The sale of PIramed to Roche for $185 million means a 'very substantial cash return' to investors in Merlin III, the investment fund created by Sir Christopher five years ago.

Merlin Biosciences were co-founding investors in PIramed at the outset in 2003 with JP Morgan. Merlin, with the founders of the company, also selected the CEO, the management team, built the board of directors and continued to provide ongoing funding and strategic advice to the company.

Female fruit flies sometimes choose males who are aggresive, sometimes choose males who do not fight at all, and sometimes choose males for no reason science can explain, write a team of biologists, and the findings help explain the large variation in aggressiveness in most species, including humans.

So females are unpredictable, which means the fittest males don’t always get the girl. This explains why males don't evolve towards super-aggressiveness.

“If aggression makes you more likely to father children, all males should be selected to be very aggressive. Male fruit flies (like humans and other animals) show a lot of genetic variation in aggression, and we wanted to find out why,” explained study leader Brad Foley, a post-doctoral researcher at USC.

CALGARY, Canada, April 15 /PRNewswire/ -- Oncolytics Biotech Inc. (TSX: ONC) (NASDAQ: ONCY) announced that a poster presentation by Dr. Anders Kolb of the Nemours Center for Childhood Cancer Research entitled "Radiation in Combination with Reolysin for Pediatric Sarcomas" was presented today at the American Association for Cancer Research (AACR) Annual Meeting. The meeting is being held in San Diego, California from April 12-16, 2008.

"The combination of REOLYSIN(R) with radiation is certainly favourable," said Dr. Kolb. "Statistically significant improvements in event-free survival are seen in mice treated with the combination when compared to either therapy alone."

Huge star streams in the outskirts of two nearby spiral galaxies have allowed astronomers to obtain a panoramic overview of ' galactic cannibalism' similar to that involving the Sagittarius dwarf galaxy in the vicinity of the Milky Way.

The detection of these immense stellar fossils confirms the predictions of the cold dark matter model of cosmology, which proposes that present-day grand design spiral galaxies were formed from the merging of less massive stellar systems.

The first of these debris structures surrounds the galaxy NGC 5907, located 40 million light-years from Earth and formed from the destruction of one of its dwarf satellite galaxies at least four billion years ago.

The electric solar wind sail developed at the Finnish Meteorological Institute has moved rapidly from invention towards implementation. Electric sail propulsion might have a large impact on space research and moving in space in general.

The electric solar wind sail developed by Dr. Pekka Janhunen at the Finnish Meteorological Institute might revolutionise travelling in deep space. The electric sail is a Finnish invention which uses the solar wind as its thrust source and therefore needs no fuel or propellant. The solar wind is a continuous plasma stream emanating from the Sun. Changes in the properties of the solar wind cause auroral brightening and magnetic storms, among other things.

A team of researchers from Case Western Reserve University has found that gravitational radiation—widely expected to provide “smoking gun” proof for a theory of the early universe known as “inflation”— can be produced by another mechanism.

According to physics scholars, inflation theory proposes that the universe underwent a period of exponential expansion right after the big bang. A key prediction of inflation theory is the presence of a particular spectrum of “gravitational radiation”-- ripples in the fabric of space-time that are notoriously difficult to detect but believed to exist nonetheless.

“If we see a primordial gravitational wave background, we can no longer say for sure it is due to inflation,” said Lawrence Krauss, the Ambrose Swasey Professor of Physics and Astronomy at Case Western Reserve.
