Researchers discover smarter way to recycle polyurethane
Researchers at Aarhus University have found a better method to recycle polyurethane foam from items like mattresses. This is great news for the budding industry that aims to chemically recover the original components of the material—making their pr.....»»
Researchers develop a test bed for separating valuable material on the moon
It's often better to flesh out technologies fully on Earth's surface before they're used in space. That is doubly true if that technology is part of the critical infrastructure keeping astronauts alive on the moon......»»
Apple accused of using privacy to excuse ignoring child abuse material on iCloud
A proposed class action suit claims that Apple is hiding behind claims of privacy in order to avoid stopping the storage of child sexual abuse material on iCloud, and alleged grooming over iMessage.Apple cancelled its major CSAM proposals but introdu.....»»
Musk’s new Grok upgrade allows X users to create largely uncensored AI images
With Grok's new AI image generator, X users put Musk's "freedom of speech" to the test. Enlarge / An AI-generated image of Donald Trump and catgirls created with Grok, which uses the Flux image synthesis model. (credit: BEAST / X.....»»
Chromatin structure found to play a key role in canine social behavior evolution
A study on dogs found that chromatin's spatial structure has a significant role in the evolution of social behavior. Chromatin, the compact form of DNA, not only packages genetic material but also plays a crucial role in gene regulation......»»
Rapid removal of emerging endocrine disruptors in wastewater using high-performance single-atom catalysts
Bisphenols are widely used as the main raw material for plastics such as receipts, water bottles, water containers, and vinyl due to their heat-resistant and mechanochemical properties. Among bisphenols, bisphenol A (BPA), which we often refer to as.....»»
The biggest-ever sample of core material from Earth"s mantle could have valuable clues into the origins of life
If you were to slice through it, you would see the Earth is divided into distinct layers. On top is the relatively thin crust where we live. Beneath that is the 2,900 km thick mantle layer. Then, enclosed within the mantle is the innermost metallic c.....»»
Developing a simple, cost-effective method to identify the targets of a crucial protein-modifying enzyme
Human proteins undergo a variety of chemical modifications following their synthesis. These modifications regulate their structure, function, and stability. Researchers from the Bhogaraju Group at EMBL Grenoble have developed a new method to study a.....»»
