Young children who spend too much time in front of a screen are not getting enough sleep, and especially if they are being sneaky about using it, according to the results of a new U.S. study.

Carried out by researchers from the University of Michigan, the study looked at levels of screen time among 278 preschoolers with an average age of 4 years old, including DVD/VCR, video games and computer/internet usage.

The researchers asked the children's parents and guardians to complete a questionnaire about their child's bedtime behavior, reporting the hours of nightly sleep, daily naps, and quantity and times of media usage.

Intel and AMD announce first Core i5 and i7 chips with Radeon graphics

  Intel and AMD announce first Core i5 and i7 chips with Radeon graphics Back in November, longtime rivals Intel and AMD shocked the computing world when the two companies announced that they’d be teaming up to create laptop chips that combined Intel’s Core line of processors with AMD’s Radeon graphics. And now at CES 2018, the first fruits of that partnership have been revealed, in the form of a pair of Intel Core i5 and i7 chips powered by discrete AMD Radeon RX Vega M GPUs. Along with the processor and GPU, each unit also has 4GB of HMB2 VRAM onboard, which Intel says should help drastically save space internally for laptops while increasing battery life.

The study found that children got more sleep if parents limited screen time , which also resulted in lower risk of obesity. (HealthDay)—The opioid epidemic continues to chip away at the average American life span, federal health officials reported Thursday.

Parents were also asked to answer questions about "sneaky" media use, to find out how often children are caught using media when they should be sleeping.

The team found that increased media use was associated with getting a shorter night's sleep and taking a longer daytime nap.

In particular, children who were caught sneakily using media when they should be sleeping were found to sleep less at night, take longer daytime naps, and go to bed later on weekdays compared to children who didn't sneakily use media -- all factors that can negatively impact a child's healthy development.

The team were also not surprised to find that children who had televisions in their bedrooms were 127 percent more likely to engage in sneaky media use compared to those without a TV in their room.

Visa will make signatures optional for chipped credit cards

  Visa will make signatures optional for chipped credit cards It's been about a month since American Express and Mastercard decided to stop requiring signatures for EMV chip credit cards. "Visa is committed to delivering secure, fast and convenient payments at the point of sale," said VIsa's Dan Sanford in a statement. "Our focus is on continually evolving the market towards dynamic authentication methods such as EMV chip, as well as investing in emerging capabilities that leverage advanced analytics and biometrics. We believe making the signature requirement optional for EMV chip-enabled merchants is the responsible next step to enhance security and convenience at the point of sale.

In addition, the results also revealed that children who were the heaviest media users in the study were also likely to have parents who were heavy media users, with the researchers suggesting that the problem should be addressed for the whole family and not only young children.

Commenting on the findings, study authors Jessica Moorman and Kristen Harrison said that media use can "chip away" at a restful night's sleep for young children and reduce their ability to get the 10-13 hours of sleep they need per night.

Although the results showed that on average, parents reported that their children clocked up nearly 11 hours of sleep per day, Moorman still expressed concern about the timing of this sleep.

"As kids age, they typically grow out of the need for a daily nap, and this process is called 'sleep consolidation,'" Moorman explained, "Although these children may be meeting their required hours of sleep during any given 24-hour period, a longer daytime nap suggests a disruption to a child's process of sleep consolidation."

Previous research indicates that children aged 2-5 should only use screen media for about one hour a day to ensure their healthy growth and development, however the current study revealed that daily screen time for preschoolers was more than double this recommendation.

Inadequate sleep among children has previously linked to obesity, depression and anxiety, as well as poor school performance and poor social behaviors.

The findings can be found published online in the journal Health Communication.
