Reports of a person in China dying due to a virus called hantavirus have spread panic at a time when the world is battling the pandemic of the novel coronavirus. hantaviruses are a family of viruses spread mainly by rodents and can cause varied disease syndromes in people across the world. It is important to take note that unlike coronavirus, hantavirus does not spread from one person to another, but rather through touching rodent urine, dripping etc. and then touching your eyes, nose or mouth. Hence, humans who get infected with hantavirus usually come into contact with rodents that carry the virus. As per the CDC, rodent infestation in and around the home remains the primary risk for hantavirus exposure. This virus also spreads when virus-containing particles are stirred in the air and the infection occurs if you breathe in the virus particles present in the air. T...

Sharper images of black hole

According to the new study, scientists have calculated and predicted an intricate internal structure within black hole images caused by extreme gravitational light bending. The study has been published in Science Advances. In this, the lead author Michael Johnson of the Center for Astrophysics Harvard and Smithsonian has described how the swirling ring of photons around a black hole could be the key to unlocking sharp photos. "The image of a black hole actually contains a nested series of rings," Johnson tells IFLScience. "Each successive ring has about the same diameter but becomes increasingly sharper because its light orbited the black hole more times before reaching the observer. With the current EHT image, we’ve caught just a glimpse of the full complexity that should emerge in the image of any black hole." By stacking images of a black hole’s “subrings,” we may one day be able to create a much sharper complete photo of what a black hole looks ...

Does planet 9 exist
