Read moreViscosity at the nanoscale: 50-year-old intriguing puzzle solved
At a snail's pace - this is how proteins should move inside living cells where viscosity of environment exceeds the viscosity of water even by million times. However, proteins move not much slower than in water! While looking for a solution to this puzzle, scientists from the Institute of Physical Chemistry of the PolishAcademy of Sciences discovered a new principle of physics.

Read moreDelayed 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 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.

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.

Read moreDepth 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.

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.
