Almost all mammals communicate using sound, but few species produce complex songs. Two baleen whales sing complex songs that change annually, though only the humpback whale has received much research attention. This study focuses on the other baleen whale singer, the bowhead whale. Members of the Spitsbergen bowhead whale population produced 184 different song types over a 3-year period, based on duty-cycled recordings from a site in Fram Strait in the northeast Atlantic. Nor is it known if individual bowhead whales maintain the same song throughout their lifetime or if they switch within and/or between years. more »

Some examples: (1)We play pi shuffleboard. I draw 3 big circles on the floor, inside of each other and the kids use rolls of masking tape as pucks. They toss and/or slide circles of tape [identifying marks on side] to see who gets closest to center. Players each have 3 circles of tape that they slide to remove others from center. The winner then challenges the next 3 players until we declare Pi shuffleboard winner.(2)For our Pi Day, my school asked all the faculty members if they would be interested in being “pi’d” and their name was put on a plastic jug. Students would place money in their jug throughout the week and the teacher/faculty member with the most money got pi’d at an all school assembly. We raised a total of about $400! We donated all the proceeds to multiple charities. more »

Restoring some semblance of the sensation of touch has been a driving force behind Stanford chemical engineer Zhenan Bao's decades-long quest to create stretchable, electronically-sensitive synthetic materials. Such a breakthrough could one day serve as skin-like coverings for prosthetics. But in the near term, this same technology could become the foundation for the evolution of new genre of flexible electronics that are in stark contrast with rigid smartphones that many of us carry, gingerly, in our back pockets. more »

Amanda Bayer: "The percentage female at the undergraduate level in economics is well below the percentage female in other social sciences, in business, in humanities and even below the percentage female in STEM fields. Economics is an outlier...There's a huge misconception that it's the math component of economics that's keeping women away. And that's actually not the situation. About 45 percent of math majors at the undergraduate level are women. So, women major in math at a higher rate than they do in economics. Other studies with regression evidence show that math isn't the factor that explains the gap."   more »
