Tiny New Sensor โ€” That Could Fit in a Smartphone โ€” Makes the Invisible Visible

Miniaturized near-infrared sensor that could fit in a smartphone can analyze the chemical content of milk and plastics.

A TU/e research group has developed a new near-infrared sensor that is easy to make, comparable in size to sensors in smartphones, and ready for immediate use in industrial process monitoring and agriculture. This breakthrough has just been published in Nature Communications.

The human eye is a marvelous sensor. Using three different types of photoreceptor cone cells that convert visible light into signals for different colors, the eye gives essential information about the world around us.

After an injury, nerves often struggle to regrow completely, leaving patients with reduced mobility and sensation. In tests on rats, Irish researchers have now demonstrated a way to improve nerve repair using proteins from the supporting network around cells.

Peripheral nerves have some capacity for regeneration after an injury, but they often need help. For major damage, sections can be surgically replaced with nerves taken from other parts of the patientโ€™s body, but that obviously creates injuries elsewhere. Implants called nerve guidance conduits (NGCs) are often used, which, as the name suggests, help direct nerves to regenerate along specific paths.

Thread robot is designed to remove blood clots in brain

MIT team develops steerable soft thread-like robot capable of navigating tiny blood vessels

Snake robots are among the most familiar type of mechanical device for working in confined spaces. Flexible, tubular robots have been used for applications such as working in the interior of nuclear reactors, water distribution systems and inside the human body to aid surgery. The MIT team, mechanical engineers affiliated to the institutionโ€™s Institute for Soldier Nanotechnologies, have downsized the snake paradigm to the scale of a thread half a millimetre in diameter, which can be remotely controlled by magnetic fields to worm its way through the convoluted blood vessels of the brain to deliver clot-busting drugs or devices to break up and remove the blockage. Such robots have the potential to quickly treat a stroke and prevent damage to the brain, the team claims.

Arduino Meets Quantum Computer

| Hackaday


Quantum computers arenโ€™t quite ready for the home lab, but since there are ways to connect to some over the Internet, you can experiment with them more easily than you might think. [Norbert] decided to interface a giant quantum computer to an ordinary Arduino. Why? Well, that isnโ€™t necessarily clear, but then again, why not? He explains basic quantum computing and shows his setup in the video below.

Using the IBM quantum computer and the open source Qiskit makes it relatively easy, with the Python code heโ€™s using on the PC acting as a link between the Arduino and the IBM computer. Of course, you can also use simulation instead of using the real hardware, and for such a simple project it probably doesnโ€™t matter.

Granted, the demo is pretty trivial, lighting an LED with the state of qubit. But the technique might be useful if you wanted to, say, gather information from the real world into a quantum computer. You have to start somewhere.
