A gastroenterologist argues that gravity could be a leading cause of IBS, alongside changes in gut microbiome and elevated serotonin levels.

Bad things happen to a human body in zero gravity. Just look at what happens to astronauts who spend time in orbit: Bones disintegrate. Muscles weaken. So does immunity. “When you go up into ...

A new study has revealed that gravity’s effect on Earth is constantly shaping the surface of our planet. When our planet formed, it did so by pulling dust and rock toward its gravitational field.

If urine-specific gravity is high for another reason, such as diarrhea or shock, the healthcare professional will investigate and treat the underlying cause. Learn more about how to manage ...

It could even cause an overgrowth of bacteria in the gut — another cause of IBS. Between 25 and 45 million Americans are blighted by the condition, which is more common in women than men.

Urine specific gravity measures the electrolytes and osmolality of your urine. Learn about what causes it, symptoms, and treatment options today.

After two weeks in space, astronauts experience muscle and bone loss due to the lack of gravity. Bone density also decreases, ...

See how gravity accelerates a bicyclist downhill while drag slows her down. See how gravity accelerates a bicyclist downhill while drag slows her down. Design Squad is available to stream on pbs ...

Without the pull of gravity to work against, muscle mass decreases and muscles begin to atrophy. Within several weeks, astronauts lose up to 10% to 20% of their lean muscle mass.

Think of gravity waves as waves moving through stable air. When you look at waves in the ocean, there are high parts and low parts to that wave. Clouds need lift to materialize in the atmosphere.

Now scientists were arguing about ‌‌the causes of obesity, which affects more than 40 percent of U.S. adults and costs the health system about $173 billion each year.
