In January, our news assistant Max Nesterak made a resolution to quit smoking. We decided to pitch in and help. Shankar gave Max three things to do based on social science research: write a public service announcement, get a support network, and put money budgeted for cigarettes into a savings account. It's been more than six months since you've heard from Max, so this week, we're checking in with him to see how he's doing.

Updated 1:40 a.m. ET with Juno orbit maneuver

After a nearly five-year journey, NASA's solar-powered Juno spacecraft achieved orbit around Jupiter on Monday night. Juno navigated a tricky maneuver — including slowing by around 1,212 mph — to insert itself into orbit in what NASA calls "the king of our solar system."

At 11:18 p.m. ET, Juno transmitted a radio signal to Earth that meant its main engine had switched on. It stayed on for 35 minutes, placing Juno into exactly the orbit that mission managers had planned for.

Robert Sauchelli doesn't have a solar panel, but he's all for the idea — before he retired, he devoted 21 years to energy efficiency work at the Environmental Protection Agency. To show his support, Sauchelli has been paying an extra 7.4 cents per kilowatt-hour to a clean power company, called Green Mountain Energy, through his energy supplier in Brooklyn, Con Edison.

Episiotomy, a once-routine surgical incision made in a woman's vaginal opening during childbirth to speed the baby's passage, has been officially discouraged for at least a decade by the leading association of obstetrician-gynecologists in the United States.

Nonetheless, despite evidence that the procedure is only rarely necessary, and in some cases leads to serious pain and injuries to the mother, it is still being performed at much higher than recommended rates by certain doctors and in certain hospitals.

At Edgewood Summit retirement community in Charleston, W.Va., 93-year-old Mary Mullens is waxing eloquent about her geriatrician, Dr. Todd Goldberg.

"He's sure got a lot to do," she says, "and does it so well."

West Virginia has the third oldest population in the nation, right behind Maine and Florida. But Goldberg is one of only 36 geriatricians in the state.

Cancer is personal for Vice President Joe Biden. It's been a little more than a year since his son Beau died at age 46. The cause was brain cancer.

"It's personal for me. But it's also personal for nearly every American, and millions of people around the world," Biden wrote on Medium in January. "We all know someone who has had cancer, or is fighting to beat it."

In space, there are no road maps. So if you happen to be heading to Jupiter, you'd better bring your own navigation tools.

One really useful tool is an instrument called a star tracker, essentially a camera with a built-in star catalog. It looks at a patch of sky, picks out stars it knows, and uses their coordinates to tell the spacecraft which way it's pointing.

As Chinese, Iranian and Indonesian As Apple Pie

Jul 3, 2016

The fireworks are stacked high, the beer is on ice, and lumps of charcoal glow hot under the grill in anticipation of hot dogs and hamburgers. Fourth of July is a holiday celebrated through food. There's potato salad, popsicles, watermelon slices — and, of course, apple pie.

After a five-year journey through the solar system, NASA's $1.1 billion Juno mission is set to begin its orbit around Jupiter on Monday. But for the probe to be captured by the giant planet's gravity and go into the desired orbit, Juno's main engine has to fire for 35 minutes.
