The South Georgia Islands might not be permanently populated by humans, but it is an important sanctuary for penguins, seals and other various creatures in the South Atlantic.But a giant iceberg, A68a, could threaten the wildlife on the islands, according to the Government of South Georgia & the South Sandwich Islands.With the assistance of the Royal Air Force, the government has been tracking the iceberg’s movement toward the islands. While the islands do not have a permanent population, they are visited by tourists and others.According to the BBC, A68a was 150 kilometers from South Georgia. The concern is the iceberg could disrupt breeding for penguins on the island.“We are now entering the key part of the year for breeding," Mark Belchier, director of fisheries and environment for the government of South Georgia & the South Sandwich Islands, told BBC News."The nests have been built for gentoo penguins, and eggs will be laid soon. And the first seal pups have been born in the last fortnight," he added.The islands used to be populated on a more permanent basis as a small settlement ran a whaling station.Before air travel, the islands were used by explorers to prepare for treks to Antarctica. Whalers on the island also played a key role rescuing Sir Earnest Shackleton’s crew after his expedition became stranded on Antarctica’s Elephant Island. 1381

The White House on Tuesday said the Justice Department should consider a criminal prosecution of former FBI Director James Comey, claiming he had leaked privileged information to the press and offered false testimony to Congress."It's something they should certainly look at," press secretary Sarah Sanders told reporters when asked whether the administration should prosecute Comey. She acknowledged that it was "not the President's role" to determine which criminal investigations are taken up by the Justice Department.The question arose as Sanders defended Trump's decision to fire Comey earlier this year, a choice Trump's former chief strategist called a mistake this week.Speaking to "60 Minutes" on CBS, Steve Bannon called the Comey decision the worst mistake in "modern political history." 812

The US ambassador to Mexico was not invited to a meeting between senior White House adviser Jared Kushner and Mexican officials, including President Enrique Pe?a Nieto, a US official told CNN.Roberta Jacobson, a career diplomat who has more than 30 years of experience in the region, announced her retirement earlier this month effective in May. Her departure comes at a time when US relations with Mexico have been strained over issues related to trade and migration.Kimberly Breier, who was just nominated to be the new assistant secretary for Western Hemisphere -- a senior State Department position Jacobson previously held -- was with Kushner at the Wednesday meeting.The New York Times first reported that Jacobson was not at the meeting.The timing of the meeting came amid NAFTA negotiations and questions over President Donald Trump's tariff proposal. It also comes shortly after Kushner had his security clearance downgraded because he had not obtained his full clearance.  995

The recommended amount of sleep for adults is six to eight hours a night. Sleeping more than those hours is associated with an increased risk of death and cardiovascular diseases, says a global study published Wednesday in the European Heart Journal.Looking at data from 21 countries, across seven regions, the research team found that people sleeping more than the recommended upper limit of eight hours increased their risk of risk of major cardiovascular events, like stroke or heart failure, as well as death by up to 41%.But a possible reason for this could be that people have underlying conditions causing them to sleep longer, which in turn could raise the risk of cardiovascular disease or mortality, explain the authors of the study.The team, led by Chuangshi Wang, a Ph.D. student at McMaster and Peking Union Medical College in China, also identified a rising risk among daytime nappers."Daytime napping was associated with increased risks of major cardiovascular events and deaths in those with [more than] six hours of nighttime sleep but not in those sleeping [less than] 6 hours a night," Wang said.In those who underslept, "a daytime nap seemed to compensate for the lack of sleep at night and to mitigate the risks," Wang explained.Previous studies into this topic were mainly carried out in North America, Europe and Japan. The new study brings a global picture.But the findings are observational, meaning the cause of this association remains unknown."Even though the findings were very interesting they don't prove cause and effect," said Julie Ward, a senior cardiac nurse at the British Heart Foundation, who was not involved in the study.Having less sleep -- under six hours -- was also shown to increase these risks by 9%, compared with people who slept for the recommended six to eight hours, but this finding was not considered to be statistically significant by the team.In 2014, 35.2% of American adults reported not getting enough sleep with less than seven hours per night, according to the CDC. 2049
