Lasers etch a 'perfect' solar energy absorber

The University of Rochester research lab that recently used lasers to create unsinkable metallic structures has now demonstrated how the same technology could be used to create highly efficient solar power generators.

Turning up the heat on antibacterial-resistant diseases

Photothermal therapy (PTT) is a proposed treatment for diseases like antibacterial-resistant infections and cancer, but despite over a decade of research, scientists have been unable to find a safe and effective chemical ...

Stellar heavy metals can trace history of galaxies

Astronomers have cataloged signs of nine heavy metals in the infrared light from supergiant and giant stars. New observations based on this catalog will help researchers to understand how events like binary neutron star mergers ...

Image: Hubble eyes an emitting galaxy

For this image, the NASA/ESA Hubble Space Telescope turned its powerful eye toward an emission-line galaxy called NGC 3749.

Experimental physicists redefine ultrafast, coherent magnetism

Electronic properties of materials can be directly influenced via light absorption in under a femtosecond (10-15 seconds), which is regarded as the limit of the maximum achievable speed of electronic circuits. In contrast, ...

Chemists build a better cancer-killing drill

An international team of scientists is getting closer to perfecting molecule-sized motors that drill through the surface of cancer cells, killing them in an instant.

Bumps on peacock spider make dark spots super-dark

A team of researchers with members from Harvard University, the University of Bonn, the University of Denmark and Yale University has identified bumps on the abdomens of male peacock spiders that make their dark-colored patches ...
