The research and vision of Canadian scientists were key foundations of the Human Genome Project. Today, lack of funding threatens discovery research in Canada. (Pixabay)

Canadian science pioneers’ role in the Human Genome Project shows why it’s crucial to fund research

On DNA Day, Canada should be inspired by the lifesaving discoveries of its researchers. However, lack of funding threatens Canadian researchers’ ability to meet the challenges of the future.

Reading the bones of the dead: the painstaking, painful process of returning genocide victims to their families

How do trees die?

Even in death, a tree helps others live.

How does RNA know where to go in the city of the cell? Using cellular ZIP codes and postal carrier routes

Making sure RNA molecules are in the right place at the right time in a cell is critical to development and normal function. Researchers are figuring out exactly how they get to where they need to go.
Epigenetics is but one of many factors that influence aging, health and disease. bestdesigns/iStock via Getty Images

Epigenetic and social factors both predict aging and health – but new research suggests one might be stronger

People don’t all age at the same rate. Untangling the factors that influence health and disease – such as epigenetics, demographics and behavior – could lead to better care for those who need it most.

By fact-checking Thoreau’s observations at Walden Pond, we showed how old diaries and specimens can inform modern research

Journals, museum collections and other historical sources can provide valuable data for modern ecological studies. But just because a source is old doesn’t make it useful.
