It seemed like a good job at first. Starting in 1917, the United States Radium Corporation hired teenage girls and young women to work as painters. Using fine paintbrushes, the workers applied glow-in-the-dark paint onto watches and military instruments. The paint shone brightly because it contained radium, a substance that management assured the young workers was harmless.In the book The Radium Girls: The Dark Story of America’s Shining Women, author Kate Moore detailed how the workers were t ...read more

Earlier this month, we visited the Cascade Range volcanoes on British Columbia. Today we're hitting the volcanoes in Washington, including likely the most famous volcano (after Yellowstone) in the United States as well as a contender for the most powerful (known) eruption in the Cascades. All the images come from the Sentinel-2 Earth observing missions launched by the European Space Agency. This missions will become even more vital for monitoring the planet after NASA's Terra and Aqua satellite ...read more

Many of our local green spaces like yards, parks, and porches are home to mostly introduced, non-native plants that do little to maintain a healthy regional biodiversity.Want to restore native biodiversity? It’s possible, and the solutions are within reach: try rewilding your community with native plants. Mary Reynolds created ...read more

Animals sporting elongated curved canine teeth have appeared twice in the fossil record, millions of years apart. One lineage, the nimravids, went extinct about in North America about 23 million years ago. Then the saber-toothed tiger vanished about 8,000 years to 10,000 years ago. More recently, saber teeth have also evolved in “true” cats of the Felidae family.Scientists have long wondered why saber teeth emerged over different times and places, vanished, then re-appeared. A new study in C ...read more

Sometimes one clue at a crime scene can provide the key to unlocking an entire mystery. Such is the case with a single gold earring found inside a building that burned to the ground about 2,200 years ago in Catalonia, according to a report in Frontiers in Environmental Archaeology.The fact that the earring was hidden — both in a pot and in a nook inside a wall — suggests that its owners knew Hannibal’s Carthaginian army was heading their way. Because the earring was in one of the several b ...read more

Many people understand the concept of bias at some intuitive level. In society, and in artificial intelligence systems, racial and gender biases are well documented.If society could somehow remove bias, would all problems go away? The late Nobel laureate Daniel Kahneman, who was a key figure in the field of behavioral economics, argued in his last book that bias is just one side of the coin. Errors in judgments can be attributed to two sources: bias and noise.Bias and noise both play important r ...read more
