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
A new way to identify the most malignant tumors in children has been identified by researchers. The method involves studying genetic ‘micro-variation’, rather than the presence of individual mutations. —> Read More Here
A genetic blueprint for organelles that give simple cells new functions has been developed by scientists. A research team has refuted a long-held assumption in biology: The scientists have shown that it is not only possible to extend the functions of organelles – organs of the cell – but also to form them from scratch with the help of genetic blueprints —> Read More Here
NASA’s Soil Moisture Active Passive (SMAP) spacecraft will be boosted into orbit aboard a United Launch Alliance Delta II rocket from Vandenberg Air Force Base in California. Learn how SMAP and the Delta II were readied for liftoff.
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 helicopter drone could help a rover on Mars to scout the terrain ahead and locate places of interest. One of the problems that a rover faces as it t… —> Read More Here
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.
LA JOLLA, Calif., Jan. 28 (UPI) — Scientists have managed to grow new hair from human pluripotent stem cells — cells capable of morphing into all sorts of different cells. —> Read More Here
Katrin Janhsen et al. show in their current review article in Deutsches Ärzteblatt International what is behind the high prescription volume of benzodiazepines in Germany and what needs to be considered for the purposes of withdrawal treatment in case of addiction. —> Read More Here
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
