Bacteria on Skin Enhances Immune Cell Function

The harmless bacteria found on the surface of the skin can enhance the function of immune cells.

What’s the Latest Development?

According to researchers, the harmless bacteria living on the skin is key in fighting disease-causing microbes. “The skin's surface is home to surprisingly diverse communities of bacteria, collectively known as the skin microbiota.” Scientists used mice "born and raised with no naturally occurring microbes on the skin or in the gut to identify how skin microbiota effects immune cell function." “In separate experiments, the researchers found that the presence or absence of microbes in the gut seemed to have no effect on the skin's immune responses. This finding suggests that bacteria have unique roles at different sites in the body.”

What’s the Big Idea? 

Bacteria are viewed as harmful, but that is not the case. There are good and bad bacteria, and the skin’s surface houses many harmless bacteriawhich can “manipulate immune responses and inflammation.” The study shows “these bacteria can play an important role in promoting health by preventing skin infections from becoming more prolonged, pronounced and more serious.”

  • A new study suggests that drinking alcohol can affect how memories are stored away as good or bad.
  • This may have drastic implications for how addiction is caused and how people recall intoxication.
  • The findings may one day lead to a new form of treatment for those suffering from addiction.

Juice is terrible for children. Why do we keep giving it to them?

A glass of juice has as much sugar, ounce for ounce, as a full-calorie soda. And those vitamins do almost nothing.

Quick: think back to childhood (if you've reached the scary clown you've gone too far). What did your parents or guardians give you to keep you quiet? If you're anything like most parents, it was juice. But here's the thing: juice is bad for you.

Heatwaves significantly impact male fertility, says huge study

As the world gets hotter, men may have fewer and fewer viable sperm

Surprising Science
  • New research on beetles shows that successive exposure to heatwaves reduces male fertility, sometimes to the point of sterility.
  • The research has implications both for how the insect population will sustain itself as well as how human fertility may work on an increasingly hotter Earth.
  • With this and other evidence, it is becoming clear that more common and more extreme heatwaves may be the most dangerous aspect of climate change.
