Learning From Lyme

Since its discovery in 1975, Lyme disease has become one of the most commonly reported diseases transmitted by insects, spiders or other arthropods. Declining biodiversity may be a contributing factor in the rise of Lyme disease in humans. Explore this unexpected consequence of human impact on animal habitats in this new Science Bulletins feature.

Surveying Vietnam

In recent years, scientists from around the world have turned to Vietnam in their search for new plant and animal species. Vietnam harbors an astonishing range of habitats, from rain forests and dry forests to mangroves and coral reefs. Scientific expeditions and surveys have discovered an amazing range of biodiversity. But even as this biodiversity is being revealed, it is coming under threat from development and human activity. Scientists now are racing to accomplish their studies in an effort to keep Vietnam's biological wealth from disappearing entirely.

The Ecology of Climate Change

The boreal forest, which stretches across northern latitudes just south of the Arctic Circle, is a key region for studying climate change—and not just the impacts. Follow ecologists into Alaska's boreal forest to learn more in this new Science Bulletins video.

Attachment Theory: Understanding the Essential Bond

In 1958, psychologist John Bowlby pioneered "attachment theory," the idea that the early bond between parent and child is critical to a child's emotional development. Since then, scientists have discovered that insecure attachment during formative years can significantly stress both the developing brain and body, resulting in long-term psychological and physical ailments. For example, low levels of attachment security have been linked to diminished levels of cortisol, a steroidal hormone released in response to stress that is critical in reducing inflammation in the body. Watch the latest Human Feature from the Museum's Science Bulletins program to see how recent studies are using cortisol levels as a marker to determine the success of early intervention in building stronger attachments between struggling parents and children. Visitors to AMNH may view the video in the Hall of Human Origins until January 2, 2012.

Monitoring Mount Etna: Magma on the Move

Monitoring Mount Etna: Magma on the Move

Scientists in Sicily are collecting an enormous amount of data to monitor moving magma inside Mount Etna, one of the most active volcanoes in the world. Nearly a million people live on the volcano's flanks, so being able to predict an eruption could be a matter of life and death. In this Earth Bulletin, visit the volcano's snowy slopes and learn how scientists from the Italian National Institute for Geophysics and Volcanology record seismic activity, measure gases seeping up through the ground, sense the volcano's temperature changes, and assess disturbances in gravitational and magnetic fields to predict eruptions weeks ahead of time.

Archived in Ice: Rescuing the Climate Record

Follow scientist-adventurer Lonnie Thompson to the 5,670-meter-high Quelccaya ice cap in the Peruvian Andes. Thompson and his team from Ohio State University are racing to core a cylinder of 1,500-year-old ice to unravel the past climate patterns of this region - before our gradually warming climate melts this invaluable record away. By analyzing global ice cores, glaciologists like Thompson now have a well-preserved record for 150,000 years of climate history, allowing us to better predict future climate change.

On Shaky Ground: Building a Safer Future in Haiti

On Shaky Ground: Building a Safer Future in Haiti

In November 2010, ten months after a magnitude 7.0 earthquake flattened huge sections of Port-au-Prince, Haiti, a team of geologists commissioned by the United Nations set out to make the first detailed soil map of the city. Armed with sledgehammers and vibration sensors, the scientists surveyed how soils throughout Port-au-Prince either amplify or muffle seismic vibrations. The resulting map can now be used to guide reconstruction efforts. In this Science Bulletins feature, learn how geologists and engineers in Haiti and San Francisco are improving our resilience to powerful shifts of Earth's crust.
