Paper packaging is a sustainable alternative to plastic. However, as it is permeable to air, food packaged in paper loses its flavor over time, and undesirable substances such as solvents can penetrate the packaging. Up to now, extensive tests were necessary for each type of paper to determine to what extent and how quickly this happens.
A team of researchers has confirmed stars ring loud and clear in a "key" that will harmonize well with the science goals and capabilities of NASA's upcoming Nancy Grace Roman Space Telescope.
A patented RNA-based cocktail developed at the Italian Institute of Technology (IIT-Istituto Italiano di Tecnologia) has emerged as a promising active agent against tumors of the central nervous system, such as glioblastoma.
With a five-year survival rate of less than 5%, glioblastoma is one of the most aggressive types of brain cancer. Until now, all available treatments, including immunotherapy—which involves strengthening the immune system to fight cancer—have proved disappointing. CAR-T cells are genetically modified immune cells manufactured in the laboratory and designed to identify and destroy cancer cells.
Why do no two human faces look quite the same? Although we all follow the same biological blueprint, our features—the curve of a lip, the angle of a nose, the breadth of a jaw—diverge in endlessly subtle ways.
Dysfunctional mitochondria, organelles that serve as cellular power generators, appear to cause the symptoms of Gulf War illness (GWI) among tens of thousands of veterans of the Persian Gulf War, UT Southwestern Medical Center scientists confirmed in a new study.

The discovery, published in Nature Communications, marks a significant advance in the field of materials that compute, in which materials themselves process information without traditional electronic circuitry.
How can we monitor the cross-species transmission of avian flu? The answer is FluWarning, a digital system that reports abnormal changes in flu viruses, developed by a research team from the Politecnico di Milano and the University of Milan. The system analyzes the genetic code of flu viruses, looking for subtle but significant changes that could indicate cross-species transmission (for example, from birds to cattle or to humans), a process known as spillover.
In most narratives, the story of evolution is the story of organisms emerging from the ocean and eventually populating the land. But for some species, that evolution also involved a return trip. Dozens of major mammal and reptile groups ultimately made their way back to the beach and into the water. A new Yale study has undertaken the task of explaining when and how this happened—and which species fully re-committed to the life aquatic. The study is published in the journal Current Biology.
Although present in very small amounts, selenium (Se)-based compounds play important roles in protecting the body from oxidative stress, regulating thyroid hormones, strengthening the immune system, and even detoxifying heavy metals. As we begin to understand more about the biological functions of Se, the need to detect and identify Se-containing compounds has become increasingly important.

In addition, the main product is formate, which requires additional treatment such as acidification to obtain formic acid.
Mitochondria generate most of the body's energy. Variations in their genetic material have long been linked to neurological disorders, metabolic syndromes, and cancers. However, most large-scale mitochondrial DNA (mtDNA) studies to date have focused on European populations, leaving a significant gap in genomic data from East Asia.

Large language models (LLMs) like ChatGPT can write an essay or plan a menu almost instantly. But until recently, it was also easy to stump them. The models, which rely on language patterns to respond to users' queries, often failed at math problems and were not good at complex reasoning. Suddenly, however, they've gotten a lot better at these things.
