New View into Our Guts Reveals Microbiome’s Murky Links to Health

human microbiome gut health

What is living in your gut? It might depend less on your diet, exercise habits, weight and sex than you think, according to new findings. Our health is tied to trillions of organisms that live in and on us. But the extent of their impact has only recently come into focus. And scientists are just [...]

Gut Reaction: Human Colon Replica Demonstrates How E. coli Contaminates Groundwater

false color depiction of E. coli bacteria

Scientists are great at growing E. coli in the lab. They know exactly under which conditions various strains thrive. Unfortunately, there is only so much that can be learned from the bacteria’s behavior in an ideal, isolated and ultimately unrealistic environment. That is why a group of researchers at the University of California, Riverside, decided [...]

What is the dirtiest thing on your desk? If you work in a typical office, it’s not actually your computer mouse or your keyboard or even your desk. According to a new study, published online May 30 in PLoS ONE, it’s your phone—but your chair’s not far behind. Before you drop that receiver or leap [...]

Researchers Engineer Rewriteable Digital Data Storage in the DNA of Living Bacteria

DNA

Engineers have invented a way to store a single rewriteable bit of data within the chromosome of a living cell—a kind of cellular switch that offers precise control over how and when genes are expressed. For three years, Jerome Bonnet, Pakpoom Subsoontorn, and Drew Endy of Stanford University tinkered with the switch in Escherichia coli [...]

Evolution details revealed through 21-year E. coli experiment

evolution bacteria e. coli

In 1988 an associate professor started growing cultures of Escherichia coli. Twenty-one years and 40,000 generations of bacteria later, Richard Lenski, who is now a professor of microbial ecology at Michigan State University, reveals new details about the differences between adaptive and random genetic changes during evolution. Sequencing genomes of various generations of the bacteria, [...]

Researchers produce propane using E.coli bacteria

Diverse_e_Coli

A team of scientists has transformed E.coli bacteria into a propane factory. In their Nature magazine article, researchers from the University of Turku (Finland) and Imperial College (United Kingdom) described a new metabolic pathway for producing propane from Escherichia coli (E.coli). In “normal” E.coli, a biological process exists that turns fatty acids into cell membranes. In their September 2014 [...]

You’ve never really seen a virus until you see this

13-011FEATURE

Artist Luke Jerram is a UK-based sculptor whose glass sculptures of microscopic life make the invisible visible. I was instantly transfixed by his sculptures’ delicacy and intense beauty. For me, something is captured in these sculptures that is lost in the false-color scanning electron microscope images we typically see of viruses and other extremely small [...]

The end of E. coli

Escherichia Coli with Flagella

E. coli‘s career in science has been stellar so far. E. coli lead a simple life as an inhabitant of our guts for thousands of years, until 20th century scientists discovered that the bacterium was easy to grow and manipulate in the lab. E. coli rose to scientific fame and became a laboratory superstar. As [...]
