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.....»»
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......»»
Research team releases a 76 m-per-pixel global color image dataset and map of Mars
Remote-sensing images of Mars contain rich information about its surface morphology, topography, and geological structure. These data are fundamental for scientific research and exploration missions of Mars. Prior to China's first Mars exploration mi.....»»
Chromatin structure found to play a key role in canine social behavior evolution
A study on dogs found that chromatin's spatial structure has a significant role in the evolution of social behavior. Chromatin, the compact form of DNA, not only packages genetic material but also plays a crucial role in gene regulation......»»
House call: A new study rethinks early Christian landmark
Since its discovery by modern researchers a century ago, an ancient structure known as the "Christian building" has become widely considered the cornerstone of early Christian architecture. Constructed around 232 C.E. in the ancient city of Dura-Euro.....»»
Starvation and adhesion drive formation of keratinocyte patterns in skin, research reveals
Fingerprints are one of the best-recognized examples of pattern formation by epithelial cells. The primary cells in the epithelium are the keratinocytes, and they are known to form patterns at the microscopic and macroscopic levels. While factors aff.....»»
Comparing Apple’s latest App Store changes in the EU to Google’s Play Store guidelines
Last week, Apple announced changes to its compliance strategy with the Digital Markets Act in the European Union. These changes apply to apps that link to a web page and include a new fee structure centered around the Initial Acquisition Fee and the.....»»
Studying the skin of the great white shark could help reduce drag in aircraft
High-ridged dentricles reduce drag at low speeds; alternating ridges do so at high speeds. Enlarge / Great white sharks can reduce drag at different swimming speeds thanks to high and low ridged dentricles in its skin. (credit: T.....»»
Developing a simple, cost-effective method to identify the targets of a crucial protein-modifying enzyme
Human proteins undergo a variety of chemical modifications following their synthesis. These modifications regulate their structure, function, and stability. Researchers from the Bhogaraju Group at EMBL Grenoble have developed a new method to study a.....»»
Align or die: Revealing unknown mechanism essential for bacterial cell division
A previously unknown mechanism of active matter self-organization essential for bacterial cell division follows the motto "dying to align": Misaligned filaments "die" spontaneously to form a ring structure at the center of the dividing cell. The stud.....»»
The Physics of Cold Water May Have Jump-Started Complex Life
When seawater gets cold, it gets viscous. This fact could explain how single-celled ocean creatures became multicellular when the planet was frozen during “Snowball Earth,” according to experiments......»»
How do butterflies stick to branches during metamorphosis?
Most of us learned about butterfly metamorphosis as a kid—a wriggly caterpillar molts its skin to form a tough chrysalis and emerges as a beautiful butterfly. But how exactly do chrysalises stay anchored as the butterfly brews within?.....»»
PhAI—an AI system that figures out the phase of x-rays that crystals have diffracted
A trio of chemists at the University of Copenhagen has developed an AI application that can be used to figure out the phase of x-rays that crystals have diffracted as part of efforts to predict the structure of small molecules......»»
Increasing solid-state electrolyte conductivity and stability using helical structure
Solid-state electrolytes have been explored for decades for use in energy storage systems and in the pursuit of solid-state batteries. These materials are safer alternatives to the traditional liquid electrolyte—a solution that allows ions to move.....»»
Apple announces new fee structure for apps in the EU that link out to the web for purchases
Following the EU ruling in June that said Apple’s App Store anti-steering policies are officially in breach of the Digital Markets Act, Apple is announcing changes. Specifically, these changes address the rules around app developers linking out to.....»»
