When it comes to U.S. middle school science and engineering, girls rule. Girls took the top five prizes at the 2019 Broadcom MASTERS, a competition for middle school students across the country.
The winners were announced last month. The winners were honored for their STEM successes, as well as for showing skills in critical thinking, communication, creativity and team-work. In first place was 14-year-old Alaina Gassler of West Grove, Pennsylvania. She designed a system to make driving safer by reducing blind spots — the areas that drivers cannot see outside their vehicle. Gassler developed the technology while in eighth grade. “She, along with the entire Class of 2019, are already leaders in their fields of science, technology, engineering and mathematics (STEM),” said Paula Golden, president of the Broadcom Foundation. “These young creators give every one of us hope for the future.”
The Broadcom MASTERS competition is a project of the Society for Science & the Public. It was set up to motivate young people to attend college and pursue careers in STEM fields. It was open to students in grades 6, 7 and 8 across the country.
The top prize winner, Alaina Gassler, says she got the idea for her project after seeing her mother struggle with blind spots in her family’s car. Blind spots lead to many accidents — about 840,000 accidents a year nationwide.
Gassler’s system helps drivers see “through” the A-frame pillar (A柱) — the part of the vehicle, in the front, that joins the top and front window. The A-frame pillar is important for safety, and cannot be removed. Gassler used a camera to help drivers look “through” the structure to see what is blocked. The camera sends video to a device that shows images on the other side of the pillar. The driver then can “see” what’s in the blind spot.
The young inventor won a $25,000 prize for her invention. She told Popular Mechanics she can make improvements on her device with that money. Gassler said she wants to improve the picture — making it easy to see in any weather, or any time of the day. She also told the magazine she hopes to sell her idea.

Does your ideal vacation include going skiing across frozen ice, spying the northern lights, and playing in the snow? Then you’ll want to skate straight to these winter spots.
Fairbanks, Alaska
Alaska is a good choice for a great winter getaway. For winter fun, head to Fairbanks, where you can stay at a new cottage with glass-ceiling domes for aurora (极光) viewing in comfort and then head out ice fishing and snowmobiling. Want even more adventure? Consider a guided adventure that combines northern lights, cross-country skiing, and dog mushing.
Kirkenes, Norway
The Kirkenes Snow hotel here welcomes visitors to its ice-sculpted rooms. Besides, you can jump on a sled (雪橇) pulled by dogs or bring your appetite for a King Crab Safari. First, you’ll be on a sled pulled by a snowmobile across the icy sea. Then crab fishermen drill into the ice to create a hole to pull up the large crabs. Another quick sled trip and you’ve reached a cozy cottage where crab claws as long as your forearm are served up minutes after being pulled from the cold waters, tasting of salt water. A rich reward for braving the cold.
St. Moritz, Switzerland
Skiing down the Alps is obviously a highlight here, but did you know that night skiing in this Swiss town is some of the best in the world? Picture it: Clear sky, full moon, inky quiet, and a sky full of stars. If you need energy for skiing, you can always refuel with pizza from the wood-fired oven at Murtèl middle station. You can keep skiing until the last cable car at 1:40 a. m. Then, check into your room at the Carlton Hotel, where there are a series of daylight activities.
Quebec City, Canada
In the summer months, Quebec City is an excellent destination thanks to its French features and historic old port. But in the winter, don’t miss the Winter Carnival, the Carnaval de Quebec, the largest winter carnival in the world. During 17 days the Carnival offers more than 200 activities and welcomes nearly 500,000 people (upcoming dates are January 26 to February 11, 2018, and February 1 to 17, 2019).
