Fig 01- Snow in the jogging track area

Hundred millions people across America have experienced “deadly” snow storm. Temperature below zero Celsius degree during second week of February 2021.

Almost all southern states to brace more icy and frigid temperature than normal February each year, the states include:

- Texas

- Louisiana

- Mississippi

- Alabama.

Our city, Baton Rouge, temperature reached -8 C (18 F) degree. This is our first time experienced to face lower temperature in the Southern state.

The storm caused several problems in our neighborhood and city:

- power outage

- no water supply

- roads block

- grocery stores are closed

Fig 02- Ice on all branches of tree

Many our neighbors have no electricity more than 50 hours since Monday, 15 February 2021.

Fig 03- Branches fall down on the street.

No signs of light until Wednesday afternoon, 17 February 2021. We don’t know until when.

Few neighbors had to leave because it was too cold inside and they don’t have a fire place inside their houses.

Since our neighborhoods have different grids, we and several neighbors are lucky to have light and water supply during snow storms and until today.

How about with your cities? Have your cities snow storm?

Kit Kat Chocolates for Valentine’s day, just illustration

We have at least 3 new dangerous variants of Sars Cov 2 viruses (Covid 19) so far:

- UK variant, identified as B.1.1.7

- South Africa variant, called as 20H/501Y.V2 or B.1.351

- Brazil variant, known as P.2

As reported by BBC News (February 9, 2021), the scary facts that South Africa halted the employing of UK’s AstraZeneca – Oxford vaccine, because the vaccine didn’t effective against new virus variant (20H/501Y.V2 or B.1.351).

I have posted about AstraZeneca – Oxford vaccine compared to other two American vaccines, Pfizer – Biontech and Moderna vaccines. Please find at:

Is AstraZeneca Covid 19 Vaccine Suitable for Poor Countries? - Virus 31

The good news that another American vaccine, Johnson & Johnson has “good” efficacy to contain South Africa variant with one shot only, after proved by clinical trials.

Effective rate of Johnson & Johnson single shot vaccine in 3 important places (regions):

- 72% in the USA.

- 66% in Latin America, include Brazil

- 57% in South Africa

Hence, a Johnson & Johnson single shot vaccine is “estimated” able to give protection against Covid 19 virus and its new variants.

Plants in front a house, just for illustration

Men’s fertility mainly relates to sperm accounts, sperm movement and semen quality (Mayo Clinic, 2021).

It is believed the male fertility is decreasing globally due to many causes, include:

- exposure to pesticides

- obesity

- smoking

- stress

- exposure to chemical substances

- certain infections and illness

- lifestyle factors

Then, the question: May Covid 19 Reduce Men’s Fertility?


Based on study published in the Journal Reproduction, then reported by CNN on January 29, 2021

One of corner in the city garden

People who infected by Sars Cov 2 virus (corona virus) may affect on their fertility.

Based on primary observation to groups of fertile men with and without corona virus infections, then, the result shows that virus lead to impair of:

- sperm quality

- semen quality

The more serious infections, the lower sperm quality, thus higher possibility to reduce men fertility.

Even this is early observations, the findings make researchers to concern.

Take care!!  

Chocolate Covered Strawberry from Neighborhood – Food Variety 9

Wednesday, January 27, 2021

Fig 01- Strawberries covered by chocolate decorations

From internet searches, the prices of Chocolate Covered Strawberries are very varies. No price below US$ 1 each.

The most common prices range from US$ 15 to US$ 25 per a half dozen (6 pieces). Quite expensive for me.

Our neighborhood sells Chocolate Covered Strawberries with little bit lower than market prices, but still expensive for me:

- a half dozen (6 pieces) for $12; and a dozen (12 pieces) for $24

- a half dozen (6 pieces) for $15 infused with alcohol; a dozen (12 pieces) for $30 infused with alcohol.

I wonder, why are Chocolate Covered Strawberries so expensive?

The reasons might relate to:

- public perception as a “luxury” goods.

- highly demand

- chocolate is shorten life, thus, must be removed from store shelves quicker.

Fig 02- Chocolate covered three strawberries

Chocolates are good to keep them in the refrigerator, but it is no problem for 10 hours at room temperature.

Fig 03- several designs of chocolate covered strawberries.

In addition to strawberries, other fruits are suitable as well to be covered by chocolates.

Slices of some fruits which could be covered by chocolates:

- figs

- pears

- banana

- mango

- any other sweet fruits.

Have you tasted chocolate covered strawberry or any other fruit? What do you think?

Why is Cat Vomiting Frequently? - Gardening and Hobby 18

Friday, January 22, 2021

A cat in front door, just illustration

As a cat owners, we experienced with our cats vomiting, but we may wonder: why do they vomiting frequently?

There are many issues relate to cat vomited, some of them are:

- eating a houseplant

- ingesting a toy piece

- hairball in the stomach

- allergy and sensitive to certain foods

- undigested foods, because of quickly consuming.

It is said that vomit is normal for cat. However, it is not normal if cat changes their behavior and has vomited very often.

We may judge the level of “the seriousness” of vomit is based on its content and colors:

- yellow and foamy lead to hairballs

- thick yellow bile mean that there is serious health problems such as kidney and infection. 

A cat plays outdoor

We should find medical help immediately, if our cats have frequently yellow vomits and shown the following behaviors:

- suddenly loss or increase appetites

- lethargy

- unusual behaviors.

- show discomfort.

What do you do if your cats have shown vomiting frequently?

Virulence of Covid 19 Variants in Japan – Virus 35

Sunday, January 17, 2021

Pretty Bougain villae bonsai

When I am writing this post, there are very said facts about Covid 19 in the world and other countries. 93.8 million cases, and 2.01 million deaths in the world

Top 5 countries with cases and deaths (from several sources as of January 16, 2021) are following:

- 23.6 million cases, and 393,000 deaths in the USA

- 10.5 million cases, and 152,000 deaths in India

- 8.39 million cases, and 208,000 deaths in Brazil

- 3.84 million cases, and 63,558 deaths in Russia

- 3.32 million cases, and 87,295 deaths in UK

However, the threaten of new variant of Covid 19 virus creates the condition even worst while inoculation of vaccines just start in many places.

First, the UK’s variant, then South Africa, and lately was from Japan. The question then :

How dangerous those new variants?  

Red chili from backyard

What we know about UK and South Africa Covid 19 variants until now:

- much more dangerous than original strains

- more transmissible

- mutations occurred to “spike protein”

What we know about Japan Covid 19 variants until today:

- Japan strain comes from Brazil

- higher infectiousness

- mutations not only to spike protein, but also on the variant ability to evade of our immune system memory.

Good news that the Biontech-Pfizer vaccine ables to fight effectively the UK and South Africa Covid 19 (Sars Cov 2) variants.

However, studies are underway to observe whether any vaccines will work to fight virus variants in Japan.

If not, we might need to upgrade our current vaccines. Hope, we will know soon.

We faced with devastating pandemic during 2020, and even until today. Vaccine roll out, might end this pandemic soon.

Unfortunately, America experienced 30 months outbreak of virus called as Hepatitis A virus (HAV) before this recently pandemic.

The infection started from March 2017, and end at August 2019 which caused 244 deaths of 24,952 cases in 30 states.

The virus infects liver, the very important organ. Then lead to liver inflammation or damage, to disturb organ functions as:

- to process nutrients

- to filter the blood

Hepatitis A virus is very contagious. The World Health Organization (WHO) said that about 7 thousand people dead per year worldwide due Hepatitis A.

In addition to virus, liver damage may be caused by some factors such as:

Mini Sago Palm at the Corner - Gardening and Hobby 17

Monday, January 4, 2021

Mini Sago palm, sweet at the corner

I know the word “sago,” its tree could reach 50 feet (15 m) in height after 15 years old.

The species of Metroxylon sagu produces starch called as “sago” or “sagu” starch.

Other two species of palm trees produce sago starch are:

- Arenga spp.

- Maurilia spp

One sago tree could produce 90 to 180 kg starch. The starch is used generally as:

- foodstuffs such as noodle

- textile sizing

- adhesives

The trees are found in freshwater swamp areas of South East Asia and Papua New Guinea. 

Fruit from mini sago palm

Here in America, we have another type of sago, mini sago palm with scientific name Cycas revoluta.

The plant native to Asian regions, include southern Japan. Since its small size, it is popular as one of ornamental plants.

We have grown the sago in the corner of our house, some people do grow its as an indoor plant.

Several advantages of sago plants:

- easy to take care

- grow well outside and indoors

- free of pests

- available in most nurseries.

- may be grown in pot

Mini sago plants grow slowly, and they reaches about 15 feet (5 m) tall after several years. This is another reason why people chose sago plant to put in their garden.
