Addressing inequity in air quality

Researchers are using satellite and ground-based tools to measure air quality, revealing significant differences in nitrogen dioxide levels between majority white and minority communities. This study aims to inform policymakers about the need to mitigate inequity in air pollution, which disproportionately affects communities of color.

Single dose of Pfizer or Astra Zeneca COVID-19 vaccine offers substantial protection to

A single dose of either the Pfizer or Astra Zeneca COVID-19 vaccine offers around 60% protection against infection from SARS-CoV-2 in residents of long-term care facilities aged 65 and over. Vaccination also reduces the risk of transmission and infectivity, with a protective effect evident from 4 weeks after vaccination.

Recycling of the eye's light sensors is faulty in progressive blindness of older adults

A study published in Nature Communications found that the process removing old light sensors is disrupted in progressive blindness, leading to age-related macular degeneration. The researchers identified mTORC1 as a key component involved in photoreceptor recycling and suggest potential treatments using drugs against mTORC1.

Combining three techniques boosts brain-imaging precision

Researchers developed a trimodal approach combining functional MRI, electroencephalography, and EROS to capture timing and location of brain responses with higher precision. The method provides a clearer picture of how different parts of the brain activate and communicate when an individual is distracted or engaged in a cognitive task.

Predicting tooth loss

Researchers developed machine-learning tools to predict tooth loss based on medical characteristics and socioeconomic factors, outperforming traditional clinical indicators. The approach could be used globally to screen people and improve early interventions, potentially delaying or preventing tooth loss.

Cancer survivors' tongues less sensitive to tastes than those of healthy peers

Researchers at the University of Illinois found that cancer survivors' tongues are significantly less sensitive to bitter, salty, or sweet tastes due to damage caused by radiation therapy. The team discovered that taste dysfunction persists for years after treatment ends, affecting the quality of life for these individuals.

Wild bees need deadwood in the forest

A recent study published in Forest Ecology and Management found that creating deadwood in coniferous forests can promote the abundance of aboveground nesting bees. The researchers created artificial structures with standing timber in six sample plots in the Black Forest National Park, leading to an increase in wild bee populations.

Mongooses solve inequality problem

A new study on banded mongooses found that providing extra food to mothers created initial size disparities among pups. However, the well-fed mothers then provided more care to smaller pups, reducing these differences and promoting fairness in pup survival.

Increased organizational support for employees' adoption efforts yields positive benefits

A Baylor University study found that organizational support for adoption positively affects employees, their families, and the organization itself. The research showed that commitment to the organization is greater when employees receive financial reimbursement or leave policies supporting their adoption of a child.
