Patients getting medical care can catch serious infections called healthcare-associated infections (HAIs). While most types of HAIs... 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

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

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

This Tiny Sensor Spots Salmonella In Minutes, Not Days

A new biosensor quickly detects salmonella in food and can be easily customized to detect other types of bacteria—or even different strains for the same bacterium.

The process appears to easily outperform tests that are now standard in the food industry, according to researchers at Rice Unive... Read More

Key Mechanism Behind Herpes Revealed

Researchers at Lund University in Sweden have for the first time managed to measure the internal pressure that enables the herpes virus to infect cells in the human body. The discovery paves the way for the development of new medicines to combat viral infections. The results indicate good chance... 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

Animating the Inanimate

Concrete is the most widely used building material in the world, with untold amounts being produced yearly. It has always been regarded as a strong, solid, impenetrable, almost indestructible material yet it can make cracks that are vulnerable to penetration by water. As the result, structures ...

Bacteria and hand washing Pragmatic to school children in rural Nepal

Hand washing is thought to be effective for the prevention of transmission of
Diarrhea pathogens. However it is not conclusive that hand washing with soap is more
Effective at reducing contamination with bacteria associated with diarrhea than using water only. 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

Books for the Giving Season: Viral Readings

As the year closes out, we enter into the giving seasons of a variety of traditions.

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

Native algae species to blame for 'rock snot' blooms in rivers worldwide

The recent blooms of the freshwater algae known as "rock snot" on river bottoms worldwide are caused by a native species responding to changing environmental conditions rather than by accidental introductions by fishermen or the emergence of a new genetic strain as widely believed, a Dartmouth C...
