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.

Study confirms age of oldest fossil human footprints in North America

Posted by in category: futurism

New research from a team including a Lawrence Livermore National Laboratory scientist reaffirms that human footprints found in White Sands National Park, New Mexico, date to the Last Glacial Maximum, placing humans in North America thousands of years earlier than once thought. Explore the role of radiocarbon dating of pollen in the discovery:

Treatment strategies for stage IV lung cancer

Posted by in category: biotech/medical

Paul Bunn, MD, University of Colorado Cancer Center, Aurora, CO, discusses the survival rates of patients with stage IV lung cancer, which remain suboptimal. For patients who have a high PD-L1 tumor proportion score (TPS), approximately a third of patients survive 5 years after initial diagnosis, and further statistical analysis is required to assess whether co-morbidities contribute to patient mortality after the 5 year mark. Despite the lack of available therapies for patients with late stage lung cancer, Prof. Bunn highlights treatment options for early stage lung cancer including immunotherapy and tyrosine kinase inhibitors (TKIs) for patients with driver mutations. This interview took place at the 2022 Targeted Therapies of Lung Cancer Meeting (TTLC 2022).

Tesla is building something called ‘Giga Water Loop’

Posted by in category: sustainability

Tesla is planning to build something called “Giga Water Loop” just outside of Gigafactory Texas in Austin.

But we are not sure what it is.

Gigafatory Texas is arguably Tesla’s most ambitious manufacturing project to date, and that’s saying a lot because the company has many ambitious manufacturing projects.

AIs accurately predicted path of Hurricane Lee a week out

Posted by in categories: climatology, physics, robotics/AI, supercomputing

To make its weather predictions, it analyzes 60 million daily observations from satellite, aircraft, and ground-based reports, using what we know about atmospheric physics to determine what the weather is likely to be like across the globe over the next 15 days.

This can literally save lives — if people know in advance that hurricanes or winter storms are heading their way, they can take action to prepare — but because the model is so complex, it must be run on a supercomputer over the course of several hours, which also makes it expensive.

The AIs: AI-based weather forecasting models are starting to catch up with traditional ones, like the European Model.
