Urban Birds Are Harboring Antibiotic-Resistant Bacteria
Exposure to bacteria in landfill sites and polluted rivers may explain prevalence among city-dwelling birds......»»
Ultra-high speed camera for molecules: Attosecond spectroscopy captures electron transfer dynamics
In nature, photosynthesis powers plants and bacteria; within solar panels, photovoltaics transform light into electric energy. These processes are driven by electronic motion and imply charge transfer at the molecular level. The redistribution of ele.....»»
Cloud cover and urban structures drastically reduce sunlight in cities
Sunlight plays a crucial role in public health, affecting vitamin D synthesis and psychological well-being. Inadequate exposure to sunlight is associated with various adverse health outcomes, such as cardiovascular diseases, metabolic syndrome, depre.....»»
"Palm-sized birds" extinct in the wild since 1988 make "monumental" return to island
It's been 35 years since this "cerulean blue and cinnamon" colored bird has flown free in the wild......»»
Naked mole-rat found to have lost infection-resistant proteins
Scientists have found that the naked mole-rat—an underground rodent that lives up to 40 years—has lost a number of CD1 functional genes. The CD1 gene family in mammals is responsible for protein synthesis that protects the body against infectious.....»»
Better together: Gut microbiome communities found to have enhanced resilience to drugs
Many human medications can directly inhibit the growth and alter the function of the bacteria that constitute our gut microbiome. EMBL Heidelberg researchers have now discovered that this effect is reduced when bacteria form communities......»»
Graphene spike mat uses ordinary fridge magnet tech to fight antibiotic resistance
With strong bactericidal properties, graphene has the potential to become a game changer in the fight against antibiotic-resistant bacteria. So far there have been no efficient ways to control these properties—and thus no way to make use of graphen.....»»
Potential breakthrough in battle against antibiotic resistance from historic brine
A historic brine bath is the site of a potential breakthrough in the prevention of antibiotic resistance in relation to MRSA, and other hospital pathogens......»»
Traces of 10 common pharmaceuticals detected in corals in the Gulf of Eilat
A new study from Tel Aviv University and the Steinhardt Museum of Natural History detected traces of 10 common medications in coral samples collected from both shallow and deep sites in the Gulf of Eilat. Sulfamethoxazole, an antibiotic used for resp.....»»
Indigenous outback rangers in WA find up to 50 night parrots, among Australia"s most elusive birds
In arid inland Australia lives one of Australia's rarest birds: the night parrot. Missing for more than a century, a live population was rediscovered in 2013. But the species remains elusive......»»
Chemists discover new ways in which single-celled organisms organize their DNA
It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones—proteins that structure DNA. Now, Leiden Ph.D. candidate Samuel Schwab has found that the histones in these organisms are much more diverse.....»»
Experts discover the deadly genetics of cholera, which could be key to its prevention
Experts have used a cutting-edge computational approach to discover the genetic factors that make the bacteria behind cholera so dangerous—which could be key to preventing this deadly disease......»»
"Pirate birds" force other seabirds to regurgitate fish meals. Their thieving ways could spread lethal avian flu
It's not easy finding food at sea. Seabirds often stay aloft, scanning the churning waters for elusive prey. Most seabirds take fish, squid, or other prey from the first few meters of seawater. Scavenging is common......»»
AI tools help uncover enzyme mechanisms for lasso peptides
Lasso peptides are natural products made by bacteria. Their unusual lasso shape endows them with remarkable stability, protecting them from extreme conditions. In a new study, published in Nature Chemical Biology, researchers have constructed and tes.....»»
How a bacterial pathogen that causes dysentery manipulates molecular activity to assure its survival
Virginia Tech researchers have learned how bacteria manipulate molecules to infect the host organism. Daniel Capelluto and his research team have discovered the mechanism by which the bacterial pathogen Shigella flexneri, the causative agent of dysen.....»»
Greylag geese with similar personalities have higher hatching success, study suggests
Birds of a feather flock together but strong pairing in geese has been shown to produce better breeding results, according to a new study......»»
Plant pathogen battle: A tomato protein"s dual role in defense and susceptibility
Tomatoes, a staple crop worldwide, are increasingly threatened by biotic stressors such as viruses, fungi, and bacteria, with the effects worsening under climate change. These challenges lead to reduced yields and compromised nutritional quality, hig.....»»
Harmless strain of E. coli bacteria may be able to prevent urinary tract infections
Researchers from the Texas A&M College of Veterinary Medicine and Biomedical Sciences (VMBS) and the College of Engineering are collaborating on a project that uses harmless strains of E. coli bacteria to disrupt the bacteria responsible for urinary.....»»
Scientists identify 18 bacterial strains to treat antibiotic-resistant gut infections
Antibiotic-resistant bacterial infections often occur in patients with chronic inflammatory intestinal conditions, such as inflammatory bowel disease, and in patients who have taken antibiotics for a long time. Gram-negative bacteria such as Enteroba.....»»
Scientists quantify energetic costs of the migratory lifestyle in a free flying songbird
Millions of birds migrate every year to escape winter, but spending time in a warmer climate does not save them energy, according to research by the Max Planck Institute of Animal Behavior (MPI-AB). Using miniaturized loggers implanted in wild blackb.....»»
Slow-moving landslides a growing, but ignored, threat to mountain communities
As urban centers in mountainous regions grow, more people are driven to build on steeper slopes prone to slow-moving landslides, a new study finds. Slow-moving landslides are frequently excluded from estimates of landslide risk, but they could threat.....»»
