GOTTA CATCH 'EM ALL Stall Catchers

Alzheimer’s causes reduced blood flow to the brain, but until now, nobody knew why. New, specialized imaging techniques allow researchers to discover why. This suggests new treatments, symptom prevention, and possibly restoring cognitive function. However, understanding specific pharmaceutical targets could take decades, limited by the need for extensive manual image analysis. Crowdsourcing this analysis to volunteers could reduce that time to just a few years.

SUMMER BITES Mosquito Byte!

A very simple smart phone app (for Android or iPhone) that allows a user to report a mosquito bite. The user is rewarded with a fact about mosquitoes, and the bite report is displayed in (almost) real time on a map of the world. The more people use it, the more we know about when and where there are biting mosquitoes.

Over 225,000 people around the world have played the Eyewire puzzle game. Anyone can play without having any knowledge or experience in neuroscience. Eyewire researchers aim to eventually map the human brain, players map the connections between neurons, helping researchers understand how they process information. Players have already helped researchers understand how a mammal can detect motion, which has remained a mystery until now.

FOLLOW THE SUN(FLOWERS) The Great Sunflower Project

Some bee populations are severely declining, which may affect food production. However, nobody has ever measured how much pollination is happening over a region, so there is little information about how a decline in bees can influence gardens. The Great Sunflower Project makes it easy to gather this information. Find a plant, observe it for 5 or more minutes and record all pollinators that visit, and contribute data online. It’s easy!

Vivid cave paintings of nature and ancient lifestyles show our early ancestors paid careful attention to the world around them.

384 - 322 BC

Science and “natural philosophy” were one and the same in Aristotle’s time. He was a “gentleman amateur”, fascinated by weather, animals and just about everything in his environment.

8th Century

Courtiers in Japan record observations of when cherry trees blossom. Those historic records are now used in 21st Century scientific publications, demonstrating altered springtime phenology due to climate change.


The Domesday Book is created through “crowdsourced” local knowledge on wildlife in lands surveyed across England. Although originally intended for tax purposes, the information becomes an important database of natural observations.

14th Century

French vintners carefully record temperature and humidity. Their data generated is used in 21st Century publications demonstrating the climate influences of North Atlantic Oscillations.


Amateur observers around the globe are commissioned by The Royal Society of London, along with Navy Captain James Cook, to view the Transit of Venus across the Sun. From details on the timing of the Transit from different places on Earth, scientists are able to calculate the size of our Solar System.

1776 - 1816

Thomas Jefferson records the weather over a period of more than 40 years, providing an unbroken catalogue of observations. He is considered one of the “Founding Fathers of Citizen Science” in North America, along with another weather geek, Ben Franklin.


Utilizing citizen-generated newspaper reports, Denison Olmsted of Yale crowdsources meteor observations.


Volunteers in the “Great Tide Experiment” record tide levels every 15 minutes for two weeks! Coordinated by Cambridge polymath, William Whewell, participants on both sides of the Atlantic and all around the world monitor over 650 tidal stations. Whewell wins a Royal Medal for his research based on the data gathered by the experiment.


Naval officer, Matthew Maury, later known as the “Father of Oceanography”, crowdsources wind and current information. By speaking to sailors from multiple nations, he creates charts that make sailing safer and faster for all.


The “Lighthouse Keeper Survey” is begun by the newly formed American Ornithologist’s Union. However, the keepers use colloquial rather than scientific names for the birds they observe, making their data largely unusable to the scientific community.

1890 - Now

U.S. Congress establishes The National Weather Service’s Cooperative Observer Program (COOP) which sets up stations around America for volunteers to contribute observations. This citizen sourced data forms the basis of the National Climatic Data Center.

1900 - Now

The annual Christmas Bird Count is founded by dedicated birder Frank Chapman, and continues today through The Audubon Society. Every year around Christmas volunteers follow set protocols for counting birds in a specified “circle.” The CBC is one of the longest running citizen science programs in the United States, and now extends internationally to other countries
