A new type of soft robot gets its power from the skin it’s in.
Robotic skin that bends, stretches and contracts can wrap around inanimate objects like stuffed animals, foam tubes or balloons to create flexible, lightweight robots. Removable, reusable sheets of this artificial skin, described online September 19 in Science Robotics, could also be used to build grippers or wearable devices...
Cells past their prime may have a role in dementia. Culling these cells protected the brains of mice that were otherwise destined for brain decline, a new study finds.
Senescent cells, which accumulate with age, are still alive but in a state of suspended animation — they stop doing their jobs and they stop dividing. Getting rid of these cells in the body extends the life spans of mice...
A daily dose of aspirin? Not a good idea if you’re a healthy elderly adult.
A trio of papers based on a large-scale clinical trial finds that the drug doesn’t help to stave off heart attacks, strokes, dementia or physical disability. In fact, those in their golden years who took a low dose of aspirin daily were more likely to suffer serious internal bleeding than those who took a placebo...
Diana Parno’s head swam when she first stepped inside the enormous, metallic vessel of the experiment KATRIN. Within the house-sized, oblong structure, everything was symmetrical, clean and blindingly shiny, says Parno, a physicist at Carnegie Mellon University in Pittsburgh. “It was incredibly disorienting.”
Now, electrons — thankfully immune to bouts of dizziness — traverse the inside...

Fighting fake news09/19/2018 - 07:15 Science & Society, Health, Particle Physics
Computer programmers are building deception-detecting algorithms to fight the onslaught of fake news, Maria Temming reported in “People are bad at spotting fake news. Can computer programs do better?"(SN: 8/4/18, p. 22).
Reader Lou Floyd found the story compelling and troubling. “It points [to] a major problem facing us all today that affects the very foundation of...
When I think of an experiment, I think of some flasks, a pipette, maybe an incubator. But to a particle physicist, an experiment can be a machine bigger than a house, designed to study subatomic particles.09/19/2018 - 07:00 Science & Society, Particle Physics
There’s a certain charm to the fact that such vast equipment has to be constructed to study the smallest known bits of matter. The tunnel of the Large Hadron Collider has a...
News in Brief
The next exoplanet hunt is officially on. NASA’s Transiting Exoplanet Survey Satellite (TESS), which launched in April (SN: 5/12/18, p. 7), has taken its first wide-sky science image and has confirmed its first exoplanet.
The “first light” image (the moniker for a new telescope’s first useful image), taken August 7 with all four of the telescope’s cameras and released September 17, shows...
An enormous future particle detector is now within closer reach. The first data from a prototype experiment hint that scientists may have what it takes to build the planned neutrino detector.
Known as the Deep Underground Neutrino Experiment, or DUNE, the experiment will use 70,000 metric tons of liquefied argon to study the secrets of these neutrinos — bizarre, nearly massless particles...
For Daily Use
Identifying faulty drugs or diagnosing kidney problems could one day be as simple as playing an instrument and analyzing the sound.
An inexpensive, handheld tool inspired by an ancient African instrument called an mbira, or thumb piano, can distinguish between liquids of different densities, researchers report online September 12 in ACS Omega. That could help pharmacists and consumers...

The Revolutionary Genius of PlantsStefano MancusoAtria Books, $30
More than 200 years ago, French botanist René Desfontaines instructed a student to monitor the behavior of Mimosa pudica plants as he drove them around Paris in a carriage. Mimosa pudica quickly closes its leaves when touched — presumably as a defense mechanism. Desfontaines was interested in the plants’ response to...
