Researchers at Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland have developed a mini intestine on a chip that closely mimics the morphology and cellular composition of the small intestine. The device could be useful for advancing personalized medicine, drug screening, and even paving the way for researchers to grow new tissues and organs in the lab for use in regenerative medicine. Creating organoids typically involves assembling stem cells to form miniature versions of tissues or organs. However, existing approaches are limited in how closely they can mimic native human...Read More
Electroencephalography (EEG) devices are incredibly helpful in diagnosing and monitoring certain brain disorders, such as epilepsy and strokes. However, they are not particularly user-friendly or convenient, with specialized technicians performing time consuming procedures, such as skin preparation, to get patients ready to undergo the procedure. A combination of messy gels and wires also makes for an uncomfortable and inconvenient experience for patients. In response, Zeto Inc., a medtech startup based in California, has developed a new EEG device that sits on the head like a bicycle helmet. The headset does...Read More
The orthodontics market is expected to realize significant growth in the coming years with projected growth to $9.72 billion by 2026 ($4.06 billion in 2018). Technology advancement in the industry has largely been driven by invisible, clear aligners that can be removed for eating and cleaning. Aligners progressively reposition teeth through controlled force without the tightening required with traditional metal braces. Despite aesthetics and ease of use, an estimated 80% of patients have alignment problems that still require braces for treatment, restricting the market share that leading aligner solutions, like...Read More
Soft exosuits that provide assistive force during movement could be a game changer for patients with mobility issues. Such devices can help enhance rehabilitation and assist patients while they perform everyday tasks. The idea with such technology is that the soft suit feels almost like a piece of clothing and applies force gently and evenly to affect natural movement. This latest suit, the ReStore exosuit from ReWalk Robotics, has been FDA cleared for use in patients who have experienced a stroke and now have a mobility issue. A recent trial...Read More
Researchers at the City University of Hong Kong have developed a face mask containing laser-induced graphene that can kill bacteria and has demonstrated potential in deactivating coronaviruses. The graphene layer has antibacterial properties and can generate heat when exposed to sunlight, which may underlie its ability to deactivate coronaviruses. The researchers hope that such masks could help to reduce viral transmission and infection during the current COVID-19 pandemic. Face masks are an important part of our arsenal in the fight against COVID-19, but if used incorrectly, they can pose an...Read More

The pupil of the eye allows light to reach the retina, and a number of vision disorders are related to irregularities in the iris that surrounds the pupil. People with aniridia, for example, have some or all of the iris missing, exhibiting a large pupil that results in unfocused vision. Now, a collaboration between Imec, a Belgian research institution, Ghent University, Spain's Instituto de Investigación Sanitaria Fundación Jiménez Díaz, and Holst Centre in The Netherlands, has led to the development of an artificial iris integrated inside a contact lens that...Read More
Researchers at the Terasaki Institute for Biomedical Innovation in Los Angeles, California have developed an oxygen-releasing bioink that may be useful in 3D printing bioengineered cell constructs. This can help live cells to survive in limited oxygen environments, such as those that exist inside of 3D printed devices, in the first days after implantation. Heart cells in a bioink (top) without oxygen support and (bottom) with oxygen-releasing capabilities. Live cells are stained green, dead cells in red. Developing cell-encapsulating constructs, consisting of regenerative cells in a supportive biomaterial matrix, holds...Read More
Polarean Imaging, a company based in North Carolina, is pursuing regulatory approval for clinical use of its hyperpolarized gas MRI. The technology is intended to assist in diagnosing respiratory conditions, something that would be particularly useful during the ongoing COVID-19 pandemic. Specifically, Polarean produces equipment to generate hyperpolarized 129Xenon (HPX) or helium gas. In practice, the patient inhales some of the hyperpolarized gas, and then undergoes a 10-20 second MRI scan. Data published to date about the technology suggests that HPX MRI can enhance the MRI signal by 100,000-fold. Such...Read More

Microrobotics researchers have been working for decades, in a seemingly futile attempt, to keep up with the miniaturization that has been achieved in the field of microelectronics. Although rudimentary microscopic robots have been developed, they have failed to take full advantage of conventional silicon electronics and so are limited in their functionality. Specifically, no one has developed an actuator at micrometer resolutions that can work with semiconductor processing and be triggered using conventional electronic signals. Now, researchers from Cornell University are reporting in the journal Nature that they have successfully...Read More
Researchers at UC San Francisco have used an electrocorticography (ECoG) implant to develop a brain-computer interface that does not need to be recalibrated and retrained each time it is used, allowing an experienced user to plug in and begin using the system at any time. The technique could allow for brain controlled prosthetic limbs or wheelchairs for disabled people. “The brain computer interface field has made great progress in recent years, but because existing systems have had to be reset and recalibrated each day, they haven't been able to tap...Read More
Over 300,000 women in the US are expected to be diagnosed with breast cancer this year, with an estimated 12,000 of those diagnosed expected to be under the age of 40. Early detection is pivotal to ensuring a high likelihood of survival, which is why the Keep A Breast Foundation is doubling down on the importance of self-checks with their new Keep A Breast app. According to Keep A Breast Medical Director Dr. Joel Evans, "The breast self-check is the simplest and easiest way to protect your breasts. Knowing your...Read More
