I’m so happy that my high school sophomore year is over, and I did great on my finals!

In my English class, our final was mostly over the last two books that we read: All Quiet on the Western Front and Great Expectations. In my world history class, I enjoyed writing a “changes in continuity over time” essay about Europe. I talked about the Roman empire through the Medieval era to the modern day.

UT Environmental Science Institute

In my last blog post, I shared my pictures from the UT Austin Environmental Science Institute Education and Outreach Dinner at the Google Fiber Space on April 29, 2015.

I’m a big fan of the UT Environmental Science Institute (ESI) because they have an awesome program called Hot Science – Cool Talks, where they bring scientists and researchers to talk about hot (of course) science topics each fall and spring semester. The presentations are geared to kids from kindergarten (which I was in at one time) to high school students, but even adults will find the talks and activities before the presentation both fun and interesting.

The last Hot Science Cool talks of the Spring 2015 semester on May 1, 2015, was Better Living Through Microbes by Dr. Lydia Contreras, UT Austin Assistant Professor of Chemical Engineering. I previewed her talk in my previous blog post.

Dr. Contreras talked about microbes that could live in toxic environments, and I was fascinated to learn about Deinococcus radiodurans, a bacteria that could survive high doses of radiation.

Scientists discovered this unique bacteria after they irradiated meat for sterilization. The radiation should have killed all the bacteria in the meat, but they discovered that the irradiated meat spoiled after a few days.

Scientists were baffled, and after they investigated, they discovered this new bacteria. In addition to radiation, it can also withstand most cold, dehydration, vacuum, and acid! Because of its hardiness, it also has the nickname, Conan the Bacterium.

How does the bacteria resist radiation?

Dr. Contreras’ is researching the DNA of the bacteria along with its cell composition to understand how it is able to withstand lethal doses of radiation that would kill all other bacteria. These radiation levels are also fatal to humans.

Somehow the bacteria can repair the damage that radiation causes to its DNA. Note however that Deinococcus radiodurans is not immune to radiation. There is a high enough level of radiation that can kill the bacteria.

From her research, we may be able to understand how to protect or repair cells from the harmful effects of radiation. (I learned more about radiation and half-lives in one of the last chapters that we covered in my sophomore high school chemistry class.)

Microbes have been in the news a lot lately, usually as part of a video or story about the problems they cause, as with the case of Listeria in ice cream.

Listeria is a terrible bacteria that lives in soil and water and can spread to and thrive in food processing plants. Getting rid of Listeria requires cooking and pasteurization, which helps before food is cooked, but not afterwards when it’s packaged. Listeria is hard to eliminate because it grows in cold temperatures.

But not all microbes are bad. Many, in fact most, are actually good.

As part of his TED talk, microbiologist Dr. Jonathan Eisen talks about how microbes play a role in our defense, boost our immune system, protect our auto-immune system, fight off stress, and more. In addition to Dr. Eisen’s video, here are more sites to help you learn about the benefits of microbes:

Microbes are all around us, and researchers are studying how microbes live and evolve to see how they can benefit us, such as to improve our health or create new products.

Dr. Lydia Contreras and her research group are studying how microbes live in toxic environments. (Dr. Contreras is an Assistant Professor, Chemical Engineering, at the University of Texas at Austin (UT Austin).) What they discover could help build new molecules to act as early warning systems for preventing disease.

Learn about the benefits of microbes with Dr. Contreras at the next Hot Science – Cool Talk presentation, Better living through microbes, on Friday, May 1, 2015. The lecture starts at 7:00 pm in the Welch Hall Auditorium on the UT Austin campus. Be sure to get there early because the community science fair with lots of fun activities starts at 5:45 pm.

Chemistry in high school is fun, but I really liked studying biology in high school, and I’m excited about learning more about microbes at this Hot Science – Cool Talks presentation on Friday.

Superstition in Science – UT Austin Hot Science Cool Talk

We really have to thank the ancient Greeks for giving us a lot, including democracy, philosophy, art, and architecture. Science? Well, yes and no. Some of their science was born out of superstition.

They believed in a plethora of gods that had magical powers over them and the environment. Zeus, Hades, and Poseidon were the big three Greek gods who the ancients thought held sway over the land, and indeed their very lives.

But we now know (hopefully) that many of the powers they would have attributed to Zeus were just electricity from thunderstorms.

Since the days of old, our knowledge of science has expanded past superstition. Instead of rolling dice, we use the scientific method to provide an objective and standardized approach to conducting experiments and learning.

A New Age of Enlightenment with Hot Science – Cool Talks

We are studying the enlightenment in my high school world history class. There was an explosion of scientific knowledge and advancements in art and literature during this time period, which was also known as the Age of Reason. This change in Western civilization promoted individualism and thought and reached its peak in Europe in the mid-1700s.

Some of the great scientists during this time period include Nicholas Copernicus who came up with the heliocentric theory of the solar system with the Earth and the planets revolving around the sun.

One of my favorite scientists of the enlightenment is Francis Bacon. He encouraged scientists not to rely on ancient thinkers, but to use experimentation and then draw conclusions. This approach helped to develop the scientific method, which is basically to have a hypothesis, test your hypothesis, get your results, and see if others can copy your experiment and get the same result.

These scientists allowed us to advance past intuition and into reason. An example of intuition is that since frogs live in the mud, they must be made of mud. Also, since rotten meat has maggots, the maggots must be born out of meat. But with the scientific method, we were able to use experimentation to learn that flies lay eggs on rotten meat, and that the maggots just don’t come into existence.

We’re doing a fun activity in class soon. It’s called a salon. Not the beauty one, but one where intellectuals get together and discuss the topics of the day. It originated in France, and the exchange of scientific ideas helped to propel this Age of Reason.

Sadly, intellectual salons are not as common today, but there is something better – Hot Science, Cool Talks, and my friends, we have an opportunity to join a modern day scientific salon on Friday, February 20, 2015, at the University of Texas at Austin.

Dr. Michael Webber will talk about the role of energy in our lives and society, spanning hundreds of years. (Including the enlightenment too?) He’ll bust a few myths on the way and give fun facts on future technologies and solutions.

This Hot Science – Cool Talks event is a part of UT Energy Week and includes a community science fair before the event.

Wouldn’t it be fantastic to talk with the great scientists of our time? Well, you can with Dr. Michael Weber, Dr. Jay Banner, and many illuminating UT Austin researchers and scientists during Hot Science – Cool Talks events. And this month’s presentation about energy is a great way to turn on a new age of enlightenment!

Many researchers are using drones to help find and identify invasive species in those hard to reach places. Here are just a few recent articles about where they are using drones to hunt invasive species:

Learn more about drones with Hot Science – Cool Talks

You can learn more about drones this Friday, November 21, 2014, with the latest Hot Science – Cool Talks presentation, Drones: Myths, Facts, Hacks, and The Future, by Dr. Todd Humphreys, Assistant Professor of Aerospace Engineering and Engineering Mechanics with the University of Texas at Austin.

The presentation starts at 7 pm in Welch Hall, but be sure to arrive early, since fun science activities will start at 5:45 pm!

Dr. Humphreys will talk about how we can use drones in the future and how that may be different from how movies portray drones. He and his team were the first to show how GPS hacking can take over a drone.

The invasive plant Giant Reed (Arundo donax) better be on the lookout!

Periodic Table of Hot Science Selfies

Dr. David Laude's Chemistry Cool Talk at UT Austin

Dr. David Laude’s Chemistry Cool Talk at UT Austin

My friends and I enjoy taking selfies. I enjoy science, and I thought what better way to bring the two together (like an exothermic chemical reaction!) at last month’s Hot Science event about chemistry at UT Austin.

The first Hot Science – Cool Talk of the Fall 2014 semester, How I Learned to Love Chemistry, by Dr. David Laude was packed! There was a huge rainstorm before the event, but that didn’t discourage young and old chemistry enthusiasts from attending in force (F=ma).

I think this is the most people that have ever been to a Hot Science event. If anything, the rain made people more determined to learn, especially with the pre-lecture activities. Everyone came out, including friends that I haven’t seen in years. The entire Welch Hall main auditorium was full with standing room only. What density (D=m/v)!

Many people, including myself, a friend from school, and our chemistry teacher watched the event from the overflow auditorium. (I even arrived early!) Even with the time delay in the video simulcast, Dr. Laude’s talk was enlightening (c=2.9×10^8 m/s).

And now for the chemistry selfies!

Dr. Jay Banner, Director, UT Environmental Science Institute (ESI), is the best!

Theodore Gray’s The Elements book in print and on the iPad is an excellent and fun way to learn about the elements in the periodic table. I’ve used his book to learn more about the elements in my high school chemistry class.

While I’ve enjoyed looking through the printed book, the app is more interactive and offers animations. To help dyslexic readers, I hope that the creators of the app, TouchPress, will publish an update that allows you to highlight portions of the text and use the iOS text-to-speech accessibility feature to have my iPad read the content out loud.

Extreme weather at SXSW Eco

The next Hot Science presentation whirls in next Monday, October 6, 2014, with a special event at SXSW Eco.  Dr. Kevin Klosel will talk about Extreme Weather and Uncertainty in Forecasting.

During this year’s SXSW Eco event, you’ll learn about the science behind extreme weather, like tornadoes and superstorms, and how meteorologists factor in uncertainty.

Sounds like another super Hot Science is on it’s way, and the forecast for selfies with Dr. Klosel are favorable!

Update: Remember that this special event is free and is at the Austin Convention Center (and not at UT Austin.) The National Weather Service is bringing a tornado machine, and you’ll also be able to create lighting with a Van de Graaff machine and erupt snow to create an avalanche. Sounds like lots of fun!

Hot Science and Modern Chemistry in High School

Hooray for Modern Chemistry (and yes, I have a Periodic Table shower curtain)

Hooray for Modern Chemistry (and yes, I have a Periodic Table shower curtain)

I recently started my sophomore year in high school, and my classes have been a lot of fun. As many of you know, I have a great love of biology (and in learning about and battling invasive plant species!), but recently, I found a similar love for chemistry. (I’ll just admit right now that I love science.)

In the first few weeks of my chemistry class, it’s been fascinating learning about the basics of chemistry, including measurements and states of matter.

Volcanoes in Austin, Texas

For our first lab, we mixed acetic acid and sodium bicarbonate and measured the temperature of the mixture. We found that it created an endothermic reaction, which means that the temperature drops as the reaction progresses.

I’ll let you in on a secret. Acetic acid is vinegar, and sodium bicarbonate is baking soda, and this is a common mixture for volcano science fair projects. You just need to add detergent so you can make soap bubbles from the escaping gasses. With a little red food coloring, it looks like lava bubbling!

We’re using a very interesting piece of equipment, the Vernier LabQuest 2. This device is amazing since you can hook up different probes to measure temperature, light, sound, pressure, and even radiation! You can get information on almost everything. It’s a great tool, and one I wish I had at home too.

Modern Chemistry textbook, audiobook, and iBook

Modern Chemistry iBook available from iTunes

Modern Chemistry iBook available from iTunes

We’re using the Modern Chemistry book from Holt, Rinehart and Winston in my class. With my dyslexia, it’s not easy for me to learn from just the printed word. Finding the audio book and iBook for my biology textbook helped me out during my high school freshman year.

I was also able to find the audio version of my current Modern Chemistry book from Learning Ally and a newer version of the Modern Chemistry iBook from iTunes. With Learning Ally, a human reader reads the entire page, including figures. With my iBook version, I can select portions of the text for my Apple MacBook’s or iPad’s electronic voice to read. The iBook version also contains videos, quizzes, and other nice interactive features.

I’ve always loved Hot Science – Cool Talks from the UT Austin Environmental Science Institute (ESI).

Hot Science – Cool Talks are a series of presentations where you can enjoy fun prelecture activities and learn a lot about science during presentations given by distinguished scientists. They’ve become very popular over the years, and I’ve been going to them since I’ve been a little scientist guy.

Thanks to Dr. Jay Banner, UT ESI director, I’ve had the great fortune to interview many of the previous presenting scientists. (Here are some of my video interviews with Dr. Chris Kirk for his Hot Science – Cool Talks presentation, “Your Eye, My Eye, and the Eye of the Aye-Aye”.)

With myself and many other Austin-area sophomores learning about chemistry in science this year, what great fortune that the first Hot Science presentation is on chemistry!

Dr. David Laude will give a presentation on How I Learned to Love Chemistry on Friday, September 12, 2014. The fun prelecture activities start at 5:45 p.m., and Dr. Laude’s presentation starts at 7:00 p.m.

I’m counting on his promise that Dr. Laude will blow stuff up! He’ll make liquid nitrogen ice cream for everyone at the end. See! Science can be fascinating and delicious at the same time.
