Social media has opened up a new digital world for psychology research. Researchers are developing new methods of language analysis, and how social media can be leveraged to study personality, mental and physical health, and cross-cultural differences.
Researchers have delved into the effects of experiential purchases, potential negative impacts on abundance, the psychology of lending to friends, and how the wealthy think differently about well-being.
About 10 percent of patients with chronic lymphocytic leukemia discontinued therapy with the Bruton tyrosine kinase inhibitor drug ibrutinib because of disease progression during clinical trials, according to a new study.
Scientists have captured the first detailed microscopy images of ultra-small bacteria that are believed to be about as small as life can get. The existence of ultra-small bacteria has been debated for two decades, but there hasn’t been a comprehensive electron microscopy and DNA-based description of the microbes until now. The cells have an average volume of 0.009 cubic microns (one micron is one millionth of a meter). About 150 of these bacteria could fit inside an Escherichia coli cell and more than 150,000 cells could fit onto the tip of a human hair.
Significant differences were found in hospital re-admissions, medication usage, and both medical and surgical complications of children with Crohn’s disease related to race. In the study, black children had a 1.5 times higher frequency of hospital re-admissions because of Crohn’s disease compared to white children.
Known for their beautiful singing duets, plain wrens of Costa Rica perform precise phrase-by-phrase modifications to the duration between two consecutive phrases, achieving careful coordination as their songs unfold. A new study shows that these songbirds achieve precise coordination by adjusting the period between two consecutive phrases (inter-phrase intervals), depending on whether their song is answered, the phrase type used in the duet and the position of the inter-phrase interval within the duet.
A new type of methane-based, oxygen-free life form that can metabolize and reproduce similar to life on Earth has been modeled. It is theorized to have a cell membrane, composed of small organic nitrogen compounds and capable of functioning in liquid methane temperatures of 292 degrees below zero.
The majority of hospitals participating in the American College of Surgeons National Surgical Quality Improvement Project improve surgical outcomes over time, and improvement continues with each year that hospitals participate in the program, according to a new study.
In a series of three studies, researchers tested whether there is a link between personality and an aspect of physical ecology: flat terrain versus mountainous terrain. The study found that only one of the Big Five personality traits predicted terrain preference — extraversion.
