Cowpea aphids (Aphis craccivora) are a major pest of cowpeas (Vigna unguiculata), which feed on the plant at the vegetative stage by sucking the sap. In an endeavour to find an new method of controlling aphid infestation in the Northern Ghana, an in vitro study was carried out to investigate the effect of different concentrations of aqueous false yam (Icacina oliviformis) tuber extract against cowpea black aphids (Aphis craccivora Koch).
The in vitro Studies of the Inhibitory Effect of Green Tea (Camellia sinensis) on Pseudomonas aeruginosa Treated Contact Lenses
Pseudomonas aeruginosa is the leading cause of ocular infections in those who wear contact lenses. Others have previously done a study using the antioxidant selenium-coated contact lenses to inhibit the bacteria in an animal model. However, selenium is very toxic even in small quantities. In this study, green tea which is known for its antioxidant property was used to treat contact lenses.

Beyond the Microscope: A Closer Look at the Work of Dr. James Reynolds
Dr. James Reynolds is a professor in the Department of Biomedical Sciences at Queen’s University. He also boasts an extensive, successful career in the field of pharmacology and neurotoxicology, and for the past 25 years, his central research focus has been the effects of alcohol on brain function. In particular, his current research project focuses on utilizing eye movement patterns to detect brain abnormalities predictive of developmental delays and brain injury in children.
Sleep Quality and Attention Deficit Hyperactivity Disorder
A study at the University of Toronto’s Institute of Medical Science, measured the correlation between sleep quality and the different subtypes of Attention-Deficit/Hyperactivity Disorder (ADHD). Researcher, Sun Young Rosalia Yoon, expected that sleep quality and ADHD would be correlated due to the effects of sleep deprivation, such as deficits in cognitive functions; such effects are also evident in those with ADHD.
Pig Chimeras Offer Glimpse of Future Human Organ Development
On January 26, 2017, a team led by Dr. Juan Carlos Izpisua Belmonte of the Salk Institute for Biological Studies successfully created pig embryos that had the potential to generate human organs. The team’s experimental results marked a key development in the artificial generation of chimeras, which are organisms that derive cells from various other embryos. Harnessing the full potential of artificial organ development would help many patients and hospitals that face organ donor shortages.
