Biotechnology Teaching Online: A New Way to Look at Scientific Notebooks

Posted on by Promega

This post is written by guest blogger, Peter Kritsch MS, Adjunct Instructor BTC Institute.

When I was in the middle of my junior year in high school, my family moved. We had lived in the first state for 12 years. I had gone to school there since kindergarten. Although it wasn’t a small district, I knew everybody and, for better or worse, everybody knew me. Often the first reaction I get when I tell people when we moved is that it must have been hard to move so close to graduation. The reality is . . . it really wasn’t. In fact, it was quite liberating. See, I didn’t have to live up to anybody else’s expectations of who I was based on some shared experience in 2nd grade. I had the opportunity to be who I wanted to be, to try new things without feeling like I couldn’t because that wasn’t who I was supposed to be. 

As long as I refrained from beginning too many sentences with “Well at my old school . . . “ people had to accept me for who I was in that moment, not for who they perceived me to be for the previous 12 years. Now, the new activities were not radically different. I still played baseball and still geeked out taking AP science classes, but I picked up new activities like golf, playing basketball with my friends, and even joined the yearbook. I know . . . “radically different.”  The point is that the new situation allowed me to try something new without worrying about what had always been.

The pandemic has forced a lot of us to move our classrooms online. In a short period of time, everything changed about how education was done. Our prior teaching experience, including the experience I had with doing blended learning (ooops . . . “back at my old school”), was helpful to a point.  But we quickly found out that being completely virtual was different. And as science teachers, how do you do more than just teach concepts when online? How do you help students to continue engaging in the crucial parts of science – observing, questioning, designing, analyzing, and communicating?

Screen Media in the Time of COVID-19: Should You Be Reading this Blog?

Posted on by Michele Arduengo, PhD

Screen Media. Cell phones. Social media accounts. If you are a parent, you have probably discussed rules of engagement with your children about these things. All of our modern social media platforms are designed to keep us engaged with them by showing us the latest post, the next video or the people now online. Work emails give us notifications when something arrives in our Inbox. Business software platforms like Microsoft Teams send us notifications whenever someone comments in a conversation we have ever been part of. There are many siren signals pulling us toward our screens.

Enter COVID-19, the flu-like illness caused by the SARS-CoV-2 virus that has already claimed the lives of 210,000 people in the United States, and leaving countless others permanently affected by other long-term health consequences. Spread by aerosol, COVID-19 is most dangerous in places where lots of people congregate in a small area, particularly if they are talking to each other. Consequently, office buildings are empty as many of us work or go to school remotely.

Before COVID-19, if I had a day full of meetings at work, I was running from conference room to conference room, two miles, uphill, in the snow between buildings. Now, a day full of meetings means sitting in front of a computer monitor, trying to figure out how I will get any kind of break between calls. The average number of steps recorded by my pedometer has decreased markedly since March when our remote work started.

Technology has been an incredible blessing during this pandemic—allowing us to continue to work and stay connected with friends and family. Technology is the only way that some people can connect with loved ones in long-term care facilities. It allows students to continue learning through remote classrooms and chats.

But what has been the effect of the increased time spent on screens during this pandemic?

Answers to the Most Common Questions from “Battling the Novel Coronavirus” Online Event

Posted on by Promega

This post was written by guest blogger, Nitin Kapoor, from our Promega India branch office.

The COVID-19 crisis has led to substantial worldwide efforts to develop drug treatments and vaccines effective against SARS-CoV-2.  Termed a novel Coronavirus, SARS-CoV-2 belongs to the same family as that of SARS (severe acute respiratory syndrome) and MERS (Middle East respiratory syndrome) viruses that were responsible for epidemics in 2003 and 2012 respectively (Lu et al. 2020)

A Virtual Visit with the National Young Researcher of the Year

Posted on by Jordan Villanueva

Gayetri Ramachandran taught her first university class during the COVID-19 pandemic. While the online course was successful overall, it was a strange experience to teach without being able to see the students.

“If you’re giving a seminar and you can’t see the other person, it’s extremely difficult,” says Gayetri, a postdoctoral researcher at the Institut Necker Enfants Malades in Paris, France. “If they’re sleeping, I can’t see them. It’s fine, you can sleep, but if I can’t see that you’re sleeping, then I can’t get that feedback in real time.”

Earlier this summer, Gayetri had another opportunity to give an online presentation. Before the COVID-19 pandemic disrupted travel plans, she was scheduled to visit the Promega Headquarters in Madison, WI, to tour the facilities and meet with R&D scientists. Instead, Gayetri presented her research to a group of Promega scientists in the first Promega Virtual Customer Experience Visit.

Celebrating the Work of Women Scientists on the 100th Anniversary of Rosalind Franklin’s Birth

Posted on by Michele Arduengo, PhD

Photo 51 is the now-famous X-ray diffraction picture that allowed Watson and Crick to crystalize centuries work of scientific study (from Mendel to Chargaff) into a viable structural model that explained how DNA could serve as the material of the gene. The photo was painstakingly produced by Dr. Rosalind Franklin, a contemporary of Watson and Crick. Although she and her colleague R.G. Gosling did publish their work in the same issue of Nature as the Watson and Crick paper (1,2), their work did not receive the same public accolades of that of Watson and Crick.

Applications Scientists help partners and customers apply existing technology to new questions. Read more about their work.

Women scientists have been contributing to our understanding of the world around us throughout history. On this 100th anniversary of Dr. Rosalind Franklin’s birth, we want to take a little time to recognize the work that women scientists are doing at Promega.

How to Start Writing a Scientific Manuscript

Posted on by Promega

Today’s blog is adapted from a presentation by Danette Daniels, PhD, in our webinar “Writing About Science: Tips and Tricks for Communicating Your Research.”

As scientists, we can do science forever. The beauty about science is that the questions never end – we can keep asking, and every time we find an answer, we have a new direction to pursue. But it’s very important to know when it’s time to write up your results.

Publishing may be connected to leaving or transitioning your position, but at all times you should be thinking, “What is my end goal? What is the big question I want to answer? What are the questions the field has about my research?” As you reach milestones and make discoveries, whether big or small, consider whether you will have a complete and compelling story to tell in the end.

Marine animals are fascinating. Not only are their appearances alien-like (think tentacles, suckers and bioluminescence). But many have also developed unique capabilities unlike anything you see on land.

In fact, most of the biodiversity of the world lies beneath the ocean. According to the World Register of Marine Species, there are more than 400,000 marine species, and it is estimated that 91% of marine species have yet to be identified. Studying marine animals may help us learn more about how we evolved and even lead to new ways to study and treat human diseases. At the forefront of marine biology research is the Marine Biological Lab (MBL), located in Woods Hole, Massachusetts.

Editing for Rhythm and Flow in Writing

My first project, a scarf for "Floppy Dog".

Updated 5/14/2020

For a while now I have made a living knitting words, stringing them together with a rhythm and flow to create a finished piece that has some kind of meaning. Recently I started learning how to knit yarn together with a rhythm (ideally) that will bring the loops and knots together into some kind of finished whole that has meaning: a scarf, a hat, a dish rag. And just like the clacking of knitting needles can relax and de-stress you, the clicking of the keyboard when your writing is in rhythm can be a joyful experience.

The rhythm and flow of language is important in all types of writing, including scientific writing. If your language has a consistent rhythm and flow, chances are your reader will be more likely to understand it on a first read.

Enhancing Creativity: The Promega Employee Art Show 2020

Posted on by Kari Kenefick

What hangs in the hallways of your workplace? Advertising? Awards? Commercially-sourced artwork? The Promega campus in Madison, WI, is composed of eight buildings. In many of these buildings you’ll find all of the above.

But as you enter the atrium of the BTC (Biopharmaceutical Technology Center) building where the Employee Art Show hangs, you’re greeted by handmade, homemade artwork, including drawings, ceramics, paintings, photographs and quilts.

Promega employees examine artwork in the BTC during the 2020 Employee Art Show opening.

These art pieces hold the distinction of being created by talented Promega employees, their families and friends. The annual Promega Employee Art Show opened Friday, January 17, with approximately 150 works displayed, including pieces created by parents of employees, employees and their children. These art pieces are on display to the public through the end of February 2020.

A Crash Course in CRISPR

Posted on by Darcia Schweitzer

CRISPR is a hot topic right now, and rightly so—it is revolutionizing research that relies on editing genes. But what exactly is CRISPR? How does it work? Why is everyone so interested in using it? Today’s blog is a beginner’s guide on how CRISPR works with an overview of some new applications of this technology for those familiar with CRISPR.

Introduction to CRISPR/Cas9

27850283-June-13-CRISPR-image-WEB

Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) were discovered in 1987, but it took 30 years before scientists identified their function. CRISPRs are a special kind of repeating DNA sequence that bacteria have as part of their “immune” system against invading nucleic acids from viruses and other bacteria. Over time, the genetic material from these invaders can be incorporated into the bacterial genome as a CRISPR and used to target specific sequences found in foreign genomes.

CRISPRs are part of a system within a bacterium that requires a nuclease (e.g. Cas9), a single guide RNA (sgRNA) and a tracrRNA. The tracrRNA recruits Cas9, while sgRNA binds to Cas9 and guides it to the corresponding DNA sequence of the invading genome. Cas9 then cuts the DNA, creating a double-stranded break that disables its function. Bacteria use a Protospacer Adjacent Motif, or PAM, sequence near the target sequence to distinguish between self and non-self and protect their own DNA.

While this system is an effective method of protection for bacteria, CRISPR/Cas9 has been manipulated in order to perform gene editing in a lab (click here for a video about CRISPR). First, the tracrRNA and sgRNA are combined into a single molecule. Then the sequence of the guide portion of this RNA is changed to match the target sequence. Using this engineered sgRNA along with Cas9 will result in a double-stranded break (DSB) in the target DNA sequence, provided the target sequence is adjacent to a compatible PAM sequence.
