Encourage kids to explore, experiment and invent with STEM toys that promote critical and creative thinking in young minds. In a world dominated by computers, these STEM learning toys offer screen-free and immersive ways to grasp scientific concepts, logic and promote problem solving. Toddler STEM toys like LEGO building blocks and vocabulary flash cards lay the foundation for the school curriculum, while helping kids develop their fine motor skills. The next level of toys make sure that a child is exposed to logical thought and inquiry from a young age. This helps build interest in the sciences and offers a hands-on way to discover and learn. STEM kits for older kids encourage scientific explorers to stretch the boundaries with interactive robots, microscopes and beginner kits for rocket sciences or geology. Filter 1.

I was ready to head home after giving a lecture about Inferior —my book documenting the history of sexism in science and its repercussions today —when a soft-spoken woman approached me. She told me she was studying for a Ph. He never picked her for workshops or conferences. The scientific establishment has long had a woeful record when it comes to women. Charles Darwin , no less, described women as the intellectual inferiors of men. Toward the end of the European Enlightenment, in the late s, it was assumed that women had no place in academia. Many universities refused even to grant degrees to women until the 20th century; my alma mater, Oxford University, waited until

Those experiments will surely be followed by many others around the world, as teams in China, the U. RWG: Honestly it was an uncomfortable adjustment. George W. The scientists have repeatedly moved each cell's offspring to less crowded laboratory dishes, allowing them to divide again and again. No such obstacle faced Woo-Suk Hwang and his colleagues at Seoul National University in February when they became the world's first to clone human embryos and extract stem cells from them.

He hopes to get FDA permission to start testing the cells in people with spinal cord injuries in National Geographic Sensory Science. The bear received a checkup before being fitted with a GPS collar to track her movements. For one thing—and for reasons not fully understood—the surest way to keep these cells alive is to place them on a layer of other cells taken from mouse embryos, a time-consuming requirement. See all.

For years Thomson and his colleagues have been expanding some of those original stem cells into what are called stem cell lines—colonies of millions of pluripotent cells that keep proliferating without differentiating into specific cell types. Most were relatively routine—until a strong-willed fertility doctor named Alison Murdoch decided to ask for permission to do something nobody had done before: create cloned human embryos as sources of stem cells.

In church pews, congressional hearing rooms, and finally the Oval Office, people wanted to know: Where were the needed embryos going to come from, and how many would have to be destroyed to treat the millions of patients who might be helped? Advocates counter that adult stem cells, useful as they may be for some diseases, have thus far proved incapable of producing the full range of cell types that embryonic stem cells can. Use whatever privilege you have—and we all have some kind of privilege—to be there as an ally for someone else.

I am an American, after all. Some states have already passed legislation banning various kinds of embryo research. And while they worked, the nation struggled to get a handle on the morality of what they were doing. Mom and dad, who have spent hours in prayer, nod yes, and a line of crimson wends its way down the tube, bringing the first of about million cells into the boy's body. For one thing—and for reasons not fully understood—the surest way to keep these cells alive is to place them on a layer of other cells taken from mouse embryos, a time-consuming requirement. I ask Ross Thacker, a research officer at the authority, whether the HFEA is regularly in need of yellow police tape to keep protesters at bay. To break down those harmful stereotypes—"this is what a scientist looks like"—is really important. RWG: My work is about saving animals from extinction, and so many other scientists are also trying to save the planet so we can survive.
