Innocence by Viral Tagging - Finalist in Ocean 180 Video Challenge

Viruses are the most abundant biological entities on the planet with approximately 1030 in the world’s oceans at any time. As such, they play a central role in global nutrient cycling. Despite their ecological importance, little is known about how viruses interact with their hosts due to the dif... Read More

New research from Africa on pharmacomicrobiomics

The Human Microbiome Project (HMP) is a global initiative to identify and characterize the microorganisms present at multiple sites in the human body. An international team of researchers reports on new ways to harness the results of the HMP and discusses how changes in the microbiome might affe... Read More

Gut Bacteria in Preemies Altered by Hospital Stay, Study Finds

Gut bacteria in premature infants don't come from their mothers, but from microbes in the neonatal intensive-care unit (NICU), a new study finds. Babies typically get their gut bacteria from their mothers during childbirth. Premature infants, however, receive antibiotics during their first week ... Read More

New genomics technique could improve treatment and control of malaria

Single-cell genomics could provide new insight into the biology of malaria parasites (including their virulence and levels of drug resistance) to ultimately improve treatment and control of the disease, according to new research funded by the Wellcome Trust and the National Institutes of Health....

Infectious diseases: Smallpox watch

In 2011, while construction workers were digging a foundation at a site in Queens, New York, their equipment struck against something metal. Then a body rolled out of the rubble. Thinking that they might have unearthed the shallow grave of a murder victim, the workers immediately called the New ... Read More

Saudi Arabia reports 1 more death from new virus

Saudi Arabia says one more person has died from a new respiratory virus related to SARS, bringing to 55 the number of deaths in the kingdom at the center of the outbreak.

How Clean Should We Be?

There's a belief that says exposing people -- especially babies and young children -- to different kinds of germs early in life can keep them from developing illnesses like asthma, allergies, and other diseases that affect the immune system. The theory, called the “hygiene hypothesis,” is that o... Read More

Physarum oblatum

Myxomycetes are well-known as true slime molds whose plasmodia are increadibly beautiful. Plasmodial culture is a such kind of hard-working steps in working with the species of Kingdom Protista. Interestingly, they can unpredictably "move" around water agar dishes. Furthermore, they are in progr... Read More

The role of uncertainty in infectious disease modelling

The study found that many models provided only cursory reference to the uncertainties of the information and data, or the parameters used

Research by scientists at the University of Liverpool has found that greater consideration of the limitations and uncertainties in infectious disease model... Read More

Good C-DIFF Agents May Keep Our Homeland Safe

Rogue agents always add a thrilling plot twist in any spy television show, movie or Tom Clancy novel. The devastating impact these evildoers have on the world increases suspense and concern for the characters -- and bystanders -- who may become victims. Inevitably, it is up to those who strive f...

Who's Protecting Whom From Deadly Toxin?

Questions are swirling around a science journal's decision last year to publish a description of a newly discovered botulinum toxin while omitting key genetic details that researchers would normally disclose. The unusual case highlights important unresolved issues in how to balance scientific op... Read More

Books for the Giving Season: Viral Readings

As the year closes out, we enter into the giving seasons of a variety of traditions. Lurking among the more pleasant types of giving is the 2013 – 2014 flu season, a viral gift that often keeps on giving. To combat this, reminders about the potential dangers of influenza and the importance of va... Read More

Herbivore drool defeats fungal defence

A report in Biology Letters shows that the drool of herbivores might help defeat the toxic fungal defences of the plants they graze on.

Grazing or cutting some plants induces a noxious chemical to be produced which deters hungry plant-eaters from revisiting them. The chemicals, called alkaloi... Read More

Pictures Considered #17. The Meselson-Stahl Experiment

Described as the “Most Beautiful Experiment In Biology” the demonstration by Meselson and Stahl that DNA replicates semiconservatively is one of the major landmarks in the genesis of modern biology. And indeed it is most pleasing, both visually and cerebrally.

By semiconservative is meant tha... Read More

A Bacterial Body Clock: Cryptic Periodic Reversals In Paenibacillus dendritiformis

As humans we live our lives in 24-hour increments—waking, eating, and sleeping at specific times dictated to us not solely by our discerning willpower, but also by the greater underlying persuasion of our circadian rhythm. Based on the earth’s rotation from day into night, we have internalized a... Read More

Designer 'Swiss-Army-Knife' Molecule Captures RNA from Single Cells in Their Natural Tissue Environment

A multi-disciplinary team from the University of Pennsylvania have published in Nature Methods a first-of-its-kind way to isolate RNA from live cells in their natural tissue microenvironment without damaging nearby cells. This allows the researchers to analyze how cell-to-cell chemical connectio... Read More

Predictive model a step toward using bacteria as a renewable fuel source

A new transcriptomics-based model accurately predicts how much isoprene the bacterium Bacillus subtilis will produce when stressed or nourished. This model marks a step toward understanding how changes in the bacteria's environment affect gene expression and, in turn, isoprene production. Isopre... Read More
