Presidential candidate Beto O'Rourke reiterated his support for a mandatory gun-buyback program of assault-style rifles on Thursday and said, "Hell, yes, we're going to take your AR-15, your AK-47.""We're not going to allow it to be used against our fellow Americans anymore," the former Texas congressman said during the third Democratic presidential debate, hosted by ABC News."If the high-impact, high-velocity round, when it hits your body, shreds everything inside of your body because it was designed to do that so that you would bleed to death on a battlefield ... when we see that being used against children," O'Rourke said. He recalled talking to a woman in Odessa, Texas, who had watched her 15-year-old daughter bleed to death after she was shot by a man wielding an AR-15 late last month.O'Rourke's comments come in the wake of a string of mass shootings in the United States, including in his hometown of El Paso, where 22 people were gunned down at a Walmart in August. O'Rourke unveiled a proposal weeks after that shooting calling for a national gun registry, a nationwide gun licensing system and the mandatory buyback of assault-style rifles as part of his plan to curb gun violence and the rise of white nationalism.He received praise from his fellow Democratic contenders on Thursday night for his actions following the shooting in El Paso."The way he handled what happened in his hometown -- to look in the eyes," former Vice President Joe Biden said.Fellow Texan Julián Castro praised O'Rourke for "how well he has spoken to the passion and the frustration and the sadness" after the shooting."And Beto, God love you for standing in the middle of that tragedy," said Sen. Kamala Harris of California.Sen. Amy Klobuchar of Minnesota said, "I so appreciate what the congressman's been doing."Sen. Cory Booker of New Jersey needled O'Rourke later, saying he was sorry it had taken the El Paso shooting for O'Rourke to embrace the position Booker already held, backing a mandatory buyback and national registration.O'Rourke's support for gun licensing is a reversal from May, when he was asked about a similar proposal from Booker and said it "may be too far." 2191

Record high temperatures reportedly measured in Antarctica will take months to verify, the U.N. weather agency said Sunday.A spokesman for the World Meteorological Organization said the measurements made by researchers from Argentina and Brazil earlier this month have to undergo a formal process to ensure that they meet international standards.“A formal decision on whether or not this is a record is likely to be several months away,” said Jonathan Fowler, the WMO spokesman.Scientists at an Argentine research base 531

Sleep traits could be a risk factor for breast cancer, new research suggests. Women who said they preferred to get out of bed early were found to have a lower risk of breast cancer than those who stay up late.However, experts cautioned that other breast cancer risk factors such as alcohol consumption and being overweight have a greater impact than sleep and said there was no reason to change your sleep patterns.One out of 100 women who considered themselves morning people developed breast cancer, compared with two in 100 women who described themselves as evening people, according to the study, which was published Wednesday in the BMJ.The study also found that sleeping more than the average seven to eight hours per night was found to have a slightly increased risk of breast cancer. It also found there was little link with insomnia.Researchers used information from more than 400,000 women in two large data banks -- around 180,000 women from UK Biobank study and more than 220,000 women from the Breast Cancer Association Consortium study. Participants' preference for waking early or late was included in the data."It is important to note that these data do not suggest in any way that modifying sleep habits could eventually lead to a decrease in the risk of breast cancer," Luca Magnani, senior research fellow in the department of Surgery & Cancer at Imperial College London told the Science Media Centre."What they suggest is that it appears that the risk of breast cancer is associated with a genetic (thus not modifiable) trait that is in itself associated with a "morning" or "night" preference -- what we call 'larks' and 'owls'."According to 2016 figures from the 1700

Republican Greg Murphy will win in the special election to replace Walter Jones as the congressman from North Carolina's 3rd District, CNN projects.In another race on Tuesday, North Carolina state Sen. Dan Bishop will defeat Democrat Dan McCready in the North Carolina 9th District's special congressional election, giving Republicans a narrow victory in the GOP-leaning district where President Donald Trump won by 12 points in 2016.The race drew national attention as a potential 2020 bellwether, in a district that stretched from the Charlotte suburbs to the military town of Fayetteville. Trump and Vice President Mike Pence both made eleventh hour trips to the district on Monday in an effort to bolster Bishop.The "do-over" special election came after the state board of elections refused to certify the 2018 House race results in the district after fraud allegations, ordering a new election. 911
