Bloomberg Philanthropies has identified a funding shortfall in the implementation of many countries’ ocean protection plans, and has attempted to fill it with a quarter-billion dollar donation.
The aim writ small is to translate the paper gains for ocean conservation and management secured with the passage of the UN’s new High Seas Treaty into real gains by helping to cover the cost of management and enforcement for small island nations that lack these resources.
The updated High Seas Treaty has been under negotiation for over 2 decades. Its passage secured major gains for the potential protection of critical ocean habitats.
As the adoption of electric vehicles continues to grow, so does the need for the safe and permanent storage of battery materials and industrial chemical waste. Certain waste streams require disposal in what are known as Category IV landfills, which impose particularly stringent requirements on storage containers. These must simultaneously ensure environmental protection, safe handling and long-term structural integrity.
Glass is a highly promising material for this application: It is exceptionally chemically inert—meaning it reacts with virtually no other substances—making thick-walled glass containers especially well-suited for the permanent containment of hazardous materials. Glass containers are also of particular interest in the context of potential new recycling methods in the future. The stored residual materials do not react with the containers and can be readily recovered from them.
Until now, these glass containers have been manufactured primarily using thermal gas processes. However, these are limited by uncontrolled heat input, high residual stresses and restricted automation potential. Laser welding, on the other hand, enables high processing speeds and shows excellent potential for automation.
In the future, iron might be used as a chemical energy storage material, making large quantities of renewable energy available in the long term. Iron powder is combusted in a cyclic process that is carbon neutral and then reconverted to its original state using energy input. Scientists at Karlsruhe Institute of Technology (KIT) were the first to conduct an extensive study to evaluate the potential of this technology for power generation. Their results show that iron, while not superseding hydrogen, may usefully complement it in a climate-neutral energy system. The findings have been published in Chem Circularity.
Be it for wind energy from coastal regions or for solar power from desert areas, iron could serve as a transportable energy carrier in the future to make these renewable energy sources usable worldwide. “This works in a cycle that emits no carbon dioxide or environmentally harmful substances,” said Julia Schuler from KIT’s Institute for Industrial Production (IIP). For power generation, iron powder is combusted, producing iron oxide, i.e. rust. Using hydrogen from renewable sources, it is reduced to iron again in a process that removes the oxygen it contains. The iron powder can then be reused.
“When burned, iron powder behaves very much like coal. We wanted to find out whether it was possible to repurpose existing coal power plants to iron-firing,” said Schuler. She believes that modifications are primarily necessary in the heat generator; other components, such as the steam cycle, turbines, generator and power grid connection, could continue to be used.
🫣🤫🤔 Let’s face it: we’re still a Type 0 civilization on the Kardashev Scale… though, to be honest, we’re much closer to the Kardashian Scale 😁 endless entertainment, constant distractions, and celebrity obsession. 🙈🙉🙊 A true Type I civilization would be focused on mastering energy, advancing science, and solving humanity’s biggest challenges. We’ve still got a long way to go! While most people’s main concerns revolve around material comfort, entertainment, and instant gratification, who truly cares about the fate of the most vulnerable? About social exclusion? Inequality? The pollution and destruction of our environment? Who cares about the massive extinction of million of species now underway? Who cares about sustainable development and peace for everyone? A true Type I civilization would be collectively focused on optimizing how it functions and shaping a better future for everyone. We’re still very, very far from that.

Mark Ciotola, CEO and Co-Founder of Sustain Space.
Everyone talks about getting humans to Mars. But almost nobody talks about the harder question — how do you keep them alive once they get there? My guest today says the answer isn’t bigger rockets — it’s plants.
Mark Ciotola is CEO and Co-Founder of Sustain Space (https://www.sustainspace.com/), a company focused on developing regenerative life-support technologies for future space missions while translating those innovations to improve agriculture and sustainability on Earth. Through Sustain Space’s Orbital Genomics initiative, he is helping advance research into growing plants in space environments — an essential capability for long-duration missions to the Moon, Mars, and beyond.
Mark’s career spans entrepreneurship, academia, industry, and government, including work with NASA, Genentech, Applied Biosystems, Intuit, Carnegie Mellon University, Monash University, San Francisco State University, and Singularity University, where he served as Entrepreneur-in-Residence and faculty member in Space and Physical Sciences.
A physicist, entrepreneur, educator, and sustainability advocate, Mark is particularly interested in regenerative ecosystems, closed-loop life-support systems, space agriculture, and the broader question of how humanity can build a sustainable future both on Earth and beyond it.
The research group of Professor Kotohiro Nomura, Tokyo Metropolitan University, in cooperation with the research groups of Senior Researcher Hiroshi Hirano and Director Seiji Higashi of the Osaka Research Institute of Industrial Science and Technology, and Associate Professor Hiroki Takeshita of The University of Shiga Prefecture, has developed biobased poly(ester amide)s from inedible biorenewables that can be easily chemically recycled and exhibit better mechanical (tensile) properties in film than commodity plastics.
The work has been published in JACS Au.
The development of biobased polymers that are readily chemically recyclable and derived from nonedible renewable resources has been recognized as a promising sustainable material in the circular economy. However, there have been few examples of materials with mechanical properties (e.g. tensile strength and elongation at break) that exceed those of conventional polymers such as polyethylene and polypropylene.
A new manufacturing technique developed by Concordia researchers could make small wind turbines lighter, less expensive and easier to produce. Using a process known as 4D printing of composites, Ph.D. candidate Emad Fakhimi and Suong Van Hoa, a professor at the Concordia Center for Composites, created curved blades for vertical-axis wind turbines from flat carbon-fiber composite panels. The study is published in the journal Polymer Composites.
Vertical-axis wind turbines are increasingly used on buildings and in urban settings, but their curved blades are typically made using specialized forming processes that require complex molds. These molds add cost, manufacturing time and weight to the final product.
To address this problem, the researchers developed a new, first-of-its-kind “inverse” design procedure. Rather than starting with a particular layup—the arrangement and orientation of carbon-fiber layers—and observing the resulting shape, they began with the desired blade geometry and worked backward to determine how the layers should be arranged and oriented to produce it.
Storing solar and wind energy to meet the increasing power needs of the electrical grid calls for devices that can deliver power quickly, recharge quickly and last for decades at low cost. A new study led by UCLA has uncovered a technology that could meet all these criteria: a zinc-ion hybrid battery with a 3D-printed electrode that stores more than seven times the charge of similar hybrids.
“The future of energy storage won’t be defined by a single technology,” said co-corresponding author Maher El-Kady, an assistant researcher in UCLA College’s chemistry and biochemistry department. “At some point, we will need to look for something to complement the current options for grid-scale energy storage. What we’ve done in this study essentially gives us zinc-ion hybrid devices that can store nearly one order of magnitude higher capacity.”
A newly developed framework for understanding the photoproperties of both natural organic matter and eumelanin, a natural pigment responsible for dark colors in organisms, may inspire advanced sustainable technologies, scientists say.
Although they are some of the most widespread substances on Earth, not much is known about eumelanin or natural organic matter (NOM)—a dark-colored substance formed by the decomposition of biological material. In humans, eumelanin is a vital pigment in skin and other tissues that protects cells from damage caused by ultraviolet radiation. In nature, NOM gives rivers and soils their color and affects light-driven reactions like photosynthesis.
Although these compounds have been studied individually for decades, researchers in a new study, by scrutinizing them alongside each other, have shown that eumelanin and NOM have common properties beyond their dark colors.
