Good vibrations: Using light-heated water to deliv...

Researchers from the University of California, San Diego Skaggs School of Pharmacy and Pharmaceutical Sciences, in collaboration with materials scientists, engineers and neurobiologists, have discovered a new mechanism for using light to activate drug-delivering nanoparticles and other targeted therapeutic substances inside the body. This discovery represents a major innovation, said Adah Almutairi, PhD, associate professor...

Nano-paper filter removes viruses

Nanotechnology and Functional Materials, Uppsala University have developed a paper filter, which can remove virus particles with the efficiency matching that of the best industrial virus filters. The paper filter consists of 100 percent high purity cellulose nanofibers, directly derived from nature. The research was carried out in collaboration with virologists from the Swedish University of Agricultural Sciences/Swedish...

Radiation able to be securely stored in nontoxic m...

Researchers have discovered that microscopic “bubbles” developed at Kansas State University are safe and effective storage lockers for harmful isotopes that emit ionizing radiation for treating tumors. The findings can benefit patient health and advance radiation therapy used to treat cancer and other diseases, said John M. Tomich, a professor of biochemistry and molecular biophysics who is affiliated with the...

Self-assembling cages built from DNA

Move over, nanotechnologists, and make room for the biggest of the small. Scientists at the Harvard’s Wyss Institute have built a set of self-assembling DNA cages one-tenth as wide as a bacterium. The structures are some of the largest and most complex structures ever constructed solely from DNA, they report online in Science. Moreover, the scientists visualized them using a DNA-based super-resolution microscopy method...

Hair-like constructs offer drug screening platform

Scientists from A*STAR have successfully engineered cellular structures resembling hair follicles in the laboratory — a tool that can now be used to develop new therapies to promote or decrease hair growth (“Follicular dermal papilla structures by organization of epithelial and mesenchymal cells in interfacial polyelectrolyte complex fibers”). “The follicle-like structures of our model form the basis of a...

Qualcomm to Build Neuro-Inspired Chips

The world’s largest smartphone chipmaker, Qualcomm, says it is ready to start helping partners manufacture a radically different kind of a chip—one that mimics the neural structures and processing methods found in the brain. The approach is emerging as a way to enable machines to perform complex tasks while consuming far less power. IBM has been prototyping similar chips (see “IBM Scientists Show Blueprints for...
