Late in 2018, a bill was passed in Japan to widen the entry of immigrant workers. The bill was to mitigate severe shortage of labor amidst an aging population and falling birth-rates. Prime Minister Shinzo Abe described the bill as a much-needed reform to ensure the smooth functioning of Japanese  economy. The bill makes it easier for immigrants to work for longer duration in Japan.

More than 20% of Japan’s population is over 65 years old which is the highest proportion in the world. It is projected that by 2030, one in every three people will be above 65 years or older and one in every five will be 75 years or older.

The fertility rate has fallen to 1.4 children per woman in Japan which has been attributed to a host of factors including changing lifestyles, people marrying late, not marrying at all, and the economic insecurity of the younger generation. It is projected that by 2050, Japan’s population will decline by twenty million while the world population is expected to increase by two billion.

Japan has traditionally been quite homogenous with  very little diversity to show. This trend now appears to be changing as today nearly three million migrants live in Japan which is three times more than the figures of 1990. As the country struggles with a rapidly aging population and severely declining domestic labor, the number in all likelihood is only going to increase.

Conservative Prime Minister Shinzo Abe based his support for the reforms in immigration policy on demographic arguments.The conservative section of the parliament has been a staunch supporter but the left opposition has been critical of the bill citing concerns about a lack of regulation on the employers which could lead to over-exploitation of the workers. Prime Minister Shinzo Abe’s government promised to set up a hundred consultation centers nationwide for dealing with issues related to workplace abuse specifically for the migrant workers.

However, that’s as far as those resisting the bill have gone. Nationalist and xenophobic voices protesting the bill have failed to gather steam. In fact, according to a survey by Nikkei in January 2020, almost 70 percent of Japanese said it is “good” to see more foreigners in the country.

Japan’s aging population has made it difficult to find the workers and some companies have more than 120 job openings for every 100 job seekers nationwide. Quite evidently, immigration now appears to be the most feasible solution for Japan- a country that has traditionally been restrictive with its borders when it comes to ethnic diversity.

Discovery of a new particle: A Charming Tetraquark

While the world is horrified by the novel Coronavirus, scientists at the European Centre for Nuclear Research (CERN) announced the discovery of a never seen before tetraquark. Any finding in particle physics is a phenomenal one because it could tell us a lot about the origins of the universe and how everything came to be. And this discovery is quite charming and quarky (quirky).

Quarks are the elementary particles so any further division of these particles is not possible. This means everything in the universe is ultimately a combination of Quarks. Any new discovery of Quarks  therefore increase our understanding about the origin of universe

When three Quarks come together, they form familiar particles known as Baryons, for instance, protons and neutrons, found in the nucleus of an atom. A tetraquark, in particle physics, is an exotic meson composed of four quarks.

Murray Gell-Mann, recipient of the 1969 Nobel Prize in Physics for his work on the theory of Elementary particles, chose the name ‘Quark’. Another scientist,  George Zweig from CERN also proposed the Quark theory independently of Gell-Mann.

All the new particles are detected using particle accelerators where particles are accelerated at almost the speed of light and collide to look into their subsets. It is like knocking two rocks together so that they break into smaller constituents.

The most recent tetraquark, named X (6900) was discovered by CERN physicists while working on LHCb (Large Hadron Collider beauty experiment). The already known tetraquarks contain a particular combination of two relatively heavy quarks and two light Quarks. On the other hand X(6900) consists of four heavy Quarks: two Quarks and two anti-Quarks.

This exclusive particle made of unusual combinations is a perfect setting for understanding the fundamental force of nature known as Strong Interaction. The strong force is vital to comprehend as it binds together protons, neutrons and the nucleus that ultimately make up matter. Another perk of X(6900)  is its relatively heavy mass, so these are simpler to look at and are more stable as compared to notoriously fast moving-lighter ones.

The paper written by 800 scientists is yet to be peer-reviewed. The bump observed has a statistical significance of more than five sigma (standard deviations) that is good enough to claim the discovery of a new particle.

In any scenario, this unusual discovery will serve as a piece for completing the puzzle of our universe while serving as evidence of the presence of new particles not yet found.
