An aluminum alloy developed in the 1940s has long held promise for use in automobile manufacturing, except for one key obstacle. Although it’s nearly as strong as steel and just one-third the weight, it is almost impossible to weld together using the technique commonly used to assemble body panels or engine parts. That’s because when

Research from North Carolina State University has demonstrated a new technique that converts carbon fibers and nanotubes into diamond fibers at ambient temperature and pressure in air using a pulsed laser method. The conversion method involves melting the carbon using nanosecond laser pulses and then quenching, or rapidly cooling, the material. These diamond fibers could

Immunotherapy’s promise in the fight against cancer drew international attention after two scientists won a Nobel Prize this year for unleashing the ability of the immune system to eliminate tumor cells. But their approach, which keeps cancer cells from shutting off the immune system’s powerful T-cells before they can fight tumors, is just one way

One day, hospital patients might be able to ingest tiny robots that deliver drugs directly to diseased tissue, thanks to research being carried out at EPFL and ETH Zurich. A group of scientists led by Selman Sakar at EPFL and Bradley Nelson at ETH Zurich drew inspiration from bacteria to design smart, highly flexible biocompatible

A recent study, affiliated with South Korea’s Ulsan National Institute of Science and Technology (UNIST) has introduced a novel targeted drug delivery system in the fight against cancer. A team of researchers, affiliated with UNIST has recently introduced a novel targeted drug delivery system that can improve the pharmacological and therapeutic properties of conventional cancer

University of Alberta chemists have taken a critical step toward creating a new generation of silicon-based lithium ion batteries with 10 times the charge capacity of current cells. “We wanted to test how different sizes of silicon nanoparticles could affect fracturing inside these batteries,” said Jillian Buriak, a U of A chemist and Canada Research

There are many times when our cells need to move. Mobile cells guide our body’s formation (embryonic development). Immune cells roam to capture unwanted intruders. And healing cells (fibroblasts) migrate to mend wounds. But not all movement is desirable: Tumors are most dangerous when cancer cells gain the ability to travel throughout the body (metastasis).

Researchers at The University of Manchester’s National Graphene Institute in the UK have succeeded in making artificial channels just one atom in size for the first time. The new capillaries, which are very much like natural protein channels such as aquaporins, are small enough to block the flow of smallest ions like Na+ and Cl-

Imagine if you could look at a small amount of an unidentified chemical element – less than 100 atoms in size – and know what type of material the element would become in large quantities before you actually saw the larger accumulation. That thought has long animated the work of Julius Jellinek, senior scientist emeritus

The transition from electronic integrated circuits to faster, more energy-efficient and interference-free optical circuits is one of the most important goals in the development of photon technologies. Photonic integrated circuits (PICs) are already used today for transmitting and processing signals in optical networks and communication systems, including, for example, I/O multiplexers of optical signals and
