Researchers have developed a method to calculate how a device can provide maximum functionality with a minimum quantity of processor and memory capacity. TVs, DVD players and mobile phones can malfunction when the inbuilt chips and software cease to cope with the increasingly large flow of data.

Researchers have produced a first draft of the papaya genome. This draft sheds new light on the evolution of flowering plants. And because it involves a genetically modified plant, the newly sequenced papaya genome offers the most detailed picture yet of the genetic changes that make the plant resistant to the papaya ringspot virus.

It may not be an ideal topic for polite conversation, but human beings are swarming with bacteria: Even the average healthy adult plays host to about 100 trillion microscopic organisms. Infection takes place when the bacteria get out of hand. Now, a new history of the struggle between man and bacteria -- and warns that humankind someday may lose its advantage.

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.

Scientists have discovered what appears to be the primary driver of tumor development in the stomach. Inhibiting the signaling cascade initiated by the IL-11 protein prevented the development of inflammation, hyperplasia (an abnormal increase in the number of cells) and tumor formation in pre-clinical models of gastric cancer.
