Chen receives Guggenheim fellowship

Dr. Chen will use his Guggenheim Fellowship to research the structures and properties of ferroelectric and multiferroic thin films with potential applications in various functional devices. He aims to develop theories and multiscale computational models for predicting their behaviors.

'Wonderful' star reveals its hot nature

The Chandra X-ray Observatory has observed an X-ray outburst from the highly evolved red giant star Mira A, revealing a bridge of hot matter streaming between it and its companion white dwarf. The detection provides insights into interactions between binary systems, including those with a collapsed star.

The state of river restoration in the US

Researchers from eight universities and conservation groups compiled a comprehensive database on nationwide river restoration projects, analyzing over 37,000 current projects. The study found that most projects were implemented in the Pacific Northwest or Chesapeake Bay watershed and had median costs of $57,000 in Georgia.

River restoration field booms, matures

The river restoration field has matured into a science, with the nation's first comprehensive database of projects documenting trends and progress. Key findings include exponential growth in restoration efforts, with $14-15 billion invested since 1990, and a need for consistent monitoring to improve future efforts.

Lower vaccination rates put children at risk

A study found that 35% of children using complementary alternative medicines (CAM) had lower vaccination rates, while 8.9% were unvaccinated for diseases like measles, mumps, and rubella. Parents' misconceptions about vaccine safety can lead to adverse events and harm their children.

AGU journal highlights - 27 April 2005

New research models long-term climate cycles like El Nino, finds molten rock makes big earthquakes bigger, and sheds light on Yellowstone's volcanic activity. A computer simulation produced El Nino-like climate cycles, while another study found that melted rock accelerates plate movement during earthquakes.

'Live fast, die young' true for forests too

A USGS study reveals that the world's most productive forests, which add new growth each year, have lower birth and death rates. However, if these rates suddenly stop or double, tree numbers would halve in just 30 years. The study suggests that environmental changes considered beneficial to forests may bring about unexpected changes.
