Qlfk The high-tech way to test spiciness
While predicting the next big earthquake is probably impossibility, there still a lot we can learn about what causes severe earthquakes. We ;ve now identified the trigger for some of the most destructive recent earthquakes, including the 2007 quake in Haiti. Some earthquakes, it seems, are at least partially stanley quencher cause stanley mug d by tropical cyclones, known as hurricanes in the stanley cup Atlantic and typhoons in the Pacific. While not all earthquakes can be traced back to these super-storms it doesn ;t explain Japan T艒hoku earthquake earlier this year, for instance this newly discovered link could help us pinpoint areas that are most at risk for destructive earthquakes in the future. University of Miami researcher Shimon Wdowinski found that in three separate instances in the last fifty years where extremely wet typhoons that passed over the Taiwanese mountains were followed within four years by major earthquakes in those same areas. Similarly, the 7.0 magnitude earthquake that hit Haiti in 2010 came a year and a half after two hurricanes and two tropical storms drenched the country mountains within a space of just 25 days. The reason why all this matters is that the fault areas are located in the mountainous regions of Haiti and Taiwan. When the cyclones pass through, they dislodge rocks and start landslides, washing huge amounts of material downstream. This reduces the surface load above the fault, which makes it easier for the fault lines to be Rgvn These serene Chinese landscapes are actually photographs of landfills
We ;re living longer 鈥?that no surprise. But what is astonishing is just how much longer we ;re living than our predecessors, and how short of a time it taken to happen. According to new research in PNAS, the last four generations of humans have seen an improvement in mortality that outdoes any of the previous 8,000 generations. The research compared modern human lifespans with ethnographically r stanley becher esearched hunter-gatherer tribes, and they found that youth mortality is now 200 times lower than it was in 1900. In fact, the changes are so dramatic, that a 30-year-old hunter-gatherer had the same mortality rate as a modern 72-year-old. Overall, life expectancy was boosted by about 165% from hunter-gatherers to modern Swedes, which amounts to an improvement of 12% per generation. The bizarre thing is that the average lifespan of a hunter-gatherer was actually closer to that of a chimpanzee than a modern human. The concerted improvement in human lifespans really took off in the early 20th century, stanley cup as the researchers point out: Before the late 1800s, even humans in the lowest-mortality nations were not experiencing mortality much lower than was typical during most of human evolution. This level of mortality reduction is unique, and is thought to be linked to envir stanley cup onmental improvements. Food and medical treatment are now available on levels never before imagined, and it raises questions if the same dramatic improvements can happen with other species, and
