Bacterial protein called UmuD may prevent antibiotic resistance
The widespread and indiscriminate use of antibiotics has prompted many bacteria to mutate, an adaptation that often renders the drugs useless. The increasing threat of resistance worries infectious disease ...
Mobile DNA sequencer shows potential for disease surveillance
A pocket-sized device that can rapidly determine the sequence of an organism's DNA has shown its potential in disease detection, according to a study published in the open access, open data journal GigaScience.
Bacteria can use magnetic particles to create 'natural battery'
New research shows bacteria can use tiny magnetic particles to effectively create a 'natural battery.' According to study published in journal Science on 27 March, the bacteria can load electrons onto and discharge electr ...
Researchers shed light on how 'microbial dark matter' might cause disease
One of the great recent discoveries in modern biology was that the human body contains 10 times more bacterial cells than human cells. But much of that bacteria is still a puzzle to scientists.
Origin of the Eukaryotic cell: Part II - Cytoskeleton, membranes, and beyond
Wireless electronic implants stop staph, then dissolve
Researchers at Tufts University, in collaboration with a team at the University of Illinois at Champaign-Urbana, have demonstrated a resorbable electronic implant that eliminated bacterial infection in mice ...
First detailed microscopy evidence of bacteria at the lower size limit of life
Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The research was led by scientists from the U.S. Department of ...
Researchers survey microbes that influence plant health
When driving past a sunlit field of grapes, we miss the frenzy of activity that is invisible to the human eye. Vines and roots teem with bacteria, and viruses and fungi all impact how those grapes will grow.
Bacteria play important role in long term storage of carbon in ocean
The ocean is a large reservoir of dissolved organic molecules, and many of these molecules are stable against microbial utilization for hundreds to thousands of years. They contain a similar amount of carbon ...
Researchers find bubonic plague fragments on NY subway
It is universally acknowledged that the New York subway is grubby. What may come as a shock is that it contains DNA fragments linked to anthrax and bubonic plague.
Researchers unravel secrets of shape-shifting bacteria
Sixty years ago, Nobel Prize-winning scientist Joshua Lederberg first described a biological mystery. He showed how bacteria could lose the cell walls that define their shapes, potentially becoming less visible ...
Antibiotic resistance risk for coastal water users
Recreational users of coastal waters such as swimmers and surfers are at risk of exposure to antibiotic resistant bacteria, according to new research published this week.
Micro-5: Gut reactions in space
Our guts literally teem with beneficial bacteria. But not all bacteria are harmless. Disease-causing bacteria, known as pathogens, can infect our intestines, causing illness or even death. Bacterial pathogens ...
Team discovers evolutionary mechanism that allows bacteria to resist antibiotics
In research published in Proceedings of the National Academy of Sciences, assistant professor of biochemistry and molecular biology at Saint Louis University Mee-Ngan F. Yap, Ph.D., discovered new inform ...
