Does heavy use of cell phones pose a risk of cancer? This question has provoked controversy for many years. A new study in rats now adds to those concerns. Its data linked long-term, intense exposure of the animals to radiation from cell phones with an increased risk of cancer in the brain and heart.
The results have yet to be confirmed, the authors note. Moreover, they add, it’s not yet...Readability Score: 6.7
Tweaking the genes of mosquitoes that can carry disease can sometimes transform those blood suckers into weapons that fight disease. This is the finding of a new study in Brazil.
Dengue (DEN-gay) fever is a viral disease spread by Aedes aegypti mosquitoes. This potentially life-threatening infectious disease causes high fevers, headaches, pain and sometimes mild to severe bleeding....Readability Score: 8.1
From ice cream to exercise, too much of a good thing can make people sick. And when people take too much medicine, the effect can be dangerous. That’s why doctors are concerned about the findings of a new survey.
Liquid medicines can be tricky to measure correctly. Doctors recommend measuring drugs with tools such as medicine droppers and oral syringes. They strongly prefer the use of...Readability Score: 7.7
Here’s another reason to get off the couch and start working up a sweat. Time the exercise right and you could just boost your ability to remember something new. That’s the finding of a new study.
But it all comes down to timing.

Not surprisingly, there has been a race to create a Zika vaccine — a drug...Readability Score: 8.2
Being fat isn’t fun for anyone, especially children and teens. It’s not healthy either. Obesity that develops in childhood can set the stage for killer adult diseases, two new studies from Denmark show.
Past studies had shown that being overweight or obese boosts an adult’s risk of developing health problems affecting the heart and brain. But no one had shown that the same was true when...Readability Score: 6.0
PHOENIX, Ariz. — Hundreds of thousands of people in the United States alone suffer from multiple sclerosis. This nervous system disease gradually leads to widespread paralysis. But in most cases, MS patients first lose the ability to open their hands. In time they lose the ability to grip common household items. Now, a teen has invented a device that helps slow the development of this “...Readability Score: 7.2
In recent decades, Earth’s climate has been changing. That’s led to warmer temperatures and more very hot days. At the same time, levels of air pollution are growing. All that heat and dirty air will cause a lot more people to sicken — and even die. That’s the conclusion that emerges from three new analyses of climate trends in the eastern United States.Explainer: How scientists know Earth...Readability Score: 8.0
