Covid19 antibiotics tested?

Dozens of antibody tests for the novel coronavirus have become available in recent weeks. And early results from studies of such serological assays in the U.S. and around the world have swept headlines. Despite optimism about these tests possibly becoming the key to a return to normal life, experts say the reality is complicated and depends on how results are used.



Antibody tests could help scientists understand the extent of COVID-19’s spread in populations. Because of limitations in testing accuracy and a plethora of unknowns about immunity itself, however, they are less informative about an individual’s past exposure or protection against future infection.

“The focus right now is primarily epidemiological,” says Tara Smith, a professor of epidemiology at the Kent State University College of Public Health. That approach means trying to figure out the percentage of the population that has already been infected even if some individuals never showed symptoms. “This will allow us to better calculate the fatality rate and to determine how far we still have to go to reach [infection] levels that would place us in the range of herd immunity,” or when a large proportion of a population has become immune to a disease because of vaccination or past infection, she says. “It will also allow us to start looking at duration of immunity.”

Northern lights, what is northern lights , Everything about Northern light

Northern lights  WHAT ARE NORTHERN LIGHTS? The bright dancing lights of the aurora are actually collisions between electrically charged particles from the sun that enter the earth's atmosphere. The lights are seen above the magnetic poles of the northern and southern hemispheres. They are known as 'Aurora borealis' in the north and 'Aurora australis' in the south.. Auroral displays appear in many colours although pale green and pink are the most common. Shades of red, yellow, green, blue, and violet have been reported. The lights appear in many forms from patches or scattered clouds of light to streamers, arcs, rippling curtains or shooting rays that light up the sky with an eerie glow. WHAT CAUSES THE NORTHERN LIGHTS? The Northern Lights are actually the result of collisions between gaseous particles in the Earth's atmosphere with charged particles released from the sun's atmosphere. Variations in colour are due to the type of gas p...

One - horned rhino, unique species of rhino

One-horned rhino  The greater one-horned rhino (or “Indian rhino”) is the largest of the rhino species. Once widespread across the entire northern part of the Indian sub-continent, rhino populations plummeted as they were hunted for sport or killed as agricultural pests. This pushed the species very close to extinction and by the start of the 20th century, around 200 wild greater one-horned rhinos remained. The recovery of the greater one-horned rhino is among the greatest conservation success stories in Asia. Thanks to strict protection and management from Indian and Nepalese wildlife authorities, the greater one-horned rhino was brought back from the brink. Today populations have increased to around 3,500 rhinos in northeastern India and the Terai grasslands of Nepal. The greater one-horned rhino is identified by a single black horn about 8-25 inches long and a grey-brown hide with skin folds, which gives it an armor-plated appearance. The species is solitary,...
