Virus particles, such as SARS-CoV-2, which are suspended in the air following an infected person s cough or sneeze can become attached to pollen grains and be dispersed in a breeze, causing it to spread farther and faster, say researchers from the American Institute of Physics.
The team used computer modelling and physics to mimic the pollen movement from a willow tree, and simulated outdoor gatherings of up to 100 people, with some of them shedding Covid particles. The people in the crowd were then exposed to 10 000 pollen grains.
Based on what the scientists found, the two-metre rule, therefore, may be less effective even in outdoor settings, they concluded, and urged people to avoid gathering close to types of plants or trees known to be active during the pollen season.

Instant COVID-19 Test Results: Imagine how useful it would have been if COVID-19 in a person could be detected within a few minutes of testing. It would have certainly reduced the immense pressure that the healthcare system across the world is going through. Innovations in the field are of utmost importance to provide a support to the healthcare system. Self-testing kits that can provide the results within a very short span of time is the need of the hour. Now, this has been made possible. Yes, the researchers from the University of Florida and Taiwan’s National Chiao Tung University have made it possible to detect COVID-19 within just one second.

Four months into his administration, President Biden’s approach to climate change is beginning to cohere around two executive orders he issued his first week in office.
Signed on Inauguration Day, the first order set an urgent tone through high-priority moves, such as rejoining the Paris climate agreement, initiating an update of government benchmarks for the social cost of greenhouse gases, and reversing a number of Trump administration actions on environmental policy.
The second order, issued Jan. 27, established an array of policymaking mechanisms and outlined an agenda on matters such as climate resilience, environmental justice, and climate-related economic opportunities, with many action items due within 60, 90, and 120 days.
