Sleep: Genes Cause People to React Differently to Lack of Sleep, Says Study <br/><a href=" US News</a> | <a href=" Business News</a> Copy No matter how little they sleep, some people can keep a skip in their step while others will yawn and struggle through the day. A new study from the University of Pennsylvania School of Medicine found that the reason could be in our genes. Researchers found that healthy people with one particular genetic variant were generally sleepier than those without the gene. About 25 percent of the general public has the genetic variant, called DQB1 *0602, but only a small percentage of them actually suffer from sleep problems. One person who has been told by his doctor that he may have this genetic variation is Robert Gibson, a 43-year-old machine shop supervisor in Milan, Illinois. "It feels like I am drugged down, like there's a heavy weight on me the whole next day," said Gibson. Genes and Heavy-Eyes
Science/Nature | Dolly scientist abandons cloning The scientist who led the team that controversially created Dolly the sheep is abandoning the cloning of human embryos in stem cell research. Professor Ian Wilmut, of Edinburgh University, believes a rival method developed in Japan holds the key to curing serious medical conditions. The new method creates stem cells from fragments of skin and could remove the need to use human embryos. Pro-life groups opposed to the use of embryonic cells have welcomed the move. But Prof Wilmut said: "We've not made this decision because it's ethically better. "To me it's always been ethically acceptable to think that if you could use cells from a human embryo to develop a treatment for a disease like motor neurone disease, for which there is no treatment at present, then that is an acceptable thing to do." Building blocks The professor's team developed a cloning technique that has subsequently been used to harvest stem cells - which have the potential to be grown into any cell in the human body.
Home of CELLS alive! Biology | 7.03 Genetics, Fall 2004 | Lecture Notes Scientist creates lifelike cells out of metal Scientists trying to create artificial life generally work under the assumption that life must be carbon-based, but what if a living thing could be made from another element? One British researcher may have proven that theory, potentially rewriting the book of life. Lee Cronin of the University of Glasgow has created lifelike cells from metal — a feat few believed feasible. The discovery opens the door to the possibility that there may be life forms in the universe not based on carbon, reports New Scientist. Even more remarkable, Cronin has hinted that the metal-based cells may be replicating themselves and evolving. "I am 100 percent positive that we can get evolution to work outside organic biology," he said. The high-functioning "cells" that Cronin has built are constructed from large polyoxometalates derived from a range of metal atoms, like tungsten. The metallic bubbles are certainly cell-like, but are they actually alive? The early results have been encouraging.
Cracking the Code of Life Cracking the Code of Life PBS Airdate: April 17, 2001 ROBERT KRULWICH: When I look at this—and these are the three billion chemical letters, instructions for a human being—my eyes glaze over. But when scientist Eric Lander looks at this he sees stories. ERIC LANDER (Whitehead Institute/MIT): The genome is a storybook that's been edited for a couple billion years. ROBERT KRULWICH: This is the story of one of the greatest scientific adventures ever, and at the heart of it is a small, very powerful molecule, DNA. For the past ten years, scientists all over the world have been painstakingly trying to read the tiny instructions buried inside our DNA. J. FRANCIS COLLINS (National Human Genome Research Institute): This is the ultimate imaginable thing that one could do scientifically...is to go and look at our own instruction book and then try to figure out what it's telling us. ROBERT KRULWICH: And what it's telling us is so surprising and so strange and so unexpected. I'm Robert Krulwich. DR.

Cloning & Synthetic Biology Overview of Traditional Cloning Traditional Cloning refers to the generation of DNA fragments using restriction enzymes, and their subsequent assembly and transformation. The name is derived from the method’s history as the first widely-accepted cloning method. Learn more about the benefits and disadvantages of Traditional Cloning. scroll to see additional videos
Human Body Board Game Subjects Science --Life Sciences ----Biology Grade 3-5 [facebookbadge] Brief Description Students research a system of the body, write questions and answers on game cards in Word, and then play the using a game board template from Word. Objectives Students will: gain understanding of the basic facts about systems of the human body. select the most important facts about a specific body system. Keywords human body, anatomy Materials Needed[shopmaterials] Student access to computers equipped with Microsoft Word. Lesson Plan Before beginning this lesson with students, you'll need to create a template for the game cards. This lesson works best at the end of a unit on the human body, when students have acquired some basic knowledge about the various body systems (circulatory, digestive, etc.). Arrange students into groups of 2-3. Whether you decide to have students play the game in groups or as an entire class will determine the number of game boards you need.

23andMe presents top 10 most interesting genetic findings of 2010 Public release date: 12-Jan-2011 [ Print | E-mail Share ] [ Close Window ] Contact: Jane E. MOUNTAIN VIEW, CA – January 11, 2011 – 23andMe has released its first annual list of what it felt to be the 10 most interesting and significant genetic findings in 2010, as part of an ongoing journey to understand the role of genetics in personal health and human development. "Our understanding of the human genome is accelerating at a phenomenal rate," stated Anne Wojcicki, co-founder and CEO of 23andMe. Customers of 23andMe have the opportunity to learn about how their genetics can influence their individual health traits, risk for developing certain diseases and conditions, reactions to a variety of medications, and ancestry. 1.

Report Finds GE Crops Benefit Farmers, But Management Needed to Maintain Effectiveness Read Full ReportPowerpoint PresentationReport in BriefListen to the BriefingPhotos Date: April 13, 2010 Contacts: Jennifer Walsh, Media Relations Officer Molly Galvin, Senior Media Relations Officer Alison Burnette, Media Relations Assistant Office of News and Public Information 202-334-2138; e-mail <news@nas.edu> Genetically Engineered Crops Benefit Many Farmers, But The Technology Needs Proper Management to Remain Effective -- Many farmers who grow genetically engineered (GE) crops are realizing substantial economic and environmental benefits -- such as lower production costs, fewer pest problems, reduced use of pesticides, and better yields -- compared with conventional crops, says a new report from the National Research Council. The report provides the first comprehensive assessment of how GE crops are affecting all farmers, including those who grow conventional or organic crops. Environmental Benefits Economic and Social Effects The study was funded by the National Research Council. Pullman
