Regenstrief, IU study: Caregivers open to stopping cancer screening as dementia progresses

A study found that many family caregivers of older adults with dementia are willing to consider stopping cancer screening, which can reduce patient burden, healthcare costs, and family caregiver distress. Caregivers are most open to discussions when focusing on quality of life and burdens and benefits for the person with dementia.

Rice researchers part of new LHC discovery

Researchers at Rice University have made a significant contribution to the Large Hadron Collider's (LHC) latest discovery, confirming the Standard Model's prediction of the rare B-sub-s meson decay. This finding eliminates any possibility that the decay is related to dark matter theories, such as supersymmetry.

The genetic key to conquering cholera

A team of Harvard scientists has identified genetic areas in the genome that may help protect against cholera by regulating immune system functions and fluid loss. The study's findings suggest a new approach to understanding host immunity and developing vaccines and therapies for this deadly disease.

Overnights away from home affect children's attachments, U.Va. study shows

A new national study by University of Virginia researchers found that infants spending at least one night per week away from their mothers had more insecure attachments compared to those with fewer overnights or staying with fathers during the day. This raises concerns about the impact of parental separation on children's emotional con...

Purple sunlight eaters

A protein found in ancient microorganisms that live in desert salt flats has been combined with semiconducting nanoparticles to create a system that uses light to spark a catalytic process creating hydrogen fuel. This bio-assisted hybrid photocatalyst outperforms many other similar systems in hydrogen generation.

Electronic health records help fight vaccine-preventable diseases, Columbia Nursing study finds

A study by Columbia Nursing researchers found that automated reporting of immunization data through EHRs increased knowledge about individuals and communities, allowing medical and public health officials to make informed decisions. This led to reduced lag times, improved documentation, and enhanced efficiency in vaccine tracking.
