In the quest to unravel the complexities of neural circuits, scientists are beginning to use genetically encoded voltage indicators (GEVIs) to visualize electrical activity in the brain. These indicators are crucial for understanding how neurons communicate and process information. However, the effectiveness of one-photon (1P) versus two-photon (2P) voltage imaging has remained a topic of debate. A recent study by researchers at Harvard University sheds light on the relative merits and limitations of these two imaging techniques, providing valuable insights for the scientific community.

Vortex rings, a mysterious and fascinating natural phenomenon, display breathtaking structures and behaviors in both air and electromagnetic waves. Imagine an air cannon that can shoot vortex rings, creating a perfect air vortex that travels gracefully through the air as if an invisible hand is sketching an elegant curve in the sky. This vortex phenomenon is not just a spectacle of physics but a masterpiece of nature.

Due to its excellent material properties and its adaptability to gallium nitride (GaN), AlYN has enormous potential for use in energy-efficient high-frequency and high-performance electronics for information and communications technology.

Aluminum yttrium nitride (AlYN) has attracted the interest of many research groups around the world due to its outstanding material properties. However, the growth of the material has been a major challenge. Until now, AlYN could only be deposited by magnetron sputtering.

Researchers at the Fraunhofer Institute for Applied Solid State Physics IAF have now succeeded in fabricating the new material using metal-organic chemical vapor deposition (MOCVD) technology, thus enabling the development of new, diverse applications.

Light technology is at the heart of many cutting-edge innovations, from high-speed internet to advanced medical imaging. However, transmitting light through challenging environments, such as turbulent atmospheres or deformed optical systems, has always posed a significant hurdle. These complexities can distort and disrupt the light field, making it difficult to achieve clear and reliable results. Scientists have long sought ways to overcome these limitations, and a new breakthrough may hold the key to advancing practical applications.

Key to winning a cricket match is tricking the other team’s batters—no small feat, as bowlers bowl cricket balls nearly 100 miles per hour. In recent years, a bowling technique that has become popular involves keeping the arm almost entirely horizontal during delivery, notably used by Sri Lankan stars Lasith Malinga and Matheesha Pathirana. The aerodynamics of such deliveries have perplexed sports physicists.

An international team of astronomers has reported the discovery of a new brown dwarf, which received designation TOI-2490 b. The newfound object is about 74 times more massive than Jupiter and orbits a sun-like star on a highly eccentric orbit. The finding was detailed in a paper published August 8 on the pre-print server arXiv.
