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.....»»
Low-cost phenotyping system unveils key insights into quantitative disease resistance in wild tomatoes
Quantitative disease resistance (QDR) is a complex but durable form of plant disease resistance that provides partial protection against a broad range of pathogens. Unlike qualitative resistance, driven by major resistance (R) genes, QDR is polygenic.....»»
Iron-clad defense: How microbes shield tomato crops from bacterial wilt
Ralstonia solanacearum is a soil-borne pathogen that devastates tomato and other Solanaceae crops globally. Traditional chemical controls have proven inadequate and environmentally damaging......»»
Many physicists argue the universe is fine-tuned for life. Our findings question this idea
Physicists have long grappled with the question of why the universe was able to support the evolution of intelligent life. The values of the many forces and particles, represented by some 30 so-called fundamental constants, all seem to line up perfec.....»»
River microbes near wastewater treatment plants express high levels of antibiotic resistance genes, study shows
Rivers and streams serve as critical connectors across vast geographical landscapes, trickling out of tucked-away headwaters and snaking thousands of miles toward oceans and deep seas. These waterways directly impact human and environmental health, a.....»»
Dinosaur drumsticks, X-ray videos and 3D models shed light on the evolution of bird motion
Wings may be the obvious choice when studying the connection between dinosaurs and birds, but a pair of Yale paleontologists prefer drumsticks. That part of the leg, they say, is where fibular reduction among some dinosaurs tens of millions of years.....»»
Ecologist monitors ecosystem changes as effects of climate change
For the past decade, José Ramírez-Garofalo, a doctoral candidate in the Department of Ecology, Evolution and Natural Resources in the Rutgers School of Environmental and Biological Sciences, has tramped through swamps and meadows in the tri-state m.....»»
Engineered antibiotic D22 shows promise against drug-resistant bacteria
Antibacterial drugs are important for treating infections. But increasingly, bacterial resistance to current drugs—so they don't work well, or even at all—means new ones are urgently needed......»»
Algorithm predicts DNA methylation in ancient specimens, providing insight into human evolution
Research published in Nature Ecology & Evolution introduces a novel method for inferring DNA methylation patterns in non-skeletal tissues from ancient specimens, providing new insights into human evolution. As DNA methylation is a key marker of gene.....»»
First pairs of white dwarf–main sequence binaries discovered in clusters shine new light on stellar evolution
Astronomers at the University of Toronto (U of T) have discovered the first pairs of white dwarf and main sequence stars—"dead" remnants and "living" stars—in young star clusters. Described in a new study published in The Astrophysical Journal, t.....»»
Research reveals even single-cell organisms exhibit habituation, a simple form of learning
A dog learns to sit on command, a person hears and eventually tunes out the hum of a washing machine while reading … The capacity to learn and adapt is central to evolution and, indeed, survival......»»
New giant radio galaxy discovered with MeerKAT
An international team of astronomers has employed the MeerKAT radio telescope to investigate giant radio galaxies in the field of the Cosmological Evolution Survey (COSMOS). They found a new giant radio galaxy that had not been reported before. The f.....»»
How brain evolution is linked to the use of tools
Researchers led by Dr. Alexandros Karakostis from the Institute for Archaeological Science and the Senckenberg Center for Human Evolution and Palaeoenvironment at the University of Tübingen suggest that changes in the brain could have enabled early.....»»
New fossil reveals the evolution of flying reptiles
The pterosaurs are extinct flying reptiles that lived alongside their close relatives, the dinosaurs. The largest of these reached 10 m in wingspan, but early forms were generally limited to around 2 m. In a paper, a team led by paleontologist Dr. Da.....»»
First successful synthesis of elusive antibiotic compounds since their discovery 50 years ago
Back in 1974, German researchers discovered peculiar chemical compounds, present as red pigments in soil bacteria from a volcanic crater. These biomolecules, which came to be known as naphthocyclinones, are representative of a family of antibiotics w.....»»
Transforming code scanning and threat detection with GenAI
In this Help Net Security interview, Stuart McClure, CEO of Qwiet AI, discusses the evolution of code scanning practices, highlighting the shift from reactive fixes to proactive risk management. McClure also shares his perspective on the future of AI.....»»
Scientists propose drug-free method to combat antibiotic-resistant bacteria
Recent estimates indicate that deadly antibiotic-resistant infections will rapidly escalate over the next quarter century. More than 1 million people died from drug-resistant infections each year from 1990 to 2021, a recent study reported, with new p.....»»
The Lucy Fossil’s Extraordinary Journey to Becoming an Icon of Human Evolution
The 3.2-million-year-old human ancestor known as Lucy rose to fame through an incredible combination of circumstances.....»»
Insects Played Pivotal Roles in the Evolution of Human Culture
Violins, the ink on the Declaration of Independence and other ways that insects shaped human history.....»»
The U.S. Must Lead the Global Fight against Superbugs
Antimicrobial resistance could claim 39 million lives by 2050, yet the pipeline for new antibiotics is drying up. U.S. policy makers can help fix it.....»»
Q&A: Holobiont biology, a new concept for exploring how microbiome shapes evolution of visible life
Microorganisms—bacteria, viruses and other tiny life forms—may drive biological variation in visible life as much, if not more, than genetic mutations, creating new lineages and even new species of animals and plants, according to Seth Bordenstei.....»»
