By 2020, more people in the world will have a smartphone than running water

Everyone around you right now probably has a smartphone. Youre probably reading this article on a smartphone.

But it may not be that way in other parts of the world for now.

A new report from Cisco says that by 2020, there will more people around the world who own a cell phone than those who have electricity or running water. In fact, 5.4 million people around the world will be seeing their hotline bling, whereas only 5.3 billion people will have water and 3.5 billion will have running water.

To put that number even more in perspective, by that time there will be 2.8 billion cars on the road across the world, CNET reported.

That means that by 2020, cell phone use will make up 81 percent of total mobile data traffic, the report said. Three-fourths of that is expected to be video traffic alone, according to the report.

"The mass adoption of phones underscores society's increasing reliance on handsets for all facets of life. Yes, you can use the device to make a call, but you can also message your friends and families, pay for goods and services, turn on the lights in your home or binge-watch 'Boardwalk Empire,'" CNET reported.

But its not just cellphones thatll increase during this time. The report also said that there will be 11.6 billion mobile-ready tech devices up from the 7.9 billion there were last year due to the increase in wearable technology, like FitBits and Apple Watches. This will only increase as mobile networks increase their abilities, jumping to a superfast 5G wireless technology to truly kick off in wide scale, CNET reported.

Impoverished nations across the world will likely have the most amount of mobile traffic growth overall. The Middle East and Africa specifically will see a 117 percent increase in 2015, with Asian Pacific nations seeing an 83 percent growth and Latin America growing by 73 percent, the reported said.

This comes at a time when developing nations have seen some increases in Internet capable technology, but not a significant amount. As the Pew Research Center found, only 24 percent of the worlds developing and emerging nations have mobile-ready smartphones.

The United States sits well above the rest, with 58 percent of the population owning a smartphone that can connect to the Internet. But less developed nations, like Pakistan (4 percent), Uganda (5 percent) and Tanzania (8 percent), dont have that luxury.

Smartphone ownership is also higher among the more educated, Pew explained. In all of the nations polled, those with a secondary degree or higher are more likely to own a smartphone than the less educated. This is especially true in Jordan, where 67% of the well-educated own a smartphone, compared with just 13% of those with less education a difference of 54 percentage points. A similar gap exists in Chile.

But to become more educated, people may need access to these smartphones. A worldwide report in 2014 from UNESCO found that hundreds of thousands of people in these developing nations often use smartphones and mobile phones to read, since they have access to electronic books that can be purchased cheaply and easily. In fact, 62 percent of respondents in the report said they read more because they could read on their phone.

This is especially helpful in countries where cellphones are easy to buy, but books are not. About 10 percent of respondents said that phones made their reading more affordable than print, and another 9 percent said that it was their only access to books.

How do we bring text to the unreached? the report asked. The answer at least in the immediate term is mobile devices, and more precisely mobile phones.

This can be especially important for womens education moving forward, too. The UNESCO report said that reading through smartphones allows women to find easy ways to read without worrying about the repercussions of finding actual books. Thats good news since women read six times more than men, Time reported.

And that empowerment may have already begun. In October 2015, Tata Communications and MasterCard, two major worldwide companies, joined together to provide more than 100 million women with mobile tech devices over the next five years, The Huffington Post reported. They will start in India, Nigeria, Indonesia and Guatemala, hoping to reach a total of 25,000 women in those countries in the next few years.

Overall, the goal is to help these women find better access to their bank accounts, books to read and keep in touch with their digital financing.

Three billion people will come online over the next decade primarily from the developing world, Rangu Salgame, CEO, Growth Ventures Group, Tata Communications, said in a statement. We now have our generations greatest opportunity to unshackle women from endless cycles of poverty and dependency by providing them with access to information and economic opportunities.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
