Evolution of Dogs And How They Communicate With Humans

Over the years of dogs being domesticated, dogs evolved in ways to better communicate with their human companions. Dogs evolved something that wolves do not have, they evolved small muscles around their eyes that allow them to raise their inner eyebrow to communicate.
My reaction to this article is that I never realized how evolved dogs were, or how intelligent they were. They use only a small muscle to communicate with humans, who they depend upon for survival.

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

Acid Zone in Chesapeake Bay Found

     According to the University of Delaware, the Chesapeake Bay is becoming acidic as it has gone to 7.4 pH from an average of 8.2. The oxidation of ammonia and hydrogen sulfide may be the factor that is leading to the higher acidity levels in coastal oceans, but it can eventually lead to more of open oceans. Naturally the waters of the Chesapeake Bay have a regulatory system that holds back the increase of acidity levels in the area, and this works as the dissolving of living shells, non-living aragonite, and calcite minerals. Though nature has a path to keep the waters in the Chesapeake Bay, humans should take more care of our Earth as we have a role in polluting the water and rising the acidity levels in coastal oceans. https://www.sciencedaily.com/releases/2017/08/170828093737.htm
