The Reality Check Episode 75

Ginkgo Biloba + Audio Cables + Fugu (Puffer Fish) Myth

Gingko Leaves
Part 1:
So, what is Ginkgo Biloba?
Ginkgo is a unique species of tree with no close living relatives. The ginkgo is classified in its own division, the Ginkgophyta, comprising the single class Ginkgoopsida, order Ginkgoales, family Ginkgoaceae, genus Ginkgo and is the only extant species within this group. It is one of the best-known examples of a living fossil, because Ginkgoales other than G. biloba are not known from the fossil record after the Pliocene.
What does Ginkgo Biloba do? 
It is said that the Ginkgo Biloba remedies can help many kinds of diseases, from depression and memory loss, to headaches and dizziness.
So, there was a study that involved more than 3000 people aged over 72 years. They were all randomly assigned to take Ginkgo Biloba twice a day, or placebo tablets. The overall findings show that Ginkgo Biloba didn't prevent Alzheimer's. Then they decided to see if it helped with memory loss. Then they use a kind of test every 6 months for their mental abilities. By the end of the research, the Ginkgo Biloba didn't help with it at all. It doesn't harm anyone, but it doesn't help either. 
In conclusion, the Ginkgo Biloba remedies doesn't help at all. 

Part 2: 
A cable is two or more wires running side by side and bonded, twisted or braided together to form a single assembly. In mechanics cables, otherwise known as wire ropes, are used for lifting, hauling and towing or conveying force through tension. In electrical engineering cables used to carry electric currents . An optical cable contains one or more optical fibers in a protective jacket that supports the fibers.
Electric cables discussed here are mainly meant for installation in buildings and industrial sites. For power transmission at distances greater than a few kilometers see high voltage cable, power cables, and HVDC. - Wiki
Any current-carrying conductor, including a cable, radiates an electromagnetic field. Likewise, any conductor or cable will pick up energy from any existing electromagnetic field around it. These effects are often undesirable, in the first case amounting to unwanted transmission of energy which may adversely affect nearby equipment or other parts of the same piece of equipment; and in the second case, unwanted pickup of noise which may mask the desired signal being carried by the cable, or, if the cable is carrying power supply or control voltages, pollute them to such an extent as to cause equipment malfunction.
The first solution to these problems is to keep cable lengths in buildings short, since pick up and transmission are essentially proportional to the length of the cable. The second solution is to route cables away from trouble. Beyond this, there are particular cable designs that minimize electromagnetic pickup and transmission. Three of the principal design techniques are shielding, coaxial geometry, and twisted-pair geometry.
Whether or not Monster Cables are worth it is a war that has raged since home theater immemorial. A poster at Audioholics was put in a room with five fellow audiophiles, and a Martin Logan SL-3 speaker set at 75Db at 1000KHz playing a mix of "smooth, trio, easy listening jazz" that no one had heard before. In one corner, Monster 1000 speaker cables. In the other, four coat hangers twisted and soldered into a speaker cable.
Seven songs were played while the group was blindfolded and the cables swapped back and forth. Not only "after 5 tests, none could determine which was the Monster 1000 cable or the coat hanger wire," but no one knew a coat hanger was used in the first place.
Further, when music was played through the coat hanger wire, we were asked if what we heard sounded good to us. All agreed that what was heard sounded excellent, however, when A-B tests occurred, it was impossible to determine which sounded best the majority of the time and which wire was in use. - Gizmodo

Science Myth of the Week: 
So, there's this Japanese delicacy called Fugu. The myth is that this kind of fish is only served by professionals, because if not served correctly, the person eating it can die. Is it true?
Yes! It is a dangerous delicacy if not made correctly!
