Imagine being able to count the different types of blood cells being formed inside the tiny bones of a mouse and pinpointing the strings and clusters of cells within the bone marrow that are responsible for producing specific types of blood cells.
The results of a study published today in Nature Medicine show exciting immune responses in patients with operable esophageal or gastroesophageal cancers given neoadjuvant immunotherapy. The study results also show the potential for monitoring circulating tumor DNA as a predictor for future intervention.
وفقًا لدراسة أجرتها مايو كلينك ونُشرت في مجلة Nature Neuroscience، فإن الخلايا التي تعمل كخط الدفاع الأول للجهاز العصبي المركزي ضد الأخطار تلعب دورًا أيضًا في مساعدة الدماغ على الاستفاقة من التخدير. ويمكن أن يساعد هذا الاكتشاف في تمهيد الطريق للتوصل لأساليب مبتكرة تعالج مضاعفات ما بعد التخدير.
De acordo com um estudo da Mayo Clinic publicado pela Nature Neuroscience, as células que atuam na primeira linha de defesa do sistema nervoso central contra lesões também desempenham um papel em ajudar o cérebro a despertar da anestesia. Esta descoberta pode ajudar a pavimentar o caminho para métodos inovadores que abordam as complicações pós-anestésicas.

Monitoring levels of DNA shed by tumors and circulating in the bloodstream could help doctors accurately assess how gastroesophageal cancers are responding to treatment, and potentially predict future prognosis, suggests a new study led by researchers at the Johns Hopkins Kimmel Cancer Center and its Bloomberg~Kimmel Institute for Cancer Immunotherapy.
New oceanic research provides clear evidence of a human “fingerprint” on climate change and shows that specific signals from human activities have altered the seasonal cycle amplitude of sea surface temperatures (SST).
Study shows AI improves performance for some radiologists but worsens it for others. Understanding who might benefit from AI and who would not is critical for designing tools that boost human performance.
Many studies on the climate crisis focus on researching temperature extremes on a global scale. Scientists at the University of Vienna have now uncovered an error in an established calculation method, leading to a systematic underestimation in the frequency of heat days.
A research team led by the University of California, Irvine has discovered the key role that the APOBEC3A and APOBEC3B enzymes play in driving cancer mutations by modifying the DNA in tumor genomes, offering potential new targets for intervention strategies.
A landmark study, led by Yen-Yu Ian Shih, PhD, at the UNC School of Medicine, shows how neurochemicals can influence blood vessels. The new findings may alter how researchers interpret results from functional magnetic resonance imaging.
Text nudges encouraging people to get the COVID-19 vaccine, which had proven effective in prior real-world field tests, are also effective at prompting people to get a booster. The key in both cases is to include in the text a sense of ownership in the dose awaiting them.
Two progressively degenerative diseases, amyotrophic lateral sclerosis (ALS, commonly known as Lou Gehrig’s disease) and frontotemporal dementia (FTD, recently in the news with the diagnoses of actor Bruce Willis and talk show host Wendy Williams), are linked by more than the fact that they both damage nerve cells critical to normal functioning — the former affecting nerves in the brain and spinal cord leading to loss of movement, the latter eroding the brain regions controlling personality, behavior and language.
For the first time, researchers at the University of Minnesota Twin Cities showed that non-invasive brain stimulation can change a specific brain mechanism that is directly related to human behavior.
Supplementing expecting mothers with acetyl-CoA, a sugar-derived molecule, may ensure proper development of nephrons in developing fetuses, lowering their risk of high blood pressure and chronic kidney disease later in life.
We are all aware of the dangers of pollution to our air, water, and earth. In a letter recently published in Nature Human Behavior, scientists are advocating for the recognition and mitigation of another type of environmental pollution that poses equivalent personal and societal dangers: information overload.
Calder Biosciences, Inc., a next-generation vaccine company, has been published in a Nature Communications article that debuts and validates the application of Calder's '3D Vaxlock' platform technology.
Fungi naturally produce all the ingredients needed for a cruelty-free meat substitute. Our scientists are exploring how tuning the genomes of mushrooms and molds can transform these food sources into gourmet, nutrient-packed meals made with minimal processing and a light environmental footprint.
A new population study led by researcher Tomas Paus , professor of psychiatry and neuroscience at the University of Montreal and researcher at CHU Sainte-Justine, highlights the respective roles of maternal and fetal genes in the growth of the baby's cerebral cortex .
