0112_NextPinot noir enthusiasts have another reason to rave about their beloved red wine: The grapes of the famous cultivar may be a little bit smarter than some other varieties.  According to Laurent Deluc, an Oregon State University horticulturist, individual grapes on a pinot cluster ripen at different rates, yet somehow they all end up mature at harvest. That “catch up” mechanism contrasts with Zinfandel, “a famous uneven ripener,” says Deluc, who conducted the pinot research at OSU’s Woodhall Vineyard.  At the onset of ripening, his team identified four different berry classes on the same cluster: green hard berry, green soft berry, pink soft berry and red soft berry. Then they looped color-coded strings around individual grapes to track their development and found they all eventually ended up in the same class. Positing a genetic trigger, Deluc says the mature berries may be sending a “hurry up” message to their under-ripe siblings. The next step is to develop a model to help industry identify the best time for harvest, says the French Deluc, adding that the gap in knowledge in the field of grape ripening has frustrated him for 10 years. “When I was in the Ph.D. program, I said, ‘One day when you become a researcher, you will study this aspect.’”

But whether you choose classic tortiseshell or aviator chic, please, shed the sunglasses when you walk in the door — and, of course, at night.

Oregon already ranks as the nation’s second largest generator of hydroelectric power. (Washington is No. 1). Now an elegant new installation in Portland is putting an unconventional, sharing economy twist on this age-old water-energy pairing. The new system, launched this winter, uses the flow of water inside city water pipes to spin four turbines that produce electricity for Portland General Electric customers.

As a general rule, the more people with autism can be provided with visual cues, the better they will be able to understand and manage their environment. It’s a lesson Tom Keating learned well. The 61-year-old Eugene grant writer spent 31 years taking care of his autistic brother James, and in the late 1980s developed a spreadsheet that created a series of nonsense characters that grew or shrank depending on how much money James had in his account.
