Type 1 diabetes (T1D) impacts nearly two million Americans, and by the time most people learn they have it, most of the body's insulin-producing cells are destroyed. Now, pinpointing a hidden group of immune "attack" cells in the pancreatic lymph nodes that appear earlier in the disease could offer the first real chance to detect—and even stop—T1D, according to new research from the Perelman School of Medicine at the University of Pennsylvania detailed in Science Immunology.
Pancreatic cancer is the deadliest form of cancer worldwide, mainly because the disease is often discovered late. Symptoms associated with these tumors are often non-specific, so patients and doctors do not immediately suspect cancer. Moreover, these tumors are difficult to detect in the early stages on abdominal CT scans. Once the diagnosis is made, curative treatment is usually no longer possible. Only 10% of patients survive beyond five years.
When designing membranes that separate industrial gases, scientists often incorporate structures that attract the gas they want to obtain. This attraction can enhance the membrane's permeability, and help isolate the desired gas more efficiently.
The understanding of complex many-body dynamics in laser-driven polyatomic molecules is crucial for any attempt to steer chemical reactions by means of intense light fields. Ultrashort and intense X-ray pulses from accelerator-based free electron lasers (FELs) now open the door to directly watch the strong reshaping of molecules by laser fields.
We owe a lot to tissue resident memory T cells (TRM). These specialized immune cells are among the body's first responders to disease.
A vast region of our solar system, called the Kuiper belt, stretches from the orbit of Neptune out to 50 or so astronomical units (AU), where an AU is the distance between Earth and the sun. This region consists mostly of icy objects and small rocky bodies, like Pluto. Scientists believe Kuiper belt objects (KPOs) are remnants left over from the formation of the solar system.
Researchers at Karolinska Institutet in Sweden have identified a brain circuit that can drive repetitive and compulsive behaviors in mice, even when natural rewards such as food or social contact are available. The study has been published in the journal Science Advances and may contribute to increased knowledge about obsessive-compulsive disorder and addiction.
At low temperatures, hydrogen atoms move less like particles and more like waves. This characteristic enables quantum tunneling, the passage of an atom through a barrier with a higher potential energy than the energy of the atom. Understanding how hydrogen atoms move through potential barriers has important industrial applications. However, the small size of hydrogen atoms makes direct observation of their motion extremely challenging.

Traditional surgery (carotid endarterectomy) did not show the same benefit. The research is published in the New England Journal of Medicine.
Ancient Mars boasted abundant water, but the cold and dry conditions of today make liquid water on the Red Planet seem far less probable. However, the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) detected strong radar reflections from a 20-kilometer-wide area over the base of Mars's southern polar ice cap, hinting at the possibility of liquid water below the icy surface. Such a finding would have major implications for the planet's possible habitability.

Whether you're a home gardener or an industrial farmer, you might be familiar with mulching films—plastic sheets laid over the soil to protect seedlings and promote crop growth. But like many other plastic materials, these films can release damaging microplastics and don't have any insect-repelling power. So, a team reporting in ACS Agricultural Science & Technology has developed an alternative biodegradable mulching film that also naturally repels pests using citronella oil.

By exploiting the fluid's spontaneous polarization and exceptionally high dielectric constant, they achieved a strong TEF, previously thought unattainable in conventional electrostatics.
The roots of addiction risk may lie in how young brains function long before substance use begins, according to a new study from Weill Cornell Medicine. The investigators found that children with a family history of substance use disorder (SUD) already showed distinctive patterns of brain activity that differ between boys and girls, which may reflect separate predispositions for addiction.

In Alho's management principle, the vessel's electrical equipment is capable of independently supporting the ship's grid without centralized commands. This makes the vessel's power systems significantly more fault-tolerant than before.

The poplar (Populus alba) has a unique survival strategy: when exposed to hot and dry conditions, it curls its leaves to expose the ventral surface, reflecting sunlight, and at night, the moisture condensed on the leaf surface releases latent heat to prevent frost damage. Plants have evolved such intricate mechanisms in response to dynamic environmental fluctuations in diurnal and seasonal temperature cycles, light intensity, and humidity, but there have been few instances of realizing such a sophisticated thermal management system with artificial materials.
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.
The National Institute of Standards and Technology (NIST) has published a report identifying strategies for developing a more efficient, sustainable and resilient U.S. metals processing infrastructure, where metals are used and reused more efficiently throughout the economy.

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.
After years of design, development, and testing, NASA's X-59 quiet supersonic research aircraft took to the skies for the first time Oct. 28, marking a historic moment for the field of aeronautics research and the agency's "Quesst mission."
