Each summer, more and more lake beaches are forced to close due to toxic algae blooms. While climate change is often blamed, new research suggests a more complex story: climate interacts with human activities like agriculture and urban runoff, which funnel excess nutrients into the water. The study sheds light...

Researchers demonstrated that brewing tea naturally adsorbs heavy metals like lead and cadmium, effectively filtering dangerous contaminants out of drinks. Researchers tested different types of tea, tea bags and brewing methods. Finely ground black tea leaves performed best at removing toxic heavy metals. Longer steeping times helped tea remove larger...

Crab behavior suggestive of wound-tending may improve coral tolerance to heat waves.

There's an arms race in medicine -- scientists design drugs to treat lethal bacterial infections, but bacteria can evolve defenses to those drugs, sending the researchers back to square one. A team describes the development of a drug candidate that can stop bacteria before they have a chance to cause...

This research comes as dengue-carrying mosquitoes expand their territory into new regions, including Southern California.

Remember when 2 degrees Celsius of global warming was the doomsday scenario? Well, we're now staring down the barrel of something much worse. From the fish on your plate to the weather outside your window, everything's about to change. A new study underscores the grave risks posed by insufficient national...

It is no strange sight to see icebergs break off of the Antarctic ice cap and drift away, like the gigantic sheet of ice that is currently heading for the island of South Georgia. But climate change is making it happen more frequently, with ever-larger icebergs in the waters around...

The gut bacteria of giraffes are not primarily determined by what they eat, but by the species they belong to. This is shown in a new study in which researchers have analyzed the link between diet and gut flora in three giraffe species in Kenya. The study also provides new...

New analysis of ancient fossilized rocks known as stromatolites, preserved in southern Zimbabwe, suggests strong links to hydrothermal nutrient recycling, 'meaning that early life may in part have been fueled by volcanic activity'.

Agricultural fertilizers are critical for feeding the world's population, restoring soil fertility and sustaining crops. Excessive and inefficient use of those resources can present an environmental threat, contaminating waterways and generating greenhouse gases such as nitrous oxide. Now, researchers have addressed those challenges with glass fertilizer beads. The beads control...
