The revolution will be all over social media

Podcast 5G: Welcome to the Revolution?

Notes:

5G involves much shorter wavelength EMW than 4G. These waves have less penetrating power and cannot travel as far, so there will be far more “towers” all over the place.

5G will be a massive increase to potential bandwidth

There’s thought that 5G can harm the migration of birds since they use the EMS from the Earth to navigate. A study in germany found that EMW can disrupt bird’s internal systems, but the waves are much longer wavelength, from AM radio, not from any cell phone. This study is usually cited by anti 5G folks but they’re not reading it correctly.

5G waves cannot penetrate human skin and thus don’t pose cancer risks to humans.

A study found that people “sensitive” to EMW found that people couldn’t tell when they were being targeted by EMW or not. The symptoms are real but they’re in people’s minds. In fact there are machines that are sold on the market that claim that millimeter EMW can cure all kinds of ailments (also false). Multiple studies have reached a similar conclusion.

Editorial: I’ve also read articles claiming that Russian accounts are deliberately spreading misinformation about 5G to try to cause a political outcry about its supposed dangers and put the US behind Russia and China in the race to develop and roll out 5G

Not Udder Bull

Podcast: Soy, Almond, Oat Milks: Are They Udder Bull?

Notes:

In terms of environmental impact, dairy milk is the worst compared to all other types.

Globally, dairy cows graze an area the size of Brazil.

On average, it takes 9 times more land to produce dairy milk compare to the others.

Almond milk requires a lot of water, and most of Americans almonds are produced in California where there’s already a lot of water pressure. It can take 4 times as much water as the other non-dairy types.

Rice milk production emits the most greenhouse gasses in the form of methane. Flooded rice paddies are filled with methane-creating bacteria. Also fertilizer runoff can be a big problem with rice.

Soy and oat milk both require more land than the other non-dairy types. Also a lot of Soy milk is grown near or in the Amazon.

There is no clear winner among the four non-dairy types. But they’re all very low impact compared to dairy.

If everyone in the world switched from dairy to soy, it would save half a billion hectares of land, a billion tons of greenhouse gases, and the same amount of water as if everyone in the world stopped having showers or baths for a year.

 

Not so fast

Podcast: Fasting Diets: What’s the Skinny?

Notes:

After not eating for a period of time your body runs out of sugars to burn and starts burning more fat for energy. An example in the episode was someone who was burning around 50% fat in normal circumstances went up to 70% after fasting.

To study how much fat is being burned they use a machine that analyzes your breath and the ratio of oxygen to carbon dioxide that you exhale. Fat that’s been burned exits the body through exhaling.

People on fasting diets tend to lose weight. A 5 week study that controlled for calories eaten seems to indicate this isn’t a result of fasting, but that people on these diets tend to eat less calories.

Studies of worms and mice indicate that fasting increases the rate at which cells consume and recycle themselves (called autophagy) and can increase longevity. Studies in humans are mixed and much less conclusive.

Studies in mice indicate that fasting can starve cancer cells (many types of cancer aggressively consume sugar for energy) and make them more susceptible to normal cancer treatments. Studies in humans for this are ongoing.

 

Just in the Sputnik of time

Podcast: The Space Race | Starting Gun

Notes: 

Werner Von Braun was a key part of the Nazi V-2 Rocket Program. Near the end of WW2 he and his team were deliberately captured by the Americans and settled in Huntsville Alabama to prevent their knowledge from going to the Soviets.

The thought was that rockets combined with atomic weapons would give the host nation an insurmountable lead in the years to come.

Von Braun’s potential degree of involvement with pretty horrific war crimes under Nazi rule was ignored and deliberately glossed over. Supposedly he just wanted to build rockets to get to space.

Because of his German background he wasn’t fully trusted by American politicians and military figures.

This led to his projects not being allowed to put a satellite into orbit, and allowed the Soviets to take the lead with Sputnik. This created a huge fear in America about ceding space to the Soviets.

Video: Life on an Eyeball Planet? It’s Possible

By: SciShow Space

Notes:

Eyeball planets are a nickname for planets that are tidally locked to their parent star., meaning the same side always faces the star. This name comes from the way the side facing the star would be a baked desert, the side facing away from the star would be a frozen wasteland, and there could be concentric circles of in between zones.

An example of a tidally locked celestial body is our own Moon.

This concept is pretty inhospitable to life, however it’s possible that a Eyeball planet orbiting a Red Dwarf, with a strong magnetic field, in the habitable zone, and with water and an atmosphere, could support life with temperatures between 50 and -50 celcius.

For these planets, life could exist in the area between the two sides. However, it would need to be able to deal with very little light, and very strong winds. Also, there would be no day/night cycle, something on which almost all life on Earth has some kind of reliance.

Video: Loneliness

By: Kurzgesagt

Notes:

46% of all Americans report feeling lonely

Loneliness can be thought of as analogous to hunger for social interaction. It’s an evolutionary product where humans who were part of social groups were much more likely to survive than those living alone.

The enlightenment and industrial revolution stressed the importance of the individual and deemphasized the importance of social groups.

In the modern world we move away from the social groups of our childhood and have more troubles forming strong bonds as adults.

Chronic loneliness is extremely unhealthy, more so than obesity or smoking.

Lord of the Rings

Video: Has Saturn Had More than One Ring System?

By: SciShow Space

Notes:

Data from Cassini shows that Saturn may be losing it’s rings at a rate of 5k to 25k kilograms per second. This phenomenon is called ring rain and at that rate the rings will be gone within a 100 million years.

It’s also theorized that perhaps the rings are less than 100 million years old. This is troublesome because many theories about how they formed require them to be much older.

It’s possible that we’re seeing a cyclical behavior where the larger planets destroy and recreate ring systems.

Even after the rings have disappeared, Saturn will still have some rings that are the result of other processes.
