On the contrary, large size plastics are decomposed into small-sized plastics over a period of time due to exposure to sunlight. These broken plastics, which are called microplastics, blend in our environment in a way that they are unidentifiable. Microplastics are very small pieces of plastics with size less than 5 millimeters. The microplastics enter our environment in two ways. On one hand, small-sized plastics are created for the purpose of cosmetics, face wash, and in some cases microfilaments come out of the garment products. On the other hand, the plastic waste such as plastic bags and water bottles that we lay in the garbage decompose into smaller particles over a period of time. It is estimated that about 12.7 million tons of plastics are dumped into the ocean every year.

Building world's 1st pyramid
In a preprint study published this summer, researchers proposed that ancient Egyptians built the world's first pyramid the 4,700-year-old Step Pyramid of Djoser, which sits on Egypt's Saqqara plateau using a \"modern hydraulic system\" powered by a long-gone branch of the Nile River.

A new class of antivirals could help prevent future pandemics
The arrival of Paxlovid in December 2021 marked another turning point in the COVID-19 pandemic an effective antiviral that has since successfully treated millions.
Turning carbon emissions into methane fuel
Chemists have developed a novel way to capture and convert carbon dioxide into methane, suggesting that future gas emissions could be converted into an alternative fuel using electricity from renewable sources. Carbon dioxide (CO2) is a greenhouse gas that accounts for a large part of Earth's warming climate, and is produced by power plants, factories and various forms of transportation.
