Cells from healthy individuals with major depressive disorder were found to have higher than expected rates of methylation at specific sites on their DNA, when compared to cells from healthy individuals without MDD, according to a study by a multidisciplinary team of Walter Reed Army Institute of Research and University of California San Francisco scientists, in collaboration with others.
New Haven, Conn. -- Alzheimer's disease is known for its slow attack on neurons crucial to memory and cognition. But why are these particular neurons in aging brains so susceptible to the disease's ravages, while others remain resilient?
WEST LAFAYETTE, Ind. - New insights into the immune response to SARS-CoV-2 infections could bring better treatments for COVID-19 cases.
An international team of researchers unexpectedly found that a biochemical pathway, known as the immune complement system, is triggered in lung cells by the virus, which might explain why the disease is so difficult to treat. The research is published this week in the journal Science Immunology.
When most Americans imagine an archaeologist, they picture someone who looks like Indiana Jones. Or, perhaps, Lara Croft, from the Tomb Raider game. White, usually male but occasionally female, digging up the spoils of a vanished culture in colonized lands.
Many Mario Kart enthusiasts are familiar with the rush of racing down Rainbow Road, barely squeaking around a corner, and catching a power-up from one of the floating square icons on the screen—or, less ideally, slipping on a banana peel laid by another racer and flying off the side of the road into oblivion. This heated competition between multiple players, who use a variety of game tokens and tools to speed ahead or thwart their competitors, is part of what makes the classic Nintendo racing game that has been around since the early 1990s so appealing.
A new clinical trial from King's College London's Institute of Psychiatry, Psychology, & Neuroscience, in collaboration with Oxford University, Oxford Health NHS Foundation Trust, Sussex University, and Sussex Partnership NHS Foundation Trust has established an innovative therapy as an effective means of treating paranoid thoughts in people experiencing psychosis.
CORVALLIS, Ore. - Eucalyptus, a pest-resistant evergreen valued for its hardy lumber and wellness-promoting oil, can be genetically modified not to reproduce sexually, a key step toward preventing the global tree plantation staple from invading native ecosystems.
Oregon State University's Steve Strauss led an international collaboration that showed the CRISPR Cas9 gene editing technique could be used with nearly 100% efficiency to knock out LEAFY, the master gene behind flower formation.
Two thirds of New Zealanders believed there were 'silver linings' to the country's Alert Level 4 COVID-19 lockdown imposed in March last year, a University of Otago survey has found.
The researchers were able to question New Zealanders while they were at home, giving a unique insight into their lives during the nationwide lockdown between 25 March and 23 April, widely regarded as one of the strictest imposed anywhere in the world.
One year on from lockdown, the results of their study have been published in the international scientific journal, PLOS ONE.
Can a mirror turn an orange into a doughnut? The answer is definitely no in the real (macro) world. But at the nanoscale, a mirror can turn an "orange" shaped pattern into a "doughnut" shaped pattern by overlapping the "orange" with its reflected mirror image.
A team of researchers from the University of Technology Sydney (UTS) has shown for the first time that fluorescent nanoparticles placed near a mirror generate unique patterns that can be used to pinpoint their location.
Areas with a relatively greater amount of misogynistic tweets have higher incidences of domestic and family violence, a UNSW study has found.
The study, published in Psychological Science, not only found this connection with domestic and family violence carried over from one year to the next, but also occurred despite the 'usual suspects' of domestic violence, such as alcohol and inequality.
Examples of misogynistic tweets identified by the researchers included, "Women are all bitches," "Whore had it coming," and, "Make me a sandwich, slut."
Sweden's acclaimed research on uterine transplants has taken a new step forward: into the field of health economics. Now, for the first time, there is a scientifically based estimate of how much implementing the treatment costs.
The current research is based on the nine uterine transplants from living donors carried out in 2013, under the leadership of Mats Brännström, Professor of Obstetrics and Gynecology at Sahlgrenska Academy, University of Gothenburg, and Chief Physician at Sahlgrenska University Hospital.
Tsukuba, Japan - Dermatomyositis is an idiopathic inflammatory myopathy that has been regarded as an autoimmunity-based disorder, although its pathogenesis remains unclear. In this study, researchers from the University of Tsukuba used a mouse model to identify a mechanism by which dermatomyositis may develop in humans. The animal model and findings can be used to better understand the disease and develop disease-specific treatments.
The landscape of sloping vineyards on the banks of the River Mosel in Germany is a characteristic symbol of a region, which cannot be understood without its wine: the Mosel wine region. Tourists from all over the world, especially from the neighbouring countries of Belgium, Luxembourg, and The Netherlands visit the area in search of mountains and wine. However, the lack of new generations and the increase in temperatures and short heavy summer rainfall events caused by climate change endanger the production of wine.
The way we move says a lot about the state of our brain. While normal motor behaviour points to a healthy brain function, deviations can indicate impairments owing to neurological diseases. The observation and evaluation of movement patterns is therefore part of basic research, and is likewise one of the most important instruments for non-invasive diagnostics in clinical applications. Under the leadership of computer scientist Prof.
To effectively perform any daily task, the human brain needs to process information from the outside world using various cognitive functions. This cognitive processing passes through a dense interconnected network of cells whose physiology is specialized. The interconnected cell network needs to perform this processing of information efficiently and interact cooperatively to provide us, in real time, with useful instructions for living.
