The "white cane" that many blind people rely on for navigating the world hasn't been upgraded in a century, but researchers are reporting progress on a "robo-cane" they hope will modernize the assistive device.

The prototype cane is equipped with a color 3D camera, sensors and an "on-board" computer designed to guide the user to a desired location and avoid any obstacles alon...

Until now, folks suffering from hearing loss typically have had to fork out thousands of dollars for a device that could be adjusted only by a professional audiologist.

No wonder that only one-quarter of the nearly 29 million U.S. adults who could benefit from a hearing aid have actually tried one, according to the U.S.

  • A good Samaritan can save the life of someone in cardiac arrest if a portable defibrillator is nearby. Now, a pilot study suggests a new way to get the devices into bystanders' hands: drones.

    The study, done in Sweden, found that drone delivery was a feasible way to get automated external defibrillators (AEDs) to the scene of a cardiac arrest. In fact, the drones typically beat ambulances...

    A first-of-a-kind nerve stimulation treatment for people who have problems moving their arms after a stroke has been approved by the U.S. Food and Drug Administration.

    "People who have lost mobility in their hands and arms due to ischemic stroke are often limited in their treatment options for regaining motor function," explained Dr. Christopher Loftus. He is acting director of the FDA's ...

    A new approach to spinal cord stimulation may drastically reduce chronic back pain, a small pilot study suggests.

    The study, of 20 patients with stubborn low back pain, tested the effects of implanting electrodes near the spinal cord to stimulate it with "ultra-low" frequency electrical pulses.

    After two weeks, 90% of the patients were reporting at least an 80% reduction in their pa...

    Do you have an implanted defibrillator or pacemaker? Try keeping your smart watch or smart phone a few inches away from them.

    New research from the U.S. Food and Drug Administration finds that your phone or watch could interfere with implanted heart devices.

    Based on the new findings, heart patients and health care providers should be aware of potential risks, the research team...

    Spit and scan. That's all you have to do, and in less than an hour, you can not only find out if you have COVID-19 but what variant you have, all without leaving your home.

    This is the hope and promise of a new saliva-based COVID-19 test that is currently under development.

    "Several at-home tests are available for telling you whether you have COVID-19, but none of them test for vari...

    Researchers have developed an implant that allowed a man with severe paralysis to "speak" again by translating his brain signals into text.

    The achievement is the latest step in "brain-computer interface" (BCI) research.

    Scientists have been studying BCI technology for years, with the aim of one day giving people with paralysis or limb amputations greater independence in their daily...

    Modern, flexible boots may be just as good as old-school plaster casts when it comes to treating broken ankles, new research suggests.

    Often related to sports, traffic accidents or falls, broken ankles can be simple breaks in one bone or more complicated fractures that involve several bones, according to the American Academy of Orthopaedic Surgeons. Ankle fractures don't always require su...

    A quick daily "workout" for the breathing muscles may help people lower their blood pressure to a similar degree as exercise or even medication, a small study suggests.

    The technique is called inspiratory muscle strength training (IMST), and it involves using a device that provides resistance as the user inhales -- essentially working out the diaphragm and other breathing muscles.

    R...

    The notion of parents picking out genetically perfect babies may seem like science fiction, but bioethicists warn in a new report that some companies have already started to offer couples going through in vitro fertilization (IVF) the means to pick better embryos through polygenic scoring.

    Polygenic scores are a "weighted average of the contributions of all of the genes we have informatio...

    Early research suggests that CRISPR gene-editing technology may some day lead to dramatic relief for patients struggling with amyloidosis, a rare but serious disease that can trigger organ failure.

    "There are many different types of amyloidosis," explained study author Dr. Julian Gillmore, a researcher in medicine with the Centre for Amyloidosis and Acute Phase Proteins at University Coll...

    Good news for couples considering fertility treatments: Children born through assisted reproductive technology (ART) don't have an increased risk of cancer, researchers say.

    In the new study, kids born through high-tech fertility treatments -- such as in vitro fertilization (IVF) and frozen embryo transfer (FET) -- were followed for 18 years on average.

    The results should be "quite ...

    Researchers are reporting early success with a temporary heart pacemaker that simply dissolves when it's no longer needed.

    So far the work has been limited to animals and human heart tissue studied in the lab. But experts said the early findings are "exciting" and could eventually change the care of patients who need a pacemaker for only days to weeks.

    Pacemakers are devices that ar...

    Your health and fitness apps may have privacy issues that put your personal information at risk, researchers warn.

    "This analysis found serious problems with privacy and inconsistent privacy practices in mHealth [mobile health] apps. Clinicians should be aware of these and articulate them to patients when determining the benefits and risks," lead study author Muhammad Ikram and his co-aut...

    Norman Mayer, 86, walks around with a computer chip in his chest and doesn't think a thing about it.

    Doctors implanted a tiny heart monitor chip in Mayer's chest after he suffered a mini-stroke in late 2015, to track his heartbeat and potentially detect an irregular heart rhythm called atrial fibrillation (a-fib).

    "You don't even know it's there," said Mayer, the sitting mayor of th...

    Patients facing relatively simple outpatient surgeries are nonetheless being told to undergo a number of preoperative tests that just aren't necessary, a new study reports.

    More than half of a group of patients facing low-risk outpatient surgery received one or more tests -- blood work, urinalysis, an electrocardiogram (EKG), a chest X-ray -- prior to their operation.

    One-third of p...

    When someone comes in for a new heart stent, it's critical that the medical team doing the procedure knows several key facts about previous stents the patient has had.

    But fewer than half of patients receiving a stent were still carrying the stent card that has those details with them, a new study finds.

    Most of them - about 88% - do carry their phones, according to study author D...

    The U.S. Food and Drug Administration is warning that strong magnets in some cellphones and smartwatches can interfere with pacemakers and other implanted medical devices.

    Studies have shown that these high-strength magnets may cause some implants to switch to "magnet mode," stopping normal functioning until the magnet is moved away from the device.

    Many implants have a "magnet mode...

    A microchip implanted in the brain has allowed a paralyzed man to communicate by text -- at speeds that approach the typical smartphone user.

    The achievement is the latest advance in "brain-computer interface" (BCI) systems.

    Scientists have been studying BCI technology for years, with the aim of one day giving people with paralysis or limb amputations greater independence in their ...

    Two widely used COVID-19 vaccines -- Pfizer and Moderna -- will likely remain powerfully protective against developing serious illness even if coronavirus variants somehow manage to infect vaccinated patients, new research suggests.

    Both vaccines are based on messenger RNA (mRNA) technology. And investigators say that, at least in theory, such technology can deploy multiple levels of defe...

    A few days after his 74th birthday, Don Stivers received his dream gift -- a new heart.

    "I was born with a very lousy heart," he explained. "Growing up, I decided I was going to overcome it and go to the Olympics and be a strong boy. And so everything I did was against doctors' orders. They said don't run, don't do this, but I did anyway, and I would turn blue and pass out, and my mother...

    For those who suffer painful arthritis in their aging knees, new research suggests a noninvasive treatment might deliver lasting relief.

    Called genicular artery embolization, the roughly two-hour catheter treatment involves a once-and-done injection of tiny hydrogel particles into arterial pathways in the knee joint. The goal: To decrease overall blood flow in the joint, and thereby marke...

    Looking to shed some of those pandemic pounds? A new analysis says wearables like Fitbit and Apple Watch can help people slim down.

    The researchers examined studies involving commercial health wearables and adults who were overweight/obese or had a chronic health condition.

    After daily moderate-to-vigorous physical activity for a period between a month and a year, participants lost ...

    One in four U.S. households use smart speakers to check the weather, play music and query search engines. But a new technology may soon have folks asking, "Hey Google, how's my heart?"

    Researchers from the University of Washington, Seattle, have developed a skill for Amazon Alexa and Google Home that allows the devices to check heart rhythms.

    Like a bat using echolocation to hunt fo...

    A new type of surgery offers amputees better control of muscles that remain after surgery, and of their prosthetic limbs, its inventors say.

    The standard surgical approach to amputation has changed little since the American Civil War, according to developers of the new approach. In their small study, the new procedure also helped curb pain and sensations like the troubling "phantom limb" ...

    Access to potentially lifesaving 3D mammography isn't equal, new research shows.

    "This study was about whether adoption of this technology is equitable. We're showing that it has not been, even though it has been [U.S. Food and Drug Administration]-approved for a decade now," said Dr. Christoph Lee. He is professor of radiology at the University of Washington School of Medicine, in Seattl...

    A steady sleep routine may do more than keep you well-rested: New research suggests that the more swings in your slumber schedule, the worse your mood and depression symptoms are likely to be.

    Researchers from Michigan Medicine followed the sleep patterns of interns in their first year of residency after medical school. That irregular sleep schedule can increase a person's risk of depress...

    As the new coronavirus vaccine rollout gathers speed, elevators will likely become a flash point for businesses hoping to reopen offices while sticking to social distancing.

    And a new computer simulation suggests that the usual "first-come, first-served" elevator routine is neither safe nor practical.

    "Now that vaccines are within reach, many buildings are slated for phased re-openi...

    The U.S. Food and Drug Administration on Friday approved the marketing of a new "tongue strengthening" device to cut down on snoring in patients with mild obstructive sleep apnea.

    Unlike devices used during sleep, this prescription device is used while awake, and is designed to stimulate and strengthen the tongue so that it doesn't collapse backward and obstruct the breathing airway durin...

    Stroke survivor Ken Allsford focused intensely on how he wanted to bend his elbow.

    And then the robot exoskeleton attached to his left arm obeyed his unspoken command, moving his crippled limb.

    "It was a combination of exciting and trepidation, because sometimes nothing would happen," Allsford, 61, of Katy, Texas, recalled. "But when you actually see it move without actually making ...

    Telemedicine rapidly expanded during the COVID-19 pandemic as people turned to their phones and computers rather than leave their homes for health care.

    But some groups of people were left behind in the telemedicine boom, a new study reports.

    Middle-aged and older folks are much less likely to complete their scheduled telemedicine visits, as well as Medicaid recipients and those who...

    In late December, Dr. Ada Stewart asked her staff to check on a patient who had missed an appointment.

    She soon learned that the patient had no transportation for the 45-minute drive, so Stewart offered to conduct the appointment by phone instead.

    "It still accomplished so much. I was able to see how their diabetes was doing, how they were preparing for the holiday seaso...

    Adults living with kidney failure are receptive to using mobile devices to help with their care, according to a new study.

    Mobile health can provide many benefits for patients, especially for those whose care is complicated and who have dietary restrictions, researchers said. Whether people on dialysis are ready to incorporate mobile technology in their care would be a limiting factor.

    For years, people with implanted heart devices have been told they can't undergo MRI scans. But a new study adds to evidence that, with certain measures in place, the procedure is safe.

    The study focused on patients with older pacemakers and implantable defibrillators that were not designed to be more compatible with MRI scanners. The researchers found that when a particular protocol ...

    Wide variation exists in the accuracy of commercial testing kits that check for antibodies against the new coronavirus, researchers say.

    Antibody tests can determine whether someone has had the virus in the past. For diagnosis at a later stage of illness or in cases of delayed-onset, antibody tests could also be an important part of hospital diagnosis, the study authors said in the ne...

    An artificial pancreas system is safe and effective at managing blood sugar levels in kids as young as age 6 with type 1 diabetes, according to a new study.

    The system uses a continuous glucose monitor (CGM) to track blood sugar levels and automatically delivers insulin when needed using an insulin pump. It replaces reliance on fingerstick or CGM with delivery of insulin by injection ...

    Kids suffering from nearsightedness can slow the progression of their myopia by using soft bifocal contact lenses, a new trial shows.

    Bifocal contacts with a powerful corrective prescription slowed the progression of nearsightedness in youngsters by 43% compared to single-vision contacts, the results showed.

    "The higher the reading portion of the contact lens, the better...

    Virtual medical visits have been invaluable for many during the COVID-19 pandemic, but older adults may still need help managing them -- especially if they are hard of hearing.

    That's according to doctors at Johns Hopkins University, in Baltimore. Writing in the Aug. 11 Annals of Internal Medicine, they offer some practical advice on navigating "telemedicine."

    First a...

    The coronavirus pandemic has fueled big increases in video visits between patients and doctors, but older Americans haven't easily taken to the trend, a new study finds.

    More than one-third of those over 65 face difficulties seeing their doctor via telemedicine -- especially older men in remote or rural areas who are poor, have disabilities or are in poor health.

    "Telemedi...

    If you ever had a sex-ed class in school, you have probably seen a visual of sperm swimming with a wagging tail. Now, high-tech tools have shattered that view of how sperm move.

    More than 300 years ago, a Dutch scientist used an early microscope to observe human sperm in motion. He saw that they appeared to swim using a tail that moved from one side to the other.

    But scient...

    Stroke patients in rural areas of the United States are less likely to get cutting-edge treatments and more likely to die than those in cities.

    That's the takeaway from a new analysis of nationwide data on more than 790,000 adults who were hospitalized with stroke between 2012 and 2017. Most were 64 or older.

    Compared to patients in cities, those treated at rural hospitals w...

    Technology often makes life easier to manage, and new research confirms that's definitely the case for people with type 1 diabetes.

    Continuous glucose monitors -- devices that approximate blood sugar levels every few minutes -- can help teens and young adults better manage their diabetes. They can also help older adults prevent dangerously low blood sugar levels (hypoglycemia), accor...

    The first video game to help treat kids with attention-deficit/hyperactivity disorder (ADHD) has been approved by the U.S. Food and Drug Administration.

    EndeavorRx is a prescription-only game designed to help improve attention in 8- to 12-year-olds with ADHD who have confirmed attention problems.

    It is the first game-based treatment authorized by the FDA for any condition.

    Streaks of color swirl through a pulsing, black-and-white image of a patient's heart. They represent blood, and they're color-coded based on speed: turquoise and green for the fastest flow, yellow and red for the slowest.

    This real-time video, which can be rotated and viewed from any angle, allows doctors to spot problems like a leaky heart valve or a failing surgical repair with unpr...

    Bright yellow and looking like a headless deer, Spot can travel across ground too risky for humans. "Built for dirt and danger," in the words of its maker Boston Dynamics, this robot is now helping humans battle a different threat: the spread of coronavirus.

    Equipped with an iPad and two-way radio, Spot has been making the rounds at Brigham and Women's Hospital in Boston since April. ...

    Back before coronavirus took over the headlines, every week seemed to bring another report about artificial intelligence besting human doctors at everything from diagnosing skin cancer to spotting pneumonia on chest X-rays.

    But these artificial intelligence (AI) tools -- computer programs that get better at performing a task by being "trained" on the right kind of data -- are years aw...

    An injectable electrode could prove a better way to ease chronic nerve pain than opioid painkillers or bulky and expensive implants, animal research suggests.

    It's called an "injectrode." It appears easier and cheaper than spinal implants for debilitating back pain, and safer than long-term use of opioids like OxyContin (oxycodone), a recent paper suggests.

    A liquid silicone...

    The latest addition to medical haute couture may be a necklace outfitted with a pendant that people can use to screen themselves for signs of an abnormal heart rhythm condition known as atrial fibrillation.

    Fashioned by a team of Finnish researchers, the pendant houses a portable electrocardiogram (EKG) designed to transmit heart readings to a cellphone app and ultimately to a cloud-b...

    Love to cuddle up? It might bring a 'mind meld,' too, new research shows.

    People in close physical contact appear to have synchronized brain patterns, a revolutionary new MRI technique has revealed.

    A functional MRI scan of two people cuddling under a blanket showed that their brains appeared to be falling into similar patterns of action and response, as they took turns gent...
