Why scientists are studying hibernation to tackle obesity

Many mammals gain weight and become insulin resistant during fall. However, these changes are easily reversible, and the mammals will not develop any further unhealthful symptoms. Researchers believe that the explanation for this lies in mechanisms associated with hibernation.

Humans and autoimmune diseases continue to evolve together

The ability to fight disease is a driving force in human survival. Inflammation has emerged as a key weapon in this process. As pathogens change and evolve, the immune system adapts to keep up. Share on PinterestOur DNA’s evolution also brought about autoimmune conditions, researchers explain. However, to what extent might such evolutionary adaptations also […]

What to know about diphallia (double penis)

Diphallia is a rare genetic condition that occurs when a male baby is born with duplication of the penis. There are different types of diphallia, ranging from partial to complete penile duplication. Having two completely developed penises, or true diphallia, is very rare. Ever since the first description of diphallia in 1609, researchers have only […]

Alcohol intake and reduced brain volume: What explains the link?

Does drinking more alcohol shrink the brain, or does a smaller brain volume actually predispose individuals to drink more alcohol? Share on PinterestA new study confirms the link between alcohol use and lower brain volume and proposes a shared underlying cause. Excessive alcohol consumption carries many risks, including heart and liver problems, a higher risk […]
