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 […]

New research suggests that high levels of BPA, a chemical in many plastics and canned food linings, might raise the risk of miscarriage in women prone to that problem or having trouble getting pregnant. While the study is not nearly enough to prove a link, experts say it does add to “the biological plausibility” that BPA might affect fertility and […]

While the Quebec Environment Minister David Heurtel has stated that the sewage dump […]

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 […]

Researchers have discovered a new map of the octopus genome that is so strange that it could actually be an “alien”. The first whole cephalopod gene sequence shows a striking level of complexity with 33,000 protein-coding genes identified – more than in a human. Not only that, the octopus DNA is highly rearranged – like cards shuffled and reshuffled in […]

Feeling itchy from a sunburn, a bug bite or some other skin irritation is miserable, but the pleasure you get from scratching it isn’t just the absence of pain. It feels legitimately good to scratch, and the reason is fascinating. A 2008 study at Wake Forest University hooked people up to a MRI scanner and monitored brain activity when they […]

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 […]

Training for a marathon and other extreme workouts may be more harmful than healthy. After reviewing over 50 studies, researchers at the Mayo Clinic found that more than an hour of intense aerobic activity per day put runners and cyclists at heightened risk of serious heart problems, including an irregular heartbeat, clogged arteries, and scarring. Habitual marathon runners and professional […]
