Ye olde pathogen: Learning about evolution from ancient DNA
As long as humans have been around, there have been pathogens to make us sick. Some have achieved infamy in human history—the bubonic plague, for example, or smallpox—and with modern technologies, scientists can time-travel to find out what the b.....»»
In search of evidence of ancient human existence, researchers traverse the inhospitable Namib desert
Strewn across the Namib desert is a treasure trove of stone tools of which little is known because getting to them is so difficult. There are few roads and vehicles have limited access in this protected area that lies in the desert of western Namibia.....»»
Astronomers detect ancient lonely quasars with murky origins
A quasar is the extremely bright core of a galaxy that hosts an active supermassive black hole at its center. As the black hole draws in surrounding gas and dust, it blasts out an enormous amount of energy, making quasars some of the brightest object.....»»

DNA confirms these 19th-century lions ate humans
“Tsavo Man-Eaters” killed dozens of people in late 1890s, including Kenya-Uganda Railway workers. For several months in 1898, a pair of male lions turned the Tsavo region of K.....»»
Plate tectonics drive compositional evolution of the upper mantle, study finds
On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied. However, when did global chemical heterogeneity of the conv.....»»
Hubble captures intricacies of R Aquarii, a symbiotic binary star roughly 700 light-years from Earth
The NASA/ESA Hubble Space Telescope has provided a dramatic and colorful close-up look at one of the most rambunctious stars in our galaxy, weaving a huge spiral pattern among the stars. Hubble's images capture its details and its evolution is featur.....»»
