Experiments on the ISS have shown that young spruce tree seedlings do grow in microgravity, but they don’t look quite the same. The seedlings grow faster, and the pine needles don’t point downward so much. DNA analysis shows that several plant genes are more active in space, but we’re still waiting to find out the long-term effects on larger plants. Plants in space  are  plants  grown in  outer space  typically in a weightless but pressurized controlled environment in specific space gardens. [ In the context of human spaceflight, they can be consumed as food and/or provide a refreshing atmosphere.Plants can metabolize carbon dioxide in the air to produce valuable oxygen, and can help control cabin humidity. Growing plants in space may provide a psychological benefit to human spaceflight crews. The first challenge in growing plants in space is how to get plants to grow without gravity.This runs into difficulties regarding the effects of gravity on ...

This is the article on How do plants and trees help the environment? DO TREES REDUCE AIR POLLUTION LEVELS? The relationship between trees and air pollution is a complicated one. Particulate matter suspended in polluted air tends to settle onto leaves, and certain gases including nitrous dioxide (NO2) are absorbed by leaves’ stomata, filtering the air and reducing pollution levels slightly. But trees and other vegetation also restrict airflow in their immediate vicinity, preventing pollution from being diluted by currents of cleaner air. In particular, tall trees with thick canopies planted alongside busy roads can act like a roof, trapping pockets of polluted air at ground level. To reliably improve air quality, city planners need to give careful consideration to how trees are placed.

This is a short article on benefits of laughter yoga: What is Laughter Yoga? Laughter yoga was started by Dr Madan Kataria in the mid-1990s. He started a laughter club with four people, with an agenda to promote the importance of laughter. The club quickly grew to over 50 participants within a few days. In no time, there were over 200 laughter clubs throughout India. By 1999, Kataria had travelled to the US and established the first laughter club outside India. Now, a laughter yoga institute offers training programmes, workshops and seminars on therapeutic laughter. Laughter yoga is a unique form of exercise. It is usually done in groups by sharing jokes and doing playful exercises. People in the group often fake laughter in the beginning until it soon turns into real and contagious laughter. A few breathing exercises that are taught during laughter yoga can be used to relax the body and mind.
