Rose breasted grosbeak Comes to Our Neighborhood – Nature 23

This migration bird visit our neighborhood rarely, even some neighbors never seen it for long time.

Luckily, we have seen Rose breasted grosbeak in late spring of this year. The birds visited some neighbor’s feeders.

The birds live and breed during spring and summer seasons in many American states and even in Canada.

In the fall and winter, then, Rose breasted grosbeak return to the south in the countries or regions such as:

- Mexico
- Central America
- South America
- and the Caribbean

We believe, Rose breasted grosbeaks migrate from Mexico, then go up to the North America and Canada.

Some of them stop by in our state then breeding. This bird love to breed in areas such as:

- woodlands
- forest edges
- and in the parks

Our neighborhoods have less trees in recent years, hence its might be reason why this bird not seen quite a while.

Differences of Shale Oil, Crude Oil and Fracking – Science 12

I wonder when listening about “fracking” during US presidential campaigns in 2020.

Then, I tried to find out what fracking is.

Image 1- Location of Shale Oil and Crude Oil
(credit to Petroleum Management)

Fracking is the method to drill oil and gas by using high pressure to make fracture in the shale formations.

Shale formation is below surface, could be near to more than one thousand feet (300 meter more).

Layer thickness may from few meters to hundred meters, then, from here the shale oil is extracted.

Image 2 – Wild flowers under tree

Two effect of fracking technique, bad and good sides.

1) Bad sides if lack of safety rules:

- poison groundwater and surface water
- disturb wildlife

Image 3- Mold on the leaves

2) Good effects:

- could replace coal for energy sources, hence decrease air pollution.
- increase energy security

Moreover, as you might know that conventional or crude oil is closer to surface (please see image 1).

In term of cost production, crude oil is cheaper than shale oil. As mentioned by Investopedia (2022), the cost comparison is following:

1) crude oil cost between US$ 20 to US$ 31, and even lower US$ 10 per barrel in Saudi Arabia.

2) Shale oil cost between US$ 46 to US$ 58 per barrel.

Despite of the late onset Alzheimer's dementia causes are still unknown, but the scientists tend to say that it could be by a combination of:

- lifestyle
- environmental
- and genetic.

The specific genes that directly cause the late onset Alzheimer's disease is from Chromosome 19 (Please see Image 1).

Image 3- Red flower, just illustration

The genetic marker of Alzheimer's disease on chromosome 19 is APOE. The mutation in this chromosome cause increases Apolipoprotein E (APOE) that plays a big role in memory ability in aging.

For the early onset Alzheimer's disease comes about a person between thirties and mid-sixties is caused by genetic mutation.

The mutation was in the any one of number of different of single gene in any chromosome with number 1, 14, and 21.

In my opinion, this is one of interesting parts to understand Alzheimer's disease.

Isn’t it?
