Washington (CNN) The advertised purpose of President Barack Obama's pre-vacation news conference Thursday was to highlight gains in the war against ISIS in Iraq and Syria with the Pentagon as a backdrop. But for all his talk of terrorism, Russia and other geopolitical challenges, the underlying argument he wanted to make was clear: it's a serious business being commander-in-chief and the Republican who wants his job isn't fit for the Oval Office. Obama ridiculed Donald Trump's recent suggestion that the election system could be rigged, called on the candidate to act like a president since he's soon to be briefed on confidential information and implied that he didn't believe the billionaire businessman could be trusted with America's nuclear codes.Obama hit out at Trump just two days after branding him unfit to be commander in chiefTrump and Clinton are expected to soon start getting classified intelligence briefings

Los Angeles (CNN) -- Dr. Conrad Murray defended his appellate lawyer from "a slew of disparaging remarks" just days before she files the appeal of the doctor's involuntary manslaughter conviction in Michael Jackson's death. CNN has obtained sections of that 300-page appeal, including the defense argument that the trial judge erred by not allowing the testimony of Dr. Arnold Klein, a dermatologist the defense contended addicted Jackson to Demerol in his last weeks.

Hong Kong generally gets a bad rap when it comes to infectious diseases. Grabbing headlines during recent bird- and swine-flu outbreaks, its proximity to Mainland China as well as its unenviable status as the worst-affected city during the 2003 SARS outbreak, Hong Kong has been central to several global pandemic fears in recent years. It hasn't even escaped fictional outbreaks -- the 2011 movie "Contagion" had patient zero Gwyneth Paltrow bring back an unwelcome souvenir from a business trip to the city. But this bad biological baggage may come in handy. The unwelcome distinction of being home to over one fifth of the world's SARS cases, and two fifths of the 774 fatalities from SARS meant Hong Kong quickly developed and implemented a very sophisticated disease control and epidemiology infrastructure.Expertise gained in Hong Kong during SARS epidemic helpful in battling MERS virusOver 100 MERS deaths have now been reported as cases spikeHong Kong and Chinese researchers looking at "promising" antibodies as MERS cure
