How bacteria cope with stress
When exposed to stress, bacteria allow their metabolism to take a break during which they suppress, for example, the incorporation of proteins into membranes. Scientists from Marburg, Freiburg and Munich have discovered this by biochemically investig.....»»
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.....»»
Discovery of 2,586 orphan genes in Rosa chinensis reveals stress adaptation and flower development
Orphan genes, found only in specific lineages, are key drivers of new functions and phenotypic traits. This discovery lays a foundation for understanding how roses thrive under environmental challenges......»»
Election Grief Is Real. Here’s How to Cope
Understanding the psychology of ambiguous loss can help people struggling with grief and depression in the wake of the 2024 election results.....»»
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.....»»
Financial anxiety leads to unnecessary Christmas shopping, say researchers
Christmas is approaching, and for many, economic stress is increasing. Paradoxically, this can lead us to purchase even more gifts. Recent research from the University of Skövde shows that financial anxiety and stress trigger impulsive buying. The.....»»
Scientists reveal strigolactone perception mechanism and role in tillering responses to nitrogen
"How is plant growth controlled?" and "What is the basis of variation in stress tolerance in plants?" were among the 125 most challenging scientific questions, according to the journal Science in 2016......»»
Making "stressed" potatoes more climate-resilient
Heat, dry spells and flooding—the whole of nature is under stress, and potatoes are no exception. As a food staple, there is particular interest in getting potatoes fit for the new climate reality. As part of the EU's four-year ADAPT project, an in.....»»
Sensitive yet empathetic: The dual nature of highly sensitive persons in the workplace
Work stress is a prevalent issue globally, and a recent study from Japan highlights a distinct group of employees who perceive stress in a unique way. Highly sensitive persons (HSPs), known for their heightened sensitivities to external stimuli, tend.....»»
Spraying rice with zinc oxide nanoparticles protects yields during heat waves, study finds
A small team of horticulturists in China and the U.S. has found that spraying rice plants with a zinc oxide nanoparticle solution helps them better handle the stress of a heat wave. In their study, published in Proceedings of the National Academy of.....»»
Bacteria discovery could accelerate mosquito control schemes
Mosquito larvae grow faster if they're exposed to particular bacteria, according to a new study that could help global health programs......»»

Here are 3 science-backed strategies to rein in election anxiety
A clinical psychologist offers guidance on how to deal with ramping stress. Uncertainty about the election getting to you? Is anxiety the dominant feature of your emotional lands.....»»
Human histones show promise in fighting bacterial infections
Antibiotics have saved millions of lives from infectious diseases and are considered one of the most important discoveries of the 20th century. However, as the use (and abuse) of antibiotics has increased over the years, many bacteria have developed.....»»
Using machine learning to identify bacterial resistance genes and the drugs to block them
Antibiotic resistance is a growing public health problem around the world. When bacteria like E. coli no longer respond to antibiotics, infections become harder to treat......»»
Researchers reveal key findings from national voter opinion survey on the economy and political stress
Researchers at the University of South Florida have released findings from a nationwide survey that measures attitudes related to several key election issues. The survey, sponsored by Cyber Florida at USF, addresses how Americans feel about topics in.....»»
Pivotal gene found to confer heat tolerance in perennial ryegrass
Perennial ryegrass (Lolium perenne L.), widely cultivated in the cool-season for forage supply and turfgrass, is extremely susceptible to high temperatures. A recent study has discovered a pivotal stress-responsive gene, combating heat stress in pere.....»»
Coral exudates, not algae, linked to bacterial growth that threaten reefs
A study led by the University of Bremen suggests that on algae-dominated coral reefs, it is not the algae but the corals themselves that may contribute to the growth of harmful bacteria. This discovery suggests that a disturbance in the natural compo.....»»
New gold nanorod technology can fry bacteria to sterilize implants
In the fight against antibiotic resistance, a new technology developed at Chalmers University of Technology, in Sweden, can be of great importance when, for example, hip and knee implants are surgically inserted. By heating up small nanorods of gold.....»»
Investigating the flow of fluids with non-monotonic, "S-shaped" rheology
Water and oil, and some other simple fluids, respond in the same way to all levels of shear stress. These are termed Newtonian fluids, and their viscosity is constant for all stresses although it will vary with temperature. Under different stresses a.....»»
New class of encrypted peptides exhibits significant antimicrobial properties
In a significant advance against the growing threat of antibiotic-resistant bacteria, researchers have identified a novel class of antimicrobial agents known as encrypted peptides, which may expand the immune system's arsenal of tools to fight infect.....»»
