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. Homo Erectus travelled the high seas. Early manlike creatures may have been smarter than we think.

Homo Erectus travelled the high seas

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. Their evidence is based on stone tools from the island of Crete. Human rights & democracy statistics.

He also shows the surprisingly weak correlation between existing estimates for democracy and socio-economic progress. The reason may be that democracy and human rights measurements are badly done. It may also be that democracy and human rights are dimensions of development that are in themselves difficult to assign numerical values. But it also seems as much improvement in health, economy and education can be achieved with modest degrees of human rights and democracy.

They have not been officially valued and inspectors are taking an inventory.

King 2012Gospel of Jesus' Wife: front. The Gospel of Jesus' Wife, a papyrus fragment of Coptic script containing a suggestion that Jesus may have been married, is an ancient document, and not a modern forgery, says a paper published in the Harvard Theological Review on Tuesday. Tests by teams of engineering, biology, and chemistry professors from Columbia University, Harvard University, and MIT indicate the papyrus dates to between the sixth and ninth centuries, and possibly as far back as the second to fourth centuries. When We Tested Nuclear Bombs. 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 We Tested Nuclear Bombs

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. What happened in my birth year?
