A statewide study in Wisconsin found that unbelted crash occupants represented 68% of patients dying in emergency departments. Unbelted survivors were more than twice as likely to be admitted to the hospital and suffer moderate to severe injuries. The study also linked seatbelt non-use to higher ED bills and economic costs.
Women taking estrogen had fewer breast cancer tumors, but the difference was not statistically significant. Participants also underwent more mammograms and biopsies, which may be related to changes in breast tissue.

This active process can be treated with medications similar to those used for coronary artery disease, offering new options for prevention and treatment.
Researchers found that bacteria gain resistance through only a small fraction of the 120 possible mutational paths in a key gene. Most pathways fail to continuously improve resistance, contradicting traditional views on evolution by natural selection.

Researchers found that a 'dead zone' summer in Narragansett Bay led to the death of approximately 4.5 billion mussels, with filtering capacity dropping by 75 percent within weeks. The loss of such a foundation species has lasting effects on the ecosystem.
Modern ants arose between 140-168 million years ago, coinciding with the emergence of flowering plants. This shift provided new habitats and food sources for ants, allowing them to diversify and become dominant in terrestrial ecosystems.
A new Kent State group called the Center for Health Literacy aims to improve the health literacy of adults and families. The project will evaluate all aspects of the health information-seeking process and make recommendations to help health-related institutions craft more effective health information programs and services.
A study by Dr. Harrell found that young attractive female caretakers without rings lost sight of children 19% of the time, and young attractive males lost sight 25% of the time. The research suggests that an absence of emotional commitment to marriage or family may lead to neglect.
Scientists at the Woods Hole Research Center have developed high-resolution maps of the built environment for the Chesapeake Bay watershed, capturing impervious surface cover and its implications for biogeochemical and hydrological processes. The new maps are being used to assess water quality and inform restoration efforts in the region.
The pHLIP peptide accumulates in cell membranes at low pH and translocates molecules into cells without relying on traditional entry pathways. This technology has potential applications in imaging, diagnosis, and treatment of diseases associated with acidic environments.
Researchers found a statistically significant direct relationship between high cholesterol and prostate cancer. Men with prostate cancer were around 50% more likely to have had high cholesterol levels than non-prostate cancer controls, especially those diagnosed before age 50 or over 65.
A study using social comparison theory found that individuals are more likely to lie to those they know, particularly when their public image is threatened. This behavior is driven by a desire to protect one's self-image and self-worth, rather than purely strategic reasons.
Researchers found elevated antibodies to EBV in individuals with MS, persisting up to 20 years before symptoms. The study suggests a strong link between EBV and MS risk, but the exact mechanisms remain unclear.
A team of University of Michigan researchers used fMRI to capture the brain's instant response to costly mistakes. They found that the rostral anterior cingulate cortex (rACC) becomes more active when errors carry consequences, suggesting a key role in emotional responses and decision-making processes.
Diabetic patients undergoing periodontal therapy show improved metabolic control, with a 20% reduction in HbA1c levels. The study suggests that periodontal treatment may help diabetic patients move from the 'at-risk' category to a healthy range.
Researchers propose a new model of p53 regulation that suggests a novel anticancer strategy using Mdm2 and Mdm4. The study reveals that Mdm4 renders p53 inactive, while Mdm2 mainly controls the stability of p53's structure.

The malaria parasite affects antigen-presenting dendritic cells in mice, reducing their ability to activate helper T cells and produce cytokines. This impairment leads to the failure of B-cell activation and antibody production, compromising the immune system's response to infection.
The study refutes existing assumptions about inherent meaning in visuals, showing that creative directors and consumers share a similar understanding of white space. The researchers connect this to the minimalist movement and corporate art, highlighting the importance of socially agreed rules of language.
Researchers found that promotion-focused individuals prioritize their ability to follow through with healthy behaviors, while prevention-focused individuals prioritize the effectiveness of the behavior itself. This study has important implications for distributing information about healthy practices.
A new study finds that estrogen-only therapy does not increase the risk of breast cancer in postmenopausal women, contradicting previous findings. In contrast, hormone therapy combining estrogen and progestin was linked to a 26% higher risk of breast cancer.
Researchers found that chemotherapy improvements reduced recurrence risk by 21-55% in ER-negative tumors, while 9-26% in ER-positive tumors. This suggests that newer chemotherapies offer substantial benefits for patients with ER-negative disease.
