 The upside of longevity….
Biotech researchers can now produce new heart tissue with off-the-shelf
inkjet technology, improving precise cell placement and, in effect,
“printing” the tissue. Nanotechnology also offers new ways to replace
tissue, with damaged cells being rebuilt one atom at a time to create a
flawless, brand new, youthful cell.
These are just two examples of a host of breakthroughs hitting the
headlines in the scientific and medical press around the world. So
where will they take us? Are we finally looking at the dream of
eternal youth and perfect health becoming reality? And if so, what will that mean?

 Terahertz (THz) radiation, or far-infrared light, is potentially very useful for security applications, as it can penetrate clothing and other materials to provide images of concealed weapons, drugs, or other objects. However, until now THz scanners have had to be very close to the objects they are imaging. Now US researchers from the Massachussetts Institute of Technology have demonstrated a real-time Terahertz (THz) radiation imaging system that can operate from as far as 25 metres away from its subject, according to a report from the Optical Society of America.
