Best of Last Week – speed of light may be wrong, fungus fights resistant bacteria and link between pesticides and autism
Alternating antibiotics render resistant bacteria beatable
Given the alarming rise of antibiotic-resistant bacteria, and the long lead-in time for developing novel drugs, the discovery of new ways to use the antibiotics already available and approved for use in humans is paramount. ...
Bacteria become 'genomic tape recorders'
MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for ap ...
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 ...
Antibiotic effectiveness imperiled as use in livestock expected to increase
Antibiotic consumption in livestock worldwide could rise by 67 percent between 2010 and 2030, and possibly endanger the effectiveness of antimicrobials in humans, according to researchers from Princeton University, ...
A possible alternative to antibiotics
Scientists from the University of Bern have developed a novel substance for the treatment of severe bacterial infections without antibiotics, which would prevent the development of antibiotic resistance.
Chlorine use in sewage treatment could promote antibiotic resistance
Chlorine, a disinfectant commonly used in most wastewater treatment plants, may be failing to completely eliminate pharmaceuticals from wastes. As a result, trace levels of these substances get discharged ...
Tick protein does the trick to fight infection
A protein in ticks that protects them against the cold could inspire a new class of antibiotics for humans, according to a Yale University study.
New antibiotic in mushroom that grows on horse dung
Researchers from the Institute of Microbiology at ETH Zurich have discovered a new protein with antibiotic properties in a mushroom that grows on horse dung. Researchers are now exploring the various potential ...
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.
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 ...
Chemists modify antibiotic to vanquish resistant bacteria
Scientists at The Scripps Research Institute (TSRI) have devised a new antibiotic based on vancomycin that is powerfully effective against vancomycin-resistant strains of MRSA and other disease-causing bacteria.
Synthesis produces new antibiotic: Scientists confirm potent synthesis of natural tetracycline
A fortuitous collaboration at Rice University has led to the total synthesis of a recently discovered natural antibiotic.
Thames study: Rivers can be a source antibiotic resistance
Rivers and streams could be a major source of antibiotic resistance in the environment.
