This Self-Cloning Tick is Terrorizing More States

Few arachnids are as demonized in the summer months as ticks, the parasitic little nuisances that can spread disease in humans and pets. That's not likely to change now that there's a exotic new species that can not only self-replicate, but is also poised to attack animals like a colony of swarming fire ants.

This super-tick is Haemaphysalis longicornis, or the longhorned tick, native to East Asia and imported to the U.S. by unknown means. The first North American sighting took place in August 2017 in New Jersey when a farmer walked into a county health office covered in nearly 1000 ticks after shearing a pet sheep that had been infested. The insect was then spotted in Virginia, West Virginia, and Arkansas, with caution advised in Maryland. As of this week, it’s now a confirmed resident of North Carolina, The Charlotte Observer reports.

H. longicornis invites more dread than a conventional tick for several reasons. It can “clone” itself, with females laying up to 2000 genetically identical eggs without any assistance from a male, a process called parthenogenesis. Reproduction is faster, with offspring appearing in just six months compared to two years for common deer ticks. It’s also an aggressive biter, nibbling on any animal flesh it can latch on to, and is able to transfer a host of diseases in the process—some of them fatal. In addition to Lyme, longhorned ticks can transmit the flu-like ehrlichiosis bacteria and the rare Powassan virus, which can cause brain inflammation.

The news isn’t much better for livestock. Given enough opportunity, the ticks can siphon enough blood from an animal to kill it, a process known as exsanguination. The attack can become so concentrated that pets have been spotted with ticks hanging from them like bunches of grapes.

New Jersey officials have confirmed the tick has survived the winter by burrowing underground, a somewhat ominous sign that the invasive species might be durable enough to become a widespread problem. Experts recommend taking all the regular precautions, including wearing long pants when outdoors, using repellent, and examining yourself and your pets for ticks. While the longhorned tick hadn’t yet displayed a taste for human flesh, it’s better to be safe than sorry. As for the sheep: following a chemical treatment, she made a full recovery.

Are You Eco-Conscious? You Could Win a Trip to the Dominican Republic

Do you love lounging on the beach but also want to take action to save the planet? You'll be able to do both if you're chosen to serve as a "sustainability advisor" for a luxury resort in the Dominican Republic, Lonely Planet reports.

The worldwide contest is sponsored by Eden Roc at Cap Cana in Punta Cana. The winner and one friend will receive a five-night stay at the Relais & Châteaux hotel, where they'll partake in specially curated activities like a food-sourcing trip with the hotel's chef. (One caveat, though: Airfare isn't included.)

You don't need a degree in conservation to enter, but you will need an Instagram account. Give the resort's Instagram page (@edenroccapcana) a follow and post a photo of you carrying out an eco-friendly activity on your own page. Be sure to tag the resort and use the official hashtag, #EcoEdenRoc.

The only requirement is that the winner meet with hotel staff at the end of his or her trip to suggest some steps that the hotel can take to reduce its environmental impact. The hotel has already banned plastic straws and reduced its usage of plastic bottles, and the sole mode of transport used on site is the electric golf cart.

Beyond the resort, though, the Dominican Republic struggles with deforestation and soil erosion, and the nation scored poorly on the 2018 Environmental Performance Index for the agricultural category.

Entries to the contest will be accepted until August 31, and you can read the full terms and conditions here.

How a Hairdresser Found a Way to Fight Oil Spills With Hair Clippings

The Exxon Valdez oil tanker made global news in 1989 when it dumped millions of gallons of crude oil into the waters off Alaska's coast. As experts were figuring out the best ways to handle the ecological disaster, a hairdresser from Alabama named Phil McCroy was tinkering with ideas of his own. His solution, a stocking stuffed with hair clippings, was an early version of a clean-up method that's used at real oil spill sites today, according to Vox.

Hair booms are sock-like tubes stuffed with recycled hair, fur, and wool clippings. Hair naturally soaks up oil; most of the time it's sebum, an oil secreted from our sebaceous glands, but it will attract crude oil as well. When hair booms are dragged through waters slicked with oil, they sop up all of that pollution in a way that's gentle on the environment.

The same properties that make hair a great clean-up tool at spills are also what make animals vulnerable. Marine life that depends on clean fur to stay warm can die if their coats are stained with oil that's hard to wash off. Footage of an otter covered in oil was actually what inspired Phil McCroy to come up with his hair-based invention.
