High-strength and ultra-tough whole spider silk fibers spun from transgenic silkworms

Posted by in categories: cyborgs, engineering, sustainability, transhumanism

Lightweight materials with super strength and toughness are highly sought after. Spider silk, a sustainable material, meets these requirements but faces challenges in commercialization due to scientific understanding of its spinning mechanism, technical complexities in the process, and engineering hurdles in low-cost mass production. Here, drawing inspiration from nylon and Kevlar, we propose a theory on the nature of toughness and strength, unveiling the basic structure of silk fibers. Using these theories, we successfully produce the first “localized” full-length spider silk fiber via transgenic silkworms, showcasing high tensile strength (1,299 MPa) and exceptional toughness (319 MJ/m3). This breakthrough overcomes scientific, technical, and engineering obstacles, paving the way for spider silk’s commercialization as a sustainable substitute for synthetic fibers. Moreover, our theories provide essential guidance for developing super materials.


Developing sustainable materials with high strength and ultra-toughness is vital for ecological civilization. Using transgenic silkworms, we have successfully produced the first full-length spider silk, overcoming the scientific challenge of understanding the essence of toughness and strength. The resulting bionic spider silk exhibits high strength (1,299 MPa) and ultra-toughness (319 MJ/m3), offering a potentially sustainable substitute for synthetic commercial fibers. This breakthrough provides valuable insights for the development of super materials, including those for a space elevator, driving the advancement of civilization.

Scientists discover neurons that act as brain ‘glue’ to recall memories

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

Scientists have discovered new insights into how our brain stores episodic memories—a type of long-term, conscious memory of a previous experience—that could be critical to the development of new neuroprosthetic devices to help patients with memory problems, like Alzheimer’s disease and dementia.

The new study—led by the University of Glasgow, in collaboration with the University of Birmingham and University of Erlangen—used special electrodes, implanted directly into the brains of epilepsy patients requiring surgery, to allow scientists to observe the activity of individual neurons in the hippocampus region of the brain.

The hippocampus is a challenging area to study, due to its location deep within the brain, yet this area is critical for our memory, acting as the librarian to the memory library in our brain.

This robotic exoskeleton can help runners sprint faster

Posted by in categories: cyborgs, robotics/AI, wearables

It encourages wearers to take more steps, covering distances more quickly than they could without it.

A wearable exoskeleton can help runners increase their speed by encouraging them to take more steps, allowing them to cover short distances more quickly.

While previous studies have focused on how wearable exoskeletons can help people reduce the energy they expend while running, the new study, published today in Science Robotics, examines how wearable robots can assist runners as they sprint.

A non-invasive way to turn a cockroach into a cyborg

Posted by in categories: cyborgs, life extension

A team of mechanical engineers at Nanyang Technological University in Singapore has found a way to electronically control cockroaches without injuring them. In their paper published in the journal npj Flexible Electronics, the group describes the new technology they used to remotely control the cockroaches and the benefits of doing so.

Prior research teams have created a variety of cyborg , but they all had one feature in common—they all involved attaching probes to the insect’s nervous system—procedures that led to damage to the insect, and likely some degree of pain.

Intel unveils Meteor Lake CPUs, features dedicated AI engine

Posted by in categories: cyborgs, mobile phones, robotics/AI, transhumanism

This processor is the first to be built on the Intel 4 (7nm) architecture.

Intel, the PC silicon giant, has recently made a significant announcement that’s set to revolutionize its mobile processor line. On Tuesday, at the Intel Innovation event, the company unveiled its highly anticipated Meteor Lake processors, now known as Core Ultra chips. This is after Intel decided to do away with the Core “i” designation in June 2023. It is slated for release on December 14, and laptops coming out in the first quarter of 2024 should start adopting the new chips. While this news is undoubtedly exciting for tech enthusiasts, it also raises important questions for consumers: Will Intel-powered Windows… More.

China aims to replicate human brain in bid to dominate global AI

Posted by in categories: cyborgs, governance, government, robotics/AI, surveillance, transhumanism

Aiming to be first in the world to have the most advanced forms of artificial intelligence while also maintaining control over more than a billion people, elite Chinese scientists and their government have turned to something new, and very old, for inspiration—the human brain.

Equipped with surveillance and visual processing capabilities modelled on human vision, the new “brain” will be more effective, less energy hungry, and will “improve governance,” its developers say. “We call it bionic retina computing,” Gao Wen, a leading artificial intelligence researcher, wrote in the paper “City Brain: Challenges and Solution.”

Exploring transhumanism

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

What do pacemakers, prosthetic limbs, Iron Man and flu vaccines all have in common? They are examples of an old idea that’s been gaining in significance in the last several decades: transhumanism. The word denotes a set of ideas relating to the increasing integration of humans with their technologies. At the heart of the transhuman conversation, however, lies the oldest question of all: What does it mean to be human?

When talking about transhumanism, it’s easy to get lost because the definition is imprecise. “Transhumanism” can refer to the Transhumanist (with a capital T) movement, which actively pursues a technologically enhanced future, or an amorphous body of ideas and technologies that are closing the bio-techno gap, such as a robotic exoskeleton that enhances the natural strength of the wearer.

At Arizona State University, a diverse set of researchers has been critically examining transhumanism since 2004.

Fiber from crustaceans, insects, mushrooms promotes digestion

Posted by in categories: biotech/medical, cyborgs, food

Digesting a crunchy critter starts with the audible grinding of its rigid protective covering — the exoskeleton. Unpalatable as it may sound, the hard cover might be good for the metabolism, according to a new study, in mice, from Washington University School of Medicine in St. Louis. The researchers, led by Steven Van Dyken, PhD, an assistant professor of pathology & immunology, found in mice that digesting chitin, an abundant dietary fiber in insect exoskeletons and also mushrooms and crustacean shells, engages the immune system. An active immune response was linked to less weight gain, reduced body fat and a resistance to obesity. “Obesity is an epidemic,” Van Dyken said. “What we put into our bodies has a profound effect on our physiology and on how we metabolize food. We’re investigating ways to counteract obesity based on what we learn about how the immune system is engaged by diet.”


Findings, in mice, suggest engaging immune system with such fiber to counteract obesity.

Oregon scientists are building a better bionic eye

Posted by in categories: biological, cyborgs, neuroscience, transhumanism

Serious vision loss affects millions of Americans each year, and biological strategies are still decades away from restoring eyesight lost to macular degeneration. But University of Oregon researchers are looking to create an electronic solution — a bionic eye — that could restore people’s sight. They’re tapping into the world of fractal structures that will allow a retinal implant and a human brain to communicate with each other.
