When she isn't enjoying an afternoon tea or strolling the grounds of her palace with her corgis, Her Majesty Queen Elizabeth II likes to nurture her side hobby of conserving forests around the globe. The Queen discusses her love of trees with Sir David Attenborough in a new nature documentary called The Queen's Green Planet, airing on ITV in the UK on April 16, the Independent reports.

While walking through the gardens at Buckingham Palace, Sir David and the Queen chat about the royal family's history with trees as well as the legacy she hopes to leave to future generations. With the new initiative, The Queen's Commonwealth Canopy (QCC), she aims to create a global network of forest conservation projects connecting all 53 Commonwealth nations. When we don't see the Queen at her home with Sir David, we follow Prince Harry planting trees in the Caribbean and Prince William visiting Canada's Great Bear Rainforest with his family.

The Queen's insights on big topics like climate change come with amusing tidbits about her personal life. In the documentary, she reveals that her love of trees has had some unexpected consequences: "I’ve been quite difficult to give presents to so … they’ve said, ‘Oh, let’s give her a plant.’”

Leading up to the documentary's premiere later this month, viewers will have a chance to take part in the Queen's initiative. The ITV programs Good Morning Britain and This Morning are inviting people to sign up to receive their own saplings, which will be shipped out for planting in August of this year.

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.

10 "Udderly" Fascinating Facts About Cows

Cows dot fields and pastures across many countries, and cow products are valued and consumed worldwide because their production of milk and meat isn't seasonal, as crops usually are. Cow products can also be preserved for extended use, such as butter, cheese, and smoked or cured meats. And, scientists are still finding new uses for the roughly 80 pounds of manure that a dairy cow produces daily. Chew the cud over these 10 facts about bovines. 

1. COWS ARE KILLERS.

An ABC News report cited a 2012 study, published in Wilderness and Environmental Medicine, which found that cattle cause an average of 22 deaths per year. Sharks, on the other hand, kill about six people per year. It sounds like SyFy should have made Cownado instead.

2. COW TIPPING IS JUST A MYTH.

It might be funny to imagine a sleeping cow falling over with just a gentle shove, but cow tipping isn't that easy. Actually, it's nearly impossible. Cows sleep lying down and are generally wary of approaching humans, so they're never really blissed-out enough to allow a stranger to get close enough to touch them. But the bigger obstacle is their sheer size. Cows are massive—on average 1500 pounds—and balance their weight on all four legs.

3. COWS HAVE COMPLICATED DIGESTIVE SYSTEMS.

Cows' stomachs are made up of four pouches—the reticulum, the rumen, the omasum, and the abomasum—each serving a specific purpose. Cows barely chew their food before it enters the first and largest part of the stomach called the rumen. Once the rumen is full, the cow lies down and the reticulum—which is made of muscle and is connected to the rumen so food and water can easily pass back and forth—pushes the unchewed food back up the esophagus and into the mouth. After re-chewing, or rumination, the food eventually passes through the omasum. The omasum filters out the water and gives the bacteria in the rumen more time to break down the food and take in more nutrients. Finally, the food enters the abomasum, which functions similar to a human stomach.

4. THERE ARE SURROGATE COWS.

Transferring embryos from a genetically superior cow to a merely adequate cow is becoming more common. The procedure—known as embryo transfer (ET)—involves injecting a superior cow with hormones so she produces multiple eggs. Her eggs then need to be fertilized, either naturally or through artificial insemination. When the eggs are fertilized, a vet performs an "embryo flush" to remove them. That generally results in six to seven usable embryos, but can produce as many as 80 or 90. Without hormone treatment, a cow can only produce one embryo.

There are a number of reasons to perform ET—genetically superior cows produce genetically superior eggs. When they're transferred to surrogates, herds gain more powerful and efficient cows, instead of the offspring the surrogates might produce on their own. Embryos are also easily sent overseas to improve the bovine gene pool elsewhere, supplying more (and more efficient) milk-producing cows to countries that lack enough resources to meet demand. (For more on the cow surrogacy process, check out this story from NPR's Abby Wendle.)

5. THE ORIGIN OF THE WORD CATTLE STEMS FROM THE WORD FOR PERSONAL PROPERTY.

According to the Merriam-Webster dictionary, the origin of cattle is chatel, the Anglo-French word for personal property. Chatel comes from the Medieval Latin term capitale.

6. A COW IS TECHNICALLY A FEMALE WHO HAS GIVEN BIRTH TO AT LEAST ONE CALF.

There are specific terms for bovines depending on their age, sex, and purpose. For example, a "bull" is a mature, male bovine used for breeding, while a "steer" is a male that's been castrated and is used for its beef. A "heifer" is a female bovine that has yet to have calves, and a "bred heifer" is a pregnant heifer. There are a number of additional terms that farmers use to describe members of their herd.

7. BULLS CAN'T SEE RED.

A bullfighter could just as easily wave a pink or purple flag to get a bull to charge. The bull isn't angered by the color—all bovines are red/green colorblind. Instead, it's the movement of the cloth that gets it all riled up. The real reason matadors wear red: to hide the bull's blood.

8. COWS WITH NAMES PRODUCE MORE MILK.

If farmers have a good relationship with their cows—meaning they give them names and show enough affection—they can produce more milk than their lonely counterparts. A 2009 study from Newcastle University found that cows who are more comfortable around humans are less stressed when milked. When cows are stressed, they produce cortisol, a hormone that inhibits milk production.  Another plus side of a happy cow-human relationship: farmers are less likely to get injured on the job (see fact #1).

9. INTO THE WOODS USED A REAL COW.

For the 2014 film, director Rob Marshall wanted to use a real, live cow instead of depending on CGI. James Corden, who played the Baker and spent plenty of time with his bovine costar, admitted that things didn't always go smoothly: "You just don't know what it's like when you're doing a scene, and Meryl Streep is giving a phenomenal performance in only the way she can and it's scuppered by just 'Moooooooo,'" he recalled, adding, "That cow was the biggest diva on this set."

10. COWS PRODUCE METHANE, BUT DON'T BLAME THEM FOR GLOBAL WARMING.

Even though cattle produce plenty of methane during digestion, the United States Environmental Protection Agency (EPA) still considers the animals' contribution to global warming our fault, "because humans raise these animals for food and other products." In other words, this is a classic case of "He who smelt it, dealt it."
