Brain connectivity found to be disrupted in schizophrenia

Posted by in categories: biotech/medical, health, mathematics, neuroscience

Schizophrenia, a neurodevelopmental disorder that features psychosis among its symptoms, is thought to arise from disorganization in brain connectivity and functional integration. Now, a recent study in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging, finds differences in functional brain connectivity in people with and without psychosis and schizophrenia that could help researchers understand the neural underpinnings of this disease.

The brain’s cortex is organized in a hierarchical fashion, anchored by the sensorimotor cortex at one end and by multimodal association areas at the other, with the task of integrating incoming sensory information with internal and external sensory signals. The loss of executive control in schizophrenia may stem from disruption of this hierarchical signaling.

Alexander Holmes, a Ph.D. candidate at Monash University who led the study, said, “We used brain imaging and novel mathematical techniques to investigate the hierarchical organization of the brains of individuals with early psychosis and established schizophrenia. This organization is important for brain health, as it regulates how we can effectively respond to and process stimuli from the external world.”

Single-cell epigenomic reconstruction of developmental trajectories from pluripotency in human neural organoid systems

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

The mechanisms underlying human cell diversity are unclear. Here the authors provide a single-cell epigenome map of human neural organoid development and dissect how epigenetic changes control cell fate specification from pluripotency to distinct cerebral and retina neural types.

Engineers create first skin tissue compatible with humanoid robots

Posted by in categories: biotech/medical, robotics/AI

Japanese researchers have developed a novel technique to attach engineered skin tissue to humanoid robots.

Robotic platforms may benefit from enhanced mobility, embedded sensing capabilities, self-healing capabilities, and a more realistic appearance.

The innovation was made possible by mimicking skin-ligament structures and using V-shaped perforations in a robot face.

Dissecting the epigenetic regulation of human brain organoid development in single cells

Posted by in categories: genetics, neuroscience

We present a developmental atlas that offers insight into sequential epigenetic changes underlying early human brain development modeled in organoids, which reconstructs the differentiation trajectories of all major CNS regions. It shows that epigenetic regulation via the installation of activating histone marks precedes activation of groups of neuronal genes.

New organoid culture method can verify human toxicity of nanomaterials

Posted by in categories: biotech/medical, nanotechnology

The organoids were treated with zinc oxide nanoparticles (ZnO NPs), which are a liver toxic material, and nontoxic gold nanoparticles (AuNPs). The comparison showed that the toxicity of each material could be accurately observed, in contrast to the conventional method.

Ahruem Baek, a senior researcher at KRISS, said, “Based on our results, we will establish standard nanomaterial and nanomedicine safety assessment procedures using organoids, contributing to the advancement of Korea’s nano-industry.”

The results from this study may allow for rapid and accurate safety assessment of nanomaterials and nanomedicine using organoids, contributing to the safe utilization of nanomaterials in various strategic technical fields.

Quantum annealer improves understanding of quantum many-body systems

Posted by in categories: particle physics, quantum physics, supercomputing

The result is a significant advancement in the field, showcasing the practical applicability of quantum computing in solving complex material science problems. Furthermore, the researchers discovered factors that can improve the durability and energy efficiency of quantum memory devices. The findings have been published in Nature Communications.

In the early 1980s, Richard Feynman asked whether it was possible to model nature accurately using a classical computer. His answer was: no. The world consists of fundamental particles, described by the principles of quantum physics. The exponential growth of the variables that must be included in the calculations pushes even the most powerful supercomputers to their limits. Instead, Feynman suggested using a computer that was itself made up of . With his vision, Feynman is considered by many to be the Father of Quantum Computing.

Scientists at Forschungszentrum Jülich, together with colleagues from Slovenian institutions, have now shown that this vision can actually be put into practice. The application they are looking at is a so-called many-body system. Such systems describe the behavior of a large number of particles that interact with each other.

First Nigerian set to fly to space for free

Posted by in category: space travel

Expensive, risky and elite — that’s space travel in a nutshell ever since Yuri Gagarin became the first human to be sent to space 63 years ago. Till now, less than 700 astronauts have reached space altitude and a majority among them have been from just three countries. Even commercial space flights remain exclusive to the few who can afford them.

But not anymore. Giving regular folks from around the world a chance to become astronauts and participate in space science, US-based Space Exploration and Research Agency (SERA) has partnered with Jeff Bezos’ Blue Origin to develop what they call “a human spaceflight programme for citizens of all nations”. The cost will be borne by SERA, and co-founders Sam Hutchison and Joshua Skurla say they might even be tapping talent from India for their programme.

In line with this mission to make space accessible, SERA has just signed an agreement to send the first Nigerian to space. In June 2022, Victor Hespanha, a 28-year-old civil engineer from Brazil, was selected to travel to space onboard Blue Origin’s New Shepard Rocket (NS-22). He was only the second Brazilian astronaut, and soon became a national hero.
