A new study by Los Alamos National Laboratory scientists and colleagues confirms that increasing minimum winter temperatures allow beetles to expand their range but reveals that overcrowding can put the brakes on population growth.

A heat wave sweeps through a city and people swelter, running indoors to find air conditioning. But crops out in a field aren’t so lucky. For them, there is no escape.

Deforestation, greenhouse gas emissions, biodiversity loss, nitrogen pollution – today’s agricultural feed cultivation for cattle, pigs and chicken comes with tremendous impacts for the environment and climate. Cultivating feed in industrial facilities instead of on croplands might help to alleviate the critical implications in the agricultural food supply chain. Protein-rich microbes, produced in large-scale industrial facilities, are likely to increasingly replace traditional crop-based feed. A new study now published in the journal Environmental Science & Technology for the first time estimates the economic and environmental potential of feeding microbial protein to pigs, cattle and chicken on a global scale. The researchers find that by replacing only 2 percent of livestock feed by protein-rich microbes, more than 5 percent of agricultural greenhouse gas emissions, global cropland area and global nitrogen losses could each be decreased.

Reductions in water use first observed in 2010 continue, show ongoing effort towards “efficient use of critical water resources.”

American swamp sparrows may have sung the same songs for more than 1,000 years and passed them on through generations by learning, according to researchers at Queen Mary University of London, Imperial College London and Duke University.
