Assortment in colony biofilms

Effect of founder cell density on the spatial pattern formation in colony biofilms.
The colony biofilms were obtained by following the protocol described in van Gestel et al (2014) ISME Journal (doi: 10.1038/ismej.2014.52). Briefly, GFP and mKATE2 labeled Bacillus subtilis strain were mixed in ... Read More

"Crowdsourced" Microbes Heading to the Space Station

NASA Public Affairs Officer Dan Huot talks with Dr. David Coil about Project MERCCURI, which will study a "crowdsourced" collection of microbial samples scheduled to launch to the International Space Station aboard the SpaceX-3 mission.

Tamiflu-resistant influenza: parsing the genome for the culprits

It doesn’t take long for the flu virus to outsmart Tamiflu. EPFL scientists have developed a tool that reveals the mutations that make the virus resistant, and they have identified new mutations that may render ineffective one of the few treatments currently available on the market.

Tamiflu ... Read More

How A Person Can Recover From Ebola

At least eight Ebola patients in Guinea have beaten the odds. They have recovered and been sent home. In past outbreaks, the death rate has been as high as 90 percent. In Guinea so far, about 60 percent of the 157 suspected cases have ended in death.

The first seven to 10 days after infection... Read More

Five new Listeria species found; may improve tests

Cornell researchers have discovered five new species of a group of bacteria called Listeria – including one named for Cornell – that provide new insights that could lead to better ways to detect soil bacteria in food. To date, of the 10 previously known species of Listeria, only two are pathogen... Read More

Popular probiotics have few cons, experts say

Every year, half of all Americans take some kind of pill as insurance against their diets.

But recently, researchers have noticed a surprising trend: Use of some of the most popular supplements is waning, possibly because of recent reports questioning their benefits and raising awareness abou... Read More

Ancient Virus DNA Gives Stem Cells the Power to Transform

A virus that invaded the genomes of humanity's ancestors millions of years ago now plays a critical role in the embryonic stem cells from which all cells in the human body derive, new research shows.

The discovery sheds light on the role viruses play in human evolution and could help scientis... Read More

Guinea's first Ebola survivors return to family, stigma remains

GUECKEDOU, Guinea, April 8 (Thomson Reuters Foundation) - H iccups, say doctors in this remote corner of Guinea, are the final tell-tale sign of infection by the Ebola virus that has killed more than 100 people since an outbreak began this year.

Then come profuse bleeding, circulatory shock a... Read More

Heartland virus disease

Six new cases of Heartland virus disease have been identified in residents of Missouri and Tennessee. The cause of this disease appears to be a member of the Phlebovirus genus in the Bunyaviridae family that was first identified in 2009 and appears to be transmitted by the Lone Star tick (Amblyo...

Evolutionary Battle Explains Why Fruit Spoils

There’s a hidden war going on for your fruit. The apple snatchers and orange thieves aren’t what you might think, though. Humans and other fruit-loving species are locked in an ongoing evolutionary battle against the microbes that also want to feast. Now, researchers believe they have found out ... Read More

Fauci: Robust Research Efforts Needed to Address Ongoing, Global Challenge of Antimicrobial Resistance

Given the evolutionary ability of microbes to rapidly adapt, the threat of antimicrobial resistance likely will never be eliminated. Today, many factors compound the problem, including the inappropriate use of antibiotics and a dwindling supply of new medicines, leading to a global crisis of ant... Read More

Microbial Misadventures: A Malaria Outbreak Without Mosquitoes

Shout “fire” in a crowded room and watch the occupants fly for the exits. Speak the word “malaria” and watch as all within earshot reach for the nearest can of DEET. The incontrovertible fact of malaria’s relationship with mosquitos is one that has been known since Sir Ronald Ross discovered th... Read More

Bacteria get new badge as planet's detoxifier

A study published recently in PLOS ONE authored by Dr. Henry Sun and his postdoctoral student Dr. Gaosen Zhang of Nevada based research institute DRI provides new evidence that Earth bacteria can do something that is quite unusual. Despite the fact that these bacteria are made of left-handed (L)... Read More

One in 25 patients battling hospital-acquired infections: CDC

On any given day, one in 25 hospitalized patients - 4 percent - is battling an infection picked up in a hospital or other healthcare facility, according to a new survey by the Centers for Disease Control and Prevention (CDC).

That translates to more than 600,000 hospital patients each year. R... Read More

Genetic Defect May Confer Resistance to Certain Viral Infections

A National Institutes of Health (NIH) study reports that a rare genetic disease, while depleting patients of infection-fighting antibodies, may actually protect them from certain severe or recurrent viral infections. Researchers found that HIV and influenza viruses replicate in the cells of peop... Read More

Proteins discovered in gonorrhea may offer new approach to treatment

Researchers at Oregon State University have discovered novel proteins in, or on the surface of the bacteria that causes gonorrhea, which offer a promising new avenue of attack against a venereal disease that is showing increased resistance to the antibiotics used to treat it.

Only a single, t... Read More

Scientists re-define what’s healthy in newest analysis for Human Microbiome Project

University of Michigan microbiologist Pat Schloss, Ph.D., describes latest findings from Human Microbiome Project. Based on their findings in today’s Nature, there is no single healthy microbiome. Rather each person harbors a unique and varied collection of bacteria that’s the result of life his... Read More
