How Jayne Mansfield Changed the Design of Tractor-Trailers

Unlike Hedy Lamarr, who actually patented a “secret communication system” during WWII (though the idea wasn't ultimately tweaked and used until the 1906s), Jayne Mansfield didn’t create this product - she just inspired it.

Mansfield was one of the most visible starlets of the 1950s and ‘60s and was constantly compared to Marilyn Monroe for both her platinum blonde hair and her physical, um, assets.

On June 29, 1967, Mansfield, her lawyer, her driver and three of her five children were driving from an appearance in Biloxi, Mississippi, to New Orleans for a TV interview early in the morning. It was just before 2:30 a.m. when her car came up on a tractor-trailer too fast, not seeing it because of anti-mosquito fog clouding the highway. The small car didn’t just rear-end the tractor-trailer; it went completely underneath it, shearing the top of the car off. It also killed the three adult passengers of the car almost instantly. Pictures of the accident site were pretty gruesome; a mass of blonde hair sitting all by itself made people wonder if Jayne had been decapitated or had simply lost her wig. Snopes reports that Mansfield was not decapitated, but she probably was scalped, or something close to it.

Shortly thereafter, the National Highway Traffic Safety Administration made it mandatory for all semi truck trailers to be fitted with under-ride bars, also called DOT bars or Mansfield bars. The steel bar hangs from the main cab and is designed to stop a car before it rolls underneath the trailer (it's the red striped bar hanging down from the semi pictured).

Amazingly, the three children in the backseat survived with minor injuries. One of them went on to follow in her mother’s actress footsteps - you might know her as Law & Order’s Detective Olivia Benson, AKA Mariska Hargitay. She still has a scar from the crash that happened when she was just three years old.

Take a Rare Glimpse Inside the World's Largest Seed Reserve

Since 2008, the remote Arctic island of Spitsbergen has been home to the world’s largest seed storage facility, known as the Svalbard Global Seed Vault.

The 11,000-square-foot facility contains nearly 865,000 seed samples—many of which are crops—and functions as both a reserve in the event of a catastrophe and as a backup for other seed banks around the world. Countries can send samples for preservation and access the reserves as needed (the effort is funded by Norway in conjunction with the organization Crop Trust). The vault was opened for the first time last year in light of the destruction caused by the Syrian War.

Access to the fault is notoriously limited, but AJ+ has a glimpse inside on its YouTube page. It’s a rare look at a place that isn’t known for its looks, but holds some of the planet’s most beautiful and valuable offerings.

This Infographic Explains the Difference Between Perfume and Eau de Toilette

Ever wondered why you can't smell the perfume you dabbed on earlier this morning? Maybe it's because you aren't actually wearing perfume. Instead, you likely applied eau de toilette, cologne, or another type of fragrance.

These sprays contain different concentrations of fragrance oil dissolved in solutions of alcohol and water. Scents with a heavier amount of oil are stronger, they're more expensive, and they also last for longer periods of time. Even the most discerning shopper might not know whether to opt for parfum or eu de parfum when perusing bottles of Chanel No. 5 at the fragrance counter—or even realize there's a difference. 

If you'd prefer to smell like a few roses instead of a field of them, it's handy to know the difference between perfume, eau de parfum, eau de toilette, cologne, and eau fraiche when you're out shopping for a new scent. Lifehacker recently ran this handy infographic by Real Men Real Style, which breaks down the strength of each fragrance along with how long it lasts. Use it as a guide to purchase the perfect product for you.
