Noxious nanotech: Water-borne nanomaterials promote multidrug-resistance gene transfer
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
Quantitative approaches provide new perspective on development of antibiotic resistance
Using quantitative models of bacterial growth, a team of UC San Diego biophysicists has discovered the bizarre way by which antibiotic resistance allows bacteria to multiply in the presence of antibiotics, a growing health ...
Scientists help deliver genetic one-two blow to deadly wheat disease
(Phys.org) —A new gene that will equip wheat plants to resist the deadly stem rust disease has been discovered by an international team that includes plant scientists at the University of California, Davis.
Geneticists show COPIA-R7 transposon enhances immunity of its host against pathogenic microorganism
(Phys.org) —Transposons are DNA elements that can multiply and change their location within an organism's genome. Discovered in the 1940s, for years they were thought to be unimportant and were called "junk ...
Resistance gene found against Ug99 wheat stem rust pathogen
The world's food supply got a little more plentiful thanks to a scientific breakthrough. Eduard Akhunov, associate professor of plant pathology at Kansas State University, and his colleague, Jorge Dubcovsky from the University ...
Biotech crops vs. pests: Successes and failures from the first billion acres (Update)
Since 1996, farmers worldwide have planted more than a billion acres (400 million hectares) of genetically modified corn and cotton that produce insecticidal proteins from the bacterium Bacillus thuringiensis, or Bt ...
Bacteria evolve resistance more quickly when stronger antibiotics are used
New scientific research published today in the journal PLoS Biology shows that bacteria can evolve resistance more quickly when stronger antibiotics are used.
Fighting disease from within the mosquito: New techniques to help halt the spread of disease
(Phys.org) —Scientists have revealed a new technique to introduce disease-blocking bacteria into mosquitoes, with promising results that may halt the spread of diseases such as dengue, yellow fever and ...
