Dual-fuel vehicles
A recent study shows that dual- fuel vehicles are benefiting the population but, turns out they are costing the environment. While substituting gasoline for ethanol gases, it causes an increase of ultra fine particle matter, with a 30% increase of atmospheric concentration. The problem is that they are less then 50 nanometers in diameter. The nano particles are also not track or regulated by the environmental agencies. We inhale these gases everyday, inhaling ethanol. The most practical way to reduce greenhouse gases is using electric, hybrid and biofuel care. https://www.sciencedaily.com/releases/2017/08/170828124546.htm
I think it's super fascinating that cleaner wrasse fish could possible self-aware. People typically think of fish as unintelligent creatures, but that's clearly not true for this fish. The part where the scientist injected the cleaner wrasse fish with harmless brown gel and then saw the fish attempting to scrape off the gel as if it were a parasite, once they saw themselves in the mirror, was super interesting. Humans do a similar action to this such as popping pimples, once they are aware they have one after looking in the mirror.
