A study of nearly a half-million Americans has found that following cancer prevention guidelines from the American Cancer Society may modestly reduce your overall risk of developing cancer and have a greater impact on reducing your overall risk of dying. Having a healthy body weight and staying active appeared to have the most positive impact.
At a time when our earliest human ancestors had recently mastered walking upright, the heart of our Milky Way galaxy underwent a titanic eruption, driving gases and other material outward at 2 million miles per hour. Now, at least 2 million years later, astronomers are witnessing the aftermath of the explosion: billowing clouds of gas towering about 30,000 light-years above and below the plane of our galaxy.
In celebration of its 25th anniversary, NASA's Hubble Space Telescope has revisited the famous "Pillars of Creation" region of the Eagle Nebula (M16), providing astronomers with a sharper and wider view. As a bonus, the pillars have been photographed in near-infrared light, as well as visible light.
The largest NASA Hubble Space Telescope image ever assembled, this sweeping view of the Andromeda galaxy (M31) is the sharpest large composite image ever taken of our galactic neighbor. Though the galaxy is over 2 million light-years away, the Hubble telescope is powerful enough to resolve individual stars in a 61,000-light-year-long section of the galaxy's pancake-shaped disk.
Low alcohol consumption and a plant-based diet, both healthy habits aligning with current cancer prevention guidelines, are associated with reducing the risk of obesity-related cancers, a New York University study shows.
In a study at Washington University School of Medicine in St. Louis, researchers found that a subset of obese people do not have common metabolic abnormalities associated with obesity, such as insulin resistance, abnormal blood lipids (high triglycerides and low HDL cholesterol), high blood pressure and excess liver fat. In addition, obese people who didn’t have these metabolic problems when the study began did not develop them even after they gained more weight.
When it comes to skin infections, a healthy and robust immune response may depend greatly upon what lies beneath.

They do it within their Mars environmental simulation chamber, which is specially designed to mimic conditions on the fourth planet from the sun -- right down to its infamous Martian dust.
What makes a person bipolar, prone to manic highs and deep, depressed lows? Why does bipolar disorder run so strongly in families, even though no single gene is to blame? And why is it so hard to find new treatments for a condition that affects 200 million people worldwide? New stem cell research may help scientists find answers to these questions.
A new guideline from the American Academy of Neurology suggests that there is little evidence that most complementary or alternative medicine therapies (CAM) treat the symptoms of multiple sclerosis (MS). However, the guideline states the CAM therapies oral cannabis, or medical marijuana pills, and oral medical marijuana spray may ease patients’ reported symptoms of spasticity, pain related to spasticity and frequent urination in multiple sclerosis (MS). The guideline, which is published in the March 25, 2014, print issue of Neurology®, the medical journal of the American Academy of Neurology, states that there is not enough evidence to show whether smoking marijuana is helpful in treating MS symptoms.
