April 2018 Update Is Now On Almost 90% Of Devices


Europe, and to some extent North America, remain the regions with the most comprehensive data on air quality. In many low- and middle-income countries, while PM2.5 measurements are still not available, they have seen large improvements for\r\n measurements between the last database update in 2018 and this one, with an additional 1500 human settlements in these countries monitoring air quality.

Social media plays a big role in teen culture today. Surveys show that ninety percent of teens ages 13-17 have used social media. Seventy five percent report having at least one active social media profile, and 51% report visiting a social media site at least daily. Two thirds of teens have their own mobile devices with internet capabilities. On average, teens are online almost nine hours a day, not including time for homework.There are positive aspects of social media, but also potential risks. It is important for parents to help their teens use these sites responsibly.


On June 11, 2018, CMS announced a change to the way that fee schedule amounts for DME are established, indicating that prices paid by other payers may be used to establish the Medicare fee schedule amounts for new technology items and services. The innovative aspects of this change in the pricing methodology for DME are intended to ensure that Medicare is expeditious and responsive to providing reimbursement and access to new technology and devices for beneficiaries.


Over the last decade, the proportion of adults purchasing from UK sellers has consistently remained far higher than the proportion purchasing from other countries. However, the percentage who purchased from other EU countries over the same period has almost trebled, rising from 12% in 2008, to 33% in 2018. Similarly, the proportion purchasing from the rest of the world has also increased, from 18% in 2008, to 35% in 2018.


In 2018, of all employed adults aged 35 to 44 years, 83% used computers or portable devices at work, the highest proportion across all age groups. Of those aged 16 to 24 years, 51% had needed to learn how to use new software or computerised equipment in the last 12 months for their jobs, compared with 15% of employed adults aged 65 years and over.


Colorado ranks eighth among the states in estimated recoverable coal reserves.81,82 The state produces coal from both underground and surface mines. Currently, mining is focused in the Green River, Piceance, and San Juan Basins.83 Colorado's coal is used almost entirely for electricity generation, but the market for the state's coal has decreased and several Colorado mines have closed as the share of U.S. electricity generated by coal-fired power plants continues to decline.84,85,86,87 Although Colorado's coal production increased for the first time in six years in 2017, due to an increase in foreign demand for U.S. coal, production continues to decline.88,89,90 In 2018, Colorado coal producers exported almost 25% of the state's mined coal to other countries, but exports declined to 7% in 2020.91 Almost two-thirds of the coal mined in Colorado is used for power generation within the state. Coal is also transported for electric power generation or used at industrial plants in 16 other states.92
