[Q]: The event took place at the RDS Arena in Dublin  Ireland this weekend. The event was organised by the EFDD (Europe of Freedom and Direct Democracy) group and featured guest speakers including Brexit campaign leader Nigel Farage  Irish journalist John Waters  Professor Anthony Coughlan  Dr. Karen Devine  Cormac Lucey and Councillor James Charity. The event was moderated by the EFDD groups communications director Hermann Kelly.
After Waters’s speech  UKIP MEP Nigel Farage appeared to discuss Brexit and the state of the European Union. The veteran campaigner stated during his speech that Brexit was the proudest moment of his career  and he referred to the EU as a “con from the very start” and questioned what was happening in the politics of Ireland and who was representing the country abroad.
 Farage  asked  “What on earth is going on in the politics of this country? … How much more humiliated can the Irish nation be than for years being run by the Troika?”
 Farage  also noted that Ireland was now a net contributor to the EU  stating: “You are paying into the European budget and your Taoiseach said in Strasbourg the other week he is happy for Ireland to pay even more into the European budget… Are you pleased about that?”
Breitbart London has published an exclusive interview with  Farage  which can be read here.
Hundreds packed the RDS auditorium to watch the event  fans of the UK MEP were present throughout the crowd  some even donning T-shirts featuring  Farage ’s face 
 Farage  left the stage stating that while it was now up to Ireland to decide their fate in the EU  he would be happy to “hop on a plane to Dublin ” if he could be of any help in the future. Following  Farage ’s speech  the crowd rose to their feet giving the politician a standing ovation

[Q]: "Bush wanted to do the right thing by fulfilling this humanitarian impulse ," says Chow . 
In so doing , Chow contends , Bush paved the way for an era in which global health assistance has become a prominent new instrument of U.S. statecraft . 
By contrast , only a few Americans have ever heard of PEPFAR , the U.S. President 's Emergency Plan for AIDS Relief , which President Bush announced in his State of the Union address in 2003 . 
The name might surprise you : it 's George W. Bush . 
That 's partly because the United States has done very little to publicize the success of PEPFAR , and partly because the Bush presidency was overshadowed by much more high-profile aspects of his foreign policy -LRB- such as the invasion of Iraq -RRB- . 
Indeed , Bush still enjoys high popularity ratings in Africa , where he 's widely regarded as one of the continent 's great benefactors . 
At the same time , I think it 's a tragedy that the foreign policy shortcomings of the Bush administration have conspired to obscure his most positive legacy -- not least because it saved so many lives , but because there 's so much that Americans and the rest of the world can learn from it . 
"Bush did more to stop AIDS and more to help Africa than any president before or since ," says New York Times correspondent Peter Baker , who 's writing a history of the Bush-Cheney White House that 's due to appear in October . 
If it were n't for Iraq , it would be one of the main things history would remember about Bush , and it still should be part of any accounting of his presidency ." 
In his 2003 speech , President Bush called upon Congress to sponsor an ambitious program to supply antiretroviral drugs and other treatments to HIV sufferers in Africa .

[Q]: "The areas that are getting brighter rapidly are developing countries " says  Christopher Kyba  a researcher at the German Research Centre for Geosciences in Potsdam . "So a lot of places in South America  Africa and Asia are brightening really  really rapidly  up to 10 percent or more per year  even  in some cases."
With new solid-state lighting technology becoming available  some areas have started making a switch to LEDs. And because this satellite is not able to see all of the light emitted by LEDs   Kyba  says the brightening that's actually happening is probably greater than what's been measured.
"For the United States  for example  we don't see much of a change. But we know that a lot of LEDs are going in. And that means that the United States is almost certainly getting brighter  in terms of how people see the world with their human eyes "  Kyba  explains.
Some have suggested that energy-savings from LEDs will reduce the cost of lighting. But the researchers found that "as light gets cheaper  we use more of it  nearly proportionately to the rate at which it's getting cheaper  " Kyba  says.
On a global or national scale  all this wasted light is expensive   he  says: "It costs a lot of money to radiate that light into space and it's not doing anybody any good."
 He  and others argue that lighting efforts must be well-designed to reduce the amount of light going out into space while still providing a safe and comfortable experience for people on the ground who need to see at night.
The rapid increase in night lighting has been a profound change  a kind of global experiment  that has happened in just the last 100 years. "My mum  for example  grew up on a farm in Saskatchewan  in a time before they had electrification  " Kyba  says. "So  she  grew up with an amazing starry sky  and now  she  lives  within one lifetime  under a very light-polluted sky."
