A Mysterious Desert Bacterium Has Evolved Its Own, Unique Ability to Photosynthesize

Photosynthesis quite literally changed our world. Plants ‘eating’ sunlight and ‘breathing out’ oxygen transformed Earth’s entire atmosphere into the one we now breathe, and fuel our ecosystems with energy.   Now researchers have caught a cunning species of bacteria with stolen photosynthesizing technology. And their molecular, light-eating device is unlike any we’ve ever seen. “The … Read more

Prehistoric Volcanoes Heated Earth in a Global Chain Reaction

Climate experts have warned for decades of “tipping points” at which modern global warming might cause a cascade of accelerating, irreversible effects. Now geologists are beginning to identify similar junctures in the fossil record. For example, around 56 million years ago—when our small primate ancestors still hopped through the trees—volcanic eruptions may have sparked hothouse … Read more

There’s a Cancer Treatment That Gives People ‘Night Vision’. Here’s How

Among all the different types of cancer treatment, photodynamic therapy – where light is used to destroy malignant cells – might have one of the strangest side effects: Patients are often better able to see in the dark.   Last year, researchers finally figured out why this happens: Rhodopsin, a light-sensitive protein in the retinas in our eyes, interacts with … Read more
