Carbon nanotechnology - stronger than Kevlar, light as a tee-shirt, and cheap all over

Most flexible polymers are inherently flimsy. When you look at their micro-structures it's easy to see why: They look like piles of entangled spaghetti strands. This leads to weak performance, says Northeastern University mechanical engineering professor Marilyn Minus, who is taking advantage of another scientific revolution to change this behavior: carbon nanotechnology.

Listening to cells: Scientists probe human cells with high-frequency sound

Researchers from the University of Bordeaux in France deployed high-frequency sound waves to test the stiffness and viscosity of the nuclei of individual human cells. The scientists predict that the probe could eventually help answer questions such as how cells adhere to medical implants and why healthy cells turn cancerous.

Scientists use Amazon Cloud to view molecular machinery in remarkable detail

Salk researchers share a how-to secret for biologists: code for Amazon Cloud that significantly reduces the time necessary to process data-intensive microscopic images. The method promises to speed research into the underlying causes of disease by making single-molecule microscopy of practical use for more laboratories.

Routes towards defect-free graphene

A new way of growing graphene without the defects that weaken it and prevent electrons from flowing freely within it could open the way to large-scale manufacturing of graphene-based devices with applications in fields such as electronics, energy, and healthcare.

Quantum dots deliver vitamin D to tumors for possible inflammatory breast cancer treatment

This new preliminary work shows the dots can be used to rapidly move high concentrations of calcitriol to targeted tumor sites where cancer cells accumulate, and also through the lymph system where the cancer spreads. With this approach, the calcitriol can fight on multiple fronts and the targeted location can be visualized with an imaging system tracking the quantum dots.
