Research often involves teams of scientists collaborating across continents. Now, using the power of the Internet, non-specialists are participating, too. Citizen Science falls into many categories. A pioneering project was SETI@Home, which has harnessed the idle computing time of millions of participants in the search for extraterrestrial life. Citizen scientists also act as volunteer classifiers of heavenly objects, such as in Galaxy Zoo. They make observations of the natural world, as in The Great Sunflower Project. And they even solve puzzles to design proteins, such as FoldIt. We'll add projects regularly—and please tell us about others you like as well.
The laughter of tiny babies is not just a phenomenally popular theme for YouTube videos, it is also a fantastic window into the workings of the human brain. You can’t laugh unless you get the joke. At the University of London's Birkbeck Babylab we study how babies learn about the world. We believe that studying early laughter in detail will throw new light on the workings of babies’ brains, as well as offering new insights into the uniquely human characteristic that is humor.
We are researching just what makes babies laugh by conducting the largest ever global survey of early laughter. If you are parent with a child under two, you can take the survey. It takes about 15-20 minutes to complete.
We are also interested on particular incidents that made your baby laugh. Who was present? What was so funny? You can file a 'field report'.
Humans' inborn "number sense" improves during school years, declines during old age and remains linked throughout the entire lifespan to academic mathematics achievement. So says a Johns Hopkins University study that has used the Web to collect data from more than 10,000 people ages 11 to 85. "Number sense" describes human and animals' inborn ability to intuitively size up the number of objects in their everyday environments.
Citizen scientists can take the same test used in this experiment by visiting the Panamath Web site. During the test, participants see a random number of circles on screen for 600 milliseconds (0.6 seconds). Their job is to decide whether there were more yellow circles or more blue circles.
Panamath measures a participant's Approximate Number System (ANS) aptitude. The simple task of deciding whether there are more blue dots or yellow dots in a brief flash says a lot about the accuracy of one's basic gut sense for numbers. Participants can view the results of their test immediately afterward and compare their performance with others in their age group.
