As hands come in left and right versions that are mirror images of each other, so do the amino acids and sugars within us. But unlike hands, only the left-oriented amino acids and the right-oriented sugars ever make into life as we know it.

Scientists are aware that these agricultural wastes have significantly high silica content in a molecular state, similar to hydrocarbons. Armed with that knowledge, researchers have discovered that these agricultural waste products can be economically transformed into silicon carbide consisting of nanostructures and nanorods in various polytypes.

Theoretically, iron pyrite could do the job, but when it works at all, the conversion efficiency remains frustratingly low. Now, a research team explains why that is, in a discovery that suggests how improvements in this promising material could lead to inexpensive yet efficient solar cells.

No comprehensive study has yet been carried out to characterize the photoexcited lattice dynamics of an opaque thin film on a semi-infinite transparent substrate. As a result, ultrafast X-ray diffraction data for such samples can be challenging to interpret. Now a new study builds a model to help interpret such data.

MIT chemists have developed new nanoparticles that can simultaneously perform magnetic resonance imaging (MRI) and fluorescent imaging in living animals. Such particles could help scientists to track specific molecules produced in the body, monitor a tumor's environment, or determine whether drugs have successfully reached their targets.
