A study on natural killer cells in wild mice found that these mice have higher numbers of NK cells compared to lab mice, suggesting a closer representation of human immune systems. The findings support the hypothesis that environmental factors are needed to fully represent the immune system.
A review article finds that men who are prone to anger and have hostile attitudes toward women are more likely to commit sexual aggression when intoxicated. The study suggests that alcohol primarily influences the circumstances under which some men commit sexual assault, rather than who becomes sexually aggressive.

Researchers found insufficient evidence to support the effectiveness of financial incentives in improving primary care services. Despite hundreds of schemes worldwide, there is a risk that these incentives may not produce any effect or have negative outcomes.
Early results suggest that virtual reality (VR) human-computer interfaces can improve arm function and daily activities in adult stroke patients compared to traditional therapy. VR training has been found to have positive effects on these outcomes, but more data is needed to assess the long-lasting benefits of this approach.
A Cochrane Review analyzed 35 Cochrane Reviews of randomized trials to evaluate the effectiveness of 46 different drug/dose combinations against acute pain. The review found that no single drug provides high levels of pain relief for all patients, but some options have a solid evidence base
A Cochrane Systematic Review found that micronutrient powders can reduce anaemia and iron deficiency in infants aged six to 23 months, particularly in Asia, Africa, and the Caribbean. The intervention resulted in a 31% reduction in anaemia risk and a 51% reduction in iron deficiency risk.
A UK study reveals that long-term complications after bariatric surgery should be thoroughly assessed and investigated. A Finnish study finds that bariatric surgery is a more cost-effective way to treat morbid obesity than non-operative care, with reduced healthcare costs and improved quality of life.
A group of researchers argue that ranking drugs by harm is conceptually flawed, as it combines individual harms and societal impacts. They propose more refined tools for policymakers to assess the likely changes in different types of harm associated with each change in drug policy.
A 14-year study found a significant increase in ischemic stroke hospitalizations among adolescents and young adults, with nearly one-third of patients aged 15-34 years also diagnosed with hypertension. The study highlights the need for public health initiatives to reduce risk factors for stroke among this age group.
Researchers found significant soil carbon sequestration under Miscanthus on former tilled land and grasslands after two years of planting. This study suggests that Miscanthus can help limit the release of greenhouse gases without adding to the carbon debt.

The research suggests that its inability to kill large prey may have hastened its extinction, highlighting the vulnerability of large predators with specialized diets.
A recent study found a clear tendency toward favoring items located in the middle of a row, regardless of direction. This 'center-stage effect' may influence choice in various settings, including shopping and surveys.
The São Paulo state government has implemented a bill setting clear requirements for ecological restoration projects, aiming to increase their success rates. However, critics argue that such detailed regulations may not be sufficient to achieve effective ecosystem restoration due to the complexity of the issue.
Patients with rheumatoid arthritis who have higher self-efficacy for physical activity are more likely to achieve their goals. Achieving these goals is associated with reduced arthritis pain and increased health-related quality of life.
Researchers claim most crowd estimations are unreliable due to political bias and have devised new methods for estimating static and mobile crowds with reduced margin of error. The 'area x density' method for static crowds and the 'two-inspection-point' method for mobile crowds can provide more accurate estimates
