As scientists frantically try to find drugs to slow COVID-19's spread, citizen science offers an opportunity for all of us to get involved.
A behavioural science expert, a botanist, an environment media expert and an entomologist suggest ways to connect with nature in your garden.
A mylar balloon at Presqu'ile Provincial Park in Ontario, Canada.
Releasing balloons at weddings and other celebrations is festive, until they break into pieces and become plastic pollution. A citizen science project is spotlighting the problem.
Yellow trout lily flowers nearly a week earlier now than in previous decades in the Appalachian Mountains.
Climate change has advanced the arrival of spring by as much as several weeks in some parts of the US. This can mean major crop losses and disconnects between species that need each other to thrive.
Costa’s Hummingbirds are frequent visitors at feeders in Arizona and southern California.
Millions of Americans feed wild birds, especially in winter and spring. Studies show that this can influence birds' health and behavior in surprising ways.

The predatory flatworm Obama nungara travelled in potted plants from Argentina to Europe, where it's distrupting soil ecosystems. Now, citizen-scientists are helping map their distribution.
Scientists can now track butterfly migration in real time with the help of volunteers.
Citizen scientists across North America have contributed over 1 million observations to this online platform, generating data useful for researchers.
Although yellow fever does not currently exist in Australia, the species Aedes aegypti - which can transmit the disease - is found widely across northern Queensland. The virus remains a global health concern, but citizen scientists could help prevent its spread.
Nuisance-biting and mosquito-borne disease are ongoing concerns for health authorities. But an effective citizen science program is now showing how all of us can help beat the bite of mozzies.
What can your vacation pix tell scientists?
To untangle the relationship between climate change, fall foliage and national park visitors, researchers are asking tourists to check their old photo albums for snapshots that could hold valuable data.

Governments need better information on which types of plastic generate the most pollution — citizens can help.
Beinecke Rare Book & Manuscript Library
The Voynich Manuscript has researchers, the media, and the public hooked. But pseudo-explanations for the book's 'code' reveals a serious problem with society's relationship with science.
If you are bitten by a tick that is infected with Lyme disease, a single dose of antibiotics can prevent an infection from developing, if administered within 72 hours of tick removal.
If you are bitten by a tick, you need to find out what species it was, fast. A research team has developed a website to help people in Quebec, Ontario and New Brunswick do just that.
Bank swallows, like this juvenile, may become endangered unless habitat loss and other threats are reduced.
A collection of millions of bird sightings has identified the best places to invest in conservation.
A safe, connected network of bike lanes and paths encourages cycling.
Volunteers can contribute data to maps that help cyclists choose their routes and let planners know how city cycling can be improved.
Camera traps allow citizen scientists to peek into the hidden lives of Britain's mammals.
Honey can carry clues about where pollutants come from.
Urban pollutants are a health concern in growing cities. Scientists are turning to honey bees to help monitor contaminants in soil, water, air and plants.
Project Oceanology class retrieves a bottom trawl at the mouth of the Thames River.
For decades, New England students took field trips out into the Long Island Sound. Their data show how quickly the sound is warming, leading to fewer American lobster, rock crab and winter flounder.
Fleas, as pet owners know, are a common menace.

By finding out more about the cat flea, researchers could maybe identify better pest control measures.
Citizen science can help address data deficits.
Citizens can be recruited in addressing data deficits.
Wood smoke may smell good, but it is not good for you.
The smoke from wood-burning stoves and fireplaces contributes to air pollution and poor health.
