Not so obvious: Consumers don't just assume bundled products are a better value

A new study in Journal of Consumer Research reveals that consumers may not perceive bundled products as a better value. Retailers need to highlight the benefits of package deals to attract customers. By presenting both individual and bundled options, businesses can make consumers aware of the added value and increase sales

Death of a dynamo -- A hard drive from space

Researchers capture asteroid magnetic field moments, revealing extended lifetimes and creating mechanisms similar to the Earth's own magnetic field. Ancient meteorites provide a cosmic archaeological mission, shedding light on the magnetic history of asteroids and their impact on the Earth's core future.

Self-assembled nanotextures create antireflective surface on silicon solar cells

Researchers at Brookhaven National Laboratory developed a method to create an antireflective surface on silicon solar cells using self-assembled nanotextures inspired by the structure of moths' eyes. The resulting surface reduces reflections and improves sunlight conversion, outperforming state-of-the-art coatings by up to 20%.

More realistic physical activity targets needed, say experts

Research suggests that aiming for 150 minutes of moderate-intensity exercise per week may be unrealistic for some adults, particularly older individuals. Increasing daily physical activity by even small amounts can lead to significant health benefits, as shown in studies of moderate to vigorous exercise.

Long-term use of ventricular assist devices induces heart muscle regeneration, study finds

A study by UT Southwestern Medical Center investigators found that patients with heart failure who used left ventricular assist devices (LVADs) for six months or longer showed significant regeneration of heart muscle. Oxidative damage to a cell-regulator mechanism was prevented, leading to an increase in cardiomyocyte proliferation.
