Bacterial Nanowires: Not What We Thought They Were

New videos of morphing bacteria reveal that the strange, distinguishing features of so-called “electric bacteria” aren’t quite what they at first appeared to be.

For the past 10 years, scientists have been fascinated by a type of “electric bacteria” that shoots out long tendrils like electric... Read More

How Ebola Blindsides the Body's Defenses

Researchers often describe the battle between the Ebola virus and the humans it occasionally infects as a race—one that people win only if their immune systems manage to pull ahead before the virus destroys too many of their internal defenses. What they may not know is that the virus is a cheat.... Read More

TWiV 319: Breaking breakbone

The TWiVers review the outcomes of two recent phase 3 clinical trials of a quadrivalent dengue virus vaccine in Asia and Latin America.

Proof of life: Reevaluating oldest known Archean trace fossil for indications of early biology

In the hunt for early life, geobiologists seek evidence of ancient microbes in the form of trace fossils – geological records of biological activity – embedded in lavas beneath the ocean floor. Filamentous titanite (a calcium titanium silicate mineral) microtextures found in 3.45 billion-year-ol... Read More

How U.S. Hospitals Are Planning To Stop The Deadly MERS Virus

In the past month, Middle East Respiratory syndrome has morphed from a little-known disease in the Arabian Peninsula to a major global health concern, with more than 300 cases in Saudi Arabia in April, 54 of them fatal.

Two cases have been reported in the U.S. as well — one in Indiana and one... Read More

The Ebola Outbreak of 2014 2015 A Perfect Storm by Anthony Fauci

Presentation by Anthony S. Fauci, MD, Director, NIAID/NIH, Bethesda, MD, at the ASM Biodefense 2015 Meeting in Washington, D.C. on Feb 11, 2015. Read More

A WORD on the constraints of influenza virus evolution

Evolution proceeds by selection of mutants that arise by error-prone duplication of nucleic acid genomes. It is believed that mutations that are selected in a gene are dependent on those that have preceded them, an effect known as epistasis. Analysis of a sequence of changes in the influenza vir...

Researchers create better methods to detect E. coli

Kansas State University diagnosticians are helping the cattle industry save millions of dollars each year by developing earlier and accurate detection of E. coli.

Lance Noll, master's student in veterinary biomedical science, Greensburg; T.G. Nagaraja, university distinguished professor of di... Read More

The protective milk shot – How mother’s milk protects piglets from parasite infections

Coccidiosis is a serious disease in new-born piglets. Caused by the parasite Cystoisospora suis, it exclusively infects pigs and often causes severe diarrhoea in suckling piglets. Parasitologists at the Vetmeduni Vienna have developed a new strategy for protecting the piglets: They infected sows... Read More

TWiV 309: Ebola email

The TWiVocytes answer questions about Ebola virus, including mode of transmission, quarantine, incubation period, immunity, and much more.

Gut Microbes and Jet Lag, Shift-Work Weight Gain

Disruptions in the human circadian clock can throw off microbes in the gut, potentially boosting the risk of obesity, a new study suggests.

The results may help explain why shift workers and people who get jet lag by traveling frequently often pack on extra pounds.

"These surprising findin... Read More

How E. coli passes safely through stomach acid

In some parts of the world, many small children become infected with severe diarrhea which often proves fatal. The condition is usually caused by strains of Escherichia coli (commonly known as E. coli) bacteria, and bacteria of the genus Yersinia. These bacteria attach themselves to the wall of ... Read More

Bacteria Can't Cling to 'Repulsive' New Surface

Bacteria can’t stick to a new type of nanoscale surface that could prove useful in food processing, medical, and shipping industries.

The technology uses an electrochemical process called anodization to create nanoscale pores that change the electrical charge and surface energy of a metal sur... Read More

When Will We Have a Vaccine for Ebola Virus?

The latest outbreak of Ebola virus in west Africa is the worst ever—as of Monday, it had infected more than 1,200 people and claimed at least 672 victims since this spring. Guinea, Liberia and Sierra Leone all have confirmed cases. An official at Doctors Without Borders has declared the outbreak... Read More

Scientist Finds Link between Antibiotics and Bacterial Biofilm Formation Cause of Chronic Ear, Sinus, and Lung Infections

Researchers from the University of Southern California and the Oak Crest Institute of Science have discovered the link between antibiotics and bacterial biofilm formation leading to chronic lung, sinus and ear infections. The study results, published in the current issue of PLOS ONE, illustrate ... Read More

We Are Our Bacteria

Like ecosystems the world over, the human microbiome is losing its diversity, to the potential detriment of the health of those it inhabits.

Dr. Martin J. Blaser, a specialist in infectious diseases at the New York University School of Medicine and the director of the Human Microbiome Program... Read More

Cyanobacterium found in algae collection holds promise for biotech applications

Cyanobacteria could serve as a synthetic biology chassis that could be retooled for the production of biofuels, drugs or chemcials. So far, however, they have been held back by sluggish growth that makes it difficult to conduct the initial experiments needed to characterize their genetic and met... Read More
