Microglial STING-type I interferon signaling is known to play a role in neuroinflammation and neurodegeneration. Yang et al. find that STING is also expressed in Purkinje neurons. STING activation dysregulates the autonomous firing and pace-making function of Purkinje neurons independently of interferon signaling, leading to neurodegeneration and cerebellar ataxia.
The modified strain grows faster, uses far fewer resources, and lowers greenhouse gas emissions by up to 60%. It also dramatically outperforms chicken farming in land and water use. The findings highlight a promising path for eco-friendly protein…
…’There is a popular demand for better and more sustainable protein for food,’ says corresponding author Xiao Liu of Jiangnan University in Wuxi, China. ‘We successfully made a fungus not only more nutritious but also more environmentally friendly by tweaking its genes.’
Animal agriculture contributes roughly 14% of global greenhouse gas emissions. It also requires large areas of land and significant amounts of fresh water, which are already under pressure from climate change and human activity. Because of these drawbacks, microbial proteins found in organisms such as yeast and fungi are gaining attention as a more sustainable alternative to traditional meat.
CRISPR has turned a simple fungus into a fast-growing, meat-like protein source with impressively low environmental impact.
Water is all around us, yet its surface layer—home to chemical reactions that shape life on Earth—is surprisingly hard to study. Experiments at SLAC’s X-ray laser are bringing it into focus.
Two-thirds of Earth’s surface is covered in water, most of it in oceans so deep and vast that only one-fifth of their total volume has been explored. Surprisingly, though, the most accessible part of this watery realm—the water’s surface, exposed on wave tops, raindrops and ponds full of skittering water striders—is one of the hardest to get to know.
Just a few layers of atoms thick, the surface plays an outsized role in the chemistry that makes our world what it is—from the formation of clouds and the recycling of water through rainfall to the ocean’s absorption of carbon dioxide from the atmosphere.
President Donald Trump decided to let Nvidia Corp. sell its H200 artificial intelligence chips to China after concluding the move carried a lower security risk because the company’s Chinese archrival, Huawei Technologies Co., already offers AI systems with comparable performance, according to a person familiar with the deliberations.
Administration officials who weighed whether to clear Nvidia’s H200 had considered multiple possible scenarios, factoring in the views of national security hawks in Washington, said the person. Options ranged from exporting zero AI chips to China to allowing exports of everything to flood the Chinese market and overwhelm Huawei. Ultimately the policy backed by Trump called for clearing H200s to China while holding back the latest Nvidia chips for American customers, the person said.
A global research team led by researchers from the University of Kentucky Martin-Gatton College of Agriculture, Food and Environment has found that Antarctica’s only native insect is already ingesting microplastics, even in one of the planet’s most remote regions.
The study, published in the journal Science of the Total Environment, is the first to examine how microplastics affect an Antarctic insect and to document plastic pieces inside wild-caught midges.
Jack Devlin, who led the work back in 2020 as part of his Ph.D. before moving to Scotland to work as a marine ornithologist, said the project started after a documentary on plastic pollution left him stunned.
A joint research team has developed a highly efficient photocatalyst that can convert carbon dioxide into the high-value-added fuel, methane, using sunlight, while explaining its operating principles. The work is published in the journal ACS Catalysis.
Carbon dioxide is a typical greenhouse gas, considered a major cause of climate change, and developing technologies to effectively reduce it is an important challenge worldwide.
The photocatalyst technology that caught the interest of the research team is a type of artificial photosynthesis technology that uses solar energy to convert carbon dioxide into fuel. It has garnered significant attention for its potential to contribute to carbon neutrality and eco-friendly energy production.
Billions of alkaline-loving microbes could offer a new way to protect nuclear waste buried deep underground. This approach overcomes the limitations of current cement barriers, which can crack or break down over time.
One of the best ways to keep nuclear waste out of harm’s way is to bury it in geological disposal facilities. These are purpose-built containers in tunnels and vaults hundreds of meters underground. Cement is used to provide structural support, seal gaps and encapsulate waste containers. While cement is a strong material, groundwater eventually reacts with it, forming microscopic cracks and pores through which radiation could escape.
This problem is made worse because traditional cement is extremely alkaline (pH greater than 12) and corrosive, which can weaken nearby protective layers such as clay barriers, potentially compromising a facility.

A research team from NIMS, Tohoku University and AIST has developed a new technique for controlling the nanostructures and magnetic domain structures of iron-based soft amorphous ribbons, achieving more than a 50% reduction in core loss compared with the initial amorphous material.
The developed material exhibits particularly high performance in the high-frequency range of several tens of kilohertz—required for next-generation, high-frequency transformers and EV drive power supply circuits. This breakthrough is expected to contribute to the advancement of these technologies, development of more energy-efficient electric machines and progress toward carbon neutrality.
The research is published in Nature Communications.
