Science Pub Portland: Liquids in Space (4 February 2016)

February 1, 2016 by Dave Leave a Comment

OMSI Science PubJoin OMSI and Mark Weislogel, PhD, Professor of Mechanical and Materials Engineering at Portland State University on Thursday, 4 February 2016 for Science Pub Portland: Liquids in Space at the Empirical Theater at OMSI (1945 SE Water Ave.).

There are as many as 50 different drinks available to astronauts aboard the International Space Station. Beer is not one of them. But coffee is. Understandably, the coffee is sucked through straws inserted into sealed bags. But wouldn’t it be more pleasurable to sip from a cup, sensing the warmth and aromatics, and chilling from the pressure of the day with co-workers a little like back on earth? Believe it or not, this isn’t easy to do. The problem is the lack of gravity(!) and its impact on the whole process of drinking.

In this presentation we tell the story of the Space Cups which were designed at IRPI LLC in Wilsonville in collaboration with NASA, demonstrated in the low-gravity drop tower at Portland State University, launched to the Space Station on a Space-X rocket, and enjoyed by the astronauts aboard the International Space Station. We will present fun video of astronaut antics while drinking in the galley of the Space Station, but also the deeper story of microgravity capillary fluidics research that undergirds our work and illuminates a direction for the design of advanced spacecraft for the more demanding exploration missions of the future.

The Portland Science Pub takes place monthly at the Empirical Theater at OMSI. Check in at the theater entrance (doors open at 5 PM) – there’s a $5 suggested admission. OMSI’s restaurant Theory, and the Empirical Cafe are open and you can take food and drinks into the theater with you.

Parking is free for the event, but consider taking the streetcar or any of the multitude of buses that cross the Hawthorne Bridge (eastbound/westbound), which has stops a few blocks from OMSI.


Science Pub Portland: Earthquakes in Oregon

January 17, 2016 by Dave Leave a Comment

OMSI Science PubOMSI presents Science Pub Portland: Earthquakes in Oregon on Tuesday, 19 January 2016 at the Empirical Theater at OMSI (1945 SE Water Ave.).

In the Pacific Northwest of the United States, the Juan de Fuca plate is being subducted under the North American Plate at the Cascadia Subduction Zone. The lecture will discuss the hazards of and the preparedness for ground shaking, liquefaction, landslides and tsunamis along the subduction zone. What are the differences of recurrence intervals for large earthquakes on the northern and southern margins?

Much of the region was not thought to be an earthquake region so earthquake building standards are fairly recent. How does the chance of crustal, plate and subduction quakes affect building codes, emergency preparedness, siting of critical facilities, building of bridges, and transportation corridors in the region? What have we learned from recent subduction quakes around the world that can be applied to the Pacific Northwest? What can the region expect after a large quake?

OMSI Science Pub: Arctic Change (20 October 2015)

October 18, 2015 by Dave Leave a Comment

OMSI Science PubArctic Change is the topic of the latest OMSI Science Pub Portland on 20 October 2015 at the Empirical Theater at OMSI (1945 SE Water Ave.).

Join climate scientist Zach Brown as he describes his research in the High Arctic. Through photos and stories, he will share the experience of climbing aboard an icebreaking vessel for weeks in the 24-hour daylight and frigid temperatures of the polar seas. Zach will also delve into what his team has learned: the way that changes in sea ice are affecting the biological realm of this harsh and remote region of the planet – as well as inviting controversial industrial expansion.

Zach will also share his current work: creating an institute for education and research at a remote and beautiful homestead in his homeland of Alaska. To spread word of this effort, last summer after completing his PhD, he set off on a 4-month, 2,300-mile trek from Stanford University to Southeast Alaska, traveling solo on foot and by kayak.

Zach Brown grew up surrounded by the wilderness of Southeast Alaska. With parents in the National Park Service, Zach had ample opportunity as a boy to explore Glacier Bay and the Tongass National Forest, experiences that gave him a lasting love of the natural world.

OMSI Science Pub: Deep-Sea Hot Springs (5 October 2015)

October 5, 2015 by Dave Leave a Comment

OMSI Science PubOMSI presents Deep-Sea Hot Springs as part of the Science Pub series on 5 October 2015 at the Hollywood Theatre (4122 NE Sandy Blvd).

Most of the biodiversity of life on Earth is microbial. These microscopic organisms occupy almost any conceivable habitat where there is available water, energy and carbon for growth. They live in some of the most salty, cold, hot, nutrient-starved, dry and acidic places on this planet, and they form critical partnerships with many other organisms, including us. At deep-sea vents, microorganisms form the base of the food web, fueling the chemosynthetic-based ecosystem. Here, as the very hot hydrothermal fluids mix with the cold seawater, minerals precipitate out a solution to form mineral deposits called ‘chimneys’. These porous rocks provide habitats for a plethora of new heat-loving microbes, thermophiles.

Using a combination of genomic, ecological and microbiological approaches, Dr. Reysenbach will provide insights into how the geology and geochemistry at the deep-sea vents helps drive the diversity of microbes in these systems, and has led to the discovery of many novel branches on the Tree of Life. Many of these organisms have potential medical and industrial applications, and help inform us better when looking for signs of life elsewhere in the Solar System.
