Sean Carroll: The multiverse might be impossible to test directly. Even if such a theory were true, the worry goes, how would we ever know? Is it scientific to even talk about it?
One of the primary forces behind climate change-driven sea level rise is the Greenland Ice Sheet. Covering 80% of Greenland, it’s the world’s second-largest chunk of ice (after the Antarctic Ice Sheet) and dumps 240 billion tons of fresh water into the oceans every year, accounting for a full fifth of annual sea level rise….
Natural fluctuations alone do not explain warming in the upper layers of the planet’s oceans, confirms a new computer modeling study. The ingredient necessary to fully account for rising water temperatures in the last 50 years? Humans’ greenhouse gas emissions. While attributing global warming to humans is hardly a new conclusion, this study adds to…
Critics claim that evolutionary biology is, at best, guesswork. The reality is otherwise. Evolutionists have nailed down how an enormous number of previously unexplained phenomena—in anatomy, physiology, embryology, behavior—have evolved. There are still mysteries, however, and one of the most prominent is the origins of homosexuality. The mystery is simple enough. Its solution, however, has…
Chimpanzees have made headlines in recent years for several unprovoked attacks against humans, the latest just recently at the Jane Goodall Institute Chimpanzee Eden in South Africa. The severely injured victim, University of Texas graduate student Andrew Oberle was mauled by chimpanzees as he gave a lecture to about a dozen tourists. Oberle remains in…
Poisoned-tipped arrows and jewelry made of ostrich egg beads found in South Africa show modern culture may have emerged about 30,000 years earlier in the area than previously thought, according to two articles published in the journal Proceedings of the National Academy of Sciences. The research shows that the 44,000-year-old artifacts are characteristic of the…
Just as species are thought to have evolved over time, the individual molecules that form the basis of life also likely developed in response to natural selection, scientists say. Life on Earth first bloomed around 3.7 billion years ago, when chemical compounds in a “primordial soup” somehow sparked into life, scientists suspect. But what turned…
