Thursday, August 13, 2020

 Pretty orange Canna flowers


I saw Canna flowers have many colors in my city garden, some of them:

- blood red or bright red

- pale yellow

- bright yellow

- orange

- red

- combinations of pink, salmon and apricot


Canna usually blooming in the Summer until Fall. It is reasonable why this flower growing well under full sun and moisture conditions.


We can see Canna bloom for many times in a year, depend on weather conditions. Fading flowers might be replaced by new ones, thus stalks live two seasons long.


Since flowers look bold, and one of flamboyant summer, it is good to have the Canna in our garden.


Flowers of Canna look bold and beautiful.


It is said to grow and care Canna is easy, from bulb to produce bright and pretty flowers.


This flower is found in the North and South America. The flower abundant in some parts of:

- Argentine

- South Carolina

- Florida

- Caribbean Islands


Petal of Canna flowers


In some developing countries, in addition as a gift for certain special days such as father’s day, this plant also used as a source of foods.


We find starch, called as achira in the bulb and rhizomes of Canna plant. The starch be processed as noodles. A very high quality noodle.


Have you seen Canna flowers? What color do you like?

Tame Ducks are Walking on City Lake Sides

Tuesday, August 11, 2020

 Fig-1. Three young ducks


We found many ducks, especially young ones play around at the one side of city lake peacefully, no predators and no hunters for sure.


In the wild nature, these ducks live in the quite variety areas, include in the:

- coastal marshes

- bays and bayous

- beaver ponds

- rice fields

- flooding parts of woodland or forest


At least, there are 3 common ducks living in the nature of Louisiana:


1) Mallard

The males are characterized by green heads as you may see two ducks at above photo (Fig-1). Actually, Mallard is migratory ducks, millions from North to South in Mississippi rivers during winters.


Fig-2. Two ducks, male and female


2) Mottled

Bills of Mottled is yellow for male, while olive green for female. The ducks are non migratory, usually stay in coastal marshes all seasons.


Fig-3. Male of Mallard duck.


3) Wood ducks

The habitat of these ducks is in the swamp areas of forests. Since timbers have been harvested almost completely, the ducks may be found in many places include in the Mississippi rivers. 


Fig-4. Lonely duck


Interestingly, ducks watching and hunting are part of important activities in many parts of America. About 11.6 million ducks are harvested per year in the USA.


Some best states to watch and hunt ducks are:

- Louisiana

- Mississippi

- Nebraska

- Minnesota

- North Dakota


Have you watch or hunt duck in nature? Where? Did you taste duck meat?

What is mRNA Covid-19 Vaccine? - Virus 15

Friday, August 7, 2020

                                                         Painting at my neighborhood

As we might know that messenger ribonucleuc acid (mRNA) play crucial role to supply information to DNA in protein synthesis to regulate cells and tissues in our body.


Unfortunately, virus, in this case Covid-19 “manipulate” RNA to enable to enter cells, then duplicate itself. Consequence of this activity:

- infected people to be sick or dead

- if virus infected lung, then patient to be difficult to breath.


Vaccine is one of effective methods to control virus. Traditionally, vaccine was made by weaken or killed virus, then injected into body to stimulate immune system to produce antibody.


The traditional method has taken long time (could be years and even a decade) to develop, because of:

- make sure that weaken or dead virus be able to stimulate immune system to produce antibody

- we must certain that virus is dead or weak, not strong enough to infect human.

- search suitable media for virus to well growing

- need large scale to test effectiveness and safety of vaccine.


In 1990, scientist develop mRNA vaccine which contain viral protein. This viral protein could trick immune system to “think” that body is attacked by real virus. Then, immune system responses by producing antibody to fight virus.


In case of Covid-19, the technique is quite advance where:

- additional certain substance into mRNA to reduce negative effects of vaccine such as inflammation.


- using spike protein, a kind of protein for virus to enter cells. Thus, antibody result from vaccine to be effective to combat Covid-19.


The mRNA vaccine shown good result in first and second clinical trials, hope, will be the best result in the final trial.

Have you Seen Black Racer Snake Comes in your Backyard?

Saturday, August 1, 2020
A black racer snake in the backyard.

First, we saw skin of snake on our backyard sometimes ago. Its could be Black racer snake, because this snake is a common reptile in the southern USA.

Coluber constrictor is scientific name for black racer. It is said the snake is active during daylight, and not poisonous.

Few other characters of black racer are:
- fast moving snake (why called as racer)
- length could reach to 55 inches (140 cm)
- color blind
- yearly to shed its skin
- live in woody, garden or yard areas
- predators of snake are hawk and bigger birds.
- similar appearance to venomous snake called water moccasin.


Black racer in other position


We might wonder about what kind of food Black racer eat. Here some:
- mole
- bird
- lizard
- frogs
- rodents
- insect
- smaller snakes

We never saw snake’s eggs in our yards. Some sources said the snakes could have about 20 eggs yearly with 40% survival rate for young born.

In fact, black racer snakes have positive impact on yards, because they may eat or get rid of the animals which cause damaging to the plants in the garden or yards.

However, in case you do not like this snake to stay in your yard, the best way that you snatch this reptile by trap.

Have you seen any snakes in your gardens or backyards? If so, what do you do?

What is Safe Dosage of Covid-19 Vaccines? – Virus 14

The good news that we are in phase 3 clinical trials with 30,000 volunteer at 89 different site in the USA now.

We might have questions:
- is safe for human?
- what is safe dosage of Covid-19 vaccines?

Yes, vaccine, in this case, developed by cooperation between federal agency and biotechnology company, National Institutes of Health's National Institute of Allergy and Infectious Diseases (NIH) and Moderna is safe.

It is reported safe because it had been went through two clinical phases, and will complete final phases with thousand volunteer soon.

There are 3 dosages are tested so far:
- 25 micro gram (µg)
- 100 µg
- 250 µg

The results shown that all 3 dosages have positive impacted where its generated immune responses. No serious effects have been recorded.

The phase 3 will involve dose of 100 µg, it is medium doses. Researchers use this medium dose, because:
- at first shot, there is little reaction.
- after 1 month, there is moderate reaction at second shot.

In case of 25 µg dosage, the reaction is mild. There is severe reaction when using 250 µg dosage.

We are waiting the best outcome from clinical trials of 300,000 volunteer as soon as possible, probably by next 3 months!
