[Q]: On Friday   Tyler Barriss  made  his  first court appearance and Sedgwick County District Court judge Faith Maughan set  his  bond at $500 000.  He  also was charged with giving false information in notifying emergency services and falsely reporting a felony.
 He  was arrested in South Los Angeles on Dec. 29  one day after Wichita police received a 911 call from a man saying  his  father had been shot in the head and that  he  was holding  his  mother and sibling at gunpoint.  The caller  also claimed gasoline was poured on the home and  he  âmight just set it on fire.â
 Barriss  was extradited to Kansas and held in the Sedgwick County Jail on Thursday afternoon.  He  wrote in a financial affidavit that  he  hasnât worked for six months.
 Barriss  reportedly called after a feud between between people playing Call of Duty on Dec. 28. Finch and  Barriss  had nothing to do with the game  police have said  but gamers involved asked  Barriss  to make the 911 call.
One week before the killing in Kansas   Barriss  was charged with mischief and fraud by police in Calgary  Canada  for a similar prank.
In an interview with KWCH TV   Barriss  said âI never intended for anyone to get shot and killed.â
 He  added: âThere is no inspiration. I donât get bored and just sit around and decide Iâm going to make a SWAT call.â

[Q]: This weekend's bloodshed broke out Sunday in the southern port city of Aden  where forces loyal to the separatist Southern Transitional Council traded gunfire with loyalists of  President Abed Rabbo Mansour Hadi . The scattered fighting has claimed at least 12 lives and injured scores more.
The two sides had shared an uneasy alliance since 2014  when they were united in their opposition to the Houthi rebels who seized cities in the country's northwest  including the capital  Sanaa. Together  the STC and  Hadi 's forces managed to repel the Houthis from Yemen's southern governates and Aden  the large city where Hadi's government had presided since its ouster from the capital.
As Reuters notes  the fighting follows the expiration of a deadline set last week by the southern separatists. Irate at what they call corruption and the deep erosion of public services in the areas still governed by Hadi  the STC had delivered him an ultimatum: shake up the cabinet and sack bin Daghir or face ouster. That deadline came and went without sign that  Hadi  had any intention of complying.
The new fault that has opened between  Hadi  and  his  erstwhile allies in the STC adds another dimension to a war already packed with a dizzying array of players â and a long  tortuous history dating back at least to 1990. That's when South Yemen  a formerly independent state with Aden for its capital  agreed to unification with its northern counterpart. The union has never quite been an easy one  strained by a 1994 civil war and more recently  calls for greater autonomy in the south.
Add to that latent friction the bloodshed of recent years  which has seen Yemen's internal conflicts take on the character of a proxy war among competing powers in the Gulf region. The Houthis  a Shiite group based in the northwest  have been backed by Iran  while Saudi Arabia has led a coalition conducting an air campaign since 2015 supporting  Hadi  and  his  Sunni allies.

[Q]: Fernandez  a professor at the Georgia Institute of Technology  said that the demonstration  which he repeated with other bills provided by a reporter  showed both how pervasive cocaine was in the United States and how sensitive his machines were.
 They can instantly identify the chemical makeup of food  drugs and just about anything placed in front of their stainless-steel aperture. The uses of the machines  known as mass spectrometers  are manifold -- the federal Department of Homeland Security has commissioned Fernandez to study whether the technology can help sniff for explosives at airports.
 But Fernandez's main focus is counterfeit pharmaceutical drugs  especially in poorer countries  where government regulation is weak. He is part of an informal group of researchers and government officials spanning Africa  Asia and the United States who have teamed up with Interpol  the international police agency  to use cutting-edge technology in tracking fake drugs that claim to treat malaria. Counterfeit malaria drugs are of particular concern because of the scale and severity of the disease -- it kills more than 2 000 children a day in Africa alone -- and fears that fake or substandard malaria drugs are aggravating a growing problem of drug resistance.
 A scientific breakthrough in 2005 added an "ion gun" to the machines and allowed Fernandez to check hundreds of pills a day. A technician simply holds the sample -- a pill  dog food or a dollar bill  for example -- up to the machine  which emits a jet of helium gas and captures a minute amount of the material  instantly identifying its components.
 Contrary to the common belief that counterfeit drugs are just sugar pills  Fernandez said  most fakes have some level of active ingredient. Many contain the cheap and readily available pain reliever paracetamol  which might temporarily soothe some symptoms but will not fight the underlying disease.
 Mass spectrometers may have a role in weeding out some of these counterfeits. Fernandez  of Georgia Tech  is using them to test whether mosquito nets treated with insecticide  a crucial way to combat malaria  are genuine.
 With time  though  Fernandez hopes  costs will come down far enough that machines could be installed in local pharmacies.
 "I always dream that at some point the end-consumer will be able to check " Fernandez said. "You put your tablet in front of a machine and you get a red light or a green light. That would be the end of counterfeit drugs."
