Canada Border Services Agency (CBSA) figures  obtained by Montreal newspaper La Presse suggest 31% more US citizens were turned away last year than 2015. In 2016, 30,233 Americans were sent back at the boundary compared to 23,052 the year before. The report comes  amid concerns in Canada about travel to the US. La Presse also reports that in 2014, just 7,509 US citizens were refused entry to Canada. An immigration lawyer told the paper that the spike in people turned away was probably in part because of the increased sharing of data and information, including criminal records, between Canada and the US. The CBSA s...

1 hour ago   From the section US & Canada Share Image copyright REUTERS Image caption Mr Trump signed the order while flanked by coal miners President Donald Trump has signed an executive order rolling back Obama-era rules aimed at curbing climate change. The president said this would put an end to the "war on coal" and "job-killing regulations". The Energy Independence Executive Order suspends more than half a dozen measures enacted by his predecessor, and boosts fossil fuels. Business groups have praised the Trump administration's move but environmental campaigners have condemned it. Flanked by coal miners as he signed the order, the president said: "My administration is putting an end to the war on coal. "With today's executive action I am taking historic steps to lift the restrictions on American energy, to reverse government intrusion and to cancel job-killing regulations." During the campaign, he vow...

A powerful cyclone carrying winds of up to 263km/h (163 mph) has made landfall in Queensland, Australia. Cyclone Debbie, a category four storm, has left at least 45,000 homes without power and damaged buildings, although it is too early to say how many. PM Malcolm Turnbull told parliament he had activated a disaster response plan. More than 25,000 people were urged to evacuate their homes ahead of predictions the cyclone would be Queensland's most damaging  since 2011 . The system is expected to remain for several hours after crossing the coast between Bowen and Airlie Beach. In pictures: Debbie makes landfall "We are in for a long, tough day," said Queensland Premier Annastacia Palaszczuk. "The intensity and ferocity of the winds is going to be gradually increasing. Everyone is bunkered down." Image copyright EPA Image caption Cyclone Debbie could be the most powerful storm to hit the area since Cyclone Yasi in 2011 Electricit...

Image Caption: Scientists think NMN could be on the market in three to five years A drug that reverses ageing could be on the market in three years, scientists claim. In early experiments, the drug nicotinamide mononucleotide (NMN) had a dramatic rejuvenating effect on ageing mice. Researchers hope to begin testing the drug on clinical trial patients in the next six months. Lead scientist Professor David Sinclair, from the University of South Wales in Australia and Harvard Medical School in the US, said: "The cells of the old mice were indistinguishable from the young mice, after just one week of treatment. "This is the closest we are to a safe and effective anti-ageing drug that's perhaps only three to five years away from being on the market if the trials go well." Image Caption: Clinical trials on NMN are expected to start in the US this year NMN works by boosting levels of NAD+, which helps repair DNA. Accumulated DNA damage is a major dr...

Around 10 million workers are at risk of seeing their jobs taken over by robots over the next 15 years, according to a new report. But the research from PwC said new artificial intelligence (AI) related technologies would also boost productivity and generate additional jobs elsewhere in the economy. The report said up to around 30% of existing UK jobs were susceptible to automation by the 2030s. Sectors such as transport and manufacturing were at the biggest risk with half of jobs at "potential high risk" of disappearing, according to the analysis. Other areas such as education and health and social work were seen as less at risk. Men - especially those with lower levels of education - were more likely to see their jobs automated than women, being more heavily represented in those sectors most under threat. The research suggested automation related to AI and robotics would not necessarily reduce total employment in the long run. But it could widen income ine...
