The realization of a continuous time crystal based on a photonic metamaterial

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

A time crystal, as originally proposed in 2012, is a new state of matter in which the particles are in continuous oscillatory motion. Time crystals break time-translation symmetry. Discrete time crystals do so by oscillating under the influence of a periodic external parametric force, and this type of time crystal has been demonstrated in trapped ions, atoms and spin systems.

Continuous time crystals are more interesting and arguably more important, as they exhibit continuous time-translation symmetry but can spontaneously enter a regime of periodic motion, induced by a vanishingly small perturbation. It is now understood that this state is only possible in an open system, and a continuous quantum-time-crystal state has recently been observed in a quantum system of ultracold atoms inside an optical cavity illuminated with light.

In a paper published in Nature Physics, researchers at University of Southampton in the U.K. showed that a classical metamaterial nanostructure can be driven to a state that exhibits the same key characteristics of a continuous time crystal.

Study presents large brain-like neural networks for AI

Posted by in categories: augmented reality, biological, mobile phones, robotics/AI, virtual reality, wearables

In a new study in Nature Machine Intelligence, researchers Bojian Yin and Sander Bohté from the HBP partner Dutch National Research Institute for Mathematics and Computer Science (CWI) demonstrate a significant step towards artificial intelligence that can be used in local devices like smartphones and in VR-like applications, while protecting privacy.

They show how brain-like neurons combined with novel learning methods enable training fast and energy-efficient spiking on a large scale. Potential applications range from wearable AI to and Augmented Reality.

While modern artificial neural networks are the backbone of the current AI revolution, they are only loosely inspired by networks of real, biological neurons such as our brain. The brain however is a much larger network, much more energy-efficient, and can respond ultra-fast when triggered by external events. Spiking neural networks are special types of neural networks that more closely mimic the working of biological neurons: the neurons of our nervous system communicate by exchanging electrical pulses, and they do so only sparingly.

New self-repairing bio-shoe concept unveiled

Posted by in categories: biological, materials

Year 2013 😗😁


Shamees Aden, a British designer and scientist, has come up with a concept for a pair of self-repairing shoes of synthetic protocell materials.

Protocells are molecules that on their own are not alive, but when used with other types of protocells can mimic the properties of living organisms. They react to heat, light and pressure like live cells.

AI identifies three new antiaging senolytic candidates

Posted by in categories: biotech/medical, chemistry, life extension, robotics/AI

New research by biotech Integrated Biosciences and scientists from MIT and the Broad Institute of MIT and Harvard has demonstrated the potential of AI in discovering novel senolytic compounds.

Longevity. Technology: Senolytics are small molecules that suppress age-related processes such as fibrosis, inflammation and cancer. They target senescent cells – the so-called ‘zombie’ cells that are no longer dividing, emit toxic chemicals and are a hallmark of aging. Senescent cells have been linked to various age-related diseases, including cancer, cardiovascular disease, diabetes and Alzheimer’s disease, but senolytic compounds can tackle them by selectively inducing apoptosis or programmed cell death in these zombie cells. This new research reduced the number of senescent cells and lowered the expression of senescence-associated genes in aged mice, results which, the authors say “underscore the promise of leveraging deep learning to discover senotherapeutics[1].

The AI-guided screening of more than 800,000 compounds led to the identification of three drug candidates, which, when compared with senolytics currently under investigation, were found to have comparable efficacy and superior medicinal chemistry properties [1].

Researchers engineer solution to extend cellular lifespan and slow aging

Posted by in categories: bioengineering, biotech/medical, genetics, life extension

Human lifespan is intricately connected to the aging process of individual cells, and this means that scientists have spent decades trying to unravel the mysteries of cellular aging and exploring methods to slow down the ticking of the aging clock.

Longevity. Technology: In 2020, a group of researchers from the University of California San Diego identified two distinct mechanisms of cellular aging and genetically manipulated them to extend cell lifespan [1]. Now, their research has progressed to employ synthetic biology and gene circuits to delay the deterioration associated with cellular aging [2]. The team’s innovative approach could revolutionize scientific methods of aging prevention and contribute to reprogramming aging pathways in various human cell types.

Publishing in Science, the researchers describe how cells in yeast, plants, animals and humans all contain gene regulatory circuits responsible for several physiological functions, including aging. These gene circuits, akin to electric circuits controlling household devices, can operate in different ways, and the UC San Diego team discovered that cells don’t necessarily age the same way – it all depends on their genetic material and environment. The researchers found that cells can age either through DNA stability decline or mitochondrial decline.
