Neurons, nerve cells in the brain, are central players in brain function. However, a key role for glia, long considered support cells, is emerging. A research group at the University of Basel has now discovered two new types of glial cells in the brain, by unleashing adult stem cells from their quiescent state. These new types of glia may play an important role in brain plasticity and repair.

Successful pilot project to tackle discrimination 13 June is International Albinism Awareness Day One in 1,400 people in Tanzania has albinism. These people are often socially excluded, heavily discriminated against and sometimes even have to fear for their lives. Dr Tjitske de Groot of the Vrije Universiteit Brussel set up a pilot project for her doctoral research and investigated what actions and means could be used to reduce the stigma of albinism - as well as other stigma - and actively contributed to this on site.
An international team of researchers has shed new light on the way viruses evolved highly effective ways of spreading disease. The scientists, involving a team from the universities of Leeds and York, believe understanding that key moment in the natural history of viruses may eventually help with the design of novel delivery mechanisms for gene therapies, where viruses are used to repair faulty genes.

Trust is an issue when it comes to artificial intelligence (AI) according to a University of Queensland study that found 72 per cent of people don't trust it, with Australians leading the pack. Trust experts from UQ Business School, Professor Nicole Gillespie , Dr Steve Lockey and Dr Caitlin Curtis led the study in partnership with KPMG, surveying more than 6000 people in Australia, the US, Canada, Germany and the UK to unearth attitudes about AI.
Astronomers have spotted a giant 'blinking' star towards the centre of the Milky Way, more than 25,000 light years away. There are certainly more to be found, but the challenge now is in figuring out what the hidden companions are, and how they came to be surrounded by discs, despite orbiting so far from the giant star Leigh Smith An international team of astronomers observed the star, VVV-WIT-08, decreasing in brightness by a factor of 30, so that it nearly disappeared from the sky.
Researchers at ETH Zurich have recreated a key step in the evolutionary history of viruses in a laboratory experiment. They succeeded in remodeling a natural protein to create capsids capable of storing genetic material. Viruses have always had a major influence on life. They emerged a few billion years ago, precisely when is difficult to estimate.
Researchers at the University of Washington have developed a method that uses smartphone-derived images to identify potentially harmful bacteria on skin and in oral cavities. Their approach, outlined in a paper published in the May issue of Optics and Lasers in Engineering, can visually identify microbes on skin contributing to acne and slow wound healing, as well as bacteria in the oral cavity that can cause gingivitis and dental plaques.
Insulator strings connect the live conductor to overhead-line towers. Researchers at TU Graz simulated for the first time when and under what conditions different loads act on these strings. Overhead lines will thus be made even safer. Another picture for download can be found at the end of the text Though small and inconspicuous, they literally play a supporting role in the operational safety of high-voltage lines: insulator strings.
A robotic 'evolution machine' capable of exploring the generational development of chemical mixtures over long periods of time could help cast new light on the origins of life, scientists say. A team of chemists from the University of Glasgow developed the robot, which uses a machine-learning algorithm to make decisions about which chemicals from a selection of 18 to combine in a reactor, and how to set conditions under which the reaction occurs.
Researchers have created a plant-based, sustainable, scalable material that could replace single-use plastics in many consumer products. It was a surprise to find our research could also address a big problem in sustainability: that of plastic pollution Tuomas Knowles The researchers, from the University of Cambridge, created a polymer film by mimicking the properties of spider silk, one of the strongest materials in nature.
This latest report from Bristol's NCMD programme, which gathers information on all children who die in England below the age of 18 years, analysed the characteristics of the 3,347 child deaths between 1 April 2019 and 31 March 2020 in England, and found that the majority of children who died (63 per cent) in this period were under one year old.
New climate reconstruction method provides precise picture of climate 78 million years ago Palaeoclimatologists study climate of the geological past. Using an innovative technique, new research by an international research team led by Niels de Winter (VUB-AMGC & Utrecht University) shows for the first time that dinosaurs had to deal with greater seasonal differences than previously thought.
The annual number of new HIV infections among men who have sex with men in England is likely to have fallen dramatically, from 2,770 in 2013 to 854 in 2018, showing elimination of HIV transmission by 2030 to be within reach - suggests work by researchers from the MRC Biostatistics Unit at the University of Cambridge and Public Health England, published in The Lancet HIV .
Biochemists discover highly selective phage activation based on signal molecule Bacteriophages are still a relatively unknown component of the human microbiome. However, they can play a powerful role in the life cycles of bacteria. Biochemist Thomas B÷ttcher from the University of Vienna and PhD candidate Magdalena Jancheva were able to show for the first time how Pseudomonas bacteria use a self-produced signal molecule to selectively manipulate phages in a competing bacterial strain to defeat their enemy.
Screening and early interventions to address loneliness, sleep disturbances and alcohol consumption can help to reduce the association between being bullied at school and suicidal behaviours, a new study has found. Researchers from The University of Queensland's Life Course Centre examined the relationship between bullying victimisation and suicidal behaviours in more than 280,000 teenagers aged 13-17 in 90 countries worldwide.
In a major scientific leap, University of Queensland researchers have created a quantum microscope that can reveal biological structures that would otherwise be impossible to see. This paves the way for applications in biotechnology, and could extend far beyond this into areas ranging from navigation to medical imaging.
Some four months ago, a devastating flood ravaged the Chamoli district in the Indian Himalayas, killing over 200 people. The flood was caused by a massive landslide, which also involved a glacier. Researchers at the University of Zurich, the WSL and ETH Zurich have now analyzed the causes, scope and impact of the disaster as part of an international collaboration.
Astronomers from the School of Physics and Astronomy have joined the Science Team of the Twinkle space mission, a pioneering space telescope designed to study the atmospheres of exoplanets - planets orbiting stars beyond our solar system. Twinkle will be launched in 2024 and will operate for seven years, making sensitive visible and infrared spectroscopic measurements to detect molecules in the atmospheres of planets as they pass in front of their host stars.
A class of drug called monoamine oxidase inhibitors is commonly prescribed to treat depression; the medications work by boosting levels of serotonin, the brain's "happiness hormone." A new study by UCLA researchers suggests that those drugs, commonly known as MAOIs, might have another health benefit: helping the immune system attack cancer.
Giving birth can be a joyous, yet stressful experience in the best of times - but what happens when a global public health crisis is thrown into the mix? McGill University and the University of Toronto researchers examined the effects certain pandemic policies have had on the mental health of Canadian women who gave birth during the COVID-19 pandemic.
