Integrated solar reactor paves way to make 'clean' chemicals, plastics and food using solar energy‎

A new study led by Dr. Lin Su of Queen Mary University of London, published today in the Journal of the American Chemical Society, describes a new integrated solar reactor in which engineered Escherichia coli (E. coli) are grown directly inside the same liquid that converts CO₂ into a usable energy source using sunlight.

Mainstream anime moments can create big business opportunities‎

Anime has gone mainstream in the United States, drawing millions of fans who spend big money on conventions, streaming, gaming, and merchandise. But anime is no longer reserved just for cosplayers. Now, businesses and sports franchises are increasingly tapping into anime culture to grow audiences, strengthen fan loyalty, and create new revenue opportunities.

Laser processes to enable robust, miniaturized beam sources for quantum technology‎

In the HiPEQ project, a consortium of industry and research partners has developed new laser-based approaches to enable miniaturized, robust beam sources for quantum technology. Among others, the consortium also used lasers to grow novel optical insulator crystals. The project achieved significant progress from November 2021 to July 2025. Fraunhofer ILT in Aachen played a key role by co-developing the laser processes needed.

Protected areas that help wildlife often do little for the soil fungi on which plants depend‎

Governments around the world conserve plants and animals in part by setting aside land. Whether as wilderness reserves or as resource management zones that allow industrial activities such as logging, 17.4% of the planet's land offers some measure of protection. These protected areas overlap with one-fifth, on average, of the range of Earth's terrestrial mammals. But beneath these parched deserts, dark forests, and rolling grasslands is an invisible world that keeps these aboveground places healthy. And we're not protecting that world much at all.

Beyond 0 and 1: Ferrotoroidic material can store four magnetic states‎

Today's computers store information using only two values: 0 and 1. But as electronic devices become smaller and reach their limits, scientists are searching for new ways to pack more information into the same space. One idea is to use magnetism. In some materials, atoms behave like tiny magnets that can arrange themselves in different patterns. If each pattern represents a different value, one memory element could store more than just two possibilities.

Seaweed study unlocks surprising solution for cattle nutrition and sustainable agriculture‎

Cows eat grass...everyone knows that. But climate change is forcing producers and scientists to rethink some of our long-held assumptions about livestock nutrition. Crop costs are climbing. Traditional pastures are under pressure. And researchers are casting a wider net for unconventional feed sources that might help the industry adapt.

Mining 231,705 Roblox reviews reveals which user problems need fastest fixes‎

Service quality improvement requires a holistic approach to analyzing customer reviews and identifying relevant, actionable issues. Researchers from South Korea have addressed this by developing a model that integrates service-specific aspects and customer actions, which are typically analyzed separately in text mining studies. They also validated the model using online customer reviews of a metaverse platform, demonstrating its potential to help service managers identify high-priority issues and allocate resources strategically.

Migrating charges unlock hard-to-reach C-H bond edits in organic molecules‎

A team at the University of Vienna, led by chemist Nuno Maulide, has developed a new method for controlling chemical reactions in a more targeted and efficient manner. At the heart of this is the concept of "cation sampling": specially selected groups (ketones), in a sense, function as molecular signposts for randomly migrating positive charges, enabling reactions to take place at sites on a molecule that were previously difficult to access. The method allows carbon-hydrogen bonds (C–H bonds) to be specifically modified. The study was published in the Journal of the American Chemical Society.

Persistent violence gaps hit Black and multiracial women hardest in California, analysis shows‎

Rates of violence against women have remained largely unchanged in California for nearly two decades, with Black and multiracial women facing the highest risks, a sweeping new analysis by UC Berkeley public health researchers has found.
