The world is supposed to share the cost of fighting climate change. Here's how that works
One of the key tenets of the 2015 Paris Agreement was that richer countries such as Canada would provide financial assistance to developing countries to help them achieve their climate targets. We take a look at how the financing is supposed to work and how countries are doing in meeting the promised $100 billion US a year...

FDA-approved iron oxide nanoparticles, delivered in a mouth rinse, can suppress the growth of dental plaque and kill bacteria responsible for tooth decay, according to a new study. The nanoparticles act as enzymes to activate hydrogen peroxide in a way that precisely targets harmful microbes and spares normal tissue.

Methane emissions from the distribution and use of natural gas across U.S. cities are 2 to 10 times higher than recent estimates from the Environmental Protect Agency, according to a new study. In Boston, methane emissions from the natural gas system are six times higher than recent estimates by the Massachusetts DEP and have not significantly changed in eight years, despite legislation aimed at...

Brain cells called astrocytes play a key role in helping neurons develop and function properly, but there's still a lot scientists don't understand about how astrocytes perform these important jobs. Now, a team of scientists has found one way that neurons and astrocytes work together to form healthy connections called synapses. This insight into normal astrocyte function could help scientists...
