Researchers at Helsinki University in Finland have developed the world’s first vaccine to protect bees against disease to fight off severe microbial diseases that can be fatal for pollinator communities. This vaccine raises hopes for tackling the drastic decline in insect numbers which could cause a global food crisis.
The treatment is administered to the queen bee via a sugar lump, similar to the way many children are given polio vaccines. The queen then passes the immunity to her offspring, spreading it through the bee community.
Bees are vital for growing the world’s food as they help fertilize three out of four crops around the globe, by transferring pollen from male to female flowers. But in recent years bee populations around the world have been dying off from colony collapse disorder, a mysterious scourge blamed on mites, pesticides, virus, fungus, or some combination of these factors.

The migratory birds at the Chilika lake, Odisha are facing a threat to their lives due to the detection of avian influenza virus. Some crows and chickens were found dead inside poultry farms in Krushnaprasad block last week. When sent for testing to the National Institute of High-Security Animal Diseases, Bhopal, it was found that the birds were tested positive for H5N1 virus. The State government has planned for a massive culling operation inside private poultry farms in the affected villages.
The Puri district administration would cull birds within one km radius of the place where the carcasses were found. Besides, officers of the animal husbandry department have been asked to intensify surveillance in 10 km-radius area.
It should be noted that around seven lakh migratory birds have arrived at the Chilika lake this year.

The National Green Tribunal (NGT) appointed a joint committee to look into a plea alleging operation of hazardous industries in south-east Delhi’s Sarita Vihar.
The instructions came after a plea moved by the Aali Vihar Vikas Manch, which alleged that hazardous dyeing units were operating in Bhim Colony, Aali Vihar, and Sarita Vihar.
A Bench headed by NGT Chairperson Justice Adarsh Kumar Goel appointed a joint committee comprising representatives from the Central Pollution Control Board (CPCB), the Delhi Pollution Control Committee and Sub-Divisional Magistrate of South-East district, to take action. The Bench made this decision as it observed at least 50 factories are causing air, water, and noise pollution in the area and also choking the water-flow systems. If the drains get choked, the water spills out onto the roads. The hazardous chemicals are highly affecting the water quality.

Researchers at the University of Bonn in Germany found that Bioplastics, often promoted as a climate-friendly alternative to petroleum-based plastics, may lead to an increase in greenhouse gas emissions. But shifting to plant-based plastics could have less positive effects than expected.
An increased consumption of bioplastics in the following years is likely to generate increased greenhouse gas emissions from cropland expansion on a global scale. Plastics cause fossil fuel depletion and climate change. It is estimated that by 2050, plastics could already be responsible for 15% of the global CO2 emissions.
On the other hand, bioplastics are in principle climate-neutral since they are based on renewable raw materials such as maize, wheat, and sugarcane. These plants get the CO2 that they need from the air through their leaves. The study found that it takes a lot of time for the switch to bioplastics to pay off.

Researchers at the University of East Anglia (UEA) and the Global Carbon Project said that Global carbon emissions are set to hit an all-time high of 37.1 billion tonnes of CO2 in 2018. Among all the countries India is the third-highest contributor of CO2. India has projected to see emissions rise by 6.3% from 2017.
Representatives from more than 190 countries have begun discussions at the U.N. Climate Change Conference (COP 24) in Katowice, Poland. The discussion is to set ways to equitably cut carbon emissions.
Limiting global warming to the 2015 Paris Agreement goal of keeping the global temperature increase this century to well below 2°C, would need carbon dioxide emissions to decline by 50% by 2030 and reach net zero by about 2050.

Researchers from the University of Exeter and Plymouth Marine Laboratory, London working with the Greenpeace Research Laboratories conducted tests on over 100 sea turtles, spanning 3 oceans and all 7 species. The test revealed microplastics in the guts of every single turtle. Synthetic particles were found, the most common being fibres, which can come from clothing, tyres and cigarette filters, and equipment such as ropes and nets.
Out of the studied 102 turtles, more than 800 synthetic particles were found. As the researchers only tested part of each animal’s gut, the total number of particles is estimated to be about 20 times higher.
It is not known how synthetic particles are ingested by turtles, but the likely sources are polluted seawater and sediments and eating via prey or plants.

The Telangana government offices are soon to make way for electric cars as the State aims at promoting non-polluting vehicles. The government has brought in the Electric Mobility Policy 2018-2023 to encourage the use of carbon-free cars. It has followed it up by signing with the Energy Efficiency Services Limited (EESL). The EESL in principle has agreed to invest a whopping Rs.10,250 crore in the State to procure 1,00,000 cars. The State has sought support from two automobile companies, the Mahindra and the Tata and Sons, to provide 100 cars before the end of December.
The two signature electric cars, the Mahindra Verito, and the Tata Tigor, can be charged for six hours with AC charger and 90 minutes with DC charger and can travel for 100-110 km.
It is expected that the introduction of electric cars could provide smart solutions to the concerns over increasing carbon emissions and pave way for cleaner cities, apart from rising in fuel prices. It is estimated that 2.5 kg of carbon and 60 grams of nitrogen are emitted for every litre of diesel. There is a rise in the incidence of lung cancer and respiratory diseases.

The Environment Ministry approved a project led by scientists at the Indian Institute of Technology (IIT) Kanpur to induce artificial rain via cloud seeding in Delhi. The objective is to clear smog in Delhi. The success of the project depends on the presence of a minimum quantity of rain-bearing clouds over Delhi.
In the project, an aircraft has been planned to fly into the clouds and inject silver iodide, which will lead to the formation of ice crystals that will make the clouds denser, cause them to condense into rain and settle atmospheric dust enough to clear the sky.
Researchers at IIT-Kanpur will use an aircraft of the National Remote Sensing Agency, an ISRO-affiliated body for the exercise. The Indian Meteorological Department (IMD) will provide forecasts on the likelihood of conducive clouds. Delhi’s Air Quality Index (AQI) on 20 November was in the very poor category.

Indian cities are finding it difficult to monitor the air pollution for the entire city using a single monitoring system. Nowadays real-time monitoring of air quality has become absolutely necessary for the timely intervention to check pollution levels. Most Indian cities do not have more than one continuous monitoring system.
Experts say that a single Continuous Ambient Air Quality Monitoring System would make a solution to this problem. But such a device cannot represent an accurate picture of air pollution for the entire city. And this, according to them, becomes a problem when emergency measures need to be taken.

Scientists at the Integrated Coastal and Marine Area Management Project Directorate at Chennai’s National Institute of Ocean Technology recorded fluorescent blue and green microplastic particles and fibres are found in species of marine worms. Research says that Microplastics are practically everywhere. Microplastics are an issue because once inside the bodies of marine life forms, they can cause internal lesions.
Apart from accumulating toxins, microplastics can threaten microfauna such as plankton (tiny, single-celled creatures that fish and even whales feed on) that thrive in oceans. Now, scientists have recorded these tiny plastic particles, less than one millimetre in length, closer home, in the marine life off the Kochi coast. Invertebrates dwelling on the ocean floor as well as fish now house microplastics.
Species found with microplastics are:
♦ Marine worms (Sternaspls scutata & Magelona cinta)
♦ Bivalve (Tellina)
♦ Sardines (Mathi) (All fished off Kochi coast)
♦ Anchovies (Natholi) - Punnapra

Scientists from the Intergovernmental Panel on Climate Change (IPCC) said that the world’s oceans have absorbed 60% more heat than previously thought over the last quarter of a century leaving Earth more sensitive still to the effects of climate change.
The Scientists also said that the world’s oceans have absorbed 90% of the temperature rise caused by man-made carbon emissions. But new research found that for each of the last 25 years, oceans had absorbed heat energy equivalent to 150 times the amount of electricity mankind produces annually. That is 60% higher than what previous studies showed.
The IPCC warned that drastic measures need taking in order to limit global warming to 1.5 Celsius by the end of the century but the world produced a record amount of carbon emissions in 2017.

The scientists of Zoological Survey of India (ZSI) has revealed that Moths (Lepidoptera), which is widely considered as pests, are pollinators to a number of flowering plants in the Himalayan ecosystem. The scientists collected moth samples from states such as Arunachal Pradesh, Sikkim and West Bengal. The analysis of proboscis, a long and thread-like organ used to suck flower sap, of a dozen moth species’ revealed the presence of pollen grains.
Researchers have pointed out that almost two-thirds of common large moth species have declined over the last 40 years in some parts of the world. One of the main reasons for the decline is light pollution.

A clutch of seven tiny snakes was released into the wild after spending nearly 80 days in an incubator at the civic body’s Wildlife Paramedical Centre, Karnataka. While incubating the snakes resembled no more than little worms. A BBMP wildlife rescue volunteer rescued the clutch of seven snake eggs from a sump in Hegde Nagar. The mother, a common Kukri species, was also rescued.
While common Kukri is found widespread across the sub-continent, it's sighting in the city has become rare owing to habitat loss. The mother was rescued and released in a nearby garden, while the eggs were taken to BBMP Forest Cell’s wildlife centre. When snakes lay their eggs, they choose a variety of factors including predators and temperature (25 to 26 degrees Celsius). It is difficult to replicate this process in gardens. Hence the eggs were artificially incubated. After all seven eggs hatched, it was released into gardens of the city.

Center for Biological Diversity petitioned U.S. Fish and Wildlife Service to list Pacific Walrus as a threatened species because of diminished sea ice brought on by climate warming. Pacific walrus prefers sea ice for moulting, mating, nursing and resting between dives for food. Pacific walrus males grow to 12 feet long and up to 1,815 kg. Females reach half that weight. Walruses dive and use sensitive whiskers to find clams and snails in dim light on the seafloor.
Fish and Wildlife Service said that inaccessibility protected walruses for decades, but a rapid decline in summer sea ice has made them vulnerable. In the Chukchi Sea between Alaska and Russia, where Pacific walrus females and juveniles spend their summer, ice could be absent during that season by 2060 or sooner.
