A collaborative research team has introduced a nitrogen-centric framework that explains the light-absorbing effects of atmospheric organic aerosols. Published in Science, this study reveals that nitrogen-containing compounds play a dominant role in the absorption of sunlight by atmospheric organic aerosols worldwide. This discovery signifies a major step towards improving climate models and developing more targeted strategies to mitigate the climate impact of airborne particles.

Atmospheric organic aerosols influence climate by absorbing and scattering sunlight, particularly within the near-ultraviolet to visible range. Due to their complex composition and continuous chemical transformation in the atmosphere, accurately assessing their climate effects has remained a challenge.

The study was jointly led by Prof. Fu Tzung-May, Professor of the School of Environmental Science and Engineering at Southern University of Science and Technology (SUSTech) and National Center for Applied Mathematics Shenzhen (NCAMS), and Prof. Yu Jianzhen, Chair Professor of the Department of Chemistry and the Division of Environment and Sustainability at Hong Kong University of Science and Technology (HKUST).

What impacts have climate change mitigation strategies had on the ozone layer? This is what a recent study published in Nature hopes to address as a team of researchers led by the Massachusetts Institute of Technology (MIT) investigated the rate of Antarctic ozone recovery due to a reduction in human-caused ozone-depleting substances (ODSs). This study has the potential to help researchers, climate scientists, legislators, and the public better understand the benefits of climate change mitigation strategies on healing the environment for both the short and long term.

For the study, the researchers used a combination of satellite imagery data and a series of computer models to ascertain the extent of the Antarctic ozone recovery based on seasons and altitude between 2005 and now. The team conducted various models to identify a pattern in Antarctic ozone recovery, which they call a “fingerprint”. After comparing this to the satellite data, the team ascertained that the Antarctic ozone has been healing due to decreased levels of ODSs.

“After 15 years of observational records, we see this signal to noise with 95 percent confidence, suggesting there’s only a very small chance that the observed pattern similarity can be explained by variability noise,” said Peidong Wang, who is a PhD student in MIT’s Department of Earth, Atmospheric and Planetary Sciences and lead author of the study. “This gives us confidence in the fingerprint. It also gives us confidence that we can solve environmental problems. What we can learn from ozone studies is how different countries can swiftly follow these treaties to decrease emissions.”

Using body parts from simple animals in robotics is not as controversial. But it’s still important to consider the impact on these living creatures. It may seem that bugs and jellyfish and mollusks aren’t capable of caring about how we use their bodies. But what if we’re wrong about that? Some researchers are finding that such creatures might have more awareness and feelings than expected.

Living robots also interact with the environment. What if a jellyfish outfitted with electronics got eaten? Xu is hoping to develop biodegradable electronics that wouldn’t harm other animals or pollute the ocean.

Biohybrid robots blur the line between machine and living thing. The jellyfish cyborgs are obviously still alive. But most biohybrids don’t really fit into one category or the other. Shin says of her heart-cell-covered bot: “it’s not a creature.” But it’s not a typical robot, either.

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.

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.
