3D-printed silicone heart beats like the real thing

LinkedIn

Advanced 3D printing and manufacturing techniques that can produce soft machines could save a lot of lives in the future. They could be used to make not just soft robots for search and rescue, but also temporary organs for people on the transplant waiting list, like the artificial heart created and tested by a team of researchers from ETH Zurich. The researchers have developed a silicone heart that beats like the real organ does using a 3D-printing, lost-wax casting technique.

In the future, it could be used as an temporary heart instead of the blood pumps hospitals use today for patients waiting for a heart transplant. Since it’s a single solid silicone structure, it doesn’t have the usual disadvantages associated with typical pumps’ metallic and plastic mechanisms, which are susceptible to complications. That’s why when the team set out to create an artificial heart, they made it their goal to develop one that “is roughly the same size as the patient’s own one and which imitates the human heart as closely as possible in form and function.”

FAA Certifies UPS to Operate Nation’s First Drone-Delivery Airline

LinkedIn

UPS recently announced that it is the first to receive the official nod from the Federal Aviation Administration (FAA) to operate a full “drone airline,” which will allow it to expand its current small drone delivery service pilots into a country-wide network.

In its announcement of the news, UPS said that it will start by building out its drone delivery solutions specific to hospital campuses nationwide in the U.S., and then to other industries outside of healthcare.

UPS racks up a number of firsts as a result of this milestone, thanks to how closely it has been working with the FAA throughout its development and testing process for drone deliveries. As soon as it was awarded the certification, it did a delivery for WakeMed hospital in Raleigh, N.C. using a Matternet drone, and it also became the first commercial operator to perform a drone delivery for an actual paying customer outside of line of sight thanks to an exemption it received from the government.

This certification, officially titled FAA’s “Part 135 Standard certification,” offers far-reaching and broad license to companies who attain it — much more freedom than any commercial drone operation has had previously in the U.S.

Obviously, it’s a huge win for UPS Flight Forward, which is the dedicated UPS subsidiary the company announced it had formed back in July to focus entirely on building out the company’s drone delivery business. But there’s still a lot left to do before you can expect UPS drones to be a regular fixture, or even at all visible in the lives of the average American.

Two female astronauts make history. How to watch NASA’s first all-female spacewalk

LinkedIn

Men have floated out the hatch on all 420 spacewalks conducted over the past half-century. That changed recently with spacewalk No. 421.

NASA astronauts Christina Koch and Jessica Meir ventured outside the International Space Station recently and spevt over five hours replacing a broken battery charger, or BCDU. NASA’s livestream of the historic spacewalk features astronaut Tracy Caldwell Dyson as one of the female narrators.

The units have previously been replaced using a robotic arm, but the newly failed unit is too far away for it to reach.

The units regulate how much energy flows from the station’s massive solar panels to battery units, which are used to provide power during nighttime passes around Earth. Three previous spacewalks had been planned to replace lithium-ion batteries, but those will be rescheduled until the latest BCDU issue is resolved.

The hardware failure does present some concern, especially since another BCDU was replaced in April and there are only four more backups on the station. In total, there are 24 operational BCDUs.

The battery charger failed after Koch and a male crewmate installed new batteries outside the space station last week. NASA put the remaining battery replacements on hold to fix the problem and moved up the women’s planned spacewalk by three days.

All four men aboard the ISS remained inside during the spacewalk.

The spacewalk is Koch’s fourth and Meir’s first.

Not Only Does This New Clothing Charge Your Phone, It Can Protect You From Viruses and Bacteria

LinkedIn

A new addition to your wardrobe may soon help you turn on the lights and music—all while also keeping you dry, clean, and safe from the latest virus that’s going around.

That’s because Purdue University researchers have developed a new fabric innovation that allows wearers to control electronic devices through their clothing.

Purdue University researchers have developed a new fabric innovation that allows wearers to control electronic devices through clothing.

“It is the first time there is a technique capable to transform any existing cloth item or textile into a self-powered e-textile containing sensors, music players or simple illumination displays using simple embroidery without the need for expensive fabrication processes requiring complex steps or expensive equipment,” said Ramses Martinez, an assistant professor in the School of Industrial Engineering and in the Weldon School of Biomedical Engineering in Purdue’s College of Engineering.

The technology is featured in the July 25 edition of Advanced Functional Materials.

“For the first time, it is possible to fabricate textiles that can protect you from rain, stains, and bacteria while they harvest the energy of the user to power textile-based electronics,” Martinez said. “These self-powered e-textiles also constitute an important advancement in the development of wearable machine-human interfaces, which now can be washed many times in a conventional washing machine without apparent degradation.”

Martinez said the Purdue waterproof, breathable and antibacterial self-powered clothing is based on omniphobic triboelectric nanogenerators (RF-TENGs) – which use simple embroidery and fluorinated molecules to embed small electronic components and turn a piece of clothing into a mechanism for powering devices. The Purdue team says the RF-TENG technology is like having a wearable remote control that also keeps odors, rain, stains and bacteria away from the user.

“While fashion has evolved significantly during the last centuries and has easily adopted recently developed high-performance materials, there are very few examples of clothes on the market that interact with the user,” Martinez said. “Having an interface with a machine that we are constantly wearing sounds like the most convenient approach for a seamless communication with machines and the Internet of Things.”

The technology is being patented through the Purdue Research Foundation Office of Technology Commercialization. The researchers are looking for partners to test and commercialize their technology.

Luis “Danny” Bathen of HENAAC: Becoming a Successful Engineer

LinkedIn
Luis "Danny" Bathen headshot

Being an engineer is like being that curious cat. The curious cat knows his or her curiosity may be the end of him or her, but he or she still needs to know how something works.

Without knowing how something works, we may not be able fix it, improve it, or simply innovate a new solution that makes that thing we think is cool obsolete.

Engineers built irrigation systems, engineers built castles, engineers got man to space, engineers built the world-wide web. Engineers are the reason we can see our loved ones across the sea in real time.

Engineers are the reason we can take selfies on a plane—flying across the sea, sharing them with millions of people while sipping our favorite drink thousands of feet up in the sky.

I became an engineer because I am a curious cat—I need to know how something works. I need to know how to build things from scratch. I need to know how to build more efficient things that will make my life and the life of people I care for easier. Being an engineer is rewarding, and also demanding.

It requires a lot of hard work. The cliché of “hard work pays” is indeed true, but to be a good engineer, you need to not only “work hard” but also “work smart.” Working smarter and more efficiently will help you complete tasks much faster. If I can write a computer program to automate a task that will help me work faster, I will. If I can build an Artificial Intelligence system that can automate most of my tasks, it will free my time to do more pressing matters. Artificial Intelligence is a hot and controversial topic today; there is a lot of excitement and fear. I am personally excited about it, because Artificial Intelligence is here to stay, it is in our future, and my job as an engineer is to make sure I help engineers and Artificial Intelligence, which will be good for me, my kids, and humanity.

In short, being an engineer is like being a curious cat who will work hard and work smart to make sure the next innovation he or she builds is an innovation for good rather than an innovation that may cause his or her doom.

How do we become good and successful engineers? Well, for starters, we must persevere.

Perseverance is perhaps one of the best traits to have. As engineers, we will fail—we will fail many times. It is not about failing—failure is inevitable—it is about how we deal with failure. The old “fail fast, recover fast” saying is true. We want to be able to fail, learn, and resume our work. Some days will feel like there is no solution, so we need to take a breather, sleep on it, and get back at it the next day. When we try different approaches and learn from our failures, we are bound to find a solution, or at least a partial solution that will help us move along.

Complacency is our enemy. As an engineer, we cannot, and should not, fall into the trap of complacency with our everyday tasks. As an engineer, if you reach a point where you stop trying to improve things, you are not being a good engineer. A good and successful engineer will look at better ways of doing things, improving on existing processes, and innovating.

Finally, to become a successful engineer, you must have a strong and positive attitude. You must not keep quiet when you see something is not quite right, when you feel something will not work, or something may endanger yourself or others. You must be strong and accept criticism— take it as an opportunity to learn rather than take it personally. We have all been criticized at some point in our lives for our work. Criticism is an opportunity to come back stronger and show that we can improve our work. However, do not let criticism get you down. And always give good feedback and positive criticism, because like you, others will also need that opportunity to learn from their mistakes. Be proactive, help when you can, and ask for help when you need it. Don’t be afraid to ask for help. Some people say to let our work speak for us, this is true, but you must also be your own marketing department. Good engineers will do great work, as good or better than yours. It is your responsibility to showcase your work, push your work, and market your work, so that others appreciate it and it does not fall on deaf ears. Yes, good work speaks volumes, but there is nothing wrong with adding amplifiers.

So, be a curious cat, be an innovator, be a creator, persevere, never be complacent, and have a great attitude. Don’t just be an engineer, be an awesome engineer!

9 Non-Clinical Healthcare Careers to Consider

LinkedIn
Media assistants sitting a table together

It’s hard to ignore the healthcare field if you’re searching for a stable career. The Bureau of Labor Statistics (BLS) reports that the healthcare field is expected to add 2.4 million new jobs from 2016 to 2026—which is more than any other occupational group!

There’s no denying that there are plenty of opportunities waiting for you in healthcare. But what if you don’t see yourself working in direct patient care? Luckily you don’t have to work in a clinical setting to take advantage of a career in the booming healthcare industry.

The healthcare field revolves around caring for people, but it takes more than just doctors and nurses to make it happen. High-quality healthcare gets plenty of support from non-clinical workers who take care of administrative tasks, coordinate care efforts, manage technology and more.

These non-clinical healthcare occupations are a valued part of the medical field and play an important part in keeping the healthcare industry running smoothly. Explore these non-clinical healthcare career descriptions to find the one that’s the best fit for you.

  1. Medical coder

In a sense, medical coders are the translators of the healthcare industry. They convert patients’ medical records and physicians’ notes into specially designed codes so insurance companies can accurately bill for the services patients receive. Because these healthcare professionals have access to sensitive patient information, they also need to be well-versed in government regulations surrounding healthcare privacy and electronic health records.

This role may sound simple, but it keeps a healthcare provider’s financial records in tip-top shape.

  1. Health information technician

Technology is changing the way the healthcare industry works, especially where electronic health records (EHRs) are involved. Health information technicians (HITs) ensure that a patient’s EHRs are accurate and secure. They also analyze data on patient outcomes.

Like medical coders, HIT professionals are expected to stay current with regulations about patient privacy.

  1. Healthcare manager

Healthcare managers oversee the day-to-day operations of a medical department. They set and monitor budgets, train new staff members to their team and look for ways to increase efficiency and quality of care.

Healthcare managers set the tone for their department and their team, so their leadership influences every patient who walks through a facility’s doors.

  1. Medical administrative assistants

Medical administrative assistants, sometimes called medical secretaries, are often the smiling faces you see when you first enter a medical facility. These administrative experts greet patients and provide customer service, schedule appointments, enter insurance information and work with patient billing.

Medical administrative assistants keep a healthcare facility running smoothly behind the scenes, and they make patients feel welcome and cared for.

  1. Healthcare administrator

Healthcare administrators are the leaders of their medical facility. They set financial goals for their facility, create policies that benefit patient care and ensure that their facility stays in compliance with healthcare regulations.

Healthcare administrators might seem far removed from patient care, but their work directly impacts the quality of care a facility is able to provide.

  1. Community health worker

Community health workers focus on improving the well-being of the people in a particular area or region. Their tasks include educating community members on important health issues, reaching out to at-risk populations to improve their health and assisting with disaster preparedness. These healthcare workers are in the unique position to impact individuals’ general well-being on a large scale.

  1. Human service assistants

Human service assistants work with patients to help them arrange the medical care and other services they need. Their work varies depending on the population they serve. Human service assistants who focus on the elderly might help patients arrange transportation to the doctor, set up a meal delivery service or navigate Medicare. Those who work with people with disabilities might help them arrange personal care services or find a job that accommodates their disability.

Human service assistants spend their days making it easier for patients to navigate a complex healthcare system so they can live their lives to the fullest.

  1. Corporate wellness coordinator

Corporate wellness coordinators work at the intersection of healthcare and business. These healthcare pros bring wellness programs to corporations to help their employees improve their overall health—which in turn gives a boost to the company’s bottom line. They often run fitness initiatives and evaluate individuals for health risks.

This healthcare career puts the spotlight on wellness so individuals can be aware of their risk factors and take control of their health.

  1. Patient advocate

It can be easy for patients to feel overwhelmed in a medical setting, especially if they’re experiencing health issues. Patient advocates help bridge this gap by explaining medical terms and procedures to patients, ensuring they have access to the treatments they need and helping them understand their treatment plan. Patient advocates also communicate a patient’s concerns to doctors or nurses.

Patient advocates dedicate themselves to making sure patients feel heard. They’re the ones patients can turn to if they need support and aren’t sure what to do.

Yes, tech companies may listen when you talk to your virtual assistant. Here’s why that’s not likely to stop

LinkedIn

Big tech companies don’t like to talk about it. And when users find out it’s happening, they’re often surprised — and disturbed. Yes, if you talk to a virtual assistant, such as Amazon’s Alexa, a human may listen to a recording of your chatter.

Recent reports have highlighted what is actually a longstanding practice meant largely to improve the artificial intelligence that underpins the virtual assistant-powered gadgets and services that are popping up throughout people’s homes and lives.

The practice raises privacy concerns for smart-speaker users in particular, who might have known that Amazon, Google, and Apple create recordings each time you speak to Alexa, Google Assistant, and Siri, respectively, but not that people might review them.

The companies have said only a small percentage of recordings are listened to by humans. Still, Google and Apple have temporarily halted human reviews of their recordings, while Amazon recently changed its settings to make it easier for people to avoid such review at all.

Last week, Facebook said it, too, had paused human review of some users’ audio clips, such as those sent as audio messages via the social network’s Messenger app. Facebook had been using humans to listen in, as part of an AI-transcription feature.

Lost in the shuffle of these revelations is whether people are truly needed to make these AI-dependent systems work, and how much companies should tell users about this process.

Race car driver Jessi Combs, known as the ‘fastest woman on four wheels,’ dies while trying to beat record

LinkedIn

Race car driver Jessi Combs, who earned the title of the “fastest woman on four wheels” after she set a record with a jet-powered car, died Tuesday while trying to beat a land speed record, officials said.

Combs died Tuesday in Alvord Desert in southeast Oregon, the Harney County Sheriff’s Office said. She was 39.

“She was a brilliant & to[p]-notch builder, engineer, driver, fabricator, and science communicator, & strove everyday to encourage others by her prodigious example,” said Adam Savage, former co-host of the TV show “Mythbusters.”

Combs appeared in multiple episodes of the show, while host Kari Byron was on maternity leave. She also appeared as a host in shows such as “All Girls Garage” and “Overhaulin’.”

Combs became the fastest woman on four wheels in 2013 at the North American Eagle Supersonic Speed Challenger, when she set a record of 398 mph.

In October, Combs set a new top speed of 483.2 mph in a shakedown run.

On Tuesday, she was attempting to go faster when she crashed.

“On August 27, 2019 at approximately 4:00PM the Harney County 911 Center received a call reporting that a jet car attempting to break a land speed record on the Alvord Desert had crashed leading to one fatality,” the sheriff’s office said.

Her resume was full of firsts: the first woman to place at any Ultra4 event; the first woman to compete in The Race of Gentlemen event.

Savage also tweeted “I’m so so sad, Jessi Combs has been killed in a crash. She was a brilliant & too-notch builder, engineer, driver, fabricator, and science communicator, & strove everyday to encourage others by her prodigious example. She was also a colleague, and we are lesser for her absence.”

Her dedication to women’s empowerment in the automotive industry was also significant. She has a line of women’s welding gear with Lincoln Electric, as well as an online collaborative dedicated to empowering and educating women through industrial skills, called the RealDeal.

Associating colors with vowels? Almost all of us do!

LinkedIn
man thinking about colors

Does [a:] as in ‘baa’ sound more green or more red? And is [i:] as in ‘beet’ light or dark in colour? Even though we perceive speech and colour are perceived with different sensory organs, nearly everyone has an idea about what colours and vowels fit with each other. And a large number of us have a particular system for doing so. This is shown in research by linguists from Radboud University and the University of Edinburgh on similarities in the vowel-colour associations perceived by over 1,000 people.

For the writer Vladimir Nabokov, “aa” was the colour of polished ebony and “ee” was yellow. Nabokov had synaesthesia: his sensory perceptions mingled with one another. In his case, he saw colours when hearing certain vowels, but many forms of synaesthesia are possible. Only 1 in 25 people have synaesthesia, but this new research shows that certain intuitions about “sound colours” shared by many more people than this.

“Aa” is more red than green

In this study, over 1,000 people took part in an online test where they chose colours for 16 spoken vowels. A large majority felt that “aa” was more red than green, and “ee” more light than dark, whether they had synaesthesia or not. According to Mark Dingemanse, one of the researchers, “There seems to be a logic to how we link sound and colour, and the structure of language has an important role in this process.”

Vowel space

Sixteen vowels sounds like a lot, but it works like this. When you say “aa,” then move to “oo” as in boot and then to “ee” as in beet, Dingemanse explains, you have visited the three outer points of what linguists call the vowel space. The 16 spoken sounds in our study were evenly distributed over this space.

Vowel system dictates colour associations

Earlier studies have found that colour associations are linked to the pitch of the sounds: the higher the pitch, the lighter the colour. But the new study shows that colour associations are driven to a greater degree by the vowel system of a language. For example, many participants described sounds that were close to the Dutch vowel “ee” as light green, while nearby sounds resembling “ay” as in say were assigned a different colour. The associations are shaped according to how our language carves up the vowel space.

Dingemanse says, “If colour associations were purely dependent on acoustical factors, the colours would neatly run into one another like in a rainbow. Instead, we see that sounds are grouped according to the way that our language carves up the vowel space: a few blue spots and then suddenly a red one, with no transition of blue-purple-red. You could say that the vowels have to pass through the sorting machine that is our language before we can link colours to them, even in synaesthetes, for whom associations like these are involuntary.”

Synaesthesia

The researchers used a new method to dig deeper into the structure of the colour associations. For each participant, they compared the chosen vowel-colour associations with a random sample of 10,000 random associations. They used this to measure how systematic the chosen associations were.

“Synaesthetes’ associations were more systematic than those of non-synaesthetes,” says Christine Cuskley of Edinburgh University. “But some patterns occur everywhere: people seem to align the vowel space and colour space with each other and connect the dots from one space to the other.” For instance, colours chosen for “ee” and “ay” tend to be quite close to each other, while those for “aa” and “oo” are further apart. Automatic associations like those of synaesthetes therefore rely on some of the same principles that non-synaesthetes use to link vowels and colours.

The study took place as part of the so-called Great National Research Project (GNO), a collaborative venture of Radboud University, the Netherlands Organisation for Scientific Research (NWO) and NTR Broadcasting.
