Takes a licking and keeps on storing

Researchers at Washington University in St. Louis made an energy storage device that can withstand a hammer striking it more than 40 times. The shatterproof supercapacitor is also nonflammable, unlike lithium-ion batteries. The new work is the cover story of the April 23 issue of the journal Sustainable Energy and Fuels.

Astronauts might soon grow SPACE tomatoes

Tiny tomato plants developed at the University of California, Riverside, could one day feed astronauts on the International Space Station. The plants have minimal leaves and stems but still produce a normal amount of fruit, making them a potentially productive crop for cultivation anywhere with limited soil and natural resources.

A first in medical robotics: Autonomous navigation inside the body

Bioengineers at Boston Children's Hospital report the first demonstration of a robot able to navigate autonomously inside the body. In an animal model of cardiac valve repair, the team programmed a robotic catheter to find its way along the walls of a beating, blood-filled heart to a leaky valve—without a surgeon's guidance. They report their work today in Science Robotics.

Researchers use a novel approach to identify a transport protein in mycobacteria

A team headed by Dr. Claudia Jessen-Trefzer of the University of Freiburg's Institute for Pharmaceuticals Sciences has identified a transport protein in mycobacteria that is responsible for the uptake of the nutrient L-arabinofuranose. The lead authors of the study, Miaomiao Li of the Institute for Pharmaceuticals Sciences, Christoph Müller of the Institute for Biochemistry and Klemens Fröhlich of the Institute of Molecular Medicine and Cell Research at the University of Freiburg, used a novel approach that could simplify the identification of transport proteins in mycobacteria in the future. This class of proteins could play a key role in the development of new types of medications to tackle mycobacteria and treat diseases like tuberculosis in humans. The researchers' study is published in the journal Cell Chemical Biology.

No assembly required: Researchers automate microrobotic designs

Assembling a microrobot used to require a pair of needle-nosed tweezers, a microscope, steady hands and at least eight hours. But now University of Toronto Engineering researchers have developed a method that requires only a 3-D printer and 20 minutes.

New AAP PROS study assesses influenza vaccine hesitancy among caregivers of children

Even caregivers whose children receive the first dose of influenza vaccine may be vaccine hesitant and have inaccurate beliefs regarding influenza vaccine and disease, according to a new American Academy of Pediatrics (AAP) Pediatric Research in Office Settings (PROS) study that was a collaboration between investigators at Children's Hospital of Philadelphia (CHOP), Columbia University Irving Medical Center, and the AAP. Findings from the study will be presented during the Pediatric Academic Societies (PAS) 2019 Meeting, taking place on April 24—May 1 in Baltimore.

Tiny robots powered by magnetic fields could help drug-delivery nanoparticles reach their targets

MIT engineers have designed tiny robots that can help drug-delivery nanoparticles push their way out of the bloodstream and into a tumor or another disease site. Like crafts in "Fantastic Voyage"—a 1960s science fiction film in which a submarine crew shrinks in size and roams a body to repair damaged cells—the robots swim through the bloodstream, creating a current that drags nanoparticles along with them.

Placental function linked to brain injuries associated with autism

Allopregnanolone (ALLO), a hormone made by the placenta late in pregnancy, is such a potent neurosteroid that disrupting its steady supply to the developing fetus can leave it vulnerable to brain injuries associated with autism spectrum disorder (ASD), according to Children's research presented during the Pediatric Academic Societies 2019 Annual Meeting.
