Offshore wind firm to work with researchers on recycling glass fibers to tackle blade waste

Posted by in category: sustainability

According to the university, the system focuses on the “thermal recovery and post-treatment of glass fibres” from glass-reinforced polymer composite scrap, with the end result “near-virgin quality glass fibres.” The idea is that, using this system, the composite waste could be re-used.


The aim is to scale-up and commercialize a process developed by team at the University of Strathclyde, in Scotland.

Scientists Develop Truly Biodegradable Plastics

Posted by in category: sustainability

While biodegradable plastics have been touted as a solution to plastic pollution, in practice they don’t work as advertised.

“Biodegradability does not equal compostability,” Ting Xu, study coauthor and UC Berkeley polymer scientist, told Science News.

But by studying nature, Xu and her team have developed a process that actually breaks down biodegradable plastics with just heat and water in a period of weeks. The results, published in Nature on Wednesday, could be game-changing for the plastic pollution problem.

Synthetic gelatin-like material mimics lobster underbelly’s stretch and strength

Posted by in category: materials

**A lobster’s underbelly is lined with a thin, translucent membrane that is both stretchy and surprisingly tough.** This marine under-armor, as MIT engineers reported in 2019, is made from the toughest known hydrogel in nature, which also happens to be highly flexible. This combination of strength and stretch helps shield a lobster as it scrabbles across the seafloor, while also allowing it to flex back and forth to swim.

This combination of strength and stretch helps shield a lobster as it scrabbles across the seafloor, while also allowing it to flex back and forth to swim.

Now a separate MIT team has fabricated a hydrogel-based material that mimics the structure of the lobster’s underbelly. The researchers ran the material through a battery of stretch and impact tests, and showed that, similar to the lobster underbelly, the is remarkably “fatigue-resistant,” able to withstand repeated stretches and strains without tearing.

China rolls out Long March 5B rocket for space station launch

Posted by in category: space travel

HELSINKI — China is set to launch the first module for its own space station next week after rolling out a Long March 5B rocket at Wenchang spaceport late Thursday.

The 53.7-meter-long Long March 5B is now expected to launch the 22-ton Tianhe space station core module around April 29, although authorities have not officially released a launch time.

The launch will mark the beginning of an intense construction phase for the three-module space station. China plans 11 major launches of modules, cargo and crewed spacecraft across 2021–22.

Breakthrough Sets Stage for Biotech to Generate 1 Billion Vaccine Doses in Less Than a Month

Posted by in categories: biotech/medical, transportation

In February, the researchers introduced a new biomanufacturing platform that can quickly make shelf-stable vaccines at the point of care, ensuring they will not go to waste due to errors in transportation or storage. In its new study, the team discovered that enriching cell-free extracts with cellular membranes — the components needed to made conjugate vaccines — vastly increased yields of its freeze-dried platform.

The work sets the stage to rapidly make medicines that address rising antibiotic-resistant bacteria as well as new viruses at 40000 doses per liter per day, costing about $1 per dose. At that rate, the team could use a 1000-liter reactor (about the size of a large garden waste bag) to generate 40 million doses per day, reaching 1 billion doses in less than a month.

Martin Rees and Frederick Lamb on humanity’s fate

Posted by in categories: alien life, cybercrime/malcode, evolution, military

Rees explained how his astronomy background meshes with his concern for humanity’s fate:

People often ask does being an astronomer have any effect on one’s attitude toward these things. I think it does in a way, because it makes us aware of the long-range future. We’re aware that it’s taken about 4 billion years for life to evolve from simple beginnings to our biosphere of which we are a part, but we also know that the sun is less than halfway through its life and the universe may go on forever. So we are not the culmination of evolution. Post-humans are going to have far longer to evolve. We can’t conceive what they’d be like, but if life is a rarity in the universe, then, of course, the stakes are very high if we snuff things out this century.

Bottom line: From nuclear weapons to biowarfare to cyberattacks, humanity has much to overcome. Martin Rees and Frederick Lamb discuss the obstacles we face as we look forward to humanity’s future on Earth.

Making Sense Podcast Special Episode: Engineering the Apocalypse

Posted by in categories: bioengineering, biological, biotech/medical, existential risks, finance, media & arts, robotics/AI, terrorism

In this nearly 4-hour SPECIAL EPISODE, Rob Reid delivers a 100-minute monologue (broken up into 4 segments, and interleaved with discussions with Sam) about the looming danger of a man-made pandemic, caused by an artificially-modified pathogen. The risk of this occurring is far higher and nearer-term than almost anyone realizes.

Rob explains the science and motivations that could produce such a catastrophe and explores the steps that society must start taking today to prevent it. These measures are concrete, affordable, and scientifically fascinating—and almost all of them are applicable to future, natural pandemics as well. So if we take most of them, the odds of a future Covid-like outbreak would plummet—a priceless collateral benefit.

Rob Reid is a podcaster, author, and tech investor, and was a long-time tech entrepreneur. His After On podcast features conversations with world-class thinkers, founders, and scientists on topics including synthetic biology, super-AI risk, Fermi’s paradox, robotics, archaeology, and lone-wolf terrorism. Science fiction novels that Rob has written for Random House include The New York Times bestseller Year Zero, and the AI thriller After On. As an investor, Rob is Managing Director at Resilience Reserve, a multi-phase venture capital fund. He co-founded Resilience with Chris Anderson, who runs the TED Conference and has a long track record as both an entrepreneur and an investor. In his own entrepreneurial career, Rob founded and ran Listen.com, the company that created the Rhapsody music service. Earlier, Rob studied Arabic and geopolitics at both undergraduate and graduate levels at Stanford, and was a Fulbright Fellow in Cairo. You can find him at www.after-on.

A new pathway to stable, low-cost, flexible electronics

Posted by in categories: materials, mobile phones

Imagine a foldable smartphone or a rollable tablet device that is powerful, reliable and, perhaps most importantly, affordable.

New research directed by Wake Forest University scientists and published today in the journal Nature Communications has led to a method for both pinpointing and eliminating the sources of instability in the materials and devices used to create such applications.

“In this work, we introduced a strategy that provides a reliable tool for identifying with high accuracy the environmental and operational device degradation pathways and subsequently eliminating the main sources of instabilities to achieve stable devices,” said lead author Hamna Iqbal, a who worked closely with Professor of Physics Oana Jurchescu on the research.
