The microelectronic robot is 0.8 mm long, 0.8 mm wide and 0.14 mm tall. To compare: a one cent piece has a diameter of around 16mm. The micro-robot is extremely flexible, motile and equipped with various functionalities.

Artificial intelligence is revolutionizing medical diagnostics. This is a ground-breaking development with far-reaching consequences. Naturally, many innovators are scrambling to capitalize on these advancements.

Adults with type 2 diabetes requiring insulin therapy can safely achieve good blood sugar control using regular human insulin in a wearable, patch-like insulin delivery device called V-Go.

The world has a plastics problem. Every day, approximately 8 million pieces of plastic make their way into the world's oceans and plastic pollution can now be found on every beach in the world, from busy tourist beaches to uninhabited tropical islands.

Engineers are working on developing soft, flexible neural implants that can gently conform to the brain's contours and monitor activity over longer periods, without aggravating surrounding tissue. Such flexible electronics could be softer alternatives to existing metal-based electrodes designed to monitor brain activity, and may also be useful in brain implants that stimulate neural regions to ease symptoms of epilepsy, Parkinson's disease, and severe depression.

Cardiologists need to rely on the technology at their disposal. Shortages in available donor tissue for cardiac transplantation are driving the development of cardiovascular 3D bioprinting technologies.

Empty supermarket shelves have become a common sight in recent weeks. Coronavirus Has Highlighted the Problems in Supermarket Supply: Could Vertical Farming Be The Solution?

Any device that sends out a Wi-Fi signal also emits terahertz waves —electromagnetic waves with a frequency somewhere between microwaves and infrared light. These high-frequency radiation waves, known as "T-rays," are also produced by almost anything that registers a temperature, including our own bodies and the inanimate objects around us.

The University of South Florida Health, Formlabs and Northwell Health announced they have successfully produced and tested a 3D printed nasal swab to address emergency shortages that hospitals and health care teams may face as testing for COVID-19 increases.

The ability to accurately monitor drug levels and biological molecules inside patients in real time has remained largely elusive. Most of the implantable monitors invented so far rely on high tech and expensive detectors such as CT scans or MRI. Using ultrasound - which is cheap and portable - as a means to track a disease state as in response of a tumour to a new drug or the risk of a heart attack with the rise of a diagnostic protein called troponin has always been more a Blue Sky than reality.

Can robots be effective tools in combating the COVID-19 pandemic? A group of leaders in the field of robotics say yes, and outline a number of examples.

The production of highly sensitive sensors is a complex process: it requires many different steps and the almost dust-free environment of special cleanrooms. A research team has now developed a procedure to produce extremely sensitive and energy-efficient sensors using 3D printing.

A new approach could lead to 'cornea-on-a-chip' devices that more accurately test the effects of drugs on the human eye.

Researchers have developed a nanodevice that operates more than 10 times faster than today's fastest transistors, and about 100 times faster than the transistors you have on your computers. This new device enables the generation of high-power terahertz waves. These waves, which are notoriously difficult to produce, are useful in a rich variety of applications ranging from imaging and sensing to high-speed wireless communications.

A look into the molecular diagnostic landscape.

A group of researchers has combined the ubiquitous biomasses starch, the main component of the carbohydrates found in corn, tubers, and roots such as potatoes, and cellulose, the main component of plants and commonly known as cotton fiber, to develop a marine biodegradable plastic.
