Harder than a diamond, stronger than steel, as flexible as rubber and lighter than aluminum. These are just some of the properties attributed to graphene. Although this material has sparked great interest in the scientific community in recent years, there is still no cheap and sustainable enough method for its high-quality manufacturing on an industrial scale.
Well it does kinda look like a stapler.
This wild-looking people mover can transport up to 20, Musk said.
New Stanford-led research unveils a hidden factor that could change our understanding of how oceans mitigate climate change. The study, published Oct. 11 in Science, reveals never-before seen mucus “parachutes” produced by microscopic marine organisms that significantly slow their sinking, putting the brakes on a process crucial for removing carbon dioxide from the atmosphere.
How can afforestation/reforestation (AR) help reduce climate change and help achieve the goal of the Paris Agreement calling for a maximum 1.5 degrees Celsius above pre-industrial levels? This is what a recent study published in Nature Communications hopes to address as a team of researchers from Germany investigated how AR could contribute to meeting this goal. This study holds the potential to help researchers, climate scientists, legislators, and the public better understand the steps that can be taken to mitigate the effects of climate change, for both the short and long term.
In simple terms, afforestation/reforestation (AR) is planting trees in areas that have experienced deforestation (tree removal) or areas where trees never existed. For the study, the researchers used Integrated Assessment Models (IAMs) to simulate how AR could contribute to the Paris Agreement goals by conducting more than 1,200 scenarios. In the end, the researchers found that AR contributions to climate change makes its biggest impact in 2052, along with decreasing average global temperatures by 0.2 degrees Celsius by the end of the century. Finally, AR could also reduce the amount of time before average global temperatures exceed 1.5 degrees Celsius by 13 years.
“These results show that global AR can in fact make an important contribution to mitigating climate change, when applied at the large sale,” said Dr. Yiannis Moustakis, who is a postdoctoral researcher at Ludwig Maximilians Universität München and lead author of the study. “But it is not a panacea and must be viewed in a more comprehensive framework that takes socioeconomic trade-offs equally into account. Planting a forest could create jobs, revenue, and promote ecosystem services, but it could also deprive people’s livelihood, exacerbate poverty, financially or physically displace people, and disturb local food networks.”
Researchers at the University of California, Irvine and other international institutions have for the first time achieved atomic-scale observations of grain rotation in polycrystalline materials. Widely used in electronic devices, aerospace technologies, automotive applications and solar energy systems, these substances have long been studied for their unique properties and structural dynamics.

German automotive parts giant MAHLE has secured its first order from combustion engine manufacturer DEUTZ to develop and supply components for hydrogen engines. This milestone collaboration, described by MAHLE CEO Arnd Franz as a significant advancement in the automotive industry, signals a growing shift towards sustainable energy alternatives beyond electric vehicles.
Hydrogen fuel, which produces no heat-trapping air pollution at the point of use, could be the future of clean energy. But first, some of the technology around still has to be improved, and researchers at the University of Alberta believe they have made an important step in that direction, AL Circle reported.
The breakthrough out of the University of Alberta is a new alloy material — dubbed AlCrTiVNi5 — that consists of metals such as aluminum and nickel. The alloy has great potential for coating surfaces that have to endure extremely high temperatures, such as gas turbines, power stations, airplane engines, and hydrogen combustion engines.
Hydrogen combustion engines are different from fuel cells, which also run on hydrogen. They are being used to develop cars that run on clean energy. While fuel cells rely on a chemical process to convert hydrogen into electricity, hydrogen combustion engines burn hydrogen fuel, creating energy via combustion, just like a traditional gas-powered car (but without all the pollution).
