Doctors, Engineers, and a Wedding Dress Maker Design a Better Ebola-Proof Suit

Chocolate sauce, it turns out, is an important weapon in the ongoing fight against infectious diseases

To properly fight Ebola, you have to dress the part.


To date that’s meant a full body, multi-part hazmat suit, complete with goggles, gloves, and boots, all designed to provide maximum protection from exposure to the infectious disease. They are quite literally an aid worker’s first line of defense when dealing with dangerous diseases. They are also, it turns out, long overdue for an upgrade.

When it comes to hazmat suits, the challenge is often a matter of time. Suiting up properly can take as long as twenty minutes, says Wired. Once on, the suits’ layered design can render them intensely uncomfortable to wear, with workers usually lasting around 45 minutes before needing to start the undressing process, according to PBS Newshour. To complicate matters further, even when worn correctly, a standard hazmat suit doesn’t necessarily provide a fully seamless barrier against infection, since the helmet is an entirely separate unit from the rest of the protective clothing.

To address these challenges, employees from the United States Agency for International Development (USAID) began reaching out and asking for volunteers to help with a new challenge: Build a better Ebola suit.

Accepting the call were doctors, researchers, students, and even a wedding dress designer. Over sixty people in all converged on the campus of Johns Hopkins University this past winter for a JHU-sponsored “Grand Challenge” to assess realistic ways of improving upon the suit’s design. Constrained by real-world considerations (for example, changing the suit’s material to something other than the currently-used Tyvek fabric would be too expensive), the team began exploring the hazmat suit’s fundamental design flaws. Things like: accessibility, ventilation, and contamination-points.

As Johns Hopkins University Center for Bioengineering Innovation and Design’s Youseph Yazdi explained to PBS' Mary Jo Brooks, one of the team’s secret weapons was chocolate sauce: "Because you want the see if you can protect yourself from contamination. So you rub the stuff all over yourself and then try to take off the suit and then see if any of it got on your skin. That’s — it’s a poor man’s simulation."

What they came up with is a prototype that’s lighter, simpler, and easier to put on.

The suit design was selected for funding by USAID along with fourteen others from out of fifteen hundred other ideas submitted by teams and tinkerers around the world. As PBS reports, the prototype is currently undergoing further testing and design refinement before it’s scheduled for manufacturing this summer.

This isn’t the first instance of non-professionals revamping an existing tool to better combat highly infectious diseases. Earlier this year a team of volunteers, partnering with both Google engineers and Doctors Without Borders, helped create a specially designed “Ebola-proof” computer tablet to be used in disease hot-zones without fear of contamination.

Sin City is doing something good for its less fortunate citizens as well as those who've broken the law this month. The city of Las Vegas, Nevada will drop any parking ticket fines for those who make a donation to a local food bank.

A parking ticket can cost up to $100 in Las Vegas but the whole thing can be forgiven by bringing in non-perishable food items of equal or greater value to the Parking Services Offices at 500 S. Main Street through December 16.

The program is designed to help the less fortunate during the holidays.

For more than 20 years. Sen. Susan Collins (R-ME) has served the citizens of Maine in the U.S. Senate. For most of that time, she has enjoyed a hard-fought reputation as a moderate Republican who methodically builds bridges and consensus in an era of political polarization. To millions of political observers, she exemplified the best of post-partisan leadership, finding a "third way" through the static of ideological tribalism.

However, all of that has changed since the election of Donald Trump in 2016. Voters in Maine, particularly those who lean left, have run out of patience with Collins and her seeming refusal to stand up to Trump. That frustration peaked with the nomination of Brett Kavanaugh to the Supreme Court.

The U.K. is trying to reach its goal of net-zero emissions by 2050, but aviation may become the biggest source of greenhouse gas emissions in the U.K. by that same year. A new study commissioned by the Committee on Climate Change (CCC) and conducted at the Imperial College London says that in order for the U.K. to reach its target, aviation can only see a 25% increase, and they've got a very specific recommendation on how to fix it: Curb frequent flyer programs.

Currently, air travel accounts for 2% of global greenhouse gas emissions, however that number is projected to increase for several reasons. There's a growing demand for air travel, yet it's harder to decarbonize aviation. Electric cars are becoming more common. Electric planes, not so much. If things keep on going the way they are, flights in the U.K. should increase by 50%.

Nearly every airline in the world has a frequent flyer program. The programs offer perks, including free flights, if customers get a certain amount of points. According to the study, 70% of all flights from the U.K. are taken by 15% of the population, with many people taking additional (and arguably unnecessary) flights to "maintain their privileged traveler status."
