Repairing the Brain, $20 Hearing Aids, and Turning Parking Lots into Power Plants
The Great News Podcast is brought to you by the Daily Quote (https://greatnewspodcast.com/dailyquote), the podcast designed to kickstart your day in a positive way.
Today, we’re looking at how the empty space in our cities is being turned into a powerhouse of clean energy.
Plus, we’ll explore breakthroughs in repairing the brain, a $20 medical device set to disrupt an entire industry, and why your kitchen pantry might hold the secret to stopping dangerous mosquitoes.
Our lead story today focuses on a global shift to turn "stranded assets", specifically, the massive amounts of asphalt used for parking lots, into solar farms.
In a bold legislative move, South Korea has passed a national law requiring all parking lots with more than 80 spaces to install solar canopies and carports (https://www.reddit.com/r/ThatsGoodNews/comments/1otb66r/new_national_law_will_turn_large_parking_lots/?utm_source=chatgpt.com). This applies to both new and existing lots, aiming to stabilize the local grid while protecting cars from rain and sun.
Meanwhile, in France, the Senate passed a policy requiring similar canopies for large lots, which could generate energy equivalent to 10 nuclear reactors. In the U.S., California’s Senate Bill 49 (https://www.claycord.com/2022/12/07/proposed-legislation-would-turn-parking-lots-into-solar-energy-farms/?utm_source=chatgpt.com)is looking to provide tax incentives for these "miniature power plants," with estimates suggesting that covering just 400 square miles of parking lots could power 6.5 million homes.

Next, we have a double-header of breakthroughs in neurological repair.
Researchers at the University of Helsinki have identified two drug molecules that can restart the brain's natural repair process in Multiple Sclerosis (https://scitechdaily.com/scientists-may-have-found-a-way-to-repair-nerve-damage-in-multiple-sclerosis/) by promoting the regrowth of myelin, the protective nerve coating the disease destroys.
Simultaneously, a study from the University of Zurich and USC found that stem cell-derived brain cells transplanted after a stroke can actually rebuild damaged connections (https://scitechdaily.com/scientists-reverse-stroke-damage-using-stem-cells-in-breakthrough-study/) and restore coordination. These cells didn't just survive; they matured into functioning neurons and triggered a broader healing response across the injured brain.
In the world of affordable healthcare, a group called Founders Inc. has reinvented the hearing (https://www.amanolabs.com/) aid by studying the mechanics of the human ear. While a standard hearing aid can cost an astronomical $4,700,this new version is being brought to market for just $20, potentially making life-changing technology accessible to millions for the first time.
Finally, scientists at Yale have discovered that garlic acts as a powerful birth control for mosquitoes (https://www.futurity.org/garlic-mosquitoes-3334302-2). A natural compound called diallyl disulfide blocks the mating and egg-laying process in species that spread diseases like Zika and yellow fever. Interestingly, it's not the smell that deters them, but a specific taste receptor in their tiny organs that triggers an avoidance behavior.
It's time for the speed round, where we squeeze in even more positivity:

And my favorite quote of the day from the Daily Quote podcast (greatnewspodcast.com/dailyquote) this week is from Walt Whitman (Walt Whitman – “Keep your face always toward the sunshine and shadows will fall behind you.”), who once said,
"Don’t judge each day by the harvest you reap, but by the seeds that you plant"
