Purple hydrants carry purified wastewater, mostly intended for landscaping.
In California's Silicon Valley, there will soon be a new source of water for residents. That may not sound like big news, but the source of this water – while certainly high-tech — is raising some eyebrows.

The question of how humans process the flood of electronic media was a central part of the work of Stanford University sociology professor Clifford Nass, who died recently. Citing multiple studies, Nass said people often overestimate their ability to multitask.
Clifford Nass, the Stanford University sociologist who helped pioneer studies that undermined ideas about multitasking, has died at age 55. The man who dedicated his career to thinking about how humans live in a digital age died after taking part in a hike near Lake Tahoe Saturday.

If the Food and Drug Administration has its way, an era of food technology will soon end. The agency announced Thursday it is aiming to ban partially hydrogenated vegetable oils from all food products.

If the agency makes this decision final, it will mean a complete ban on this ingredient.
