4-D imaging with liquid crystal microlenses

Most images captured by a camera lens are flat and two dimensional. Increasingly, 3-D imaging technologies are providing the crucial context of depth for scientific and medical applications. 4-D imaging, which adds information ...

Making bismuth behave like a transition metal

A team of researchers at the Max Planck Institut für Kohlenforschung has found a way to get bismuth to behave like a transition metal. In their paper published in the journal Science, the group describes their method to ...

New material mimics strength, toughness of mother of pearl

In the summer, many people enjoy walks along the beach looking for seashells. Among the most prized are those that contain iridescent mother of pearl (also known as nacre) inside. But many beachcombers would be surprised ...

Researchers find access to new fluorescent materials

Fluorescence is a fascinating natural phenomenon. It is based on the fact that certain materials can absorb light of a certain wavelength and then emit light of a different wavelength. Fluorescent materials play an important ...

Scientists devise algorithm to engineer improved enzymes

Scientists have prototyped a new method for "rationally engineering" enzymes to deliver improved performance. They have devised an algorithm, which takes into account an enzyme's evolutionary history, to flag where mutations ...
