According to a new study, corporate directors, who are ultimately responsible for internal whistle-blowing systems, often do not take action at all regarding anonymous allegations, even when the allegation involves very serious accounting breaches. However, if an identical non-anonymous allegation surfaces, audit committees often launch into action and the corporate director allocates significant resources to the investigation at hand.

A team of scientists led by Eugenia Kumacheva of the Department of Chemistry at the University of Toronto has discovered a way to predict the organization of nanoparticles in larger forms by treating them much the same as ensembles of molecules formed from standard chemical reactions.

Afrucannational parks like Masai Mara and the Serengeti have seen populations of large mammals decline by up to 59 pe cent, according to a study published in Biological Conservation.

Nutrition experts at Oregon State University have essentially "cured" laboratory mice of mild, diet-induced diabetes by stimulating the production of a particular enzyme.

Published research provides insights into the early importation of tortoises and the changing attitude of British society towards family pets.

When a star explodes as a supernova, it shines so brightly that it can be seen from millions of light-years away. One particular supernova variety -- Type Ia -- brightens and dims so predictably that astronomers use them to measure the universe's expansion. The resulting discovery of dark energy and the accelerating universe rewrote our understanding of the cosmos. Yet the origin of these supernovae, which have proved so useful, remains unknown.

New research finds that a history of sexual abuse, regardless of the victim's gender or age when the abuse occurred, correlates strongly with a lifetime diagnosis of multiple psychiatric disorders.

Cognitive psychologists have shown that an image displayed too quickly to be seen by an observer can be detected if the participant first hears the name of the object.

A new study by researchers from the John Theurer Cancer Center at Hackensack University Medical Center sheds light on how bortezomib, the first in a new class of cancer drugs known as proteasome inhibitors, works in mantle cell lymphoma. The study also provides preliminary evidence for which patients might benefit most from bortezomib. Additionally, researchers demonstrate that biomarkers -- the genes and proteins that indicate biological processes -- might help guide the selection of patients for specific clinical trials and speed-up the development of targeted cancer drugs. The study, which is now published online, will also appear in the July issue of Leukemia and Lymphoma.

A team of investigators has identified a series of proteins that might make it easier for doctors to better diagnose the more metastatic forms of prostate cancer.

Nearly 1 out of every 25 restaurant-associated food-borne outbreaks with identified food sources between 1998 and 2008 can be traced back to contaminated salsa or guacamole, more than double the rate during the previous decade, according to research released by the Centers for Disease Control and Prevention today at the International Conference on Emerging Infectious Diseases.

Hospitals still struggle to prevent avoidable healthcare-associated infections, according to a survey of infection preventionists released today by the Association for Professionals in Infection Control and Epidemiology. Half of those surveyed agree that catheter-related bloodstream infections continue to be a problem in their facilities and cite lack of time, resources, and the commitment of hospital leadership as hindering their ability to combat these infections more aggressively.

Approximately one out of every four people observed in a public setting failed to cover their mouth when they coughed or sneezed according to research presented today at the International Conference on Emerging Infectious Diseases. Even more concerning, less than 5 percent of people covered their mouth using methods recommended by public health officials.

Canada needs a national approach to funding drugs for rare diseases and can learn from other countries, states an analysis article in CMAJ.
