  • An ancient people with a modern climate plan

    The Swinomish tribe in Washington state is combining traditional knowledge and science to combat the effects of climate change and improve the health of its land, water, and people. In recent years, their salmon harvest has diminished due to warming waters, but they’ve instituted salmon recovery efforts by restoring tidelands and channels and planting trees along stream beds to cool the waters. Their focus on ecosystem and community health could be a model for other Indigenous tribes looking to create their own climate plans.

  • Pee fanatics want to feed the world with your liquid gold Audio icon

    A French startup is turning urine into an environmentally-friendly fertilizer that could replace chemical products. Early tests suggest that the urine mixture created by Toopi Organics can compete with synthetic fertilizers, which end up in waterways and can alter lake and river ecosystems. While the organic fertilizer requires a significant amount of urine to make, it could be a viable alternative to grow crops.

  • The daring plan to save the Arctic ice with glass Audio icon

    The nonprofit Arctic Ice Project is testing an unusual approach to combat climate change: by scattering a thin layer of reflective glass powder over parts of the Arctic. By putting this material on top of the ice, they’re studying if the powder can protect the ice during the summer months and rebuild it over time. In one pond in Minnesota, just a few layers of the material made young ice 20 percent more reflective and delayed the melting of the ice. Other scientists question the impact the material can have on the Arctic ecosystem, but the approach could be a way to counteract the effects of global warming.

  • India's first two ‘Tsunami Ready' villages in Odisha

    Two decades after a massive cyclone killed close to 10,000 people in India's Odisha state, the government's efforts to protect coastal villages vulnerable to cyclones and tsunamis has produced a host of safety measures, from reinforced shelters and early-warning systems to search and evacuation training. Two villages were singled out as the first in the Indian Ocean region to achieve UNESCO's "tsunami ready" certification. A drill in 2019 showed how quickly villagers were trained to respond to an imminent threat.

  • A secret hidden in centuries-old mud reveals a new way to save polluted rivers

    Scientists have transformed a stream in Pennsylvania into a marshy waterway because of a restoration project that removed 22,000 tons of legacy sediment built up by colonial-era farming and logging. After removing meters of mud from the banks of Big Spring Run, native vegetation returned, which resulted in the storage of organic carbon tripling in the restored area and the amount of key pollutants in the stream sharply dropping. Similar restoration projects are being tried in other mid-Atlantic states.

  • Could carbon-removal tech make travel more sustainable?

    Climeworks, a Swiss start-up, is using technology to suck carbon out of the air and turning it into stone, essentially cutting greenhouse gas emissions from the atmosphere permanently. Their plant in Iceland is able to turn 50 tonnes of carbon to stone per year. While that amount of carbon won’t solve the climate crisis, they are expanding their work to other countries and are launching a personal carbon removal subscription service as a way for the travel industry to help offset the carbon that they emit each year.

  • Bridging the gender gap through groundwater monitoring in a Rajasthan village

    A group of farmers in India have been trained to monitor their village’s groundwater levels to help its residents make more informed decisions about irrigation based on water availability. The farmers-turned-researchers are known as “Bhujal Jaankars” and they monitor rainfall, dam water levels, and water quality to notify residents so they can plant crops that don’t require a lot of water. While there is a lack of gender diversity in the group, they are working on developing training to include more functional literacy skills to encourage participation from others.

  • Dartmouth Aims To Keep Students Engaged In Hands-On Science With 'Virtual Classroom'

    Geology professors at Dartmouth College in New Hampshire have found ways to overcome the challenges of remote learning and delivered their students a new, and all-around more accessible, virtual class experience. The two professors leading the course recorded 3D video tours and took high-definition photos for students to virtually tour the city of Hanover, and they mailed students rock kits to supplement the learning material.

  • Teachable Moments on the Dock

    A British Columbia project that includes education with regulations is a winning formula for rockfish conservation. Six cameras were placed strategically around the shoreline next to Galiano Island RCAs, and 46 information signs were posted at marinas and docks. The signs provide photos to help identify rockfish, show the boundaries of the RCAs, and offer specifics on the fishing rules. Team members also appear at community events to distribute information on RCAs, explaining how they work and what they are intended to achieve.

  • A new kind of chemistry: Why science is rethinking the humble bed net

    Mosquito nets in Rwanda and other regions are getting undergoing a change due to mosquitos increasingly showing resistance to the usual chemicals sprayed on them. The new nets, currently being piloted throuhgout other regions, are so far showing a higher tolerance to being washed and are routinely repelling more mosquitos than the previous model which only used one chemical, whereas these use a combination.
