Murder charge John Downey to be questioned on historical offences

first_imgA 67-year-old man charged with murdering two British soldiers in 1972 is to be questioned about other alleged historical offences.John Downey was before Belfast Magistrates’ Court for an application to be released into police custody.Detectives were given up to three days to interview him on undisclosed matters, unrelated to the current case against him. Mr Downey’s solicitor opposed the move, calling it “unnecessary and excessive”.The defendant is currently charged over a car bomb attack which killed Ulster Defence Regiment members Alfred Johnston and James Eames in Enniskillen, County Fermanagh, in 1972.Mr Downey, with an address in Creeslough, County Donegal, was extradited to Northern Ireland from the Republic of Ireland earlier this month.Murder charge John Downey to be questioned on historical offences was last modified: November 1st, 2019 by Staff WriterShare this:Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on LinkedIn (Opens in new window)Click to share on Reddit (Opens in new window)Click to share on Pocket (Opens in new window)Click to share on Telegram (Opens in new window)Click to share on WhatsApp (Opens in new window)Click to share on Skype (Opens in new window)Click to print (Opens in new window)last_img read more

Amazing Cell Tricks: Contour Map Navigation

first_imgWatch a cell divide, and if things go well, it always divides in the middle.  How does a cell figure out where its middle is?  It follows its contour map.  PhysOrg titled its entry, “Dividing cells find their middle by following a protein ‘contour map’.”    Cell division, or cytokinesis, is a precisely-controlled operation that is vital to all of life (see 12/28/2007).  Each molecule in the cell has to know its proper position during each stage, and how to get there.  For some molecules, crossing a cell is like navigating a countryside over a long distance.  Human navigators, we know, need a topo map printed out or software or GPS.  They also have to know where they are trying to go, and have sensory equipment (eyes, kinesthetic sense) to gauge contour lines on a hill or valley.  How can a cell pull off this feat?  They use periodically-placed signaling molecules that act like beacons.    The team measured all over the cell the positions of important sensory molecules involved in cell division.  They detected a gradient – like the slope of a hill – that was greatest at the center, where the site of cleavage must be located.  The proteins and enzymes that create the cleavage furrow are thus able to sense the contours and arrive at the right spot to begin cleaving the cell in two.Wonderful stuff, that molecules are so precisely choreographed that they can arrive in formation like band players on a football field.  The explanation was duly marvelous, but… it seems to beg the question.  What tells the signalling molecules where to go and where the center is?  If Dan found the mountaintop because Bob hollered to him from the summit, how did Bob find it?  Clearly more is going on than scientists have thus far been able to figure out.(Visited 10 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more
