Jackson medic denies manslaughter

About Entertainment - Magazine -

Michael Jackson’s former doctor has denied a charge of involuntary manslaughter over the singer’s death, at a court in Los Angeles.

Dr Conrad Murray is expected to be bailed after pleading not guilty to "unlawfully, and without malice, killing Michael Joseph Jackson".

A judge must decide whether to proceed to trial. A conviction could bring a jail term of up to four years.

Jackson died at his home last June at the age of 50.

His death was ruled as homicide, mainly caused by the anaesthetic Propofol.

A cocktail of drugs - including sedatives Midazolam and Diazepam, the painkiller Lidocaine and the stimulant Ephedrine - were also detected in his body, a coroner confirmed.

Prosecutors filed one count of involuntary manslaughter.

Members of Michael Jackson’s family, including father, Joe, several brothers and sister LaToya, were in court where Dr Murray arrived shortly before 1300 local time (2100 GMT).

When asked by a reporter what he thought about Dr Murray being charged with involuntary manslaughter, Michael Jackson’s brother, Jermaine, said simply: "It’s not enough".

Joe Jackson said only "looking for justice".

Legal fight

Dr Murray had been hired to be Jackson’s personal physician last spring as the singer prepared for his comeback concerts in London.

Enceladus water story reinforced

About Science-Nature -

Enceladus (Nasa)

Ice particles and water vapour spew from cracks in the moon’s icy surface


There seems little doubt that Saturn’s moon Enceladus hides a large body of liquid water beneath its icy skin.

The Cassini probe, which periodically sweeps past the little moon, has returned yet more data to back up the idea of a sub-surface sea.

This time, it is the detection of negatively charged water molecules in the atmosphere of Enceladus.

On Earth, such ions are often seen where liquid water is in motion, such as waterfalls or crashing ocean waves.

There are no "rollers" on the moon but it does have a very active region near its south pole where water vapour and ice particles shoot through cracks in the surface and rise high into the Enceladian sky.

"We see water molecules that have additional electrons added," explained Andrew Coates from University College London’s Mullard Space Science Laboratory.

"There are two ways they could be added - from the ambient plasma environment, or it could be to do with friction as these water clusters come out of the jets, like rubbing a balloon and sticking it on the ceiling," he told BBC News.
