Superbugs
-
Bacteria are fast developing resistance to our antibiotics, potentially ushering in a new “dark age of medicine” where basic infections become lethal again. Now scientists have developed self-assembling “nanonets” that can trap and kill superbugs.
-
Bacteria are fast developing resistance to our best drugs, leaving us poised on the edge of a major health crisis. But a new antibiotic has shown promise against several key “superbugs,” while minimizing damage against good bacteria in the body.
-
Bacteria are great at resisting antibiotics, but they can’t fight tiny drills ripping them open. Researchers have now demonstrated next-generation molecular drills that are activated by blue light and could revolutionize the fight against superbugs.
-
Antibiotic-resistant bacteria are poised to become a major health problem, predicted to claim up to 10 million lives a year by 2050. Researchers have found a new way to fight back, by targeting a protein that bacteria use to generate drug resistance.
-
Failing antibiotics could lead to a future “dark age of medicine” where once-simple infections become lethal again. Scientists have now found a way to restore antibiotics to their former strength, by repurposing a drug developed to treat Alzheimer’s.
-
In a significant breakthrough, scientists have pinpointed signs of "pre-resistance" in bacteria for the first time, which they say could allow for better targeted therapies that nip superbugs in the bud before they develop resistance to drugs.
-
Modern medicine is locked in an arms race against antibiotic-resistant “superbugs.” A new treatment may give us the upper hand again by knocking out enzymes that bacteria use to defend themselves against the drugs.
-
Antibiotics were one of the most important inventions of the 20th century, but bacteria are developing resistance to them. Now researchers have shown that ultrashort pulses of laser light can kill bacteria and viruses, without harming human cells.
-
Scientists may have found a way to re-enlist old antibiotics in the fight against superbugs. Gold nanoparticles were wrapped in molecules that seek out bacteria and disrupt their cell membranes, allowing existing drugs to kill them easier.
-
Antibiotic-resistant bacteria are poised to become a major health threat in the coming decades – but new antibiotics may have been inside us all along. A search algorithm has discovered dozens of potential antimicrobial peptides in the human body.
-
By using a nanoscale needle tip to probe the intricate exterior structures of Escherichia coli, scientists have produced the sharpest images ever of living bacteria, which may help us better understand the growing problem of antibiotic-resistant superbugs.
-
Scientists have demonstrated a new way to fight antibiotic-resistant superbugs by pitting bacteria against each other. The team engineered a common bacteria to safely colonize medical implants, then produce enzymes that dissolve superbug biofilms.
