Billions of years ago, Mars probably hosted many water features: streams, rivers, gullies, etc. But until recently, water detected on the Red Planet was either locked up in ice or flitting about as a gas in the atmosphere. Now, researchers analyzing radar data from the Mars Express mission have found evidence for an enormous salty lake under the southern polar ice cap of Mars. Daniel Clery joins host Sarah Crespi to discuss how the water was found and how it can still be liquid—despite temperatures and pressures typically inhospitable to water in its liquid form. Read the research. Sarah also talks with science journalist Katherine Kornei about her story on changing athletic performance after gender transition. The feature profiles researcher Joanna Harper on the work she has done to understand the impacts of hormone replacement therapy and testosterone levels in transgender women involved in running and other sports. It turns out within a year of beginning hormone replacement therapy, transgender women plateau at their new performance level and stay in a similar rank with respect to the top performers in the sport. Her work has influenced sports oversight bodies like the International Olympic Committee. In this month’s book segment, Jen Golbeck interviews Andrew Lawler about his book The Secret Token: Myth, Obsession, and the Search for the Lost Colony of Roanoke. Next month’s book will be The Book of Why: The New Science of Cause and Effect by Judea Pearl and Dana Mackenzie.

Episode Summary

Special guest Chris DeMars is from Detroit, MI. Currently, he works for Tuft and Needle and is an international speaker, Google developer expert, Microsoft mvp, and web accessibility specialist. He comes from a varied work background, including truck driving and other non-tech jobs.

Today the panel discusses web accessibility for people with disabilities. According to a study done by WebAIM, 97.8% of homepages tested had detectable WCAG 2 failures. The panel discusses why web accessibility is doing so poorly. Chris talks about some of the biggest mistakes he sees and some very simple fixes to make sites more accessible. Chris talks about the importance of manual testing on screen readers and emphasizes that it is important to cover the screen to make sure that it really works with a screen reader. Chris talks about some of the resources available for those who wish to increase accessibility on their sites.

The team discusses tactics for prioritizing accessibility and if there is a moral obligation to make sites accessible to those with disabilities. Chris talks about his experience making accessibility a priority for one of the companies he worked for in the past. They discuss the futue of legal ramifications for sites that do not incorporate accessibility, and what responsibility falls on the shoulders of people who regularly use assistive devices to notify companies of issues. They finish the show with resources available to people who want to learn more.
