Myopia Epidemic Myopia is the most common ocular disorder worldwide, it is the leading cause of visual impairment in children, and its incidence is increasing rapidly. 1,2 In 2010, an estimated 1.9 billion people (27% of the world’s population) were myopic, and 70 million of them (2.8%) had high myopia. These numbers are projected to rise to 52% and 10%, respectively, by 2050 (Figure). 1 Figure. Current and projected 2050 myopia prevalence by region.

Deforestation Deforestation is the permanent removal of trees to make room for something besides forest. This can include clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing. Forests cover more than 30% of the Earth's land surface, according to the World Wildlife Fund. We need to populate our homes more with plants, trees or anything that can generated oxygen for the planet. Moss can be used to clean the air and generate oxygen for the planet.
DNA data storage An alternative to hard drives is progressing: DNA-based data storage. DNA—which consists of long chains of the nucleotides A, T, C and G—is life’s information-storage material. Data can be stored in the sequence of these letters, turning DNA into a new form of information technology. It is already routinely sequenced (read), synthesized (written to) and accurately copied with ease. DNA is also incredibly stable, as has been demonstrated by the complete genome sequencing of a fossil horse that lived more than 500,000 years ago. And storing it does not require much energy. But it is the storage capacity that shines. DNA can accurately stow massive amounts of data at a density far exceeding that of electronic devices. The simple bacterium Escherichia coli , for instance, has a storage density of about 10 19 bits per cubic centimeter, according to calculations published in 2016 in Nature Materials by George Church of Harvard University and his...
