How smartphone light affects your brain and body

Star Online Report

Checking your phone at night and before going to sleep seems like a normal habitual act, but it is some harmful than you think.
Smartphone screens emit bright blue light to help you see in the bright sunny morning. But at night, your brain gets confused by that light, as it mimics the brightness of the sun, reports Tech Insider.
 This causes the brain to stop producing melatonin, a hormone that gives your body the "time to sleep" cues. Because of this, smartphone light can disrupt your sleep cycle, making it harder to fall and stay asleep — and potentially causing serious health problems along the way.
Here's how it works:

'Many missing' in Myanmar landslide

Dozens of people are reportedly missing and feared dead after a landslide hit a jade mining region in Myanmar's northern Kachin state on Friday. This Reuters photo taken on November 25 shows miners search for jade stones at a mine dump at a Hpakant jade mine in Kachin state.

Dozens of people are reportedly missing and feared dead after a landslide hit a jade mining region in Myanmar's northern Kachin state.
Officials say a search for survivors and bodies is continuing after Friday's accident in the area around Hpakant.
Last month, more than 100 people were killed in the same area after a massive landslide.
Jade mining produces piles of waste rock. Itinerant workers climb the heaps to search for the gem stone.
The Bangkok Post quoted Hpakant official Tint Swe Myint as saying five bodies had already been found.
"According to witnesses, about 50 people are still missing," he said.
But Myo Htet Aung, another local official, told the AFP news agency that "just three or four people are missing at the moment" and no bodies were found at the site.
In November's disaster, many of those killed were people who made their living scavenging on or near the waste dumps left by large-scale industrial mining firms.
In a report in October, advocacy group Global Witness said the value of jade produced in 2014 alone was $31bn (£21n) - the equivalent of nearly half of Myanmar's (Burma's) GDP - yet hardly any of the money was reaching ordinary people or state coffers.
Local people in mining areas accuse the industry of a series of abuses, including poor on-site health and safety and frequent land confiscations.

Rooppur nuke plant: $12.65b deal inked with Russia

Bangladesh today signed its biggest ever contract worth $12.65 billion with a Russia’s state-run company to build the Rooppur nuclear power plant that would generate 2,400 megawatts of electricity.
The contract equivalent to Tk 1,01,200 crore is more than the total development budget of this fiscal year.
Engr Md Monirul Islam, chairman of Bangladesh Atomic Energy Commission, and Savushkin, senior vice president of Russian builder ASP, a subsidiary of Russian state nuclear power company Rosatom, inked the contract this evening at the Pan Pacific Sonargaon Hotel in Dhaka. The construction part alone involves around $11 billion.
Finance Minister AMA Muhith, Agriculture Minister Matia Chowdhury, Science and Technology Minister Yefesh Osman, prime minister’s Energy Affairs Adviser Tawfiq-e-Elahi Chowdhury and State Minister for Foreign Affairs Shahriar Alam, among others, were present. 
Of the $12.65 billion, the Russian government would provide 90 percent ($12 billion) as loan.
During loan negotiations, Russia argued that the cost was not high and that compared to nuclear power plants built by Rosatom in other countries, Rooppur would be cheap.
Earlier this month, the government initialled the financial contract with Russia. This was expected to be done some time next year.
Nuclear plants demand high upfront cost. But as its fuel cost is comparatively low and plant life is very high, power tariff turns out to be very cheap.
The economic life of the plant has been estimated to be 50 years. However, Rosatom says the Rooppur power plant would last for 60 years, three times higher than conventional coal or gas powered plants.
The exact power tariff would be available after the construction agreement is signed.
Earlier on Wednesday, two government committees -- the cabinet committee on economic affairs and the cabinet committee on purchase -- approved the proposal for general contract signing with Rosatom.
Following the approval, Minister for Science and Technology Yefesh Osman said “It is beyond just electricity, it's the technology. It will take Bangladesh to a new height.”
He said the prime minister was keen on seeing at least one of the two units, each with 1,200MW capacity, to go into operation within 2021.
However, it takes about seven years to build such a plant, he said.
Russia had said it might be able to meet that deadline for one unit, if the government signed the construction agreement within this month. 
Russia has agreed to take care of the fuel. It would bring in fuel and take back the spent fuel to Russia.
“I believe $12.65 billion is a good bargain. Besides, our prime minister believes that once this project takes off, we will learn a great deal about the technology,” said Yefesh Osman.
According to the proposal of the Ministry of Science and Technology, the interest rate on the loan is 6 months' LIBOR (London Interbank Offered Rate, an average of interest rates estimated by each of the leading banks in London) plus 1.75 percent.
However, the interest rate cannot be more than 4 percent per annum.
The proposal said as per the existing LIBOR, the interest rate might be 2.55 percent.
The utilisation period has been estimated at seven years and the repayment period 28 years, including 10 years' grace period.
The commitment fee is 0.5 percent.
Finance Minister AMA Muhith in October told reporters that the loan was neither concessional nor commercial.
In the case of commercial loans from the Asian Development Bank (ADB), Bangladesh normally pays service charge of around 4 percent, with repayment period of 20 years.
The interest rate on commercial loans from the World Bank, ADB and JICA is below one percent and the repayment period is 30 years to 50 years, including grace period.
The general contract approved yesterday has eight main components --detailed design, equipment supply, construction and erection, commissioning & testing, warranty operation, initial nuclear fuel supply, equipment transportation up to construction site, and service up to warranty operation.
Rosatom is keen on signing the construction contract first since it takes a long time to install equipment for a nuclear power plant, Muhith said.
According to the proposal, the provisional takeover of the first unit is expected to be in October, 2023, and the second one in October, 2024. The final takeover would be in October, 2024, and October, 2025, respectively.
Preparatory work to build the plant was underway under a $500 million technical assistance from Russia.
In June, Rosatom submitted a feasibility report on the plant to Bangladesh Atomic Energy Commission.
Rosatom would maintain the plant for the first year of its commercial operation before handing it over to Bangladesh authorities.
