Experts have also questioned the wisdom of erecting more concrete defenses in a country that has dammed most of its major river systems and fortified entire shorelines with breakwaters and concrete blocks. Some of these protections, they say, only encourage development in regions that could still be vulnerable to future flooding. In eastern Saitama, where the Kasukabe facility has done the most to reduce floods, local industry has flourished; the region has successfully attracted several large e-commerce distribution centers and a new shopping mall. Still, the Kasukabe operation remains a critical part of Tokyo's defenses, say officials at Japan's Land Ministry, which runs the site. Five vertical, underground cisterns, almost 250 feet deep, take in stormwater from four rivers north of Tokyo. A series of tunnels connect the cisterns to a vast tank, larger than a soccer field, with ceilings held up by 60-foot pillars that give the space a temple-like feel. From that tank, industrial pumps discharge the floodwater at a controlled pace into the Edo river, a larger river system that flushes the water into Tokyo Bay.
In the Science study, researchers examined plots of soil in the Harvard Forest in Massachusetts, a mixed hardwood forest in the U.S. They experimented by heating some of the plots with underground cables to 5C above normal levels, leaving others as a control. The long-term study revealed that in the first 10 years there was a strong increase in the carbon released from the heated plots, then a period of about seven years when the carbon release abated. But after this second calmer period, which the scientists attribute to the adjustment of the soil microbes to the warmer conditions, the release of carbon resumed its upward path. From 1991, when the experiment began, the plots subjected to 5C warming lost about 17% of the carbon that had been stored in the top 60cm of the soil, where the greatest concentration of organic matter is to be found...
Lead scientist Jerry Melillo, points out that currently 10 billion metric tons of carbon gets released into the atmosphere every year, but "The world's soils contain about 3,500 billion tons of carbon. If a significant amount of that is added to the atmosphere, due to microbial activity, that will accelerate the global warming process. Once this self-reinforcing feedback begins, there is no easy way to turn it off. There is no switch to flip."
Our space agencies won't be able to push out farther into space, to a destination like Mars, until we can learn more about how to strengthen the weakest links in the chain that make space flight possible: the human body and mind... [V]ery little is known about what occurs after month six. The symptoms may get precipitously worse in the ninth month, for instance, or they may level off. We don't know, and there is only one way to find out... On my previous flight to the space station, a mission of 159 days, I lost bone mass, my muscles atrophied, and my blood redistributed itself in my body, which strained and shrank the walls of my heart. More troubling, I experienced problems with my vision, as many other astronauts had. I had been exposed to more than 30 times the radiation of a person on Earth, equivalent to about 10 chest X-rays every day. This exposure would increase my risk of a fatal cancer for the rest of my life.
Kelly says the Space Station crew performed more than 400 experiments, though about 25% of his time went to tracking his own health. "If we could learn how to counteract the devastating impact of bone loss in microgravity, the solutions could well be applied to osteoporosis and other bone diseases. If we could learn how to keep our hearts healthy in space, that knowledge could be useful on Earth." Kelly says he felt better a few months after returning to earth, adding "It's gratifying to see how curious people are about my mission, how much children instinctively feel the excitement and wonder of space flight, and how many people think, as I do, that Mars is the next step... I know now that if we decide to do it, we can."
Yesterday, a group of five publishers -- ACS, Elsevier, Brill, Wiley and Wolters Kluwer -- announced that ResearchGate had rejected the association's proposal. Instead, the group, which calls itself the "Coalition for Responsible Sharing," said in a October 5th statement that ResearchGate suggested publishers should send the company formal notices, called "takedown notices," asking it to remove content that breaches copyright. The five publishers will be sending takedown notices, according to the group. But the coalition also alleges that ResearchGate is illicitly making as many as 7 million copyrighted articles freely available, and that the company's "business model depends on the distribution of these in-copyright articles to generate traffic to its site, which is then commercialized through the sale of targeted advertising." The coalition also states that sending millions of takedown notices "is not a viable long-term solution, given the current and future scale of infringement Sending large numbers of takedown notices on an ongoing basis will prove highly disruptive to the research community." As a result, two coalition members -- ACS and Elsevier -- have opted to go to court to try to force ResearchGate's hand.
Scientists also now think that differences in hair color, mood and whether someone will smoke or have an eating disorder could all be related to inter-breeding, after comparing ancient DNA to 112,000 British people who took part in the UK Biobank study. The Biobank includes genetic data along with information on many traits related to physical appearance, diet, sun exposure, behavior, and disease and helps scientists pick apart which traits came from Neanderthals. Dr Janet Kelso, of the Max Planck Institute for Evolutionary Anthropology, in Germany, said: "We can now show that it is skin tone, and the ease with which one tans, as well as hair color that are affected."
One way of looking at it is that when he was designing his categories, he wanted the prizes to only reflect advances in fundamental science. In this view, "lesser" sciences such as biology, geology, or computer science -- or technology-driven fields such as engineering or robotics -- don't qualify. As genome-sequencing pioneer Eric Lander once said, "You don't get a Nobel Prize for turning a crank." But what then of literature and peace, or the newer prize for economics (an applied science at best, and a pseudoscience at worst)? Technology isn't the only field to get the cold shoulder. Mathematics -- the international language, the foundation of so many scientific pursuits, and arguably the most fundamental theoretical discipline of all -- doesn't have a Nobel Prize, either. Mathematicians have complained about this for decades. One story suggests that Nobel disliked the Finnish mathematician Rolf Nevanlinna, and assumed that he would be the first winner of the mathematics prize, if he decided to award one. Alternatively, math undergraduates are often told that Nobel was jealous of a Swedish mathematician who had an affair with his wife (though this story is ruined by the fact that Nobel didn't actually have a wife).
