Stop us if you've heard this one: A spacecraft flies out of the solar system ...
Yes, the planetary probe Voyager 1, launched in the era of Jimmy Carter and bell-bottoms, has finally left the room, so to speak, years after completing its primary mission: a "grand tour" of the gas giants Jupiter and Saturn (twin Voyager 2 also visited Uranus and Neptune).
And years after we first started talking about its departure.

While most of us were distracted waiting for a gold iPhone — gold! — the billionaire industrialist Koch brothers quietly made a deal to acquire an electronics company for $7.2 billion. The company they bought? Molex.
In the past couple of weeks, several major companies — Samsung, Sony, Qualcomm — have announced they will release smart watches this fall. As the name suggests, the gadgets do more than keep time.
The latest spate of computerized watches promise to do everything from working as a phone to taking photos and fielding emails. Smart watches have actually been around for a long time, but they've never really taken off as a product.

The image on the left is a piece of lung tissue that contains a tumor viewed under normal white light. The right image shows the same piece of tissue after Tumor Paint has been applied. Here it's viewed under infrared light. Areas that are more red and yellow show a concentration of the paint, which means they are more likely to be cancerous.
Perhaps one of the most uncomfortable things a doctor has to tell patients is that their medical problems are iatrogenic. What that means is they were caused by a doctor in the course of the treatment.
Sometime these iatrogenic injuries are accidental. But sometimes, because of the limits of medical technology, they can be inevitable. Now, a medical researcher in Seattle thinks he has a way to eliminate some of the inevitable ones.

North Korea appears to be in the process of restarting a nuclear reactor used to produce weapons-grade plutonium, five years after shutting the facility down as part of international disarmament efforts.
New satellite imagery appears to reveal that the 5-megawatt reactor at Yongbyon, which experts believe can produce enough plutonium for one to two bombs a year, shows signs of being operational.
You can literally see rockets when you drive into Huntsville, Ala., also known as the "Rocket City." NASA's Marshall Space Flight Center is here, along with scores of aerospace and defense contractors. The city also has one of the largest fully digital school districts: 24,000 Huntsville City Schools students use laptops or tablets instead of textbooks.
All of this partly explains the new cybersecurity class at Grissom High School. Huntsville City Schools and U.S. Army Cyber Command are developing the curriculum, which will eventually begin in middle school.
I noticed in The Guardian that there's a book coming out this week listing the 20 biggest challenges for modern science. I'd like to go over 10 of them today, perhaps coming back to the other 10 next week.
