The study found that participants exposed to scarce resources were more likely to do so compared to those exposed to abundant resources.
Resolving conflicts over end-of-life care is crucial for patients and their loved ones. Mayo Clinic experts recommend choosing objective surrogates to represent patients and involving third parties when necessary.
A study by Ohio State University researchers found that writing down thoughts and then disposing of the paper can reduce their influence on mental judgments. Participants who threw away the paper showed no difference in their attitudes towards positive or negative thoughts, suggesting that physical action influences thought use.
A study of Danish soldiers found that childhood experiences of family violence and emotional problems predicted the onset of PTSD. The researchers suggest that social support and camaraderie during army life minimized mental health benefits for these soldiers, leading to increased symptoms after deployment.
A recent study published in Psychological Science found that using a specific frame to describe income inequality can influence people's views on redistributive tax policies. Participants who were told that the rich make more than the poor showed less opposition to raising taxes on the wealthy, while those in control conditions and tho...

A study published in Psychological Science found that individuals are happier when a self-benefiting option is imposed upon them, as it removes feelings of responsibility for the outcome. This is because having no choice eliminates the conflict between self and others.
A recent study published in Psychological Science found that people tend to prefer the option they chose over the one they rejected, and this preference can last for years. The researchers used a vacation destination rating task to demonstrate this effect, which was only observed when participants made their own choices.

A new study published in The FASEB Journal suggests that being born with a low birth weight may increase the risk of developing cardiovascular disease, kidney disease, and diabetes later in life. Researchers found that older female rats had a reduced ability to become pregnant and carried babies that were smaller or lighter in weight.
A new study found that misconduct accounts for two-thirds of all retracted scientific papers, with fraud or suspected fraud being the leading cause. The number of retractions has increased 10-fold since 1975, attributed to a winner-take-all culture in science that rewards publication and reputation over integrity.
A recent study found that nearly 20 percent of people who underwent low back fusion surgery developed post-traumatic stress disorder symptoms. The strongest factor in determining whether a patient suffered PTSD symptoms was a pre-surgery psychiatric disturbance, but some patients without such diagnoses also experienced symptoms.
A study published in Psychological Science found that individuals with clinical depression struggle to differentiate between various negative emotions, including anger and frustration. In contrast, healthy individuals tend to identify specific emotions more accurately.
Nurses played a crucial role in feeding people and restoring their humanity in times of great crisis, as evident during the liberation of Bergen-Belsen at the end of World War Two. The lack of credit given to these women has led to research encouraging nurses to take ownership of patient nutrition and acknowledge its importance.
A new study found that split-dose preparation significantly improved polyp detection rates and adenoma detection rates, as well as the quality of bowel prep and colonoscopy completion rates. This approach involves dividing the preparation into two doses, taken before and after the procedure, to improve patient compliance and efficacy.

Researchers discovered that a protein called SIRT1 rewrites the histone code in developing fetuses, affecting their likelihood of being overweight or obese. Modifying fat intake during pregnancy to a moderate level can benefit children, regardless of mother's size.
The European Menopause and Andropause Society published a clinical guide on low-dose vaginal estrogens for postmenopausal vaginal atrophy, finding them effective in managing symptoms. The guide recommends annual review due to the chronic nature of vaginal atrophy.
A study by the American Heart Association found that transient ischemic attacks (TIAs) and minor strokes can cause significant disability in up to 15% of patients. Thrombolysis treatment may be necessary for these patients, even if symptoms appear mild, to prevent further damage.
A modeling study published in PLOS ONE found that introducing small payments alongside punishment can create stable, righteous societies in the face of corruption. Once corruption is eradicated, it can be held at bay indefinitely even if power inequalities return.
Researchers found that 7 out of 10 top media-covered ADHD studies were refuted or strongly attenuated by later research. This phenomenon may cause significant distortion in health science communication if generalized to other health topics. The study highlights the potential for misleading early results to dominate public discourse.
The study analyzes stock photography agencies' search and visualization systems to determine essential characteristics. Researchers identify the importance of automated tasks, such as image description inheritance and miniature generation, in these systems.
Researchers used a robot named Nexi to test how people assess trustworthiness in others. They found that sets of non-verbal cues, not just one cue, determine a person's trustworthiness. Participants exposed to untrustworthy cues with Nexi adjusted their financial decisions accordingly.
A new study examines the role of psychological distance and violation severity in humor, suggesting that a balance between the two is necessary for comedy. The findings support the 'Benign Violation Theory,' which proposes that humor emerges when we perceive something wrong while seeing it as okay.
Researchers explore three levels of hindsight bias: memory distortion, inevitability, and foreseeability. Factors fueling the phenomenon include selective recall, need for closure, and overconfidence in judgments. This bias can hinder learning and lead to poor decision-making.
Researchers at the University of Copenhagen have developed a model that links solar insolation to layer formation in Mars's ice caps. The model demonstrates a correlation between ice and dust accumulation and solar insolation, providing a dated climate history for Mars over 1 million years.
The Canadian government's plan to discontinue the Experimental Lakes Area (ELA) has sparked widespread concern among scientists. The ELA, comprising 58 freshwater lakes in Ontario, Canada, has yielded significant insights into water pollution and climate change over nearly 40 years.

The famous Galilean thermometer was actually invented by an early scientific society founded by Galileo
Researchers tracked albatross movements using GPS to discover the 'dynamic soaring' technique, which allows birds to fly with minimal mechanical cost. This method may lead to advancements in robotic aircraft design, enabling them to harness wind energy without engines.
The International Commission on Zoological Nomenclature (ICZN) has passed an amendment allowing purely digital publications to meet its requirements. This change aims to speed the process of publishing biodiversity information, improve access, and reduce the 'taxonomic impediment' hindering cataloguing. The new rules open the door to e...
A study found that people drove more after 9/11, with increases strongly associated with greater driving opportunity. This suggests that fear alone may not be enough to change behavior, and environmental factors play a crucial role in shaping our actions.
Researchers have discovered that Grb10 protein plays a crucial role in increasing muscle mass during development, which could lead to new strategies for treating muscle wasting conditions and metabolic disorders. The study found that blocking Grb10 function while mice were in the womb resulted in increased muscle strength and mass.
A cross-cultural study found that Japanese participants showed higher wisdom scores than Americans in resolving group conflicts, while older age was associated with increased wisdom for Americans but not Japanese. This research highlights the importance of culture on human development and lifespan development.
Researchers at Lund University found that a lower percentage of women than men are invited to write articles in top science journals. This results in women being less visible and having reduced career advancement opportunities. The authors call for increased inclusion of women in invitation-only sections.
