The World Of Science
Outside of the laboratory, she regularly participates in educational outreach in the local schools through Career Day, tutoring, science demonstrations and Junior Achievement programs. Dr. des Etages is also a supporter of Writers Block Ink, an organization that helps instill drive in young people through creative pursuits. Additionally, she enjoys photography, painting, and gardening, and even plays a little piano.
Question: What skills contribute to your scientific process?
Shelley des Etages: I think that I work well with others. I'm one of five siblings, and I'm one of a generation of 28 cousins. And I'm the eldest girl in that generation of 28 cousins, so when it comes to pulling folks together and working well together with a vast array of personalities, backgrounds, experiences, that's something I draw on and I bring to work as a skill. When we're sitting down with a team and we've got the statistician. We've got the computational biologist. We've got the chemist. We've got the TA biologist who specializes in a disease area. We've got the folks who specialize in looking at how the body processes drugs. It's an array of different backgrounds, and to be able to work with that group and ask, "What are the key important things we need to know from your expertise and your perspective? And can we really communicate clearly to each other what are the important factors and why we need to take different aspects and ideas into account and then come together to have this one product, this experiment, these pearls that we bring together and say, "Okay, we're going to test this, get an answer. Based on that answer, Ivy can do this. Sue can do that. Becky can do this. Tom can do that." And we can all move forward.

If you want to know what makes a Canadian lynx a Canadian lynx a team of DNA sequencers has figured that out.
- A team at UMass Amherst recently sequenced the genome of the Canadian lynx.
- It's part of a project intending to sequence the genome of every vertebrate in the world.
- Conservationists interested in the Canadian lynx have a new tool to work with.
If you want to know what makes a Canadian lynx a Canadian lynx, I can now—as of this month—point you directly to the DNA of a Canadian lynx, and say, "That's what makes a lynx a lynx." The genome was sequenced by a team at UMass Amherst, and it's one of 15 animals whose genomes have been sequenced by the Vertebrate Genomes Project, whose stated goal is to sequence the genome of all 66,000 vertebrate species in the world.
Sequencing the genome of a particular species of an animal is important in terms of preserving genetic diversity. Future generations don't necessarily have to worry about our memory of the Canadian Lynx warping the way hearsay warped perception a long time ago.

It is easy to see how one can look at 66,000 genomic sequences stored away as being the analogous equivalent of the Svalbard Global Seed Vault. It is a potential tool for future conservationists.
But what are the practicalities of sequencing the genome of a lynx beyond engaging with broad bioethical questions? As the animal's habitat shrinks and Earth warms, the Canadian lynx is demonstrating less genetic diversity. Cross-breeding with bobcats in some portions of the lynx's habitat also represents a challenge to the lynx's genetic makeup. The two themselves are also linked: warming climates could drive Canadian lynxes to cross-breed with bobcats.
John Organ, chief of the U.S. Geological Survey's Cooperative Fish and Wildlife units, said to MassLive that the results of the sequencing "can help us look at land conservation strategies to help maintain lynx on the landscape."
What does DNA have to do with land conservation strategies? Consider the fact that the food found in a landscape, the toxins found in a landscape, or the exposure to drugs can have an impact on genetic activity. That potential change can be transmitted down the generative line. If you know exactly how a lynx's DNA is impacted by something, then the environment they occupy can be fine-tuned to meet the needs of the lynx and any other creature that happens to inhabit that particular portion of the earth.
Given that the Trump administration is considering withdrawing protection for the Canadian lynx, a move that caught scientists by surprise, it is worth having as much information on hand as possible for those who have an interest in preserving the health of this creature—all the way down to the building blocks of a lynx's life.
The exploding popularity of the keto diet puts a less used veggie into the spotlight.
- The cauliflower is a vegetable of choice if you're on the keto diet.
- The plant is low in carbs and can replace potatoes, rice and pasta.
- It can be eaten both raw and cooked for different benefits.
Great again? Why America stopped looking forward to the future
- Income inequality is dividing Americans.
- Wages haven't risen in 30 years, while prices for housing, schools, and basic goods has.
- Canny (and uncanny) politicians have learned how to milk the politics of fear by comparing the present to the past.
