New molecule found to suppress bacterial antibiotic resistance evolution
Researchers from the University of Oxford have developed a new small molecule that can suppress the evolution of antibiotic resistance in bacteria and make resistant bacteria more susceptible to antibiotics. The paper, "Development of an inhibitor of.....»»
A high-temperature superconductor with zero resistance that exhibits strange metal behavior
Researchers at Zhejiang University and Sun Yat-Sen University have gathered evidence of high-temperature superconductivity with zero resistance and strange metal behavior in a material identified in their previous studies......»»
Global South health care practices contribute to spread of antimicrobial resistance across the world, study suggests
Many bacteria resistant to multiple antibiotics originate in Pakistan and other parts of the Indian subcontinent. Infections caused by these bacteria are challenging to treat; longer treatment with broad-spectrum antibiotics is required and despite t.....»»
Hidden mechanisms behind hermaphroditic plant self-incompatibility revealed
A new study presents an evolutionary-biophysical model that sheds new light on the evolution of the collaborative non-self recognition self-incompatibility, a genetic mechanism in plants that prevents self-fertilization and promotes cross-fertilizati.....»»
Astronomers study evolution of a giant outburst in X-ray binary EXO 2030+375
An international team of astronomers has observed an X-ray binary system known as EXO 2030+375. Results of the observation campaign, presented in a research paper published June 18 on the pre-print server arXiv, provide more insights into the evoluti.....»»
How "sticky" is dense nuclear matter?
Colliding heavy atomic nuclei together creates a fluidlike soup of visible matter's fundamental building blocks, quarks and gluons. This soup has very low viscosity—a measure of its "stickiness," or resistance to flow......»»
Researchers develop RNA-targeting technology for precisely manipulating parts of human genes
Researchers at the University of Toronto have harnessed a bacterial immune defense system, known as CRISPR, to efficiently and precisely control the process of RNA splicing. The technology opens the door to new applications, including systematically.....»»
Blooming through adversity: Roses" genetic defense against salinity stress
A cutting-edge study illuminates the intricate mechanisms of rose plants' resistance to salt stress, a critical issue for global agriculture. The research identifies the phenylpropane pathway, especially flavonoids, as key to this tolerance, offering.....»»
How E. coli defends itself against antibiotics
Imagine that you have a very sore throat. You're sick, your throat hurts, and a visit to the doctor confirms that the pain is due to a bacterial infection. You get a prescription for antibiotics, which quickly sorts out your sore throat. You are plea.....»»
Many more bacteria produce greenhouse gases than previously thought, study finds
Caltech researchers have discovered a new class of enzymes that enable a myriad of bacteria to "breathe" nitrate when in low-oxygen conditions. While this is an evolutionary advantage for bacterial survival, the process produces the greenhouse gas ni.....»»
Inspired by nature: Synthetic nightshade molecule effective against leukemia cells
Nightshade plants produce a diverse array of compounds with therapeutic potential. Researchers at CeMM have now identified an artificial variant inspired by the Withanolides group that acts highly specifically against leukemia cells......»»
Antibiotic-resistance in sub-Saharan Africa "alarming": Studies
Superbug infections are taking a disproportionate toll in sub-Saharan Africa where there is "extremely concerning" levels of multi-resistant bacterial strains among young children, two studies warned Thursday......»»
Using soil bacteria to help accelerate discovery of new antibiotics
Northeastern researcher Kim Lewis is spearheading an effort to accelerate discovery of new antibiotics as part of a multi-institutional project to tackle the growing problem of antibiotic resistance......»»
Old drugs new tricks—novel approach shows "enormous potential" for rapid antibiotic discovery
An innovative project to re-purpose existing drugs for their potential as antibiotics has uncovered a highly promising candidate with a potent and unique way of killing drug resistant bacteria......»»
How glacier algae are challenging the way we think about evolution
People often underestimate tiny beings. But microscopic algal cells not only evolved to thrive in one of the most extreme habitats on Earth—glaciers—but are also shaping them......»»
Earth"s atmosphere is our best defense against nearby supernovae, study suggests
Earth's protective atmosphere has sheltered life for billions of years, creating a haven where evolution produced complex lifeforms like us. The ozone layer plays a critical role in shielding the biosphere from deadly UV radiation. It blocks 99% of t.....»»
Investigating nematode-microbe interactions in lab-simulated decomposed beetle environments
Beneath the surface, bacterivorous nematodes are key players in the nutrient cycle, consuming bacteria that decompose organic matter. Traditionally, these nematodes are studied in laboratory environments where isolated bacterial strains are used to m.....»»
Ultraviolet-absorbing film shows promise in controlling insecticide-resistant thrips in Chinese agriculture
A research team has found that field populations of the thrips Megalurothrips usitatus and Thrips palmi in China have developed high resistance to multiple insecticides, presenting significant control challenges. By utilizing ultraviolet-absorbing fi.....»»
Researchers reveal influence of cyclic dynamic disturbance on coal-rock evolution and zoning
In coal-rock formations, many micro-fractures exist, and the expansion of these micro-fractures is the internal catalyst for the macroscopic destruction of coal-rock. Moreover, the occurrence state of gas changes with the expansion of micro-fractures.....»»
Searching for a female partner for the world"s "loneliest" plant
"Surely this is the most solitary organism in the world," wrote paleontologist Richard Fortey in his book about the evolution of life......»»
Saturday Citations: Bacterial warfare, a self-programming language model, passive cooling in the big city
There's a lot of science news in seven days, so just because a new study isn't cited here on Saturday morning doesn't mean it didn't happen. A lot more has happened. But also, check out these four stories:.....»»
