“My work shows that we need to look more carefully at how ocean biology can affect the climate,” said Dr. Jonathan Lauderdale.

How will climate change influence the ocean’s circulation in the future? This is what a recent study published in Nature Communications hopes to address as a researcher from Massachusetts Institute of Technology (MIT) investigated how could hinder the ocean’s mechanisms of transferring carbon between the ocean floor and the planet’s atmosphere. This study holds the potential to help researchers, climate scientists, and the public better understand the long-term impacts of climate change and what steps that can be taken to mitigate them.

For the study, Dr. Jonathan Lauderdale, who is a Research Scientist in the Program in Atmospheres, Oceans, and Climate (PAOC) at MIT used models to challenge previous studies pertaining to the transfer of nutrients, specifically carbon, between the ocean floor and the Earth’s atmosphere, with an emphasis on a specific class of molecules called “ligands”. These previous studies dating back 40 years have hypothesized that weaker ocean circulation results in reduced levels of carbon dioxide being transferred to the atmosphere.

A new way to store carbon captured from the atmosphere, developed by researchers at The University of Texas at Austin, works much faster than current methods without the harmful chemical accelerants they require.

In new research published in ACS Sustainable Chemistry & Engineering, the team developed a technique for ultrafast formation of carbon dioxide hydrates. These unique ice-like materials can bury carbon dioxide in the ocean, preventing it from being released into the atmosphere.

“We’re staring at a huge challenge—finding a way to safely remove gigatons of carbon from our atmosphere—and hydrates offer a universal solution for carbon storage. For them to be a major piece of the carbon storage pie, we need the technology to grow them rapidly and at scale,” said Vaibhav Bahadur, a professor in the Walker Department of Mechanical Engineering who led the research. “We’ve shown that we can quickly grow hydrates without using any chemicals that offset the environmental benefits of carbon capture.”

As artificial intelligence (AI) becomes increasingly ubiquitous in business and governance, its substantial environmental impact — from significant increases in energy and water usage to heightened carbon emissions — cannot be ignored. By 2030, AI’s power demand is expected to rise by 160%. However, adopting more sustainable practices, such as utilizing foundation models, optimizing data processing locations, investing in energy-efficient processors, and leveraging open-source collaborations, can help mitigate these effects. These strategies not only reduce AI’s environmental footprint but also enhance operational efficiency and cost-effectiveness, balancing innovation with sustainability.

Practical steps for reducing AI’s surging demand for water and energy.

Researchers have devised a passive thermal regulation mechanism using common materials that selectively manage radiant heat, providing a sustainable way to significantly improve building energy efficiency and comfort.

Engineers at Princeton and UCLA have developed a passive mechanism to cool buildings in the summer and warm them in the winter.

In an article recently published in the journal Cell Reports Physical Science, they report that by restricting radiant heat flows between buildings and their environment to specific wavelengths, coatings engineered from common materials can achieve energy savings and thermal comfort that goes beyond what traditional building envelopes can achieve.

UChicago Pritzker Molecular Engineering Prof. Y. Shirley Meng’s Laboratory for Energy Storage and Conversion has created the world’s first anode-free sodium solid-state battery.

With this research, the LESC – a collaboration between the UChicago Pritzker School of Molecular Engineering and the University of California San Diego’s Aiiso Yufeng Li Family Department of Chemical and Nano Engineering – has brought the reality of inexpensive, fast-charging, high-capacity batteries for electric vehicles and grid storage closer than ever.

“Although there have been previous sodium, solid-state, and anode-free batteries, no one has been able to successfully combine these three ideas until now,” said UC San Diego PhD candidate Grayson Deysher, first author of a new paper outlining the team’s work.

Researchers have designed a copper nanocluster-based catalyst that converts carbon dioxide into useful methane.

Tesla’s autopilot technology and the increasing affordability of electric vehicles are set to revolutionize the transportation industry, making transportation as a service cheaper and safer, and leading to a significant drop in oil demand and potential geopolitical implications Questions to inspire discussion How safe.

Tesla is preparing to start construction on its upcoming high-volume Semi factory in Nevada, as suggested by huge steel deliveries recently arriving to the site.

In a post on Sunday, X user HinrichsZane shared drone footage from the site of the upcoming Semi factory, which is being built as part of an expansion to Tesla’s existing Gigafactory in Sparks, Nevada. In the footage, you can see a massive amount of steel that was recently delivered to the site, suggesting that the company is nearing the start of construction on the long-awaited Semi factory.

You can see Hinrich’s full video below.
