Photograph: Barbara Walton/EPA Nicole Puglise @nicolepuglise More than 1,000 Russian athletes benefitted from state-sponsored doping More than 1,000 Russian athletes across more than 30 sports were involved in or benefited from state-sponsored doping between 2011 and 2015, according to a second report on the subject by the respected Canadian law professor Richard McLaren. Speaking in London, McLaren said he had found "an institutional conspiracy across summer, winter and Paralympic sports" in Russia between 2011 and 2015 and "a cover-up that operated on an unprecedented scale".

More than 1,000 Russian athletes benefitted from state-sponsored doping Who's who in Trump's cabinet Tom McCarthy has your rundown of who has been nominated for positions in Donald Trump's cabinet so far, as well as the non-cabinet roles that won't require confirmation by the Senate – from retired Gen James Mattis as secretary of defense to Elaine Chao as secretary of transportation. Trump's recent appointments of fast food executive Andy Puzder to head the US Department of Labor and Scott Pruitt as administrator of the Environmental Protection Agency have faced criticism. Pruitt has supported fossil fuel companies, sued the EPA and questioned that climate change is spurred by human activity. Within the agency, one scientist said that Pruitt risks being an "unprecedented disaster" for the natural world and public health. Trump's cabinet picks: here are all of the appointments so far Hillary Clinton warns against fake news In a speech at the Capitol yesterday, Hillary Clinton warned of the "real-world consequences" of fake news, alluding to an incident over the weekend in which a gunman opened fire at a Washington DC pizzeria over a false story. "It is a danger that must be addressed and addressed quickly," Clinton said at a tribute to departing Senate minority leader Harry Reid. She also joked about all of those selfies in the woods. Clinton was joined by Vice-president Joe Biden and congressional leaders from both parties to bid farewell to Reid, who leaves the chamber after 30 years in the Senate. Hillary Clinton warns fake news can have 'real world consequences' US scrambles to respond to surge of migrants at the border A spike in crossings at a previously quiet sector of the US-Mexico border "stems perhaps in part from the fear that Donald Trump will build a mighty wall. But it is mainly a consequence of continuing violence and economic distress in Central America, that migrants say make staying at home a riskier bet than trying to cross into the US, whatever the president-elect may say or do", Tom Dart writes from the Rio Grande Valley. US government scrambles to respond to surge of migrants at Mexico border Ohio 'heartbeat' abortion bill could be test case for overturning Roe v Wade The Ohio state legislature passed a new anti-abortion "heartbeat" bill that would ban terminations from as early as six weeks, the most severe restrictions in the country. Politicians say they were motivated to push through the bill by Trump's win, believing they might find a more friendly US supreme court that would uphold the law. If passed by Governor John Kasich, the bill could serve as a test case for the limits of constitutional protections of abortion – though activists on both sides of the issue doubt that strategy is likely to succeed.

Images of Charleston shooting aftermath shown as trial continues On Thursday, the second day of the federal trial of Dylann Roof, the 22-year-old white supremacist accused of murdering nine black parishioners during a brutal hate crime, horrific images depicting the bloody aftermath of the Charleston church massacre were shown to the jury. They revealed that seven of the victims had been shot dead at one end of the room, as they attempted to hide underneath a cluster of large round tables. Earlier on Thursday, attorneys for Roof unsuccessfully attempted to force a mistrial. Charleston shooting trial: jury shown graphic images of aftermath South Korean MPs vote to impeach president South Korean MPs voted to impeach President Park Geun-hye, over a corruption and cronyism scandal that has made her the country's most unpopular leader since it became a democracy in the late 1980s. Allegations that Park abused her position to help her friend Choi Soon-sil secure tens of millions of dollars of funding for her foundations from major South Korean companies, and even allowed her to influence policy, provoked a wave of anger across the country. Park's duties will be temporarily transferred to the prime minister while the country's constitutional court decides whether the impeachment vote is valid. If six of the court's nine justices support impeachment, Park will be removed from office and a new presidential election held within 60 days.

In the decimated city, he spoke to the survivors whose homes have been destroyed and families lost, their children are starving.

Her gynecologist, Ralph Anderson, has been using virtual reality in his medical practice to help calm patients before minor procedures and during early-stage, passive labor. The company that created the virtual environment and supplied the headset Anderson uses, AppliedVR, has partnered with Cedars-Sinai Medical Center in Los Angeles for clinical studies.
