Published Organs on demand? Scientists print voxel building blocks



Scientists are bioprinting 3D structures with a material that is a close match for human tissue, paving the way for true biomanufacturing.
Published Understanding how a red seaweed reduces methane emissions from cows



New research has implications for addressing a leading contributor to climate warming, methane.
Published Genome study informs restoration of American chestnut tree



Researchers use genomes to help restore the American chestnut population and adjust species breeding to the changing climate.
Published Researchers clarify how soft materials fail under stress



Understanding how soft materials fail under stress is critical for solving engineering challenges as disparate as pharmaceutical technology and landslide prevention. A new study linking a spectrum of soft material behaviors -- previously thought to be unrelated -- led researchers to identify a new parameter they call the brittility factor, which allows them to simplify soft material failure behavior. This will ultimately help engineers design better materials that meet future challenges.
Published Waste Styrofoam can now be converted into polymers for electronics



A new study describes a chemical reaction that can convert Styrofoam into a high-value conducting polymer known as PEDOT:PSS. Researchers also noted that the upgraded plastic waste can be successfully incorporated into functional electronic devices, including silicon-based hybrid solar cells and organic electrochemical transistors.
Published Shining light on amyloid architecture



Researchers use microscopy to chart amyloid beta's underlying structure and yield insight into neurodegenerative disease.
Published Chemists design novel method for generating sustainable fuel



Chemists have been working to synthesize high-value materials from waste molecules for years.
Published The rhythm led by plants is crucial for symbiosis with nutrient-providing bacteria



Recent research on Lotus japonicus, a model leguminous plant, has unveiled that the interaction between legume roots and rhizobia is characterized by periodic gene expression with a six-hour rhythm. This rhythmic gene expression influences the regions of the root susceptible to rhizobial infection and the distribution of nodules. It was also discovered that the plant hormone cytokinin is crucial for maintaining this gene expression rhythm.
Published Converting wastewater to fertilizer with fungal treatment



Creating fertilizers from organic waste can help reduce the consumption of fossil fuels and promote sustainable production. One way of doing this is through hydrothermal liquefaction (HTL), which converts biomass into biocrude oil through a high-temperature, high-pressure process. Two studies explore the use of a fungal treatment to convert the leftover wastewater into fertilizer for agricultural crops.
Published How pollution may remain in water after oil spill cleanups



The way oil drops break up at the water's surface means some oil may not get cleaned up after a spill.
Published Solar farms with stormwater controls mitigate runoff, erosion, study finds



As the number of major utility-scale ground solar panel installations grows, concerns about their impacts on natural hydrologic processes also have grown. However, a new study by Penn State researchers suggests that excess runoff or increased erosion can be easily mitigated -- if these 'solar farms' are properly built.
Published Hundreds of new genome sequences fill gaps in the fruit fly tree of life



A multitude of new genomic sequence data fills major gaps in the fruit fly tree of life, researchers report.
Published Small animals acquire genes from bacteria that can produce antibiotics



A group of small, freshwater animals (bdelloid rotifers) protect themselves from infections using antibiotic recipes 'stolen' from bacteria, according to new research. This raises the potential that rotifers are producing novel antimicrobials that may be less toxic to animals, including humans, than those we develop from bacteria and fungi.
Published Analyzing internal world models of humans, animals and AI



Researchers have developed a new formal description of internal world models, thereby enabling interdisciplinary research. Internal world models help to make predictions about new situations based on previous experience and to help find one's bearings. The new formalized view helps to compare world models of humans, animals and AI and to eliminate deficits.
Published Secrets behind viral precision



New research is shedding light on how viruses ensure their survival by precisely timing the release of new viruses. The discovery offers a new theoretical framework for understanding these dynamic biological phenomena.
Published Although tiny, peatland microorganisms have a big impact on climate



Polyphenols are generally toxic to microorganisms. In peatlands, scientists thought microorganisms avoided this toxicity by degrading polyphenols using an oxygen-dependent enzyme, and thus that low-oxygen conditions inhibit microbes' carbon cycling. However, a new study found that Arctic peatland microorganisms used alternative enzymes, with and without oxygen, to break down polyphenols. This suggests carbon stored in these ecosystems is more at risk than previously thought.
Published Microbes found to destroy certain 'forever chemicals'



An environmental engineering team has discovered that specific bacterial species can cleave the strong fluorine-to-carbon bond certain kinds of 'forever chemical' water pollutants, offering promise for low-cost treatments of contaminated drinking water.
Published New antidote for cobra bites discovered



Cobras kill thousands of people a year worldwide and current antivenom treatment is expensive and does not effectively treat the necrosis of the flesh where the bite occurs. Using CRISPR technology, scientists have discovered a commonly available drug can stop the necrosis, potentially saving thousands of lives a year.
Published Ant insights lead to robot navigation breakthrough



Have you ever wondered how insects are able to go so far beyond their home and still find their way? The answer to this question is not only relevant to biology but also to making the AI for tiny, autonomous robots. Drone-researchers felt inspired by biological findings on how ants visually recognize their environment and combine it with counting their steps in order to get safely back home. They have used these insights to create an insect-inspired autonomous navigation strategy for tiny, lightweight robots. It allows such robots to come back home after long trajectories, while requiring extremely little computation and memory (0.65 kiloByte per 100 m). In the future, tiny autonomous robots could find a wide range of uses, from monitoring stock in warehouses to finding gas leaks in industrial sites.
Published Soft, stretchy 'jelly batteries' inspired by electric eels



Researchers have developed soft, stretchable 'jelly batteries' that could be used for wearable devices or soft robotics, or even implanted in the brain to deliver drugs or treat conditions such as epilepsy.
