Curiosity Machine More Beta Cells, More Insulin, Less Diabetes Caption: Betatrophin, a natural hormone produced in liver and fat cells, triggers the insulin-producing beta cells in the pancreas to replicateCredit: Douglas Melton and Peng Yi Type 2 diabetes (T2D) has arguably reached epidemic levels in this country; between 22 and 24 million people suffer from the disease. But now there’s an exciting new development: scientists at the Harvard Stem Cell Institute have discovered a hormone that might slow or stop the progression of diabetes . T2D is the most common type of diabetes, accounting for about 95% of cases. Treating diabetes costs the U.S. a veritable fortune. The NIH-funded researchers set out to try to identify a signal that seems to be sent by the liver to the beta cells when the insulin receptor is blocked and blood glucose levels rise. Betatrophin sends the beta cells into a frenzy causing them to replicate as much as 30 times their normal rate! It’s not every day that a new and important hormone is discovered! References: Links:
The Science of Life: How your body works | Physiological Society Understanding Life Following the huge success of our competition - The Science of Sport: How to Win Gold - last year, we are pleased to launch another school research competition again in 2013: The Science of Life: How your body works. As the title suggests, the new competition will have a much broader theme and projects from all areas of physiology will be accepted. Open to all 16-19 year-olds studying towards their A-levels or equivalent qualifications, the competition will give students the chance to design and carry out their own research project on a physiological topic that interests them, and then present their findings to scientists at a major scientific conference in London during the summer of 2014. Gold, Silver and Bronze prizes will be awarded to the top three projects at the meeting including a visit to the Centre of Human and Aerospace Physiological Sciences at King's College London.
Great Websites to Teach Anatomy of Human Body in 3D September, 2014 looking for some amazing web tools to teach human anatomy? The websites I have assorted for you below are probably among the best you can find out there. From engaging interactives to live simulations of the body system, these tools will enable your students to explore the mystery of the human body in unprecedented ways. Some of these tools provide 3D imaging of parts of the human body so students will both learn and live the experience of discovering the hidden secrets of our body. 1- Visible Body Visible Body offers students 3D anatomical models of the human body. 2- Zygote Zygot provides students with a virtual lab with 3D dimensions where students can learn about dissection and human anatomy. 3- Inner Body Inner Body is a web tool that allows students to explore the human body using a large array of interactive pictures and through descriptions of thousands of objects in the body. 4- Get Body Smart 5- Virtual Body Virtual Body is a web tool provided by MEDtropolis.
Beginner's Guide to Aeronautics In the 21st century, airplanes are a normal part of everyday life. We see them fly over, or read about them, or see them on television. Most of us have traveled on an airplane, or we know someone who has. Do you ever wonder how airplanes fly? The web site is divided into Beginner's Guides about a single topic. The Beginner's Guide to Aeronautics has been on the web for over a dozen years. Much of the material in the Beginnner's Guides to Aerodynamics and Propulsion was originially developed for NASA's Learning Technologies Project (LTP). For many of the web pages, activities are available for teachers to use in class. Elementary and middle school teachers at two workshops sponsored by LTP in 1996 and 1997. At each Beginner's Guide index, there is a link to an index of the teacher-generated activities related to the topic. The web site was prepared to provide background information on basic aerodynamics and propulsion for math and science teachers, students, and life-long learners.
NH Field Investigation Models Using Field Investigations to Model Scientific Inquiry State and national science standards emphasize the importance of inquiry and problem-solving for today’s students. Field investigations offer rich opportunities for students to practice inquiry in engaging and authentic ways. Key steps in field investigations mirror the inquiry process. They are posing research questions, planning and conducting investigations, using evidence to describe findings, communicating research findings to target audiences, and asking new research questions based on findings. Beyond Data Collection Just as New Hampshire is gifted with abundant natural resources, so too do we benefit from plentiful scientific field investigations. Maximum and minimum air temperature data collected at Hubbard Brook Experimental Forest.

The details about the following nine word cloud generators will give you a fair idea how, as an educator, you can get the best out of them. A quick note: Wordle is quite easily the most popular word cloud generator out there. It’s free and easy to use. It does require Java though so Chrome users might have some trouble. In any case, this article focuses on non-Wordle options you should know about. Tagul Several features that do not figure in Wordle are incorporated in Tagul .For example, you have the option of choosing personalized shapes and multiple fonts to be used in your cloud. ABC Ya This application is very much like Wordle and operates the way Wordle operates. Tag Crowd This application gives you access to see frequency of words. Word It Out Word It Out helps create word clouds from any text, similar to the way Wordle does. Make Word Mosaic Wordsift TagCloudGenerator You Are Your Words
