Chemists obtain derivatives of the natural polymer chitosan, which outpace existing antibiotics
RUDN University chemists and colleagues from Belarus obtained derivatives of the natural polymer chitosan, which exceeded existing antibiotics in antibacterial activity. Moreover, the new substances are non-toxic, and the production method is safe. T.....»»
Bacterial pathogen must balance between colonizing airways and developing antibiotic tolerance, study reveals
Imagine trying to settle into a new home while constantly being attacked. That's what the bacterium Pseudomonas aeruginosa faces when it infects the lungs, and it can't both spread and protect itself from antibiotics at the same time......»»
From fireflies to drones: Researchers uncover strategy for synchronization efficiency
Researchers from The University of New Mexico School of Engineering looked to the natural world to explain how synchronized systems can work more efficiently and made a significant discovery. Their results were published in the journal Nature Communi.....»»
Chemists develop a metal-free way to selectively convert symmetrical diols into one of two mirror-image isomers
A team of chemists at the University of Cambridge has developed a metal-free way to convert symmetrical diols selectively into one of two mirror-image isomers. In their paper published in the journal Science, the group took advantage of the ability o.....»»
Natural compound found in flowers blocks activity of an enzyme involved in multiple sclerosis and cancer
Scientists have identified a natural compound that halts the process involved in the progression of certain forms of cancer and demyelinating conditions—those that damage the sheath, known as myelin, that surrounds neurons—such as multiple sclero.....»»
Nanomedicine advances deliver precise antibiotic doses to fight infections and drug resistance
Researchers from the University of Waterloo have developed a new technology that can hold an entire course of antibiotics in one tiny dose and deliver on demand just the right amount of medication that a particular patient needs to fight an infection.....»»
Molecular insights into the dynamic dance of nanoplastics and natural organic matter
Nanoplastics, emerging as persistent environmental pollutants, pose significant threats due to their durability and wide distribution in water bodies. Their interactions with natural organic matter are critical, influencing pollutant retention, micro.....»»
Can we ever trust photos again, in an AI age? Apple and others working the problem
At a time when you can ask AI to modify an existing photo in almost any way you please, or even ask it to generate a completely artificial image, can we ever trust photos again? Apple is working to address the issue in two ways, and many of us are.....»»

Alleged iPhone SE 4 dummy units show iPhone 14 design, apparent ‘Plus’ size option
Some new images of iPhone SE 4 dummy units have been shared by Japanese Apple blog Macotakara today, showcasing a similar form factor to the iPhone 14, as we’d been expecting. The blog also highlights compatibility with existing iPhone 14 cases, an.....»»
X-ray spectroscopy study maps ultrafast charge delocalization in aqueous environments
The movement of electron density is a subject of interest for chemists worldwide, as substances interact through electrons. These processes are ultrafast and traditionally require time-resolved experiments at the attosecond level to study and describ.....»»
Researcher finds special proteins are key when antibiotic resistance spreads
Antibiotic resistance is a growing public health problem globally. The problem is exacerbated by the fact that some bacteria that have become resistant to antibiotics have the ability to spread that resistance to other bacteria via secretion systems......»»

The iPhone 17 Pro and Pro Max might receive a telephoto lens four more times powerful than the existing 12MP camera......»»
New study investigates insecticide contamination in Minnesota"s water
A new study by researchers at the University of Minnesota Twin Cities in collaboration with the Minnesota Department of Natural Resources (DNR) found that specific insecticides, called neonicotinoids, were found at high concentrations in some ground.....»»
Five surprising ways that trees help prevent flooding
Think of flood prevention and you might imagine huge concrete dams, levees or the shiny Thames barrier. But some of the most powerful tools for reducing flood risk are far more natural and widely recognizable: woodlands and green spaces. Trees offer.....»»
Lignin molecular property discovery could help turn trees into affordable, greener industrial chemicals
Trees are the most abundant natural resource living on Earth's land masses, and North Carolina State University scientists and engineers are making headway in finding ways to use them as sustainable, environmentally benign alternatives to producing i.....»»
Forest fires are shifting north and intensifying—here"s what that means for the planet
Fires have long been a natural part of forest ecosystems, but something is changing. Our new study shows that forest fires have become more widespread and severe amid global heating, particularly in the high northern latitudes such as Canada and Sibe.....»»
Tech can help kids connect with nature and go outdoors—here are tips to make it work
Young children's lives are increasingly spent indoors. They have less access to green spaces, their parents are concerned about safety, and there's also the draw of digital entertainment. This shift away from the natural world has been evocatively na.....»»
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.....»»
