‘Matrix’-like brain training to speed up physical therapy possible in the future

Neurological-brain

It’s no easy task to learn to walk again after a traumatic accident. One of the hardest things for motor-impaired patients is to generate the correct brain signals to help them recover efficiently.

Key To Early Cancer Diagnosis Discovered By Bioengineering Student

Key To Early Cancer Diagnosis Discovered By Bioengineering Student

Raj Krishnan, a PhD student in bioengineering at the University of California San Diego (UCSD)

Cancers that are detected early have the best chance of being cured but, until now, there were no methods of detecting cancer at its earliest stages.  Raj Krishnan, a PhD student in bioengineering at the University of California San Diego (UCSD), has created a technology for the early diagnosis of cancer, giving new hope and possibility to cures that have eluded cancer victims for years because their diagnoses were too late.

Nanonets Could Convert Sunlight Into Hydrogen

Nanonets Could Convert Sunlight Into Hydrogen

The top image shows a nanonet magnified 50,000 times. At bottom, a
flexible nanonet rolls up when poked by the tip of a scanning tunneling microscope.

One problem with solar cells is that they only produce electricity during the day. A promising way to use the sun’s energy more efficiently is to enlist it to split water into hydrogen gas that can be stored and then employed at any time, day or night. A cheap new nanostructured material could prove an efficient catalyst for performing this reaction. Called a nanonet because of its two-dimensional branching structure, the material is made up of a compound that has been demonstrated to enable the water-splitting reaction. Because of its high surface area, the nanonet enhances this reaction.

Carbon Nanotubes Used to Improve Fuel Cells

Carbon Nanotubes Used to Improve Fuel Cells

A group of scientists has created a new, improved fuel-cell electrode that is very lightweight and thin. Composed of a network of single-walled carbon nanotubes, the electrode functions nearly as well as conventional electrodes but renders the entire fuel cell much lighter. The research is an important step toward lightweight power supplies, which are becoming necessary as electronic devices get ever smaller and more streamlined.
