Science Behind Why Cracking Knuckles Can Be So Noisy

There recently has been scientific debate over what causes the noise when someone cracks their knuckles. A new study suggests that this noise is caused by a partial collapse in the small bubbles of air in joint fluid. 

Personally, I find this to be very interesting because I crack my own knuckles. I never really gave it much thought as to why cracking my knuckles can make such a loud noise.

    I wonder what this would do to help in the debate that "cracking your knuckles will give you arthritis"... many people do not know why or how knuckles will make that noise.. and most people think of the noise as the joints being popped out of socket.

    This scientific debate is very interesting to me because I constantly am cracking as many bones as I can. This is definitely something i never put a lot of thought into and have done it for the longest time just as a force of habit.

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
