The Science of Stroke

Join us for our May Café, as Dr. Tanya Warwick discusses the Science of Stroke.

Dr. Warwick works at the Community Regional Medical Center as Medical Director of the Stroke Program, and is currently researching prevention techniques for people who have already experienced a subcortical stroke and prevention of the onset of heart attacks and strokes by targeting insulin resistance among patients who have experienced a stroke or TIA.

As with previous Café Scientifique presentations, we will be at Café Via, with dinner beginning at 6pm and the presentation at 7pm. Below is a pdf link and jpeg poster of May’s presentation.

Chemical-weathering rates of aquifers and soils: using sediment-age-dating and geochemical mass-balance techniques to understand how groundwater gets its geochemistry

Hey Cafénistas…this is not an April Fool’s joke!

Come join us for Café Scientifique April 1, 2013 with Beth Weiman as she discusses her research that examines how groundwater attains its geochemistry. An important aspect of sourcing and maintaining our water supply deals with understanding how usable fresh-water resources gain their natural geochemistries.  In not knowing from exactly where groundwater is gaining its geochemistry, the goal of this work tries to identify from where groundwater is gaining most of its geochemistry.  In South and Southeast Asia, where many developing countries have natural arsenic contamination in their groundwaters, some work suggests that arsenic is sourced from an aquifer’s overlying soils, while others surmise it to be due to weathering of the underlying aquifer matrix. Based on past research showing that “younger” material weathers faster than “older” material, one objective of this work was to test whether aquifer age was a determinant parameter in arsenic groundwater chemistry.

We will continue to meet at the Cafe Via, near Herndon and Blackstone, where dinner will be served from 6:00 PM onwards, with the talk to begin at 7:00 PM.

ALPR1-SL1: The Accident that Never Should Have Happened

Hey Cafénistas…Forget March Madness!

Come join us for Café Scientifique March 4, 2013 as Owen Gailar discusses the first nuclear reactor accident in the U.S. The  SL-1  reactor,  originally  named  Argonne  Low  Power  Reactor,  ALPR,  was designed  for  the  USA  Army  as  a  prototype  of  a  low-power,  300  kWe  boiling-water reactor plant to be used in geographically remote locations.  The SL-1 was accidentally destroyed in a prompt criticality accident caused by the accidental  ejection  of  a  control  rod  during  maintenance  operations,  followed  by a steam explosion causing the death of four people on January 3, 1961.

We will continue to meet at the Cafe Via, near Herndon and Blackstone, where dinner will be served from 6:00 PM onwards, with the talk to begin at 7:00 PM.

Water usage and landscape decision-making in the Fresno/Clovis area, on Feb 4, 2013

Greetings fellow Cafénistas!

Join us on February 4th for a look at an issue close to home! Dr. Andrew R. Jones, of the Department of Sociology at CSU—Fresno will tell us about research findings from the social survey and site visits conducted as part of the ongoing examination of water usage and its impacts on biodiversity in the Fresno/Clovis Metropolitan Area conducted by ULTRA-FACES (Urban Long Term Research Area – Fresno And Clovis Ecosocial Study). What are potential barriers to people modifying their landscapes and water usage along lines of sustainability? Come to Monday’s presentation and Dr. Jones will provide some insights he and his colleagues have uncovered.

We will continue to meet at the Cafe Via, near Herndon and Blackstone, where dinner will be served from 6:00 PM onwards, with the talk to begin at 7:00 PM.

Dive into the ocean to discover and learn from deep sea Foraminifera, on Jan 7, 2013

Happy New Year, fellow Cafénistas!

Join us on January 7th for an expedition into the deep seas! Dr. Mathieu Richaud, of the Department of Earth and Environmental Sciences at CSU—Fresno will tell us about research into the bottom of the sea where oceanographers take core sediment samples and bring up the myriad and endlessly fascinating little microorganisms called the Foraminifera. What can these deep sea sediment samples and the tiny Foraminifers buried within them tell us about such closer-to-surface phenomena as Sea Level Change, El Niño, and Ocean Acidification? A lot, it seems, as Dr. Richaud will show us in his presentation.

We will continue to meet at the Cafe Via, near Herndon and Blackstone, where dinner will be served from 6:00 PM onwards, with the talk to begin at 7:00 PM.

Cities and Biodiversity Outlook – a global assessment, on 3 Dec 2012

Cities have now become humanity’s preferred habitat on earth, with more than half of us living in urban areas. The ecological effects of cities extend well beyond their geographical boundaries. How much biodiversity do our cities contain? What ecosystem services do cities depend upon, and what ecosystem services can urban habitats generate? What role can cities play in the sustainable management of ecosystems and preservation of biodiversity worldwide? The United Nation’s Convention on Biological Diversity (CBD) recently commissioned the first global assessment of urban biodiversity and ecosystem services: the Cities and Biodiversity Outlook (CBO). The first part of this ongoing assessment—CBO: Action and Policy–was released on 15 Oct 2012 at the Conference of Parties to the CBD in Hyderabad, India. Dr. Madhusudan Katti, one of the lead authors of the CBO, will present an overview of the assessment, sharing the key messages and the science underlying this assessment.

Mark the date in your calendar – this talk will be on 3 Dec 2012. We will meet at Cafe Via near Blackstone & Herndon in north Fresno, where dinner will be available from 6:00Pm onwards, and the presentation will begin at 7:00 PM. You can download the flyer in PDF form embedded below. Please feel free to share this with your friends and join us for another lively evening of science conversation!

Meet Your Neighbors – with David Hunter on 5 Nov 2012

It will be the night before the big election. A good time to get together and meet some of your neighbors, don’t you think? Except the neighbors David Hunter will introduce to us are ones that we may be living among for most of our lives without really noticing they are even there!

David is part of the Meet Your Neighbours Project: A grassroots photography campaign to raise awareness about local wildlife and plants.More than 40 people in over 30 locations around the world are working with Meet Your Neighbours to photograph local plants and animals in a unique way. David’s show will highlight some of the many plant & animal images he has taken for the project, from 12,000 feet up to 100 feet down underground, all photographed in the greater Fresno area.

See everything from endangered animals to common plants in a way that you have never seen them before!

The Great Pacific Garbage Patch – The Science Behind the Hype on Oct 1, 2012

Hello friends!

After a slightly longer than usual summer hiatus, we are coming back on October 1, 2012, with an exciting presentation by Miriam Goldstein, a dynamic young researcher from the Scripps Institution of Oceanography. She will tell us about her pioneering work on the evolutionary ecology of organisms living in the so-called (and much hyped) Great Pacific Garbage Patch – the “Texas-sized” patch of “soup”, made up of the plastic flotsam and jetsam of our modern lives, caught in the great gyre churning in the middle of the Pacific ocean. Miriam is about to complete her Ph.D. and will soon move into a postdoctoral career where she intends to bring her scientific expertise to bear on shaping policy for ocean conservation. She represents a new generation of scientists who, in addition to actually doing great science, are also committed to communicating science to everyone inside and outside the ivory tower, telling great stories through online and offline media avenues. You may want to read (if you haven’t discovered it already) Miriam’s writing on the fantastic Deep Sea News blog. You can also find her regularly on twitter. This is a talk you are not going to want to miss!

Here’s the abstract of her talk:

While plastic pollution is found throughout the world’s oceans, the North Pacific Subtropical Gyre, a remote area nestled between the trade winds and the westerlies, has been dubbed the “Great Pacific Garbage Patch.” Plastic pollution was first detected in this area in the early 1970s and has since become a matter of scientific and public concern. I will present data on the true nature of the “Garbage Patch,” including abundance, distribution, and size of plastic particles. I will also discuss how plastic particles interact with pelagic invertebrates, such as by being directly ingested, acting as a surface for oviposition, and transporting nonindigenous species. Though the large-scale ecological ramifications of open ocean plastic pollution remain unclear, the public is extremely concerned about this issue. I will therefore conclude with my experiences using social media to correct misconceptions and communicate science to broad audiences online.

You can view and download the poster for the event below the fold. Note that we are also trying out a new venue for October’s Café. We will be at the new Cafe Via at the intersection of Blackstone and Herndon avenues in north Fresno.The street address and telephone number are included in the flyer below.

As always, please share this announcement among your friends, and drag them along for what should be fun evening! We look forward to seeing you there to kick of our exciting 6th season.
