The world is seeing the human cost of climate disruption playing out across the Horn of Africa. Severe droughts, erratic rainfall and rising temperatures have tipped nations towards famine and left communities fighting for survival. But it's also a man-made crisis and one that we can address both in the short and long term reports Joe Ware.

Researchers from Nipissing University’s Geography department are part of a study published in the journal Marine and Freshwater Research that points a finger at climate change as the cause of a massive wetland die-off in Australia.

Stars don't have to be massive to evaporate material from around nearby stars and affect their ability to form planets, a new study suggests.

Effects of livestock grazing on greater sage-grouse populations can be positive or negative depending on the amount of grazing and when grazing occurs, according to research published today in Ecological Applications. The research was conducted by scientists from the United States Geological Survey, Colorado State University and Utah State University.

Mercury is very toxic and can cause long-term health damage, but removing it from water is challenging. To address this growing problem, University of Minnesota College of Food, Agricultural and Natural Sciences (CFANS) Professor Abdennour Abbas and his lab team created a spongethat can absorb mercury from a polluted water source within seconds. Thanks to the application of nanotechnology, the team developed a sponge with outstanding mercury adsorption properties where mercury contaminations can be removed from tap, lake and industrial wastewater to below detectable limits in less than 5 seconds (or around 5 minutes for industrial wastewater). The sponge converts the contamination into a non-toxic complex so it can be disposed of in a landfill after use. The sponge also kills bacterial and fungal microbes.
