Until now, optically active quantum dots have not been observed in materials consisting of a single layer of atom, also known as 2D materials. Rochester researchers have shown how the 2D material tungsten diselenide can be fashioned into an atomically thin semiconductor that serves as a platform for solid-state quantum dots.

Researchers in the Institute of Optics have shown that a microplasma created by focusing intense laser pulses in air emits not only visible light, but also electromagnetic pulses at terahertz frequencies that can be used to detect complex molecules, such as explosives and drugs.

Sir Sidney Poitier became a cultural icon in the 1950s as the first black actor to break racial barriers in film. But as art and art history professor Sharon Willis argues in her new book, his image on screen creates a false sense of equality that continues to appear in the popular media and remains damaging to race relations today.

Therapeutic anti-bacterial agents intended to reduce dental plaque and prevent tooth decay are often removed by saliva and the act of swallowing before they can take effect. But a team of researchers has developed a way to keep the drugs from being washed away.

Speaking in public is the top fear for many people. Now, students and faculty from the Human-Computer Interaction Group have developed an intelligent user interface for “smart glasses” that gives real-time feedback to the speaker on volume modulation and speaking rate, and have made the tool freely available for downloading.

A University team found a way to make chemotherapy more effective by exposing cancer cells to a molecule that inhibits NMD (nonsense-mediated mRNA decay) prior to treatment with doxorubicin, a drug used to treat leukemia, breast, bone, lung and other cancers.

Rochester researchers and their collaborators have developed a way to transfer 2.05 bits per photon by using “twisted light.” The new approach doubles the 1 bit per photon that is possible with current systems that rely on light polarization and could help increase the efficiency of quantum cryptography systems.

In his new book, professor of history Stewart Weaver chronicles journeys of discovery from the pre-historic trek of humans across the land bridge over the Bering Strait some 12,000 years ago to the mid-20th century deep sea voyages of Jacques-Yves Cousteau.

A recently discovered dim star likely passed some 70,000 years ago through our solar system’s distant cloud of comets known as the Oort Cloud. No other star is known to have ever approached our solar system this closely.

Although most materials slightly expand when heated, there is a new class of rubber-like material that not only self-stretches upon cooling; it reverts back to its original shape when heated, all without physical manipulation.
