Spring Neighborhood Science at Howson Branch Library

Science Under the Stars has expanded to include the Austin Public Library! At Neighborhood Science, previous SUTS speakers will present at different library branches around the city a couple times a month. Below are the dates and descriptions for this fall at the Howson Branch Library, 2500 Exposition Blvd, Austin, TX 78703. All talks begin at 7:30pm. **These talks will be held outdoors, so bring a chair and dress accordingly! Talks will be moved indoors in case of inclement weather.

February 25th at 7:30pm: Francisco Llauger – “Through Claws and Scales: Reptiles, Conservation, and Iguanas of the Caribbean”
Reptiles are often among the most misunderstood animals walking, crawling, and slithering across our planet, but I’ve always seen nothing but fascinating beings that deserve our respect. I’ve led my life trying to study these creatures, and now I invite you to take that journey with me as we look at why these animals need our protection and look at a unique group of lizards nestled across the white sand beaches of the Caribbean-Cyclura, the most endangered lizards in the world!

March 31st at 7:30pm: Tristan Kubik – “Fermented fantasia: a leavenly evening sure to spoil you rotten!”
Planet Earth is infested with germs. They coat everything from the surface of our skin to the machines we use, and yes, even the food we eat. Some of these germs can make us sick, some disgust us with their putrid byproducts, while still others poison the very air we breathe. But hiding amidst these tales of illness and foul decomposition is a love story of epic proportions. Amidst the fray of villainous viruses, bad bacteria, and insidious fungi are a few unsung heroes and gifted culinary artisans. What happens when animals break bread with these good microorganisms? What possibilities are unlocked when two unlikely allies team up and turn terrible into terribly wonderful. Together we’ll embark on an unexpectedly delicious adventure. Join me for a leavenly evening as I relate one of the world’s lesser-known love stories, a tale of deliberate food spoilage we affectionately refer to as fermentation!

April 28th at 7:30pm: Anne Chambers – “Slithering serpents: biodiversity, natural history, and common misconceptions of snakes”
Do snakes really dislocate their jaws while feeding? How can you tell if a snake is dangerous? Are all snakes deaf? How did snakes evolve and what role do they play in an ecosystem? Get the answers to these questions and more during an evening exploring everything to do with snakes!

May 19th at 7:30pm: Isaac Miller-Crews – “Animal brains”
How do animal brains evolve? Come take a dive into neuroscience, looking at how animals (including humans!) use their brains. We will examine what is different and what seems to stay the same across a wide range of species.

Spider Silk: An Extraordinary Biomaterial

Known for its incredible strength and elasticity, possible human uses for spider silk currently range from the manufacturing of bulletproof vests, to the suturing of wounds, to the fabricating of elegant ball gowns, and on. But, how and why do spiders create and use this fascinating material in the natural world? And how can we possibly harvest tons of silk from spiders to use in the mass production of goods? To gain insight into these topics, come on out to the next Science under the Stars! (Caution: For those who are not arachnid-inclined, this talk will contain many images and video clips of spiders. Given that, we encourage anyone who is afraid of spiders to come learn more about these awesome creatures; perhaps we can convince you that they are, in fact, not so scary, and sometimes even adorable!).

 

Science Under the Stars is a free public outreach lecture series in Austin, Texas. Events start at 7:00pm outdoors at Brackenridge Field Laboratory, 2907 Lake Austin Blvd, Austin, Texas 78703. Arrive early for refreshments and fun activities for kids of all ages! Guided tours of the field lab are available (wear sturdy shoes and bring water)!

Light Bright: Fluorescence and Chemiluminescence Lighting New Paths in Biology and Technology

Join us as Chintan Modi explores how scientists continue to find novel uses for biofluorescent and biochemiluminescent molecules and use them to gain insight into the inner workings of biology and chemistry! Science Under the Stars is a free public outreach lecture series in Austin, Texas.

In nature, we see organisms put on beautiful light shows, glowing through the use of specialized proteins. Proteins that glow are called biofluorescence and biochemiluminescence molecules, which were discovered over 50 to 60 years ago. These proteins with their unique properties have enabled us to visualize biological processes in a live cell and an organism. Today we can color each individual neuron of a mouse with different fluorescent proteins, or we can use fluorescent proteins to observe how pathogenic bacteria grow in a bio-film. The use of these light-producing biomolecules as biotechnology tools revolutionized the biological sciences in the past 20 years, which was recognized by the 2008 Nobel Prize in chemistry.

Chintan Modi is a graduate student in Cell and Molecular Biology at the University of Texas at Austin.
