With experiments, comes waste: Scientific waste and where it ends up

Written by: Lirong Shi and Manaswini Sarangi

Introduction

As a scientist working around scientists, we may not realize how much scientific waste we and our colleagues produce every day, just like everyone else who may not pay attention to how much household waste we produce in our kitchen. We are so used to the waste in the lab, and compared to the large garbage bin outside, we might think the small plastic bucket in the lab should be negligible. But that is not true. Accounting for only 0.1% of the population, scientists create approximately 5.5 million tons of plastic waste annually in life science alone, which accounts for approximately 2% of the plastic waste produced worldwide [1]. The large amount of plastic waste wandering around the oceans can disrupt carbon balance, poison fish, and end up on humans’ tables. Through experiments, scientists are attempting to improve everyone’s life while also literally contributing to the detriment of the world.

When venom becomes your painkiller

Imagine you are not in frigid Michigan but are swimming in the warm waters of the Caribbean. The warm waters caress your skin. While you dive past a colorful reef with a plethora of fish, you see an anemone. You know you cannot touch it, because it might sting you with its toxins. Little do you know; these anemones are not the only ones capable of stinging. The reef harbors a far deadlier and more beautiful creature: cone snails. While cute on the outside, these little creatures can contain a venom cocktail of more than 100 toxins.  However, if they do sting, you will not feel any pain at all. This prompted a pivotal change in Professor Baldomero Olivera’s career. Dr. Olivero is a researcher currently at the University of Utah, where he transitioned from studying DNA synthesis to studying cone sails indigenous from his hometown in the Philippines.

The Quantum Quandary

Author: Kristina Lenn

Editors: Alex Taylor, Zuleirys Santana-Rodriguez, and Whit Froehlich

My absolute favorite movie is The Imitation Game with Benedict Cumberbatch and Keira Knightley, and I love this movie for these reasons:

  1. The lesson of not giving in to naysayers is showcased throughout the movie.
  2. As a computationalist, I am proud to see my field obtain more visibility in the public eye.
  3. And duh – Benedict Cumberbatch!

However, one of my favorite scenes in the movie is when school-age Alan Turing is walking with his only friend, Christopher. Alan’s perceived oddities make him a target of ridicule among his classmates, but Christopher makes this very poignant statement: “Sometimes it is the people no one imagines anything of who do the things that no one can imagine.” Continue reading “The Quantum Quandary”

MARVELous Solar Cells

Spoiler: For a better reading experience, make sure to see the amazing Doctor Strange!


I love Marvel movies, and they’re even more fun to watch as a scientist. In many of them, some energy source is at risk of falling into the wrong hands. Lest the source destroy not only the planet but also the entire galaxy, a bunch of unlikely misfits band together to ensure the energy source’s safety and security. The power source in question is something that has the paradoxical capability of both sustaining and destroying life, like the sun. Extraterrestrial battles take place with the brutish Hulk and the witty turbo-powered Iron Man. (Or, if you prefer Guardians of the Galaxy, you can fight with the smart-aleck Rocket and the cute-yet-somewhat-airheaded Groot.) The bad guys want to use this energy to have unlimited power; the good guys want to harness the energy in a more controlled manner.

La separación de agua: Una manera para almacenar energía solar

Escrito en inglés por Jimmy Brancho, traducido al español por Jean Carlos Rodriguez-Díaz y editado por Thibaut R. Pardo-García

La fuente de energía del futuro puede ser mucho más familiar de lo que piensas.

Muchas personas están emocionadas por el remplazo de combustibles fósiles por energía solar.
La recolección, tratamiento y quema de combustibles fósiles es uno de los mayores contribuyentes a la contaminación ambiental y conflictos políticos. ¿Podremos reducir estos problemas al usar energía solar? Al parecer, eso es lo que piensa la industria. La estadística más reciente del National Renewable Energy Laboratory Data Book demuestra que la cantidad de energía producida por instalaciones solares ha estado creciendo continuamente en la última década- casi un 75% de 2011 a 2012.

¿Qué se hace cuando el sol se acuesta? ¿Se supone que dejemos de ver Netflix por la noche?

Trasplante de Órganos de Cerdos a Humanos Podría Ser Posible en el Futuro Gracias a la Ingeniera Genética

Escrita por Attabey Rodríguez Benitez y editado por Cristina Maria Rios.

¿Te imaginas un futuro en el que los humanos podamos recibir órganos de animales en lugar de esperar por un donante? Esto podría ser posible gracias a una investigación llevada a cabo por una colaboración internacional entre laboratorios de Harvard y China que resultó en una publicación en la revista científica Science.

Can you imagine a future where humans could receive organs from animals instead of having to wait for a donor? Well, this could be possible thanks to evidence from an international collaboration between labs in Harvard and China which resulted in a publication in the prestigious journal Science.

Computing Levinthal’s Paradox: Protein Folding, Part 2

Author: Sarah Kearns

Editors: David Mertz, Zuleirys Santana Rodriguez, and Scott Barolo

In a previous post, we discussed how proteins fold into unique shapes that allow them to perform their biological functions. Through many physical and chemical properties, like hydrogen bonding and hydrophobicity, proteins are able to fold correctly. However, proteins can fold improperly, and sometimes these malformed peptides aggregate, leading to diseases like Alzheimer’s.

How can we figure out when the folding process goes wrong? Can we use computers to figure out the folding/misfolding process and develop methods to prevent or undo the damage done by protein aggregates?

De-coupling the GMO-glyphosate link

Author: Amira Aker

Editors: Brittany Dixon, Kevin Boehnke

Tinkering with an organism’s genes is the subject of one of the most controversial debates today – and rightfully so. The resulting organisms are commonly referred to as genetically modified organisms (GMOs), and figuring out how to use GMOs in a safe and sustainable manner is hotly debated. This issue isn’t simply a matter of technology, but one of safety, ecology, economics and even morality. Yet, there has been a notable absence of discussion around the broad-based herbicide glyphosate in mainstream media; namely, that over 80% of GMOs on the market today are modified to tolerate glyphosate. This effective herbicide kills pesky weeds without affecting farmers’ GMO crops, saving time and, potentially, money. However, given the vast opportunities that GMO science opens to us, is dedicating so many resources to this single GMO product the right way to go?

New elements on the block

Author: David Mertz

Editors: Tricia Garay, Irene Park

Ever since an interactive display was built in my high school chemistry lab (one of only six such installations in the world), I’ve found the periodic table of elements to be a fascinating fixture of science. I remember watching the scientists prepare little displays for each individual element, including the metal gallium which they let me hold in my hand. It was different than most of the metals familiar to us. With a melting temperature just below 30 degrees Celsius (86 degrees Fahrenheit), the metallic cube began to melt right on my palm.
