  • Electric car batteries with five-minute charging times produced

    Batteries that can be fully charged in five minutes have been created for the first time, allowing electric cars to recharge faster. The Israeli company StoreDot produced 1,000 of these new lithium-ion batteries, which can be recharged for 1,000 cycles while retaining 80 percent of the original capacity. It could be a few years before they are mass produced, but the CEO of the company says that this feat “demonstrates it is feasible and it’s commercially ready.”

  • Simple change to fishing gear saves thousands of birds in Namibia

    Tens of thousands of vulnerable bird species have been saved over the last decade thanks to new equipment that has been installed by Namibian fishing boats. By fitting colorful hosepipe to lines towed behind boats, a study has shown that birds are scared away and don’t end up getting tangled in the lines. The material is also fairly cheap to implement, which allowed the solution to be widely implemented.

  • How Solar Panels Could Help Save Struggling Farms

    As the amount of farmland decreases in the United States and climate change brings hotter and drier conditions, many farmers are turning to agrivoltaics — growing crops and installing solar panels on the same land — as a way to make ends meet. Research on a garden in Arizona showed that certain crops like tomatoes and chiltepin peppers were able to thrive under the shade of solar panels, while also improving the solar panels’ productivity. “It’s a very unique positive feedback,” said one of the researchers.

  • A Thin Green Line With Global Impact

    For over a decade, environmentalists, Indigenous tribes, ranchers, politicians, scientists, and fishers in the Pacific Northwest have been able to defeat more than 20 proposals from coal and oil firms to ship fossil fuels from their ports. Through protests, public hearings, and petitions to government agencies, activists blacked almost every fossil fuel effort in the region between 2004 and 2017.

  • One, two, tree: how AI helped find millions of trees in the Sahara

    Tree mapping helps researchers understand deforestation and climate change, however the technologies used often miss trees that aren’t clustered. Researchers, in collaboration with NASA, used high-resolution satellite images, previously only available to commercial entities, to find a surprisingly large number of trees in the Sahara Desert. Using AI deep learning and one of the world’s most powerful supercomputers at the University of Illinois, they identified more than 1.8 billion trees, manually marking nearly 90,000 so the computer could “learn” which shapes and shadows indicated the presence of trees.

  • Cooperation and Chocolate: The Story of One Colombian Community's Quest for Peace

    Plagued by an internal war, a group of villages in Colombia created a “Peace Community,” declaring themselves neutral in the conflict and focusing their efforts on cultivating the 150 hectares of cacao trees in collectively owned plots to sell to global markets. While villagers still experience violence, the earnings from their crops go into a collective pot and the community decides together how to distribute the funds. “To them, this is actually a very profound act of transcending traditional capitalist society models and building something together,” says an anthropologist who has studied the community.

  • How Bison Are Saving America's Lost Prairie

    Tall grass prairie used to span across 13 states in North America. However, after settlers arrived grassland prairies were decimated. By reintroducing bison to the land along with seasonal fires, the nature conservancy, which manages the Joseph H. Williams Tallgrass Prairie Preserve in northeastern Oklahoma, resuscitated the prairie. The preserve is the largest tract of grassland prairie remaining in the world.

  • Network Connects Indigenous Knowledges in the Arctic and U.S. Southwest

    The Indigenous Foods Knowledges Network (IFKN) connects Indigenous scholars, community members, and leaders from tribes in the Arctic and the U.S. Southwest to work together on achieving food sovereignty. By visiting each other’s lands, they share their traditional knowledge on farming practices and river restoration. Because of the network, they received a grant to study the effects of COVID-19 on food access for Indigenous communities. “We can learn from one another, teach each other, and also work together on finding different solutions,” said a member of the IFKN steering committee.

  • Indigenous agroforestry revives profitable palm trees and the Atlantic Forest

    The Jussara Fortress program helped the indigenous Guarani people turn small-scale production of jussara palm hearts, a delicacy, into the main source of income. Sustainable growing techniques protect the jussara, which was endangered by deforestation and over-harvesting. This, in turn, provides for a biodiverse system with environmental and health benefits for the Ribeirão Silveira Indigenous Territory. The program planted more than 100,000 of the trees, which need a decade to yield a small amount of marketable product.

  • Human composting now legal, begins in Washington

    Instead of burying or cremating a body after the person has died, some are turning their loved ones into compost. Washington recently became the first state to approve human remains composting, which environmentalists heralded as a greener alternative because it uses less energy. Herland Forest, a natural burial cemetery, is doing one of the first licensed “natural organic reductions” using a “cradle” with wood chips, bacteria, fungi, and oxygen to help speed up the decomposition process. This can take several weeks, but it could become a popular option.
