Researchers analyzed meteorological data from nine Upper Midwest states from 1979-2021, tracking trends in extreme heat and cold over every 4-kilometer square of that territory. They found striking regional differences in the extremes. Many parts of the Upper Midwest experienced significant upticks in the number of extreme heat days over the 40 years — an increasing trend — while others saw a rise in extreme cold events. Some communities experienced more of both extremes. Others appeared to be more resistant to changes in extreme heat or cold.

Participants on a self-directed dietary education program who had the greatest success at losing weight across a 25-month period consumed greater amounts of protein and fiber, a study found. Personalization and flexibility also were key in creating plans that dieters could adhere to over time. 

You’ve probably heard that cultivating gratitude can boost your happiness. But in marriage and families, it’s not just about being more grateful for your loved ones — it’s also important to feel appreciated by them.

Elephant conservation is a major priority in southern Africa, but habitat loss and urbanization mean the far-ranging pachyderms are increasingly restricted to protected areas like game reserves. The risk? Contained populations could become genetically isolated over time, making elephants more vulnerable to disease and environmental change. 

Black Americans experience racial discrimination on a regular basis, and it is a cause of chronic and pervasive stress. It is known to contribute to elevated risk for poor mental health outcomes, but most research has focused on individuals.

If you enjoy a bowl of plain yogurt in the morning, adding a spoonful of honey is a delicious way to sweeten your favorite breakfast food.

A bad case of the flu during pregnancy can increase the risk for fetal neurodevelopmental disorders such as schizophrenia and autism spectrum disorder. But it’s not the virus itself doing the damage; it’s the mother’s immune response. 

Researchers analyzed the financial and environmental costs and benefits of four biofuels crops used to produce sustainable aviation fuels in the U.S. They found that each feedstock — corn stover, energy sorghum, miscanthus or switchgrass — performed best in a specific region of the rainfed United States. Their study will help growers and policymakers select the feedstocks most suited to meeting goals like reducing production costs, lowering greenhouse gas emissions and building soil carbon stocks. 

Creating fertilizers from organic waste can help reduce the consumption of fossil fuels and promote sustainable production. One way of doing this is through hydrothermal liquefaction (HTL), which converts biomass into biocrude oil through a high-temperature, high-pressure process.

Raw poultry is one of the main causes of Salmonella poisoning, which affects thousands of people in the U.S. every year.
