Why are many dialysis patients readmitted to the hospital soon after discharge?

A study found nearly a quarter of dialysis patients are readmitted to the hospital within 30 days, often for a diagnosis different from their initial hospitalization. Patient characteristics such as female gender, younger age, and certain medical conditions were linked to a high likelihood of readmission.

Multinationals operating in tax havens avoid reporting specifics, finds study

A new study finds that US multinationals operating in tax havens often report earnings by broad categories instead of individual countries, making it harder to track profits and identify potential tax avoidance. Larger companies and those in resource-intensive industries are particularly likely to be vague about their reporting.

Color naming across languages

Researchers analyzed color-naming data from 110 languages and found that warm colors like red, yellow, and orange are generally easier to communicate than cool colors like blue and green. The study suggests that differences in color categorization may reflect cultural differences in color usefulness.

Dietary restriction can improve learning in worms

A new study reveals that dietary restriction improves learning in worms by depleting a specific amino acid metabolite. The researchers used the nematode worm Caenorhabditis elegans to test how food deprivation affected learning and found that restricted access to food increased learning by reducing kynurenic acid levels.

Child abuse and neglect linked to gender inequality

Researchers found a significant association between gender inequity and increased child physical abuse and neglect. The study analyzed data from 57 countries and found that higher scores on measures of discrimination against women were linked to higher rates of child maltreatment.

Which type of cell to become: Decision through indecision

Researchers found that cell fate decision is not a unique programmed event, but rather the outcome of a dynamic process where cells explore different molecular possibilities before reaching a stable state. This process is reminiscent of trial-and-error learning and highlights the complexity of human hematopoietic cell fate commitment.

Magnetic quantum objects in a 'nano egg-box'

Researchers have successfully produced a 'quantum egg-box' with hundreds of thousands of artificially arranged fluxons, enabling stable non-equilibrium states. This breakthrough paves the way for developing fast computer circuits based on fluxons with enhanced speed and reduced heat dissipation.

Making lab equipment on the cheap

Neuroscientists have created a low-cost imaging and microscope system for research, training, and teaching, called FlyPi. The system uses 3D printing and open-source components to perform standard lab protocols at a fraction of the cost of commercially available solutions.

Does a candidate's religion matter to voters?

A new analysis by University of Houston political scientists found that party labels, not religious affiliation, are the most powerful predictors of how voters perceive candidates. Party brand matters more than a candidate's religious views when it comes to shaping voter beliefs about ideology.

Is teacher burnout contagious?

A new study by Michigan State University education scholars found that burnout among early-career teachers is contagious, with a stronger link to school-wide culture than close colleagues' burnout. The researchers analyzed survey data from over 400 teachers and found that schools can play a significant role in reducing teacher burnout.

Immune system cell clones created before birth may last for decades

Researchers found that identical twins share more T-cell clone receptors than expected due to potential exchange of T cells through cord blood before birth. This phenomenon suggests that some immune system cell clones created before birth can persist for about 40 years, shedding light on the diversity of T cell receptors in adults.

Training changes the way the brain pays attention

A study found that training enhances attention in the brain, leading to improved performance in tasks like reading x-rays and excelling in sports. However, after extended training, this initial gain in attention disappears, even though behavioral performance remains improved.

Infections in early life associated with increased risk for celiac disease

Recurring gastrointestinal infections in early childhood significantly increase the risk of developing gluten intolerance, according to a new study. The research found a strong association between early respiratory tract infections and an elevated risk of celiac disease.

How the brain recognizes what the eye sees

Researchers analyzed how neurons in V2 respond to natural scenes, discovering three principles: combining edges, cross-orientation suppression, and repeating patterns. This work provides insight into the brain's ability to recognize faces, cars, and other objects.
