Scientists Build a Yeast Chromosome From Scratch. Next Up? Designer Genomes

Creating synthetic organisms with specially-tailored genomes is a long way off, but the first synthetic eukaryotic chromosome is a big step forward.

Humans have been using what they know about the biological world to make stuff for centuries—from beer to antibiotics. But, what if you could ma... Read More

Rare New Microbe Found in Two Distant NASA Clean Rooms

A rare, recently discovered microbe that survives on very little to eat has been found in two places on Earth: spacecraft clean rooms in Florida and South America.

Microbiologists often do thorough surveys of bacteria and other microbes in spacecraft clean rooms. Fewer microbes live there tha... Read More

Bacteria Proposed for Passaic River Superfund Site Cleanup

A decades long fight over cleaning up one of the nation's most contaminated riverbeds has posed a difficult question: how to safely remove enough toxic material from New Jersey's Passaic River to fill two MetLife Stadiums.

The federal government is moving forward with long-stalled efforts to ... Read More

Stanford bioengineer develops a 50-cent paper microscope

The Foldscope is a fully functional microscope that can be laser- or die-cut out of paper for around 50 cents.

This bookmark-sized microscope can be assembled in minutes, includes no mechanical moving parts, packs in a flat configuration, is extremely rugged and can be incinerated after to s... Read More

Florida Bill Would Combat Superbug Threat

A bill to track drug-resistant infections has been introduced in Florida, inspired in part by FRONTLINE’s Hunting the Nightmare Bacteria.

The bill, sponsored by Rep. Janet Adkins, a Republican, requires the state health department to maintain an online record of the type and location of any a... Read More

Gut Ecosystem Restoration via Fecal Transplantation

Relapsing clostridium difficile infection (CDI) is a disease that patients face after being medicated with antibiotics that damage their microbiota. A recent and effective treatment to eradicate this condition is known as “fecal material transplant” (FMT), where a healthy human will donate a sam... Read More

Will Antibiotics Be There When You Need Them? Get Smart

Just in time for “Get Smart about Antibiotics Week,” I had a refreshing experience recently, working in a different rural hospital. Over that week, I didn’t see one patient with “superbugs” other than the occasional MRSA. No one had the now scarier Gram negative bugs known as ESBLs (extended spe... Read More

Glowing Antibiotics Reveal Bacterial Infections

Despite surgeons’ best efforts, bacteria often manage to sneak onto medical implants such as bone screws, where they can cause severe infections. Research published today in Nature Communications suggests that using fluorescent antibiotics could reveal such infections before they become too seve... Read More

Babies' Weak Immune Systems Let In "Good" Bacteria

As any new parent knows, infants are notoriously susceptible to bacterial infections. A study now suggests that the body engineers this vulnerability deliberately, allowing beneficial microbes to colonize the baby’s gut, skin, mouth and lungs. Learning to manipulate this system could lead to tre... Read More

Photonic tweezers can pick up a single virus with light

A new device from Macquarie University can manipulate objects as small as 50 nanometers wide — about a thousandth of the width of a human hair and small enough to allow direct manipulation of a single viral capsule.

Freshman Biology Creative Projects!

I have found that students become involved, energized, and enthusiastic when I give them opportunities to explore topics in my classes using their own creative approaches and interests. So this semester, in my Biology 111 course at the University of Puget Sound, I found that students explored f... Read More

How many viruses on Earth?

How many different viruses are there on planet Earth? Twenty years ago Stephen Morse suggested that there were about one million viruses of vertebrates (he arrived at this calculation by assuming ~20 different viruses in each of the 50,000 vertebrates on the planet). The results of a new study s... Read More
