The imaging techniques currently used in biological research cannot penetrate into deeper tissue layers. In cancer treatment, this means that remnants of tumors or individual cancer cells at tumor margins and in lymph nodes are not visible. Doctors performing surgery are therefore repeatedly faced with the difficult question of whether all of the affected tissue has actually been removed. For the patient's quality of life, however, the complete removal of the tumor is just as essential as the preservation of healthy tissue ...

To the known risk factors for cardiovascular disease—high blood pressure, high cholesterol, diabetes, overweight and obesity, smoking, and physical inactivity—a new one has to be added: clonal hematopoiesis. This condition is triggered by acquired mutations in blood stem cells and was already known to be associated with an elevated cardiovascular risk. However, until now it was uncertain if clonal hematopoiesis was a cause or consequence of cardiovascular disease. Now, a new study published in Nature Medicine and carried out by researchers at the Centro Nacional de Investigaciones Cardiovasculares (CNIC) resolves this critical debate ...

Climate change is affecting ecosystems in many different ways. One of its consequences are increasingly longer and more intense periods of heat, which affect essential natural processes –  such as pollination. A team of researchers from Julius-Maximilians-Universität Würzburg (JMU) has now investigated in more detail how heat affects one particular player in these processes: The bumblebee. "Bumblebees are important pollinators in natural and agricultural systems. They therefore ...

HER2 is a critical protein that plays a pivotal role in breast cancer cell growth and aggressiveness. Its expression level is a key indicator for treatment decisions, including the use of HER2-targeted therapies. Currently, HER2 status assessment relies heavily on immunohistochemical (IHC) staining of tissue slides followed by manual inspection by pathologists. This process, though widely adopted, suffers from several limitations, including poor reproducibility among pathologists and extended turnaround times. These challenges are further exacerbated in resource-constrained ...

BUFFALO, NY- August 30, 2024 – A new editorial was published in Volume 11 of Oncoscience on July 19, 2024, entitled, “Functional information offers individualized adaptive cancer therapies.” As introduced in this editorial, the Oxford Computer Science Dictionary offers both general and technical definitions of information. Generally, information is anything that can cause a change in a human mind's opinion about the current state of the real world. Technically, information is anything that reduces the uncertainty of a system's state. Claude Shannon provided an objective measure of information, known as entropy (H), by mathematically defining ...

While some microbes can make people sick or spoil food, others are critical for survival. These tiny organisms can also be engineered to make specific molecules. Researchers reporting in ACS Sustainable Chemistry & Engineering have rewired one such microbe to help tackle greenhouse gases in the atmosphere: It takes in carbon dioxide (CO2) gas and produces mevalonate, a useful building block for pharmaceuticals. The increasing concentration of greenhouse gases in the atmosphere has led to widespread global warming. To begin to address the problem, greenhouse gas emissions, including CO2, need to be significantly ...

Understanding how cells process nutrients and produce energy - collectively known as metabolism - is essential in biology. However, analyzing the vast amounts of data on cellular processes to determine metabolic states is a complex task. Modern biology generates large datasets on various cellular activities. These "omics" datasets provide insights into different cellular functions, such as gene activity and protein levels. However, integrating and making sense of these datasets to understand cell metabolism is challenging. Kinetic models offer a way to decode this complexity by providing mathematical representations of cellular metabolism. ...

CAMBRDIGE, MA – In order to train more powerful large language models, researchers use vast dataset collections that blend diverse data from thousands of web sources. But as these datasets are combined and recombined into multiple collections, important information about their origins and restrictions on how they can be used are often lost or confounded in the shuffle. Not only does this raise legal and ethical concerns, it can also damage a model’s performance. For instance, if a dataset is miscategorized, someone training a machine-learning model for a certain task may end up unwittingly using data that are not designed for that task. In addition, data from unknown sources ...
