Drawing inspiration from the way plants breathe, a group of researchers has created a paper-based magnesium-air battery that can be used in GPS sensors or pulse oximeter sensors. Taking advantage of paper's recyclability and lightweight nature, the engineered battery holds promise for a more environmentally friendly source of energy.

Polymer-based hydrogels are used to treat skin ailments and in tissue engineering because of their ability to retain water, deliver drugs into wounds, and biodegrade. However, they are complicated to manufacture and not very resilient to external forces like rubbing against clothing, sheets, or wound dressings. Scientists have now created a hydrogel enhanced with the amino acid polylysine and blood plasma that is easier to synthesize, contains natural antibiotic properties, and promotes cell growth.

An international team working with single-atom thick crystals found TaIrTe4's transition between the two distinct topological states of insulation and conduction. The material exhibited zero electrical conductivity within its interior, while its boundaries remain conductive. The team's investigation determined that the two topological states stem from disparate origins. The novel properties can serve as a promising platform for exploring exotic quantum phases and electromagnetism.

Nearly every modern cellphone has a built-in compass, or magnetometer, that detects the direction of Earth's magnetic field, providing critical information for navigation. Now a team of researchers has developed a technique that uses an ordinary cellphone magnetometer for an entirely different purpose -- to measure the concentration of glucose, a marker for diabetes, to high accuracy.

Using state-of-the-art tissue engineering techniques and a 3D printer, researchers have assembled a replica of an adult human ear that looks and feels natural. The study offers the promise of grafts with well-defined anatomy and the correct biomechanical properties for those who are born with a congenital malformation or who lose an ear later in life.

A research team has addressed the long-standing challenge of creating artificial olfactory sensors with arrays of diverse high-performance gas sensors. Their newly developed biomimetic olfactory chips (BOC) are able to integrate nanotube sensor arrays on nanoporous substrates with up to 10,000 individually addressable gas sensors per chip, a configuration that is similar to how olfaction works for humans and other animals.

Engineers designed an 'architected' reef that can mimic the wave-buffering effects of natural reefs while providing pockets for marine life. The sustainable and cost-saving structure could dissipate more than 95 percent of incoming wave energy using a small fraction of the material normally needed.

What would you do if you walked up to a robot with a human-like head and it smiled at you first? You'd likely smile back and perhaps feel the two of you were genuinely interacting. But how does a robot know how to do this? Or a better question, how does it know to get you to smile back?

Researchers are enhancing immunotherapy effects against malignant tumors by developing and validating patent-ending poly (lactic-co-glycolic acid), or PLGA, nanoparticles modified with adenosine triphosphate, or ATP.

Entropy, the amount of molecular disorder, is produced in several systems but cannot be measured directly. A new equation sheds new light on how entropy is produced on a very short time scale in laser excited materials.

Pushing for a higher speed isn't just for athletes. Researchers, too, can achieve such feats with their discoveries. A new device called SCARF (for swept-coded aperture real-time femtophotography) can capture transient absorption in a semiconductor and ultrafast demagnetization of a metal alloy. This new method will help push forward the frontiers of knowledge in a wide range of fields, including modern physics, biology, chemistry, materials science, and engineering.
