(Cell Transplantation Center of Excellence for Aging and Brain Repair) Researchers suggest that stromal cells derived from menstrual blood may represent a potentially unlimited, ethically unencumbered, easily collectable and inexpensive source of stem cells for use in regenerative medicine. The study found that MenSCs are easily expandable to clinical relevance and express multipotent markers at both the molecular and cellular level. The abundance and plasticity of MenSCs suggest a potential role for MenSCs in regenerative transplantation therapies for many different organs and tissues.

(Alliance for Green Revolution in Africa) As concern builds around the impact of rising food prices and new restrictions on rice exports from Asian countries hit by adverse climate conditions, the Alliance for a Green Revolution in Africa announced today that African rice breeders have made critical steps towards ensuring self-sufficiency and boosting African rice production. The successful development and release of stress-tolerant upland and lowland irrigated rice varieties has begun to significantly increase rice production in some countries, including Uganda.

String-like connections found between T-cells could be important to how HIV spreads between cells in the human immune system, according to new research published online in Nature Cell Biology. The newly-discovered strands, named “membrane nanotubes” by scientists, could help to explain how the HIV virus infects human immune cells so quickly and effectively.

With inspiration from bacteria and butterflies, researchers at Stockholm University have developed a new method that shows how nanomaterials can be produced in the future. In an article in Proceedings of the National Academy of Sciences, Professor Lennart Bergström shows how a glass bottle and a simple hobby magnet can be used to produce and arrange extremely small cubes of iron oxide in a perfectly checkered pattern.
