Watch Dwarf Planet Ceres As It Spins
NASA’s Dawn spacecraft is about to get up, close, and personal with Ceres, a dwarf planet that’s been lurking in the asteroid belt. As it approaches, Dawn has been snapping some amazing images of the rock, and it just took some of its highest-resolution photographs yet.
Not content with releasing them as still images, NASA turned them into a movie, a spinning recreation of what most of Ceres’ surface looks like. The images were taken when Dawn was 90,000 miles away; they have a resolution of 8.5 miles per pixel, making them the sharpest photos yet of the dwarf planet between Mars and…

How Stressed Are You? [Quiz]
Afraid of needles? Pick up a pencil. In addition to drawing blood to check for stress markers, scientists craft quizzes to reveal whether you’re feeling harmful stress. This one was adapted from the Perceived Stress Scale by Sheldon Cohen, a psychoneuroimmunologist at Carnegie Mellon University.
This quiz was originally published as part of the "Science Of Stress" feature in the March 2015 issue of Popular Science. To find out more about stress--including how to beat it--check out the rest of the article.…

9 Strategies For Battling Stress
A little stress can be a good thing, but it’s important to keep it under control. These strategies will help you retain your Zen.
1. Bounce Back
Some people are naturally resilient, but it’s also a learned skill. Stress inoculation gradually exposes people to stressful situations so they develop calmer reactions. Elizabeth Stanley, a security studies expert from Georgetown University, uses this training to help soldiers prepare for high-stress missions. And a 2014 study from Islamic Azad University in Iran suggests the technique can help civilians too.
2. Say Om

Not All Stress Monitors Are Created Equal [Review]
There are gadgets to measure everything, from what we eat to how many steps we take—and now, a new breed of devices claims to monitor stress. I tested three over the course of a week that included pulse-quickening deadlines, public speaking, and both a computer and smartphone malfunction, as well as more soothing activities such as curling up on the couch on a rainy Saturday and getting a mid-week massage (hey, it was for work). My conclusion? Not all stress monitors are created equal.

Why Are Some People Better At Dealing With Stress?
Some people recover from trauma and tragedy more quickly than others—for example, around a quarter of war veterans develop post-traumatic stress disorder, while many of their peers who saw similar violence do not. Researchers are still trying to unravel why, but the answer may be partly embedded in our cells. Neuroscientists at the Icahn School of Medicine at Mount Sinai have shown that mice especially resilient to stress have increased levels of a protein called beta-catenin, which acts in a reward center called the nucleus accumbens. They have confirmed their findings in postmortem human…

In Space, No One Can Hear You Stress
The daily grind can be stressful enough, but what happens when you move it to low Earth orbit, 268 miles above the planet’s surface? To find out, Popular Science caught up with veteran NASA astronaut and space medicine specialist Michael Barratt, whose resume includes stints with the Mir Program and the International Space Station. Occupational stress, it turns out, is pretty similar out in space. That is, so long as you don’t think too hard about the finicky robotic arms, space walk mishaps, or the station’s massive stock of propellants and explosives.

When There's Nothing Left To Do But Crack A Cancer Joke
Comedian Tig Notaro had a famously stressful year in 2012. Within months, she got pneumonia, Clostridium difficile (an intestinal infection spurred by antibiotic use), went through a breakup, her mom died unexpectedly, and she was diagnosed with breast cancer. It doesn’t exactly sound like comedy gold. But even before the shock had worn off, Notaro was airing her woes on a stage in Los Angeles. The now-legendary set killed. Popular Science recently caught up with Notaro to talk about finding the comedy in tragedy.

Staying Calm When Lives Are at Stake
Over the past year, some of the most harrowing international stories have come from West Africa, the epicenter of an unprecedented outbreak of Ebola. As both local and international medical experts have scrambled to stem the virus’ spread, they’ve also had to balance their own anxieties in an unusually stressful situation. Popular Science asked Alex Kumar, an infectious disease doctor who volunteered with the British Red Cross in Sierra Leone, how he handled the strain.
