“Health is not valued till sickness comes.” – Thomas Fuller

Most people wait until something’s wrong before they act. But the smarter move? Regular check-ups, early screenings, and paying attention before your body forces you to. Prevention costs less—money, time, and pain—than treatment ever will.

Shark Skin Saves Fuel

An Australian aviation startup is taking inspiration from nature to boost aircraft efficiency. MicroTau has developed an adhesive film modeled after shark skin, using a sandpaper-like texture to reduce drag on airplanes. Sharks are covered in microscopic grooves called riblets, which help them swim with less resistance. When similar grooves are applied to an aircraft’s surface, they work by “smoothing air flow,” ultimately reducing aerodynamic drag.

MicroTau’s ‘Riblet Modification’ can be applied to the wings, fuselage, and tail, improving overall efficiency by up to 4%. “Across the global aviation fleet, this means billions of dollars in fuel saved and millions of tons of CO2 emissions prevented,” says a company statement. The technology has attracted major industry attention—Delta Air Lines has signed an agreement to test the film on its Boeing 767 fleet. The project is part of an “incubator lab” focused on sustainable innovation and includes partners like Airbus, Boeing, JetZero, and electric air taxi developer Joby Aviation.

As the airline industry pushes toward its goal of net zero emissions by 2050, innovations like MicroTau’s are under close watch. While long-term strategies include biofuels and aerodynamic designs inspired by nature—like formations used by migrating geese—MicroTau’s riblet film offers a near-term solution with promising results.

Project Care and Share

Cookies donated to the military – Courtesy of Girl Scouts of Central and Western Massachusetts

Girl Scouts in Massachusetts have donated nearly 14,000 boxes of cookies to U.S. military personnel through their Project Care and Share initiative—a program that allows customers to purchase cookies for donation. On June 6, five of the region’s top cookie sellers helped load the shipment in Westfield. A total of 13,989 boxes are now en route to Barnes Air National Guard and the USO for distribution to active service members. “Every scout, every person, can make an impact in their own way,” said Shaylynne Rappazini, a Girl Scout Senior and the program’s top cookie seller.

Selling cookies has long been a Girl Scout tradition, promoting skills like goal setting, entrepreneurship, and community engagement. Project Care and Share takes that tradition a step further by offering scouts a chance to serve others directly. This year, 1,771 Girl Scouts from Central and Western Massachusetts participated in the donation effort, highlighting the program’s core values of leadership, teamwork, and generosity.

“The Girl Scout Cookie Program is about so much more than cookies. Through Project Care and Share, girls learn how to give back,” said Theresa Lynn, CEO of the Girl Scouts of Central and Western Massachusetts. “It’s a gesture of gratitude led by the girls themselves.”

Returned After 80 Years


Joseph L. Gray’s dog tag from WWII – SWNS

The dog tag of World War II soldier Joseph L. Gray has been returned to his family—80 years after his death in a tragic crash. Gray was one of 31 U.S. servicemen killed in April 1945 when their B-17 Flying Fortress went down on the Isle of Man. In 2010, a metal detectorist discovered his dog tags and turned them over to the Manx Aviation and Military Museum, where they remained for more than a decade.

Earlier this year, Donald Madar—a great nephew of another serviceman who died in the same crash—recognized Gray’s name while visiting the museum. Madar, who runs a Facebook group about the accident, recalled that a member of Gray’s family had contacted him during the pandemic. That memory sparked a chain of events that led to the return of the tag. Madar eventually located Gray’s great niece, Bridgette Daily, and called the tag a “prized possession.” “It was a wonderful moment handing the tag over,” he told SWNS. “I could see the emotion rush into her. Her eyes began to tear up. I could tell it was so important for her family that they took possession of a piece of their history.”

Madar, from Pennsylvania, has spent the past 20 years researching the crash that killed his relative, also named Donald Madar. In April, he traveled to the Isle of Man for the 80th anniversary and received Gray’s tag and a handwritten note from historian Ivor Ramsden. Remembering a Facebook post from Clare Quinn—another of Gray’s great nieces—he coordinated with her sister to return the tag. Last month, Madar drove 40 minutes to meet Bridgette at a U.S. restaurant, where he handed over the tag and note. “It was great to get to know him through her stories,” he said.

I rise without legs,
I blaze without flame,
I never speak,
Yet all know my name.
I chase away shadows,
But flee when it’s night—
What am I,
That brings the world light? — sun! Debbie Ettinger got this correct!
