Scientists from the Flanders Interuniversity Institute for Biotechnology (VIB) have achieved a new breakthrough in cancer research. The researchers, connected to Ghent University, have discovered the function of an important mediator involved in suppressing the development of tumors. Using a mouse model, they have shown that absence of the mediator makes the mice susceptible to the development of cancer. Through this research, the scientists are contributing to a better understanding of the molecular mechanisms that control tumor development.
Cell cycle: a vital, controlled process in our body
Every day, the billions of cells that compose our body are being replaced: old cells die and new ones are produced. In the course of this process, each cell goes through a well-organized series of phases. First of all, the hereditary material, or DNA, in the cell nucleus is duplicated. Next, the nucleus divides itself in half; and then the entire cell divides, and the daughter cells grow into completely new cells. Because it is crucial that this cell cycle runs perfectly, various control points have been built in to enable the cell to control the stability of the DNA. If the DNA becomes damaged, the cell cycle will come to a stop.

What if, instead of turning up the thermostat, you could warm up with high-tech, flexible patches sewn into your clothes - while significantly reducing your...
A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.
Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
What if a sensor sensing a thing could be part of the thing itself? Rice University engineers believe they have a two-dimensional solution to do just that.
Rice engineers led by materials scientists Pulickel Ajayan and Jun Lou have developed a method to make atom-flat sensors that seamlessly integrate with devices...
