Affordable hydrogen production with a low-cost palladium-based nanosheet
Hydrogen energy promises a clean and sustainable future, but its production often depends on expensive platinum-based catalysts, making it costly. The industry needs more affordable alternatives to platinum to make hydrogen energy more viable.
Researchers from the Tokyo University of Science (TUS) have developed a new catalyst called bis(diimino)palladium coordination nanosheets (PdDI). These low-cost palladium-based nanosheets match platinum’s performance in producing hydrogen.
Nuclear fusion: WEST beats the world record for plasma duration!
France just achieved a nuclear fusion breakthrough, making limitless energy virtually inevitable.
In a major achievement, France’s WEST Tokamak reactor has maintained a plasma reaction for over 22 minutes, setting a new world record in the quest for sustainable fusion energy.
énergie atomique et aux énergies alternatives (CEA), the experiment surpassed China’s previous record of 1,066 seconds, reaching 1,337 seconds of sustained plasma. + This milestone is a major step toward commercial fusion power, which promises unlimited, clean energy by harnessing the same process that powers the Sun. The challenge lies in achieving a self-sustaining reaction while maintaining extreme temperatures of up to 150 million°C (270 million°F) without damaging reactor components.
While WEST itself won’t become a commercial reactor, the data gathered will be instrumental in developing ITER, the world’s largest fusion project, currently under construction in southern France.
CEA scientists plan to extend reaction times further, increasing power levels and plasma stability. If successful, these advancements could bring humanity closer to realizing the long-held dream of clean, virtually limitless energy, potentially transforming global power generation in the future.

Solar-powered device captures carbon dioxide from air to make sustainable fuel
Researchers have developed a reactor that pulls carbon dioxide directly from the air and converts it into sustainable fuel, using sunlight as the power source.
The researchers, from the University of Cambridge, say their solar-powered reactor could be used to make fuel to power cars and planes, or the many chemical and pharmaceutical products we rely on. It could also be used to generate fuel in remote or off-grid locations.
Unlike most carbon capture technologies, the reactor developed by the Cambridge researchers does not require fossil-fuel-based power, or the transport and storage of carbon dioxide, but instead converts atmospheric CO2 into something useful using sunlight. The results are reported in the journal Nature Energy.

Findings on butanol toxicity may enable cheaper biofuel production
One limitation of producing biofuel is that the alcohol created by fermentation is toxic to the microbes that produce it. Now scientists are closer to overcoming this obstacle.
Researchers from the University of Cincinnati and the U.S. Department of Energy’s Oak Ridge National Laboratory have achieved a breakthrough in understanding the vulnerability of microbes to the alcohols they produce during fermentation of plant biomass.
With the national lab’s neutron scattering and simulation equipment, the team analyzed fermentation of the biofuel butanol, an energy-packed alcohol that also can be used as a solvent or chemical feedstock.
How 3D Printing Is Powering a Cleaner Environment in the Future
3D printing is revolutionizing microbial electrochemical systems (MES) by enabling precise reactor design, custom electrode fabrication, and enhanced bioprinting applications. These innovations optimize pollutant degradation and energy production, with significant implications for sustainability and environmental management.
Microbial electrochemical systems (MES) are emerging as a promising technology for addressing environmental challenges by leveraging microorganisms to transfer electrons. These systems can simultaneously degrade pollutants and generate electricity, making them valuable for sustainable wastewater treatment and energy production.
However, conventional methods for constructing MES components often lack design flexibility, limiting performance optimization. To overcome these limitations and enhance MES efficiency, innovative fabrication techniques are needed—ones that allow precise control over reactor structures and functions.
Here’s how to book a driverless Uber ride in Austin
AUSTIN (KXAN) — Beep beep — Uber rideshare users can now book a driverless ride around Austin, as the ridehailing company officially launches its partnership with Waymo.
Waymo and Uber announced in September the planned collaboration between the two companies, with rollouts poised in both Austin and Atlanta in 2025. Beginning Tuesday, Uber users can match with one of Waymo’s Jaguar I-PACE vehicles while booking an UberX, Uber Green, Uber Comfort or Uber Comfort Electric vehicle.
“Starting today, Austin riders can be matched with a Waymo autonomous vehicle on the Uber app, making their next trip even more special,” Uber CEO Dara Khosrowshahi said in the announcement. “With Waymo’s technology and Uber’s proven platform, we’re excited to introduce our customers to a future of transportation that is increasingly electric and autonomous.”
New Methane Flare Tech: Efficiency Plus Combustion Stability
“A good ratio of oxygen to methane is key to combustion,” said Justin Long.
Can methane flare burners be advanced to produce less methane? This is what a recent study published in Industrial & Engineering Chemistry Research hopes to address as a team of researchers from the University of Michigan (U-M) and the Southwest Research Institute (SwRI) developed a methane flare burner with increased combustion stability and efficiency compared to traditional methane flare burners. This study has the potential to develop more environmentally friendly burners to combat human-caused climate change, specifically since methane is a far larger contributor to climate change than carbon dioxide.
For the study, the researchers used a combination of machine learning and novel manufacturing methods to test several designs of a methane flare burner that incorporates crosswinds to simulate real-world environments. The burner design includes splitting the methane flow in three directions while enabling oxygen flow from crosswinds to mix with the methane, enabling a much cleaner combustion. In the end, the researchers found that their design achieves 98 percent combustion efficiency, meaning it produces 98 percent less methane than traditional burners.
“A good ratio of oxygen to methane is key to combustion,” said Justin Long, who is a Senior Research Engineer at SwRI. “The surrounding air needs to be captured and incorporated to mix with the methane, but too much can dilute it. U-M researchers conducted a lot of computational fluid dynamics work to find a design with an optimal air-methane balance, even when subjected to high-crosswind conditions.”
Predicting the Future: When Will the Next Ice Age Begin?
“The pattern we found is so reproducible that we were able to make an accurate prediction of when each interglacial period of the past million years or so would occur and how long each would last,” said Dr. Stephen Barker.
Earth has experienced several climate cycles throughout its long history, including several ice ages that caused the planet to freeze over. The last ice age occurred approximately 11,700 years ago, but when could the next one occur? This is what a recent study published in Science hopes to address as an international team of researchers investigated specific characteristics that could help predict Earth’s next ice age. This study has the potential to help researchers, climate scientists, and the public better understand Earth’s climate history and how climate change could alter this history.
For the study, the researchers analyzed Earth’s climate history over the last one million years and compared this data to changes in Earth’s axial tilt, the axial tilt’s wobble (also called precession), and changes in Earth’s orbit around the Sun. The goal of the study was to connect these planetary parameters to past ice ages, also called glacial periods, while also attempting to predict future ice ages without human-caused climate change.
In the end, the researchers not only discovered when every ice age occurred over the past 900,000 years, but they predict the Earth will have approximately 10,000 years until the next ice age, noting we are currently in an interglacial period known as the Holocene.
