The Empire State's orchards are being carpeted with red as fruit is left to drop to the ground.
In this case a Roomba, that autonomous robotic vacuum cleaner, did the same, but with a venomous viper in Israel.
Today, he and his colleagues published a paper in the New England Journal of Medicine about a new way to slow and possibly even stop the progression of type 1 diabetes, also known as juvenile-onset diabetes.
The approach uses the drug Rituxan, normally indicated to treat non-hodgkins lymphoma and rheumatoid arthritis.
"What this study does is open the door to a whole new way to approaching type 1 diabetes," Dr. Mark Pescovitz of Indiana University, who led the study, said in a telephone interview.
Rituxan, known generically as rituximab, is made by Genentech, a unit of Roche Holding AG and Biogen Idec Inc. It was designed to wipe out immune cells known as B lymphocytes, which proliferate out of control in lymphoma.
The same cells are also involved in the autoimmune destruction of healthy cells and tissue seen in rheumatoid arthritis and, in theory, in juvenile diabetes.
Usually, by the time diabetes symptoms appear, 80 to 90 percent of those insulin-producing cells have been destroyed. The Pescovitz team gave Rituxan hoping to save the remaining cells.
The treatment worked at first and the body produced more insulin. But over time, the effects faded, and insulin production began to decline at the same rate as among people who received placebo.
Pescovitz said he was not disappointed. Further tests will show if repeated treatments with Rituxan or newer drugs that also eliminate B lymphocytes will keep insulin production up.
After decades of seeing plants as passive recipients of fate, scientists have found them capable of behaviors once thought unique to animals. Some plants even appear to be social, favoring family while pushing strangers from the neighborhood.
Research into plant sociality is still young, with many questions unanswered. But it may change how people conceive of the floral world, and provide new ways of raising productivity on Earth’s maxed-out farmlands.
“When I was in school, researchers assumed that some plants were better or worse than others at getting resources, but they were blind to the whole social situation,” said Susan Dudley, a McMaster University biologist. “I went looking for it, and to my shock, found it. And we’ve found more of it since.”
In a paper published in the November American Journal of Botany, Dudley describes how Impatiens pallida, a common flowering plant, devotes less energy than usual to growing roots when surrounded by relatives. In the presence of genetically unrelated Impatiens, individuals grow their roots as fast as they can.
A hammerhead shark's unusual shape gives it outstanding vision, according to a study which may solve a centuries-old mystery.

Unusually warm and cold spells in climate history are linked to how oceans responded to temperature changes, a study says.
Here's the latest:
The United States government might have a bigger budget to work with -- if one bodybuilding governor would pay the back taxes it appears he never got around to paying.
According to documents filed in L.A. County Superior Court, Arnold Schwarzenegger owes the IRS $39,047 from 2004 and $40,016 from 2005.
In total the Guv owes $79,064.00 ... and as we all know, he's definitely not saving the money for rainy day traffic violations.
An official at the L.A. County Recorder's Office said their system shows the lien is still active.

Good, because the universe is willing to help.
Right now the stars are anything but short on creative ways to enjoy the company of others -- and they just so happen to have set up shop in your house of entertaining.
How about having the whole crew over to your place for pizza, movies and games?
