Published Despite being properly treated and highly diluted, wastewater still impacts on the river ecosystem



An experiment using water from a large wastewater treatment plant has shown that this water continues to affect river diversity and the trophic web (food web) despite being properly treated and highly diluted before discharge. The study shows that the limits currently in place and the procedures used to treat wastewater may not be sufficient to protect the natural properties of food webs.
Published Copper-based catalysts efficiently turn carbon dioxide into methane


Copper-based catalysts developed by materials scientists help speed up the rate of carbon dioxide-to-methane conversion.
Published By air, rain and land: How microbes return after a wildfire


Ecological disturbances like wildfires disrupt microbial communities. Researchers found that dispersal played a pivotal role in re-establishing surface-level communities.
Published Nanofluidic device generates power with saltwater



There is a largely untapped energy source along the world's coastlines: the difference in salinity between seawater and freshwater. A new nanodevice can harness this difference to generate power.
Published AI increases precision in plant observation



Artificial intelligence (AI) can help plant scientists collect and analyze unprecedented volumes of data, which would not be possible using conventional methods. Researchers have now used big data, machine learning and field observations in the university's experimental garden to show how plants respond to changes in the environment.
Published Conversations with plants: Can we provide plants with advance warning of impending dangers?



Plant scientists have engineered a light-controlled gene expression system (optogenetics system) from a prokaryotic system into a eukaryotic system that is tailored for plants.
Published We could sequester CO2 by 're-greening' arid lands, plant scientists say



Reducing CO2 levels in the atmosphere will take more than cutting emissions -- we will also need to capture and store the excessive volumes of already-emitted carbon. A team of plant scientists argue that arid lands such as deserts could be one answer to the carbon-capture problem.
Published This parasitic plant convinces hosts to grow into its own flesh--it's also an extreme example of genome shrinkage



Balanophora shed one third of its genes as it evolved into a streamlined parasitic plant -- an extreme degree of genome shrinkage even among parasites. Along the way this subtropical plant developed the ability to induce the host plant to grow into the parasite's own flesh -- forming chimeric organs that mix host and parasite tissues.
Published How climate warming could disrupt a deep-rooted relationship


Trees depend on fungi for their well-being. As climate change and global warming cause higher temperatures and amplified drought, little is known about how these important fungi will respond. To investigate this issue, a research team conducted a climate change experiment where they exposed boreal and temperate tree species to warming and drought treatments to better understand how fungi and their tree hosts respond to environmental changes. Their findings revealed that the combined effects of warming and water stress will likely result in major disturbances of ectomycorrhizal networks and may harm forest resilience and function.
Published No shortcuts: New approach may help extract more heat from geothermal reservoirs


Geothermal heat offers a promising source of renewable energy with almost zero emissions, but it remains a relatively expensive option to generate electricity. A new technique may help prevent 'short-circuits' that can cause geothermal power plants to halt production, potentially improving the efficiency of geothermal power, the researchers said.
Published New method for purifying drinking water could be used in disaster zones


Scientists have developed a new desalination method that pumps water through a membrane without using any external pressure.
Published Unzipping mRNA rallies plant cells to fight infection



Living things from plants to humans must constantly adjust the chemical soup of proteins -- the workhorse molecules of life -- inside their cells to adapt to stress or changing conditions. Now, researchers have identified a previously unknown molecular mechanism that helps explain how they do it. A team now reveals hairpin-like structures of mRNA that, by zipping and unzipping, help cells change the mix of proteins they produce when under stress.
Published Researchers reveal the origins of zirconium nitride's superior performance


A group of researchers have unraveled the mysteries behind a recently identified material -- zirconium nitride (ZrN) -- that helps power clean energy reactions. Their proposed framework will help future designs for transition metal nitrides, paving a path for generating cleaner energy.
Published One-atom-thick ribbons could improve batteries, solar cells and sensors


Researchers created nanoribbons made of phosphorus and tiny amounts of arsenic, which they found were able to conduct electricity at temperatures above -140 degrees Celsius, while retaining the highly useful properties of the phosphorus-only ribbons.
Published Material would allow users to 'tune' windows to block targeted wavelengths of light


Researchers have demonstrated a material for next generation dynamic windows, which would allow building occupants to switch their windows between three modes: transparent, or 'normal' windows; windows that block infrared light, helping to keep a building cool; and tinted windows that control glare while maintaining the view.
Published Sustainable energy for aviation: What are our options?


Scientists and industry leaders worldwide are looking for answers on how to make aviation sustainable by 2050 and choosing a viable sustainable fuel is a major sticking point. Aerospace engineers took a full inventory of the options to make a data-driven assessment about how they stack up in comparison. He reviewed over 300 research projects from across different sectors, not just aerospace, to synthesize the ideas and draw conclusions to help direct the dialogue about sustainable aviation toward a permanent solution.
Published Efficient next-generation solar panels on horizon following breakthrough


A scientific breakthrough brings mass production of the next generation of cheaper and lighter perovskite solar cells one step closer.
Published Plant and forest researchers do not 'anthropomorphize' plants



Plants are often attributed with abilities similar to those known in the animal or human world. Trees are said to have feelings and can therefore care for their offspring, like mothers. Researchers analyzed the claims in two popular publications on forests and reached the conclusion that conjecture is equated with fact. They warn against 'anthropomorphizing' plants.
Published Researchers issue urgent call to save the world's largest flower -Rafflesia -- from extinction



A new study finds that most Rafflesia species, which produce the world's largest flowers, face extinction. Lack of protection at local, national, and international levels means that remaining populations are under critical threat.
Published Electrons take flight at the nanoscale


A study showing how electrons flow around sharp bends, such as those found in integrated circuits, has the potential to improve how these circuits, commonly used in electronic and optoelectronic devices, are designed.
