Mars had the right stuff for life, scientists find

Clays, sulfates and other minerals that are all key to life were found in the powdered samples of Mars. The water that once flowed through the area, known as Yellowknife Bay, was likely drinkable. Scientists speculated that Mars should have at one time at least had organic compounds delivered to its surface by organic-rich comets and asteroids. They also claimed that there might be different types of organisms such as chemoautotroph. Scientists studies comparing the environment of Earth and Mars.

We can see Mars in the sky easily, so it is quite surprising to me that research showed possibility of existence of  organisms with concrete evidences. There have been so many articles that tell us Mars or Moon might have organisms in old times or now. I also think there might be organisms like human somewhere in cosmos. But I don't believe it is Mars, because it has too high pressure and temperature to live. There isn't enough oxygen which is base element of living as well.

WHO confirms 15th case of deadly new virus in Saudi Arabia

Recently, a Saudi man infected new deadly virus has died. Nine of the 15 people confirmed to have been infected with this virus have died. The virus called NcoV causes common colds but similar to SARS. Symptoms of NcoV include serious respiratory illness, fever, and coughing. Scientists found that NcoV is well adapted to infecting humans and may be able to use medicines similar to drug for SARS.

I can't remember how serious the damage of SARS as I was young, but I know that it was tremendous. Also, the novel influenza prevailed throughout the country few years ago. Like this, new viruses or new diseases are springing up and threatening human beings. I just hope that scientists deal with viruses quickly.

Strong signs Higgs boson has been found: CERN

Physicists believe that the boson and its energy field were essential in the beginning of the universe after Big Bang. The particle and the field called Higgs who predicted their existence 50 years ago, are the last major missing elements for Standard Model of cosmos. It was spotted last summer, but held back from the saying what it was. It remains a question whether this is the Higgs boson of the Standard Model up to this day. Scientists also has done a lot of experiments using subterranean collider, particle accelerator etc.

Discovery of the faster-than-light particle called neutrino astonished the world 2 years ago. However, it was proved to be an experimental error. This time, it is the Higgs boson! Development of the science appears to my eyes! I hope that physics is approaching completion, because I don't want to learn and memorize more physical facts.

Dominican Republic wins World Baseball Classic

Dominican Republic won World Baseball Classic(WBC). It won, three to nothing. Robinson Cano who hit .469 with two home runs was named MVP of the tournament. Rain started falling in the middle of the game, so there was a small disturbance. Puerto Rico which got second place also played well but its vigor wasn't inferior to Dominican Republic.

Korea also entered the game but they were eliminated in the first round of competition. I expected Korea's championship cup, but players' concentration made me disappointed. It was an immense surprise to me that Dominican Republic won WBC because I didn't know that it is a baseball power, even the existence of that country. I hope that Korea will won the next competition.

South Korea network hack prompts broadcast, bank outages

YTN, MBC and KBS, Korean major broadcasting networks were hacked by an unknown organizations calling itself "Whois Team as.well as Shinhan Bank and NongHyup Bank. Government and police officials speculate that it would be a deed of North Korea. Because it intimidated to attack the United States and South Korea few days ago. This incident was quite critical, therefore insiders said that it would take a few days to gather evidence.

Some of my friends using NongHyup or Shinhan Bank told me that they couldn't withdraw money from ATM. I didn't know what happened before I read this article. I also think North Korea would be a criminal of this attack, because it has had problems-DDOS attack-like this before. Groups, especially financial groups might get a tremendous loss. I hope that authorities will cope with hacking quickly and find culprits.
