In the remote community of Fort Severn, a man showed incredible courage when he leaped onto a polar bear to protect his wife. The attack happened early Tuesday morning. The bear was in their driveway and lunged at the woman, causing her to fall. Her husband quickly jumped on the bear to stop it. Sad
Ever heard of cover crops? They're like the superheroes of farming, fighting climate change one field at a time. Unlike the usual crops we know, cover crops are grown when the main crops aren't there. They do something amazing – they suck up carbon from the air and store it in the soil. This helps t
Composting is a smart way to recycle waste, but it often loses nitrogen, which is bad for the process. Biofiltration, a new method, can catch and change gaseous emissions into something useful. A recent study looked into how well a system that combines composting and biofiltration could keep nitroge
China has been on a mission to get more plug-in hybrid electric vehicles (PHEVs) on its roads. The idea is to cut down on carbon dioxide (CO2) emissions by using electricity instead of gas. But does this plan really work? Researchers looked into this from 2016 to 2020. They found that swapping a reg
Picture this: cleaning up oil wastewater in a simpler way. Typically, you'd use two methods - adsorption and flotation. But scientists in Brazil decided to combine these into one. They created a special material called biochar and tested it on real oil wastewater from local wells. This new method pr
Earth's atmosphere is heating up, and methane (CH₄) is a big reason why. This potent greenhouse gas is responsible for about one-fifth of the global temperature increase since the preindustrial era, trailing only behind carbon dioxide (CO₂). Over the last five decades, human-caused methane emissions
Imagine a world where running, climbing, swimming, and diving aren't just sports or hobbies, but essential skills for daily survival. This is the reality for many hunter-gatherer communities worldwide. Over 900 ethnographic records highlight the amazing adaptability of these societies. Both men and
Imagine you're on an island, and the climate is getting warmer. Over time, certain birds might move in or out, shifting the bird community. Now, consider that the same island could be big or small, or close to others. Researchers found that on smaller or more isolated islands, warm-loving birds move
Water is a big deal in Vietnam, especially for farmers. A new study in the Mekong Delta shows laser land leveling (LLL) can save a lot of water. Farmers using LLL can save up to 20% more water compared to traditional methods. That’s like having more water for everyone! But is it all sunshine and ra
Oil spills are a big problem for our planet's water bodies. They hurt marine life and can last for a long time. People have been trying different ways to clean them up, like physical methods, heating, using living organisms, and chemicals. But these don't always work well. Chemical dispersants are p
