The ideal material for interfacing electronics with living tissue is soft, stretchable, and just as water-loving as the tissue itself--in short, a hydrogel. Semiconductors, the key materials for bioelectronics such as pacemakers, biosensors, and drug delivery devices, on the other hand, are rigid, brittle, and water-hating, impossible to dissolve in the way hydrogels have traditionally been built. Scientists have now solved this challenge that has long stymied researchers, reimagining the process of creating hydrogels to build a powerful semiconductor in hydrogel form. The result is a bluish gel that flutters like a sea jelly in water but retains the immense semiconductive ability needed to transmit information between living tissue and machine.

Researchers created MobiPrint, a mobile 3D printer that can automatically measure a room and print objects onto the floor. The team's graphic interface lets users design objects in a space that the robot has mapped out. The prototype, which the team built on a modified consumer vacuum robot, can add a range of objects to rooms.

By using a water-splitting system with an aqueous electrolyte, this system is expected to block fire risks and enable stable hydrogen production.

A team of scientists has developed grain-sized soft robots that can be controlled using magnetic fields for targeted drug delivery, paving the way to possible improved therapies in future.

Researchers have developed the world's first soft touchpad that can sense the force, area and location of contact without electricity. The device utilizes pneumatic channels, enabling its use in environments such as MRI machines and other conditions that are unsuitable for electronic devices. Soft devices like soft robots and rehabilitation aids could also benefit from this new technology.

Scientists have designed a publicly-available software and web database to break down barriers to identifying key protein-protein interactions to treat with medication. The computational tool is called PIONEER (Protein-protein InteractiOn iNtErfacE pRediction). Researchers demonstrated PIONEER's utility by identifying potential drug targets for dozens of cancers and other complex diseases.

If a phone or other electronic device was made of soft materials, how would that change its use? Would it be more durable? If hospital health monitoring equipment was made of less rigid components, would it make it easier for patients to wear? While electronics of that type may still be far in the future, researchers have developed an innovative method for constructing the soft electronic components that make them up.

Lithium-sulfur batteries have never lived up to their potential as the next generation of renewable batteries for electric vehicles and other devices. But mechanical engineers have now found a way to make these Li-S batteries last longer -- with higher energy levels -- than existing renewable batteries.

Scientists have found an alternative way to produce atoms of the superheavy element livermorium. The new method opens up the possibility of creating another element that could be the heaviest in the world so far: number 120.

Fluoropolymers have become an integral part of modern society, both in industrial and consumer applications. When these high-performance materials reach the end of their useful life, they can end up in both industrial and household waste. Researchers analyzed the contribution of waste incineration of fluoropolymers to the release of low-molecular, non-polymeric fluorinated compounds. Their experiments showed nearly complete destruction of fluoropolymers in combustion at the temperatures and residence times typical of European incinerators.

Readers find automated news articles poorer than manually-written texts in relation to word choice and use of numbers.

Researchers have developed a faster and more accurate method for acquiring and reconstructing high-quality 3D surface measurements. The approach could greatly improve the speed and accuracy of surface measurements used for industrial inspection, medical applications, robotic vision and more.
