Scientists in all fields use a dynamic, open-ended process to investigate questions, known as the scientific method. This is a logical, problem-solving approach to discovering answers that are supported by evidence.

The scientific method is essential because it provides an objective, standardized approach to conducting experiments. Using the scientific method limits the influence of biases and preconceived notions and improves the quality of results.

According to a new analysis, pumas maintain relationships with nearly 500 living species and play an integral role in keeping ecosystems healthy and resilient throughout the Western hemisphere. The study, a collaboration between the conservation organizations Defenders of Wildlife and Panthera, not only demonstrates how pumas link numerous animals and plants but also how the human communities tied to these ecosystems benefit from the big cats.

A bright spot during this COVID-19 pandemic has been the rapid development of effective vaccines that work by harnessing the power of messenger RNA, or mRNA. mRNA vaccines might seem like a relatively new idea, but researchers have been working on the technology behind them for decades. Now, the success of Moderna and Pfizer’s coronavirus vaccines are highlighting the immense potential for mRNA therapies—not just for infectious diseases, but also to treat cancer and genetic disorders.

Decades of research have emphasized the importance of matriarchs in leading elephant herds. A herd, made up of related female elephants and their offspring, depends on the matriarch for guidance and leadership as they travel to find food and water, avoid danger, and bring up babies.

But much less research has investigated the relationships and connections that occur between unrelated male elephants in so-called “bull areas.” According to a new study, the presence of older male elephants within a bull area decreases the likelihood of aggression by other males. The finding could have implications for elephant conservation efforts and human-elephant conflicts.

Suicide is more than just a mental health problem, it’s a social justice and public health issue, according to Meredith Chapman, MD, the medical director of the Center for Suicide Prevention and Research at Nationwide Children’s Hospital.

At a presentation at the recent annual meeting of the American Academy of Child and Adolescent Psychiatry, Dr. Chapman described the implementation and expansion of Zero Suicide at Nationwide Children’s. Zero Suicide is a comprehensive, system-wide approach for health care organizations — including a specific set of tools and strategies — to suicide prevention and intervention.
