“It is at these times you realize the blessing of a good, thick skirt,” said Mary Kingsley after she crashed into a cleverly concealed leopard pit lined with twelve-inch ivory spikes.
The year was 1895, the place Equatorial West Africa, and the spunky lady saved, thanks to her observance to the dress code of the day, was a young Englishwoman collecting species of fish and beetles for the British Museum.
Mary Kingsley was the daughter of a physician who spent most of his time traveling. Although she received no formal education (reserved for her brother Charles), Mary learned to read, becoming fascinated with subjects such as science, exploration and piracy.
At one point she was granted permission to teach herself German, but only after she could iron a shirt properly. Mary learned chemistry, experimented with gunpowder and electricity, and became engrossed by the intricacies of plumbing. After years of caring for her invalid mother, in 1892 both her parents died. With the small inheritance left to her came the fulfillment of a dream: to explore West Africa.
When Mary crashed into the leopard pit, she was traveling in what was then the French Congo, getting to know the Fangs, reportedly a tribe of cannibals. Traveling by canoe, she was once marooned in a crocodile-infested lagoon. When one tried to climb aboard, she was there with a paddle, ready to “fetch him a clip on the snout.”
After two trips, she wrote a book called Travels in West Africa. She became a sought-after lecturer and celebrity. In public appearances she was both funny and serious, peppering her narrative with jokes, often at her own expense, but also being critical of the way the British had steamrolled into the African continent, with little regard for its ancient cultures.
In 1900 she sailed to Africa for the third time, responding to an urgent call for nurses in South Africa, where war was underway. Assigned to a hospital where hundreds of soldiers were dying from a raging epidemic, she became ill herself, and died two months later. She was buried at sea with military honor.
In her book, she remembers: “Indeed, much as I have enjoyed life in Africa, I do not think I ever enjoyed it to the full as I did when dropping down the Rembwe… Ah me! Give me a West African river and a canoe for sheer pleasure.”
Rave reviews for Roxie Munro's book Market Maze:
"A great way to introduce kids to their foods' origins and to prepare them for a greenmarket visit of their own." Kirkus (Starred review!) excerpt.
"From a parent’s or teacher’s point of view, here’s a good way for kids to gain the visual discrimination skills needed for reading, while they learn about the sources of food at their local farmers’ markets. For kids, though, the combination of mazes and hidden objects is just plain fun. It’s a winning combination." Booklist review excerpt.

Are you tougher than a tardigrade? I don’t think so.
These typically water-dwelling animals may be microscopic in size (barely half of a millimeter when fully grown!), but boy are they fierce. Sometimes called “water bears,” they’re anything but cuddly. Each of their eight legs is decked out with wicked claws. Some tardigrades have full body armor. Most have specialized "sucker" mouths to pierce the cells of plants and animals and suck out their nutrients, while others prefer to consume their tiny prey whole… and that prey might even be another tardigrade!
Aside from ending up as someone else’s dinner, though, tardigrades are practically indestructible. They can survive in just about any conditions and take on just about anything life has in store for them. Starvation? No worries there: Tardigrades can go without food for at least 10 years. What about water, you say? No problem. They’ll just suspend their life activities and wait until the drought is over. They can survive at pressures more than six times that of the deepest ocean trenches. And, you’d die from radiation poisoning long before a tardigrade would even notice. Scientists have even tried shooting them into outer space… and the tardigrades survived.
Because of their ability to live practically anywhere, these little guys are practically everywhere. Tardigrades can be found on top of Mount Everest and in boiling hot springs, in desert dunes and rainforest canopies, in freshwater lakes and salty oceans, on your roof, outside your front door… maybe even in your bed or on your dinner plate! There are billions and billions of tardigrades… and they’re always making more!
Fortunately, there’s no need to worry—tardigrades are completely harmless to humans. In fact, tardigrades may actually end up being our best friends someday. Because they can do so many things that other Earthly animals can’t, scientists are studying tardigrades to try to find solutions to all kinds of problems. Want to dry something out to preserve it, then rehydrate it later? Study how tardigrades do it. Wish we could safely reanimate something that has been frozen? Learn from the tardigrades. Need to protect cells from being damaged by radiation? Figure out why tardigrade cells can withstand it.
Who knows? Someday the tough tardigrades might teach us all kinds of handy tricks!

Question: If your favorite snack was just out of reach, what would you do?
That’s what Preston Foerder, who studies animal behavior, asked Kandula, a male Asian elephant at the Smithsonian National Zoological Park in Washington, D.C. Scientists have always thought that using a tool to solve a problem was a sign of higher intelligence. They also thought that only humans were tool users. But then Jane Goodall discovered chimps using sticks to fish termites out of a hole, and ravens were observed making hooks to nab a treat. People who’ve worked with elephants have long known that they are highly intelligent, but no one ever tested an elephant’s ability to use a tool to solve a problem.
To set up the experiment, Preston skewered Kandula’s favorite fruits on a branch and suspended it well out of trunk reach. Then he scattered potential tools such as long bamboo sticks and a heavy-duty plastic cube around the yard.
At first Kandula just stared at the fruit longingly. Occasionally he picked up a stick, but only played with it. On the seventh trial, Kandula got an idea. He rolled the cube several yards so it was beneath the fruit. He placed his two front feet on the cube, stretched his trunk as high as he could, and plucked the fruit off the branch. The next day, as soon as Preston suspended the fruit, Kandula was already shoving his cube into place. He seemed to enjoy his new tool. He used it to peek over walls, to check out birds in a nearby tree, and to eat blossoms off another tree that grew outside his yard.
Later, Kandula showed off by using a tractor tire and then a large ball as a stool. He even figured out that if he stacked one small block on top of another he might be able to reach higher fruit. Although he came up short (he needed to stack 3 blocks), he still showed that his brain was working out the problem.
So, congratulations! If you said you’d use a stool to reach your favorite snack, then you are as smart as an elephant.

A celebrity has just arrived in Mr. Madison’s classroom at El Verano Elementary School and the 3rd graders are beside themselves. “Here he is!” they exclaim as the visitor walks through the door.
This special guest has not come to give a lesson or tell a story. He is neither a star athlete nor a movie star. He doesn’t play an instrument, sing, dance or do magic tricks. His tricks are mostly limited to sit, stay and shake. He is a dog. His name is Fenway Bark.
An eight-year old chocolate-colored Labrador retriever, Fenway has been coming to El Verano for six years with his owner, Mara Kahn. He has helped hundreds of children become better readers. Fenway is a literacy dog.
“Fenway’s job is to listen while you’re reading,” explains Mara to the class, which is gathered in a circle around her and Fenway.
One of the best ways for children to improve their reading is to read aloud, but reading in front of an audience can be scary. What if Chelsea mispronounces a word? Or if Alex loses track of where he is on the page? Will everyone laugh? The fear can discourage some children from reading aloud at all.
Solution: read to a totally non-judgmental audience that doesn’t care what you read or how you read it. Read to a dog! When reading to dogs, young readers don’t have to worry about saying “whoof” when they meant to say “which.” With less anxiety and more confidence, young readers increase their reading fluency. That’s why literacy dogs visit hundreds of schools and libraries as reading buddies for children.
Vanessa sits cross-legged on the rug in Mr. Madison’s classroom. She gingerly opens Strega Nona by Tomie De Paola. Softly, slowly, she reads about Big Anthony who ignores Strega Nona’s instructions not to touch her magical pasta pot. Fenway sits up and looks at Vanessa. He gazes at the floor. Vanessa keeps reading. The pasta starts flowing. Fenway stretches out. Vanessa reads a little louder, a little faster. Pasta floods the town. Fenway licks Vanessa’s knee. She giggles and goes back to her book.
Today, six children got to read to the canine visitor. “It’s so cool to read to a dog,” said one boy who will get his chance next week. He was already thinking about choosing a doggone good book

Polar bears are built to withstand some of the coldest temperatures on the planet. Their brown and black bear cousins avoid the winter cold by digging dens and sleeping. But, except for pregnant females, polar bears spend the arctic winter outside where temperatures could be -40° F (which equals-40 °C) and windy. That’s too cold for humans. You could go outside, but only for only a few minutes with every part of your body completely covered. And if you didn’t wear goggles, your eyelashes would freeze and break off if you touched them.
Polar bears are warm-blooded like us with a body temperature of about 98°F/37°C. But they are invisible to night-vision goggles that pick up the infrared rays that warm-blooded creatures, including humans, give off. Why? Nature has given polar bears enough insulation to prevent body heat from escaping. They are toasty warm and comfortable in the frigid arctic.
Their heat insulation is in several layers. Under their skin, there is a 4-inch (21.5 cm) layer of fat. Next to the skin is a dense layer of woolly fur that also keeps heat in. The fur you see is a thick layer of long, colorless guard hairs that shed water quickly after a swim. They are stiff and transparent and hollow. In the arctic sunlight, the hairs act like mirrors and reflect white light, which acts as camouflage against the snow so the bears are not seen by their prey. Polar bear skin is actually black, so that it can absorb the invisible warm infrared rays of the sun and the bear’s own body heat, both of which are reflected back by the guard hairs.
Most warm-blooded animals raise their body temperatures through exercise. Polar bears hunt seals, which they don’t often chase. They prefer to sit at the edge of an ice floe and wait for dinner to arrive. At best, they’ll lumber after a seal at four and a half miles (7.25 km) an hour, raising their body heat to 100°F (38°C). When that happens, they go for a swim to cool off.
Cold won’t kill off the polar bears, but global warming can. As polar ice disappears, so does the hunting ground for seals. Not so cool!
Close up, the polar bear guard hairs are transparent. This allows the infra-red light (heat) from the sun to pass through them to be absorbed by the black skin under the hairs. The hairs also act like mirrors , reflecting back to the skin any infra-red radiation escaping from the bears body so it can be reabsorbed. Thus, the insulation is just about perfect with no infra-red radiation escaping. The hairs are also coated with oil so they drain quickly after a swim.
Vicki Cobb's This Place Is Cold shows how the latitude of Alaska affects the lives of the plants, animals and people who live there. It is gloriously illustrated by Barbara Lavallee, a long-time Alaskan resident and artist.
