This is the end of a controversy a century old and on the propagation of light in the dielectric. A group of Taiwanese researchers has vindicated the theoretical physicist Max Abraham against the great mathematician Hermann
Minkowski.

All the crucial proteins in our bodies must fold into complex shapes to do
their jobs. These snarled molecules grip other molecules to move them around, to
speed up important chemical reactions or to grab onto our genes, turning them
"on"...

Using tiny gold particles embedded with dyes, researchers have shown that they can identify tumors under the skin of a living animal. These tools may allow doctors to detect and diagnose cancer earlier and less invasively
Studded with...

By using lasers to etch data onto microbial proteins, researchers
at the University of Connecticut may have demonstrated a way to produce
rewritable holographic memory. Holographic memory stores data in three
dimensions instead of two...

Researchers at UC Santa Barbara have announced they have built the world's
first mode-locked silicon evanescent laser, a significant step toward combining
lasers and other key optical components with the existing electronic
capabilities in...

In order to observe movements on an atomic scale, there is necessary to be
able to have a light for very low wavelength, in the ultraviolet ray even in the
field of x-rays. At present, it is one laser whose luminous flashes are emitted
in...

Cornell researchers have answered a fundamental question about how two
strands of DNA, known as a double helix, separate to start a process called
replication, in which genes copy themselves. The research, published in the
current issue of...

Lasers
have become a standard feature of surgical interventions, be it to alleviate the
breathing difficulties of snorers or to treat prostate problems. A new diode
laser is ideally suited for use in soft tissue surgery. It has the advantage of...

Producing three-dimensional polymer line
structures as small as 65 nanometers wide just became easier with new two-photon
absorbing molecules that are sensitive to laser light at short wavelengths,
allowing researchers to create them without...
