Today’s blog is guest-written by Susanna Harris, a graduate student at the University of North Carolina in Chapel Hill.
thing to hear that everything is going to be okay. It’s another to know it and
make it that way.
At the end
of a lab meeting where I had outlined my last of six years getting my PhD, my
advisor announced she would be moving the lab from North Carolina to Massachusetts
in about six months. Just when everything had settled into place, this
announcement turned my bookshelf of plans on its side once again. Suddenly, I
didn’t know what would happen next.
I chose to
go to grad school partly to challenge myself to accept uncertainty. When I
started my PhD in Microbiology in 2014, I thought this would mean reading new
papers and adjusting experiments accordingly. As it has turned out, the real
challenge has been to constantly get back up as life and graduate school knock
me flat on my ass. Yes, I needed strength to power through, but even more than
that, I needed resilience.
Ten years ago, I wrote about the distressing news of lack of genetic diversity in the wild Amur tiger population. International Tiger Day seemed like a good time to check in on what progress has been made to both sustain and establish wild tiger populations worldwide. In 2010, 13 tiger range countries (TRC) committed to a goal of doubling the world’s tiger population by 2022.
That timeline was an ambitious goal, as highlighted by a report published in PLOS One in November of 2018 (1). The authors assessed the recovery potential of 18 sites identified under the World Wide Fund for Nature’s (WWF) Tigers alive initiative. The recovery system has several parts: A source site with higher density of tigers that the area around it and has a legal framework that does (or will) protect the tiger population; a recovery site that has a lower density of tigers than the surrounding regions, has the ability to support more tigers but is not as supported as a source site; and a support region that connects a source and recovery site. These different site types all require different levels of management, available resources and legal protections, but they need to be managed in a coordinated way.
Aside from what is needed to manage these recovery sites, there are also other things that need to exist to support recovery of tiger populations. Some of these include support from local populations and governments, as well as environmental requirements such as breeding habitats and prey populations. For 15 of the 18 sites it is the prey population that is the sticking point. Recovery of prey populations is a slow process. The authors concluded that there need to be a commitment to achieving a realistic recovery of tiger populations, even if we miss the 2022 goal.
The fate of the wild tiger is still tenuous. Only time will tell if the interventions that are being implemented can be realized in time.

Today’s blog brought to you by Julia Nepper, a Promega science writer guest blogging for the BioPharmaceutical Technology Center Institute (BTC Institute)!
“We all benefit from STEM role models. When students from underrepresented populations meet and learn about STEM professionals of color, they can see themselves as the scientists and engineers of the future. Fun, engaging science programming for children is also essential to light the spark for the next generation. A Celebration of Life, the partnership between the BTC Institute and the African American Ethnic Academy, two community nonprofits, has combined these 2 objectives for over twenty years.” according to Barbara Bielec, K-12 Program Director.
This year, the theme of the program is Sunsational!, with a number of activities related to the sun, solar energy, and STEM careers. As part of the program, students heard talks from several STEM professionals of color about their work. Mehrdad Arjmand, co-founder of solar energy company NovoMoto, was one of those speakers.
Dr. Arjmand was born and raised in Iran. His path to becoming a mechanical engineer began as a child, with him “destroying a lot of equipment” in his house. After completing his undergraduate education, he came to the States to pursue a PhD at the University of Wisconsin-Madison, where he met Aaron Olson, a student who was born in the Democratic Republic of Congo. These two discovered a shared passion for starting a business and helping their communities, which led directly to the founding of NovoMoto. The name derives from Portuguese for “new” (novo) and Lingala—a language spoken in Congo—for “fire” (moto). Continue reading “Empowering Communities with the Light of the Sun”
Restriction enzymes recognize short DNA sequences and cleave double-stranded DNA at specific sites within or adjacent to these sequences. These enzymes are the workhorse in many molecular biology applications such as cloning, RFLP, methylation-specific restriction enzyme analysis of DNA, etc. In order to streamline and shorten these workflows, restrictions enzymes with enhanced capabilities are desirable.
A subset of Promega restriction enzymes offer capabilities that include rapid digestion of DNA in 15 minutes or less, ability to completely digest DNA directly in the GoTaq® Green Master Mix, and Blue/White Cloning Qualification which allows for rapid, reliable detection of transformants.
To learn more about restriction enzymes and applications, check out Restriction Enzyme Resource on the web. The resource provides everything from information on restriction enzyme biology to practical information on how to use restriction enzymes. This resource also contains useful online tools to help you use enzymes more effectively. It helps you choose the best reaction buffer for double digests, find the commercially available enzyme that cuts your sequence of interest, find compatible ends, and search for specific information on cut site, overhang isoschizomers and neoschizomers by enzyme name.
For added convenience, you can download the mobile app and use the Restriction Enzyme Tool to plan your next digest.
For additional information regarding Restriction Enzyme Digest, reference the supplementary video below.
Buffers are often overlooked and taken for granted by laboratory scientists, until the day comes when a bizarre artifact is observed and its origin is traced to a bad buffer.
The simplest definition of a buffer is a solution that resists changes in hydrogen ion concentration as a result of internal and environmental factors. Buffers essentially maintain pH for a system. The effective buffering range of a buffer is a factor of its pKa, the dissociation constant of the weak acid in the buffering system. Many things, such as changes in temperature or concentration, can affect the pKa of a buffer.
In 1966, Norman Good and colleagues set out to define the best buffers for biochemical systems (1). By 1980, Good and his colleagues identified twenty buffers that set the standard for biological and biochemical research use (2,3). Good set forth several criteria for the selection of these buffers: Continue reading “What Makes a “Good” Buffer?”
Every day at the Promega Headquarters in Madison, Wisconsin, many Promega employees trade the crowded Beltline Highway for a scenic route along the bike trails. As our colleagues wind around the lakes and prairies of south-central Wisconsin, they’re reducing greenhouse gas emissions and getting some fun exercise in the process. This week, during National Bike-to-Work week, we’re taking time to recognize our colleagues who opt for a healthier and more sustainable commute. In the video below, hear about how Promega supports our bike commuters from Sam Jackson, an avid biker and Multimedia Specialist at Promega.
g Force or Relative Centrifugal Force (RCF) is the amount of acceleration to be applied to the sample. It depends on the revolutions per minute (RPM) and radius of the rotor, and is relative to the force of Earth’s gravity.
A good, precise protocol for centrifugation instructs you to use the g force rather than RPMs because the rotor size might differ, and g force will be different while the revolutions per minute stay the same. Unfortunately, many protocols are written in hurry and instructions are given in RPMs. Therefore, you have to convert g force (RCF) into revolutions per minute (rpms) and vice versa.
Modern centrifuges have an automatic converter but older ones do not. There is a simple formula to calculate this, but it takes some time to do the calculation. Meanwhile, your cells might die or the biochemical reaction goes on for three times longer than it should.
