How molecular entanglements determine the structure of polymers
The structure of semicrystalline polymers largely depends on how strongly their molecular chains are entangled. This has been shown in a new study by researchers from Martin Luther University Halle-Wittenberg (MLU), which was published in the journal.....»»
Machine learning uses X-ray diffraction data from polymers to predict the behavior of new materials
Polymers such as polypropylene are fundamental materials in the modern world, found in everything from computers to cars. Because of their ubiquity, it's vital that materials scientists know exactly how each newly developed polymer will perform under.....»»
Socioeconomics found to shape children"s connection to nature more than where they live
The income and education levels of a child's environment determine their relationship to nature, not whether they live in a city or the countryside. This is the finding of a new study published in People and Nature and conducted by researchers at Lun.....»»
New "chiral vortex" of light allows chemists to "see" molecules through the mirror
An entirely new structure of light is helping to measure chirality in molecules more accurately and robustly than ever before, in a major potential step for the pharmaceutical industry......»»
Researchers synthesize molecular aggregates for solar energy applications
No molecule stands alone—they need others, at least when it comes to being able to display useful photophysical, electronic, and chemical properties. When individual molecules combine into an aggregate, or a complex of two or more molecules, they b.....»»
Stranded student helps design synthetic polymers to combat fungal infections
Every year, more than 2 million people are affected by invasive fungal infections, which are often caused by Candida species and are associated with high mortality rates. The development of new therapies is progressing very slowly. Demand is increasi.....»»
Vulnerability prioritization is only the beginning
To date, most technology solutions focused on vulnerability management have focused on the prioritization of risks. That usually took the shape of some risk-ranking structure displayed in a table with links out to the CVEs and other advisory or threa.....»»
A small molecular glue that increases P53 level and suppresses tumor growth in vivo
Molecular glues are typically small chemical molecules that act on the interface between the target protein and the degradation machinery to trigger ternary complex formation. Identification of molecular glues is challenging, and there has been a lac.....»»
Physicists observe key minuscule molecular interactions in ultra-fast atomic processes
An international team of scientists is the first to report incredibly small time delays in a molecule's electron activity when the particles are exposed to X-rays......»»
App Store VP departing Apple amid broader restructuring
Apple’s App Store vice president is leaving the company in October, according to a new report from Bloomberg. The structure of the App Store team is also being split into two teams, a change implemented by Phil Schiller in response to the ever-.....»»
Survival tactics: AI-driven insights into chromatin changes for winter dormancy in axillary buds
Evolution has enabled plants to survive under adverse conditions. The winter bud of a plant is a crucial structure that establishes adaptability. Depending on environmental and intrinsic conditions, buds can transition between growth and dormancy. Th.....»»
Bacteria make thermally stable plastics similar to polystyrene and PET for the first time
Bioengineers around the world have been working to create plastic-producing microbes that could replace the petroleum-based plastics industry. Now, researchers from Korea have overcome a major hurdle: getting bacteria to produce polymers that contain.....»»
Twisted molecular wires exhibit high single-molecule conductance
From the high-voltage wires that carry electricity over long distances, to the tungsten filaments in our incandescent lights, we may have become accustomed to thinking that electrical conductors are always made of metal. But for decades, scientists h.....»»
Newly discovered, free-living eukaryote is the first known to have lost its mitochondria
An international team of geneticists and molecular biologists has discovered the first-known, free-living eukaryote to have lost its mitochondria. In their study, published in Nature Communications, the group found the eukaryote while investigating t.....»»
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.....»»
Civilization VII hands-on: This strategy sequel rethinks the long game
Classic turn-based gameplay meets a radical rethink of the overall structure. Enlarge / Firaxis has upped the ante on presentation for the cities. It's still a bit abstract and removed, but they have more vibrancy, detail, and mo.....»»
Pore structure characteristics found to influence carbon mineralization under conservation tillage
Soil aggregates are the basic units of soil structure and serve as a reservoir for soil carbon, playing a crucial role in the carbon cycle of ecosystems. The pore characteristics of soil aggregates influence the mineralization of soil organic carbon......»»
Neutrons illuminate environmental and biological mysteries
Neutron techniques have long been valued in various scientific fields for their ability to penetrate materials without altering their structure. However, their use in environmental and biological sciences has been limited. Complex systems like soil-w.....»»
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 supramolecular polymer shows spontaneous unfolding and aggregation
In polymers, the competition between the folding and aggregation of chains, both at an individual level and between chains, can determine the mechanical, thermal, and conductive properties of such materials. Understanding the interplay of folding and.....»»
Sea anemone study identifies potentially regenerative stem cells linked to conserved genes
