Discovery has implications for future treatments
Researchers at the University of Minnesota have identified for the first time a group of genes that impact the development and function of blood stem cells, a discovery that brings researchers a step closer to harnessing the power of stem cells for disease treatments.
Every day, blood stem cells divide and differentiate to generate approximately 200 billion new blood cells in the bone marrow of adults. To maintain their numbers over time, blood stem cells also can divide and give rise to new blood stem cells through a process called self-renewal. What was not fully understood is which genes control the self-renewal and differentiation processes, and how these genes could be used to influence, or regulate, these processes.

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...
