Getting there and getting around Scotland's Southwestern Islands

Ferry service to Arran and Islay is the primary way to access the islands from the Scottish mainland. Caledonian MacBrayne (“CalMac”) offers a “hopscotch” ticket package that goes from Ardrossan (close to Glasgow) to Brodick (Arran), across the Kintyre Peninsula, to Port Ellen (Islay), and then back to Kintyre, all on your own schedule, for £150, including ferrying your rental car. (We brought a rental car with us from the mainland, in the interest of being able to access outcrops where and when we wanted, but each island offers a municipal bus service as well.) Reserve a space for your car on the ferry during peak tourist times. Also, be prepared to be stuck on an island for a bit (usually not more than a few hours) if the weather turns.

Pharmaceuticals in urban sediments reveal wastewater treatment effectiveness

People take pills to relieve headaches or syrups to ease a hacking cough, and eventually these medications can make their way into streams and rivers around the world as humans excrete the chemicals. Scientists are now using concentrations of common pharmaceutical products (PPs) in river sediments in Orléans, France, to determine how effective four water treatment plants have been at removing chemicals from the environment.

Down to Earth With: Deep-sea biologist Stace Beaulieu

People often find their way to the geosciences after a college class sparks their interest. But not Stace Beaulieu, a senior research specialist at Woods Hole Oceanographic Institution (WHOI) in Woods Hole, Mass. — she knew what she wanted to do at age 6. Beaulieu grew up in Florida and spent her childhood snorkeling and reading science magazines with pictures of deep-sea creatures that tantalized her imagination and piqued her curiosity. “I had a one-track mind pretty much from elementary school through grad school — I never changed my mind. I was so excited about learning about what was deeper. I still am today.”

When agriculture went to our heads

The dawn of agriculture left an indelible mark on early human societies, and a new study finds that eating softer, cultivated foods subtly changed the shape of human skulls. Scientists have long suspected that the transition from hunting and foraging to farming and raising livestock would have affected our skulls, specifically the mandible and other anatomy involved in chewing, but quantifying such changes has proven difficult.

Northern Finns didn't starve during Little Ice Age

Today, Finland’s Northern Ostrobothnia region is one of the northernmost places in Europe that can support agriculture. But how this region fared during the Little Ice Age — a period of globally cooler temperatures that lasted roughly from A.D. 1300 to 1850 — is unknown. Scientists assume the climatic cooling would have adversely affected food supplies. Now, however, the discovery of a mysterious medieval cemetery in northern Finland dating to the middle of the Little Ice Age is offering clues that the inhabitants were well fed and well suited to the northern clime.

Troubled waters: Lead lurking in U.S. water supplies

In 2014, Flint, Mich., started drawing its drinking water from the highly corrosive Flint River, which leached lead from old pipes, exposing the population to lead poisoning. Such aging infrastructure exists in towns across the nation, leaving many to wonder if what happened in Flint could happen to them. The answer in many cases is yes.

T-A-P (Testing, Awareness, Prevention)

Not all water corrosivity issues are obvious. For this reason, Ryan Gordon, a hydrogeologist at the Maine Geological Survey, recommends that regular tests be conducted at least once every three years.

How long will the lava flow? Predicting eruption durations with satellite monitoring

If you live near a lava-spewing volcano, it could be helpful to know just how long molten rock might flow during a fiery eruption. In a new study, scientists report that they can calculate how long lava-flowing eruptions might last based on satellite data.
