Researchers have developed a #fast #highresolution #microscope that enables them to #visualize #neuronalactivity within the #zebrafish #brain. Zebrafish #Danio #rerio (#Danionidae) are popular aquarium fish that are easy to keep and breed. For these same reasons, they also serve as suitable #scientificmodel organisms. A particular advantage for science is that the developing #embryos and #larvae are initially #transparent, allowing for the observation of various developmental biological processes. The development of the #nervoussystem, including the brain, is of particular interest. However, current research focuses not only on the brain's ontogenetic development but also on its detailed anatomy and functional mechanisms. Neurons communicate with one another via #electricalimpulses. Since vertebrate brains are generally highly capable of multitasking, constantly processing multiple sensory inputs simultaneously, electrical impulses occur in different regions of the brain at the same time. Visualizing this activity has previously required complex measurement methods. Z. Wang et al. (2026) have developed a #novelmicroscope capable of optically capturing and displaying brain-wide neuronal activity within the zebrafish brain. This opens up entirely new research possibilities for a wide range of neurobiological questions. To achieve this, researchers from the MIT team modified a #lightsheetmicroscope. By using a #laserbeam and sequentially imaging #multiplelayers, they generate #threedimensional #images of a large #volume. Since neural networks operate extremely rapidly, often taking only a few milliseconds, previous methods such as #calciumimaging were too slow. To create a high-speed microscope, the authors increased the camera's image #acquisitionrate. They also employed "#remoterefocusing" to boost the microscope's #scanningspeed. This enabled the researchers to scan the zebrafish brain 200 times per second. They introduced a #voltageindicator named #Positron2-Kv into the fish larvae by genetically modifying specific neurons; this provided sufficient resolution to visualize brain voltage patterns at high speed. Additionally, ultraviolet light was used as an extra stimulus. The researchers aim to further develop their technology to eventually correlate brain activity with states of #consciousness and #behaviors. © #Stefan F.

Researchers have discovered #geoglyphs in the #Amazonregion using #LiDAR #technology. These geoglyphs cover approximately 50 hectares and appear to belong to a previously #unknownculture. LiDAR (#LightDetectionandRanging) technology allows researchers to #visualize #structures on the #groundsurface from the distance of an #aircraft, even when they are obscured by dense vegetation that would otherwise remain hidden. This is achieved by emitting invisible #laserbeams in the infrared range, the reflection of which is then analyzed. This process produces millimeter-precise images of the landscape under investigation. By applying this technology in the Amazon region, M. Pärssinen et al. (2026) discovered geoglyphs in the southwestern Amazon area. These geoglyphs exhibit symmetrical forms and cover an area of approximately half a million square meters. The researchers thus discovered about 400 previously unknown structures in present-day #Brazil, which they attribute to a formerly unknown civilization. In their research article published in the #journalNature, they refer to this culture as the #Aquiry #culture. The structures apparently served ritual and political purposes. The population lived by clearing land through #slashandburn #agriculture and by cultivating crops such as #maize and #squash, as well as #fruittrees like peach palms. The area was settled over a period of approximately 1,500 years, between 600 BC and 800 AD. The #archaeologists estimate that around 3 million people may have lived in the Aquiry area. Considering the entire Amazonas region and the other ancient cultures inhabiting it besides the Aquiry, the total population could have been in the tens of millions. Like the Aquiry, these cultures must have possessed highly developed skills in land cultivation, as building monumental structures in the rainforest requires logistical, geometric, and organizational expertise. The new findings demonstrate that the Amazon region has apparently been shaped by #historicalhumanactivity to a significantly greater extent than previously assumed. © #StefanF.Wirth, July 2026, Berlin Please support my science communication efforts with a small donation; it is an important part of my meager income: https://t.co/4nN4eRHB6I Reference: M.
