#Scientists Develop Entirely Artificial Molecular Pump The new machine mimics the pumping mechanism of life-sustaining proteins that move small molecules around living cells to metabolize and store energy from food.
when irradiated with laser light of a specific wavelength. One such'chameleon protein'is called Dendra 2,
when it is irradiated by intensive violet or ultraviolet (UV) laser light. Two-laser combination Dempsey and Pantazis specifically discovered that
when Dendra 2 is irradiated by both a blue and a red laser at the same time,
the protein's colour can also change to red. For this dual-colour illumination low intensity laser light is sufficient.
In contrast to high intensity violet or ultraviolet (UV) irradiation it does not damage living cells.
when used individually, two different laser beams cannot change a chameleon protein's colour. But when the two beams are combined
the proteins that are activated not at the same time by the two lasers retain their original colour. The researchers have developed a simple and inexpensive colour filter,
which can be used with the conventional confocal laser microscopes that are found in many biomedical research institutes.
When mounted between the laser source and object the filter divides the laser light into separate blue
and red beams that are directed on to a small focal point on the object. Examination of dynamic processes In the case of the zebrafish larva,

a laser is focused onto a small spot on the sample by each microlens. The laser light causes the sample to fluoresce,
emitting specific wavelengths of light that differ depending on the molecules that are present. This fluorescence is imaged then back onto the camera.
These dyes respond to laser light by fluorescing at specific frequencies so they can be detected and localized with high precision.
Modern telecommunications use laser light with a wavelength of one and a half micrometers, which accordingly is the lower limit for the size of a modulator.

When a powerful laser interacts chemical and biological molecules, the process can excite vibrational modes of these molecules and produce inelastic scattering, also called Raman scattering, of light.
As the beam hits these molecules, it can produce photons that have a different frequency from the laser light.
While rich in details, the signal from scattering is weak and difficult to read without a very powerful laser.

The process is distinct from micro laser sintering or direct metal laser sintering, both of which use a laser in combination with metal powders to create new structures.
The key to this breakthrough in printing metals seems to be using a higher energy laser than in previous attempts.
This allows for the creation of so-called"fast droplets"that quickly deform into flattened disks
when they impact the substrate. Earlier experiments used lower energy lasers, creating drops of metal that maintained a more spherical shape
and led to the creation of a stack that was less stable. The method still requires some refinement as the high-energy laser currently causes droplets to also land next to the desired placement location.
