Steel dust exposure in the NYC subway system has been of concern to subway workers and transit police for decades. A study by Lamont-Doherty Earth Observatory researchers will examine the level of airborne metal in subway workers. Photo credit: Mark Inglis
A pilot study gathers baseline information on subway workers’ exposure
by Jennifer Freeman
Working in the subway several hours each day, subway workers and transit police breathe more subway air than the typical commuter. Subway air has been shown to contain more steel dust than outdoor or other indoor air in New York City. But do transit workers’ bodies harbor elevated levels of these metals? And does this translate into a health concern for the workers?

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...
Over the last decade, there has been much excitement about the discovery, recognised by the Nobel Prize in Physics only two years ago, that there are two types...
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...
