Diet change -- A solution to reduce water use?

Researchers at Aalto University found that shifting to vegetarian diets can reduce green water use by up to 21% and blue water use by up to 14%. This could secure food supply for an additional 1.8 billion people without increasing water resources.

Anorexia fueled by pride about weight loss

A Rutgers study found that positive emotions, even those viewed through a distorted lens, may play a role in fueling eating disorders like anorexia nervosa. Women with the illness often feel emotionally positive about their weight loss progress, which can lead to a vicious cycle of continued weight loss and disordered behaviors.

Earlier intervention for common form of heart attack linked to improved survival

A UCLA-led analysis found that changes in treatment over the past decade have associated with higher survival rates for all patient groups, regardless of age or risk factors. The study tracked 6.5 million patients treated for heart attacks between 2002 and 2011 and found improved outcomes with earlier cardiac catheterization

Epidemic outbreaks caused by environment, not evolution

A team of scientists has found that genetic changes in a bacterial pathogen may be caused by chance environmental events rather than genetic mutations. The study, published in PNAS, analyzed 149 genomes of Salmonella enterica serovar Paratyphi A and found that the pathogen had not changed dramatically over its 450-year history.

Community pharmacist intervention boosts drug adherence, reduces health-care costs

A study led by the University of Pittsburgh School of Pharmacy found that community pharmacist interventions can significantly boost drug adherence rates. The project showed a 3-4% increase in medication adherence across five common medication classes, resulting in substantial cost savings for healthcare systems. By leveraging pharmaci...

The evolution of migration

A new study published in PNAS suggests that migratory birds evolved from species that lived year-round in North America. Researchers created a model to analyze the evolutionary changes of migratory bird species and found that most species originated from temperate regions before migrating to tropical areas.
