Corn Price Increases Sharply in the Market - Economics 15

Fig 01- Corn with husk in the market.

During this time around, we understand that the corn price is lower. We bought corns with price of US$1 for 10 counts last year.

Surprisingly, we bought 10 counts of corn with price US$6.60 in the grocery recently, 6 times expensive than last year.

What happen?

Why?

We try to find out through internet. The answer that corn price is soaring, the highest since 8 years ago.

Dry weather and cold temperature caused lower and delay production, especially in the countries such as:

- Brazil
- USA

On the other side, demands are increasing, followed by opening economy everywhere is believed to drive corn price.

Who are gaining?

Sure, the gainers are farmers, especially American farmers, since they can sell their corn in domestic and foreign markets.

Moreover, corns are used (processed) in the forms of many products, few of them:

- foods for livestock
- sweeteners
- corn oil
- beverage
- fuel ethanol
- starch

What are corn products favorites to you? 

Why?

Why don’t We Have HIV Vaccine yet? - Health and Medicine 22

Fig 01- Tulip as illustration

Human Immunodeficiency Virus (HIV) has been identified by Luc Montagnier and his team from Pasteur Institute, France in 1983.

It is mean that HIV has been known “formally” very long time ago, yet, we have no vaccine so far.

Yes, we have HIV’s drugs in the market, but to “suppress” virus amount in the blood only.

Drugs are prescribed to maintain the virus load at lower level, and hope:

- no transmission of virus to others, especially sex partners
- immune system has opportunity to rebuild itself.
- HIV free babies from infected mothers

Unfortunately, as reported by Our World in Data (2014, and revised in 2019) that almost 1 million people died per year caused by HIV/AIDS worldwide. The death mainly in the very developing countries.

The question then, Why don’t We have vaccine yet to combat HIV/AIDS diseases?

Two main reasons why don’t We have vaccine yet to combat HIV/AIDS diseases:

- scientific or knowledge
- economics (funding)

Molecules on HIV surface look like to protein in healthy people, hence, our immune system difficult to recognize its.

This is a kind of “deception” which make virus has advantage to infect cells in patient’s body, then destroy immune system.

This is the main reason why vaccine inventors can’t develop HIV vaccine until recently.

In respect to economics, no “big money” yet to develop HIV vaccines compared to Covid 19 vaccines, just for example.

Hope, these hurdles could be solved in near future!
