This inspiring story of the first female doctor shows how one strong-willed woman opened the doors for all the female doctors to come.

    Is there enough time? You have 3 shirts and 2 pairs of pants. Can you make 1 good outfit? Then you start to wonder: Why does everything have to be such a problem?

    All around the world -- in the sea, in the soil, in the air, and in your body -- there are living things so tiny that millions could fit on an ant's antenna. They're busy doing all sorts of things, from giving you a cold and making yogurt to eroding mountains and helping to make the air we breathe. If you could see them with your eye, you'd find that they all look different, and that they're really good at changing things into something else and at making many more microbes like themselves! From Nicola Davies comes a first exploration for young readers of the world's tiniest living organisms.

    Zip. Zilch. Nada. That's what all the other numbers think of Zero. He doesn't add anything in addition. He's of no use in division. And don't even ask what he does in multiplication. (Hint: Poof!) But Zero knows he's worth a lot, and when the other numbers get into trouble, he swoops in to prove that his talents are innumerable.

    Like her mother, she had a passion for science, math, and machines. It was a very good combination. Ada hoped that one day she could do something important with her creative and nimble mind.A hundred years before the dawn of the digital age, Ada Lovelace envisioned the computer-driven world we know today. And in demonstrating how the machine would be coded, she wrote the first computer program. She would go down in history as Ada Lovelace, the first computer programmer.Diane Stanley’s lyrical writing and Jessie Hartland’s vibrant illustrations capture the spirit of Ada Lovelace and bring her fascinating story vividly to life.

    On a cold January day in 2017, nearly two months before her due date, Nile hippopotamus Bibi gave her keepers at the Cincinnati Zoo & Botanical Garden a big (little) surprise - a tiny newborn hippo, no bigger than a football.  The first premature hippo born and raised in captivity, baby Fiona was an underdog from the start:  she couldn't nurse, she couldn't stay hydrated, and she wasn't thriving. But the staff at the zoo knew they could save her.  It would take creative thinking and teamwork. They would have to study the makeup of hippo milk for the first time ever and reach out to medical colleagues, including a team at the local Children's Hospital with superior vein-finding skills,  to ensure that Fiona would begin to gain weight and become healthy. When Fiona began to thrive, her star began to rise, and soon she became an internet sensation, her picture and videos garnering thousands and thousands of likes and fans on Instagram and Facebook.  Now a Fiona appearance at the Zoo mimics a Beatles concert.  What made this little, now big, hippo such a big hit with people all over the world?  And what's in store for her and her family in the future?
