Celebrities including Amy Schumer and Chelsea Handler have launched an Instagram campaign targeted at Ivanka Trump, urging the US President's daughter to act on the administration's family-separation policy and calling for the resignation of Homeland Security Secretary Kirstjen Nielsen.As part of the campaign, well-known figures followed by Ivanka Trump on Instagram -- including not just Schumer and Handler, but also American fashion entrepreneur Sophie Amoruso and British model Cara Delevingne -- have been posting messages detailing the alleged abuses of children under controversial family separations at the US-Mexico border in an effort to flood her feed.The coordinated messages begin: "Dear Ivanka, you follow me on social media. You said family separation was a 'low point' for you. The low point is for the separated families. You spoke in past tense. This crisis is ongoing."The White House did not respond to a request for comment.The campaign began after Trump broke her silence on family separations on Thursday, saying during an Axios News Shaper conversation that it "was a low point" of her time in the White House."I felt very strongly about that and I am very vehemently against family separation and the separation of parents and children so I would agree with that sentiment. Immigration is incredibly complex as a topic. Illegal immigration is incredibly complicated." 1412

CAPE CANAVERAL, Fla. (AP) — SpaceX's sleek, new crew capsule arrived at the International Space Station on Sunday, acing its second milestone in just over a day.No one was aboard the Dragon capsule launched Saturday on its first test flight, only an instrumented dummy. But that quickly changed once the hatch swung open and the space station astronauts floated inside."A new generation of space flight starts now with the arrival of @SpaceX's Crew Dragon to the @Space_Station," NASA Administrator Jim Bridenstine tweeted. "Congratulations to all for this historic achievement getting us closer to flying American Astronauts on American rockets."This beefed-up, redesigned Dragon is the first American-made, designed-for-crew spacecraft to pull up to the station in eight years. The next one coming up will have its own two-man crew.The space station's three astronauts had front-row seats as the white 27-foot-long (8-meter-long) capsule neatly docked, a little early no less. TV cameras on Dragon as well as the station provided stunning views of one another throughout the rendezvous.Just two hours after the Dragon's grand entrance, the station crew entered to take air samples. The astronauts wore oxygen masks and hoods until getting the all-clear.If the six-day demo goes well, SpaceX could launch two astronauts this summer under NASA's commercial crew program. Both astronauts — Doug Hurley and Bob Behnken — were at SpaceX Mission Control in Southern California, observing all the action. They rushed there from Florida after watching the Dragon rocket into orbit early Saturday from NASA's Kennedy Space Center."Just super excited to see it," Behnken said minutes after the link-up. "Just one more milestone that gets us ready for our flight coming up here."While SpaceX has sent plenty of cargo Dragons to the space station, crew Dragon is a different beast. It docked autonomously under the station astronauts' watchful eyes, instead of relying on the station's robot arm for berthing. The capsule's nose cap was wide open like a dragon's mouth, to expose the docking mechanism.Behnken said that's the way it should work when he and Hurley are on board; they may push a button or two and will have the ability to intervene, if necessary.As part of Sunday's shakedown, the station astronauts sent commands for the Dragon to retreat and then move forward again, before the capsule closed in for good.SpaceX employees at company headquarters in Hawthorne, California, cheered and applauded as crew Dragon pulled up and docked at the orbiting lab, nearly 260 miles (400 kilometers) above the Pacific, north of New Zealand. They burst into applause again, several minutes later, when the Dragon's latches were tightly secured.The capsule's lone passenger for launch — a mannequin wearing a white SpaceX spacesuit — remained strapped into its seat as the station's U.S., Canadian and Russian crew removed supplies and photographed the spotless white interior. The test dummy — or Smarty as SpaceX likes to call it, given all the instrumentation — is named Ripley after the lead character in the science-fiction "Alien" films.Dragon will remain at the space station until Friday, when it undocks and aims for a splashdown in the Atlantic, a couple hundred miles off the Florida coast.Like Ripley, the capsule is rigged with sensors to measure noise, vibration and stresses, and to monitor the life-support, propulsion and other critical systems throughout the flight.SpaceX aims to launch Behnken and Hurley as early as July.Next up, though, should be Boeing, NASA's other commercial crew provider. Boeing is looking to launch its Starliner capsule without a crew as early as April and with a crew possibly in August.NASA is paying the two private companies billion to build and operate the capsules for ferrying astronauts to and from the space station. Astronauts have been stuck riding Russian rockets ever since NASA's space shuttle program ended in 2011. Russian Soyuz seats go for up to million apiece. 4030

CHANDLER, Ariz. - A woman in the East Valley of Arizona was stung by bees more than 200 times and a few fellow runners just happened to be in the right place--and the right time--to help.Usually cooler weather keeps bees away, but with more trees and flowers in bloom after the recent rain, experts say the bees are sticking around."I was taking my dog out for a walk, it's a normal route," said Marisa Brazil.Her daily routine along Paseo Trail in Chandler took a terrifying turn Monday morning."She was starting to flail her arms and I kind of looked at my best friend, Julie, and said, 'she's either having a really good time or something's happening,'" Brazil said.It did not take long for both women to realize something terrible was happening to the runner ahead of them on the trail."She was really screaming, like loud," said Julie Sternberg. The trained lifeguard ran to help while Brazil called 911."I tried to run up the other side and then some bees came at me," Sternberg said.Sternberg was stung on her head as the bees forced her back. She then saw two other strangers battling their way forward."They kept retreating. So at that point once I figured out there was bees, I figured out that's why. I saw one guy kept moving back," said Sternberg. "She was still screaming the whole entire time, so it was pretty scary," said Brazil.First responders eventually took over. The woman who was stung posted to Facebook from her hospital bed, thanking the strangers who tried to help. The woman who was stung is expected to recover. Her family said she was released from the hospital Monday afternoon.Now Brazil is warning others to be on alert."Just letting people in my community know that there is something going on there," Brazil said.A technician at The BEEHIVE Bee and Wasp Removal in Gilbert said if you find yourself surrounded by a swarm, swatting is the worst thing to do because that only agitates the bees. He says the best thing to do in a similar situation is remain calm, cover your face and nose, and run as fast as you can away from the area. 2126

CHICAGO, Ill. – Approximately 7 million Americans live with the movement disorder known as essential tremor. Another 1 million have Parkinson’s. But a new incision-less treatment that focuses ultrasound beams onto the brain is providing new hope to patients who suffer from movement disorders.Gary Sindelar, 75, began experiencing tremors in his hands and legs while in his early 60s.“They were kind of scary because I didn't know what it was. I didn't know why my hands were jumping and my fingers were moving, and I didn't want them to,” said Sindelar.The tremors made everyday activities, like eating, increasingly difficult.“I would cut, and I would cut and all of a sudden my hand would jump in and would throw the food right off the plate,” he said. Essential tremor is a neurological disorder that causes involuntary and rhythmic shaking. It can affect almost any part of the body, but the trembling most often occurs in hands, making simple tasks, like drinking water from a glass or tying shoelaces, difficult.“I didn't like you have to explain to my grandchildren all the time. ‘What's the matter with grandpa?’”After years of living with the condition, Sindelar’s doctors at Rush University Medical Center in Chicago determined he was a candidate for a new, non-surgical procedure.“There are some patients who are old or older and the surgical risk is high,” said Dr. Sepehr Sani, associate professor of neurosurgery at Rush University Medical Center. “And so, they choose to accept and a very poor quality of life with tremors.”Neurosurgeons used a mouse and a computer instead of a scalpel. More than 1,000 ultrasound waves coalesce to burn lesions in the brain and stop the tremors. The neurosurgeon is guided by real-time hi-resolution MR imaging.“We can actually see with our own eyes what's happening inside the brain as this is occurring and that allows us to control exactly where and how much of the lesion we make,” said Sani.The innovative treatment is now covered by Medicare in all 50 states.Sani says the new incision-less outpatient procedure could be a revolution in treatment.“Now the patients literally walk into an MRI machine and get the treatment and they can leave within about an hour, hour and a half.”Six weeks after undergoing the procedure, Sindelar’s left hand and leg are more still than they’ve been in more than a decade.“This side, I can hold it steady,” he said.Regaining that steadiness, he says has been life-altering.“I would have said to you that I think I probably had 10 years of life,” said Sindelar. “And I could have 50 years left now.”It’s an emotional reality that could provide hope to countless others. 2667

CHATTANOOGA, Tenn. – Spy, prisoner of war, patriot – at one time or another, all those words described Dr. Mary Walker, a practicing surgeon for the Union Army during the Civil War.“She was a woman ahead of her time,” said Keith Hardison, director of the Charles H. Coolidge National Medal of Honor Heritage Center in Chattanooga, Tennessee.Now, though, Dr. Walker’s time has come. She is the focus of a new special exhibit at the center.“Dr. Walker wanted to go where the fighting was bloodiest,” said exhibit curator Molly Randolph. “She tried multiple times to join up and was denied.”Yet, she persisted and volunteered her medical skills to Union commanders during the Civil War. They put her to work – for no pay – on the front lines.That’s when her career as a spy began.“She used that cover of going into the countryside and providing medical care to do some espionage,” Randolph said.Eventually, the Confederate Army captured her and held her as a prisoner of war for four months, where she became well-known for wearing her trademark pants.“She was rather notorious,” Randolph said. “She was written up in the Confederate papers. Everyone thought this, you know, doctor - a female doctor who wore pants! - was a thing to poke fun at a little bit.”Suffering severe malnourishment at the Confederacy’s notorious “Castle Thunder” prison, Dr. Walker was eventually released in a prisoner exchange.“She was actually exchanged for a Confederate doctor, which she loved. She loved that she was worth so much to the federal forces,” Randolph said.Dr. Walker returned to the front lines to provide medical care for the Union Army. When the war ended, President Andrew Johnson awarded her the Medal of Honor.She became the first woman to ever receive it and – so far – remains the only one.“I’m surprised there’s only been one,” said Tom Jones, who was visiting the Medal of Honor Heritage Center from Illinois. “I know there’s not been a lot of women in combat, but they’ve been serving since the Civil War, obviously.”In 1917, the military instituted new rules for awarding the Medal of Honor and stripped Dr. Walker of hers because, technically, she had not been formally enlisted – though she had repeatedly tried to sign up.She died two years later, in 1919.“She refused to return it and continued to wear it,” Randolph said. “So, it was obviously something that was incredibly important to her.”Six decades later, a military board and President Jimmy Carter would once again reinstate her medal.“She was willing to challenge things that were unfair or that were convention, but were holding people back,” Hardison said.Dr. Walker was a lifelong suffragist. Her exhibit coincides with this summer’s 100th anniversary of the 19thAmendment, which granted women the right to vote in the U.S. It’s an amendment she didn’t live long enough to see become a reality.Her exhibit’s curators hope she will remind others of how to face life’s challenges.“She really shows us how to respond with poise, with gusto, with dignity,” Randolph said, “and I think Dr. Walker is just a wonderful example.”For more information on the exhibit about Dr. Mary Walker, click here. 3168
