This page contains "20th June 2018" current affairs analysis from different newspapers and magazines like the hindu, indian express, PIB and yojna.
Quality and relevance are two key features considered while writing the content, all the topics are based on the pattern of previously asked questions in exams like UPSC CSE, IAS, State PCS, SSC, Banks PO and like wise competitive exams.
1) Database on unorganised workers
Centre has decided to create a national database and Aadhaar-seeded identification number system to facilitate welfare delivery to 40 crore workers in unorganised sector after 10 years of passing "The Unorganised Workers Social Security Act, 2008".
The Unorganised Workers Social Security Act, 2008, had first mandated that every worker be registered and issued a smart ID card.
Government has issued a tender in this regard, a "single unified sanitised database" will include details of both nuclear and extended families of unorganised workers.
The platform will be developed and managed by centre with the help of service providers; while identification and registration of workers will be done by state government.
The platform, and other worker databases will use Socio-Economic and Caste Census 2011 as the base from states and other Central ministries such as Textiles and Health.
The identification of workers will be done using Aadhaar information. In areas where Aadhaar is not yet available; other valid i cards will be used with an option to link aadhar later.

2) Oldeset Sumatran orangutan died
Why in news ?
The world?s oldest known Sumatran orangutan has died in an Australian zoo aged 62, leaving behind 54 descendants.
Sumatran orangutan
The Sumatran orangutan (Pongo abelii) is one of the three species of orangutans. Found only in the north of the Indonesian island of Sumatra, it is rarer than the Bornean orangutan but more common than the recently identified Tapanuli orangutan, also of Sumatra.
Sumatran orangutan is a critically endangered species and can reach upto 40-50 years of age in wild.
According to the WWF, there are only about 14,600 Sumatran orangutans.
3) Cardiovascular disease trend : National survey
According to survey conducted by Public Health Foundation of India, people from Kerala including both men and women are at highest risk of Cardiovascular disease, while people from Jharkhand are at lowest risk.
Gender wise men from Himachalpradesh and Nagaland while women from Goa are at high risk of the desease.
Adults in urban areas, as well as those with a higher household wealth, tended to have a greater cardiovascular risk; while people living in rural areas are at low risk.
In poorer households and rural areas smoking was more prevalent, while in wealthy households and urban areas risk arises from high BMI, high blood glucose and high systolic blood pressure.
Cardiovascular diseases describe heart conditions that include diseased vessels, structural problems and blood clots.
4) New photosynthesis process
Till now botanists and plant biologists believed that; white light ( 680 to 700 nm) and chlorophyll are needed for photosynthesis. While according to a new study it is believed that certain bacteria don't need white light, and instead use far-red light (~ 750 nm) for photosynthesis.
The wavelength of visible light or white light is 400-700 nm, it was believed that all plants uses red light ( 680 to 700 nm) for oxygenic photosynthesis.
The research also finds that, when cyanobacteria (a different kind of chlorophyll) was grown in near- infrared light, chlorophyll a shuts down and a special chlorophyll, chlorophyll-f, performs the same task.
Chlorophyll-f, which was long believed to be a helper in harvesting light, has now been found to play an important role in photosynthesis in shaded environments.
