Inventing a new, faster way to produce sustainable, self-dyed leather alternatives is a major achievement for synthetic biology and sustainable fashion. Professor Tom Ellis
Synthetic chemical dyeing is one of the most environmentally toxic processes in fashion, and black dyes – especially those used in colouring leather – are particularly harmful. The researchers at Imperial set out to use biology to solve this.
How can older trees help combat climate change? This is what a recent study published in Nature Climate Change hopes to address as an international team of researchers investigated changes in woody biomass in older trees that have been while exposed to free-air CO2 enrichment (FACE) resulting from climate change. This study holds the potential to help researchers, climate scientists, and the public better understand the steps that can be taken to decrease CO2 emissions and combat climate change worldwide.
For the study, the researchers, led by the University of Birmingham’s Institute of Forest Research (BIFoR), conducted a FACE experiment through a combination of canopy laser scanning and tree-ring analysis to examine the 180-year-old Quercus robur L. woodland in central England between 2021and 2022. The goal was ascertaining the effectiveness of older trees compared to younger trees regarding their consumption of CO2, also known as CO2 storage. In the end, the researchers found increased levels of CO2 compared to ambient conditions in 2021 and 2022, respectively, equivalent to 1.7 tons of dry matter per hectare per year.
“Our findings refute the notion that older, mature forests cannot respond to rising levels of atmospheric CO2, but how they respond will likely depend on the supply of nutrients from the soil,” said Dr. Richard Norby from the University of Birmingham, who is lead author of the study. “Evidence from BIFoR FACE of a significant increase in woody biomass production supports the role of mature, long-established, forests as natural climate solutions in the coming decades while society strives to reduce its dependency on carbon.”
Researchers at the University of Maryland genetically modified poplar trees to produce high-performance, structural wood without the use of chemicals or energy-intensive processing. Made from traditional wood, engineered wood is often seen as a renewable replacement for traditional building materials like steel, cement, glass and plastic. It also has the potential to store carbon for a longer time than traditional wood because it can resist deterioration, making it useful in efforts to reduce carbon emissions.
But the hurdle to true sustainability in engineered wood is that it requires processing with volatile chemicals and a significant amount of energy, and produces considerable waste. The researchers edited one gene in live poplar trees, which then grew wood ready for engineering without processing.
The research was published online on August 12, 2024, in the Journal Matter.
Australian scientists have joined an elite club of just eight around the world, making a perovskite solar cell that can hit 30 per cent efficiency.
Led by storied University of Sydney professor Anita Ho-Baillie, the Sydney team’s work was weighed and measured by the US National Renewable Energy Laboratory (NREL).
“It shows that we are capable of producing high performance cells. The next step we will achieve is higher performance, either by double junction or triple junction,” Ho-Baillie says.
This LHP (loop heat pipe) is unprecedented in transporting such a large amount of heat without electricity.
In a groundbreaking development, scientists at Nagoya University in Japan have created the world’s most powerful loop heat pipe (LHP), capable of transporting an astounding 10 kilowatts of heat without using any electricity. This innovation promises to revolutionize energy efficiency across multiple industries, from electric vehicles to data centers.
Understanding Loop Heat Pipes
Before delving into the significance of this breakthrough, let’s explore what loop heat pipes are and how they work. LHPs are passive heat transfer devices that use the principles of phase change and capillary action to move heat from one place to another. They consist of an evaporator, a condenser, and connecting pipes filled with a working fluid.
