New research using climate models provides fascinating insights into how environmental conditions influenced the evolution and migration of early humans.

One study uses deep-sea sediment cores to trace the climatic factors that enabled or hindered hominin settlement in Europe, while another study explores the interbreeding opportunities between Neanderthals and Denisovans due to shifting climates. These findings not only enhance our understanding of human history but also underscore the impact of long-term climatic changes on human habitats and interactions.

A new meta-analysis reveals that combining electrical muscle stimulation with resistance training leads to increased strength and muscle mass.

If building strength and muscle mass is part of your New Year’s resolution, you might consider adding a new element to your workout routine.

Neuromuscular electrical stimulation (NMES), also known as electrical muscle stimulation, uses electrical currents to trigger muscle contractions. According to Sudip Bajpeyi, Ph.D., a professor in the Department of Kinesiology at The University of Texas at El Paso, these stimulation devices are user-friendly and widely available. However, he has often wondered, “Can these stimulators offer any benefits when used during resistance training? What does the research say?”

Common methods of communicating flood risk may create a false sense of security, leading to increased development in areas threatened by flooding.

This phenomenon, called the “safe development paradox,” is described in a new paper from North Carolina State University. Lead author Georgina Sanchez, a research scholar in NC State’s Center for Geospatial Analytics, said this may be an unintended byproduct of how the Federal Emergency Management Agency classifies areas based on their probability of dangerous flooding.

The findings are published in the journal PLOS ONE.

Now mice are getting in on the action.

Researchers have developed a set of VR goggles for lab mice for use in brain studies, according to a report published recently in the journal Nature Methods.

Project Hyperion explores the feasibility of crewed interstellar travel via generation ships, using current and near-future technologies. A generation ship is a hypothetical spacecraft designed for long-duration interstellar travel, where the journey may take centuries to complete. The objective of the competition is to design the habitat of the generation ship, including its architecture and society.
