The algorithm has already been used by the Alliance for Paired Donation, a kidney exchange program, to identify potential transplants and improve transplant rates.
A new Oregon State University study found that salvage logging and replanting increased fire severity in areas burned by the 2002 Biscuit Fire. Natural regeneration of forests appeared to result in less risk of severe future fires.
A recent study found that nearly all petting zoos have hand hygiene facilities, but compliance is often low. Food and drinks are commonly allowed in petting zoos, posing a risk to infants and children. Implementing simple measures such as signage and running water can increase hand hygiene compliance.
A survey of 415 adults in the US found that 78.1% of patients wanted physicians to shake hands, while 50.4% preferred their first name used during greetings. The study suggests that physicians should use patients' first and last names when introducing themselves and remain sensitive to nonverbal cues.
A study in Injury Prevention reveals California's tougher gun show controls have drastically reduced the sale of firearms linked to crimes. The stricter regulations have also limited the availability of assault-style weapons and banned certain types of rifles and handguns.

A recent study published in PNAS U.S.A. utilized functional MRI to examine the brain activity of awake, mildly sedated zebra finches during song stimulation. The research found that the right side of the birds' brains discriminated sounds better, suggesting a possible link between bird song and human speech disorders like stuttering.
Research suggests that individuals with sleep problems are less likely to cook at home and opt for restaurant-prepared meals, leading to a diet lacking in nutritional value. The study also found that prolonged sleep deprivation can contribute to weight and health issues related to nutrition.
Researchers found that mothers' brains respond more quickly and robustly to ultrasonic calls of mouse pups, enabling them to detect and discriminate between sounds. This improvement in brain function is associated with the ability to recognize behaviorally significant sounds, such as those made by their young.
A study found that men and women with diabetes at age 50 and older have a significantly reduced life expectancy and fewer years without cardiovascular disease. This increase in risk of illness and death is attributed to the global prevalence of Western lifestyle habits, leading to an alarming rise in diabetes cases.

Research shows that premature infants and toddlers are more likely to develop a sleep-related breathing disorder earlier than expected, with higher rates than full-term infants. The study also found that these children tend to be underweight, which is consistent with the poor growth patterns seen in SRBD patients.
Patients who experience a significant drop in blood pressure during bypass surgery may be at risk for early difficulties in thinking, learning, and memory. Those with higher pre-surgery blood pressure levels were more likely to have decreased cognitive scores after the procedure.
