Dendritic cells are divided into Type 1 (DC1) and Type 2 (DC2) dendritic cells. Each type fulfils different functions: DC1 provide an immune response to bacteria and viruses, DC2 protect against fungal or parasitic infections. In a recent study conducted at MedUni Vienna's Institute of Cancer Research, researchers found that a particular group of proteins plays a major role in the development of Type 1 dendritic cells.

Important milestone for next-generation acceleration experiment

Successful navigation requires the ability to separate memories in a context-dependent manner. For example, to find lost keys, one must first remember whether the keys were left in the kitchen or the office. How does the human brain retrieve the contextual memories that drive behavior? J.B. Julian of the Princeton Neuroscience Institute at Princeton University, USA, and Christian F. Doeller of the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany, found in a recent study that modulation of map-like representations in our brain's hippocampal formation can predict contextual memory retrieval in an ambiguous environment.

Scientists at the University of Nottingham have developed an ultrasonic imaging system, which can be deployed on the tip of a hair-thin optical fibre, and will be insertable into the human body to visualise cell abnormalities in 3D.

Shortage of DNA building blocks in the cell releases mitochondrial DNA

The Brazilian Amazon rainforest released more carbon than it stored over the last decade - with degradation a bigger cause than deforestation - according to new research.

Medical researchers at Flinders University have established a new link between high body mass index (BMI) and breast cancer survival rates -- with clinical data revealing worse outcomes for early breast cancer (EBC) patients and improved survival rates in advanced breast cancer (ABC).

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have created a new gene editing tool called Retron Library Recombineering (RLR) that can generate up to millions of mutations simultaneously, and "barcodes" mutant bacterial cells so that the entire pool can be screened at once. It can be used in contexts where CRISPR is toxic or not feasible, and results in better editing rates.

Salk researchers and collaborators show how the novel coronavirus spike protein damages cells, confirming COVID-19 as a primarily vascular disease.

A new study, presented today at the AATS 101st Annual Meeting, found that severely ill COVID-19 patients treated with ECMO did not suffer worse long-term outcomes than other mechanically-ventilated patients.

Multi-site study of pediatric and adult patients shows cfDNA holds promise as a non-invasive biomarker to assess for risk of rejection following heart transplantation.

A new study finds Black patients are more likely to die after their heart bypass surgery if they're at a hospital where some care teams see mostly white patients and others see mostly Black patients. On the other hand, mortality rates are comparable between Black and white patients after heart bypass surgery when the teams of health care providers at their hospitals all care for patients of all races.

Researchers have identified a vulnerability in some cases of acute myeloid leukaemia that could be harnessed for targeted treatment of these poor-prognosis cancers

The Worldwide Innovative Network - WIN Consortium in personalized cancer medicine announces the publication in NPJ Precision Oncology of the Digital Display Precision Predictor (DDPP) global biomarker prototype to guide the selection of targeted therapy and predict the progression-free survival for cancer patients.

The researchers from DICP of CAS revealed oxygen production from the three-body photodissociation of water molecule using the Dalian Coherent Light Source.

Researchers developed new synaptic transistors that can mimic the human brain's plasticity by simultaneously processing and storing data. After connecting transistors into a device, researchers conditioned it to associate light with pressure -- similar to how Pavlov's dog associated a bell with food.

In a mouse study, National Institutes of Health researchers have identified and mapped a diverse spectrum of motor neurons along the spinal cord.

Jeremy Edwards, director of the Computational Genomics and Technology (CGaT) Laboratory at The University of New Mexico, and his colleagues at Centrillion Technologies in Palo Alto, Calif. and West Virginia University, have developed a chip that provides a simpler and more rapid method of genome sequencing for viruses like COVID-19.

Scientists from around the world have produced a new analysis--believed to be the most detailed study of specialized ecological data from global forests--that is furthering science's understanding of species interactions and how diversity contributes to the preservation of ecosystem health.

Prof. YAN Yihua and his research team from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) recently released detailed results of observations by the new generation solar radio telescope--Mingantu Spectral Radio Heliograph (MUSER)--from 2014 to 2019.
