Noxious nanotech: Water-borne nanomaterials promote multidrug-resistance gene transfer
New research could revolutionize genomic sequencing of drug-resistant bacteria
New nanopore DNA sequencing technology on a device the size of a USB stick could be used to diagnose infection - according to new research from the University of East Anglia and Public Health England.
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 ...
Study suggests why, in some species, mere presence of males shortens females' lifespan
Researchers at the Stanford University School of Medicine have discovered that males of the laboratory roundworm secrete signaling molecules that significantly shorten the lifespan of the opposite sex.
Human, soil bacteria swap antibiotic-resistance genes: study
Soil bacteria and bacteria that cause human diseases have recently swapped at least seven antibiotic-resistance genes, researchers at Washington University School of Medicine in St. Louis report Aug. 31 in Science.
Study shows evolutionary adaptations can be reversed, but rarely
(PhysOrg.com) -- Ever since Charles Darwin proposed his theory of evolution in 1859, scientists have wondered whether evolutionary adaptations can be reversed.
With secondhand gene, 'freaky mouse' defeats common poison
Over millennia, mice have thrived despite humanity's efforts to keep them at bay. A Rice University scientist argues some mice have found two ways to achieve a single goal -- resistance to common poison.
Researchers crack the genetic secret of mosquito resistance to DDT and ITNs
Researchers from LSTM have found that a single genetic mutation causes resistance to DDT and pyrethroids (an insecticide class used in mosquito nets). With the continuing rise of resistance the research, published in the ...
Spread of antibiotic resistance understood by unravelling bacterial secretion system
The system that allows the sharing of genetic material between bacteria – and therefore the spread of antibiotic resistance – has been uncovered by a team of scientists at Birkbeck, University of London ...
'Programmable' antibiotic harnesses an enzyme to attack drug-resistant microbes
The multitude of microbes scientists have found populating the human body have good, bad and mostly mysterious implications for our health. But when something goes wrong, we defend ourselves with the undiscriminating ...
Battling superbugs with gene-editing system
In recent years, new strains of bacteria have emerged that resist even the most powerful antibiotics. Each year, these superbugs, including drug-resistant forms of tuberculosis and staphylococcus, infect ...
Overcoming multidrug resistance in cancer cells by silencing genes with RNA
(Phys.org) —Resistance of tumor cells toward multiple cytostatic drugs is a serious problem in cancer treatment. In the journal Angewandte Chemie, a team of Chinese and American researchers has now introd ...
Discovery of essential genes for drug-resistant bacteria reveals new, high-value drug targets
(Phys.org)—Biomedical scientists collaborating on translational research at two Buffalo institutions are reporting the discovery of a novel, and heretofore unrecognized, set of genes essential for the growth ...
