Cheer on the competitors in this zany science cook-off, where teachers compete before a live webcast audience for the sought-after title, "Iron Science Teacher." Parodying the cult Japanese TV program, "Iron Chef," the Exploratorium's Iron Science Teacher competition showcases science teachers as they devise classroom activities using a particular ingredient—an everyday item such as a plastic bag, a milk carton, or a nail.

Bay Area composer and improviser Eric Glick Rieman collaborates with snails, cats, and musicians to embrace a variety of perspectives in his wide-ranging pieces. Glick Rieman is known for his improvisations on the prepared and extended Rhodes electric piano, which he plays with coral, wire brush, bow, and marbles while muting its interior with rubber washers, cloth, and paper.

Theo Jansen’s strandbeests are made up of many interesting organs. They have legs that take elegant strides. They have stomachs to store energy, allowing them to walk even when there’s no wind. They can even detect water and count their steps. Explore strandbeest anatomy and what it reveals about living creatures and the process of natural selection.

How did Jansen first envision creatures capable of walking on sand? Of surviving waves and storms? Explore the iterative and creative processes behind strandbeest evolution during an intimate conversation with renowned artist Theo Jansen and Marina McDougall, director of the Exploratorium’s Center for Art & Inquiry. Learn how Jansen’s singular vision—and the haphazard lessons of sheer trial and error—has shaped his new forms of life, as well as their emerging independence.

Thrown from supernovae, silicon is the eighth most abundant element in the universe and second only to oxygen in the Earth’s crust, which is primarily comprised of silicate compounds, including silica (SiO2), or quartz, commonly found in sand. Silica is absorbed by plants and transformed into intricate glass shells by radiolarians and other microscopic marine creatures. Humans, for their part, have worked silica into glass, ceramics, and devices such as phonograph pickups and crystal oscillators for clocks.

Experience Strandbeest: The Dream Machines of Theo Jansen at the Exploratorium from May 27 to September 5, 2016. Jansen’s strandbeests—“beach animals” in Dutch—are enormous, self-propelling kinetic creations. Constructed largely of PVC tubing and other hardware store materials, strandbeests are mesmerizing in their motions and eerily lifelike. Equipped with sensory organs and ever-evolving survival strategies, they walk a wandering, wind-blown line between art and engineering, mechanics and biology. Physicist-turned-artist Jansen has been creating strandbeests since 1990. Iteratively designed and intricately assembled, Jansen’s self-propelled creatures have evolved over the years, becoming increasingly complex and lifelike, with specialized adaptations to help them survive in their seaside environment. On tour for the first time in North America, the exhibition is illuminated by artist sketches, immersive video, live demonstrations, and the lyrical photography of Lena Herzog, who spent more than seven years documenting the strandbeests’ evolution.

What if your brain showed signs of Alzheimer’s disease—decades before any symptoms occurred? Would you want to know? Alzheimer’s disease, which “can’t be slowed, stopped, or prevented,” is the sixth leading cause of death in the United States, according to the Alzheimer’s Association. Among older Americans, Alzheimer’s is more feared than any other disease, including cancer, stroke, heart disease, and diabetes. Research suggests that the molecular changes of Alzheimer’s disease and other dementias may occur up to two decades before symptoms appear. Clinicians are able to clarify diagnoses of Alzheimer’s disease using molecular “biomarkers” found through techniques such as lumbar punctures or molecular brain scans. Someday, these techniques could be applied to cognitively normal people to predict whether or not they’ll develop the disease. But should they? Professional societies have cautioned against this use, given the lack of proven treatments to prevent Alzheimer’s disease in cognitively normal individuals who test positive. Many of us would value knowing this health information, either in its own right or to help us plan for our futures. But society hasn’t caught up to living with a brain at risk. There are laws prohibiting employment insurance discrimination based on our genetic information; however these laws don’t apply to molecular biomarkers. Those who seek predictive testing may also face serious, unintended consequences from receiving this information.
