Nitric oxide overload jams plant immune signals, researchers find
Nitric oxide overload jams plant immune signals, researchers find Gaby Clark Scientific Editor Robert Egan Associate Editor A new study from the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment (CAFE) helps explain how plants can lose track of their own disease warnings. Plants do not have blood, nerves or immune cells like people do, but they still have ways to protect themselves. When one leaf is attacked by a pathogen, the plant can send warning signals to...
How drought rewires roots, cutting iron uptake across major food crops
How drought rewires roots, cutting iron uptake across major food crops Sadie Harley Scientific Editor Robert Egan Associate Editor New research by scientists at the University of Calgary has found that plants, ranging from canola to rice to tomatoes, actively shut down their own ability to take up iron when they experience drought. It's a finding that could have implications for the nutritional value of agricultural crops. The study, published in the journal Cell, questions whether plants...
Plants could be used to grow medicines in space, study shows
Plants could be used to grow medicines in space, study shows Lisa Lock Scientific Editor Robert Egan Associate Editor Astronauts on long space missions may one day use plants to produce fresh stocks of medicines on demand, thanks to new research by engineers at the University of California San Diego. The team developed a simple method to grow and repeatedly harvest pharmaceuticals from plants under space-like conditions, without destroying the plants or generating large amounts of waste. The...
The World Cup pitches are the result of years of engineering to find just the right grass
The World Cup pitches are the result of years of engineering to find just the right grass Andrew Zinin Lead Editor The World Cup pitches cover so much ground they'll be hard to ignore. The crews that put them there would prefer if fans didn't notice them at all. While it took a herculean effort to engineer the right grass for the different stadiums and to make sure it's in pristine condition for the duration of the tournament, the goal is that it never really attracts attention.
Medicinal plants yield carbon nanoparticles that glow red and flag toxic metals
Medicinal plants yield carbon nanoparticles that glow red and flag toxic metals Stephanie Baum Scientific Editor Robert Egan Associate Editor What do iron, lead and nickel have in common? These heavy metals are an indispensable part of many industries. However, they also share a dark reality: They are serious environmental and public health threats.
From flat moss to forests and flowers: Protein discovery may explain how plants conquered land
From flat moss to forests and flowers: Protein discovery may explain how plants conquered land Sadie Harley Scientific Editor Robert Egan Associate Editor If plants had never learned to grow in multiple directions, our world would look very different. No trees, flowers, or other complex plants—and therefore no animals or humans. New research from the University of Copenhagen now suggests that a specific protein in moss may have been crucial for this key step in plant evolution—a step that...
Beetle mating rituals key to Banksia populations
Beetle mating rituals key to Banksia populations Lisa Lock Scientific Editor Andrew Zinin Lead Editor The nocturnal mating rituals of hairy scarab beetles are helping pollinate one of Perth's most common native trees, in a discovery that highlights the unusual adaptations of Australian plants and the unexpected pollination strategies still to be discovered. A four-year study led by La Trobe University discovered that the candlestick banksia is a rendezvous site for beetles to mate and feed...
Infrastructure for African mines destroying forests at 34 times the rate of the mines themselves
Infrastructure for African mines destroying forests at 34 times the rate of the mines themselves Gaby Clark Scientific Editor Robert Egan Associate Editor Industrial-scale mining in Africa to support global supply chains is leading to unprecedented deforestation across the continent, with 34 hectares of forest removed for every single hectare of active mine site. The scale of mining's deforestation footprint is laid bare in a new University of Sheffield-led study showing that, between 2001...
Arizona, Nevada Agree to Trade for Desalinated Pacific Ocean Water

Lignin to adipic acid in a high-yield chemical and biological redox process
Abstract Viable manufacturing pathways to produce bio-based chemicals from renewable feedstocks, such as lignin derived from plant biomass, are needed to decarbonize the chemicals manufacturing sector. Converting the recalcitrant lignin polymer to valuable bioproducts remains a longstanding challenge in biorefining, with the highest reported single-product yield from lignin currently around 20 wt% (refs. Most existing lignin depolymerization strategies target aryl–ether bond cleavage, which...
