  • A ‘FitBit for squid' could help track the ocean's squishier species

    Squids play an important role in the ecosystem, so scientists are focusing efforts on better understanding how the species adapts to climate change. By creating a "FitBit for squid," scientists have successfully been able to monitor soft-bodied invertebrates.

  • Beet juice, molasses and mag: Colorado's search for the right highway de-icing mixture

    As Colorado searches for the most effective and efficient de-icer for its winter weather, the state weighs the pros and cons of using agricultural by-products like beet juice and molasses as base ingredients. The quest for finding the perfect de-icer comes up against environmental concerns – especially considering the robust outdoors of Colorado – as well as budget limitations and effectiveness.

  • Inside the daring plan to map every coral reef from space

    Researchers are using satellite imagery and data to create the first global, high-resolution map of all coral reefs. The project, known as the Allen Coral Atlas, will help provide a baseline for scientists to monitor bleaching events and other short-term changes, which could lead to devastating changes.

  • New tsunami warning system

    The warning system in Indonesia to alert residents of tsunamis could not prevent disaster in Sulawesi because it hasn't worked for six years after many of the surface buoys were vandalized. However, a new system is underway where sensors on the bottom of the ocean detect tsunami waves and send acoustic signals back to shore, giving people 20 to 30 minutes warning to evacuate. A prototype has been installed, with more testing and infrastructure development planned.

  • Cool Ways of Keeping Things Cool

    Inventors have come up with energy-efficient refrigeration options. A fridge uses water and ice to protect vaccines in places with irregular access to electricity. An engine that runs on liquid nitrogen reduces fossil fuel dependence in food shipping.

  • How Forecasting Models Are Changing the Way We Fight Fires

    The National Weather Service has been helping firefighting crews better prepare for and fight wildfires. They’ve developed a model called the High-Resolution Rapid Refresh-Smoke (HRRR-Smoke) to show where there’s higher smoke density and what direction it’s heading toward. The agency is hoping to continue their work to become better at preventative measures so that towns and cities can prepare ahead of time.

  • Can the Great Lakes continue to fend off an increasingly thirsty world?

    The Great Lakes contain 84 percent of the surface freshwater in North America—a staggering 21 percent of the surface freshwater worldwide. To manage the resource sustainably, all eight lake-bordering states, Congress, and Canadian provinces created the Great Lakes Compact in 2008, which has regulated and curbed water use. An evaluation of the agreement ten years later shows promising yet mixed results. And critically, it asks whether strong policies can withstand a future of growing water scarcity.

  • Climate Change, the Rio Grande and Border Water

    The Rio Grande River, which provides water to 6 million people and irrigates 2 million acres of farmland, is one of many transnational sources of water imperiled by climate change. Indeed, many states and countries that share water are drawn into conflict over dwindling resources. One relationship between officials in Mexico and the U.S. offers some hope that (with the right coaching) countries can cooperate, even in the face of greater political problems.

  • The clock is ticking on dealing with western Kansas' drying Ogallala Aquifer

    Western Kansas' finite Ogallala aquifer is the bedrock of an agricultural region that accounts for 10 percent of Kansas' economy. But thanks to decades of over-drafting for irrigation, the aquifer is on track to run dry in the not-so-distant future. Now some are calling for regional conservation, and some smaller programs have shown promise; however, the challenges of scalability and political wrangling remain vast.
