Library of alexandria. Dino-era Mammal the "Jurassic Mother" of Us All? A tiny, shrew-like creature of the dinosaur era might have been, in a sense, the mother of us all.
Named the "Jurassic mother from China" (Juramaia sinensis), the newfound fossil species is the earliest known ancestor of placental mammals—animals, such as humans, that give birth to relatively mature, live young—according to a new study. The 160-million-year-old specimen pushes back fossil evidence for the evolutionary split between the placental and marsupial lineages by 35 million years. Homo Erectus travelled the high seas. Early manlike creatures may have been smarter than we think.
Recent archaeological finds from the Mediterranean show that human ancestors traveled the high seas. A team of researchers that included an N.C. State University geologist found evidence that our ancestors were crossing open water at least 130,000 years ago. That's more than 100,000 years earlier than scientists had previously thought.

When We Tested Nuclear Bombs -- Earth Changes. Since the time of Trinity -- the first nuclear explosion in 1945 -- nearly 2,000 nuclear tests have been performed, with the majority taking place during the 1960s and 1970s. When the technology was new, tests were frequent and often spectacular, and led to the development of newer, more deadly weapons.
But starting in the 1990s, there have been efforts to limit the future testing of nuclear weapons, including a U.S. moratorium and a U.N. comprehensive test ban treaty. As a result, testing has slowed -- though not halted -- and there are questions about the future. Who will take over for those experienced engineers who are now near retirement, and should we act as stewards with our enormous stockpiles of nuclear weapons? What happened in my birth year?
