Diversity in typhoid bacteria linked to higher mortality rates
Worldwide, 20% of the bacterial strains that cause typhoid fever have genetic variations in their external layer, called Vi capsule, that provide higher virulence, higher infectivity and high antibiotic resistance, Cornell researchers have discovered.....»»
Accurately weighing costs and benefits of different methods for controlling invasive species
Invasive insect species bring a host of health, social, ecological and economic consequences, including crop damage, food insecurity, biodiversity loss, ecosystem disruption, human disease transmission and rising allergy rates......»»
Unexpected beauty and major antimicrobial power boost as phages form into surprising flower shapes
A group of McMaster researchers who routinely work with bacteriophages—viruses that eat bacteria—had a pleasant and potentially very important surprise while preparing slides to view under a powerful microscope......»»
Nitrogen-fixing plant diversity declines with over-fertilization, study finds
Anthropogenic nitrogen deposition and climate change can reduce the competitive advantage of nitrogen-fixing plants, leading to reduced diversity of these plants in a community. Surprisingly, changes in temperature and aridity do not contribute to th.....»»
Owners" belief in horse emotion is linked to healthier animals, new study shows
Researchers have shown that owners who believe in their horses' emotions and treat them with care, have animals that are significantly healthier and better looked after. In many low and middle-income countries (LMICs), working horses are essential to.....»»
"Nano-weapon" discovery boosts fight against antibiotic-resistant hospital superbugs
Researchers have discovered how a bacteria found in hospitals uses "nano-weapons" to enable their spread, unlocking new clues in the fight against antibiotic-resistant superbugs......»»
Chemical trick activates antibiotic directly at the pathogen
Colistin is a last-resort antibiotic that is usually only used for severe infections with resistant bacteria. This is due to its severe kidney-damaging side effects, which occur in about 30% of treated patients. A research team at the Helmholtz Cente.....»»
Study evaluates overall soil arthropod diversity at different geographic scales
Soil arthropods contribute to terrestrial ecosystem functions and services. Previous studies have mainly focused on specific arthropod and non-arthropod taxonomic groups at various geographic scales. However, the patterns of overall soil arthropod co.....»»
Butterfly brains reveal the tweaks required for cognitive innovation
A species of tropical butterfly with unusually expanded brain structures displays a fascinating mosaic pattern of neural expansion linked to a cognitive innovation......»»
Materials of the future can be extracted from wastewater
A group of researchers is on the way to revolutionizing what biomass from wastewater treatment plants can be used for. Biopolymers from bacteria can be a sustainable alternative to oil-based products, and phosphorus and other minerals can also be har.....»»
Research finds 1.1 billion people in multidimensional poverty, with nearly a half-billion in conflict settings
New research from the United Nations Development Program (UNDP) and the Oxford Poverty and Human Development Initiative (OPHI) has found that poverty rates in conflict-affected nations are almost three times higher than in countries free from conflic.....»»
Single-molecule imaging reveals aberrant DNA-binding dynamics of cancer-linked chromatin remodelers
Biophysical chemists from the National University of Singapore (NUS) have uncovered a previously hidden landscape that governs the intracellular organization and dynamics of SWI/SNF chromatin remodelers, an important class of protein complexes that c.....»»

US vaccinations fall again as more parents refuse lifesaving shots for kids
US becomes more vulnerable to outbreaks at vaccination rates fall into 92 percent range. Measles, whopping cough, polio, tetanus—devastating and sometimes deadly diseases await.....»»
Resolving biology"s dark matter: DNA barcoding reveals hidden insect diversity
There are millions of species on Earth that we still know nothing about. Researchers call these species "biological dark matter," but new methods can provide us with a better overview more quickly......»»
Hyundai internship hopes to accelerate automotive media diversity
HBCU students at Florida A&M gain hands-on experience and networking opportunities to break into the automotive industry......»»
A method to switch between optical pulling and pushing forces by altering the shape of Fermi arcs in Weyl systems
Optical forces, which act like an invisible "hand," are capable of precisely controlling tiny particles. Optical tweezers, a well-known tool, use this force to capture and manipulate small objects such as cells, bacteria, and viruses. This effect is.....»»
Biofilms study reveals how multiple bacteria species manage to coexist
Biofilms—slimy communities of bacteria—grow on all sorts of surfaces: from glaciers and hot springs to plant roots, your bathtub and fridge, wounds, and medical devices such as catheters. Most biofilms are composed of multiple bacterial species,.....»»
Catching prey with grappling hooks and cannons: The unusual weapons arsenal of a predatory marine bacterium
Countless bacteria call the vastness of the oceans home, and they all face the same problem: the nutrients they need to grow and multiply are scarce and unevenly distributed in the waters around them. In some spots they are present in abundance, but.....»»
Pathogenic system found on Providencia rustigianii has virulence gene akin to Salmonella"s
Salmonella and E. coli are well-known bacteria that cause food poisoning, but less understood are species of Providencia, another causative agent of serious symptoms......»»
Higher oxytocin levels linked to reproductive success and better cooperation in house mice
Researchers have further advanced understanding of social relationships in female mammals, highlighting the critical role oxytocin plays......»»
