Tap water is indisputably a more environmentally-friendly drinking choice than bottled water. But now, rising levels of pharmaceuticals in the water supply are raising concerns about the safety of the tap.
This situation has prompted four Chemical Engineering students at Ryerson University in Toronto, Canada to design a wastewater treatment system that could remove 90 percent of pharmaceuticals and other potentially harmful compounds.
For those of you who have cheered on the Fighting Irish, we now bring you: the Fighting IBots! Every year at the University of Notre Dame, about 70 Mechanical Engineering students put together two teams of rugged, remote-controlled robots that compete in an exciting football match. See a video of last year’s game day after the jump.
No one has conversed with Eric Ramsey since 1999, when a car crash paralyzed him, leaving his conscious mind trapped inside an unresponsive body. The rare condition is called locked-in syndrome, and it has left Ramsey unable to even blink. But now, scientists and engineers are helping him reconnect with the outside world.
Five years after the incident, scientists implanted a device in his brain linking it directly to a speech synthesizer. After years of practice, Ramsey can now generate vowel sounds just by thinking of them.
