Research by an EU-supported international team of scientists has shown that polychlorinated biphenyls (PCBs) - synthetic organic chemicals found widely in the environment and absorbed in the diet – may damage sperm.
But, lead author Dr Marcello Spanò, of the Italian National Agency for New Technologies, Energy and the Environment (ENEA), stressed that the study had found no dramatic effects on human fertility and had not revealed any serious public health threat. However, the findings were a warning and further research was needed.
The study, reported on line (Thursday 13 October) in Europes leading reproductive medicine journal Human Reproduction, also looked at dichlorodiphenyldichlorethylene (DDE) – a breakdown product of DDT – but found that it did not appear to damage sperm DNA.

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...

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...
