This Waterless Toilet Made of Mushrooms Could Be Key for Refugee Needs

In many parts of the world, toilets remain out of reach. An estimated one in three people in the world don't have access to a toilet, and one in nine people don't have access to safe water (in large part because of that lack of toilets). A group of students from the University of British Columbia have come up with a new way to give people without plumbing clean, safe places to do their business, and according to Co.Design the key is mushrooms.

The MYCOmmunity Toilet, which just won the 2018 Biodesign Challenge, is a portable toilet kit designed for refugee camps that uses a mycelium (a mushroom product) tank to eventually turn human waste into compost. Everything needed to set up the toilet is packed into one kit, which users can set up into a small, sit-down toilet with a traditional seat and a tank for waste. The appliance is designed to fit into a refugee tent and serve a family of six for up to a month.

The toilet separates solid and liquid waste for separate treatment. Enzyme capsules can be used to neutralize the smell of urine and start the decomposition, and poop can be covered in sawdust or other material to tamp down odors and rev up the composting process. After the month is up and the tank is full, the whole thing can be buried, and the mushroom spores will speed along the process of turning it into compost. The kit comes with seeds that can be planted on top of the buried toilet, turning the waste into new growth. (Biosolids have been used to fertilize crops for thousands of years.)

The University of British Columbia students—led by Joseph Dahmen, an assistant professor in the architecture school, and Steven Hallam, a professor in the department of microbiology and immunology—competed against 20 other design teams at the 2018 Biodesign Summit at the Museum of Modern Art in New York City in June, taking home first prize. They hope to further refine the prototype in the future, and according to Co.Design, test it out at local music festivals, which, with their outdoor venues and high volume of drunk pee-ers, are the perfect venue to stress test waterless toilet technology.

Denver's Temperature Dropped a Record 64 Degrees In 24 Hours

One sure sign summer is over: On Wednesday, residents of Denver, Colorado were experiencing a comfortable 82-degree day. Just before midnight, the temperature dropped to 29 degrees. Between Wednesday and Thursday afternoon, the Denver airport recorded a differential of 79 degrees down to 24 degrees. At one point on Wednesday, a staggering 45-degree drop was seen in the span of just three hours.

All told, a one-day span saw a 64-degree change in temperature, from a high of 83 to a low of 19, a record for the state in the month of October and just two degrees shy of matching Denver’s all-time record drop of 66 degrees on January 25, 1872. On that date, the temperature plummeted from 46 degrees to -20 degrees.

Back to 2019: Citizens tried their best to cope with the jarring transition in their environment, to mixed success. On Wednesday, the city’s Washington Park was full of joggers and shorts-wearing outdoor enthusiasts. Thursday, only the most devoted runners were out, bundled up against the frigid weather.

The cold snap also brought with it some freezing drizzle which prompted several vehicular accidents, including 200 reported during Thursday's morning commute. It’s expected to warm up some in the coming days, but residents shouldn't get too comfortable: Melting ice could lead to potholes.

Invasive Snakehead Fish That Can Breathe on Land Is Roaming Georgia

A fish recently found in Georgia has wildlife officials stirred up. In fact, they’re advising anyone who sees a northern snakehead to kill it on sight.

That death sentence might sound extreme, but there’s good reason for it. The northern snakehead, which can survive for brief periods on land and breathe air, is an invasive species in North America. With one specimen found in a privately owned pond in Gwinnett County, the state wants to take swift action to make certain the fish, which is native to East Asia, doesn’t continue to spread. Non-native species can upset local ecosystems by competing with native species for food and habitat.

The Georgia Department of Natural Resources’ Wildlife Resources Division is advising people who encounter the snakehead—a long, splotchy-brown fish that can reach 3 feet in length—to kill it and freeze it, then report the catch to the agency's fisheries office.

Wildlife authorities believe snakeheads wind up in non-native areas as a result of the aquarium trade or food industry. A snakehead was recently caught in southwestern Pennsylvania. The species has been spotted in 14 states.
