  • Could crushed rocks absorb enough carbon to curb global warming?

    Scientists are testing if adding alkaline substances to seawater can allow oceans to absorb more carbon dioxide emissions. Early tests suggest this could be a potential way to combat climate change, but there are still many questions about how this can scale, how it impacts the natural ecosystem, and if it’s cost effective to implement.

  • They Said the Tornado Would Hit at 9:30. It Hit at 9:30.

    Advances in meteorological technology have helped drive down the fatality rate from tornadoes in the U.S. to a fraction of what it was a century ago. Violent tornadoes rarely evade advance detection, thanks to weather satellites, advances in radar, and a communication system to announce warnings. The deadly tornadoes that struck Kentucky and other states in December 2021 illustrate the ways in which even this system – one scientist called it "one of the most incredible success stories in applied science" – can fail, including when people ignore warnings or buildings cannot withstand the high winds.

  • A River's Right to Flow

    In order to preserve and protect rivers a new movement that grants rivers personhood rights is growing. In places like New Zealand and Oregon, where some of these measures have passed rivers have the right to flow without having to be used as a resource for consumption. In New Mexico, the state engineer approved a water lease submitted by the National Audobon Society. The lease allows about 13 million gallons of water to flow annually solely for its own sake, similiar to personhood rights. The creative approach is one way conservationists are fighting for water preservation.

  • Haiti's citizen seismologists helped track its devastating quake in real time

    Volunteer citizen seismologists in Haiti are collecting data on earthquakes and aftershocks with equipment provided by researchers to better understand seismic hazards and fault locations in the country.

  • The force that could redraw the peninsula of India

    In the South Indian coast, erosion is leading to disappearing beaches. A study found that this erosion was in part due to man-made structures like a harbor that was built in the late 80s, groynes, and seawalls. These structures were interfering with the natural movement of sand. To fix it, they needed a structure that could block waves but also allow sand movement, the solution? An artificial reef. It was installed and some beaches are already seeing the results.

  • Indian Cities Prepare for Floods with Predictive Technology

    In coastal cities in India, floods have led to hundreds of deaths and millions of people being displaced. To address the issue, scientists had to address a variety of factors: hydrology of the upstream region; river, tidal, and storm surge modeling; and a high-resolution digital elevation map of the city. A group of scientists from 13 research institutes and government organizations looked at all those factors and came up with a real-time flood forecasting system. It generated 800 flood scenarios. When it rains the model predicts the most vulnerable sites.

  • Drug testing takes off in the Laurentians — even dealers are doing it

    To reduce overdose deaths from the increasing number of deadly substances found in street drugs, Centre SIDA Amitié uses lab testing to help understand exactly what drugs users are putting in their bodies and how to slow the spread of deadly drugs. They distribute testing kits to hundreds of people every year, analyze urine samples, have handed out 12,189 naloxone doses, and trained over 1,000 people to administer the drug. Staff works directly with clients in communities that don’t have access to many resources, also helping them navigate court proceedings, find housing, and get into rehab if interested.

  • The Bright Side of the Green Crab

    The invasive European green crab was wreaking havoc on the soft-shell clam fishery in Nova Scotia. But fishers, researchers, and park officials worked together to remove as many of them as possible and find an alternative use for them. Their efforts were working: eelgrass meadows and clam populations were rebounding. Now, they’re testing how these crabs can be used in lobster bait, bioplastics, or even fertilizer for gardens.

  • The world's first 'infinite' plastic

    There are several chemical recycling methods being tested throughout the world, including one of the latest ones in the United Kingdom. Mura Technology is building the world’s first commercial-scale plant that can recycle all kinds of plastic and turn them into oil. Their method aims to process 80,000 tonnes of plastic waste every year once the plant opens in 2022. While some criticize that the chemical recycling process is very energy intensive and is not always profitable, the new Mura plant already has partnerships lined up with some plastic manufacturers.

  • Indonesia coral reef partially restored in extensive project

    A coral reef in Indonesia has been partially restored due to the collective efforts of conversation groups, nonprofits, and even a pet food company. They laid structures on the seabed to help stimulate reef growth. Because of their efforts, they have been able to increase coral cover from 5 percent to 55 percent.
