Excessive blood loss is the leading cause of death from combat injuries, making rapid bleeding control one of the biggest challenges in battlefield medicine. Researchers at KAIST, including an Army Major, have developed a next generation spray-on powder that can stop severe bleeding in about one second. The innovation could significantly improve survival for wounded soldiers while also offering broad potential for civilian emergency care.

The research team, led by Professor Steve Park of KAIST’s Department of Materials Science and Engineering and Professor Sangyong Jon of the Department of Biological Sciences, created a powder type hemostatic agent that quickly transforms into a strong hydrogel barrier whe...

Developers are increasingly relying on large language models (LLMs) for everyday computing tasks such as fixing bugs, explaining code and automating text-processing tasks like filtering logs.

However, it’s not as simple as entering or submitting a question and relying on the model to give you the answer. While humans easily understand these tasks and know exactly what they want, it is difficult to translate them into rigid computer code.

The cloud dilemma
As standard programming is often not up to the task, developers often use AI to handle jobs that are difficult to express as traditional rules...

Scale in the universe is hard to understand from a purely human perspective. Many times, the math just doesn’t sit well with our brains, which evolved to capture and process data about the world around us rather than grok the complexities of stellar dynamics and galaxy mergers. But every once in a while, astronomers find something that, if we can wrap our heads around the numbers, gives a sense of just how big the universe is.

That is precisely what a new paper, available on the arXiv preprint server from a group of astronomers led by Z.L...

Unlike accidental cell death, some cells can actively decide to die through a controlled process. This is called programmed cell death and can occur in different forms, including apoptosis and necroptosis. Cells use this process when they are damaged, stressed, becoming cancerous, or infected by harmful microbes. This self-destruction mechanism helps to protect the body, but it is also involved in many diseases, such as infections, inflammatory conditions and cancer.

A major problem in cancer is that some tumors and cancer cells learn how to avoid apoptosis, allowing them to survive when they should die. This resistance can make cancer treatments less effective, especially in advanced or spreading (metastatic) cancers.

A research team led by Prof. Dr...
