New Wearable Device Measures Changing Size of Tumors Below the Skin
Engineers a have created a small, autonomous device with a stretchable/flexible sensor that can be adhered to the skin to measure the changing size of tumors below. The non-invasive, battery-operated device is sensitive to one-hundredth of a millimeter (10 micrometers) and can beam results to a smartphone app wirelessly in real-time with the press of a button.

Scientists Reveal Dark Matter Around Galaxies 12 Billion Years Ago
One of Nagoya University's leading research centers has made another groundbreaking discovery, looking back into parts of space further than ever before. Seeing something that happened such a long time ago is difficult. Because of the finite speed of light, we see distant galaxies not as they are today, but as they were billions of years ago. But even more challenging is observing dark matter, which does not emit light.

Wearable Chemical Sensor is Good as Gold
Researchers created a special ultrathin sensor, spun from gold, that can be attached directly to the skin without irritation or discomfort. The sensor can measure different biomarkers or substances to perform on-body chemical analysis. It works using a technique called Raman spectroscopy, where laser light aimed at the sensor is changed slightly depending on whatever chemicals are present on the skin at that point. The sensor can be finely tuned to be extremely sensitive, and is robust enough for practical use.

Scientists Craft Living Human Skin for Robots
From action heroes to villainous assassins, biohybrid robots made of both living and artificial materials have been at the center of many sci-fi fantasies, inspiring today's robotic innovations. It's still a long way until human-like robots walk among us in our daily lives, but scientists from Japan are bringing us one step closer by crafting living human skin on robots. The method developed not only gave a robotic finger skin-like texture, but also water-repellent and self-healing functions.

Electronics Grow on Trees Thanks to Nanocellulose Paper Semiconductors
Semiconducting nanomaterials with 3D network structures have high surface areas and lots of pores that make them excellent for applications involving adsorbing, separating, and sensing. However, simultaneously controlling the electrical properties and creating useful micro- and macro-scale structures, while achieving excellent functionality and end-use versatility, remains challenging.

Silver Plus Chemicals Create Antimicrobial Textile Coating
For the first time, researchers have found a cost-effective and convenient way to apply a silver-based antimicrobial clear coating to new or existing textiles. Their method uses polyphenols, commonly found in food items notorious for staining clothes such as wine and chocolate. A range of textile types can be treated by the researchers' method, and items can be washed multiple times without losing the antimicrobial and therefore anti-odor property.

Exploring Human-Body Communications with Binaural Hearing Aids
Wearable technology seems all poised to take over next-generation electronics, yet most wireless communication techniques are not up to the task. To tackle this issue, scientists delved deep into human-body communications, in which human tissue is used as the transmission medium for electromagnetic signals. Their findings pave the way to more efficient and safer head-worn devices, such as binaural hearing aids and earphones.

The Future of Semiconductors is Clear
Mobility is a key parameter for semiconductor performance and relates to how quickly and easily electrons can move inside a substance. Researchers have achieved the highest mobility among thin films of tin dioxide ever reported. This high mobility could allow engineers to create thin and even transparent tin dioxide semiconductors for use in next-generation LED lights, photovoltaic solar panels or touch-sensitive display technologies.
