Process for the production of new metal complexes and their use as catalysts for the oligomerisation or polymerisation of olefin

Previously unknown nickel complexes with new amino-substituted and hydroxy-substituted phosphino-acetic acid ligands are suitable as catalysts for ethylene…

Europe scores new planetary success: Venus Express enters orbit around the Hothouse Planet

Yesterday, at the end of a 153-day and 400-million km cruise into the inner Solar System beginning with its launch on 9 November 2005, ESA’s Venus Express space probe fired its main engine at 09:17 CEST for a 50-minute burn, which brought it into orbit around Venus.

With this firing, the probe reduced its relative velocity toward the planet from 29,000 to about 25,000 km/h and was captured by its gravity field. This orbit insertion manoeuvre was a complete success.

Fermilab’s CDF scientists present a precision measurement of a subtle dance between matter and antimatter

Scientists of the CDF collaboration at the Department of Energy’s Fermi National Accelerator Laboratory announced today (April 11, 2006) the precision measurement of extremely rapid transitions between matter and antimatter. As amazing as it may seem, it has been known for 50 years that very special species of subatomic particles can make spontaneous transitions between matter and antimatter. In this exciting new result, CDF physicists measured the rate of the matter-antimatter transitions f

Scientists discover new genetic subtypes of common blood cancer

Varied gene signatures in multiple myeloma cells predict different outcomes, provide treatment targets

Scientists at Dana-Farber Cancer Institute and collaborators have identified four distinct genetic subtypes of multiple myeloma, a deadly blood cancer, that have different prognoses and might be treated most effectively with drugs specifically targeted to those subtypes.

A new computational tool based on an algorithm designed to recognize human faces plucked the fou

Next phase reached in definition of Mars Sample Return mission

ESA has taken a further step in preparing for participation in Mars Sample Return (MSR), the landmark mission to return samples from the Red Planet, with the announcement of the next phase of industrial activity.

The Phase A2 activity will address many critical issues and identify key areas in which Europe can participate in this flagship of the Aurora Programme.

The search for evidence of life outside the Earth is one of the fundamental goals of space exploration, and has been
