Nitric oxide is a natural part of the body’s immune defense. Linköping University researcher Thomas Schön has studied this compound in connection with the skin disease leprosy and the lung disease tuberculosis. The Swedish researcher has found that nitric oxide probably contributes to the disease in the case of leprosy but, on the other hand, plays a positive role in protecting against tuberculosis. This role can be reinforced by adding a supplement of arginine, which is found in peanuts, for example.
“The production of nitric oxide is high in both leprosy and tuberculosis patients. As regards leprosy, this nitric oxide can have a certain effect of killing off germs in the initial stages of the disease. But it does not always impede the development of the sickness, and in later stages it can even be seen as aggravating skin lesions,” says Thomas Schön.
He has run field studies in Ethiopia, a country where leprosy and tuberculosis often occur. In Ethiopia he studied the results of a synthetic dietary supplement of the amino acid arginine in tuberculosis patients. Arginine is needed to maintain the body’s production of nitric acid, and the supplemental arginine did in fact lead to a reduction of symptoms and a shorter contagious period among the Ethiopian patients.

New discoveries predict ability to forecast dementia from single molecule

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...
