Catching a Diversity of Fish Species — Instead of Specializing — Means More Stable Income for Fishers

A team of scientists analyzed nearly 30 years of revenue and permitting records for individuals fishing in Alaskan waters and tracked how their fishing choices, in terms of permits purchased and species caught, influenced their year-to-year income volatility.

Genetically Altered Mice Bear Some Hallmarks of Human Bipolar Behavior

Johns Hopkins researchers report they have genetically engineered mice that display many of the behavioral hallmarks of human bipolar disorder, and that the abnormal behaviors the rodents show can be reversed using well-established drug treatments for bipolar disorder, such as lithium.

“Superbug” Bacteria Gang Up on US, Fueled by Antibiotic Use, Nursing Home Study Suggests

What’s worse than getting exposed to a kind of bacteria that modern antibiotics can’t kill? Getting exposed to more than one – because they may work together to cause an infection, new research suggests. It’s time to think about such bacteria as members of an antibiotic-resistant ecosystem in healthcare environments – not as single species.

Mystery Solved: How Thyroid Hormone Prods Red Blood Cell Production

For more than a century, the link between thyroid hormone and red blood cell production has remained elusive. Now, Whitehead scientists have teased about the mechanism that connects them, which could help scientists identify new therapies for specific types of anemia.

Coral Skeletons May Resist the Effects of Acidifying Oceans

Coral skeletons are the building blocks of diverse coral reef ecosystems, which has led to increasing concern over how these key species will cope with warming and acidifying oceans that threaten their stability. New research provides evidence that at least one species of coral build their hard, calcium carbonate skeletons faster, and in bigger pieces, than previously thought.

Research: City’s Infrastructure, Not Population, Plays Greater Role in Ecological Impact

The ecological footprint of a city spreads far beyond its city limits, resulting in local and total extinction of hundreds of aquatic species in North America. Recent research quantifies the adverse effects while looking ahead to how cities can help.
