The 'Tree of Death' Lives Up to Its Name

At first glance, there’s nothing particularly menacing about the manchineel tree. Until you touch its bark or taste its fruit—which could leave you ill, injured, or even worse—you'd never know how it got its nickname: The Tree of Death.

IFLScience recently took a closer look at Hippomane mancinella, which was first dubbed arbor de la muerte, or “tree of death," by Spanish conquistadors. The tree is native to northern South America, the Galápagos, the Bahamas, the Caribbean, and even Florida, and it’s common to find signs posted on the trees warning passersby against touching it—which can leave chemical burns on your skin—or ingesting its fruit, which is toxic. Of all the toxins in the tree, its most notorious component is the organic compound phorbol, which can be found everywhere from its bark to its sap.

The tree's small, sweet-smelling green fruits, nicknamed “death apples,” are known to strike whomever eats them with diarrhea, seizures, and severe vomiting. At the turn of the 2000s, consultant radiologist Nicola Strickland wrote about her experience mistaking one of these fruits for a crab apple while on vacation in Tobago. After she and her friend each took a small bite, their mouths started to burn and their throats began to swell shut. They also developed a serious pain in their necks as their lymph nodes were infiltrated by the toxins. They survived—but only because they took such tiny bites.

Look Up! Residents of Maine and Michigan Might Catch a Glimpse of the Northern Lights Tonight

The aurora borealis, a celestial show usually reserved for spectators near the arctic circle, could potentially appear over parts of the continental U.S. on the night of February 15. As Newsweek reports, a solar storm is on track to illuminate the skies above Maine and Michigan.

The Northern Lights (and the Southern Lights) are caused by electrons from the sun colliding with gases in the Earth’s atmosphere. The solar particles transfer some of their energy to oxygen and nitrogen molecules on contact, and as these excited molecules settle back to their normal states they release light particles. The results are glowing waves of blue, green, purple, and pink light creating a spectacle for viewers on Earth.

The more solar particles pelt the atmosphere, the more vivid these lights become. Following a moderate solar flare that burst from the sun on Monday, the NOAA Space Weather Prediction Center forecast a solar light show for tonight. While the Northern Lights are most visible from higher latitudes where the planet’s magnetic field is strongest, northern states are occasionally treated to a view. This is because the magnetic North Pole is closer to the U.S. than the geographic North Pole.

This Thursday night into Friday morning is expected to be one of those occasions. To catch a glimpse of the phenomena from your backyard, wait for the sun to go down and look toward the sky. People living in places with little cloud cover and light pollution will have the best chance of spotting it.

The North Face's New Geodesic Dome Tent Will Protect You in 60 mph Wind

The North Face

You can find camping tents designed for easy set-up, large crowds, and sustainability, but when it comes to strength, there’s only so much abuse a foldable structure can take. Now, The North Face is pushing the limits of tent durability with a reimagined design. According to inhabitat, the Geodome 4 relies on its distinctive geodesic shape to survive wind gusts approaching hurricane strength.

Instead of the classic arching tent structure, the Geodome balloons outward like a globe. It owes its unique design to the five main poles and one equator pole that hold it in place. Packed up, the gear weighs just over 24 pounds, making it a practical option for car campers and four-season adventurers. When it’s erected, campers have floor space measuring roughly 7 feet by 7.5 feet, enough to sleep four people, and 6 feet and 9 inches of space from ground to ceiling if they want to stand. Hooks attached to the top create a system for gear storage.

While it works in mild conditions, the tent should really appeal to campers who like to trek through harsher weather. Geodesic domes are formed from interlocking triangles. A triangle’s fixed angles make it one of the strongest shapes in engineering, and when used in domes, triangles lend this strength to the overall structure. In the case of the tent, this means that the dome will maintain its form in winds reaching speeds of 60 mph. Meanwhile, the double-layered, water-resistant exterior keeps campers dry as they wait out the storm.

The Geodome 4 is set to sell for $1635 when it goes on sale in Japan this March. In the meantime, outdoorsy types in the U.S. will just have to wait until the innovative product expands to international markets.
