If you’re on the fence about wearing a mask it’s time to come to the side of putting one on. Scientists aren’t sure if it will help but they are sure it won’t hurt and has been helpful in slowing the spread of other, similar illnesses.
Trees are important to fighting the climate crisis but how will they do in a world with less water? Well it turns out they’re already making some changes to survive drier times. As the climate changes, trees are changing with it.
If you are sick, you should isolate yourself new study confirms. By making the choice to stay home, away from others, even if you are only showing A FEW symptoms, you’re helping to stop the spread of COVID-19 and potentially cutting down on how many ICU beds will be needed.
This sounds like the stuff of science fiction but scientists at the University of California are working on a way to create the building blocks organic molecules from bacteria, nanowires, sunlight, carbon dioxide and water like a little replicator.
Today our major greenhouse gas is CO2 but in the past, it was lead. Which isn’t a greenhouse gas but thanks to mining during the 1100s, a lot of it was in the air and man, that could not have been a good time for people breathing it. New ice cores prove that lead pollution was just as bad then as air pollution during the Industrial Revolution which goes to show, we’ve always been pretty bad at this.
The N95 respirator masks are in short supply (along with much of the other needed PPE) and doctors have had to reuse them which puts everyone in danger. Researchers at Duke University have devised a way to decontaminate these masks so that they can safely be reused.
Remember the hole in the ozone layer? It was a big deal in the 80s and 90s. Such a big deal that nations signed the Montreal Protocol and agreed to stop producing chemicals that were destroying the ozone. Well it’s been 33 or so years since that went into effect and good news, the ozone layer has made a come back.
The ocean is pretty harsh when you’re just out there, exposed to the rolling waters. So harsh in fact that it can break down plastics like LEGO bricks which are built tough. We’ve known for a while that the plastic toys could survive for a long time in the sea but scientists have recently discovered that “a long time” could be as much as 1,300 years!
