E-cigarettes can contain nicotine but not many of the harmful substances produced by smoking tobacco, such as tar or carbon monoxide. These products work through an inhalation-activated system that heats a solution to create an inhalable aerosol, often known as vapor.

The observational study in nearly 20,000 participants suggests that coffee can

A comparison of 2 different fitness routines shows that both can have an anti-aging effect on the brain in the elderly, but only dancing gives rise to a measurable difference in behavior.

New research sheds light on how obesity increases the risk of cancer. Credit: © hin255 / Fotolia It’s been well established that obesity is a contributor to cancer risk, but how it actually causes cancer is still a question that hasn’t been fully explained. A new Michigan State University study now offers new details showing

Babies only hours old are able to differentiate between sounds from their native language and a foreign language, scientists have discovered. The study indicates that babies begin absorbing language while still in the womb, earlier than previously thought.

Low-calorie diets can extend longevity, but new research is the first to show that calorie restriction influences the body’s circadian rhythms’ involvement with the aging process in cells. Credit: © photka / Fotolia cientists studying how aging affects the biological clock’s control of metabolism have discovered that a low-calorie diet helps keep these energy-regulating processes

Network of synthetic-lethal interactions connecting commonly mutated genes to potential drug targets.

This concept is called “synthetic lethality” because the drug is only lethal

When Yale researchers took a closer look at skin cells, they discovered the unaffected neighbor
