question:
"We -LSB- Republicans -RSB- have to win in November 2016 ," Cruz added later in the program . 
Cruz 's father , a pastor , is also expected to help the 44-year-old first-term senator make inroads with these voters . 
Texas Republican Sen. Ted Cruz , ticking off a litany of President Obama policies he opposes , promised Monday to return to a government by Constitution and "stand for liberty" as he officially announced his 2016 presidential bid . 
Cruz is already a familiar figure on the circuit for presidential hopefuls , having made repeated visits to the early voting states , the big conservative activist conferences and more . 
Cruz , speaking to an energetic crowd of students at Liberty University in Lynchburg , Va. , drew from his background to address his faith and what he sees for the future of the country . 
By announcing what has long been obvious , Cruz triggers a host of accounting and reporting requirements about money he is raising and how he is spending it . 
Cruz continued his pledge by telling the crowd to "imagine a president who says I will honor the Constitution and under no circumstances will Iran be allowed to acquire a nuclear weapon ." 
For his announcement , Cruz bypassed Texas , which he represents in the Senate , as well as early nominating states such as New Hampshire , where Mitt Romney kicked off his own campaign for the GOP nomination in 2012 , and Iowa . 
The son of an American mother and Cuban-born father , Cruz is positioning himself to become potentially the nation 's first Hispanic president . 
While he was born in Canada , two lawyers who represented presidents from both parties at the Supreme Court recently wrote in the Harvard Law Review that they think Cruz meets the constitutional standard to run . 
Cruz spoke on the fifth anniversary of Obama 's health care law -- legislation that prompted Cruz to stand for more than 21 hours in the Senate to denounce it in a marathon speech that delighted his Tea Party constituency and other foes of the law . 
Cheers rose in the hall when Cruz reminded the crowd Monday that Liberty University filed a suit against the law right after its enactment . 
Should he fail to win the nomination or the presidency , Cruz would retain his Senate seat through 2019 . 
Cruz earlier declared his candidacy via a Twitter post early Monday , becoming the first major candidate to officially declare . 
"It 's time to get in there ," Cruz told Fox News ' Sean Hannity Monday night . 
A 30-second video accompanying the tweet featured Cruz speaking over a montage of farm fields , city skylines and American landmarks and symbols , calling on "a new generation of courageous conservatives to help make America great again ." 
By getting in early -- and at Liberty -- Cruz was hoping to claim ownership of the influential and highly vocal corner of the Republican Party for whom cultural issues are supreme . 
"I 'm ready to stand with you to lead the fight ," Cruz says as the video concludes . 
Cruz , a divisive figure in his own party , is not expected to be the sole GOP contender for long .
answer:
Sen. Ted Cruz announces presidential bid , vows to ` stand for liberty ' . 


question:
NASA hopes to take advantage of the island’s erupting volcano — Mount Agung — to study the effects the belching beast has on Earth. They hope that by tracking  Mount Agung’s  eruption  they’ll be able to learn more about how chemicals released into the atmosphere might be used to fight climate change.
After  Mount Agung  woke up and began erupting at the end of November  it has been consistently pouring steam and gas into the atmosphere. This is pretty typical though some volcanoes are so powerful they can cause what is known as a “volcanic winter” that stretches near and far after they erupt.
For researchers   Agung  could be their chance to figure out just how volcanoes affect the climate like Mount Tambora did.
The research into  Agung  began with a ten-hour flight away from  Agung   when a volcano in the Philippines erupted in a big way in 1991. Scientists had picked up the trend during a smaller scale eruption in 1982 of the El Chichon volcano in Mexico  but nothing quite like what they saw at Mount Pinatubo  in the Philippine  dubbed the biggest eruption of the 20th century.
 Mount Agung’s  eruptions bear similar trademarks to Pinatubo which is why NASA is hoping to send balloons into the air fitted with gadgets to measure the effects of the volcanic eruption on the Earth’s atmosphere. NASA hopes to study the effects for years to come.
If  Agung  was to blow again with a similar fury to Pinatubo’s 1963 eruption  it could pump enough sulphur dioxide into the atmosphere to have a significant cooling effect and temporarily damage the ozone layer.
Alan Robock  a Rutgers University researcher who models the effects of eruptions and who has been involved in discussions about the rapid-response project told The Times that though it’s hard to predict  whether it’s Mount Agung or not  an eruption is inevitable.
answer:
An erupting volcano could save Earth from humanity


question:
TAIPEI (Reuters) - Nvidia Corp chief executive Jensen Huang said on Thursday artificial intelligence would enable fully automated cars within 4 years  but sought to tamp down expectations for a surge in demand for its chips from cryptocurrency miners.

âIt will take no more than 4 years to have fully autonomous cars on the road. How long it takes for the vast majority of cars on the road to become that  it really just depends â  Huang  told media after a company event in Taipei.
But  Huang  joined peers taming expectations of strong revenue growth from a wave of interest in cryptocurrencies. Advanced Micro Devices Inc expected this week that there will be some leveling off of cryptocurrency demand. [nL4N1MZ5RP]
âRevenue for us in crypto is over $100 million a quarter. For us  itâs a small percentage... Itâs obviously not a target market â  Huang  said.
