Blind spots in cars are a significant safety issue. You might be at a stop and not notice a pedestrian about to cross because they're hidden by your car's frame. But a 14-year-old inventor has devised an ingenious way to eliminate these blind spots.

Alaina Gassler, a brilliant young mind from West Grove, Pennsylvania, showcased her idea at the Broadcom MASTERS competition for middle schoolers, organized by the Society for Science and the Public.

She built a relatively simple system out of a webcam, projector, and 3D-printed materials that projects the view from outside your vehicle onto the blind spots of your car. She titled her project "Improving Automobile Safety by Removing Blind Spots."

The whole thing basically gives you x-ray vision, and Gassler hopes that it will help drivers be safer on the road by giving them a more complete view of their surroundings.

Gassler's idea earned her first place in the nationwide competition, along with the $25,000 Samueli Foundation Prize for overall STEM excellence.

In an email to Mashable, Gassler explained how her innovative system works.

"She mounted the webcam outside the passenger side A-pillar on a car and then displayed the live video on the inside pillar from a projector attached to the sunroof above the driver's seat. She even had to print a special part to help focus the projector at such close range. She then faced issues with projecting the image on the interior frame. So she resurfaced it with retro reflective fabric."

She went on to explain in the email that the material "only reflects light back to the light source, which is the projector in this case. Since the driver's eyes are next to the projector, the driver can see a crisp, clear image, and the passengers only see a black piece of fabric.”

She replaced the material when she noticed that anyone not sitting in the driver's seat would get a headache from the distorted image. "During testing when I sat in the passenger seat of the car and the moving light from the projector gave me a headache," she said.

Mom honors her loss by helping 3 children get bionic arms for Christmas

Think bionic arms are just the stuff of superhero movies? Think again. Thanks to an incredible blend of cutting-edge technology and the power of community, three children in the UK were given their new "life-changing" Hero Arms on December 12—just in time for Christmas. For Zoey Hampton-Pigeon (8), Finley Jarvis (11), and Ettie Baker (8), their new “Hero Arms” aren’t just cool gadgets—they’re life-changing miracles.

Their story is made possible by the Big Hero 3 campaign, a fundraising initiative started by mother Sarah Lockey, who launched the campaign to help families of children with missing limbs fundraise for bionic arms. This grassroots movement raised a total of £60,000 for the three children—£40,000 from the Open Bionics Foundation, The Worshipful Company of Glovers, Foresight Group, and an anonymous donor and an additional £20,000 raised collectively by the three families themselves.

This throwback psychology test claims to reveal your hidden dark side

There are countless personality quizzes and psychology tests claiming to reveal truths about yourself. The Szondi test, for example, shows how our understanding of mental health has evolved. Developed by Hungarian psychiatrist Léopold Szondi in 1935, the Szondi test aimed to uncover suppressed traits hidden in a person's subconscious.

The test involved looking at a series of 48 photos of people with distinct expressions on their faces. The patient was supposed to pick the friendliest faces and the unfriendliest, the idea being that a person identifies with "like" people and that their choices from the pictures would represent traits of themselves. Despite lacking scientific value, a shortened version of this test recently went viral, capturing people's interest.

Drones are firing seed pods to plant forests — and it’s actually working

Technology is the single greatest contributor to climate change but it may also soon be used to offset the damage we’ve done to our planet since the Industrial Age began. In September 2018, a project in Myanmar used drones to fire “seed missiles” into remote areas of the country where trees were not growing. Less than a year later, thousands of those seed missiles have sprouted into 20-inch mangrove saplings that could literally be a case study in how technology can be used to innovate our way out of the climate change crisis.

“We now have a case confirmed of what species we can plant and in what conditions,” Irina Fedorenko, co-founder of Biocarbon Engineering, told Fast Company. “We are now ready to scale up our planting and replicate this success.”

The Himalayas on a clear day.

The towering Himalayas may seem unshakable, but deep beneath them, the Earth is shifting in ways scientists never expected.

The world’s most dangerous tectonic secret might lie under the Himalayas

The Himalayas, one of the most awe-inspiring mountain ranges on Earth, have long captured the imaginations of adventurers and scientists alike. Towering above the clouds, these colossal peaks hold not only breathtaking beauty but also crucial geological secrets. Recent research suggests something astonishing: the Indian tectonic plate—the very foundation of the Himalayas—may be splitting in two deep beneath the surface.

For millions of years, the Indian Plate has been pushing northward, colliding with the Eurasian Plate and giving rise to the Himalayas. But new findings from Stanford University geologist Simon L. Klemperer and his team indicate that this seemingly solid landmass is undergoing a dramatic transformation, one that could have significant implications for earthquakes and mountain stability in the region.

Sea otters have come to the rescue on the coast of one California town.

Otters are wiping out all the crabs. Scientists say it’s saving the coast.

It is an established scientific fact that otters are adorable. They hold hands with fellow otters as they drift atop the water and use rocks to playfully crack open clams. Hermione's patronus is a sea otter! They're also voracious eaters, consuming about a quarter of their body weight daily. That last bit led them to become ecological superheroes in one California coastal town.

At Elkhorn Slough in California, a thriving population of southern sea otters has taken on an unlikely role: invasive species exterminators. According to USA Today, the otters’ voracious appetite for European green crabs, one of the West Coast’s most destructive invasive species, has nearly wiped the crabs out in the estuary. This has helped revive a delicate ecosystem that had been struggling for decades.

European green crabs, originally from Europe as you might have guessed, arrived on the West Coast in the 1980s and quickly became a menace. Though small—just four inches across—they wreak havoc on coastal ecosystems by devouring seagrass, baby crabs, and salmon while competing with native species. They’ve also caused significant damage to multimillion-dollar shellfish industries for Dungeness and king crabs.
