Game theory explains social interactions of cancer cells

The interactions of cancer cells may be explained by using game theory. The Public Goods Game is part of game theory and is used in economics as a model to analyze the provision of common goods. There is an imbalance in the consumption of these goods between those that provide them and pay the production costs and those that do not pay but consume anyway — a situation that is known in economics as the free rider problem. The researchers now applied this model to the cooperation between producing and non-producing members of a cancer cell population, in order to examine if the model is also applicable to biological processes, such as carcinogenesis. —> Read More Here

New instrument to study the extreme universe — the X-Ray polarimeter X-Calibur

X-ray polarimetry promises to give qualitatively new information about high-energy astrophysical sources, such as black hole systems, the bright and active centers of galaxies, compact neutron stars, and gamma-ray bursts. The instrument will measure the polarization of 20-80keV X-rays. The detector is completed, tested, and fully calibrated and ready to be flown on a high-altitude balloon. —> Read More Here

A Hubble Sweep of the Dust Filaments of NGC 4217

In this image the NASA/ESA Hubble Space Telescope takes a close look at the spiral galaxy NGC 4217, located 60 million light-years away from Earth. The galaxy is seen almost perfectly edge on and is a perfect candidate for studying the nature of extraplanar dust structures — the patterns of gas and dust above and below the plane on the galaxy, seen here as brown wisps coming off NGC 4217.

Antibiotics as new cancer treatments? Conversation with schoolgirl sparks idea

A way to eradicate cancer stem cells, using the side-effects of commonly used antibiotics, has been discovered by a University of Manchester researcher following a conversation with his young daughter. “This is a perfect example of why it is so important to continue to invest in scientific research. Sometimes there are answers to some of the biggest questions right in front of us but without ongoing commitment to the search for these answers, we’d never find them,” said the lead researcher. —> Read More Here
