Polarized light pollution leads animals astray

A recent study published in Frontiers in Ecology and the Environment reveals that polarized light pollution can trigger animal behaviors leading to injury and death. Artificial light sources can attract or repulse animals, causing them to migrate incorrectly, choose poor nesting sites, or become trapped by reflective surfaces.

Women's access to donated kidneys declines with age, particularly compared with men

Younger women have equivalent access to kidney transplants as their male counterparts. However, older women receive transplants significantly less frequently than older men. The study found that for every age group analyzed, women had a similar or slightly higher survival benefit from transplantation compared to men.

Cost containment focus could have consequences for health care delivery

Physicians warn that assigning monetary value to every aspect of a doctor's time could impair quality and increase costs. Experiments show money-primed subjects are less willing to help others in need. A new trend in primary care, the 'patient-centered medical home,' aims to restore balance by compensating for unreimbursed time.

P2P traffic control

Researchers propose a wireless peer-to-peer network to exchange timely information about traffic conditions, incidents, and accidents. The Autonet system uses local-area wireless technology to form an ad hoc network that can handle measurements for approximately 3,500 traffic incidents.

Absence of CLP protein can be indicative of oral cancer

A new study published in the Journal of Prosthodontics found that the absence of Human calmodulin-like protein (CLP) in oral epithelial cells may indicate oral cancer. The researchers used staining to compare CLP expression in normal and cancerous tissues, revealing a significant decrease or complete lack of CLP in malignant regions.
