Wearable heart monitoring system that even works during a workout

Engineers and physicians have developed a wearable ultrasound device that can assess both the structure and function of the human heart. The portable device, which is roughly the size of a postage stamp, can be worn for up to 24 hours and works even during strenuous exercise. The goal is to make ultrasound more accessible Read more about Wearable heart monitoring system that even works during a workout[…]

A new field of neuroscience called connectomics

Many of us have seen microscopic images of neurons in the brain — each neuron appearing as a glowing cell in a vast sea of blackness. This image is misleading: Neurons don’t exist in isolation. In the human brain, some 86 billion neurons form 100 trillion connections to each other — numbers that, ironically, are Read more about A new field of neuroscience called connectomics[…]

Decoding brain waves acoustic information

Researchers at the University of Essex hope the project could lead to helping people with severe communication disabilities such as locked-in syndrome or stroke sufferers by decoding language signals within their brains through non-invasive techniques. Dr Ian Daly, from Essex’s School of Computer Science and Electronic Engineering who led the research, said: “This method has Read more about Decoding brain waves acoustic information[…]

Microring sensors for electrolyte analysis

In the human body, electrolytes play a key role in maintaining water balance and distribution of fluids. All charged particles dissolved in the blood interact with each other. If a disturbance to their complex equilibrium is suspected, the concentration of a variety of these microminerals will be analyzed. Researchers from the Fraunhofer Institute for Telecommunications, Read more about Microring sensors for electrolyte analysis[…]

New smart bandage’s biosensing

Some wounds just won’t heal. Infections, diseases like diabetes, and suppressed immune systems often stack up to slow healing. Chronic wounds can last months and lead to anxiety and depression. In the worst cases, they are life threatening. Cost of treatment has soared to $25 billion each year. So far, however, solutions for treating chronic Read more about New smart bandage’s biosensing[…]

A fingertip-sized chip replaces bulky laboratory equipment

In analytical chemistry, it is often necessary to accurately monitor the concentration change of certain substances in liquids on a time scale of seconds. Especially in the pharmaceutical industry, such measurements need to be extremely sensitive and reliable. A new type of sensor has been developed at TU Wien which is highly suitable for this Read more about A fingertip-sized chip replaces bulky laboratory equipment[…]

AI algorithm from CTA images accurately predicted heart attack risk

Investigators from Cedars-Sinai have created an artificial intelligence-enabled tool that may make it easier to predict if a person will have a heart attack. The tool, described in The Lancet Digital Health, accurately predicted which patients would experience a heart attack in five years based on the amount and composition of plaque in arteries that supply blood to Read more about AI algorithm from CTA images accurately predicted heart attack risk[…]

A new 3D printed vaccine patch that outperforms needle jab to boost immunity

Scientists at Stanford University and the University of North Carolina at Chapel Hill have created a 3D-printed vaccine patch that provides greater protection than a typical vaccine shot. The trick is applying the vaccine patch directly to the skin, which is full of immune cells that vaccines target. The resulting immune response from the vaccine patch was 10 times Read more about A new 3D printed vaccine patch that outperforms needle jab to boost immunity[…]

What if that second medical opinion could be generated by a computer, using artificial intelligence?

It’s an old adage: there’s no harm in getting a second opinion. But what if that second opinion could be generated by a computer, using artificial intelligence? Would it come up with better treatment recommendations than your professional proposes? A pair of Canadian mental-health researchers believe it can. In a study published in the Journal of Applied Behavior Read more about What if that second medical opinion could be generated by a computer, using artificial intelligence?[…]

The future of 3D-print bone parts

Scientists from UNSW Sydney have developed a ceramic-based ink that may allow surgeons in the future to 3D-print bone parts complete with living cells that could be used to repair damaged bone tissue. Using a 3D-printer that deploys a special ink made up of calcium phosphate, the scientists developed a new technique, known as ceramic Read more about The future of 3D-print bone parts[…]

Novel design and strategic use of materials for wearable biosensors

In recent years, the use of wearable sensing devices has become a part of people’s everyday lives. Devices such as smart watches, for example, can be used to monitor physical fitness functions such as heart rate, sleep and exercise. But advances in technology have opened many more possibilities for monitoring patient health. Sensors can now Read more about Novel design and strategic use of materials for wearable biosensors[…]
