Chemical cocktail in skin summons disease-spreading mosquitoes
Mosquitoes that spread Zika, dengue and yellow fever are guided toward their victims by a scent from human skin. The exact composition of that scent has not been identified until now......»»
Honey bees may play key role in spreading viruses to wild bumble bees
Honey bees may play a role in increasing virus levels in wild bumble bees each spring, according to researchers at Penn State who analyzed seasonal trends of parasite and virus transmission in bees......»»
Scientists help turn whisky waste into valuable commodity
A new method to extract valuable bio-based chemicals from whisky distillery waste streams could transform manufacturing and be worth up to £90 million in global chemical manufacturing markets......»»
Tissue fluidization during skin repair is crucial for wound healing, study reveals
The ability to repair tissue following injuries is essential for the survival of all animals. Following wounding, the skin is repaired by activating, migrating, and dividing skin stem cells. Defects of wound healing in humans lead to chronic wounds t.....»»
First visualization of valence electrons reveals fundamental nature of chemical bonding
The distribution of outermost shell electrons, known as valence electrons, of organic molecules was experimentally observed for the first time by a team led by Nagoya University in Japan. As the interactions between atoms are governed by the valence.....»»
Study finds "DNA scavengers" can stop some antibiotic resistance from spreading
For nearly a century, scientists have waged war on antibiotic-resistant microbes. Michigan State University researchers say they've found a new way to prevent it—by unleashing "DNA scavengers" in wastewater treatment plants......»»
Proteins for skin strength also control cell signaling, study suggests
An extensive family of proteins that gives human skin mechanical strength also appears to organize molecular signals that control skin cell activity, a study led by UT Southwestern Medical Center researchers shows. The team's findings, published in D.....»»
Cellular DNA damage response pathways might be useful against some disease-causing viruses
New research reveals that triggering a cell's DNA damage response could be a promising avenue for developing novel treatments against several rare but devastating viruses for which no antiviral treatments exist, possibly including human papilloma vir.....»»
Study discovers an electric current in the gut that attracts pathogens like Salmonella
How do bad bacteria find entry points in the body to cause infection? This question is fundamental for infectious disease experts and people who study bacteria. Harmful pathogens, like Salmonella, find their way through a complex gut system where the.....»»
Cleanup hopes for neighbors of Mexico"s "toilet bowl" wastewater dam
On the banks of a wastewater dam in central Mexico, under a dense cloud of mosquitoes, Yury Uribe is finally seeing hope after spending decades in "environmental hell.".....»»
Roundworm study paves way for better RNA-based drugs to treat human disease
RNA interference (RNAi) therapeutics have garnered significant attention in clinical research due to their potential for treating various diseases, including genetic disorders, viral infections and cancer. These therapeutics can target and silence di.....»»
Mosquitoes use gut bacteria to fight the malaria they transmit—scientists are exploring how to use this
The months of September to May are an unfortunate season in South Africa: malaria season. The mosquito-borne disease is found in the north-eastern districts of KwaZulu-Natal, Mpumalanga and Limpopo provinces......»»
Experts study immigration in relation to jobs, crime and disease
According to the U.S. Census Bureau, immigrants made up 13.9% of the total population in 2022. Among them are highly skilled workers who fill critical gaps in high-tech industries as well as those who construct the buildings in which we live and who.....»»
AI accelerates discovery of next-gen polymers
Nylon, Teflon, Kevlar. These are just a few familiar polymers—large-molecule chemical compounds—that have changed the world. From Teflon-coated frying pans to 3D printing, polymers are vital to creating the systems that make the world function be.....»»
New forensics technique measures individual DNA shedding to aid criminal investigations
A pioneering new DNA forensics technique is looking for a reliable method to measure a suspect's individual level of natural shedding of skin and other cells to add to, and compare with, evidence collected at crime scenes......»»
Pioneering research discovers PFOS chemical pollution in platypuses
Research from Western Sydney University has discovered PFOS (perfluorooctane sulfonate) chemical contamination in the livers of deceased platypuses across eastern New South Wales......»»
New software tool aims to reduce reliance on animal testing
In recent years, machine learning models have become increasingly popular for risk assessment of chemical compounds. However, they are often considered "black boxes" due to their lack of transparency, leading to skepticism among toxicologists and reg.....»»
A new reaction to enhance aromatic ketone use in chemical synthesis
Aromatic ketones have long been valuable intermediates in chemical synthesis, particularly in cross-coupling reactions where different chemical entities are combined to form new compounds. For instance, a process called deacylative cross-coupling rem.....»»
Brazil fishermen turn to mobile app to combat pollution scourge
Brazilian activist and fisherman Alexandre Anderson uses one hand to steer his boat, and the other to film an oil stain spreading over Rio de Janeiro's Guanabara Bay......»»
New computational methodology to predict the complex formation of interesting nanostructures
Researchers from the group of Prof. Carles Bo at the Institute of Chemical Research of Catalonia (ICIQ-CERCA) have described a computational methodology that simulates complex processes involving different chemical species and diverse conditions. The.....»»
Scientists propose gliding arc discharge plasma seawater sterilization technology for mariculture
