The marbled crayfish looks much like any other freshwater crustacean. It has two claws, ten legs, and an attractive blue-brown marbled shell. Yet this six-inch creature, found in streams and lakes around the world, is far more sinister than you might expect. ... There was something very strange about these crayfish. They were all female, and they all laid hundreds of eggs without mating. These eggs, in turn, hatched into hundreds more females -- with each one growing up fully able to reproduce by herself. In 2003, scientists sequenced their DNA and confirmed what many owners already believed to be the case: Each baby crayfish was a clone of its mother, and they were filling Europe's fishtanks at alarming speed. read more
ormer Vice President Joe Biden said Tuesday that if he were one of President Donald Trump's attorneys, he would suggest Trump not consent to a special counsel interview for fear of being caught misleading investigators. "The President has some difficulty with precision," Biden said in an interview with CNN's Chris Cuomo. ... CNN reported last month that special counsel Robert Mueller provided Trump's attorneys with a range of topics for an interview, and that Trump's attorneys are arguing Mueller has not met the threshold for an interview. Trump has said publicly he would be willing to sit for an interview under oath, although The New York Times reported Monday that Trump's attorneys are advising Trump against an interview because of concerns he might be charged with lying to investigators. read more
The U.S. Supreme Court on Monday refused to block a lower court ruling requiring Republican-drawn congressional districts in Pennsylvania to be reworked immediately, boosting Democratic hopes of winning control this year of the U.S. House of Representatives. Justice Samuel Alito denied an emergency application filed by Republicans to stop the immediate reworking of the electoral district boundaries, preserving a ruling by the state's top court that they had unlawfully sought partisan advantage over the Democrats in drawing the maps.
President Donald Trump's war on opioids is beginning to look more like a war on his drug policy office. White House counselor Kellyanne Conway has taken control of the opioids agenda, quietly freezing out drug policy professionals and relying instead on political staff to address a lethal crisis claiming about 175 lives a day. The main response so far has been to call for a border wall and to promise a "just say no" campaign. ... Conway touts her opioids effort as policy-driven, telling Politico recently that her circle of advisers help "formalize and centralize strategy, coordinate policy, scheduling and public awareness" across government agencies. read more
The Philadelphia Eagles' flight from last to first ended up with a Lombardi Trophy. In a record-setting shootout between Nick Foles and Tom Brady, the backup quarterback led a pressure-packed 75-yard drive to the winning touchdown, 11 yards to Zach Etrz with 2:21 to go Sunday night. Then a defense that had been shredded throughout the second half made two final stands to win 41-33. Brandon Graham strip-sacked Brady and Derek Barnett recovered, setting up rookie Jake Elliot's 46-yard field goal for an 8-point lead. Then Brady got his team to midfield before his desperation pass fell to the ground in the end zone.
