These Drones Can Plant 100,000 Trees in One Day

Billions of trees are felled each year, according to the Rainforest Action Network, and planting a tree requires more time and effort than cutting one down. That makes keeping up with deforestation rates challenging for conservationists. The minds behind one tech startup think they can speed up global tree-planting efforts by taking the burden off humans and placing it on drones.

BioCarbon Engineering has assembled a fleet of drones that can plant thousands of trees a day, as Fast Company reports. The company will soon focus its efforts on Myanmar’s Irrawaddy River delta, an area that’s seen rapid loss of its mangrove trees due to aquaculture, agriculture, and logging. Estimates place the amount of regional mangroves destroyed in the past 30 years between 75 and 83 percent. Starting in September, BioCarbon will partner with Worldview International Foundation to aid restoration efforts started by human hands.

Spreading seeds from aircraft (like helicopters) is not a new strategy. These methods are valued for their speed, but chances of tree survival are hurt in the process. To come up with an efficient way of planting that doesn’t damage seeds, BioCarbon had to get innovative.

After the company maps a plot of land from above and analyzes the best spots for planting, their drones fly low to the ground and fire nutrient-packed seed pods into the soil. This way, more seeds end up in places where they’ll thrive rather than on rocks or in streams where they’ll go to waste.

With one human pilot for every six drones, the company is able to get 100,000 pods in the ground a day. Even in places with regulations restricting pilots to one drone at a time, the vehicles are 10 times faster and half as expensive as human labor. Worldview International Foundation, which has worked with the Irrawaddy delta community to plant 750 hectares of trees so far, hopes to expand that area by 250 hectares with help from BioCarbon Engineering. The team also plans to continue employing locals to assemble seed pods and cultivate saplings.

Pod Search, a Search Engine for Podcasts, Can Help You Find Your Next Binge-Listen

Having too many options definitely seems like the best problem to have when it comes to picking your next top podcast obsession, but that doesn’t make it any less overwhelming. To streamline the hunt, try Pod Search—a website and mobile app that has all the information you need in order to choose a winner.

As Lifehacker reports, the user-friendly site is organized in several different ways, depending on how you’d like to operate your search. You can browse its list of about 30 categories, which range from “Storytelling” to “Crime & Law,” and each has a set of subcategories so you can get even more specific. If you trust the opinions of the general public, you can choose an already-popular podcast from the “Top Podcasts” tab. Or, if you like to be the first to recommend the next big thing to your friends, you can pick a program from the list of new podcasts.

Pod Search also has a handy tool called MyPodSearch which will pretty much do all the work of choosing the perfect podcast for you. All you have to do is check whichever categories interest you and add any additional keywords you’d like (which is optional), and MyPodSearch will deliver a list of podcasts personalized for your tastes. This is great for people who have wide-ranging interests, a proclivity for indecision, or both.

Each podcast has its own landing page with a description, audio samples, places you can listen, website and social media links for the podcast, and a list of other podcasts from the same producers. You can also create an account and bookmark podcasts for the future—so, hypothetically, you could have MyPodSearch create a personalized list for you, bookmark them all, and then have a binge-listening itinerary that’ll last you until next year.

Playing Jeopardy! While You Drive Is the Best Way to Deal With Your Boring Commute

More than 55 years after making its television debut, Jeopardy! continues to hold a prominent place in popular culture. Last spring, James Holzhauer went on a 32-game winning streak, coming just $58,484 short of beating all-time champion (and Mental Floss contributor) Ken Jennings' $2.52 million winnings.

If only Holzhauer had an app to practice with during the drive to the studio. Now, thanks to Drivetime, future contestants and general trivia enthusiasts have that opportunity. The service just launched a Jeopardy! add-on that allows players to answer questions from the first 35 seasons of the show using Drivetime’s voice-based, hands-free interface. A new show will be available to Drivetime users daily. If they subscribe for $9.99 monthly, they can choose any show from past seasons. Questions are read by host Alex Trebek in both archival and recently taped audio.

The game offers one tweak for civilians: As each clue is read, the app offers three possible responses, turning it into a multiple-choice quiz. Money is still accrued and you can still wager on Final Jeopardy to walk away with a victory.
