The biggest source of variability in the microbiome is the person-to-person variability. It’s a problem if you’re looking for causality. That’s a red flag word for us – causality – meaning something about the bacterial community causes some disease. You actually don’t know whether it’s the bacteria or whether the bacteria are a sign of something that happened before. It’s very much individualized, so everybody’s history matters.

We are all teeming with bacteria that help us digest food or fight disease, but two people might play host to a very different array of bacteria due to diet, where they live, hobbies or even medical histories.

As a result, scientists have struggled to understand which bacteria are linked to disease and which protect against it. Studies comparing people’s bacterial companions – known as the microbiome – to explore what that variation means might disagree because they analyzed different groups or didn’t sample enough people.

China says it is working to develop a solar energy plant in space that could one day beam enough power back to Earth to light up an entire city.

If scientists can overcome the formidable technical challenges, the project would represent a monumental leap in combating the Earth’s addiction to dirty power sources which worsen air pollution and global warming.

A space-based solar power station could also provide an alternative to the current generation of earthbound and relatively ineffective renewable energy sources.

Homeless free-floating planets are likely to be rampant within the Milky Way, says new study. Young, dense loose clusters of stars are pretty raucous places early in their evolution.

NEW YORK (AP) — Did you hear what happened when Bill Gates walked into a bar? Everybody there immediately became millionaires — on average.

That joke about a very rich man is an old one among statisticians. So why did Peter Smibert use it to explain a revolution in biology?

Because it shows averages can be misleading. And Smibert, of the New York Genome Center, says that includes when scientists are trying to understand the basic unit of life, the cell.

At The New Work Summit some of the smartest people in technology across the country pondered how to make A.I. trustworthy.

Infections with BMMF („Bovine Milk and Meat Factors ) in humans provide a clue, why the consumption of cow milk and meat correlates with colon and breast cancers.

Researchers at UCLA have made a major advance in the battle against cancer by showing that it’s possible to create mature T cells with important cancer-killing receptors from pluripotent stem cells. The results could be off-the-shelf T cell cancer therapies for people who need them.
