  When I first became involved in online professional development (PD) courses about 10 years ago, the casual approach to participation in terms of time and attire were often noted as desirable features. An often-touted advantage to online PD was that individuals could participate at 3 a.m. wearing pajamas and bunny slippers. Over the years, […]

SciStarter asked Craig Newmark (of Craigslist fame) why he likes squirrels. He told us that it all started with a simple desire to feed birds. But the suet palaces he was using to dispense the raw, fat-based bird food were constantly getting hacked by squirrels. He tried everything; he even upgraded to “squirrel-resistant” models, to […]

What would it be like without stars at night? What is it we lose? Starry night skies have given us poetry, art, music and the wonder to explore. A bright night sky (aka “light pollution”) affects energy consumption, health and wildlife too. Spend a few minutes to help scientists by measuring the brightness of your […]

As cold and flu season approaches in the Northern Hemisphere, many people are starting to think about what they can do to avoid getting sick. To help prevent illnesses, public health advice needs to be based on solid scientific evidence. The Health Tracking Network is a citizen science project designed to fill some of these […]

RESTON, Va. — Thanks to citizen-scientists around the country, the USA National Phenology Network hit a major milestone this week by reaching its one millionth nature observation. The millionth observation was done by Lucille Tower, a citizen-scientist in Portland, Ore., who entered a record about seeing maple vines flowering. Her data, like all of the […]

Sergei Winogradsky discovered nitrifying bacteria in 1890, recognizing that these microbes convert ammonia to nitrate (via nitrite). In aquatic environments, ammonia toxicity to fish is avoided almost exclusively due to the activity of these bacteria…or so it was thought. The ability to remove (or oxidize) ammonia was discovered recently in Archaea, which are an entirely […]

For most people, a citizen science project provides a way to address a specific scientific challenge with the help of volunteers. For a group of researchers from MIT, UCSD, Masdar Institute, and University of Southampton, it is also an opportunity to study what motivates people to join the project. Would you rather receive a badge, […]

Most of us are aware of the bacteria on the surfaces we come in contact with. The doorknob for the bathroom, coins and paper currency in our pockets, handrails in subway cars, computer keyboards and mice at the library… the list of built environments on which microbes thrive is nearly endless. In our preoccupation with […]

The Sungrazer project allows amateur astronomers world-wide to discover comets in images from NASA’s SOHO and STEREO missions… now with over 2000 discoveries!

In July of 2009, a friend and I arrived at a lake to collect water samples for work. We had worked at the lake many times, but something was different that day: several hundred dragonflies were flying over the grass. We often saw dragonflies, but there were 50 times the usual number and they weren’t […]
