Covaxin

Que. What is ‘Covaxin’ and how was it

developed?

 The vaccine candidate was developed by BBIL in collaboration with the National Institute of Virology (NIV). NIV isolated a strain of the novel coronavirus from an asymptomatic Covid-19 patient and transferred it to BBIL early in May. The firm then used it to work on developing an “inactivated” vaccine — a vaccine that uses the dead virus — at its high-containment facility in Hyderabad.

“Once the vaccine is injected into a human, it has no potential to infect or replicate, since it is a killed virus. It just serves to the immune system as a dead virus and mounts an antibody response towards the virus,” said the company, adding that inactivated vaccines usually have a proven safety record.

Oxygen in ocean

Image
  How much oxygen comes from the ocean? Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic  plankton  — drifting plants, algae, and some bacteria that can photosynthesize. One particular species, Prochlorococcus, is the smallest photosynthetic organism on Earth. But  this little bacteria produces up to 20% of the oxygen in our entire biosphere . That’s a higher percentage than all of the tropical rainforests on land combined. It’s important to remember that although the ocean produces at least 50% of the oxygen on Earth, roughly the same amount is consumed by marine life. Like animals on land, marine animals use oxygen to breathe, and both plants and animals use oxygen for cellular respiration. Oxygen is also consumed when   dead plants and animals decay   in the ocean. Calculating the exact percentage of oxygen produced in the ocean is difficult because the amounts are con...

Maximum"Oxygen" producer in Earth.

Image
Our atmosphere is made up of roughly 78 per cent nitrogen and 21 per cent oxygen, with various other gases present in small amounts. The vast majority of living organisms on Earth need oxygen to survive, converting it into carbon dioxide as they breathe. Thankfully, plants continually replenish our planet’s oxygen levels through photosynthesis. During this process, carbon dioxide and water are converted into energy, releasing oxygen as a by-product. Covering 5.5 million square kilometres (2.1 million square miles), the Amazon rainforest cycles a significant proportion of the Earth’s oxygen, absorbing large quantities of carbon dioxide at the same time.

Recent droughts in Europe were the worst in 2,100 years.

Image
  Europe has been experiencing serious dry spells and extreme heat since 2015, which has caused major droughts. Research done led by the University of Cambridge (and published on the  National Oceanic and Atmospheric Administration  website) looked at isotopes in the rings of old European Oak trees in Central Europe which formed over thousands of years to try to pin down the cause. They discovered that  the dry spells  are a "result of human-caused climate change and associated shifts in the jet stream," according to EurekAlert!

The Smallest guitar

Image
  The smallest guitar in the world is of the size of a red blood cell The  world's smallest guitar  is of the size of a  red blood cell. It was developed by scientists from  Cornell University.US The nano  guitar has six strings each of 50 nano meters wide.When  plucked by an atomic force microscope ,the strings would resonate.But it will at be inaudible frequencies. The first of its kind was made in Cornell University in 1997. The nano guitar was made from crystalline silicon.It is about  10 micrometers long .It can be viewed with the help of an  electron microscope .

Carbon Cycle

Image
  What is the carbon cycle? Carbon is the foundation of all life on Earth, required to form complex molecules like proteins and DNA. This element is also found in our atmosphere in the form of carbon dioxide (CO2). Carbon helps to regulate the Earth’s temperature, makes all life possible, is a key ingredient in the food that sustains us, and provides a major source of the energy to fuel our global economy. The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change. Where the carbon is located — in the atmosphere or on Earth — is constantly in flux. On Earth, most carbon is stored in rocks and sediments, while the rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs, or sinks, through which carbon cycles. Carbon is released back into the atmosp...

How glaciers hold water

Image
  Glaciers and ice sheets hold about 69 percent of the world's freshwater. Glaciers are a big item when we talk about the world's water supply. Almost 10 percent of the world's land mass is currently covered with glaciers, mostly in places like Greenland and Antarctica. You can think of a glacier as a frozen river, and like rivers, they "flow" downhill, erode the landscape, and move water along in the Earth's water cycle.
