Despite being properly treated and highly diluted, wastewater still impacts on the river ecosystem      (via sciencedaily.com)     Original source 

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.

AI increases precision in plant observation      (via sciencedaily.com)     Original source 

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.

We could sequester CO2 by 're-greening' arid lands, plant scientists say      (via sciencedaily.com)     Original source 

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.

This parasitic plant convinces hosts to grow into its own flesh--it's also an extreme example of genome shrinkage      (via sciencedaily.com)     Original source 

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.

How climate warming could disrupt a deep-rooted relationship      (via sciencedaily.com) 

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.

No shortcuts: New approach may help extract more heat from geothermal reservoirs      (via sciencedaily.com) 

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.

Unzipping mRNA rallies plant cells to fight infection      (via sciencedaily.com)     Original source 

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.

Material would allow users to 'tune' windows to block targeted wavelengths of light      (via sciencedaily.com) 

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.

Plant and forest researchers do not 'anthropomorphize' plants      (via sciencedaily.com)     Original source 

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.
