UAF geologist studies Chicxulub impact crater

01-17-2007 · EurekAlert!

About 65 million years ago, a massive disruption led to worldwide extinction of dinosaurs. The impact of a giant asteroid created massive tsunamis and spewed forth a global cloud of carbon gases that altered Earth's atmosphere and blocked the light for weeks, possibly years. In recent years, that impact event has been linked to a 112-mile-wide crater, dubbed Chicxulub, on the coast of Mexico's Yucatan Peninsula.

Workplace bullying 50 percent higher in the US than Scandinavia
05-29-2007 · EurekAlert!
New research to be published in Journal of Management Studies reveals that US employees are bullied up to 50 percent more often than workers in Scandinavia. However, just 9 percent of employees are aware that negative acts they experience constitute bullying, suggesting that bullying behaviour is ingrained in US workplace culture. The study is one of the first to investigate the impact of bullying on non-bullied employees, and finds employees witnessing others being bullied suffer secondary harm.

Journal Sleep: Chronic insomnia can predict future functioning of adolescents
02-01-2008 · EurekAlert!
In one of the largest epidemiologic studies of insomnia among adolescents ever conducted in the United States, a study published in the Feb. 1 issue of the journal SLEEP allows for an estimation of the impact of chronic insomnia on future functioning of adolescents. Youths with insomnia, particularly chronic insomnia, are at greater risk of future somatic and especially psychological problems, the study found.

Seismic images show dinosaur-killing meteor made bigger splash
01-23-2008 · EurekAlert!
The most detailed 3-D seismic images yet of the Chicxulub impact crater may modify a theory explaining the "KT Extinction Event" that wiped out most life on Earth, including the dinosaurs. According to research appearing in Nature Geosciences, the asteroid landed in deeper water than previously assumed and therefore released about 6.5 times more water vapor into the atmosphere, possibly making it deadlier by altering climate and generating acid rain.

Columbia research explores impact of gum disease therapy on pregnancy
11-01-2006 · EurekAlert!
A study published in the New England Journal of Medicine shows that treatment for periodontal disease in pregnant women does not result in a lower rate of adverse pregnancy outcomes such as preterm birth and low birth weight. At the same time, the study showed that periodontal treatment during pregnancy is safe. The researchers recommend additional studies to assess the potential benefits of the treatment.

MGH study examines impact of infection with both HIV and hepatitis C virus
12-11-2006 · EurekAlert!
In a report in the December issue of PLOS Medicine, a group of researchers from the Partners AIDS Research Center at Massachusetts General Hospital report one of the first studies of how HIV infection impacts immune system functions involved with hepatitis C virus control. Their findings suggest that beginning antiretroviral therapy earlier than is generally recommended may help preserve HCV control in patients infected with both viruses.

Low impact aerobic exercise reduces fatigue in auto-immune conditions says multi-study review
11-29-2006 · EurekAlert!
People with auto-immune conditions like MS, arthritis and lupus can benefit from low impact aerobic exercise -- including walking and cycling -- that increases in intensity, duration and frequency. A review of studies between 1987 and 2006 shows that 12-week programmes that involved exercising for 30 to 60 minutes, three times a week, yielded the most effective results.

Study led by Scripps Research scientist reveals little-known cell networks vital to circadian rhythm
05-03-2007 · EurekAlert!
In a wide-ranging systems biology study of circadian rhythm, a multi-institutional collaboration led by Scripps Research Institute Professor Steve Kay has uncovered some little-known cellular mechanisms for sustaining circadian rhythm and limiting the impact of genetic clock mutations in mammals. The new findings could have important implications for future circadian studies, and point researchers toward new ways to manipulate human circadian rhythm at the molecular level to treat diseases such as bipolar disorder.
