In the modern world, it’s easy to take for granted some specialists and structures that keep us healthy or safe on the daily: sanitation workers and pharmacists, bridge beams and highway paint, even fungi and maggots (and soon their secretions?) — to name a few. Most of us could add environmental scientists to that list. Whether or not you have met an environmental scientist in the flesh, it’s a solid bet that their work has shaped your life, often for the better. This can apply to daily p ...read more
The cold freshwater in Lake Huron kept the sunken ship Ironton intact for over a century — including all three of its masts and a lifeboat that took five lives — but also brought the ship’s destruction. The Ironton sank in September 1894 after colliding with a steamer ship named the Ohio. The sunken ship had been missing for around 120 years with only rumors of its location. Recently, researchers from the state of Michigan, the Ocean Exploration Trust and NOAA discovered the ship in what ...read more
It’s obvious to many of us — whether we’re an only child or not — that siblings are often different from each other. Judy Dunn, emeritus professor of developmental psychology at Kings College London, and Robert Plomin, professor of behavioral genetics at the same institution, were among the first scholars to start empirically questioning why this happens. Drawing from differences they noticed in Dunn’s children, over the past 30 years, they’ve tested siblings’ variations in charact ...read more
For many years, the Cave of the Malalmuerzo (“bad lunch”) near Granada, Spain, located near rocky farmland, stood open to the public. Local residents stooped under the low ceiling and wound their way through stalactites, and some made the belly-crawl to the deeper reaches of the cave and the early paintings there. They took home “some artifact […] ceramics, bits of bone, etc.,” writes a local businessman. In 1983, the first archaeologists showed up, but the souvenir-hunting continued ...read more
Technically, every single object in the universe with mass or energy emits a gravitational field, and scientists have been able to measure the gravitational field of objects far smaller than a human. General Relativity Einstein revolutionized our understanding of gravity with his magnum opus, the general theory of relativity. The theory transformed our perspective of gravity from a simple property of objects relating to their mass, to a view of the cosmos where space and time can bend, flex and ...read more
