| 'Neuroprosthesis' restores words to man with paralysis Posted: 14 Jul 2021 02:41 PM PDT Researchers have successfully developed a 'speech neuroprosthesis' that has enabled a man with severe paralysis to communicate in sentences, translating signals from his brain to the vocal tract directly into words that appear as text on a screen. |
| Scientists provide a more strategic approach to COVID-19 testing Posted: 14 Jul 2021 10:20 AM PDT With few additional targeted tests and non-invasive surveys, public health agencies can better estimate disease occurrence and trends, changes in transmission, rates of hospitalization and death and effectiveness of vaccines and other control measures. |
| Short chain fatty acids: An 'ace in the hole' against SARS-CoV-2 infection Posted: 14 Jul 2021 10:19 AM PDT Scientists find that short chain fatty acids can be used to reduce susceptibility to SARS-CoV-2 infection and mortality from COVID-19. |
| Posted: 14 Jul 2021 10:19 AM PDT More and more companies are using chatbots in customer services. Due to advances in artificial intelligence and natural language processing, chatbots are often indistinguishable from humans when it comes to communication. But should companies tell customers they are communicating with machines and not with humans? Researchers investigated. Their research found that consumers tend to react negatively when they learn that the person they are talking to is, in fact, a chatbot. |
| Electroconvulsive therapy linked to longer hospital stays, increased costs Posted: 14 Jul 2021 10:18 AM PDT Electroconvulsive therapy, which may be effective at lowering long-term risks of suicide and death among patients with certain mood disorders, may result in longer hospital stays and increased health care costs, according to researchers. They said delivering the therapy in outpatient settings may make the treatment more cost-effective. |
| Scientists identify new gut-liver drug recycling process Posted: 14 Jul 2021 10:18 AM PDT A team of pharmaceutical researchers is reporting a newly recognized process of drug metabolism in the intestines - followed by recycling through the liver - that could have important implications for developing treatments for intestinal diseases and for taking multiple medications at the same time. |
| How to make biomedical research data able to interact? Posted: 14 Jul 2021 08:06 AM PDT Interoperability describes the ability of different systems to communicate. Scientists have now developed the strategy for a national infrastructure adopted by Swiss university hospitals and academic institutions. With its pragmatic approach, this strategy is based on the development of a common semantic framework that does not aim to replace existing standards, but to use them in a synergistic and flexible way according to the needs of the research and the partners involved. |
| Conversion of genetic information from DNA to proteins: role of mRNA Posted: 14 Jul 2021 08:06 AM PDT mRNA plays a key role in the conversion of genetic information from DNA to proteins. Their production is a delicate process. A research team has now identified a crucial factor. |
| Metal-based molecules show promise against the build-up of Alzheimer's peptides Posted: 14 Jul 2021 08:05 AM PDT In lab tests, researchers have created a metal-based molecule that inhibits the build-up of a peptide associated with Alzheimer's disease. |
| Personalized 3D printed knee implant could help thousands of arthritis sufferers Posted: 14 Jul 2021 08:05 AM PDT Pioneering 'printed metal' procedure to create bespoke treatment for early knee osteoarthritis set to be trialed in the UK following MHRA approval. |
| Study highlights need to replace 'ancestry' in forensics with something more accurate Posted: 14 Jul 2021 08:05 AM PDT A new study finds forensics researchers use terms related to ancestry and race in inconsistent ways, and calls for the discipline to adopt a new approach to better account for both the fluidity of populations and how historical events have shaped our skeletal characteristics. |
| Idea sharing increases online learner engagement Posted: 14 Jul 2021 08:05 AM PDT Online learning engagement can be increased by nearly one-third by simply prompting students to share course ideas rather than personal details in the form of icebreakers and social introductions. |
| Signaling molecule may help prevent Alzheimer's disease Posted: 14 Jul 2021 08:05 AM PDT The main driver of Alzheimer's disease is excessive inflammation in the brain that is triggered by cells called astrocytes and microglia in response to high levels of amyloid beta deposits and tau tangles. New research reveals that a subset of astrocytes releases a molecule called interleukin-3 that instructs microglia to adopt a protective response and clear away amyloid beta deposits and tau tangles. Interleukin-3 may hold promise as a new therapeutic intervention in Alzheimer's disease. |
| Fungi that live in the gut influence health and disease Posted: 14 Jul 2021 08:05 AM PDT Bacteria's role in gut health has received attention in recent years. But new research shows that fungi -- another microorganism that lives within us -- may be equally important in health and disease. Fungi thrive in the healthy gut, but when interactions with the immune system are off-balance, they cause intestinal damage that may contribute to gastrointestinal disease. Additional investigation demonstrate that vaccines could be developed as therapeutics to improve gut health. |
| Study reveals new aspects of gingivitis and body's response Posted: 14 Jul 2021 08:05 AM PDT Researchers have identified and classified how different people respond to the accumulation of dental plaque. |
| Compound derived from turmeric essential oil has neuroprotective properties Posted: 14 Jul 2021 08:04 AM PDT Researchers have found that a component derived from turmeric essential oil, ar-turmerone, and its derivatives act directly on dopaminergic neurons to exert a neuroprotective effect on tissue cultures of a Parkinson's disease model. The effect appears to be due to the enhancement of cellular antioxidant potency through Nrf2 activation. The researchers believe that the ar-turmerone derivatives identified in this study can be utilized as new therapeutic agents for Parkinson's disease. |
| Methamphetamine use drove surge in heart failure hospitalizations, costs in California Posted: 14 Jul 2021 08:04 AM PDT Methamphetamine-related heart failure hospitalizations rose a staggering 585% between 2008 and 2018 in California. Costs associated with methamphetamine-related hospitalizations in California jumped even higher, 840%. |
| Like priming a pump, cells damaged by chronic lung disease can result in severe COVID Posted: 14 Jul 2021 08:04 AM PDT New research suggests that the airway cells of patients with chronic lung diseases are 'primed' for infection by the COVID-19 virus, resulting in more severe symptoms, poorer outcomes and a greater likelihood of death. |
| Drug combination shows meaningful responses for malignant peritoneal mesothelioma patient Posted: 14 Jul 2021 08:04 AM PDT A phase II study found that treatment with atezolizumab and bevacizumab was well-tolerated and resulted in a 40% objective response rate in patients with advanced malignant peritoneal mesothelioma, a rare cancer in the lining of the abdomen. |
| Vaccine hesitancy in young adults may hamper herd immunity Posted: 14 Jul 2021 08:04 AM PDT Vaccine skepticism among young adults may stall efforts to achieve herd immunity -- a threshold in which approximately 80 percent of a population is vaccinated against the coronavirus. |
| New study links moderate alcohol use with higher cancer risk Posted: 14 Jul 2021 08:04 AM PDT A new study has found an association between alcohol and a substantially higher risk of several forms of cancer, including breast, colon, and oral cancers. Increased risk was evident even among light to moderate drinkers (up to two drinks a day), who represented 1 in 7 of all new cancers in 2020 and more than 100,000 cases worldwide. |
| Liquid metal sensors and AI could help prosthetic hands to 'feel' Posted: 14 Jul 2021 08:03 AM PDT Prosthetics currently lack the sensation of 'touch.' To enable a more natural feeling prosthetic hand interface, researchers are the first to incorporate stretchable tactile sensors using liquid metal and machine learning. This hierarchical multi-finger tactile sensation integration could provide a higher level of intelligence for artificial hands by improving control, providing haptic feedback and reconnecting amputees to a previously severed sense of touch. |
