There are 8 million iPads in the classroom, but only a few thousand studies of their effectiveness.
The Army sergeant spent five years as a captive of the Taliban. He arrived at Brooke Army Medical Center in San Antonio early this morning after spending nearly two weeks recuperating in Germany.
The militant group known as the Islamic State of Iraq and Syria already controls the cities of Mosul and Tikrit, and has now taken towns in Diyalah province.
Elon Musk announced that Tesla would be opening up its patents for other companies to use. This open source policy could be a shrewd move for the company -- the more there is a culture around electric cars, the better chance they have of actually selling electric vehicles. Plus, President Obama makes his first visit to a Native American reservation as president. Also, with the U.S. market for fish being made up of 90 percent imports, its problematic that one third of that fish is caught illegally. More on the issues involved in combating illegal fishing.
Tesla Motors is going open source. Its CEO, Elon Musk, says the electric car company will no longer enforce its patents, in effect allowing competitors not only to peek at the technology Tesla has pioneered, but to copy it.
“Yesterday, there was a wall of Tesla patents in the lobby of our Palo Alto headquarters,” Musk said in a statement. “That is no longer the case. They have been removed in the spirit of the open source movement for the advancement of electric vehicle technology.”
“It is important to understand that, in many ways, patents are a tradeoff,” says R. Polk Wagner, a professor of law at the University of Pennsylvania. “Just because you have patents doesn’t mean you get anything out of them, necessarily.”
Sure, they can be valuable, but getting them and enforcing them is expensive.
According to Andrea James, an analyst with Dougherty & Co., the reason Tesla is doing this is “to accelerate electric vehicle adoption and innovation.”
“Tesla is really far ahead, and I think they just want to grow the overall market,” she says.
To succeed, Tesla needs more Americans to feel comfortable driving and buying electric cars. If more companies were to make them, that would help.
“It’s not a charity move,” says Michelle Krebs, a senior analyst with AutoTrader.com. “It’s a very smart business move.”
Competitors could use the network of charging stations Tesla is installing, or they could buy Tesla batteries.
Other car companies have charted a similar course in the past. Volvo decided not to enforce its patent for the three-point safety belt. GM shared the technology behind its catalytic converter.
Tesla says the move is in good faith. The company will still apply for patents, and if necessary, Musk says the carmaker won’t be afraid to fight back.
President Barack Obama's visit to the Standing Rock Sioux Tribe in North Dakota Friday will let him get a first-hand look at the challenges facing Native Americans. And there are many.
The Census Bureau says 27 percent of Native Americans are poor. Helen Oliff of National Relief Charities says on the reservations her organization serves, the poverty rate is actually higher, which exacerbates another problem: many Native Americans have little access to fresh, healthy food.
“You have a lot of convenience stores on the reservations," Oliff explains. "Many people are 30 to 60 miles away from the nearest regular grocery store.”
That leads many people to eat the pre-packed foods the convenience stores sell.
Unemployment is also problematic, partly because it's hard to reach jobs from remote reservations.
“When our reservation area was created, back in the day, it really put us in a box, literally," says Scott Davis, a Lakota Sioux and head of the North Dakota Indian Affairs Commission.
Davis says the Obama administration has given tribes more autonomy, and President Obama has included the Choctaw Nation in his Promise Zone program, which helps impoverished communities access federal resources.
