People who gain less protection from cancer by eating broccoli may be able to compensate for the difference in their genetic make-up by eating ‘super broccoli’, a variety with higher levels of the active plant chemical sulforaphane, or by eating larger portions.
Super broccoli developed by traditional plant breeding methods
Lead scientist on the new research, Professor Richard Mithen of the Institute of Food Research (IFR), said: “Eating a few portions of broccoli each week may help to reduce the risk of cancer. Some individuals, who lack a gene called GSTM1, appear to get less cancer protection from broccoli than those who have the gene.
“Our studies suggest that this may be because if you lack the gene you cannot retain any sulforaphane inside your body, it is all excreted within a few hours. However, if you consume larger portions of broccoli, or broccoli with higher levels of sulforaphane, such as the ‘super broccoli’, you may be able to retain as much sulforaphane in your body as those who have the gene. Eating larger portions may have additional benefits since broccoli is also a rich source of other vitamins and minerals”.

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.

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...
