When something goes wrong during DNA replication, cells call their own version of 911 to pause the process and fix the problem -- a failsafe that is critical to maintaining health and staving off disease. Now, scientists have for the first time revealed how a key piece of this repair...
Microbial communities where cells cooperate have increased drug tolerance
Research has revealed a key mechanism which increases tolerance to drugs amongst microbial communities. The findings could help the development of more effective antifungal treatments.
Effectiveness of antibiotics significantly reduced when multiple bugs present
A study has found that much higher doses of antibiotics are needed to eliminate a bacterial infection of the airways when other microbes are present. It helps explain why respiratory infections often persist in people with lung diseases such as cystic fibrosis despite treatment.
Artificial intelligence paves the way to discovering new rare-earth compounds
Artificial intelligence advances how scientists explore materials. Researchers trained a machine-learning (ML) model to assess the stability of rare-earth compounds. The framework they developed builds on current state-of-the-art methods for experimenting with compounds and understanding chemical instabilities.
Researchers use unique ingredient to strengthen bamboo
Researchers have adapted a technique -- originally designed to embalm human remains -- to strengthen the properties of biocomposites and make them stronger. With the innovation of new materials and green composites, it is easy to overlook materials like bamboo and other natural fibers, explains one of the researchers. These...
Conversion process turns pollution into cash
Engineers have developed a promising electrochemical system to convert emissions from chemical and power plants into useful products while addressing climate change.
Wildfires devastate the land they burn, and they are also warming the planet
The 2021 wildfire season broke records globally, leaving land charred from California to Siberia. The risk of fire is growing, and a recent report warned that wildfires are on track to increase 50% by 2050. These fires destroy homes, plant life, and animals as they burn, but the risk doesn't...
New, possibly arboreal rice rat species discovered in Ecuador
Three expeditions led an international research to the Cordillera de Kutukú, an isolated mountain range in Ecuador, to find just one specimen of the previously unknown species. The find in the Amazonian side of the Andes underlines the valuable biological role of this mountainous region.
The colored skeletons of Çatalhöyük, Turkey, from 9,000 years ago
An international team provides new insights about how the inhabitants of the 'oldest city in the world' in Çatalhöyük (Turkey) buried their dead. Their bones were partially painted, excavated several times and reburied. The findings provide insight into the burial rituals of a fascinating society that lived 9000 years ago.
Visible ocean plastics just the tip of the iceberg
Simulating a half century of movement and degradation of plastic waste in the ocean, a new study estimates that nearly two-thirds of ocean plastics are outside the reach of current monitoring methods. Furthermore, the study suggests that the estimated 25.3 million metric tons of total ocean plastics may represent only...
