Sigma Xi members are invited to explore the world with Betchart Expeditions in 2016 to see a Total Solar Eclipse in Indonesia, and Annular Solar Eclipses in Madagascar and Tanzania. In 2017, there will be voyages in Chile and to Antarctica which will include annular eclipse viewing in Patagonian Chile and Argentina. The trips are offered in conjunction with The Planetary Society and will include excellent leadership. Highlights will include lemurs in Madagascar, Borobudur World Heritage site in Indonesia, and the San Rafael Glacier World Heritage site in Chile.

Occasionally science outreach works and expands the audience of people attentive to science. One such occasion was on the evening of Dec. 9, 2015, in Louisville, Kentucky. The Louisville Chapter of Sigma Xi sponsored a program at the Louisville Free Public Library that drew 600 people. They came to hear two scientists from two different centuries speak. The event was titled: “Beneath the Same Sky: A Vatican Astronomer and a Civil War General Speak to Louisville about the Heavens.”

Please join us for the latest in our series of hangouts with Sigma Xi's Distinguished Lecturers. We will be joined by archaeologist and anthropologist Todd Surovell, freshly back from fieldwork in Mongolia. Dr. Surovell tries to determine the factors that structure the archaeological record, from human decision making to site formation.

Help spread the word about Sigma Xi’s science communication competition by posting the event’s flyer at your local institutions. In this online contest, students compete in graduate, undergraduate, and high school divisions by submitting a website with a personal video, research abstract, and technical slideshow. All participants receive feedback from the judges. Top presenters in each division earn a prize up to $500. Presenters could also win the $250 People’s Choice Award. The deadline to register and submit a presentation website is March 21.

The future of search-and-rescue missions may be in the form of insect-sized robots. Researchers are creating such robots because of insects’ unmatched ability to navigate through a wide variety of environments, including the rubble of collapsed buildings. Alpert Bozkurt of North Carolina State University has found a way to control insects directly.

Tiny cracks can actually be a big deal when they're forming inside parts of your car or, say, a metal shell that's flying into space. University of Illinois research, led by Professors Nancy Sottos and Scott White, has led to a polymer coating that could be an important early warning system, making it easier to find trouble spots before something really bad happens. When cracks form in the polymer, micro-beads also crack open, causing a chemical reaction that visibly highlights the damage with color.

Evolutionary theory predicts that pairs of chromosomes within asexual organisms will evolve independently of each other and become increasingly different over time in a phenomenon called the 'Meselson effect'.
While this event was first predicted almost twenty years ago, evidence for it has proved elusive.
Now, researchers from the University of Glasgow have demonstrated the Meselson effect for the first time in any organism at a genome-wide level, studying a parasite called Trypanosoma brucei gambiense (T.b. gambiense).

Do kiwis and sauerkraut make your mouth water? If so, you can thank the mood-regulating neurotransmitter called serotonin, which may also enable you to taste sour foods, according to a study published in the Journal of Neuroscience and covered by Science News.

The idea of getting free energy from activities we do every day, like walking, has proven to be a pipe dream — not that companies haven't tried. However, MIT scientists have tapped a new way to generate energy from bending that could actually make it feasible. Rather than using mechanical piezoelectric devices, the team developed new materials based on electrochemical, battery-like technology. When bent back and forth, they generated alternating current power with a surprising amount of efficiency, meaning you could one day tap your own kinetic energy to power devices.

Miniature self-assembling “flasks” created at the Weizmann Institute of Science may prove to be a useful tool in research and industry. The nanoflasks, which have a span of several nanometers, or millionths of a millimeter, can accelerate chemical reactions for research. In the future, they might facilitate the manufacture of various industrial materials and perhaps even serve as vehicles for drug delivery.
