Polar Lights In North US

The beauty of the northern lights is not limited to the earth poles. There are areas in the upper Midwest where you can also see the Northern lights.

The cause of this is that the Earth's magnetic field is weakest around the poles. It is known as the auroral oval. Along the curved edges, charged particles released by solar flares enter Earth's atmosphere and create a magnificent nighttime spectacle, colliding with oxygen and nitrogen, generating a breathtaking sight.

Although the aurora magic occurs far to the north, on some occasions, the auroral oval occurs as far south as Cleveland and Chicago.

The darkness is also the secret. The night lights around the new moon are better than the bright lights of the full moon. Although, this depends on the solar and magnetic activity of the Earth.

From northern Minnesota to the Upper Michigan Peninsula and beyond, up to 200 auroral episodes can be seen each year, weather permitting.

The possibility of seeing the lights in the sky increases as you travel north, towards the pole. Therefore, the places to enjoy the aurora in the USA are close to the border with Canada. 

These places include the Panhandle National Forest in Idaho, the National Wildlife Refuge in Maine, Cook County in Minnesota, the Upper Peninsula of Michigan, Mount Washington Valley in New Hampshire; The ethereal episodes of auroras frequently occur during winter when it is cold. Many parts of Alaska are visible due to its polar nature.

If you want to get a good shot of these auroras, I recommend you look for the occurrence of a geomagnetic storm; with them, the chances of seeing an aurora increase a huge. Additionally, these storms are periods of giant solar discharges that hit the Earth's magnetic field and cause more diverse and powerful auroras.

The displays of auroras are happening in the USA due to the displacement of the auroral oval, which encompasses various northern lands. In addition, the occurrence is typical when the Earth is right in the path of a high-speed solar wind current, which causes it a greater area of ​​coverage across the entire oval.

The shifting of the Earth's rotating and magnetic poles can cause the polar zones to shift to different areas in the region, which means that auroras may appear in unexpected places in the future.

Blue Zones, The Longest-lived People

Image
There are places where the longest living populations on earth coexist; remote, small, close to the ocean.  Okinawa, Japan; Sardinia, Italy; Nicoya, Costa Rica; Ikaria, Greece and Loma Linda, California. They are the world regions where people have low rates of chronic disease and live longer than anywhere else. These regions have the highest number of people surviving more than 100 years. Image 1: The blue areas are regions with the highest number of centenarians. These places are called "blue zones." Categorized as the healthiest areas in the world, according to historical and solid scientific evidence. The healthy habits of these communities have managed to pass this offspring to their children with healthily predisposed genetic codes. However, genetics probably only account for 20-30% of longevity. Environmental influences, including diet and lifestyle, determine the remaining percentage of people's health. More than 90% is a diet based on plants, vegetables, legumes,...

¿Vegan Vaccines?

Image
With today's new technologies to combat the pandemic, vaccines have given rise to another current controversy that has arisen over their manufacture and the involvement of animals. COVID-19 vaccines have the claim to contain no eggs or animal products, according to the UK's National Health Service (NHS). Pfizer, Moderna, and Janssen have declared that their vaccines are free of animal-derived ingredients. Image 1: Monkeys are animals enormously relevant for traditional vaccine development. Although the vaccine does not contain ingredients of animal origin, many animals perish in the developing process of the vaccine. To ensure proper use in humans; until the government approves the release to the market. Animals serve as the system for checking medical studies and not harming humans in the drug development process. Consequently, 3 out of 10 or more animals do not survive the tests; they die from the damage caused by the drugs; those that survive are euthanized, which means that...
