Needleman estimates that lead exposure has already cut in half the number of U.S. children who might have had superior IQs (125 or over) — some 2 million kids.

Recover™ transforms textile waste into sustainable recycled fibers and blens, closing the loop on fashion. You might see waste, we see circular solutions.

Korean researchers have demonstrated that it is possible to create efficient large-area organic photovoltaic cells, opening the door to applications such as plastic-based photovoltaic paint.

Solar paint actually refers to 3 different exciting technologies: hydrogen-producing paint, quantum dots & perovskites. We explain them all in this blog.
Imagine one day fuelling your car with iron powder, rather than gasoline. That’s the goal of some Canadian scientists who hope that metal will one day provide a cleaner, greener alternative for our cars and other vehicles.
Many industries use heat-intensive processes that generally require the burning of fossil fuels, but a surprising green fuel alternative is emerging in the form of metal powders. Ground very fine, cheap iron powder burns readily at high temperatures, releasing energy as it oxidizes in a process…

Why does iron not release energy in fusion or fission? I know it has to do with it having the least mass per proton/neutron, but why is it that way? - Quora
Wow, I so didn’t realise this was the case. So linking to where I landed when Googling it. On stack exchange, someone said this…
“Iron is a “special” element because of its nuclear binding energy. The very basic idea is that when you fuse two light elements together, you get a heavier element plus energy. You can do this up to iron. Similarly, if you have a heavy element that undergoes fission and splits into two lighter elements, you also release energy. Down to iron. You can see this in the plot shown in the wiki article I linked. The physical reason for this has to do with the balance between nuclear forces and the electromagnetic force.
Due to the way these energies work, and because iron is thus thought of as the most stable, if you want to get energy from fusion or fission, your best bet is to use atoms that are farthest away from iron — very light (like hydrogen) or very heavy (like uranium).
As a side note, this is also why Type 2 supernovae happen — the star can no longer gain energy from fusion because it can’t fuse past iron, so the outward pressure from energy generation stops and the star collapses.”

Sixty cities in 15 states are taking a playground approach to sidewalk maintenance. They’re testing rubber sidewalks as a way to avoid the costly repairs of concrete walks that have been broken up by tree roots. Officials say the rubber sidewalks as a win-win. But some residents aren’t so sure.

You can make this beautiful version at instructables.
Not entirely plastic bicycles, but you can buy replacement wheels made of plastic materials.
zillions of options have been suggested. it likely won’t change though. Its; just wrong and likely will be forever. Just to confuse students.
Awesome concept! Check out this company that makes bicycles using plastic bottle caps. And the best part, you can return them to the factory to be recycled when they are too worn out. https://innovationorigins.com/en/startup-of-the-day-cycling-on-a-bicycle-made-of-used-plastic-bottle-caps/
They have been around for some time, though the technology is yet to gain traction. A great way to save the environment by reducing plastic waste.

Polymers are amazing things, before life formed they were the pinnacle of what the universe could make.
