The Shark that glows in the deep,dark sea

Kitefin Shark

The world is full of mysterious and interesting creatures and this year is proving especially lucky for scientists to identify unique organisms. In February, a rodent named Springshare was identified, which glows pink and orange in ultraviolet rays. Living in the savannah forests of East Africa, this organism produces this color with the help of the porphyrin pigments present in its hair.

Recently, the world’s largest luminous vertebrate has been identified near New Zealand. This blue glowing creature is a kitefin shark (Biological name- Dalatias licha), which can grow to be around six feet tall. It shows the property of bioluminescence. Scientists have published an article about it in the Frontier Marine Science Journal, however they have not yet found what process it uses to shut off or turn on its luminescence.

Bioluminescence is the production and emission of light by a living organism. It is a form of chemi-luminescence i.e. using chemical substances to produce light. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria, and terrestrial arthropods such as fireflies.

Scientists at the Catholic University of Belgium conducted a sea search expedition to identify kitefin sharks. According to Jerome Melfet, he was successful in taking a picture of a living shark. Their samples were also taken to research about the science behind the bioluminescence the shark shows.

According to scientists, bioluminescence is advantageous to this creature as this glow is meant to dodge big enemies. The blue glow of these sharks helps them to camouflage in the blue light coming from the sky and hide to avoid becoming the food of bigger fishes.

The hormone that helps us sleep makes the shark glow. This glow is not caused by hormones, but from their brain or nervous system. This hormone is melatonin, which helps us sleep, but gives shine to the sharks. However, it is not very clear whether these hormones have anything to do with the brightness of the shark.

PM Modi to inaugurate ‘Maitri Setu’ connecting India and Bangladesh today

Prime Minister Narendra Modi will inaugurate Maitri Setu between India and Bangladesh today through video conferencing. Mr Modi will also inaugurate and lay the foundation stone of multiple infrastructure projects in Tripura during the event.

The bridge Maitri Setu has been built over Feni river which flows between Indian boundary in Tripura State and Bangladesh. The name Maitri Setu symbolizes growing bilateral relations and friendly ties between India and Bangladesh. The construction was taken up by the National Highways and Infrastructure Development Corporation Limited at a project cost of  133 Crore rupees. The 1.9 Kilometres long bridge joins Sabroom in India with Ramgarh in Bangladesh. It is poised to herald a new chapter for trade and people to people movement between India and Bangladesh. With this inauguration, Tripura is set to become the Gateway of North East with access to Chittagong Port of Bangladesh, which is just 80 Kilometres from Sabroom.

The Prime Minister will also lay foundation stone for setting up an Integrated Check Post at Sabroom. It will help ease the movement of goods and passengers between the two countries, provide new market opportunities for products of North East states and assist seamless movement of passengers to and from India and Bangladesh. The project is being taken up by the Land Ports Authority of India at an estimated cost of about 232 Crore rupees.

The Prime Minister will also lay the foundation stone of NH 208 connecting the Unakoti district headquarters at Kailashahar with the Khowai district headquarters. It will provide an alternative route to the NH 44. The 80 Kilometres NH 208 project has been taken up by the National Highways and Infrastructure Development Corporation Limited with a project cost of one thousand 78 Crore rupees.

The Prime Minister will also inaugurate State Highways and other district roads, developed by the State government with a financial outlay of 63.75 Crore rupees. They will provide all weather connectivity to the people of Tripura.

The Prime Minister will inaugurate 40 thousand 9 hundred 78 houses constructed under Pradhan Mantri Awas Yojana (Urban), completed with the financial outlay of 813 Crore rupees. He will also inaugurate the Integrated Command and Control Centre built under Agartala Smart City Mission.

The Prime Minister will lay the foundation stone for the development of Multi Level Car Parking and Commercial Complex at Old Motor Stand. It will be developed at a cost of about 200 crore rupees.

The work is being implemented by Agartala Smart City Mission at a project cost of about 96 crore rupees.

The Ozone Hole

Ozone is a reactive gas mostly found in the so-called ozone layer in the lower stratosphere. The highest ozone concentrations are usually seen at altitudes between 20 and 40 km (at the poles between 15 and 20 km). But it is a very thin layer of about 1-10 ppm (parts per million) ozone. In both the formation and the destruction of ozone, UV radiation is absorbed. Under the influence of UV radiation, oxygen molecules are split into oxygen atoms. The adsorption of UV radiation by the ozone layer is crucial, for without it, life on land would be impossible. 

However, over-exposure to UV radiation will have a variety of damaging effects: Genetic mutation and subsequent effects on health, damage to living tissues, Cataract formation in eyes, skin cancers, suppression of the immune system, Damage to photosynthetic organisms, especially phytoplankton, damage to consumers of photosynthetic organisms, especially zooplankton. 

UV radiation can cause mutations — changes in a species’ DNA. This risk is especially high in Australia and New Zealand where the number of cases of skin cancer in humans has increased dramatically. People arc advised to wear clothes on the beach and to use sun blocks to protect their skin. In New Zealand the daily weather report in summer includes isolines to show burn times. 
It also causes cataracts in the lenses of eyes when the protein of the lens denatures and turns cloudy instead of dear, causing blindness if untreated. 

Since the 1950s, scientists have been measuring the amount of ozone in the stratosphere above Antarctica. They discovered what later would be called the ozone hole: the amount of ozone decreased significantly during the spring (September and October) and increased again in November. Apart from this annual ozone cycle, the scientists discovered that the ozone hole was growing. During the last 30 years, the minimum thickness of the ozone layer has reduced drastically and recovery has been taking longer. These results were later confirmed by NASA satellite data. Reductions in the amount of stratospheric ozone have been observed in other areas including the arctic region.
Ozone is depleted because of human-made substances called Ozone-depleting substances (ODS), like chlorofluorocarbons and methyl bromide in pesticides. While replacing CFCs in spray cans and as blowing agents for plastic foam is relatively easy, it is much more difficult to find a suitable refrigerant. The refrigerants used before the introduction of CFCs are not an option because of their dangerous properties. The most suitable CPC replacements are the so-called hydrochlorofluorocarbons (IICFCs). These substances are nearly as good as refrigerants as CFCs and are also non-toxic and inflammable. However, HCFCs also destroy ozone and they contribute to the greenhouse effect. Only their shorter lifetime in the atmosphere makes them less harmful to the ozone layer than CFCs. 

The Montreal Protocol was an international agreement at the UNEP deciding to regulate the use of CFCs, and it succeeded to a great degree as their usage has decreased since the late 80s, partly because it was the first universally ratified international agreement. More international cooperation to battle threats like the thinning of the ozone layer is the need of the hour.
