WASHINGTON (AP) Â— El subdirector del FBI Andrew McCabe, quien fuera un blanco frecuente de crÃticas por parte del presidente Donald Trump, renunciÃ³ abruptamente el lunes antes de su jubilaciÃ³n ya cercana.
McCabe, veterano de 22 aÃ±os en el FBI, fue criticado pÃºblicamente repetidas veces el aÃ±o pasado por Trump, quien lo ha acusado de parcialidad por las conexiones polÃticas de su esposa y por una investigaciÃ³n del FBI de la cual no surgiÃ³ ningÃºn cargo penal contra Hillary Clinton.
McCabe, que desempeÃ±Ã³ varios puestos de liderazgo y estuvo muy involucrado en investigaciones de crÃmenes importantes _incluido el atentado en el MaratÃ³n de Boston de 2013_, cumplirÃa en cuestiÃ³n de semanas los requisitos para jubilarse. El personal del FBI se enterÃ³ el lunes que McCabe dejaba el segundo cargo mÃ¡s importante de la agencia de forma inmediata, segÃºn personas familiarizadas con la situaciÃ³n que pidieron permanecer anÃ³nimas debido a que no podÃan hablar pÃºblicamente sobre una decisiÃ³n interna relativa al personal.
El tercer funcionario en rango del FBI, David Bowdich, fue nombrado subdirector interino.
Se tiene previsto que McCabe se retire con todos los beneficios de la jubilaciÃ³n.
Su salida se da en el marco de los cambios implementados por el director del FBI Christopher Wray en su equipo de liderazgo. Otros dos funcionarios importantes fueron remplazados la semana pasada. Tales cambios no son inusuales cuando un nuevo director toma las riendas de la agencia, pero son notorios debido a la presiÃ³n de Trump sobre Wray para que despidiera a los funcionarios que eran cercanos al ex director James Comey.
En un mensaje el lunes a los empleados de la agencia, Wray les dijo que McCabe se retirarÃ¡ el 18 de marzo y rechazÃ³ que la medida se deba a presiÃ³n polÃtica.

Almost every major U.S. city has seen years of decline in bus ridership, but Seattle has been the exception in recent years. Between 2010 and 2014, Seattle experienced the biggest jump of any major U.S. city. At its peak in 2015, around 78,000 people, or about one in five Seattle workers, rode the bus to work.
That trend has cooled slightly since then, but Seattle continues to see increased overall transit ridership, bucking the national trend of decline. In 2016, Seattle saw transit ridership increase by 4.1 percent—only Houston and Milwaukee saw even half that increase in the same year.

WASHINGTON — A paralyzed man shared a handshake with President Barack Obama on Thursday by using a mind-controlled robotic arm that, in a first for medical research, is helping to restore his sense of touch.
Obama fist-bumped Nathan Copeland’s robotic hand, and tiny chips implanted in Copeland’s brain let him use his thoughts to move the Star Trek-looking metal arm attached to his wheelchair — and also let him feel subtle pressure in his own fingers when the artificial ones were touched.
He had “pretty impressive precision,” Obama said. “When I’m moving the hand, it is also sending signals to Nathan so he is feeling me touching or moving his arm.”
The president congratulated the University of Pittsburgh researchers who are developing the technology, saying, “what a story.”
The research is part of a quest to make artificial limbs that can feel. On Thursday, the Pittsburgh team reported important early findings: When they blindfolded Copeland, he could correctly identify which robotic finger they touched 84 percent of the time.
“The majority of them, it felt like a pressure or a tingling” in his own corresponding finger, said Copeland, 30, of Dunbar, Pennsylvania, who was left paralyzed after a car accident. When a researcher touched two fingers at the same time, “I just laughed and I said, ‘Are you trying to be tricky or something?”
Preparing to show the president how the cutting-edge research worked, Copeland said he was “circling between excited and nervous every half-hour.”
Harnessing brain waves to power prosthetics is a hot field, with a goal of giving the disabled more independence and improving artificial limbs for amputees as well. Headlines in recent years have reported experiments that let paralyzed people move a robotic arm to touch a loved one or take a drink simply by imagining the motion. Their thoughts activate brain implants that relay electrical signals needed to command movement. The signals are transmitted through a computer to the robotic limb.
What’s new is recreating sensation using this brain-controlled technology. After all, proper motion depends on more than muscle movement. Reach for something and that sense of touch helps you naturally grasp with just enough force to hang on while not either dropping something or crushing it.
“It’s not only that emotional connection we get,” said Robert Gaunt, a Pittsburgh assistant professor of rehabilitation who led the new study. “People have an incredibly difficult time interacting with objects, picking objects up, manipulating them, doing fairly basic things with the hand if they don’t have a very basic sense of touch.”
Step one is placing sensors in prosthetics. The next hurdle is how to allow feedback to and from those sensors. For amputees, some scientists are attempting to wire nerves left in the remaining part of the person’s natural limb directly to the robotic arm.
That’s not possible if a spinal cord injury has interrupted the messages that normally flash between the hand and the brain. But previous monkey research had suggested brain implants could bridge that gap. So surgeons at the University of Pittsburgh Medical Center implanted electrodes in the part of Copeland’s brain that controls what his hands feel.
Electrically stimulating those cells worked even though the car wreck that left Copeland mostly paralyzed happened over a decade ago, Gaunt noted.
“This shows you can get natural sensation” through the brain implant, added Pittsburgh neurobiologist Andrew Schwartz.
Thursday’s report in Science Translational Medicine details the first six months of experiments after Copeland received the brain implants in March 2015. The ongoing research is becoming more sophisticated, as he picks up objects while the electrodes stimulate different amounts of force, Copeland said in a phone interview.
While the work is in just one patient, it’s a step toward creating touch capability, said Richard Andersen, a neuroscientist at the California Institute of Technology whose team also studies mind-controlled prosthetics and is about to begin a similar experiment.
“It still needs to be determined if this tactile feedback will improve performance” in using the robotic arm, Andersen cautioned.
Copeland doesn’t get to take the robotic arm home but is proud of helping to advance the science.
“Technically when it’s over, I will have netted nothing except having done some cool stuff with some cool people,” Copeland said. “It’s cheesy, but Luke Skywalker loses his hand and then basically the next day he’s got a robot one and it’s working fine. We have to get to that point, and to do that, someone has to start it.”
