Researchers from the University of California, Berkeley have developed cutting-edge nanoscale optical imaging techniques to provide unprecedented insights into the ultrafast carrier dynamics in advanced materials. Two recent studies, published in Advanced Materials (“Transient Nanoscopy of Exciton Dynamics in 2D Transition Metal Dichalcogenides”) and ACS Photonics (“Near-Field Nanoimaging of Phases and Carrier Dynamics in Vanadium Dioxide Nanobeams”), showcase significant progress in understanding the carrier behaviors in two-dimensional and phase-change materials, with implications for next-generation electronic and optoelectronic devices.

The research team, led by Prof. Costas P. Grigoropoulos, Dr. Jingang Li, and graduate student Rundi Yang, employed a novel near-field transient nanoscopy technique to probe the behavior of materials at the nanoscale with both high spatial and temporal resolution. This approach overcomes the limitations of traditional optical methods, allowing researchers to directly visualize and analyze phenomena that were previously difficult to observe.

NASA astronaut Donald Pettit took a photo of stars from the International Space Station in 2003. It’s no longer “possible” to take it now.

The ancient creature’s guts bring ancient history to life.

The ocean was discovered 430 miles deep into the Earth’s mantle, which was usually thought to be a hot rocky layer devoid of water.

The pulse of increased seismicity starting at around 10 a.m. Wednesday and another pulse starting at around 4 a.m. today. As of 8:45 a.m., Hawaiian Volcano Observatory officials reported the pulse was still ongoing.

According to Hawaiian Volcano Observatory, the seismicity and elevated ground deformation rates suggests magma may be slowly moving out of the summit storage region. Additional seismic pulses or swarms may occur with little or no warning and result in either continued intrusion of magma or eruption of lava.

In a recent study published in Neuron, researchers discovered that microglia, the brain’s immune cells, use tunneling nanotubes…

Scheiblich et al. uncover a novel mechanism by which microglia use tunneling nanotubes to connect with α-syn-or tau-burdened neurons, enabling transfer of these proteins to microglia for clearance. Microglia donate mitochondria to restore neuronal health, shedding light on new therapeutic strategies for neurodegenerative diseases.

Nano-MIND Technology for Wireless Control of Brain Circuits with Potential to Modulate Emotions, Social Behaviors, and Appetite.

Researchers at the Center for Nanomedicine within the Institute for Basic Science (IBS) and Yonsei University in South Korea have unveiled a groundbreaking technology that can manipulate specific regions of the brain using magnetic fields, potentially unlocking the secrets of high-level brain functions such as cognition, emotion, and motivation. The team has developed the world’s first Nano-MIND (Magnetogenetic Interface for NeuroDynamics) technology, which allows for wireless, remote, and precise modulation of specific deep brain neural circuits using magnetism.

The human brain contains over 100 billion neurons interconnected in a complex network. Controlling the neural circuits is crucial for understanding higher brain functions like cognition, emotion, and social behavior, as well as identifying the causes of various brain disorders. Novel technology to control brain functions also has implications for advancing brain-computer interfaces (BCIs), such as those being developed by Neuralink, which aim to enable control of external devices through thought alone.
