LOS ANGELES， March 29 (Xinhua) -- A U.S. federal judge in Hawaii on Wednesday extended his previous nationwide order blocking the implementation of President Donald Trump's revised travel ban while the lawsuit continues.


U.S. District Judge Derrick Watson's original order halting the travel ban was issued on March 15， hours before the ban was set to go into effect， in the form of a nationwide temporary restraining order.


Court papers show that Watson granted a motion on Wednesday to turn his temporary restraining order into a preliminary injunction， extending his order against the ban while the case moves forward.


The move sets the stage for the Department of Justice to appeal to the 9th Circuit Court of Appeals， which is the same court that upheld a national halt to Trump's first travel ban last month after a Seattle federal judge ruled against it.


Hawaii has become the first state in the United States to file a lawsuit against Trump's revised travel ban. Judge Watson blocked provisions of the March 6 executive order of Trump that would have frozen the refugee program for 120 days and stopped citizens of six Muslim countries from entering the United States.


The revised travel ban will bar entry of citizens of Iran， Libya， Syria， Somalia， Sudan and Yemen for 90 days.


The new order lowered the named nations from seven to six， among other changes. Iraq， which was included in the first ban， has been taken off the list.


The state of Hawaii sued to stop the travel ban， arguing the president's policy violates the Constitution and the travel ban would harm its economy because of the loss of tourism and the ability to recruit international students.


Trump reacted to Watson's March 15 restraining order by calling the ruling "an unprecedented judicial overreach"， pledging to take the legal fight all the way to the Supreme Court.


WASHINGTON Nike Air Max 98 UK , Nov. 1 (Xinhua) -- Long-duration spaceflight may lead to "significant changes" in the structure of astronauts' brains, a U.S. study said Wednesday.


Many astronauts have been known to have experienced altered vision and increased pressure inside their heads during spaceflight aboard the International Space Station, a phenomenon known as visual impairment and intracranial pressure syndrome Nike Air Max 2018 UK , or VIIP syndrome for short.


Given safety concerns and the potential impact to human exploration goals, the U.S. space agency NASA has made determining the cause of VIIP syndrome and how to resolve its effects a top priority.


"We know these long-duration flights take a big toll on the astronauts and cosmonauts," Donna Roberts Nike Air Max 97 Ultra 17 UK , a neuroradiologist at the Medical University of South Carolina, who led the study, said in a statement.


"However Nike Air Max 97 Off White UK , we don't know if the adverse effects on the body continue to progress or if they stabilize after some time in space," Roberts said. "These are the questions that we are interested in addressing, especially what happens to the human brain and brain function?"


In the new study Nike Air Max 97 Gold UK , Roberts and colleagues compared the brain images of 18 astronauts who had been in space for short periods of time aboard the U.S. Space Shuttle to those of 16 astronauts who had been in space for longer periods of time, typically three months, aboard the International Space Station.


They evaluated the cerebrospinal fluid (CSF) spaces at the top of the brain and CSF-filled structures Nike Air Max 97 Ultra UK , called ventricles, located at the center of the brain.
