8:46 PM | A clear, molecular view of the evolution of human color vision
By around 30 million years ago, our ancestors had evolved the ability to see the full-color spectrum of visible light, except for UV.By Carol ClarkMany genetic mutations in visual pigments, spread over millions of years, were required for humans to evolve from a primitive mammal with a dim, shadowy view of the world into a greater ape able to see all the colors in a rainbow.Now, after more than two decades of painstaking research, scientists have finished a detailed and complete picture of the […]

3:04 PM | The Next New Species Could be in Your Backyard: Why Exploration and Discovery Matter – Everywhere
Gregory M. Mueller, Ph.D. Chief Scientist and Negaunee Foundation Vice President of Science Chicago Botanic Garden When we think about discovering new species, we tend to envision tropical rainforests, remote deserts or lofty mountain peaks.

12:39 PM | Three Conservation Success Stories
With rising sea levels, continued deforestation of the rainforests, and an ever-increasing list of animals at risk of endangerment or extinction, a casual observer of today’s media would not be at fault for presuming that the state of our world ecosystem is all doom and gloom. Yet for every disappeared species, every illegal logging project in the Amazon, there is another story of success by conservationists around the world. These stories are often underplayed and under-appreciated by […]

8:29 PM | Watch As 40-Foot Trees Are Swallowed Up In Seconds By An Underwater Sinkhole (Video)
Last summer, a massive sinkhole opened up underneath the Corne Bayou in Assumption Parish, Louisiana. The bayou sits above an old salt mine that is slowly collapsing. On August 3, 2012, a one-acre sinkhole opened up, prompting Louisiana mayor Bobby Jindal to order an evacuation of the small Bayou Corne community. In just a single year, the sinkhole expanded in size from one to 28 acres. According to ecology.com, “In places, it is estimated to be 750 feet deep, and some […]
