CERN, the European Organization for Nuclear Research, is one of the world’s largest and most respected centres for scientific research. Its business is fundamental physics, finding out what the Universe is made of and how it works. At CERN, the world’s largest and most complex scientific instruments are used to study the basic constituents of matter. By studying what happens when these particles collide, physicists learn about the laws of Nature.

The Health On the Net Foundation (HON) promotes and guides the deployment of useful and reliable online health information, and its appropriate and efficient use. Created in 1995, HON is a non-profit, non-governmental organization, accredited to the Economic and Social Council of the United Nations. For twelve years, HON has focused on the essential question of the provision of health information to citizens, information that respects ethical standards. To cope with the unprecedented volume of healthcare information available on the Net, the HONcode of conduct offers a multi-stakeholder consensus on standards to protect citizens from misleading health information.

As an unbiased, multi-disciplinary science organization that focuses on biology, geography, geology, geospatial information, and water, we are dedicated to the timely, relevant, and impartial study of the landscape, our natural resources, and the natural hazards that threaten us.

Since its inception in 1958, NASA has accomplished many great scientific and technological feats in air and space. NASA technology also has been adapted for many nonaerospace uses by the private sector. NASA remains a leading force in scientific research and in stimulating public interest in aerospace exploration, as well as science and technology in general. Perhaps more importantly, our exploration of space has taught us to view Earth, ourselves, and the universe in a new way. While the tremendous technical and scientific accomplishments of NASA demonstrate vividly that humans can achieve previously inconceivable feats, we also are humbled by the realization that Earth is just a tiny blue marble in the cosmos.

It started like this. We looked around and noticed changes in the way people were living their lives. It seemed these changes were coming from a few sources: a growing awareness of the state of our planet to what foods we eat; an interest in yoga and inner peace to an exploration of alternative wellness ideas...but there was a central thread: healthy living. We also noticed there wasn't a central place to connect all these interests. That's why we created LIME. Healthy living with a Twist. At LIME, we built a place where you can find all the ideas, information and resources to inspire you to live healthier and help make our planet greener - and have some fun while you're at it. We're all about simplicity and community.
