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
There may be a ninth planet lurking in the fringes of our solar system. More clues about where to search for it are coming from the Kuiper (KY-pur) belt. That’s a band of icy debris beyond Neptune. New calculations suggest the mystery planet might be brighter — and a bit easier to find — than once thought.
Evidence for a “Planet Nine” is scant. The orbits of six distant objects in the...Readability Score: 7.3
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.
To lock up the new information, start burning those calories roughly four hours after you take in new information. That’s the recommendation of ...Readability Score: 7.9
Some people think electronic cigarettes, which don’t contain tobacco, are a safer alternative to true cigarettes. But smoking e-cigarettes, or vaping, exposes people to toxic gases that can harm the lungs and cause other health problems. Now, a new study shows that the hotter an e-cig gets — and the more it’s used — the more toxic compounds it gives off.

These males can take the heat — an advantage when it comes to global warming. Called valerian plants, they sport small white flowers. One type of bloom grows on male plants, another type on female plants. And in Colorado’s Rocky Mountains, the males and females have responded differently to warmer and drier weather. That’s the finding of a new study.
These plants (Valeriana edulis) grow...Readability Score: 6.6
Even the famous pilot Amelia Earhart couldn’t compete with the great frigate bird. Earhart flew nonstop across the United States for 19 hours in 1932. The frigate bird can stay aloft up to two months without landing, a new study finds. The seabird uses large-scale movements in the air to save energy on its flights across the ocean. By hitching a ride on favorable winds, the bird can spend more...Readability Score: 6.3
The Earth is largely solid or molten rock that’s hot enough to melt iron. So you could never build a tunnel through its diameter. But let’s play a mind game and imagine that you could burrow from one side of the planet through to the other. Physicists play this game all of the time. And falling down a hole through the center of the Earth would be rough, they note. Indeed, some now conclude, it...Readability Score: 6.4
