Study finds concerning variations in care between physicians of the same specialty and in the same city, delivering care in the same clinical scenarios

A new study published in JAMA Health Forum found significant variations in care delivery among physicians with the same specialty and city, despite delivering care in the same clinical scenarios. The researchers analyzed medical insurance records from 2016 to 2019 and found that top-performing physicians were five to 10 times more like...

People are fast and accurate when making high-value decisions

A new study reveals that people are more accurate and faster when making high-value decisions than previously thought. Researchers found that participants could distinguish between high-value items quickly and accurately, even with the added complexity of knowing what type of decision they were about to make.

New study finds staff assumptions about race play a role in the variability of care of nursing homes residents with advanced dementia

A new study found that staff assumptions about minoritized groups contribute to variability in nursing home care for residents with advanced dementia. Remedies include addressing staff biases, increasing funding, and standardizing advance-care planning.

New study examines end-of-life decision making in American prisons

A new study reveals significant variability in state- and nationwide policies on end-of-life decision making in US prisons. The researchers found that many policies restrict access to advance care planning documents, limit the roles of surrogate decision-makers, and fail to ensure compliance with community standards. The study emphasiz...

Naturally healthy: How much do adolescents know about food?

A study found that adolescents' ratings of food products were influenced by naturalness, with simpler judgments on taste components. Experts also applied the same rule, but with more consistent knowledge about food ingredients. The results suggest that nutrition education for adolescents should target their knowledge about food ingredi...

Viruses and game theory

Phages weigh all options and make an informed decision whether to exit the dormant state and attack their bacterial host. The study found that some phage families have developed a complex decision-making strategy, receiving information from neighboring bacteria and controlling communication via arbitrium.

More women on company boards will lead to lower risk-taking and better outcomes

Research by Åbo Akademi University found that companies with more women on their boards tend to make fewer high-risk corporate acquisitions and are more willing to write down goodwill for unsuccessful deals. This suggests that female representation can lead to a more conservative approach to risk-taking and improved financial governance.

Whether people inform themselves or remain ignorant is due to three factors

A new study by UCL researchers found that people's motivation to seek information falls into three categories: expected utility, emotional impact, and frequency of thought. Those who prioritize these factors tend to seek information more, with better mental health reported by those seeking info on frequently thought-about topics.

Researchers investigate link between bilingualism and false memories

A study published in Frontiers in Psychology found that false information in both native and second languages equally contribute to the formation of false memories. The researchers used an online experiment with participants speaking Russian and English to assess the influence of misinformation and source misattribution on memory recall.

Reboot and recall: new brain hub for memory restoration identified

Researchers have found that stimulating the anterior thalamus can increase memory-related brain activity and restore memory function in rats with MTT lesions. The study suggests that therapies targeting this region could help recover memory in patients with brain injury, challenging previous notions of memory recovery.

Computational techniques in ICU: Neural synchrony predicts outcome after coma

Researchers used sound processing to examine neural synchrony in comatose patients. They found that higher neural synchrony was predictive of a favorable outcome, with indistinguishable levels from healthy controls. The study also revealed surprising neural complexity, with reduced complexity in survivors compared to non-survivors.
