Delayed time zero in photoemission

Until now, it has been assumed that during photoemission the electron start moving out of the atom immediately after the impact of the photon. This point in time can be detected and has so far been considered as coincident with the arrival time of the light pulse, i.e. with 'time zero' in the interaction of light with matter. Using their ultra-short time measurement technology, physicists have now tested this assumption.

Researchers develop living, breathing human lung-on-a-chip

Researchers from the Wyss Institute for Biologically Inspired Engineering at Harvard University, Harvard Medical School and Children's Hospital Boston have created a device that mimics a living, breathing human lung on a microchip. The device, about the size of a rubber eraser, acts much like a lung in a human body and is made using human lung and blood vessel cells.

Gene therapy a step closer to mass production

EUREKA project E! 3371 Gene Transfer Agents has made great advances in the development of novel non-viral carriers able to introduce genetic material into the target cells. These new agents, derivatives of cationic amphiphilic 1,4-dihydropyridine (1,4-DHP), avoid the problems of the recipient's immune system reacting against a viral carrier.

Scientists show that the first step already affects the efficiency of hydrogen generation

In trying to copy the photosynthesis in the laboratory a team of scientists of the Universities of Jena and Erlangen-Nuernberg and of the Institute of Photonic Technology (IPHT) in Jena (Germany) made a huge step forward. The physicists and chemists were able to prove in their tests, that the first step already affects the efficiency of hydrogen generation.

Depth charge: Using atomic force microscopy to study subsurface structures

Over the past couple of decades, atomic force microscopy (AFM) has emerged as a powerful tool for imaging surfaces at astonishing resolutions - fractions of a nanometer in some cases. But suppose you're more concerned with what lies below the surface? Researchers have shown that under the right circumstances, surface science instruments such as the AFM can deliver valuable data about sub-surface conditions.

Advances in analysis using nanopore-based single-molecule mass spectrometry

National Institute of Standards and Technology (NIST) scientists have moved a step closer to developing the means for a rapid diagnostic blood test that can scan for thousands of disease markers and other chemical indicators of health. The team reports it has learned how to decode the electrical signals generated by a nanopore - a 'gate' less than 2 nanometers wide in an artificial cell membrane.

New technique can sense movement of single molecules over hours

Scientists can detect the movements of single molecules by using fluorescent tags or by pulling them in delicate force measurements, but only for a few minutes. A new technique by Rice University researchers will allow them to track single molecules without modifying them - and it works over longer timescales.
