The big paradox: Reducing air pollution has INCREASED global warming because clean air does not contain aerosol particles that reflect sunlight and cool the Earth Pollution levels today are 30 percent lower than in 2000 However, this has led to increased warming from carbon emissions Scientists find there is less fog in the atmosphere to block out solar radiation They suggest using solar engineering to launch aerosol particles into the atmosphere in an effort to combat climate change By Stacy Liberatore For Dailymail.com Published: 4:56 p.m. EDT, 22 July 2022 | Updated: 5:51 p.m. EDT, 22 July 2022 Scientists have discovered a great paradox in nature – clean air increases global warming, while pollution keeps our planet cool. An international team of researchers determined current pollution levels are 30 percent lower than in 2000, but warming from carbon dioxide emissions has increased by up to 50 percent. Polluting pa...

Summary: Researchers reveal how astronauts can avoid the neuromuscular problems that occur as a result of extended space travel. Source: Doshisha University Among the many functions performed by skeletal muscles, one of them is maintaining our posture. If it weren’t for these muscles, the gravitational pull of the earth might make it difficult for us to get up and walk. The group of muscles—mostly in our legs, back and neck—that are responsible for maintaining posture and allowing us to move against the force of gravity are called ‘anti-gravity’ muscles. But what happens to these muscles when there is no gravity (or “unloading” force of gravity) to counteract them? That question may sound silly to some, but not to an astronaut on the International Space Station (ISS)! In space, where gravity is minimal, our muscles (especially anti-gravity ones) are not used much, which can lead to atrophy and changes in their structure and properties. In fact, human ca...
