In the wake of a devastating earthquake, assessing the extent of damage to infrastructure is time consuming—now, a cheap sensor system based on the accelerometers in cellphones could expedite this process. Host Sarah Crespi talks with Contributing Correspondent Lizzie Wade about how these sensor systems work and how they might assist communities after an earthquake. In another Earth-shaking study, scientists have downgraded the height of the ancient Tibetan Plateau. Most reconstructions estimate that the “rooftop of the world” reached its current height of 4500 meters about 40 million years ago, but a new study suggests it was a mere 3000 meters high during this period. Host Meagan Cantwell speaks with Svetlana Botsyun, a postdoctoral researcher at Tübingen University in Germany, about her team’s new approach to studying paleoelevation, and how a shorter Tibetan Plateau would have impacted the surrounding area’s climate.

How can you resist puppy dog eyes? This sweet, soulful look might very well have been bred into canines by their intended victims—humans. Online News Editor David Grimm talks with host Meagan Cantwell about a new study on the evolution of this endearing facial maneuver. David also talks about what diseased dog spines can tell us about early domestication—were these marks of hard work or a gentler old age for our doggy domestics? Also this week, host Sarah Crespi talks with Michel Marechal of the University of Zurich in Switzerland about honesty around the globe. By tracking about 17,000 wallets left at hotels, post offices, and banks, his team found that we humans are a lot more honest than either economic models or our own intuitions give us credit for.

This week’s show starts with Contributing Correspondent Lizzie Wade, who spent 12 days with archaeologists searching for a lost Maya city in the Chiapas wilderness in Mexico. She talks with host Sarah Crespi about how you lose a city—and how you might go about finding one. And Sarah talks with Christophe Coupé, an associate professor in the department of linguistics at the University of Hong Kong in China, about the information density of different languages. His work, published this week in Science Advances, suggests very different languages—from Chinese to Japanese to English and French—are all equally efficient at conveying information.

Measles is a dangerous infection that can kill. As many as 100,000 people die from the disease each year. For those who survive infection, the virus leaves a lasting mark—it appears to wipe out the immune system’s memory. News Intern Eva Fredrick joins host Sarah Crespi to talk about a pair of studies that looked at how this happens in children’s immune systems. Read the related studies in Science and Science Immunology. In our second segment this week, Sarah talks with Todd Thompson, of Ohio State University in Columbus, about his effort to find a small black hole in a binary pair with a red giant star. Usually black holes are detected because they are accruing matter and as the matter interacts with the black hole, x-rays are released. Without this flashy signal, black hole detection gets much harder. Astronomers must look for the gravitational influence of the black holes on nearby stars—which is easier to spot when the black hole is massive. Thompson talks with Sarah about a new approach to finding small, noninteracting black holes. This week’s episode was edited by Podigy.

Guided by the recent Every Student Succeeds Act (ESSA), states are scrambling to incorporate nonacademic skills into school measurement systems, raising the question: “What measures should schools use and for which purpose?”

Senior Researcher Elias Walsh looks into helping provide meaningful feedback to "invisible teachers" - those who leave the profession feeling as though they have made no progress with their students.

Principals have almost as much of an impact on student achievement as teachers do. Indeed, we found in a study of school reform in Washington, D.C., that replacing ineffective principals improves student achievement. But how do we distinguish good principals from bad ones?

How do we identify great teachers and help all teachers improve their craft? The best option may be to combine student growth measures, observations of teachers in the classroom, and student surveys.

The lockdown has not ‘killed’ the virus and was never going to. We will have to learn to live with Covid-19, possibly until 2022.

Mathematica’s study helps Louisiana measure its public high schools’ contribution to student outcomes such as high school graduation, college enrollment, and eventual earnings.

This study examines when nonexperiments might substitute for experiments that are done in real-world settings in order to learn what works to affect some socially valued outcome.

In the summer of 2017, the National Quality Forum (NQF) announced the formation of a Scientific Methods Panel (hereafter referred to as “the Panel”) as part of a redesign of its endorsement process.

The panelists discuss the MEAN stack with Ward Bell and Valeri Karpov.

Kaelig Deloumeau-Prigent is a self taught web developer from west France. He has worked for BBC, The Guardian, and The Financial Times in the UK. He has also worked in the US for SalesForce and currently works for Shopify on their Polaris design system. Shopify has multiple design systems, and Polaris is open source. Today the panel is talking about design systems and developer tooling around design systems. 

To begin, Kaelig explains what a design system is. A design system is all of the cultural practices around design and shipping a product. It includes things like the words, colors, spacing grid system, and typography, plus guidance on how to achieve that in code. The panelists discuss what has made design systems so popular. Design systems have been around for a while, but became popular due to the shift to components, which has been accelerated by the popularity of React. The term design system is also misused by a lot of people, for it is much more than having a Sketch file. 

Next, they talk about whether design systems fall under the jurisdiction of a frontend developer or web designers. Kaelig has found that a successful design system involves a little bit of everyone and shouldn’t be isolated to one team. They talk about what the developer workflow looks like in a design system. It begins with thinking of a few common rules, a language, and putting it into code. As you scale, design systems can become quite large and it’s impossible for one person to know everything. You either give into the chaos, or you start a devops practice where people start to think about how we build, release, and the path from designer’s brain to production.

The panelists then talk about how to introduce a design system into a company where there are cultural conflicts. Kaelig shares his experience working with SalesForce and introducing a design system there. They discuss what aspects of a design system that would make people want to use it over what the team is currently doing. Usually teams are thankful for the design system. It’s important to build a system that’s complete, flexible, and extensible so that you can adapt it to your team. A good design system incorporates ‘subatomic’ parts like the grid system, color palette, and typography, referred to as design tokens. Design systems enable people to take just the bits of the design system that are interesting to them and build the components that are missing more easily. 

The conversation turns to the installation and upgrade process of a design system. Upgrading is left up to the customer to do on their own time in most cases, unless it’s one of the big customers. They talk about the role of components in upgrading a design system. Kaelig talks about the possibility of Shopify transitioning to web components. Kaelig shares some of his favorite tools for making a design system and how to get started making one. A lot of design teams start by taking a ton of screen shots and looking at all the inconsistencies.Giving them that visibility is a good thing because it helps get everyone get on the same page. The panelists talk about the role of upper management in developing components and how to prioritize feature development. Kaelig talks about what drives the decision to take a feature out. The two main reasons a feature would be removed is because the company wants to change the way things are done and there’s a different need that has arisen. The show concludes by discussing the possibility of a design system getting bloated over time. Kaelig says that Design systems takes some of the burden off your team, help prevent things from getting bloated, allow you to ship less code.
