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 bacteria—which 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.”
It marks another milestone in SpaceX's long-standing effort to make spaceflight cheaper.
- SpaceX launched Falcon Heavy into space early Tuesday morning.
- A part of its nosecone – known as a fairing – descended back to Earth using special parachutes.
- A net-outfitted boat in the Atlantic Ocean successfully caught the reusable fairing, likely saving the company millions of dollars.
Controversial map names CEOs of 100 companies producing 71 percent of the world's greenhouse gas emissions.
- Just 100 companies produce 71 percent of the world's greenhouse gases.
- This map lists their names and locations, and their CEOs.
- The climate crisis may be too complex for these 100 people to solve, but naming and shaming them is a good start.
The world's richest people could breeze through a climate disaster – for a price.
- A new report from a United Nation expert warns that an over-reliance on the private sector to mitigate climate change could cause a "climate apartheid."
- The report criticizes several countries, including the U.S., for taking "short-sighted steps in the wrong direction."
- The world's poorest populations are most vulnerable to climate change even though they generally contribute the least to global emissions.
