Right now, nearly 2 million people are living with limb loss in the United States. But new technology is bringing hope, with a prosthetic that responds to what a person is thinking. Whether it's picking out socks or picking up LEGO blocks, Mario Gasbarro seems to be doing it all just fine, using what his kids affectionately call his “robot arm.” “They seem to enjoy it more than my old arm,” Gasbarro jokes. At just 34 years old, Gasbarro’s doctors told him the lump that had been growing on his elbow was a malignant tumor. As it grew, his doctors determined amputation was his best option. “I don't need my left arm to be able to love my kids and love my wife and to be there for them, so that was always a priority,” Gasbarro says. Now, he’s living with this prosthesis, which moves based on how he thinks and moves his muscles. “I want to open my hand. I think, ‘OK, open my hand and move the muscles to open my hand,’ and I just need to replicate that muscle movement each time I want to try to open my hand,” Gasbarro says.Dr. David Schnur with Presbyterian/ St. Luke’s Medical Center worked with Gasbarro through the process. “Instead of the patient learning the prosthesis, the prosthesis really learns the patient,” Dr. Schnur describes of the prosthetic arm. Through a process called targeted muscle reinnervation, Dr. Schnur attached the nerves from Gasbarro’s forearm that power the hand to muscles in his elbow. “And then what happens is when Mario thinks about closing his hand, instead of causing a muscle to fire down his forearm, it causes a muscle to fire up in his in his biceps,” Dr. Schnur describes. Those signals are then picked up by his prothesis through pattern recognition. “He contracts the muscles. That makes sense for him to close the hand and the computer on the prostheses picks that up and is then able to convert that specific signal into a hand closed,” Dr. Schnur says. Gasbarro says it's not second nature just yet, but he's getting there with practice.“I’ve never felt limited, or like, I’m not able to do anything,” Gasbarro says. 2084

Saturday marks the "First in the West" nomination race with Democrats in Nevada caucusing at a critical time in the campaign for the remaining Democratic field. While New Hampshire and Iowa gave Sen. Bernie Sanders and Mayor Pete Buttigieg some early momentum, Nevada is the first state that will include a diverse voting base. The Nevada Democratic Party says the Nevada Caucuses is a good litmus test on who could best represent the party and be the Democrats' standard-bearer in 2020. After Iowa, all eyes on the tabulationUnlike most primaries, which are run by state boards of election, caucuses are run by the party. Two weeks ago, the Iowa Democratic Party came under fire for a failed vote tabulation as results took several days to be compiled. The fiasco in Iowa was caused by a glitch in an app, and forced the state party chair to step down. Democrats are hopeful that technology does not fail them again. Nevada Democrats too are going to rely on technology. Precincts will each use an iPad with a Google Drive document used to report real-time numbers back to the party. Precinct chairs will also be asked to call the Democratic Party, and send a picture via text message of the paper tabulation that is signed off by representatives of the viable campaigns. How a caucus worksCaucuses are more akin to community events rather than a typical election. Rather than using a secret ballot, caucus goers will first hear from supporters of the candidates, representatives of the campaigns, or perhaps even from the candidate themselves.Then, those on hand will literally "take sides," and join with other supporters of that campaign. At the precinct, a determination is made of viable and non-viable candidates (generally 15% is the threshold).The supporters of non-viable candidates will then be given 15 minutes to join a viable campaign, or abstain. Once the 15 minutes are up, a tally is taken, and the Nevada Democratic Party releases the number of delegates won by each candidate, which is the most important figure of the day. The party will also release popular vote totals.How are ties brokenIf there is a tie at a caucus site that would affect the number of delegates, the precinct chair will use a deck of cards to break the tie. This is Nevada after all. What is at stake on SaturdayFor Saturday's Nevada Caucuses, a total of 36 national delegates will be up for grabs. The Democrats divvy delegates in a proportional basis, meaning with a wide-open field, it is likely that a candidate will not receive a majority of the delegates on Monday.But with Nevada representing some of the first votes cast in the nomination process, it is important to do well for fundraising and momentum purposes.Where the race standsButtigieg holds a slight lead in delegates over Sanders (23-21). Other candidates with delegates are Sen. Elizabeth Warren (8), Sen. Amy Klobuchar (7) and VP Joe Biden (6). Mayor Michael Bloomberg did not enter the first two nominating contests, and will sit out Saturday’s Nevada Caucuses and the South Carolina Primary on Feb. 29.Although Buttigieg holds the lead in delegates, it is hard to describe him as the frontrunner. Sanders has a plurality of votes, and leads national polling.Polls in recent weeks have consistently shown Sanders in the lead in Nevada. He also has been leading nationally.Real Clear Politics tracks major opinion polls, and an aggregate of polls show that Sanders has seen his share of the vote go from 19% to 27% in the last three weeks. During that time, Bloomberg has seen his numbers more than double, as he has gone from the back of the pack to nearly even with one-time frontrunner Biden for second.But on March 3, the biggest night of the nominating race awaits as more than a dozen states, including Texas and California, hold primaries. These states are already conducting early voting, meaning Wednesday’s debate could be the final opportunity for candidates to make an impression before a crucial Super Tuesday race. 4002

SANTA BARBARA, Calif. (KGTV) -- California State Parks officials worked quickly to protect centuries-old pictographs created inside sandstone caves from being destroyed in the fast-moving Cave Fire.The Chumash art, created by the Chumash Native Americans between 500 to nearly 1000 years ago, was covered by heat resistant tarps, a California State Parks ranger told KSBY.Chumash Painted Cave State Historic Park is one of the few remaining spaces that allow the public open access for viewing the rock art. Efforts to preserve the fragile paintings include prohibiting visitors from using flash photography.The Cave Fire was first reported Monday afternoon and exploded to over 4,000 acres in less than 24 hours, resulting in several evacuations, road closures, and an Air Quality Warning.These historic Chumash caves and their art have outlasted numerous fires, including the deadly Painting Cave Fire in 1990, which scorched over 4,000 acres. 957

Rick Brown walks through Kenai Fjords National Park to a place where climate change's impact is hard to miss. “The changes to us have been bang, bang, bang," Brown says. "Every year it’s a different year."As the years have gone on, the walk to Exit Glacier has become longer because it's melting away. Exit Glacier is one of the smaller glaciers in the park. It's popular with tourists because it's easy to get to. It's a short walk from where they park. Signs mark the path people take to get to the glacier; the dates on the signs range from the early 1900s to 2010. The signs mark where the glacier once was and where it's melted to. "If this doesn’t convince you that things are changing, then there is no use in trying to even convince you," Brown says.Brown owns Adventure 60 North. He takes people on tours and hikes around the glacier. It's a job in glacier tourism that often has him facing questions about climate change. "I tell them what I see, I don’t know the reason why it’s happening," he says. His answer isn't about politics but what's become the reality here."I don’t know if it's humans or nature or naturally caused. I think it’s both, and that's my opinion and I kind of leave it at that," Brown says."I've lived in Alaska for almost 50 years. Anyone who has lived here a long time has seen the weather change," says Doug Capra.Capra is a former park ranger and local historian in tiny Seward, Alaska. “We’ve seen winters come later, springs come earlier,” Capra says. For years, he's documented Alaska's changing climate and Exit Glacier's retreat.“My concern is the denial. I write history and I have great admiration for human ingenuity," Capra says. "Human beings have survived a lot of things. It’s the questions of how we’re going to do it. It’s a question of will."Rick knows some people can't be convinced of the impact climate change is having.“Some people come here with a view that they’ve adopted and they’re not going to change no matter what you tell them," Brown says. "So I don’t try. I’m the old guy out here, I know what I'm seeing."He says winters don't see the snow they did when he first became a guide in Alaska in the '90s. He no longer does snowshoeing and ice hiking tours in the winter because of the lack of snow.“It’s changed our business," he says. "I don’t know if it’s hurt it. I would say we’ve adapted. And as far as I know, the key to surviving here is adapting."Time may be running out for Exit Glacier. “I would say, probably, I don’t know ... there have been guesses of ten, five years?” he says.According to the United States Geological Survey, 68.7% earth's freshwater is kept in ice caps and glaciers, meaning their retreat isn't just an Alaskan concern or one Brown feels should be left for the future. "It's real folks," Brown says. "Change is happening. Regardless of what’s causing it. We need to get prepared to adapt to deal with the change." 2922

ST. LOUIS, Mo. — A St. Louis Man made a gruesome discovery while cleaning out his mother's apartment after she died. Adam Smith says he found a dead baby in her freezer, and it's apparently been there for several years. Smith said he has been living in the apartment and taking care of his mother, who passed away from cancer just a few days ago. He said his mother had kept the box, wrapped up tight, in their freezer for decades and always told him to stay away from it. After she passed away, he decided to open it. "There was a pink blanket, baby blanket, and when I reached down and touched it I could feel a foot," Smith told CNN. I could see the baby's head with hair, hair that was still attached to it, smooth."Police were called to the building early Sunday morning. They call the infant's death "suspicious."Smith told police that he never looked inside the box his mother kept wrapped in the freezer. He always thought it was a frozen wedding cake. Smith says his mother once told him that she lost a child at birth and that family members have told him that his mother had twins at one point, but lost one of the babies at birth. The second twin was allegedly given up for adoption. "Who absolutely keeps their own child in a box for this long and never talks about it and never, I just have so many thoughts and it's just insane," Smith said. Smith said he's distraught thinking about the possibility that the child may have been his sister and what his mother may have done to her. "I have to wait for the autopsy to see if that baby ever took a breath and I cannot help it, to think she might have done something to it. I just can't help it," Smith said. And now that his mother is gone, Smith said he wonders if he'll ever know the truth. "I wanted some kind of closure and I feel like I may never get any closure because my mom's gone," Smith said. The child's death remains under investigation. 1927
