Antioxidants are believed to have substantial health benefits and raspberries in particular are a good source. In fact, raspberries may have 10 times more antioxidants than tomatoes or broccoli. Further, raspberries contain some specific antioxidants that are found almost nowhere else.
In a study published in a recent issue of BioFactors, researchers from Plant Research International, Wageningen, The Netherlands, discuss specific compounds found in the berry, some appropriate methods for assaying the antioxidant concentration, and the biochemistry of antioxidant uptake in humans.
“Raspberries contain vitamin C and anthocanines,” says Jules Beekwilder, “but these can also be found in other products. However, approximately 50% of the antioxidant effect of raspberries is caused by ellagitannins. These you find in small doses in strawberries and practically nowhere else.” Some Chinese herbs may also be a source of these compounds.

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...
