8:00 PM | BeerSci: A Decade-Old Beer Is Gross, Right?

Beersci Logo Todd DetwilerNot necessarily! The chemistry behind aging ales, wet-cardboard taste, and what you can do about it. BeerSci Note: From the outset, I decided that I'd occasionally run stories by guest writers in BeerSci. After all, I'm not the only nerd on the planet who likes beer. This week's column was pitched to a fellow PopSci editor, who passed it to me. -- Martha Beer producers make a big deal about drinking beer fresh. Stone Brewery produces an IPA with a drink-by date.

Whence the Earliest Berliners? (Part 1)

This week, I'm hanging out in Chapel Hill at the Isotope Geochemistry Lab on UNC's campus. I'm here to process human dental enamel from Medieval Germans for strontium, to test the hypothesis that the earliest residents of modern Berlin migrated east from Cologne. A bit of background for this project: In the early 13th century AD, two towns were built on opposite sides of the Spree River. Called Berlin (or, sometimes, Altberlin) and Cölln, they eventually became one city in the […]

Automotive Fuel Cells to be Used In Space

Automotive fuel cells are not only good for powering eco-friendly buses and potentially fuel cell cars, they also can be used in space exploration, according to an article co-authored by the JRC and the European Space Agency (ESA) in the scientific journal Acta Astronautica. The article analyzes the present-day hydrogen activities in the terrestrial and aerospace industries, highlighting possible performance improvements and cost savings. Read more »

Compost Program Could Bring Dangerous Fungus into NYC Homes

If Mayor Bloomberg's wildest decay-related fantasies are realized, New Yorkers will soon be sparing their food scraps from the garbage. A new composting program would encourage (or possibly require) people in the city to collect their food waste in a separate container. Yet Bloomberg may want to consider whether a Manhattan apartment has the square footage to fit both its residents and their potentially harmful compost fungi. The New York City recycling plan, as described in the New York […]

Simple fist-squeezing procedure helps athletes avoid choking under pressure

The next time you're faced with a high-pressure situation in sport, try squeezing your left fist tight for thirty seconds. According to a team of German sports psychologists, doing so will activate your right hemisphere, aiding automatic, skilled performance. This helps prevent choking under pressure, they say, which is linked with left-hemisphere activity, excess self-focus and conscious deliberation. Jurgen Beckmann and his colleagues tested their intervention across three studies. In the […]
