Just after Americans have headed to the polls to elect their next president, a new report in the November 13th issue of Current Biology, a Cell Press publication, reveals how one species of fish picks its leaders: Most of the time they reach a consensus to go for the more attractive of two candidates.
Despite the fact that household bleach is commonly used as a disinfectant, exactly how it works to fight bacteria remained an open question. Now, a report in the November 14th issue of the journal Cell, a Cell Press publication, provides an answer.
The two new studies reconstructed the Lancet review and the main conclusions of that reconstruction are:
Commercial broadcasters are doing the "bare minimum and not much more" for children's educational programming, according to University of Illinois communication professor Barbara Wilson, one of two lead researchers on a study released today (Nov. 12) by the organization Children Now.
The study was presented at a news conference at the National Press Club in Washington, D.C.
Fairfax, Virginia – November 12, 2008 – Ronald Reagan became one of history's heroes long before his death. But now his accomplishments are in danger of being oversimplified and distorted for partisan purposes. In a new article in Presidential Studies Quarterly, Hugh Heclo illustrates the deeper complexity of Reagan's legacy under eight headings of public concern: the Welfare State, Taxation, National Security, the Presidency, Personnel, Party Politics, Political Leadership, and the Person.
Washington, D.C. – November 12, 2008 – The HPV vaccine, sold as Gardasil in the U.S., is intended to prevent four strains of the human papillomavirus, the most common sexually transmitted infection in the world. The vaccine also prevents against cervical cancer. While the vaccine represents a significant public health advance, a new article in the Journal of Law, Medicine & Ethics suggests that it is premature for states to currently mandate the HPV vaccine as a condition for school attendance.
DURHAM, N.C. -- A new study led by Duke University researchers finds that restoring degraded wetlands -- especially those that had been converted into farm fields -- actually decreases their soil bacterial diversity.
But that's a good thing, say the study's authors, because it marks a return to the wetland soils' natural conditions.
Evidence that global warming is causing the worldwide declines of amphibians may not be as conclusive as previously thought, according to biologists. The findings, which contradict two widely held views, could help reveal what is killing the frogs and toads and aid in their conservation.
"We are currently in the midst of a sixth mass extinction event," said Peter Hudson, the Willaman professor of biology at Penn State and co-author of the research study. "And amphibians are bearing the brunt of the problem."
Scientists at Stanford University and Japan's National Institute of Informatics have created a new highly sensitive infrared spectrometer. The device converts light from the infrared part of the spectrum to the visible part, where the availability of superior optical detectors results in strongly improved sensing capabilities. The research will appear in the Nov. 24 issue of Optics Express, the Optical Society's open access journal.
More than half of people diagnosed with high blood pressure do not have it under control and many more go undiagnosed, according to research carried out at the University of Warwick.
Professor Franco Cappuccio from Warwick Medical School at the University of Warwick led the only UK team to participate in a European study examining awareness, treatment and control of high blood pressure, or hypertension. Hypertension is an important cause of serious diseases such as heart attacks and strokes.
