In Orbit or on Earth, Implantable Device Will Be Commanded to Release Therapeutic Drugs Remotely

nDS-hi.jpg

Scientists will receive about $1.25 million from the Center for the Advancement of Science in Space to develop an implantable device that delivers therapeutic drugs at a rate guided by remote control. The device's effectiveness will be tested aboard the International Space Station and on Earth's surface.

Nanoparticle-Based Invention Moves New Drugs Closer to Clinical Testing

Penn State College of Medicine researchers have developed a nanoparticle to deliver a melanoma-fighting drug directly to the cancer. Delivering cancer drugs directly to tumors is difficult. Scientists are working on new approaches to overcome the natural limitations of drugs, including loading them into nanoparticles.

See-Through, One-Atom-Thick, Carbon Electrodes Powerful Tool to Study Brain Disorders

LittNatCommsarrayOct14pic.jpg

A graphene, one-atom-thick microelectrode now solves a major problem for investigators looking at brain circuitry. Pinning down the details of how individual neural circuits operate in epilepsy and other brain disorders requires real-time observation of their locations, firing patterns, and other factors.

Goldilocks Principle Wrong for Particle Assembly: Too Hot & Too Cold Is Just Right

LangNatureMaterials2014.jpg

Microscopic particles that bind under low temperatures will melt as temperatures rise to moderate levels, but re-connect under hotter conditions, a team of New York University scientists has found. Their discovery points to new ways to create “smart materials,” cutting-edge materials that adapt to their environment by taking new forms, and to sharpen the detail of 3D printing.

Researchers Develop World’s Thinnest Electric Generator

Hone-WangGTPiezoelectricMoS2Naturepaperimage.png

Researchers from Columbia Engineering and the Georgia Institute of Technology report today that they have made the first experimental observation of piezoelectricity and the piezotronic effect in an atomically thin material, molybdenum disulfide (MoS2), resulting in a unique electric generator and mechanosensation devices that are optically transparent, extremely light, and very bendable and stretchable.

Beyond LEDs: Brighter, New Energy -Saving Flat Panel Lights Based on Carbon Nanotubes

planarlight-1_1.jpg

Scientists from Tohoku University in Japan have developed a new type of energy-efficient flat light source based on carbon nanotubes with very low power consumption of around 0.1 Watt for every hour’s operation--about a hundred times lower than that of an LED.

Plasmonic Paper

AVS-plasmonic-Singamaneni.jpg

Using a common laboratory filter paper decorated with gold nanoparticles, researchers have created a unique platform, known as “plasmonic paper,” for detecting and characterizing even trace amounts of chemicals and biologically important molecules—from explosives, chemical warfare agents and environmental pollutants to disease markers. The work will be described at the AVS 61th International Symposium and Exhibition.

'Stealth' Nanoparticles Could Improve Cancer Vaccines


624055image1.jpg

Cancer vaccines have recently emerged as a promising approach for killing tumor cells before they spread. But so far, most clinical candidates haven't worked that well. Now, scientists have developed a new way to deliver vaccines that successfully stifled tumor growth when tested in laboratory mice. And the key, they report in the journal ACS Nano, is in the vaccine's unique stealthy nanoparticles.

Taking Thin Films to the Extreme

APL-Kats-ThinFilms.jpg

Applying a well-known optical phenomenon called thin-film interference, a group of researchers at Harvard University has demonstrated the ability to "paint" ultra-thin coatings onto a rough surface -- work that holds promise for making future, flexible electronic devices, creating advanced solar cells and detailing the sides of next-gen rocket ships and spacecraft with extremely lightweight decorative logos (Applied Physics Letters).

How Things Coil

Columbia Engineering and MIT researchers have combined computer simulations designed for Hollywood with precision model experiments to examine the mechanics of coiling. Their study, which bridges engineering mechanics and computer graphics, impacts a variety of engineering applications, from the fabrication of nanotube serpentines to the laying of submarine cables and pipelines (published 9/29 PNAS Early Online edition).
