Glioblastoma cancer cells use mitochondria from the central nervous system to grow and form more aggressive tumors, according to new Cleveland Clinic-led findings published in Nature Cancer. The research showed that it is common for healthy astrocytes – a type of glial cell with important functions in the central nervous system – to transfer the energy-producing organelles to glioblastoma cancer cells. When this process happens, it makes the cancer more deadly and the tumors more likely to grow. Researchers found that acquiring mitochondria ...

UCLA researchers have developed an “all-in-one,” next-generation statistical simulator capable of assimilating a wide range of information to generate realistic synthetic data and provide a benchmarking tool for medical and biological researchers who use advanced technologies to study diseases and potential therapies. Specifically, the new computer-modeling – or “in silico” – system can help researchers evaluate and validate computational methods. Single-cell RNA sequencing, called single-cell transcriptomics, is the foundation for analyzing genetic makeup (genome-wide gene ...

CAMBRIDGE, MA -- Genomic studies of cancer patients have revealed thousands of mutations linked to tumor development. However, for the vast majority of those mutations, researchers are unsure of how they contribute to cancer because there’s no easy way to study them in animal models. In an advance that could help scientists make a dent in that long list of unexplored mutations, MIT researchers have developed a way to easily engineer specific cancer-linked mutations into mouse models. Using this technique, which ...

Obstructive sleep apnea associated with increased risks for long COVID Study suggests adults with both the sleep disorder and COVID may benefit from clinical monitoring   Among people who have had COVID-19, adults with obstructive sleep apnea were more likely to experience long-term symptoms suggestive of long COVID than those without the sleep disorder, according to a large study supported by the National Institutes of Health (NIH). In fact, multiple analyses of electronic health records (EHR) identified adults with sleep apnea may have up to a 75% higher risk ...

The senses represent our gates to receive information from the environment, but not all of them are always available for everyone, as in the case of blind or deaf people. Researchers know today quite well that the brain has the critical ability to adapt to different sensory experiences and, in some ways, to “compensate” for the lack of one sense or the other. In a recent study, a group of researchers from the IMT School for Advanced Studies Lucca (Italy), in collaboration with a group from the University of Ulm (Germany), ...

New lens analysis approach could improve treatments for nearsightedness Instrumentation recreates properties of the myopic eye to test lenses that prevent visual decline WASHINGTON — Researchers have developed new instruments for rigorously quantifying and comparing the light focusing properties of specialized eyeglass lenses that are used to slow the progression of myopia, or nearsightedness. The information gained with this new approach could help inform future lens designs that are even more effective at preventing visual decline. Nearsightedness is on the rise around the globe, especially among children. If current trends continue, ...

In a recent study, researchers determined that derivatives of natural emulsifiers such as phospholipids found in high-fat, high-cholesterol diets can promote atherosclerosis via gut bacteria interactions with the immune system. This study could pave the way for targeted interventions for individuals who are at risk for developing heart disease. Obesity and a high-cholesterol, high-fat diet are both well-established risk factors for atherosclerosis. In fact, obese individuals are two and a half times more likely to develop heart disease. ...

The common ragweed plant (Ambrosia artemisiifolia) has spread rapidly in Europe and has intensified the pollen season for many allergy sufferers. Now the plant has arrived in Norway. Common ragweed can extend Norway's pollen season into November, but fortunately the species is struggling in this country. “Common ragweed can be found in Norway, but for now it has no stable populations,” says Vanessa Carina Bieker, a postdoc at the Norwegian University of Science and Technology's (NTNU) ...

Proteins tend to fold wrongly and become defective when exposed to stressors such as heat, oxidation, and pH changes. Accumulation of abnormal proteins contributes to neurodegenerative diseases like Alzheimer’s. So, how does the human body deal with such misfolded or defective proteins? It regulates protein networks via a process called ‘proteostasis,’ which prevents protein aggregation and any damage that may result from misfolded protein accumulation inside (intracellular) or outside (extracellular) cells. A set of unique proteins—molecular chaperones—play an essential role in proteostasis: they target and interact with misfolded proteins, maintain their solubility, ...

Much of what is now considered modern medicine originated as folk remedies or traditional, Indigenous practices. These customs are still alive today, and they could help address a variety of conditions. Now reporting in ACS Omega, a team of researchers have identified compounds in the leaves of a particular medicinal Labrador tea plant used throughout the First Nations of Nunavik, Canada, and demonstrated that one of them has activity against the parasite responsible for malaria. “Labrador tea” refers to multiple, closely related plants — all members of the genus Rhododendron. ...

Using ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA), astronomers have created a vast infrared atlas of five nearby stellar nurseries by piecing together more than one million images. These large mosaics reveal young stars in the making, embedded in thick clouds of dust. Thanks to these observations, astronomers have a unique tool with which to decipher the complex puzzle of stellar birth. “In these images we can detect even the faintest sources of light, like stars far less massive than the Sun, revealing objects that no one has ever seen before,” says Stefan Meingast, an astronomer at the University of Vienna in Austria and lead author ...

Osaka, Japan – Ischemic stroke, caused by a blockage of blood flow to the brain, is a common cause of death and disability. Treatments are urgently needed to improve patient outcomes, because recovery currently depends largely on the timely injection of a blood clot-dissolving drug. Priorities for therapy include limiting inflammation at the ischemic site and rebuilding neuronal connections damaged by the stroke. However, a molecule that can achieve these therapeutic effects has remained elusive. In a study to be published in Stroke, researchers from Osaka University provide new hope for patients. They have identified ...
