The 2019 Nobel Prize for Medicine has been jointly awarded to William Kaelin Jr., Sir Peter Ratcliffe and Gregg Semenza for their pioneering research into how human cells respond to changing oxygen levels.Announcing the prize at the Karolinska Institute in Stockholm on Monday, the Nobel committee said that the trio's discoveries have paved the way for "promising new strategies to fight anaemia, cancer and many other diseases."The 2019 medicine laureates, the committee added, have identified molecular machinery that regulates the activity of genes in response to varying levels of oxygen.The importance of oxygen has long been established, the committee explained, but how cells adapt to changes in its levels remained unknown.Randall Johnson, prize committee member, described the trio's work as a "textbook discovery.""This is something basic biology students will be learning about when they study, at aged 12 or 13, or younger, biology and learn the fundamental ways cells work. This is a basic aspect of how a cell works and, from that standpoint alone, it's a very exciting thing."The winnersNew York-born Kaelin established his own research laboratory at the Dana-Farber Cancer Institute in Boston and became a full professor at Harvard Medical School in 2002.Semenza, also born in New York, became a full-time professor at Johns Hopkins University in 1999 and since 2003 has been the Director of the Vascular Research Program at the Johns Hopkins Institute for Cell Engineering.Ratcliffe, who was born in Lancashire, England, studied medicine at Cambridge University and established an independent research group at Oxford University, becoming a full professor in 1996. 1694

The convenience stores of Westeros have done good business in recent weeks.Just two weeks after eagle-eyed viewers spotted a rogue takeaway coffee cup in an episode of "Game of Thrones," the show's highly anticipated finale left fans bemused once again.This time, a plastic water bottle made a cameo appearance. Eight years of fighting for the Iron Throne can leave you a bit parched, after all.The bottle debuted in a tense scene as characters discussed the fate of Westeros.Viewers spotted it tucked behind Samwell Tarly's foot, and the show was in hot water on Twitter just moments later.Some viewers said they spied a second water bottle later in the episode.The latest gaffe creates a new headache for HBO, which handled the coffee cup incident deftly, with a lighthearted statement."The latte that appeared in the episode was a mistake. Daenerys had ordered an herbal tea," the company said.The final season of the worldwide phenomenon has received underwhelming reviews and a frosty reception from many longtime fans, who complain the show has been rushed.For some, this latest modern intrusion only made things worse.More than a million people have 1169

The latest standoff between House Democrats and the Trump administration over the testimony of State Department officials has the White House raising fresh questions in a new letter sent Tuesday about why the House is not voting to authorize a formal impeachment inquiry.The White House and its Republican congressional allies have argued that such a vote is necessary, and President Donald Trump's lawyers told House Democrats in the letter that the President and his administration won't cooperate in the ongoing impeachment inquiry, arguing the proceedings amount to an illegitimate effort to overturn the 2016 election results. The lengthy letter all but dares House Speaker Nancy Pelosi to hold a formal vote opening an impeachment inquiry into Trump, though it does not explicitly call on her to do so.But Pelosi has said that Democrats don't need to take a vote and has shown little interest in doing so after she announced last month the House 964
