A team of researchers is working on 3D-printing different organ cells, connecting them with a tiny circulatory system, and putting the whole thing on a two-inch chip, creating a "test subject" that's steps up from animals or single-organ cell groups.
Nitrous oxide makes up 38 percent of agriculture-based greenhouse gas emissions. Several new studies recommend wider development and production of a tropical "super grass" that binds nitrogen more effectively than other variations.
Clean Lahore was created in response to a 2011 epidemic that sickened 20,000. Along with a dedicated public health campaign, the app helps officials monitor all efforts to stop the disease's spread.
The change away from having to experience darkness, which we take for granted, is arguably one of the greatest disruptions of the natural order in the whole modern human experience.
It's the first time such conspicuous planning has been observed in the field -- in this case, Sumatra -- among non-human primates.
Nominated for an INDEX Award, David Swann's ABC Syringe changes color when it's exposed to air, thus providing a visual alert that it may be unsafe to use. The device could save more than a million lives each year.
Oxford University researchers have discovered a protein that prevents genes from adapting to differing levels of light. Suppressing this protein in mice caused their body clocks to adjust much faster.
A new study suggests that the necessary ingredients for life existed on Mars first, back when it was far more hospitable than it is now, and arrived here via a meteorite.
Sleep disorder specialists are calling attention to a new trend that, while less dangerous than sleep-driving, still represents a potential health concern.
American and European researchers are currently testing a procedure that uses generic fertility drugs and simpler equipment and could end up costing less than US$300.
Two Chalmers University of Technology students designed a nearly-all-steel chair with alternating seat positions that give users better leverage when navigating down unpaved roads and around other obstacles.
One spritz of Sprayable Energy onto the skin delivers the caffeine equivalent of a quarter-cup's worth of coffee. Developers Ben Yu and Deven Soni say they want to pitch it to people who are trying to regulate their intake.
Scientists at Duke University stimulated sensory neurons in a way that eventually allowed six rats to locate light signals that are invisible to the (unmodified) naked eye.
Thanks in part to a successful crowdfunding campaign, backers of the DrinkSavvy line -- glasses, cups, straws and stirrers that react to the presence of common "date-rape" drugs -- will start receiving the product next month.
More than 60 years after her death, Lacks' genetic material can no longer be used by researchers without family consent. Is the same true for the rest of us? Not exactly.
