WEST LAFAYETTE, Ind. - Just as no two humans are the same, a Purdue University scientist has shown treating mice more as individuals in laboratory testing cuts down on erroneous results and could significantly reduce the cost of drug development.
Mice have long been used as test subjects for treatments and drugs before those products are approved for human testing. But new research shows that the customary practice of standardizing mice by trying to limit environmental variation in laboratories actually increases the chance of getting an incorrect result.
INDIANAPOLIS – A study published in the April 2009 issue of the medical journal Acta Pædiatrica is the first to report that birth defect rates in the United States were highest for women conceiving in the spring and summer. The researchers also found that this period of increase risk correlated with increased levels of pesticides in surface water across the United States.
University of Minnesota researcher Christine Greenhow, Seattle-based news aggregator NewsCloud and student newspaper The Minnesota Daily today announced the launch of the Minnesota Daily Facebook application. The Minnesota Daily application aims to become the hub of news and sharing for U of M students and community, combining both professional student and citizen journalism. Researchers will use it to test new ways to engage youth in news and information through social media.
Nearly undetectable from the ground, unmanned aerial vehicles (UAVs) are widely used by the military to scan terrain for possible threats and intelligence. Now, fuel cell powered UAVs are taking flight as an Office of Naval Research (ONR)-sponsored program to help tactical decision-makers gather critical information more efficiently… and more quietly.
Gastric cancer (GC) is one of the most common malignancies in the world with a high incidence and death rate. TNM staging system is used worldwide to predict prognosis and direct therapeutic decisions of patients with GC. However, the prognoses of patients with stage 2 and 3 GC are more heterogeneous and less predictable by staging criteria. Therefore, finding molecular markers that are able to predict the potential of tumor recurrence and prognosis of patients is extremely important for appropriate individualized therapy.
ATLANTA — In the midst of life-threatening situations requiring split-second decisions, police officers with a higher ability to multitask are less likely to shoot unarmed persons when feeling threatened during video simulations, a new Georgia State University study suggests.
Heather Kleider, Dominic Parrott and Tricia King, assistant professors of psychology at Georgia State, have taken a unique look at officer-involved shooting situations, signs of negative emotions and working memory capacity — the capacity to perform multiple mental tasks, such as reasoning, at the same time.
When animals in southern Africa are sick, often the first place their caretakers look for help is from native plants.
That's what makes understanding and conserving these plants so important, according to a group of Kansas State University researchers who are learning more about the uses of such plants in veterinary medicine.
"Our idea is to bridge the disciplines of anthropology, veterinary medicine and ecological conservation," said Ronette Gehring, assistant professor of clinical sciences at K-State's College of Veterinary Medicine.
