Noxious nanotech: Water-borne nanomaterials promote multidrug-resistance gene transfer
New nanodevice defeats drug resistance
Chemotherapy often shrinks tumors at first, but as cancer cells become resistant to drug treatment, tumors can grow back. A new nanodevice developed by MIT researchers can help overcome that by first blocking ...
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.
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.
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.
Obese father rats have unhealthy daughters
Horizontal gene transfer in microbes much more frequent than previoulsy thought
Researchers identify protein capable of neutralizing antibiotic-resistant bacterial cells
Antibiotic-resistant infections are on the rise, foiling efforts to reduce death rates in developing countries where uncontrolled use of antibiotics and poor sanitation run amok. The epidemic of "superbugs," ...
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.
'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 ...
CRISPR system can promote antibiotic resistance
CRISPR, a system of genes that bacteria use to fend off viruses, is involved in promoting antibiotic resistance in Francisella novicida, a close relative of the bacterium that causes tularemia. The finding contrasts with p ...
