3D printing a brain to understand its folds

Now, by 3D-printing a fake gel brain and watching it grow scientists have discovered how the human brain develops its folds.

New frontiers in 3D printing

Three dimensional printing is revolutionizing the production of new devices and structures, including soft robots, flexible electronics and engineered tissue replacements, but advances have been challenged by the inherent complexity of integrating multiple materials.

Hands on: crafting ultrathin color coatings

A technique that coats a metallic object with an extremely thin layer of semiconductor, just a few nanometers thick. Although the semiconductor is a steely gray color, the object ends up shining in vibrant hues.

A self-organizing thousand-robot swarm

The first thousand-robot flash mob has assembled at Harvard University.

Infrared: A new renewable energy source?

Physicists envision a device that would harvest energy from Earth's infrared emissions into outer space.

Organic mega flow battery promises breakthrough for renewable energy

A team of scientists and engineers has demonstrated a new type of battery that could fundamentally transform the way electricity is stored on the grid, making power from renewable energy sources such as wind and solar far more economical and reliable.

New coating turns ordinary glass into super-slippery glass

A new transparent, bioinspired coating makes ordinary glass tough, self-cleaning and incredibly slippery according to Researchers

Printing microbatteries the size of a grain of sand

3D printing can now be used to print lithium-ion microbatteries the size of a grain of sand.

New fuel cell keeps going after the hydrogen runs out

Materials scientists at Harvard have demonstrated a solid-oxide fuel cell (SOFC) that converts hydrogen into electricity but can also store electrochemical energy like a battery. This fuel cell can continue to produce power for a short time after its fuel has run out.

Microbial fuel cell-based charger for mobile phones

A project to use dirt-powered batteries to charge cell phones in Africa has won a $100,000 grant from The Bill & Melinda Gates Foundation.
