Tiny 'on-chip detectors' count individual photons
A team of researchers has integrated tiny detectors capable of counting individual photons on computer chips. These detectors, called "single-photon avalanche diodes (SPAD)," act like mini Geiger counters, producing a "tick" each time a photon is detected.

Green sludge can protect groundwater from radioactive contamination
Radioactive waste decaying down at the dump needs millions of years to stabilize. The element Neptunium, a waste product from uranium reactors, could pose an especially serious health risk should it ever seep its way into groundwater - even 5 million years after its deposition. Now, researchers at the University of Copenhagen have shown the hazardous waste can be captured and contained.

Modified mRNA is the key to novel anti-cancer therapy
Modifications of ribonucleic acid mRNA introduced by scientists from the Faculty of Physics, University of Warsaw in collaboration with the Louisiana State University are blazing a trail for safer and more effective gene drugs. Clinical trials of the first new-generation anti-cancer vaccine, developed in Germany with the aid of the Polish invention, will begin already later this year.

Study finds more efficient means of creating, arranging carbon nanofibers
Carbon nanofibers hold promise for technologies ranging from medical imaging devices to precise scientific measurement tools, but the time and expense associated with uniformly creating nanofibers of the correct size has been an obstacle - until now. A new study from North Carolina State University demonstrates an improved method for creating carbon nanofibers of specific sizes, as well as explaining the science behind the method.

Scientists control light scattering in graphene
Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have learned to control the quantum pathways determining how light scatters in graphene. Controlled scattering provides a new tool for the study of this unique material and may point to practical applications for controlling light and electronic states in graphene nanodevices.
