Understanding molecular double action of tzds to reduce side effects
In an attempt to find a new generation of diabetic drugs that will minimize side effects, researchers at the University of Pennsylvania School of Medicine report a new understanding of how thiazolidinediones (TZDs), widely used diabetic medications, work in fat cells. With yearly sales exceeding billions of dollars, TZDs – such as rosiglitazone maleate (Avandia) and pioglitazone hydrochloride (Actos) – help to maintain diabetics blood-sugar levels.
In fat cells, TZDs turn on a small set of genes, which arent normally turned on, by targeting the receptor PPARã. To tease out how the medications work specifically, the investigators set out to determine the difference between the genes that are ordinarily turned on in fat cells and the genes that are turned on only when diabetics are given the TZDs.

Researchers from the University of Basel have reported a new method that allows the physical state of just a few atoms or molecules within a network to be controlled. It is based on the spontaneous self-organization of molecules into extensive networks with pores about one nanometer in size. In the journal ‘small’, the physicists reported on their investigations, which could be of particular importance for the development of new storage devices.
Around the world, researchers are attempting to shrink data storage devices to achieve as large a storage capacity in as small a space as possible. In almost...
The more objects we make "smart," from watches to entire buildings, the greater the need for these devices to store and retrieve massive amounts of data quickly without consuming too much power.
Millions of new memory cells could be part of a computer chip and provide that speed and energy savings, thanks to the discovery of a previously unobserved...

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...
