Hertel’s team is currently working on the next step necessary for many biomedical uses: finding a way to attach molecules to the su...

Plants recognize their siblings, biologists discover

...t that the docile garden plant isn’t as passive as widely assumed, at least not with strangers. Researchers at McMaster University have found that plants get fiercely competitive when forced to share their pot with strangers of the same species, but they’re accommodating when potted with their siblings.

"There is also a need for new and widely accessible methods for detecting HIV infection in infants, whether resistant or not," he pointed out, "since transplacental transfer of maternal antibodies precludes the use of antibody detection methods." Affordable techniques also are necessary to...

Statin treatment improves spatial memory in mouse models of Alzheimer's

...reatment with Simvastatin, one of the statin drugs widely used for lowering cholesterol in humans, significantly improved spatial memory - how to navigate a water maze - in mice genetically bred to have an Alzheimer’s like disease. Although statin improved memory in both males and females, the results were ...

Mice with a migraine show signs of brain damage
