This trend is increasing, with potential negative impacts on the quality of scientific work and life-work balance.
A study by Davide Zoccolan and colleagues found that the anterior inferotemporal cortex (IT) categorizes objects based on visual similarity, except for four-legged animals which are represented by semantic meaning. The IT retains a 'raw' lower-level coding of object properties like color and size.
Research suggests that believing in precognition can provide a psychological boost to perceived control, particularly when individuals feel a loss of control. People who experienced loss of control reported increased belief in precognition and subsequently felt more in control.
Researchers found that entrepreneurs exhibit higher levels of rule-breaking behavior during adolescence, such as cheating and truancy. However, this behavior tends to dissipate by adulthood, with most entrepreneurs showing no significant difference in anti-social tendencies compared to non-entrepreneurs.

Access to clean water and soap was associated with reduced microbiological and parasitic infestations, positively impacting child development.
A new study shows that citizen scientists can analyze satellite data and identify human impact as accurately as experts. However, experts were better at identifying specific land cover types. Interactive training and feedback may help non-experts improve their classification rates.
A study found that female deaths are underreported to coroners in England and Wales, with women being half as likely to proceed to an inquest. Men, on the other hand, were overrepresented in occupational diseases and suicide verdicts, while women were more likely to receive natural causes verdicts.
A new study by Jonah Berger and Raghuram Iyengar found that written conversations on Facebook lead to discussions of more interesting products and brands compared to oral conversations. This is because written communication allows consumers time to think before responding, enabling them to select more engaging topics.
A study of over 240,000 participants found that women with a history of kidney stones had an increased risk of coronary heart disease, while no association was seen in men. The researchers suggest further research is needed to determine the underlying cause of this sex-specific association.

A study of nearly 35,000 surgical discharges found that occurrence of postsurgical complications was associated with higher per-encounter hospital contribution margin for Medicare and private insurance patients, but lower one for Medicaid and self-pay patients. This suggests that hospitals may need to adjust their financial strategies ...
A CU-Boulder study found that people reported higher levels of happiness as they reported higher sexual frequency, but also believed their peers were having less sex than them. This 'relative aspect' of sex frequency increases happiness, suggesting social comparisons play a role in the relationship between sex and happiness.

The study highlights the problem of poor service to African-American customers and suggests a solution by promoting tipping norms for specific levels of service quality.
A new study found that 3-year-olds endorse equal sharing norms, but fail to follow them until they reach 7-8 years old. Researchers gave stickers valued by children of all ages and asked about sharing, finding consistent endorsement across ages. However, actual behavior showed a gap between endorsed and followed norms.
A recent survey by NORC at the University of Chicago found that getting ahead is seen as a personal responsibility, with employers investing in training but facing confidence issues. Lower-wage workers are less satisfied and perceive fewer advancement opportunities, with pessimism being acute among white and younger workers.
A study analyzed mood words in 20th century books and found a decrease in emotional words overall, but an increase in fear since the 1970s. Books written in American English are significantly more 'emotional' than their British counterparts.
A study found that adults who experience a stroke before age 50 have a significantly higher risk of death over the next 20 years compared to the general population. The researchers also noted that patients who survive their first 30 days after ischemic stroke are at an increased risk of mortality throughout subsequent decades.
