Many types of cancer–like those of the breast and prostate–would not be nearly as deadly if it werent for their ability to spread to vital organs. Still, scientists dont yet fully understand the way in which cancer spreads, or metastasizes, or how to prevent the process.
Now, researchers at the San Francisco VA Medical Center (SFVAMC) have used a modified version of a naturally occurring human protein to decrease the spread of human breast cancer implanted in mice.

By analyzing data on tree pollen extracted from ancient lake sediments, ecologists have sharpened the understanding of how forests can maintain a diversity of species. Their findings indicate that stabilizing processes have been more important than previously thought, and that the human-caused loss of species could upset that stability in ways that remain poorly understood.
“Quantifying the link between stability and diversity, and identifying the factors that promote species diversity, ha
Exhaust from the main engines of NASA’s space shuttle, which is about 97 percent water vapor, can travel to the Arctic in the Earth’s thermosphere where it forms ice to create some of the Earth’s highest clouds that literally shine at night, according to a new study led by the Naval Research Laboratory and jointly funded by NASA and the Office of Naval Research.
The thermosphere is the highest layer in our atmosphere, occupying the region above about 55 miles (88 kilometers) altitude. The c
A completely new way of killing the malaria parasite has been found by researchers at St George’s Hospital Medical School in London. Professor Sanjeev Krishna’s research group is world-renowned in the battle against infectious diseases and has now discovered how to stop the malaria parasite’s sugar transport protein from working. This prevents the parasite growing and multiplying in the red blood cells where it lives. The research is published this week in the Proceedings of the National Academy of S
Oxford scientists have discovered a particularly macabre method one parasite (Strepsiptera) has for disguising itself in its insect host: it wraps itself in a piece of the host’s own body tissue. In this way the strepsipteran masquerades as ‘self’, and is protected from the insect’s immune system.
The mechanism whereby Strepsiptera flourish without interference from the host has so far been a mystery. Scientists have been intrigued by the exceptional diversity of host insects exploited by th
Penn State researchers have developed new software that can help decision-making teams in combat situations or homeland security handle information overload by inferring teams information needs and delivering relevant data from computer-generated reports.
The agent software called CAST (Collaborative Agents for Simulating Teamwork) highlights relevant data. This helps improve a teams decision-making process as well as enhances members collaboration.
