particles. “If you imagine material from space is raining down at a constant rate...
...Consider: almost half of China's $585 billion economic-stimulus program, announced last November to much fanfare, is earmarked for infrastructure spending on railroads, highways and power grids. Another 25% will go to reconstruct entire towns in Sichuan province that were devastated by last year's earthquake. These are "shovel-ready" infrastructure projects, and financial markets rallied on March 4 partly due to expectations - unfounded, as it turned out - that Chinese Premier Wen Jiabao would unveil a second round of stimulus measures on March 5 during the opening of China's annual National Party Congress in Beijing.

...which he therefore had to destroy.”“The Conqueror” is a pleasant, easy read since it’s broken up into convenient and short chapters. The plot is divided into short scenes in Jonas’ life that attempt to reconstruct and represent the person he has become. The order of these scenes—neither chronological nor under the sway of any organizing voice—and the degree to which each story is important to the novel’s framework are both arbitrary. Unfortunately, a handful of these sections...
...Marquis places the urn in a large ziplock bag and labels it with the date and exact location of the find. Once the dig is finished, all the artifacts will be shipped to Kabul where they will be analyzed and placed in a historical context, enabling the archaeologists to reconstruct what life once looked like at Tepe Zargaran. "We never knew this was important before," says Basir. "Now, when I find something like this, I am happy. A part of my history comes alive...
Darwin had no way of knowing this, since he had no way of examining DNA. If he did, he might well have rethought one of his most potent metaphors for evolution: the tree of life. It's not that the metaphor is wrong. Scientists regularly reconstruct evolutionary branches today. When a new disease breaks out, for example, the fastest way to figure out what to do is to determine what the pathogen is related...
