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.

Oregon Launches the Country's First State-Wide Refillable Beer Bottle Program

Being a frequent beer drinker doesn't just affect your waistline. It's also not good for the environment—all those cans and bottles add up. But Oregonians soon won't have to feel guilty for the bottles piling up in their trash cans, because the state just launched the first state-wide refillable beer bottle program in the U.S., as NPR and EarthFix report.

Oregon breweries are selling their beer in thicker, heavier beer bottles that customers can return to be cleaned and refilled, just like the milk bottles of yore. Seven craft breweries whose beers are available in stores across the state are currently participating in the refillable bottle program, but the distinct bottles can be used and refilled at any brewery in the state, and the program will likely expand in the coming years.

The bottles, stamped with the word "refillable," are made from recycled glass and can be reused up to 40 times. The design was developed by the Oregon Beverage Recycling Cooperative, and customers can drop them off at any of the group's 21 redemption centers. The organization also runs the state's general container deposit-refund system, so customers can bring them to the same locations as any other recyclables.

The thicker shape allows them to be separated out from other recyclables that get dropped off at bottle deposit sites, ensuring that they get sorted out to be refilled rather than recycled with standard glass bottles.

Oregon passed the first state bottle bill in the nation in 1971 as a way to encourage recycling. In 2018, the state increased the bottle deposit from 5 cents to 10 cents, hoping to increase redemptions. About 73 percent of metal, glass, and plastic recyclables were actually redeemed in 2017, up from 64 percent in 2016.

While refillable beverage containers aren't the norm in the U.S., other countries are far ahead of us. Some provinces in Canada have nearly a 99 percent return rate for their refillable bottles, and the average bottle is reused 15 times. Most beer in Germany is sold in mehrweg, or reusable, bottles, and consumers can return them to any store that sells reusable-bottle beer to get their deposit back.

Though the Oregon program is an environmental boon, the carbon savings won't be as high as they could be. Oregon doesn't yet have a bottle washing facility to process the refillables, so they currently have to be shipped to Montana for washing. Eventually, the program will set up some of these washing facilities in-state, increasing its utility.

You Can Visit Any National Park For Free This Saturday

Looking for something to do this weekend? Within driving distance of one of the country's more than 400 national parks? The timing might work out. On Saturday, September 22, the National Park Service will be celebrating National Public Lands Day by offering free admission to any national park that normally charges an entrance fee.

Established in 1994 by the National Environmental Education Foundation, National Public Lands Day is held annually on the fourth Saturday in September. The day is set aside to recognize and encourage stewardship of green space in individual communities. If you see an opportunity to volunteer that day, you can get a voucher good for admission on a day of your choosing.

Admission to federally owned parks during peak season averages $30 at the 117 locations that require payment for access. Recently, the National Park Service had considered raising the fee to $70 at 17 of the busiest parks. The potential move would help address maintenance and other costs, but it's drawn criticism from conservation groups arguing the locations should remain affordable to visitors. In the end, the NPS decided to raise prices by $5 for one-time entry, or $5 to $10 for an annual pass, though some fees won't rise until 2020.

You can search for parks by state or by activity using the National Park Service Find a Park search engine here. Note that any additional charges for camping or other attractions aren't included in the promotion.

Can't make it this weekend? The parks are open for a fee-free day four times in 2018, down from 10 in 2017. The next date is November 11, in honor of Veterans Day.
