A novel technique for enhancing optical spring that utilizes the Kerr effect to improve the sensitivity of gravitational wave detectors (GWDs) has recently been developed. This innovative design uses optical non-linear effects from the Kerr effect in the Fabry-Perot cavity to achieve high signal amplification ratios and optical spring constant, with potential applications in not only GWDs but also in a range of optomechanical systems.

Lanthanide elements are important for clean energy and other applications. To use them, industry must separate mixed lanthanide sources into individual elements using costly, time-consuming, and waste-generating procedures. An efficient new method can be tailored to select specific lanthanides. The technique combines two substances that do not mix and that prefer different types of lanthanides. The process would allow for smaller equipment, less use of chemicals, and less waste production.

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.

One of the most fundamental interactions in physics is that of electrons and light. In an experiment, scientists have now managed to observe what is known as the Kapitza-Dirac effect for the first time in full temporal resolution. This effect was first postulated over 90 years ago, but only now are its finest details coming to light.

Windows welcome light into interior spaces, but they also bring in unwanted heat. A new window coating blocks heat-generating ultraviolet and infrared light and lets through visible light, regardless of the sun's angle. The coating can be incorporated onto existing windows or automobiles and can reduce air-conditioning cooling costs by more than one-third in hot climates.

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.

Researchers have taken a big step towards securing information against hacking. They have succeeded in using quantum encryption to securely transfer information 100 kilometers via fiber optic cable -- roughly equivalent to the distance between Oxford and London.

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.

Scientists have shown that Barkhausen noise can be produced not only through traditional, or classical means, but through quantum mechanical effects. The research represents an advance in fundamental physics and could one day have applications in creating quantum sensors and other electronic devices.
