From $300 to Her Name to NASA’s Head Mars Engineer
It takes a lot to get someone with a few dollars in their pocket to believe that one day they will make big differences for an entire country. That was the case for Diana Trujillo. When she was a child in the 1980s, her world was a town in Columbia where girls were expected to grow to women taking care of households, having children and being wives. Science, much less engineering, were not necessarily the fields little girls in Columbia were expected to go into as they went through school and grew up.
However, for Diana, her world was expanded greatly when her father thought it was a good idea for the girl to spend time with her aunt in Florida, and it would give her a chance to learn another language by immersion. That jump allowed Diana to see other possibilities for her future.
At the age of 17 and with $300 of pocket money, she bundled a suitcase and visa to enter the U.S. and stay with her relative for a bit. And from that opportunity Diana shuffled and leverage housekeeping cleaning jobs to classes at Miami Dade College. That then allowed her both to learn English and something more, take classes in aerospace engineering. While not the typical classes one expects to have in a bachelor level college, Florida had a ton of aerospace engineering offerings practically being the capital of space exploration with Cape Canaveral up-state from Miami itself.
Challenges were bread and butter early on for Diana. At times, she was taking well over 5 bus connections daily to get to and from her school and her aunt’s home. Yet every bathroom she cleaned was one day closer to another class, another requirement, another degree step in getting her qualifications in engineer. The difference was perspective; compared to her otherwise expected path in Columbia everything she did in Florida was stepping-stone to a better opportunity in her mind. It paid for food, a place to sleep, her bus fare and her books. And then, being in the right place at the right time, one of her professors connected Diana to an astronaut. That experienced pushed her further to chase after a slot in the NASA Academy.
The NASA Academy served as a recruitment funnel for potential new hires showing exceptional aptitude in core engineering skills that the agency was always looking for. Given the push for the space shuttle and alternative space vehicles, NASA was on the hunt for new talent where it could be found. Diana ended up getting accepted, and she excelled. She performed to the top of her class and became one of only a duo offered hiring positions in NASA fulltime. She had already come a long way from that little girl in Columbia when she received her employee badge.
Like many of the engineers at NASA, Diana worked on multiple projects and cut her teeth on some of the newest ideas being tried. Robotics ended up being a big element in that experience-build by the mid-2000s. That experience also allowed Diana to complete a bachelors degree in Robotics by the second half of the 2000s, courtesy of her connections and NASA’s employment. By the next decade, Diana had skyrocketed to project lead on Curiosity Rover on Mars in 2014, and she made history again as the lead on the Perseverance Rover in 2021 also on Mars. And, no surprise, Diana also became NASA’s Hispanic voice, providing technical commentary on the Perseverance project to the entire Latin world. In gratitude, she was awarded the Policarpa Salavarrieta, Columbia’s order of merit award.
From cleaning bathrooms to managing the first human-built robot an entire planet away, Diana clearly proved how she could change our world and another one too. Sources
Google is making strides in the world of artificial intelligence (AI), particularly with a system that could revolutionize how doctors diagnose diseases. Imagine a world where your cough could be the key to an early diagnosis of illnesses like COVID-19 or tuberculosis. Google’s AI, known as Health Acoustic Representations (HeAR), is a step towards this future.
HeAR has been trained on millions of audio clips that capture a wide range of human sounds, including coughs. This massive collection of sounds is what sets HeAR apart. It allows the AI to learn and identify the unique characteristics of different respiratory diseases.
Traditionally, doctors diagnose diseases based on symptoms, tests, and sometimes, the sounds of a patient’s cough or breathing. However, this method can be subjective and limited by the doctor’s experience. Google’s AI system aims to make this process more objective and accurate by using machine learning. This means that the AI can improve its diagnostic abilities over time, learning from the vast array of sounds it has been trained on.
Dr. Yael Bensoussan, a laryngologist at the University of South Florida, points out that while supervised learning in medicine has its benefits, such as clinical validation, it’s often restricted by the availability of annotated data sets. HeAR’s approach overcomes this by learning from a vast and diverse set of sounds, not limited to annotated or labeled data.
In the near future, this AI could assist physicians in diagnosing diseases more quickly and accurately. It might even help in assessing lung function, providing a valuable tool in managing and treating respiratory illnesses.
The development of HeAR by Google represents an exciting advancement in the use of AI in medicine. It showcases the potential of machine learning to enhance diagnostic processes and improve patient outcomes, making it a fascinating development in the field of medical technology.
In Dallas, there’s a man named Ron Post who made a huge difference in the lives of millions of people needing health care. His journey began 45 years ago when he saw something on the news that changed his life.
Post and his wife were watching a report about Cambodian refugees fleeing to Thailand from the Khmer Rouge’s “Killing Fields,” where about 2 million people died due to starvation, overwork, and execution. One image struck him hard: the frail body of a teenage girl, which reminded him of his own daughter. This moment touched his heart deeply, and he felt a strong call to take action.
“I believe God put it in my heart that I was to raise up a medical team, and I was to help them,” Post said. And that’s exactly what he did. Although he was a Dallas-based business owner with no experience in medicine, Post’s determination was unstoppable. Within just two weeks, he managed to raise $250,000 and gathered a group of 28 volunteers. Together, they traveled to Thailand to offer their assistance at a refugee camp.
That act of kindness and determination was the start of something much bigger. The organization he founded, Medical Teams International, has grown significantly over the years. Today, it helps around 3 million refugees across eight different camps, providing them with the medical care they desperately need.
But Medical Teams International didn’t stop there. They expanded their services and now operate 13 mobile dental clinics, reaching about 25,000 people every year. These clinics travel to different locations, offering dental care to those who otherwise might not have access to it.
Ron Post’s story shows how one person’s compassion and drive can lead to extraordinary achievements. From his initial heartfelt response to a crisis far from home, he built an organization that continues to provide vital health services to millions of people. Medical Teams International stands as a testament to what can be achieved when someone decides to make a positive change in the world.
In Paradise, California, a community came together to find a much-loved cat named Dundee, who had survived the devastating 2018 Camp Fire. Dundee’s adventure began when his owner, Suise Heffernan, took him to the vet. After the appointment, she stopped to get pet food, locking her truck with Dundee inside. But when she returned, the truck and Dundee were gone.
Surveillance footage from a nearby store showed someone breaking into the vehicle and driving off with Dundee still inside. Heffernan was especially worried because Dundee has a thyroid condition and needed his medication.
The whole community of Paradise stepped up to help find Dundee. After four long days, their efforts paid off, and Dundee was found. Heffernan had adopted Dundee in 2018, just before the Camp Fire. She lost her home, a barn, and hundreds of acres of timber in the fire. Despite being displaced, Dundee transformed from a feral cat into a warm and cuddly companion.
One community member pleaded, “Just return the cat! Trucks can be replaced, and anyone living on the ridge has lost so much already.” Heffernan shared her agony over not knowing Dundee’s whereabouts, a feeling she knew all too well from losing another cat in the Camp Fire.
Heffernan and her friends, along with independent volunteers, continued their search. Finally, on Saturday, they received a call from someone who had Dundee. A group drove to Chico that evening, where Heffernan was reunited with Dundee, who started purring immediately.
Heffernan expressed her gratitude for the community’s support: “There’s something about the people – they just come together and they are there for you. I just can’t even imagine the hours that people that I’ll never meet put in on his behalf. It is so appreciated.”
This heartwarming story showcases the power of community and the unbreakable bond between humans and their pets.
In a remarkable display of veterinary ingenuity, a grasshopper at a Texas zoo was fitted with a miniature “neck brace” after experiencing a unique health issue. The grasshopper, a stick-like breed known as a Peruvian jumping stick, recently underwent a common process for insects: molting. At around six months old, these grasshoppers shed their exoskeleton, allowing for growth. However, this particular grasshopper faced a challenge after molting.
According to a recent zoo blog post, the grasshopper had a weakened area around part of its body resembling a “neck” due to a crease in its thoracic region. This crease caused its head to flop backward when climbing upwards, as these grasshoppers spend most of their time in tree branches.
To address this issue, zookeepers developed a miniature neck brace to temporarily support the insect’s neck in a neutral position while its exoskeleton hardened. The brace was created using a sterile Q-tip shaft and microspore tape to secure it. This innovative solution allowed the grasshopper to continue its normal activities without further injury.
The zoo emphasized the importance of providing exceptional care to all its animals, regardless of their size. “Whether it’s a mammal, reptile, bird, or even insect, all of our animals receive extraordinary care from our veterinary team, no matter how big or small it may be,” the zoo stated.
This story highlights the dedication of zookeepers and veterinarians to the well-being of all creatures in their care and showcases the creative approaches they take to ensure the health and safety of even the smallest residents.
In a story that sounds like it’s straight out of a movie, a dog named Ullr, who had been missing for almost a year, was finally spotted alive and well. Ullr, a mix of Border Collie and Rottweiler, had been living in the wild all by himself after surviving an avalanche. For Jacob Dalbey, Ullr’s owner, this news was the light at the end of a very long and dark tunnel.
Jacob Dalbey’s world turned upside down on March 17, when he was caught in an avalanche near Chair Mountain while skiing with friends. The terrifying incident left Jacob seriously injured and hospitalized, and tragically, one of his friends did not survive. Amidst the chaos, Ullr, who was with them, ran away from the avalanche site. Rescue teams later found dog tracks leading away from the debris, sparking hope that Ullr had survived.
For 341 days, Jacob never gave up hope of finding his beloved pet. He set up trail cameras and left food in various locations, hoping to lure Ullr into view. And then, on a day that seemed like any other, the unimaginable happened. Ullr was captured on a trail camera not once, but two days in a row. “After 341 days, 11 months to the day…it has happened,” Jacob shared on his GoFundMe page, a platform where he had been updating supporters and raising funds to aid in the search for Ullr.
The joy and relief in Jacob’s message were palpable as he thanked his friends and supporters for their unwavering belief and support. “Knowing you believe in us really means a lot,” he wrote, acknowledging the tough journey and the difference their support made.
Jacob’s next steps are focused on bringing Ullr safely back home. In the meantime, he has asked for the community’s help in keeping an eye out for any signs of Ullr, including pawprints, barking, or sightings.
Jacob’s harrowing experience during the avalanche, where he was buried under the snow for over three hours with a broken hand and frostbitten fingers, adds a layer of awe to Ullr’s survival story. Jacob’s determination to dig himself out and survive mirrored Ullr’s own fight for survival in the wild.
