Facebook's Mark Zuckerberg and Sheryl Sandberg will not attend a hearing in Ottawa on Tuesday, despite receiving summonses from the Canadian parliament, Facebook confirmed on Monday.The decision could result in the executives being held in contempt of parliament, the senior Canadian politician who sent the summons told CNN.Both executives received formal requests from the Canadian Parliament earlier this month tied to a gathering of an international committee examining Silicon Valley's impact on privacy and democracy. Zuckerberg and Sandberg have testified before the United States Congress on the subject.On Monday night, Bob Zimmer MP, the chair of the committee, said that Facebook had not told the committee whether its two most senior executives would be attending. He said committee members learned on CNN that Zuckerberg and Sandberg would not testify.A Facebook spokesperson disputed that on Tuesday morning, saying the company had told the committee it would be sending Kevin Chan, its head of public policy for Facebook Canada, and Neil Potts, its director of public policy, to the meeting. The spokesperson added the company had been in ongoing communication with the committee.Lawmakers from at least ten countries, including the United Kingdom and Australia, are expected to attend the meeting, which is the second of its kind. The first meeting of the committee last year in London resulted in the release of 1441

Hurricane Dorian -- the strongest storm anywhere on the planet this year -- is leaving "catastrophic damage" in its wake as it makes its way across the Bahamas, where it's claimed at least one life.The monster Category 5 storm made landfall on the eastern end of Grand Bahama Island Sunday night and will continue to pound the island for most of Monday as it creeps toward the southeastern US coast.The death of an 8-year-old boy is being reported by Bahamas news outlets Eyewitness News and Bahamas Press.The boy's grandmother, Ingrid McIntosh, told Eyewitness News that her grandson died on Abaco Island. She said her 31-year-old daughter found the body of her son, who she believed drowned in the rising waters. McIntosh said her granddaughter is also missing."I just saw my grandson about two days ago," she said. "He told me he loved me. He was going back to Abaco, he turned around and said, 'Grandma, I love you.'"CNN has contacted Bahamian authorities, who have not yet confirmed these reports. 1014

Having children will make you happier than staying childless, according to a new study, but not until later in life, when they have flown the nest.A team of researchers at Heidelberg University in Germany found that parents tend to be happier than non-parents in old age, but this only holds if their kids have moved out.Previous research has suggested that parenthood, social networks and marital status affect the well-being and mental health of older people, and this latest study looks at the effects of family status.Scientists asked 55,000 people age 50 and over from 16 European countries about their mental well-being, and results suggest "the positive aspects of parenthood dominate when getting older."One of the biggest factors is that children become a form of social support, and the researchers point out that social support networks are associated with greater happiness and less loneliness and can act as a buffer against stressful events."The results suggest that the finding of a negative link between children and well-being and mental health may not generalize to older people whose children have often left home already," the study says."As stress associated with balancing the competing demands of childcare, work and personal life decreases, once people get older and their children leave (home), the importance of children as caregivers and social contacts might prevail."However, children who still live at home are shown to have a negative effect on well-being.Christoph Becker, who formed part of the research team, told CNN that having a social network corresponds to greater life satisfaction, but that doesn't have to come from children.Older people without children could get similar benefits from other close social connections with whom they can share issues and problems, he added.Becker told CNN there are plans to track happiness for the same people over multiple years to study how well being evolves as people get older."Literature has suggested that there might be U-shaped connection between age and happiness: people become less happy in middle age, but more happy in older age," said Becker."We want to test if we find a similar relationship in our data, depending again on parenthood and social networks."Previous research on the subject has been mixed.A report by Princeton University and Stony Brook University published in the Proceedings of the National Academy of Sciences found "very little difference" between the life satisfaction of parents and people without children, once other factors -- such as income, education, religion and health -- were factored out, said Arthur Stone, one of the study's co-authors.Another study, by the Open University in England, found childless couples were happier with their relationships and their partners than parents were, and were doing more work on their relationships than parenting couples. 2895

Highways often cause parents to worry about their children's physical safety, yet there may be other important concerns. Young children who live near a major roadway are twice as likely to score lower on tests of communications skills than those who live farther away, new research indicates."We know that living close to major roadways — interstate highways or state highways — is associated with high air pollution," said 436
