It's not about the money for long-term care nurses

Researchers found that job satisfaction and emotional well-being are better predictors of turnover in long-term care facilities. Certified nursing assistants were more likely to switch jobs due to lower emotional distress and greater job satisfaction after switching, even if it meant taking a pay cut.

A good story can trump a bad credit score in peer-to-peer lending

Research from Rice University and the University of Delaware found that unverifiable information like personal stories enhances lending decisions. Borrowers who explain their circumstances but deny details have poor loan performance. Using a 'trustworthy' identity can lower costs by almost 30% and save $375 in interest charges.

More than 20 percent of atheist scientists are spiritual

A new study from Rice University found that 72 scientists, many of whom identify as atheist, possess a spirituality consistent with science. These 'spiritual atheist' scientists believe in a core sense of truth generated by their work as scientists, and see both science and spirituality as meaning-making without faith.

Unique AED pads give hearts a second chance

Rice University bioengineering students collaborate with the Texas Heart Institute to create unique AED pads that allow rescuers to try again without losing valuable time. The pads have been tested with 100% success rate and are being patented, with hopes of being picked up by an AED manufacturer for FDA approval.

Rice-born detector finds heaviest antimatter

Physicists at Rice University have detected the heaviest antimatter particle ever observed, antihelium-4, using a time-of-flight detector designed at the institution. The discovery provides new insights into the conditions of the early universe and the existence of antimatter galaxies.

New study proves the brain has 3 layers of working memory

Researchers at Rice University and Georgia Tech found evidence for three distinct layers of working memory, including a core focusing on one active item and surrounding areas holding multiple items. Predictability can improve multitasking by automizing certain tasks, allowing individuals to effectively switch between tasks.

Children in public housing play outdoors more

Researchers discovered that young children living in public housing spend more time playing outdoors than their peers, with a significant link to lower body mass indexes (BMIs). Mothers' perceptions of neighborhood environments also played a key role in predicting children's outdoor playtime and TV watching habits.

Study shows that defensive military alliances enhance peace

A new study by Rice University researchers found that countries with defensive military alliances are less likely to be attacked, and these alliances do not increase the likelihood of aggression. The study analyzed defense agreements from 1816 to 2001 and suggests that such alliances can make war and militarized conflicts shorter.

Researchers get a grip on nervous system's receptors

Scientists used single molecule fluorescence resonance energy transfer (FRET) techniques combined with wavelet transforms to study the AMPA receptor's behavior. They identified four distinct conformations of the receptor and found that its 'cleft' is constantly opening and closing, exploring space for neurotransmitters.
