What happens when cosmic giants meet galactic dwarfs?

A study of over 20,000 merging galaxies found that when two galaxies collide, the larger one can stop the smaller one from forming new stars. However, when two galaxies of similar mass collide, they both increase their stellar birth rate.

Surgeries before college athletics may result in more injuries during college play

Research suggests that athletes who underwent lower extremity surgeries before college may be left with functional deficits, increasing their risk of future injuries. The study, which analyzed data from over 1,100 athletes, found that pre-college surgeries were associated with a higher incidence of intracollegiate surgeries.

Ultrasound accelerates skin healing -- especially for diabetics and the elderly

Researchers have discovered that low-intensity ultrasound can stimulate and accelerate wound healing in individuals with chronic wounds, particularly those with diabetes or age-related circulatory issues. This breakthrough has the potential to save the NHS £3.1 billion annually and improve treatment outcomes for over 200,000 patients.

Documentation of hospital patients' malnutrition helps maximize care and reimbursement

A new review published in Nutrition in Clinical Practice found that accurate malnutrition diagnosis and coding can increase hospital payments. The American Society for Parenteral and Enteral Nutrition recommends a valid program to identify, document, intervene, and code malnutrition to enhance financial stability and clinical resources.

Worms hitch rides on slugs when traveling to far flung places

Researchers found that nematode worms commonly inhabit slugs, woodlice, and centipedes, using them as public transport to find new food sources. The worms survive inside slug intestines and are excreted alive, suggesting a potentially harmless but also possibly parasitic association.
