There is little dispute that in the wake of European colonists’ arrival in the New World, Native American populations were decimated by disease and conflict. But when it comes to the timing, magnitude, and effects of this Native American depopulation — it depends on who you ask. Many scholars claim that disease struck the native population shortly after their first […]

Stare out upon the ocean at sunset and you can almost convince yourself that all is well beneath the surface. Sadly, the exact opposite is very true. Three new studies reveal just how sick the oceans are, as well as just how big a role humans are playing. Let’s begin with climate change: according to a report from NASA and […]

Over 15 years of observational data collected by NASA’s Chandra X-Ray Observatory and the Australia Telescope Compact Array have given us a composite image of a tremendous cosmic blast. The image depicts an x-ray beam (blue) casts away from the black hole sitting at the center of Pictor A, a galaxy located 500 million light years from Earth. Other prominent […]

Climate change may have helped to alter the course of history. A period of extreme and unprecedented cooling in the northern hemisphere 1,500 years ago may have reduced the eastern Roman empire, set the stage for a famine and a devastating pandemic that killed millions, and favored the rise of the Islamic forces that created the Arab empire. The so-called Little […]

The newest professor in the University of Rhode Island’s College of the Environment and Life Sciences, Hollie Putnam, thinks some corals and shellfish might have good enough “memories” to buffer the changes in ocean chemistry that are resulting from the effects of climate change on coral reefs. A native of Minnesota who earned a doctorate at the University of Hawaii, […]

“Colony collapse disorder” the mysterious, decade-long die-off among honeybees, is getting worse. A survey of about 5,000 beekeepers in the U.S. has found that they’ve lost about 42 percent of their colonies over just the past year. Even more alarming is the fact that honeybee deaths spiked in the summer, when bees are usually healthiest. “What we’re seeing with this […]

Climatologists have started to drill into the oldest ice core in Antarctica to find some air that may have been there around 1 million to 900,000 years ago. The teams are from Australia, China, and Europe in a friendly type competition to find samples of air that is about 1.5 million years old. They would like to find out what […]

WASHINGTON, D.C. During a press conference last month, NASA released a slew of odd sound recordings and video from the Messenger probe just moments before it’s impact on Mercury. Scientists are working to decipher the meaning of the data, but some agree that the recordings sound like human voices crying out in agony. The Messenger probe had been orbiting Mercury […]

The year 1934 was a very hot year in the United States, ranking fourth behind 2012, 2006, and 1998. However, global warming takes into account temperatures over the entire planet. The U.S.’s land area accounts for only 2% of the earth’s total surface area. Despite the U.S. heat in 1934, the year was not so hot over the rest of […]

Climate change is killing off Bees In India. A lethal combination of climate change and human interference is helping to wipe out colonies of the giant honeybees on which many plants and trees in India depend for their survival. The precise cause of colony collapse disorder (CCD) is not known, but researchers say that the loss of the bees will […]
