What is Sigma Xi?
Sigma Xi is the premiere international honor society of scientific research. One of the first and most widely recognized scientific societies; its mission is to foster a creative and symbiotic relationship between science, technology and society. In addition, Sigma Xi encourages appreciation and support of original investigation in science and technology, by participating in programs and activities whose primary focus is research for the purpose of education.

Sigma Xi, with a membership in excess of 60,000 scientists and engineers, has more than 500 chapters throughout the world. Chapters can be found within colleges and universities, government laboratories as well as industry research centers. Since its creation in 1886 on the campus of Cornell University, more than 180 Sigma Xi members have received the Nobel Prize in the areas of science, economics and the prestigious peace award.

Mayo Foundation Chapter
Sigma Xi maintains its strength by working at the grass roots level. The Mayo Foundation Chapter of Sigma Xi was chartered in 1919 and currently has an active membership of about 250 people. These individuals have varied scientific backgrounds including, but not limited to: physicians, clinicians, clinician-scientists and researchers.

By coordinating public lectures by renowned scientists, awarding prizes and grants to individuals who show exceptional science merit, and participating in the regional science fair, the Mayo Foundation Chapter of Sigma Xi works to educate and inspire the local and regional community to appreciate scientific research, both pure and applied.

Public Lectures
The Mayo Foundation Chapter of Sigma Xi coordinates lectures by some of the world's foremost authorities in science and technology. This gives the community a chance to learn about the latest scientific advancements.

Lecture subjects can range from anthropology to zoology, mathematics to chemistry or medicine to space exploration. Some recent topics have included: The Cow that Stole Christmas (BSE in America); Global Climate Change: A view from the ice; Using a multilevel approach to study sexually selected traits; Earthquake research; Limits of Human Endurance: Lessons from the Human Genome Project, and History of Native Americans in Minnesota. Lectures are free of charge and open to the public. Times and dates can be found by selecting the "Events" link on this page in the upper left side.

Prizes and Awards
Annually, the Mayo Foundation Chapter honors a local science teacher for his or her outstanding work in the field of science education. Teachers are nominated by peers within their own science department and are chosen based on their ability to generate an excitement for science in the minds of their students. Public schools and local colleges are invited to participate.

In 1997, the Mayo Foundation Chapter of Sigma Xi initiated a grant-in-aid program to encourage students in middle school and high school to participate in science programs at their school. The program began providing initial funds or "seed money" for such things as travel awards for students to attend national science competitions.

Since that time, grants have been awarded for other science related projects such as the beehive exhibit for the Quarry Hill Research Program, Aquarium for marine biology, and development of a radio telescope at Mayo High School.

Applications for the grants are taken on an ongoing basis and are competitive. For information regarding the application process, phone the Mayo Foundation Chapter secretary at 507-284-2161 or see the Sigma Xi web site at

GATEway Science Fair
The GATEway Science Fair was started in 1990 by GATEway, the Rochester Chapter of the Minnesota Council for the Gifted and Talented (MCGT).  This science fair is open to ALL grade 3-6 students in Rochester and the surrounding area, gifted or not.  Sigma Xi has been hosting the GATEway Science Fair in the Landow Atrium of the Mayo Clinic Gonda building since 2008, as well as members volunteer as project reviewers for the event.  The mission of the fair is to foster enthusiasm for science in a non-competitve setting and to promote a positive learning experience for students in scientific literacy, presentation skills and critical thinking.  Besides presenting their projects to adult science professionals, students also attend an education program presented by the Science Museum of Minnesota.  Participants receive written reviews, a certificate of participation and a fair t-shirt. GATEway continues to be deeply grateful for the ability to use Mayo facilities for the science fair.  The space has allowed the fair to grow to regularly receiving between 200 and 275 registered partipants each year.  The participants and their families are always pleased with the convenience and beauty of their surroundings, and it adds to the students' excitement to be able to come to Mayo to present their projects.

Regional Science Fair
Every year students from Rochester and surrounding communities participate in a regional science fair. The winners at the regional level then go on to compete against other regional science fair winners in a statewide competition.

The members of the Mayo Foundation Chapter of Sigma Xi participate in the regional science fair on several levels. Using their experiences in the fields of science and technology, Sigma Xi members volunteer their services to be judges of the competition.

The chapter provides several sources of funding for the science fair. There is an unrestricted educational grant that is provided to the science fair coordinators to assist with the costs of staging the event. These awards are given to those students who need assistance deferring their individual costs. Finally, there are awards, funded by the Mayo Foundation Chapter of Sigma Xi, which are bestowed upon those students who have shown excellence in the writing of their accompanying research papers. Awards are selected on the basis of originality, composition/presentation and their development of a central theme or hypothesis.
