Effectiveness of ointment that kills antibiotic-resistant bacteria shown
New research shows that use of a topical drug, called AB569, a combination of acidified nitrite and EDTA (or ethylenediaminetetraacetic acid) promotes killing of antibiotic-resistant bacteria while enhancing the healing of wounds in a variety of burn.....»»
Social media for sex education: South African teens explain how it would help them
Most teenagers dread talking about sex with their parents. Their parents feel the same way. In some societies it's considered taboo to even broach the subject. And, even where sexuality education is taught at schools, research has shown that effectiv.....»»
Mobile genetic elements can inadvertently suppress bacterial immune systems, research reveals
Bacterial restriction-modification systems are responsible for protecting cells from foreign genetic material, for example, bacteriophages and plasmids. Immune systems require strict regulation, as bacteria, like humans, can have autoimmune reactions.....»»
Soil bacteria link their life strategies to soil conditions: Study
Soil bacteria help regulate the cycling of carbon and nutrients on Earth. Over time, these bacteria have evolved strategies that determine where they live, what they do, and how they deal with a changing environment. However, microbiologists do not f.....»»
New model finds previous cell division calculations ignore drivers at the molecular scale
When a single bacterial cell divides into two during periods of rapid growth, it doesn't split in half once it reaches a predetermined size. Instead, data has shown, a cell will divide once it has added a certain amount of mass......»»
New class of antimicrobials discovered in soil bacteria
Researchers have discovered toxic protein particles, shaped like umbrellas, that soil bacteria known as Streptomyces secrete to squelch competitors, especially others of their own species......»»
Studying spaceflight atrophy with machine learning
Even intense exercise by astronauts cannot compensate for muscle atrophy caused by microgravity. Atrophy occurs, in part, by way of an underlying mechanism that regulates calcium uptake. Recent research has shown exposure to spaceflight alters the up.....»»
Climate change is wiping out rare bacteria in a "greening" Antarctica
Plenty is known about the existential threat of climate change to plants and animals. But by comparison, we know very little about how microorganisms will be affected by climate change......»»
Disease-resistant strains of carp provide advancements in aquaculture, enhance gefilte fish quality
A new study led by Prof. Lior David from the Faculty of Agriculture at the Hebrew University investigated the infectivity of disease-resistant and susceptible fish by examining their roles as shedders (infecting) and cohabitants (infected) in various.....»»
Improved mid-infrared nanoscopy enables 30 times clearer view of the insides of bacteria
A team at the University of Tokyo have constructed an improved mid-infrared microscope, enabling them to see the structures inside living bacteria at the nanometer scale. Mid-infrared microscopy is typically limited by its low resolution, especially.....»»
Multi-drug resistant bacteria found on International Space Station mutate to become functionally distinct
Principal Investigator Dr. Kasthuri Venkateswaran of NASA's Jet Propulsion Laboratory led a team that studied 13 strains of the bacterial species Enterobacter bugandensis that were isolated from the International Space Station (ISS). E. bugandensis i.....»»
Scientists discover how soil microbes survive in harsh desert environments
Prolonged droughts followed by sudden bursts of rainfall—how do desert soil bacteria manage to survive such harsh conditions? This long-debated question has now been answered by an ERC project led by microbiologist Dagmar Woebken from the Centre fo.....»»
Silver-based micromotors that eliminate bacteria can move freely in aqueous media
Researchers at ICIQ in Tarragona have developed a simple technique to produce microscopic crystals that activate in the presence of light, releasing silver ions with antimicrobial activity......»»
Nanoparticle delivery of FZD4 to lung endothelial cells inhibits lung cancer progression and metastases
A recent study from the lab of Tanya Kalin, MD, Ph.D., professor of Child Health and Internal Medicine at the University of Arizona College of Medicine—Phoenix, has shown potential to improve therapeutic outcomes for patients suffering from lung ca.....»»
Second-biggest black hole in the Milky Way found
May help explain why we see so many of these monsters colliding. Enlarge / The star's orbit, shown here in light, is influenced by the far more massive black hole, indicated by the red orbit. (credit: ESO/L. Calçada) As.....»»
Magnetism boosts hydrogen production in model catalysts
Researchers at the University of Twente have shown how to improve the efficiency of hydrogen production in an experimental setup. They showed that the magnetic order of the molecules plays a critical role......»»
Uranium-immobilizing bacteria in clay rock: Exploring how microorganisms can influence the behavior of radioactive waste
When designing repositories for high-level radioactive waste in deep geological layers, various factors must be carefully considered to ensure their long-term safety. Among other things, natural communities of microorganisms can influence the behavio.....»»
Study suggests real-time feedback in hotel showers could help the tourism industry cut water use
Providing hotel guests with messages about water use while they are taking a shower can reduce the length of time they spend showering by more than 25%, a new study has shown......»»
