The wonders of industrial agriculture have already given us the little red jewel that is the modern hot house tomato. They might look nice, but these plump, spongy fruits, bred to hold up in the truck, are tasteless. Now, scientists have a new trick in store for the tomato. They are working on a way to circumvent the tomato's natural need for rest and prodding tomato plants towards a full 24-hour growth cycle of staggering productivity.
Tomatoes, like most plants and animals, follow a circadian rhythm, a biological inner clock that tells them when to sleep and when to grow. But sleeping time is wasted time—so far as growers looking to maximize plant productivity are concerned—and, as Caleb Garling writes for Modern Farmer, geneticists have been hard at work trying to hack tomatoes into giving up their nap time.
According to new research, says Garling, geneticists have pinpointed a gene from wild tomatoes that deals how the plants handle light and have selectively bred it into modern hybrid tomatoes. This one little tweak caused a big jump in tomato productivity. The change, say the researchers in their study, “results in up to 20% yield increase, showing that limitations for crop productivity, caused by the adaptation of plants to the terrestrial 24-h day/night cycle, can be overcome.”

As streaming music gains popularity, record companies have insisted it’s not threatening their sales. But newly released statistics suggest that streaming music may be killing a format instead. For the first time ever, streaming revenues have surpassed those made by compact discs.
A new report from the Recording Industry Association of America shows that streaming outlets generated $1.87 billion in 2014—while CD sales fell to $1.85 billion. Streaming music’s edge is slight but significant: it now accounts for 27 percent of the industry’s total revenues. And while permanent downloads still dominate the digital music market (with $2.58 billion in revenues, they bring in about 38 percent more than streaming services), streaming is catching up quickly.
With digital music now capturing 65 percent of the market’s revenues, it’s easy to predict the demise of all physical formats. But there is one dark horse in the game. The RIAA’s report also showed that vinyl sales continue to rise (revenues are up 50 percent since 2013). LPs have staged what the Wall Street Journal calls “the biggest music comeback of 2014,” and the format is making gains with the same under-35 demographic that’s fueling streaming music.
The humble CD isn’t the only format that’s being edged out by a changing music market, either. Streaming music is threatening another mainstay: the car radio. The New York Post reports that terrestrial radio is being edged out by streaming services like Sirius XM and Pandora—and by 2018, more than 60 percent of new vehicles in the United States will come equipped with the technology it takes to stream on the go.
