Image Credit: Shutterstock/peterschreiber.media The car industry is starting to get behind hydrogen fuel cells to limit fossil fuel emissions. Fuels cells are a promising technology that could help the automotive industry massively reduce fossil fuel usage by converting hydrogen into electricity. Just as is the case with any emergent technology, adapting hydrogen fuel cell tech to be as efficient and as cost-effective as possible requires investment. A new positive step in this direction comes ...

The Development of Stronger Cobalt for Fuel Cells Image Credit: Pacific Northwest National Laboratory New research has found cobalt could be a cheaper alternative for platinum in PEM fuel cells, a discovery that could lead to increased usage and reduced dependence on fossil fuels.  Electric vehicles that use fuel cells are an important step in cutting greenhouse emissions and our attempts to limit climate change. These cells can be used to generate electricity from oxygen and compressed hydro...

How Gold Nanoparticles Can Be Used to Kill Bacteria Image Credit: Shutterstock/ TAW4 Researchers have identified the physical mechanism that allows gold nanoparticles to effectively kill bacteria. The finding could lead to wider applications in the medical field. It has been understood for some time that certain nanoparticles can kill bacteria, but the mechanism that causes this has, thus far, been something of a mystery. This hasnt stopped nanoparticles from being adopted as an antibacterial...

Using a Graphene-Based Electrochemical Sensor to Detect COVID-19 in Under Five Minutes Image Credit: Shutterstock.com/ Forance A new graphene-based sensor could speed up the detection of COVID-19, helping limit this global pandemic. The COVID-19 crisis has changed the way we think about diseases and viruses and the approaches we use to tackle them. Combating this global pandemic requires multiple strategies and whilst many researchers focus on producing vaccines, others are developing improved...

Coral Recovery Following Prolonged Heatwaves UVic marine biologist Julia Baum sampling Platygyra colonies on Kiritimati (Christmas Island), 2019. Image Credit: Kristina Tietjen. Coral reefs could bounce back from bleaching caused by soaring temperatures new research suggests, but only in the right conditions. Coral reefs have provided researchers with some hope that at least one element of nature could ‘bounce back’ from soaring temperatures and a global heatwave induced by climate change �...
