When did air pollution first appear in South America? Apparently, it was present even during the 16th century. Researchers have discovered remnants of air pollution in the Quelccaya Ice Cap, revealing a bit more about the past history of the region.
Harvesting sunlight is a trick that plants have mastered. Now, scientists have created a system that also uses sunlight. The technique has the ability to use bacterial to convert solar energy to liquid fuel.
Floods are becoming more frequent in the Midwest. Scientists have found that the U.S. Midwest and surrounding states have endured increasingly more frequently flood episodes over the past 50 years.

Most people know that our planet Earth has a core; but did you know that the core has a core? Seismic waves are helping scientists plumb the depths of our planet and have shown that the Earth actually has an inner core.
Swimming reptiles have made their mark in the Triassic. Scientists have taken a look at early Triassic deposits and have found that they contain the highest number of fossil swim track occurrences worldwide compared to other epochs.
A new initiative may be key to measuring the impact of climate change on thunderstorms. Scientists have created a draft of a global thunderstorm map, which could be crucial when it comes to storm prediction in the future.
Lungfish and salamanders can hear, despite not having an outer ear or tympanic middle ear. Now, scientists are taking a closer look at exactly how hearing evolved about 300 million years ago.
When it comes to eating healthy, you may want to go organic. Scientists have taken a look at a person's pesticide exposure as part of a healthy diet, and have found that going organic may help reduce this particular exposure.
It turns out that some ancient snow patches which have existed for thousands of years are now melting at record speeds. Scientists have found that glaciers and permanent snow patches in Norway are now vanishing at an astonishing rate.
Previous research has shown that the disappearance of Neaderthals (Homo neaderthalensis) from Europe occurred an estimated 40,000 years ago. Yet new research reveals that these hominids could have disappeared near the Iberian Peninsula just about 45,000 years ago.
