Save Your Soybeans and Corn, Iowa’s ‘Goldilocks’ Period Won’t Last
American Institute of Physics (AIP)

Over the past few decades, Iowa’s agriculture has experienced a period of consistently high yields. The perfect distribution and timing of humidity, rainfall and heat have led to bumper crops of corn and soybeans. This “Goldilocks” period is partly due to global warming, but experts believe farmers shouldn’t expect it to last. In Physics Today, scientists Eugene Takle and William Gutowski describe the challenges farmers could expect to see to maintaining high yields if global warming continues along predicted trends.

New Investments and Research Indicate Multi-Trillion Dollar Market for Climate Restoration Through Carbon-Capture
Thunderbird School of Global Management

Climate restoration is the global movement to remove the trillion tons of excess CO2 from the atmosphere to restore our air to preindustrial levels of carbon dioxide and to preserve the Arctic ice. Given the climate emergency, climate restoration is a critical third pillar of climate action, complementing ongoing mitigation and adaptation efforts. New technologies and natural solutions for reducing CO2 levels in the next 30 years already exist and the costs for global-scale implementation are projected to be less than 1-3% of the global annual GDP.

Transformative 'Green' Accelerator Achieves World's First 8-pass Full Energy Recovery
Brookhaven National Laboratory

Scientists from Cornell University and Brookhaven National Laboratory (BNL) have successfully demonstrated the world's first capture and reuse of energy in a multi-turn particle accelerator, where electrons are accelerated and decelerated in multiple stages and transported at different energies through a single beamline.

Newswise: How to Make it Easier to Turn Plant Waste into Biofuels

How to Make it Easier to Turn Plant Waste into Biofuels
Rutgers University-New Brunswick

Researchers have developed a new process that could make it much cheaper to produce biofuels such as ethanol from plant waste and reduce reliance on fossil fuels. Their approach, featuring an ammonia-salt based solvent that rapidly turns plant fibers into sugars needed to make ethanol, works well at close to room temperature, unlike conventional processes, according to a Rutgers-led study in the journal Green Chemistry.

McMaster chemists find new way to break down old tires into material for new ones
McMaster University

A team of chemists at McMaster University has discovered an innovative way to break down and dissolve the rubber used in automobile tires, a process which could lead to new recycling methods that have so far proven to be expensive, difficult and largely inefficient.

Newswise: Supporting Structures of Wind Turbines Contribute to Wind Farm Blockage Effect

Supporting Structures of Wind Turbines Contribute to Wind Farm Blockage Effect
American Institute of Physics (AIP)

Much about the aerodynamic effects of larger wind farms remains poorly understood. New work in this week’s Journal of Renewable and Sustainably Energy looks to provide more insight in how the structures necessary for wind farms affect air flow. Using a two-scale coupled momentum balance method, researchers theoretically and computationally reconstructed conditions that large wind farms might face in the future, including the dampening effect that comes with spacing turbines close to one another.

New Function for Plant Enzyme Could Lead to Green Chemistry
Brookhaven National Laboratory

Scientists at Brookhaven National Laboratory have discovered a new function in a plant enzyme that could inspire the design of new chemical catalysts. The enzyme catalyzes, or initiates, one of the cornerstone chemical reactions needed to synthesize a wide array of organic molecules, including those found in lubricants, cosmetics, and those used as raw materials for making plastics.

Bending an Organic Semiconductor Can Boost Electrical Flow
Rutgers University-New Brunswick

Slightly bending semiconductors made of organic materials can roughly double the speed of electricity flowing through them and could benefit next-generation electronics such as sensors and solar cells, according to Rutgers-led research. The study is published in the journal Advanced Science.
