As A Control Measure During Pandemic Outbreaks, School Closures Should Be Considered
Closing elementary and secondary schools can help slow the spread of infectious disease and should be considered as a control measure during pandemic outbreaks, according to a McMaster University led study. Using high-quality data about the incidence of influenza infections in Alberta during the 2009 H1N1 flu pandemic, the researchers show that when schools closed for the summer, the transmission of infection from person to person was sharply reduced... A Child's Long-Term Development May Be Harmed By Physical Punishment
An analysis of research on physical punishment of children over the past 20 years indicates that such punishment is potentially harmful to their long-term development, states an article in CMAJ (Canadian Medical Association Journal). Over the past 20 years, a growing body of research clearly indicates that children who have experienced physical punishment tend to be more aggressive toward parents, siblings, peers and, later, spouses, and are more likely to develop antisocial behaviour... Key To Immune Cell's 'internal Guidance' System Discovered
University of British Columbia researchers have discovered the molecular pathway that enables receptors inside immune cells to find, and flag, fragments of pathogens trying to invade a host. The discovery of the role played by the molecule CD74 could help immunologists investigate treatments that offer better immune responses against cancers, viruses and bacteria, and lead to more efficient vaccines. The findings are published in this week's edition of Nature Immunology...
