Many things change in space, including how the intestines function. Constipation is a known side effect of space travel, but until now, little has been known about why it happens. Constipation is a familiar problem for astronauts, but the biological reason it develops during spaceflight has remained uncertain. Researchers from the University of Copenhagen working […]

Pomegranates Could Unlock a New Treatment for Heart Failure
A compound produced in the body after eating pomegranates improved heart function by up to 80% in experimental models of a type of heart failure with limited treatment options. For people with heart failure with preserved ejection fraction, the heart can still pump blood but struggles to relax and refill properly between beats. In experimental […]
Africa’s Giant Herbivores Were Disappearing Millions of Years Before Humans Could Hunt Them
Africa’s giant herbivores did not simply vanish in a wave of extinctions. Their evolutionary family tree was slowly running out of new branches. A new study suggests that the long decline of animals such as elephants, hippopotamuses, and their extinct relatives was driven primarily by low rates of speciation. Once a giant species disappeared, another […]

This Utah Mountain Is Hiding Enough Ice To Fill 600 Olympic Pools
A mountain of loose rock in Utah hides enough ice to fill 600 Olympic swimming pools, revealing that some of the state’s largest frozen water reserves are almost invisible from the surface. Unlike conventional glaciers, which expose broad expanses of ice, rock glaciers resemble slowly shifting fields of broken stone. Their rocky coverings can conceal […]

Vagus Nerve Stimulation Could Unlock the Brain’s Hidden Learning Potential
Practice may teach the brain a new movement, but what happens immediately afterward could determine whether that skill lasts. Scientists have long known that repetition alone does not guarantee learning. A newly practiced movement must be stabilized through memory consolidation, a process that continues after training ends. New research in mice suggests that signals arriving […]
