The first-ever meeting of world leaders to address the crisis facing oceans took place in France, last week. The One Ocean Summit discussed illegal fishing, plastic pollution, and carbon emissions from the shipping industry.

About one in three people in the U.S. have been found to have detectable levels of a toxic herbicide in their bodies that has been linked to birth defects, reproductive problems, and leukemia in children, among other health issues. A new study from George Washington University shows that the chemical called 2,4-D has seen a resurgence among farmers since weeds have become resistant to glyphosate—the compound commonly used in Roundup®. The National Pesticide Information Center says there are more than one thousand products with 2,4-D that are sold in the United States, including Weed B-Gone™ made by Ortho®.
Last year, a study by the University of California showed that, if the state covered all its 4,000 miles of canals with solar panels, it could save water while making electricity. According to the study, evaporation would be cut by as much as 82 percent, saving about 63 billion gallons of water annually—about the same amount required to irrigate 50,000 acres of farmland or meet the residential needs of more than two million people. The researchers also showed covering the canals with solar installations could generate about one-sixth of the state’s current installed capacity, about half the projected new capacity needed to meet California’s goal of cutting greenhouse gas emissions by 40 percent by 2030.

Dinosaurs were just like us. They got sick and were miserable. That was probably the case with “Dolly,” a long-necked sauropod, who lived in present-day Montana, which 150 million years ago in the Late Jurassic epoch, was a warm, humid coastal river system. Cary Woodruff, a paleontologist at the Great Plains Dinosaur Museum in Malta, Montana, was recently examining Dolly’s fossils, which were unearthed in the state more than 30 years ago, when he noticed some unusual broccoli-like protrusions in several of her neck bones.
Hypothetical life restoration of Dolly. Note that the pulmonary disease infecting this animal would not been externally evident, but the probable pneumonia-like outward symptoms would have included coughing, labored breathing, nasal discharge, fever, and weight loss among others. | Artwork by and copyright of Corbin Rainbolt. / Woodruff et al., doi: 10.1038/s41598-022-05761-3.
