First gene-editing in human body attempt

First gene-editing in human body attempt

Health
Gene-editing has been attempted on cells inside a patient, in a world first by doctors in California.Brian Madeux, 44 from Arizona, was given the experimental treatment to try to correct a defect in his DNA that causes Hunter's syndrome. Mr Madeux says he was prepared to take part in the trial as he is "in pain every second of the day".It is too soon to know whether or not the gene-editing has worked in Mr Madeux's case. Hunter's syndrome is rare. Patients are born without the genetic instructions for an enzyme that breaks down long sugary molecules called mucopolysaccharides.Instead, they build up in the body and damage the brain and other organs. Severe cases are often fatal. "I actually thought I wouldn't live past my early 20s," said Mr Madeux.Patients need regular enzyme replacement t...
NASA readies for another JPSS-1 launch attempt

NASA readies for another JPSS-1 launch attempt

Science
Nov. 14 (UPI) -- NASA is preparing for another launch attempt of JPSS-1, NOAA's latest weather satellite.The Joint Polar Satellite System-1 was supposed to be carried into orbit in the wee hours of Tuesday morning, but the United Launch Alliance Delta II rocket's blastoff was delayed after a vehicle alarm sounded just prior to countdown.The launch has since been rescheduled for Wednesday morning at 4:47 a.m. ET. The rocket will liftoff from Space Launch Complex-2 at California's Vandenberg Air Force Base.JPSS-1 is the first of four next-generation weather satellites to be launched on behalf of the National Ocean and Atmospheric Administration.The polar-orbiting satellite will cross the equator 14 times everyday and complete two scans of the entirety of Earth every 24 hours. Its instruments...
Supersonic car in test run for record attempt

Supersonic car in test run for record attempt

Technology
A supersonic car combining the technology of a fighter jet, F1 car and spacecraft has been tested in public ahead of a land speed world record attempt.Bloodhound SSC has been built over nine years by a team of Bristol-based engineers from aeronautical and automotive backgrounds.After weeks of trials, the car was put through its paces at Newquay Airport in Cornwall.Video:Jet-propelled car in test runThe two runway trials came after a series of tests to check the car's steering, brakes, suspension and data systems, as well as the efficiency of the intake feeding air to the EJ200 jet engine, sourced from a Eurofighter Typhoon.The landmark moment in the high-profile project came 20 years after the current land speed world record was set on 15 October, 1997.Many of those who set that record are...
MIT engineers attempt to predict extreme events

MIT engineers attempt to predict extreme events

Science
Sept. 22 (UPI) -- Can a new mathematical framework pinpoint the warning signs before an extreme event? A group of engineers at the Massachusetts Institute of Technology think so.Researchers at MIT have developed a set of mathematical equations that can be used to identify patterns that precede extreme events, like a rogue wave or instability inside a gas turbine."Currently there is no method to explain when these extreme events occur," Themistoklis Sapsis, an associate professor of mechanical and ocean engineering at MIT, said in a news release. "We have applied this framework to turbulent fluid flows, which are the Holy Grail of extreme events. They're encountered in climate dynamics in the form of extreme rainfall, in engineering fluid flows such as stresses around an airfoil, and acoust...
Turkey to mark anniversary of coup attempt

Turkey to mark anniversary of coup attempt

World
Media playback is unsupported on your deviceEvents will be held in Turkey later to mark the first anniversary of a failed coup in which at least 260 people died and 2,196 were wounded.A faction of the army tried to seize power from President Recep Tayyip Erdogan but the attempt collapsed.Since the coup, the government has dismissed more than 150,000 employees from state institutions in a purge that continued until the anniversary's eve.It has rejected criticism, saying it had to root out coup supporters.But the purge, as well as a wave of 50,000 arrests alongside it, have galvanised opposition. The human impact of Turkey's purgesThe officers who cannot go homeCritics say Mr Erdogan is using the purges to stifle political dissent, and last week hundreds of thousands of people gathered in Is...
