A single protein called Gr8a is expressed in different organs in male and female flies and appears to play an inhibitory role in mating decision-making. The findings point to one of the ways that flies could put up behavioral barriers to protect against mating with the wrong kind of partner.

A new way to significantly increase the potency of almost any vaccine has been developed. The scientists used chemistry and nanotechnology to change the structural location of adjuvants and antigens on and within a nanoscale vaccine, greatly increasing vaccine performance in seven different types of cancer. The architecture is critical to vaccine effectiveness, the study shows.

In situ observation and recording of important liquid-phase electrochemical reactions in energy devices is crucial for the advancement of energy science. A research team has recently developed a novel, tiny device to hold liquid specimens for transmission electron microscopy (TEM) observation, opening the door to directly visualizing and recording complex electrochemical reactions at nanoscale in real-time at high resolution. The research team believes that this innovative method will shed light on strategies for fabricating a powerful research tool for uncovering the mysteries of electrochemical processes in the future.

An international research team has developed a new method for the efficient coupling of terahertz waves with much shorter wavelengths, so-called spin waves. Their experiments, in combination with theoretical models, clarify the fundamental mechanisms of this process previously thought impossible. The results are an important step for the development of novel, energy-saving spin-based technologies for data processing.

Photosynthesis in plants and some bacteria relies on light-harvesting (LH) supramolecules, which come in different structures. So far, these LH molecules have not been artificially prepared. In a recent study, scientists managed to synthesize LH nanorings via self-assembly of chlorophyll derivatives and examined the external conditions that drove their formation. Their findings could help us study artificial photosynthesis and possibly pave the way for novel materials for LH devices like solar cells.

When a scientist discovered surprising evidence that Saturn's smallest, innermost moon could generate the right amount of heat to support a liquid internal ocean, colleagues began studying Mimas' surface to understand how its interior may have evolved. Numerical simulations of the moon's Herschel impact basin, the most striking feature on its heavily cratered surface, determined that the basin's structure and the lack of tectonics on Mimas are compatible with a thinning ice shell and geologically young ocean.

A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.

Researchers have developed a new method for manipulating information in quantum systems by controlling the spin of electrons in silicon quantum dots. The results provide a promising new mechanism for control of qubits, which could pave the way for the development of a practical, silicon-based quantum computer.
