Physicists experimentally observe topological defects in glasses for the first time

Posted by in categories: biological, mathematics, particle physics, space

The amorphous state of matter is the most abundant form of visible matter in the universe, and includes all structurally disordered systems, such as biological cells or essential materials like glass and polymers.

An is a solid whose molecules and atoms form disordered structures, meaning that they do not occupy regular, well-defined positions in space.

This is the opposite of what happens in crystals, whose ordered structure facilitates their , as well as the identification of those “defects,” which practically control the physical properties of crystals, such as their plastic yielding and melting, or the way an electric current propagates through them.

Researchers Have Found a Way to Help Erase Bad Memories

Posted by in category: neuroscience

Being able to erase bad memories and traumatic flashbacks could help in the treatment of a host of different mental health issues, and scientists have found a promising new approach to do just this: weakening negative memories by reactivating positive ones.

In an experiment covering several days, an international team of researchers asked 37 participants to associate random words with negative images, before attempting to reprogram half of those associations and ‘interfere’ with the bad memories.

“We found that this procedure weakened the recall of aversive memories and also increased involuntary intrusions of positive memories,” write the researchers in their published paper.

AI comes down from the cloud as chips get smarter

Posted by in categories: robotics/AI, transportation

Artificial intelligence is moving from data centers to “the edge” as computer makers build the technology into laptops, robots, cars and more devices closer to home.

The Consumer Electronics Show (CES) gadget extravaganza that closed Friday was rife with PCs and other devices touting AI chips, making them more capable than ever and untethering them from the cloud.

Attention-grabbing stars included “AI PCs,” personal computers boasting chips that promised a level of performance once limited to muscular data centers.

A New Class of Cosmic X-ray Sources discovered

Posted by in category: biotech/medical

An international team of astronomers, led by researchers from the Astronomical Observatory of the University of Warsaw, have identified a new class of cosmic X-ray sources. The findings have been published in The Astrophysical Journal Letters.

Most people encounter X-rays during medical visits where they are used to create images of bones or diagnose lung conditions. These X-rays are generated using artificial sources.

However, not everyone knows that celestial objects can also emit X-ray radiation. “Some cosmic phenomena produce X-rays naturally,” explains Dr. Przemek Mróz, the lead author of the study. “For example, X-rays may be produced by a hot gas falling onto compact objects like white dwarfs, neutron stars, or black holes. X-rays can also be generated by decelerating charged particles, such as electrons.”

LLMs are becoming more Brain-like as they advance, researchers discover

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

Large language models (LLMs), the most renowned of which is ChatGPT, have become increasingly better at processing and generating human language over the past few years. The extent to which these models emulate the neural processes supporting language processing by the human brain, however, has yet to be fully elucidated.

Researchers at Columbia University and Feinstein Institutes for Medical Research Northwell Health recently carried out a study investigating the similarities between LLM representations on neural responses. Their findings, published in Nature Machine Intelligence, suggest that as LLMs become more advanced, they do not only perform better, but they also become more brain-like.

“Our original inspiration for this paper came from the recent explosion in the landscape of LLMs and neuro-AI research,” Gavin Mischler, first author of the paper, told Tech Xplore.

‘Their capacity to emulate human language and thought is immensely powerful’: Far from ending the world, AI systems might actually save it

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

Over the last few years, artificial intelligence (AI) has been firmly in the world’s spotlight, and the rapidly advancing technology can often be a source of anxiety and even fear in some cases. But the evolution of AI doesn’t have to be an inherently scary thing — and there are plenty of ways that this emerging technology can be used for the benefit of humanity.

Writing in “AI for Good” (Wiley, 2024), Juan M. Lavista Ferres and William B. Weeks, both senior directors at Microsoft’s AI for Good Research Lab, reveal how beneficial AI is being used in dozens of projects across the world today. They explain how AI can improve society by, for example, being used in sustainability projects like using satellites to monitor whales from space, or by mapping glacial lakes. AI can also be used in the wake of natural disasters, like the devastating 2023 earthquake in Turkey, or for social good, like curbing the proliferation of misinformation online. In addition, there are significant health benefits to reap from AI, including studying the long-term effects of COVID-19, using AI to manage pancreatic cysts or detecting leprosy in vulnerable populations.

In this excerpt, the authors detail the recent rise of large language models (LLMs) such as ChatGPT or Claude 3 and how they have grown to become prominent in today’s AI landscape. They also discuss how these systems are already making a significant beneficial impact on the world.

An integrative data-driven model simulating C. elegans brain, body and environment interactions

Posted by in categories: information science, robotics/AI

Our neural network model of C. elegans contained 136 neurons that participated in sensory and locomotion functions, as indicated by published studies24,27,28,29,30,31. To construct this model, we first collected the necessary data including neural morphology, ion channel models, electrophysiology of single neurons, connectome, connection models and network activities (Fig. 2a). Next, we constructed the individual neuron models and their connections (Fig. 2b). At this stage, the biophysically detailed model was only structurally accurate (Fig. 2c), without network-level realistic dynamics. Finally, we optimized the weights and polarities of the connections to obtain a model that reflected network-level realistic dynamics (Fig. 2d). An overview of the model construction is shown in Fig. 2.

To achieve a high level of biophysical and morphological realism in our model, we used multicompartment models to represent individual neurons. The morphologies of neuron models were constructed on the basis of published morphological data9,32. Soma and neurite sections were further divided into several segments, where each segment was less than 2 μm in length. We integrated 14 established classes of ion channels (Supplementary Tables 1 and 2)33 in neuron models and tuned the passive parameters and ion channel conductance densities for each neuron model using an optimization algorithm34. This tuning was done to accurately reproduce the electrophysiological recordings obtained from patch-clamp experiments35,36,37,38 at the single-neuron level. Based on the few available electrophysiological data, we digitally reconstructed models of five representative neurons: AWC, AIY, AVA, RIM and VD5.

Scientists mapped the genome of a shark that can live 400 years. It could unlock new secrets to longevity

DNA that can repair DNA similar to Digital Error Correction!

This could make human live longer!


Before the researchers sequenced the Greenland shark’s genome, only about 10 genomes were available for all elasmobranchs — a subclass of fish including sharks, rays and skates — said Dr. Nicole Phillips, an associate professor of ecology and organismal biology at the University of Southern Mississippi in Hattiesburg. Phillips was not involved in the research conducted by Hoffman, Sahm and their team.
