Genetic engineering sheds light on ancient evolutionary questions

Posted by in categories: bioengineering, climatology, genetics, sustainability

Cyanobacteria are single-celled organisms that derive energy from light, using photosynthesis to convert atmospheric carbon dioxide (CO2) and liquid water (H2O) into breathable oxygen and the carbon-based molecules like proteins that make up their cells. Cyanobacteria were the first organisms to perform photosynthesis in the history of Earth, and were responsible for flooding the early Earth with oxygen, thus significantly influencing how life evolved.

Geological measurements suggest that the atmosphere of the early Earth—over three billion years ago—was likely rich in CO2, far higher than current levels caused by , meaning that ancient had plenty to “eat.”

But over Earth’s multi-billion-year history, atmospheric CO2 concentrations have decreased, and so to survive, these bacteria needed to evolve new strategies to extract CO2. Modern cyanobacteria thus look quite different from their ancient ancestors, and possess a complex, fragile set of structures called a CO2-concentrating mechanism (CCM) to compensate for lower concentrations of CO2.

World’s first semi-submersible floating offshore wind farm blows past expectations

Posted by in category: sustainability

WindFloat Atlantic – the world’s first semi-submersible floating offshore wind farm – has been online for two years, and it’s far exceeding power output expectations.

The 25 megawatt (MW) WindFloat Atlantic project ended 2022 with an electricity production of 78 gigawatt hours (GWh) – 5% more output than its first year. It supplies power to more than 25,000 households and avoids 33,000 tonnes of carbon dioxide. Its annual availability was between 93–94%.

The offshore wind farm sits 20 km off the coast of Portugal in the municipality of Viana do Castelo, north of Porto. It’s made up of three 8.4 MW Vestas wind turbines that sit on semi-submersible, three-column floating platforms anchored by chains to the seabed. A 20 km long (12.4 mile long) cable connects it to an onshore substation.

Ultrafast water permeation through nanochannels with a densely fluorous interior surface

Posted by in categories: innovation, sustainability

The key innovation in this new desalination technology is fluorine, a hydrophobic element that that’s long been prized for its desire to be left alone. It’s no accident that fluorine is a key ingredient in Teflon, which is used on non-stick pans to keep fried eggs from sticking and inside pipes to make fluids flow more efficiently. At the nanoscopic level, fluorine repels negatively charged ions, including the chlorine in salt (NaCl). Its electric properties also break down clumps of water molecules that can keep the liquid from flowing as freely as possible. -(IE)

-Desalination is something people need to consider with rising sea levels and changing weather patterns, like drought.


Oligoamide nanoring-based fluorous nanochannels in bilayer membranes enable ultrafast water permeation and desalination.

IBM AI Helps NASA Researchers Mine Earth Data

Posted by in categories: climatology, robotics/AI, sustainability

NASA has a massive amount of data and it receives more every day. While some of the data is processed immediately, much of the data is archived to be processed later, sometimes years later. This situation needs to change if researchers are to utilize the data to investigate critical issues with dynamically changing characteristics like global climate change. To increase its ability to process and use this data in a timely manner, NASA’s Marshall Space Flight Center announced a joint development program with IBM Research to process the NASA data using IBM’s foundation AI technology.

To put this task into perspective, the GPT-3 data set, which led to the development of ChatGPT AI platform that recently passed a Wharton MBA exam, represents about 45TB (terabytes) of data. By comparison, NASA estimates that its data set could be upwards of 250PB (petabytes). With 1PB equal to 1,000TB, the NASA data set is over 5,000 times larger than the GPT-3 data set, making this a monumental task, but the benefits could be ground-breaking.

Previously, IBM estimated that 90% of data collected is never used, and in their press invitation, IBM and NASA noted that “Currently, half of all scientific findings come from archived data, which makes it challenging for researchers to study ever-evolving threats such as climate change.” Efficiently mining the enormous amount of archival data needs the power of AI. IBM Research’s massive cloud resources, the collective experiences of the company’s AI experts, and its AI foundation model technology will help NASA filter and analyze earth-science data in days or months rather than years or even decades.

Ultra-thin layers of rust generate electricity from flowing water

Posted by in categories: chemistry, solar power, sustainability

There are many ways to generate electricity—batteries, solar panels, wind turbines, and hydroelectric dams, to name a few examples… and now, there’s rust.

New research conducted by scientists at Caltech and Northwestern University shows that thin films of rust—iron oxide—can generate electricity when saltwater flows over them. These films represent an entirely new way of generating electricity and could be used to develop new forms of sustainable power production.

Interactions between metal compounds and saltwater often generate electricity, but this is usually the result of a chemical reaction in which one or more compounds are converted to new compounds. Reactions like these are what is at work inside batteries.

Scientists solved mystery to make next-gen lithium batteries

Posted by in categories: energy, nanotechnology, sustainability, transportation

Nanoscale defects and mechanical stress cause the failure of solid electrolytes.

A group of researchers has claimed to have found the cause of the recurring short-circuiting issues of lithium metal batteries with solid electrolytes. The team, which consists of members from Stanford University and SLAC National Accelerator Laboratory, aims to further the battery technology, which is lightweight, inflammable, energy-dense, and offers quick-charge capabilities. Such a long-lasting solution can help to overcome the barriers when it comes to the adoption of electric vehicles around the world.
