Dr. Klaus Buhler, President of the German IVF Register, has reported the one-millionth treatment cycle in reproductive medicine recorded by the IVF Register in Germany this year. Presently, ninety per cent of all centers for in-vitro fertilization (IVF) in Germany collect data from reproductive treatments using RecDate Advance by Merck Serono - a database system developed by the IT consulting firm CRITEX, and marketed under the name MedITEX IVF.

When light is used to transmit information,  modulated light pulses travel along optical fibers, which can become weaker due to optical attenuation in the fiber and so are refreshed in signal regeneration stations along the way, where the signals are amplified and filtered.

But when light itself, or more precisely its optical frequency, is the information, and when this information is to be transmitted with extreme precision, conventional amplification techniques reach their limits.

A neutrino has a mass, physics says, but it is elusive to figure out and extremely hard to measure – a neutrino is capable of passing through a light year (about six trillion miles) of lead without hitting a single atom.

J' Recuse!

I must declare my interest right up front.

I am deeply concerned that we are leaving behind us a legacy of planet-wide pollution and despoilation for those who follow us as custodians of our planet.

I am not anti-oil.  I do, however, strongly favor regulation of the oil industry on the lines of the aviation industry.

U.S. District Judge Martin Feldman should have recused himself, rather than make statements such as:
