Researchers developed nanometer-sized semiconductor crystals that emit multiple colors of light, enabling the simultaneous measurement of several biological markers. These crystal probes show improved photochemical stability and fluorescence lifetime compared to conventional dye molecules.
The UCSF Dental Post-Bac Program aims to provide additional training to students from disadvantaged backgrounds who have been rejected from dental school. The program helps students develop the skills and knowledge needed to succeed in dentistry, with a focus on increasing access to dental care in underserved communities.
Hurricane Georges caused over 100 deaths and hundreds of millions of dollars in damage across the Caribbean. PAHO mobilized experts to provide emergency relief supplies and repair damaged health facilities.
A new animal study suggests that female mice exposed to DES in utero are at higher risk of reproductive tract cancers, while their unexposed offspring show no such increase. This finding indicates a potential transmission of susceptibility to cancer across generations.
Health ministers in the Americas call for urgent steps to regulate tobacco advertising and prevent minors' access, with a focus on educational, legislative, and fiscal measures. The region faces significant health and economic burdens due to tobacco use, with 670,000 deaths annually attributed to tobacco.
A major geomagnetic storm, the strongest in recent years, is affecting communication and navigation satellites due to an intense solar flare. The storm's speed was twice normal, causing unusual penetration of electrons into the Earth's magnetosphere.
Researchers John Toner and Yuhai Tu develop a theory explaining how birds move as a single unit despite frequent misjudgments and limited visibility. By making analogies to physics phenomena like magnet alignment and fluid flow, they provide insights into other animal collectives and even auto traffic flow.
