An international team of researchers has used nanoparticles to deliver a drug into specific compartments of nerve cells, dramatically increasing its ability to treat pain in mice and rats. The drug that the researchers encapsulated into nanoparticles is an FDA-approved drug used to prevent nausea and vomiting that had previously failed clinical trials as a pain medication.

Kara Fan, a 14-year-old eighth-grader from California, is America's new top young scientist. Her invention — a nano particle liquid bandage to replace antibiotics — beat out nine other finalists in the 3M Young Scientist Challenge, a national competition held every year in St. Paul, Minnesota.

MIT researchers have developed a device that removes carbon dioxide from air. The device is essentially a large battery that absorbs carbon dioxide from a gas stream passing over its electrodes as it is being charged up and then releases carbon dioxide as it is being discharged. The electrodes are coated with a compound that contains carbon nanotubes.

A team of researchers at the University of Michigan has built catalysts that guides chemical reactions toward the right version of chiral molecules. This discovery could lead to more efficient production of some medicines. The catalysts, which are assemblies of mineral nanoparticles made chiefly from zinc oxide, are at least 10 times better at selecting a particular version of a chiral molecule than earlier catalysts of this type.

A team of scientists at Argonne National Laboratory has developed a powerful technique for probing in three dimensions the crystalline structure of cathode materials at the nanoscale inside a battery. In particular, the technique probes what happens during the process of "intercalation" — the insertion of ions between the layers of a cathode when a battery generates electricity.

Scientists from Washington University School of Medicine in St. Louis and the University of South Florida Health Morsani College of Medicine, Tampa, Fla., have demonstrated that peptide-based nanoparticles can suppress pancreatic cancer growth without the toxic side effects and therapeutic resistance seen in drug trials. The nanoparticles deliver an RNA molecule that silences the chemical signal telling a gene to make mutated proteins that cause pancreatic cells to grow uncontrollably and resist existing cancer-killing drugs.

Physicists at the University of Oregon have developed a fast and sensitive bolometer that can measure light at and far above room temperature. A bolometer is a sensitive electrical instrument that measures the power of incident electromagnetic radiation. The new device, which consists of a trampoline-shaped piece of graphene suspended over a hole, offers an alternative to conventional electronic light detectors, such as those found in a smartphone's camera.

Physicists at MIT and elsewhere have, for the first time, discovered fractal-like patterns in a quantum material—a material that exhibits strange electronic or magnetic behavior, as a result of quantum, atomic-scale effects. A fractal is any geometric pattern that occurs again and again, at different sizes and scales, within the same object. The team made this discovery while measuring the material's magnetic domains at the nanoscale.

One of the 2019 Moore Inventor Fellows (who were announced on Oct. 15) is developing a camera to enable worldwide precision farming practices that would significantly reduce water, energy, fertilizer, and pesticide use while increasing yields. This camera takes advantage of a phenomenon called plasmonics—the use of nanoscale physical phenomena to trap certain frequencies of light.

Most attempts to turn textiles into wearable technology use stiff metallic fibers that alter the texture and physical behavior of the fabric. And coating methods that are successfully able to apply enough material to a textile substrate to make it highly conductive also tend to make the yarns and fabrics too brittle to withstand normal wear and tear. Now researchers at Drexel University have shown that they can create a highly conductive, durable yarn by coating standard cellulose-based yarns with a type of conductive two-dimensional material called MXene.
