Water purification without Chlorine. I think the recent situation in Detroit shows it may not work. Ozone may be a good alternative. I think a bigger issue is fluorination, which can affect bones over time.
Thin solar cells could be placed anywhere and integrated into materials and devices.
Solar cell has been developed to split water into oxygen and hydrogen in the day and recombine at night to produce and store energy.
A Q&A about the recent use of immune cells to treat cancer
Scientists discover electric signals jump from silicon to rare earths, which would allow integration of optical fiber and conducting wires
New techniques to create higher temperature superconductors
A summary of advances in optical metamaterials
Parallel Computing with bio/nanotech
A new method to separate hydrogen isotopes would help with nuclear fusion
A method to create carbon backbones without metal catalysts
Another light activated catalyst for breaking water into hydrogen and oxygen
Several recent developments in nanotech
First uterus transplant. Growing a uterus from stem cells and keeping it alive outside a human body or in an animal could end abortion issues by allowing an unexpected or unaffordable baby to develop and be adopted.
By recording brain activity and transmitting it to other subjects scientists improved learning
Improved method to sort cells
Needle free vaccination for Polio
New medical cardiac pump with remote monitoring
A return to the true collaborative tradition of science
Disney has developed a system to automatically recreate realistic motion of characters in virtual environments. I believe this could be useful for real life robots too.
Another skyscraper that fits the current spiral trend
Steps in the growth of metal clusters. An unmentioned application could be development of new alloys and metallurgical techniques.
New test for anemia
