Scientists at the Kennedy Institute of Rheumatology in the Nuffield Department of Orthopaedics, Rheumatology and Musculoskeletal Sciences have discovered a new way for T cells to attack cells infected by viruses or deranged by cancer.
Published online by the journal Science on Thursday 7 May 2020, the new research from the Dustin Group describes the structure and composition of supramolecular attack particles (SMAPs) and their role in killing targeted cells.
When magnetic materials are nanometric at least in one dimension, the surface effect often dominates the static and transport behaviors due to the limited long-range order and broken translation symmetry. The perturbations in spin-spin correlation length and unperfect spin coordination structures make low-dimensional magnetic materials an ideal platform for exploring magnetism in reduced dimensions.
Barcelona, 12 May, 2020.- Tumours are not a uniform mass of cells. Colon cancers bear differentiated-like cells, similar to the functional cells of the intestinal wall, and pluripotent cells--the so-called tumour stem cells. The latter fuel tumour growth and cause metastasis.
In a new study, researchers from the University of Copenhagen have discovered two important functions of a protein called RTEL1 during cell division. The researchers hope that the new knowledge will help to find new cancer treatments.
One of the body's most important processes is cell division, which occurs throughout life. Normal cells only have a limited number of divisions, while in cancer cells the cell division goes awry and is uncontrollable.
Two important phases
Walking is one of the most important motor skills for animals and humans. And for almost all people, being able to walk is deeply essential. In spite of this, researchers are still working to map out which signals and electrical impulses from the brain control our walking.
The 17 SDGs and 169 targets set out in the 2030 Agenda set the direction for countries around the world to work on sustainable development from 2015 to 2030. After more than four years, various countries have made a series of breakthroughs. However, recent reports indicate that, based on current progress, there is no guarantee that all goals will be achieved by 2030, and that more in-depth and rapid measures will be needed to advance the implementation of SDGs.
Hydrogen flames can propagate even with very little fuel, within surprisingly narrow gaps and can extend breaking up into fractal patterns. That is the unexpected physical behavior of this gas when it burns, which has been detected by a scientific team led by researchers from Universidad Carlos III de Madrid (UC3M). These results can help to improve the safety of Hydrogen-powered devices.
Transcranial direct current stimulation, tDCS, is a promising treatment for conditions such as depression and addictive disorders. New evidence on the safety of transcranial direct current stimulation was recently offered by a new study showing that tDCS does not affect metabolism.
Transcranial direct current stimulation is a non-invasive method for modulating neuronal activity by introducing a small electric current into the brain via electrodes placed on the scalp.
Researchers at Karolinska Institutet in Sweden show that different measures of psychopathology can be combined into a single factor, "p", which predicts the patient's prognosis and need of extra support. The general factor of psychopathology reflects the overall risk of adverse psychiatric outcomes with an accuracy equal to that currently used for intelligence, they report in a paper published in World Psychiatry.
Platelets not only play a key role in blood clotting, but can also significantly intensify inflammatory processes. This is shown by a new study carried out by scientists from the University of Bonn together with colleagues from Sao Paulo (Brazil). In the medium term, the results could open up new ways to treat autoimmune diseases. They have now been published in the renowned journal Cell Reports.
The ability to accurately detect changes in ecosystem biodiversity caused by human activity has long challenged environmental scientists and ecologists, but a new study, published in PNAS, has established new DNA-based methods that are effective for environmental assessment and monitoring.
Researchers from Lingnan University of Hong Kong published a new paper in the Journal of Marketing that examines the role that facial attractiveness has in social selling.
The study forthcoming in the Journal of Marketing is titled "The Faces of Success: Beauty and Ugliness Premiums in Online Platforms" and is authored by Ling Peng, Geng Cui, Yuho Chung, and Wanyi Zheng.
The long-term effects of climate change suggests that the butterfly effect is at work on butterflies in the alpine regions of North America, according to a new study by University of Alberta scientists--and the predictions don't bode well.
A team of researchers from the Biology Centre Czech Academy of Sciences (Budweis, Czechia), MARUM - Center for Marine Environmental Sciences at the University of Bremen (Germany), and Max Planck Institute for Marine Microbiology (Bremen, Germany) have estimated that these chemoautotrophs recycle approximately 5 per cent of the carbon and phosphorus assimilated by marine algae and release terragrams (1012 g) of dissolved organics to the ocean interior each year. These findings are now published in the journal Science Advances.
Announcing a new article publication for BIO Integration journal. In this review article the authors Jing Liu, Mengze Xu and Zhen Yuan from University of Macau, Macau SAR, China consider immunotherapy for the treatment of tumors.
