Harvard and Google Neuroscience Breakthrough: Intricately Detailed 1,400 Terabyte 3D Brain Map

Posted by in categories: biotech/medical, computing, neuroscience

A collaborative effort between Harvard and Google has led to a breakthrough in brain science, producing an extensive 3D map of a tiny segment of human brain, revealing complex neural interactions and laying the groundwork for mapping an entire mouse brain.

A cubic millimeter of brain tissue may not sound like much. But considering that tiny square contains 57,000 cells, 230 millimeters of blood vessels, and 150 million synapses, all amounting to 1,400 terabytes of data, Harvard and Google researchers have just accomplished something enormous.

A Harvard team led by Jeff Lichtman, the Jeremy R. Knowles Professor of Molecular and Cellular Biology and newly appointed dean of science, has co-created with Google researchers the largest synaptic-resolution, 3D reconstruction of a piece of human brain to date, showing in vivid detail each cell and its web of neural connections in a piece of human temporal cortex about half the size of a rice grain.

Lunar Gateway’s Revolutionary Powerhouse: Unveiling High-Tech Power and Propulsion Element

Posted by in categories: solar power, space travel

NASA ’s upcoming Gateway space station, set to orbit the Moon, will rely heavily on its Power and Propulsion Element (PPE) for energy and maintaining its orbit. Currently under development with Maxar Technologies, the PPE uses solar electric propulsion to efficiently power the station. This system, designed to significantly reduce the need for propellant, will be integrated with Gateway’s habitation module and launched to support deep space exploration and future Artemis missions to Mars.

As astronauts live and work on Gateway to enable sustained exploration and research in deep space, their efforts will be made possible by Gateway’s Power and Propulsion Element (PPE). A foundational component of the lunar outpost and the most powerful solar electric spacecraft ever flown, PPE will provide Gateway with power and allow it to maintain its unique orbit around the Moon.

XMM-Newton’s Stunning X-Ray Vision Unmasks Mysterious Cosmic Structure

Posted by in category: cosmology

New observations reveal that X-ray emissions from the Cloverleaf odd radio circle are linked to merging galaxy groups, offering new insights into these mysterious cosmic structures.

Astronomers have discovered enormous circular radio features of unknown origin around some galaxies. Now, new observations of one dubbed the Cloverleaf suggest it was created by clashing groups of galaxies.

Studying these structures, collectively called ORCs (odd radio circles), in a different kind of light offered scientists a chance to probe everything from supersonic shock waves to black hole behavior.

Quantum Mystery Solved — Scientists Shed Light on Perplexing High-Temperature Superconductors

Posted by in categories: biotech/medical, quantum physics

Flatiron Institute senior research scientist Shiwei Zhang and his team have utilized the Hubbard model to computationally re-create key features of the superconductivity in materials called cuprates that have puzzled scientists for decades.

Superfast hovering trains, long-distance power transmission without energy loss, and quicker MRI scanners — all these incredible technological innovations could be within reach if we could develop a material that conducts electricity without any resistance, or “superconducts,” at approximately room temperature.

In a paper recently published in the journal Science, researchers report a breakthrough in our understanding of the origins of superconductivity at relatively high (though still frigid) temperatures. The findings concern a class of superconductors that has puzzled scientists since 1986, called ‘cuprates.’

Revolutionizing Photonics: Lithium Tantalate Powers Next-Gen Optical Circuits

Posted by in category: computing

New photonic integrated circuit technology based on lithium tantalate improves cost-efficiency and scalability, making significant advancements in optical communications and computing.

Optical communications and computing systems have been revolutionized by the rapid advancement in photonic integrated circuits (PICs), which combine multiple optical devices and functionalities on a single chip.

For decades, silicon-based PICs have dominated the field due to their cost-effectiveness and their integration with existing semiconductor manufacturing technologies, despite their limitations with regard to their electro-optical modulation bandwidth. Nevertheless, silicon-on-insulator optical transceiver chips were successfully commercialized, driving information traffic through millions of glass fibers in modern data centers.

Engineers develop innovative microbiome analysis software tools

Posted by in categories: biotech/medical, innovation

Since the first microbial genome was sequenced in 1995, scientists have reconstructed the genomic makeup of hundreds of thousands of microorganisms and have even devised methods to take a census of bacterial communities on the skin, in the gut, or in soil, water and elsewhere based on bulk samples, leading to the emergence of a relatively new field of study known as metagenomics.

MRI enables detection of light deep inside the brain

Posted by in categories: biotech/medical, neuroscience

Engineers at MIT have developed a groundbreaking method for detecting bioluminescent light within the brain.

By modifying the brain’s blood vessels to express a specific protein, they induced dilation in response to light exposure.

The approach enabled researchers to visualize the dilation using magnetic resonance imaging (MRI), facilitating precise localization of light sources within the brain.
