How scientists created fake muscle full of real protein

Science is always making advances to further help the lives of amputees, from providing more control over prosthetics, to creating lighter, more comfortable solutions. Some scientists even hope to allow amputees to regrow their own limbs one day! While we wait for this possibility, a research Read More...

Here’s how we can make buildings that capture and store CO2

If we are to successfully reverse the effects of climate change, then we must thoughtfully construct buildings that soak up carbon dioxide rather than produce it. But in order for that to happen, the building trade needs to redirect its focus. So much of the focus of "green buildings" is on Read More...

AI traffic lights could make traffic flow way more efficient

We’ve all been there—running late and trapped behind a red light, even though there’s little to no traffic flowing on the other side. This is made even more frustrating if it happens to be one of those traffic lights in your town or city that, for some reason, always remains red for what Read More...

Industry is finally taking PFA

Industry is finally taking PFAS destruction technologies seriously

What are PFAS? Per- and polyfluoroalkyl substances (PFAS) are widely used chemicals that break down very slowly over time thanks to the extreme strength of the carbon-fluoride bond. Due to their long lasting nature, they are used in clothing, furniture, heat-resistant non-stick cooking surfaces, Read More...
