The National Inventors Hall of Fame The Inventors Hall of Fame, located in Akron, Ohio, was established in 1973 by the National Council of Patent Law Associations, now the National Council of Intellectual Property Law Associations, and the Patent and Trademark Office of the U.S. Department of Commerce. The year of induction is in parentheses at the end of the entry.

Polar Bears and Climate Change Floods. Droughts. Heat waves. Massive storms. Mitosis and Meiosis - Comparison Chart, Video and Pictures Cells divide and reproduce in two ways: mitosis and meiosis. Mitosis is a process of cell division that results in two genetically identical daughter cells developing from a single parent cell. Meiosis, on the other hand, is the division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each possessing half the number of chromosomes of the original cell. Mitosis is used by single-celled organisms to reproduce; it is also used for the organic growth of tissues, fibers, and membranes. Meiosis is found in sexual reproduction of organisms.

Dental activities for students: Quizzes & lesson graphics - Tooth identification Animated-Teeth.com offers a number of quizzes (with pre-test study pages) that teachers and instructors can use as part of a classroom activity or online lesson aimed at educating students about dental health topics. Subjects include tooth identification and dental, oral and facial anatomy. The skill level required for each activity varies widely.

The clearest proof we’ll ever get that our planet is falling apart Every once in a while, a chart or statistic or image comes along that reminds us, all over again, why it is that this global warming thing is so terrifying. This week, it was those darn walruses, who — after a summer when Arctic sea ice was at its sixth-lowest level on record — mobbed an Alaska beach in the largest such haul-out ever observed there. Salon was on the story. So, too, was pretty much everyone else who writes about climate issues, and we were all trying to get across the same basic idea: Those 35,000 walruses with nowhere else to go are climate change. Or at least, one of the best ways we have of understanding it.

Active and Passive Transport Active and passive transport are biological processes that move oxygen, water and nutrients into cells and remove waste products. Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. On the other hand, passive trasport moves biochemicals from areas of high concentration to areas of low concentration; so it does not require energy.

There may be a lot we don’t know, but here are a few interesting facts that we’ve got covered. Nerve impulses to and from the brain travel as fast as 170 miles per hour. Ever wonder how you can react so fast to things around you or why that stubbed toe hurts right away? It’s due to the super-speedy movement of nerve impulses from your brain to the rest of your body and vice versa, bringing reactions at the speed of a high powered luxury sports car.The brain operates on the same amount of power as 10-watt light bulb.

Biology Archives - Science Sparks Playing Detective – add some science to role play This post is all about adding a bit of science sparkle to role play, the activities should hopefully add a simulating and educational twist to an already fun game. My little boy is usually a bit reluctant to play role play games, but generally if I add in a task or some props he is much more enthusiastic. Here are just a few of our favourite ideas.

Slavery at its worst in Africa; U.S. is no saint either JOHANNESBURG — Slavery persists in the world. It is even still found in the United States, a new report said Thursday. But nowhere is it worse than in Africa. Nearly 30 million people are enslaved around the world, according to the Global Slavery Index. Of the 50 countries where slavery is at its worst, 38 are in Africa, it said.
