Pervasive micropollutants in aquatic environments pose significant threats to global water supply safety. Here, authors achieved permeate concentrations below the detection limit (2.5 ng/L) using a CNT-based electrochemical membrane, with the contributions of adsorption and degradation distinguished.
’The world’s best’ graphene ink, which can be used for printed electronics—such as an intelligent t-shirt that measures your pulse—has been developed in collaboration with the Danish Technological Institute in a MADE demonstration project. The newly developed ink has already opened new markets for the company Danish Graphene.
Imagine a super-strong spider web that can bend and stretch without breaking.
This spider web can conduct electricity better than almost anything else. That’s how graphene works.
One thing’s for sure: If the tech works the way its inventor hopes, the world will never be the same.
Researchers are shining a light on cancer cells’ energy centers—literally—to damage these power sources and trigger widespread cancer cell death. In a new study, scientists combined strategies to deliver energy-disrupting gene therapy using nanoparticles manufactured to zero in only on cancer cells. Experiments showed the targeted therapy is effective at shrinking glioblastoma brain tumors and aggressive breast cancer tumors in mice.
The research team overcame a significant challenge to break up structures inside these cellular energy centers, called mitochondria, with a technique that induces light-activated electrical currents inside the cell. They named the technology mLumiOpto.
“We disrupt the membrane, so mitochondria cannot work functionally to produce energy or work as a signaling hub. This causes programmed cell death followed by DNA damage—our investigations showed these two mechanisms are involved and kill the cancer cells,” said co-lead author Lufang Zhou, professor of biomedical engineering and surgery at The Ohio State University. “This is how the technology works by design.”
New research reshapes our understanding of the universal genetic code, revealing surprising insights into early life’s amino acid evolution.
Data is the new oil, as they say, and perhaps that makes Harvard University the new Exxon. The school announced Thursday the launch of a dataset containing nearly one million public domain books that can be used for training AI models. Under the newly formed Institutional Data Initiative, the project has received funding from both Microsoft and OpenAI, and contains books scanned by Google Books that are old enough that their copyright protection has expired.
Wired in a piece on the new project says the dataset includes a wide variety of books with “classics from Shakespeare, Charles Dickens, and Dante included alongside obscure Czech math textbooks and Welsh pocket dictionaries.” As a general rule, copyright protections last for the lifetime of the author plus an additional 70 years.
Foundational language models, like ChatGPT, that behave like a verisimilitude of a real human require an immense amount of high-quality text for their training—generally the more information they ingest, the better the models perform at imitating humans and serving up knowledge. But that thirst for data has caused problems as the likes of OpenAI have hit walls on how much new information they can find—without stealing it, at least.

In a study, Classiq scientists show how EDA-inspired method reduces qubit and two-qubit gate requirements by orders of magnitude.
Researchers at the University of Sydney Nano Institute have made a significant advance in the field of molecular robotics by developing custom-designed and programmable nanostructures using DNA origami.
This innovative approach has potential across a range of applications, from targeted drug delivery systems to responsive materials and energy-efficient optical signal processing. The method uses ‘DNA origami’, so-called as it uses the natural folding power of DNA, the building blocks of human life, to create new and useful biological structures.
As a proof-of-concept, the researchers made more than 50 nanoscale objects, including a ‘nano-dinosaur’, a ‘dancing robot’ and a mini-Australia that is 150 nanometres wide, a thousand times narrower than a human hair.
Husker researchers Seunghee Kim, Karrie Weber and Hyun-Seob Song are studying the Midcontinent Rift — which runs from beneath Lake Superior through parts of Minnesota, Michigan, Wisconsin, Iowa, Nebraska and Kansas — to determine how best to access a potential store of natural hydrogen that could yield vast amounts of clean energy.
