I predicted that any insect that flies at night must have a way of dealing with their fiercest nocturnal predators—bats. More recent findings by Akito Kawahara of the University of Florida and my former graduate student Jesse Barber of Boise State University confirm this prediction in two exciting ways.

June 3 marks the 50th anniversary of the first American space walk, or Extravehicular Activity (EVA) in NASA terms. The technology and design of space suits—called Extravehicular Mobility Units in NASA parlance—has also evolved greatly over the past 50 years. In the September-October 2015 issue of American Scientist, we will feature an article from Dave Cadogan, Director of Engineering at ILC Dover, the only company that currently makes US space suits.

Besides being Richard Feynman’s birthday, May 11 marks National Twilight Zone Day. The establisher of the holiday, as well as the reason this date was chosen, is appropriately murky (it’s not the date the show first aired). We like to think that Feynman might have been amused by the association.

May 11 marks what would have been the 97th birthday of Richard Feynman, the legendary physicist who helped to found the field of quantum electrodynamics. Feynman’s name has often graced the pages of American Scientist. Here we collect a dozen links as a jumping-off point for those looking to know more about this fascinating scientist.

We recently published an article about the results of a 4.5-year program of research on gender’s influence on faculty hiring preferences for tenure-track STEM assistant professorships. Our methods brought up an interesting issue about the types of adjectives used to describe job applicants, one that we did not have space to address in the paper.

A student in one of my daughter's high school math class stood up in disgust and exclaimed "Why do we have to learn math for 12 years when we are never going to use any of it?" You might think that as a mathematics educator I would find this statement upsetting. Instead, the student’s question got me thinking about the fact that she saw no connection between the mathematics and her future. How might mathematical modeling improve the experience of mathematics for students such as the one in my daughter’s class?

To celebrate Independent Bookstore Day we couldn’t resist recommending some reads worth seeking out (or ordering from) your favorite independent bookstore. And as usual, our celebration here at Science Culture comes with a twist: We’re going all-indie today, focusing specifically on science, math, and tech books issued by independent publishers—truly the unsung (and occasionally unpaid) heroes of the book-producing world. Culled from a long and worthy list, here are six recommendations for the day.

It’s doubtful we would have Earth Day without Rachel Carson. Her pioneering 1962 book Silent Spring sparked the environmental movement and infused ecological ideas into mainstream thinking. So to recognize this date, I combed through the archives of American Scientist to get a sense of how scientists have discussed Carson and Silent Spring over time.

We’ve all heard warnings about the damage that too little sleep can inflict on immune resistance, blood pressure, and insulin sensitivity—to say nothing of mood. But what harm could possibly come from too much?

For millennia, fundamental units of time were referenced this way. The ever-changing Earth rotation interval was divided into 86,400 seconds. But Earth rotation is not constant and is unpredictable. This meant that the duration of a second had to be changed occasionally to maintain essential synchronization with Earth rotation.

A headline is designed to convey the gist of a story, and also entice a reader to want more information. But sometimes the headlines themselves can inspire the imagination. Resident cartoonist and Contributing Art Director, Tom Dunne, created some off-the-cuff doodles, based solely on the headlines from Sigma Xi's SmartBrief.
