Where will California"s record snowpack melt into floods? It"s complicated
After months of heavy rain across California and record snow in the southern Sierra Nevada, state officials warn that melting snow could turn into flooding as the state's skies turn sunnier this spring and summer......»»
Photoacoustic remote sensing microscopy for lipid imaging
Photoacoustic imaging is a cutting-edge technology that uses light and sound to create images of the inside of the body. When a pulsed laser illuminates the surface of biological tissue, part of the photon energy is absorbed by the tissue to generate.....»»

Cutting cable bacteria with a laser puts an end to a bacterial party
The party-poopers cutting the cable bacteria are researchers from the Center for Electromicrobiology (CEM) at Aarhus University. The center's work focuses on unraveling the mysteries of how cable bacteria work......»»
Intense lasers magnetize solids within attoseconds
Intense laser light can induce magnetism in solids on the attosecond scale—the fastest magnetic response to date. That is the finding reached by theoreticians at the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany,.....»»
Researchers correlate Arctic warming to extreme winter weather in midlatitude and extrapolate its future
Pictures of melting glaciers and stranded polar bears on shrinking sea ice in the Arctic are perhaps the most striking images that have been used to highlights the effects of global warming. However, they do not convey the full extent of the conseque.....»»
Hot electron electrochemistry with ultrafast laser pulses
Laser-induced electrochemical deposition of metals on metals relies possibly on thermal and defect generation effects. When semiconductor substrates are chosen, locally photogenerated electrons can reduce metal ions resulting in metallic surface stru.....»»
